Brief summary:
Main Study:

Primary Objective:

Assess the long term safety of sarilumab in participants with rheumatoid arthritis (RA).

Secondary Objective:

Assess the long term efficacy of sarilumab in participants with RA.

Sub-Study:

This phase 3, open label sub-study was aimed to assess the usability of PFS-S when used by participants with moderate or severe RA, or their professional or non-professional healthcare providers in an unsupervised real-world situation. To mimic the real-world practice, the sub-study was incorporated into the LTS11210 study without additional visits compared to the scheduled visits in the main study. The duration of this sub-study was 12 weeks.

Detailed description:
The maximum duration of the study was up to 523 weeks:

* Up to 1-week of screening, if any.
* At least 264 weeks of open label treatment phase and up to 516 weeks as maximum.
* 6-week post-treatment follow-up as required per protocol.

Arms:
arm 1: Participants who completed any of initial studies:Part A or B of EFC11072, ACT11575, EFC10832 or SFY13370 were enrolled in LTS11210 and received sarilumab 150 milligrams (mg) subcutaneously (SC) once weekly (qw). Dose could be reduced to 150 mg every 2 weeks (q2w) due to neutropenia, thrombocytopenia or increase in liver enzymes (alanine aminotransferase \[ALT\]). After dose regimens selection for Phase 3 studies (150 mg q2w and 200 mg q2w), participants already receiving 150 mg qw were switched to sarilumab 200 mg q2w. Treatment duration per participant was at least 264 weeks from first study drug administration in LTS11210. Participants continued to be treated beyond 264 weeks until sarilumab was commercially available in their respective countries or until 2020, at the latest (maximum duration: 523 weeks). Participants who were already taking concomitant non-biologic DMARDs in initial study continued stable dose of one or combination of conventional synthetic DMARDs they were taking. arm 2: Participants who completed study EFC13752 were enrolled in LTS11210 and received sarilumab 200 mg q2w. Dose could be reduced to 150 mg q2w due to neutropenia, thrombocytopenia or increase in liver enzymes (ALT). Treatment duration per participant was at least 264 weeks from first study drug administration in LTS11210. Participants continued to be treated beyond 264 weeks until sarilumab was commercially available in their respective countries or until 2020, at the latest (maximum duration: 523 weeks).

CLINICAL TRIAL SUMMARY 
COMPOUND:  Sarilumab 
STUDY No.:  LTS11210 
TITLE 
A multi-center, uncontrolled extension study evaluating the efficacy 
and safety of sarilumab in patients with active Rheumatoid Arthritis 
(RA). 
INVESTIGATOR/TRIAL LOCATION 
Worldwide 
STUDY OBJECTIVE(S) 
To document the long term safety and efficacy of sarilumab. 
STUDY DESIGN 
An uncontrolled open label extension study of sarilumab 200 mg 
every other week (q2w); lasting 264 weeks from the first IMP 
administration in LTS11210. In addition the patients will continue to 
be treated beyond 264 weeks until sarilumab is commercially 
available in their country or until 2020 at the latest when the study 
will be closed. (In the UK the duration of treatment will be 264 weeks 
from the first study drug administration in LTS11210). At the time of 
inclusion in this long-term extension, patients may have been 
exposed to sarilumab or placebo or active comparator for 2 to 52 
weeks, depending on the study in which they were initially included. 
The sarilumab dose is reduced to 150 mg q2w in case of 
neutropenia, thrombocytopenia, or an increase in liver enzymes 
(alanine aminotransferase (ALT).  
A 12-week optional sub-study to evaluate the usability of pre-filled 
syringe with safety system (PFS-S) will be conducted in some 
countries. Patients in selected sites in those countries may be 
offered the opportunity to participate in this PFS-S sub-study.

STUDY TREATMENT(s) 
 
Investigational Medicinal Product(s) 
 
Formulation 
Sarilumab (anti-Interleukin 6Rα monoclonal antibody (Anti-IL6Rα 
mAb)   
Two different pharmaceutical forms are used in the study: C1F2 
used in vials and C2F3 (pivotal formulation) used in prefilled 
syringes. 
Before Phase 3 pivotal dose selection decision:  vials 150 mg 
(75 mg/ml)  
After Phase 3 pivotal dose selection decision, and prior to 
availability of prefilled syringes: vials 150 mg (75 mg/mL), and 
200 mg (100 mg/mL)  
After Phase 3 pivotal dose selection decision, upon availability 
of prefilled syringes:   prefilled syringes filled with 150 mg 
(131.6 mg/ml) or 200 mg (175 mg/ml) of drug product 
In the sub-study: prefilled syringes with a needle safety shield 
(PFS-S) with exactly the same IMP formulation as the PFS used in 
the main study  
Route(s) of administration: 
Subcutaneous (SC) injection in the abdomen, thigh, or upper arm 
Injection volume: 2 mL (vials); 1.14 mL (prefilled syringes) 
Dose regimen: 
Before the phase 3 pivotal dose selection decision, the sarilumab 
dose was 150 mg weekly (qw) (dose reduction to 150 mg q2w in 
case of neutropenia, thrombocytopenia, or an increase in liver 
enzymes (ALT). 
After the phase 3 pivotal doses were selected; the sarilumab dose is 
200 mg q2w and the reduced dose is 150 mg q2w.  
Note: Patients enrolled in the study prior to the dose selection 
decision and receiving 150 mg qw were switched to 200 mg q2w. 
Patients who prior to the dose selection decision were assigned to 
the step-down dose of 150 mg q2w because of a safety issue 
continued to receive sarilumab 150 mg q2w. 
Noninvestigational Medicinal Products 
(except EFC13752 patients) 
One or a combination of non-biologic disease modifying drugs 
(DMARDs).

ASSESSMENT SCHEDULE 
The last visit (EOT visit) of EFC11072, ACT11575, EFC10832, 
SFY13370, or EFC13752 will be used as the initial LTS11210 visit. 
All patients who agree to participate in the LTS11210 will need to 
sign a new informed consent form specific for this study.  At D1, after 
confirmation of eligibility, patients will be enrolled in the LTS11210 
study.  
Patients will have site visits at weeks 4, 8, and 12, then every 
12 weeks until the 2nd year of treatment in the study (Week 96). 
After 2 years of study participation, safety assessment and 
laboratory tests will take place at 24-week intervals. In addition, there 
will be visits at 24-week intervals in between regular study visits for 
distribution of IMP kits and recording of AEs only (in Portugal and 
Sweden, hematology and liver function test evaluations will be 
performed at all IMP dispensing visits until end of treatment) . After 
264 weeks in LTS11210, some assessments will no longer be 
required in either scheduled visits or EOT visit (see Section 1.2).  
Additional laboratory testing (central) including hematology and liver 
function tests will be performed at week 2, week 6, and week 10 (site 
or home visits). 
Efficacy assessments will be performed at Weeks 0, 4, 8, 12 and 
then every 12 weeks up to Week 96 and then every 24 weeks until 
the end of treatment. 
Health economic assessments and Patient Reported outcomes 
(PROs) defined per initial study will be performed every 12 weeks up 
to Week 96 and then every 24 weeks until Week 264.  PROs will not 
be assessed after Week 264, including EOT if EOT is after Week 
264. 
Patients who completed EFC11072 Part B will have an additional 
X-ray evaluation at week 48, 96, 144, 192 (±14 days for each 
evaluation) or at EOT if EOT prior to Week 192.  
Electrocardiograms (ECGs) will be performed at the initial visit, week 
48, 96, 144, 192, 240 and 264 or EOT. ECGs will not be performed 
after Week 264, including EOT if EOT is after Week 264. 
Adverse events will be collected throughout the study. 
Pharmacokinetic samples will be collected at V1 or V1/V2, V4 
(Week 4), V7 (Week 12),  every 12 weeks thereafter through year 2 
and then every 24 weeks until the end of treatment and at the 
Post-Treatment follow-up visit 6 weeks after the end of treatment.

Specific serum samples will be taken during the study to test for anti-
drug antibody to sarilumab at week 12, every 12 weeks thereafter 
through year 2 and then every 24 weeks until the end of treatment 
and at the Post-Treatment follow-up visit 6 weeks after the end of 
treatment. 
Serum samples to store for future biomarker analyses will be 
collected at the initial visit, week 2, 12, and 48 (except for EFC13752 
patients). Whole blood to store for future ribonucleic acid (RNA) 
expression analysis will be collected at week 0 (baseline) and week 
2, except for patients from study SFY13370 and EFC13752. 
There will be a 6-week post treatment observation period for patients 
with early discontinuation and for patients who completed the 
planned treatment period. In patients who complete sarilumab 
treatment per protocol in countries where sarilumab is commercially 
available the post treatment follow-up visit may be cancelled if the 
patient initiates treatment with commercial sarilumab during the post 
treatment follow-up period. However, in this case, a telephone 
contact must be established with the patient to capture all AEs 
occurring up to the 1st administration of commercial sarilumab. 
STATISTICAL CONSIDERATIONS 
 
Patient Population: 
The primary analysis population will be safety population which is 
defined as all patients who have received at least one dose of 
treatment.   
Analysis Methods: 
The safety analyses will be based on the reported adverse events, 
clinical laboratory evaluations, vital signs, and 12-lead ECGs. The 
number and proportion of patients who experience an adverse event 
will be summarized by treatment group.  Other categorical variables 
will be described in the same way.  Continuous variables will be 
described using the mean, standard deviation, median, minimum 
and maximum.  All summaries will be based on observed cases only; 
missing response data will not be imputed. 
For efficacy variables, descriptive statistics will be provided and 95% 
confidence intervals will be calculated if appropriate. 
Descriptive statistics will be provided for the van der Heijde modified 
total Sharp score for the subset of patients who previously 
completed study EFC11072, Part B. 
Data analysis results for patients who roll over from the EFC13752 
study will be presented separately as sarilumab is administered as 
monotherapy in the EFC13752 and these patients will continue to be 
on sarilumab monotherapy in the LTS11210 study. 
DURATION OF STUDY PERIOD (per 
patient)  
Duration of the study treatment will be at least 264 weeks from the 
first study drug administration in LTS11210, or until sarilumab is 
commercially available in the patient’s country whichever later, but 
no later than 2020 when the study will be closed. (In the UK the 
duration of treatment will be 264 weeks from the first study drug 
administration in LTS11210).  
The maximum duration of the study is expected to be approximately 
523 weeks: 
Up to 1-week of screening, if any

a EOT visit and follow up visit 6 weeks later should be completed for all patients at the end of treatment (in patients who complete sarilumab treatment per protocol in countries where sarilumab is commercially 
available the post treatment follow-up visit may be cancelled if the patient initiates treatment with commercial sarilumab during the post treatment follow-up period; however, in this case, a telephone contact must 
be established with the patient to capture all AEs occurring up to the 1st administration of commercial sarilumab). EOT visit may occur when the patients complete 264 weeks of sarilumab treatment from the 
LTS11210, or at any visit thereafter when sarilumab is commercialized in their country, but no later than 2020 when the study will be closed. In case of permanent discontinuation of treatment, the patients will be 
assessed using the procedures normally planned for the EOT visit and the 6 week follow up visit 6 weeks later.  
b From Week 24, patients at limited sites in selected countries may participate in PFS-S sub-study. If the patient enters the sub-study, then the sub-study IMP will be dispensed instead of the main study IMP at the 
entry into sub-study and IMP compliance with sub-study IMP will be reviewed at the end of sub-study. Full details of the sub-study are provided in Appendix R  
c HV: Visit can be home visit or clinic visit to draw and collect the blood sample only for hematology and LFTs using the designated central laboratory.

d Last treatment visit from the study EFC11072 or ACT11575. Please note that the SF-36 must be completed at the screening visit of the LTS11210 study for patients rolling over from EFC11072 Part A and 
ACT11575 studies.  Please note that the RNA sample must be collected at V2 of the LTS11210 study for patients rolling over from EFC11072. 
e Physical examination to be done at Week 48, 96, 144, 192, 240, 264, 288, 336, 384, 432, 480 and EOT visit.  
f 
Assessment is NOT required when EOT visit is after Week 264. 
g X-ray of hand and feet (only for patients who completed Part B of the study EFC11072 (not performed for Part A patients, or patients from Part B non-selected dose arms) will be done at Weeks 48, 96, 144, 192 
(±14 days for each assessment), and EOT; No X-ray evaluation will be performed after Week 192 including EOT if EOT is after Week 192. Required x-ray must be done after confirmation of negative urine 
pregnancy test in women of child bearing potential. 
h After Week 264, only DAS28 components of ACR core set will be assessed (TJC & SJC for 28 joints, patient´s global assessment of disease activity). 
i 
Hematology:  Hemoglobin, hematocrit, red blood cell (RBC) morphology (if blood cell count is abnormal), white blood cell (WBC) with differential, platelets count. For all patients, a CBC test must be performed 
before or at Visit 3 (using either designated central lab or a local laboratory facility), but not earlier than the 12th day after the first dose of IMP administration in order to confirm that the neutrophil count and platelet 
count are not within the protocol-defined limits for temporary or permanent discontinuation of study drug. 
j 
Liver Function Tests (LFTs): Prothrombin Time (PT), Albumin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total bilirubin, conjugated bilirubin, unconjugated 
bilirubin. PT is NOT required at any visit after Week 264. 
k Lipids (fasting): Total cholesterol (TC), High-Density Lipoprotein (HDL) cholesterol, Low-Density Lipoprotein (LDL) cholesterol, triglycerides, Apolipoprotein A, and Apolipoprotein B. After Week 264, lipids 
(excluding Apolipoprotein A, and Apolipoprotein B ) will only be assessed at Weeks 288, 336, 384, 432, 480 (including EOT if EOT is after Week 264)  
l 
Clinical chemistry (fasting): fasting glucose, total proteins, calcium, sodium, potassium, Lactate Dehydrogenase, (LDH), urea nitrogen and creatinine. Creatinine clearance will be calculated during the study if 
clinical indicated.  
m ANA titer will be done at screening, at Week 48, 96, 144, 192, 240, 264, 288, 336, 384, 432, 480 and EOT visit or sooner if clinical indicated (Anti-ds-DNA only if ANA titer is >1:160) 
n Dipstick urinalysis for:  specific gravity, pH, glucose, blood, ketones, proteins, bilirubin, urobilinogen, nitrite, leukocytes. If any parameter is abnormal, a urinalysis sample should be sent to central laboratory for 
testing. If positive for proteins, microscopic analysis will be performed by central laboratory. 
o After Visit 7 (Week 12) between study visits the patient will have a urine pregnancy test at home on a monthly basis.  Patients will be given sufficient urine pregnancy kits to take home at each successive visit for 
monthly testing up until the final treatment visit. When the testing coincides with a clinical visit as indicated in the flow chart, the results should be reported in the eCRF. No pregnancy test kits will be dispensed at 
EOT.  
p ECG to be done at Weeks 48, 96, 144, 192, 240, 264 or EOT; No ECG will be done after Week 264 including EOT if EOT is after Week 264. 
q Rheumatoid factor only at baseline Visit 2 (Week 0) and at Weeks 48, 96, 144, 192, 240, 264 or EOT. No Rheumatoid factor will be assessed after Week 264 including EOT if EOT is after Week 264. 
r 
If throughout the study a serious adverse event (SAE) occurs in a patient, blood samples should be collected for sarilumab at or near the onset and completion of the occurrence of the event, if possible.  The exact 
date of sample collection and last dose must be recorded on the e-CRF.  
s Serum sample for biomarkers to be collected at screening (ie, the last treatment visit from the EFC11072 or ACT11575), Week 2, Week 12, and Week 48. 
t 
Blood sample for RNA to be collected at Week 0 (baseline, prior to administration of study drug) and Week 2 (at site visit only; cancel RNA collection if home visit). 
u Deleted. 
v Samples for IL-6 to be collected at Screening (ie the last treatment visit from EFC11072 or ACT11575) and at V4 (Week 4), V7 (Week 12), V8 (Week 24), V9 (Week 36), and V10 (Week 48).

a EOT visit and follow up visit 6 weeks later should be completed for all patients at the end of treatment (in patients who complete sarilumab treatment per protocol in countries where sarilumab is commercially 
available the post treatment follow-up visit may be cancelled if the patient initiates treatment with commercial sarilumab during the post treatment follow-up period; however, in this case, a telephone contact 
must be established with the patient to capture all AEs occurring up to the 1st administration of commercial sarilumab). EOT visit may occur when the patients complete 264 weeks of sarilumab treatment from 
LTS11210, or any visit thereafter when sarilumab is commercialized in their country, but no later than 2020 when the study will be closed. (In UK, the duration of treatment will be 264 weeks from the first study 
drug administration in LTS11210).  In case of permanent discontinuation of treatment, the patients will be assessed using the procedures normally planned for the EOT visit and the 6 week follow up visit 6 
weeks later.

b From Week 24, patients at limited sites in selected countries may participate in PFS-S sub-study. If the patient enters the sub-study, then the sub-study IMP will be dispensed instead of the main study IMP at 
the entry into sub-study and IMP compliance with sub-study IMP will be reviewed at the end of sub-study. Full details of the sub-study are provided in Appendix R  
c HV: Visit can be home visit or clinic visit to draw and collect the blood sample only for hematology and LFTs using the designated central laboratory.  
d Last treatment visit from the study EFC11072, EFC10832, SFY13370, or EFC13752.   
e Physical examination to be done at Week 48, 96, 144, 192, 240, 264, 288, 336, 384, 432, 480 and EOT visit 
f 
The assessment is NOT required when EOT visit is after Week 264. 
g X-ray of hands and feet (only for patients who completed Part B of the study EFC11072 will be done at Weeks 48, 96, 144, 192 (±14 days for each assessment), and EOT; No X-ray evaluation will be performed 
after Week 192 including EOT if EOT is after Week 192. Required x-ray must be done after confirmation of negative urine pregnancy test in women of child bearing potential. 
h After Week 264, only DAS28 components of ACR core set will be assessed (TJC & SJC for 28 joints, patient´s global assessment of disease activity). 
i 
Hematology:  Hemoglobin, hematocrit, red blood cell (RBC) morphology (if blood cell count is abnormal), white blood cell (WBC) with differential, platelets count. For all patients, a CBC test must be performed 
before or at Visit 3 (using either designated central or a local laboratory facility) but not earlier than the 12th day after the first dose of IMP administration in order to confirm that the neutrophil count and platelet 
count are not within the protocol-defined limits for temporary or permanent discontinuation of study drug. 
j 
Liver Function Tests (LFTs): Prothrombin Time (PT), Albumin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total bilirubin, conjugated bilirubin, unconjugated 
bilirubin. PT is NOT required at any visit after Week 264. 
k Lipids (fasting): Total cholesterol (TC), High-Density Lipoprotein (HDL) cholesterol, Low-Density Lipoprotein (LDL) cholesterol, triglycerides, Apolipoprotein A, and Apolipoprotein B. After Week 264, lipids 
(excluding Apolipoprotein A, and Apolipoprotein B ) will only be assessed at Weeks 288, 336, 384, 432, 480 (including EOT if EOT is after Week 264) 
l 
Clinical chemistry (fasting): fasting glucose, total proteins, calcium, sodium, potassium, Lactate Dehydrogenase, (LDH), urea nitrogen and creatinine.  Creatinine clearance will be calculated during the study if 
clinical indicated.  
m Deleted. 
n ANA titer will be done at V1/V2 ( ie the last treatment visit from the initial study),  at Week 48, 96,  144, 192, 240, 264, 288, 336, 384, 432, 480 and EOT visit , or sooner if clinical indicated (Anti-ds-DNA only if 
ANA titer is >1:160) 
o Dipstick urinalysis for:  specific gravity, pH, glucose, blood, ketones, proteins, bilirubin, urobilinogen, nitrite, leukocytes. If any parameter is abnormal, a urinalysis sample should be sent to central laboratory for 
testing. If positive for proteins, microscopic analysis will be performed by central laboratory.  
p After Visit 7 (Week 12) between study visits the patient will have a urine pregnancy test at home on a monthly basis.  Patients will be given sufficient urine pregnancy kits to take home at each successive visit 
for monthly testing up until the final treatment visit. When the testing coincides with a clinical visit as indicated in the flow chart, the results should be reported in the e-CRF. No pregnancy test kits will be 
dispensed at EOT. 
q ECG to be done at Weeks 48, 96, 144, 192, 240, 264 or EOT; No ECG will be done after Week 264 including EOT if EOT is after Week 264  
r 
Rheumatoid factor only at Weeks 48, 96, 144, 192, 240, 264 or EOT; No Rheumatoid factor will be assessed after Week 264 including EOT if EOT is after Week 264 
s If throughout the study a serious adverse event (SAE) occurs in a patient, blood samples should be collected for sarilumab at or near the onset and completion of the occurrence of the event, if possible.  The 
exact date of sample collection and last dose must be recorded on the eCRF.  
t 
Serum sample for biomarkers to be collected for all patients except EFC13752: at V1/V2 (ie, the last treatment visit from the initial study), as well as Week 2, Week 12, and Week 48. 
u Blood sample for RNA except for SFY13370 and EFC13752 patients: to be collected at V1/V2 (Week 0) (baseline prior to administration of study drug) and V3 (Week 2) at site visit only (cancel RNA collection if 
home visit).  
v Deleted 
w Samples for IL-6 to be collected at V1/V2 for EFC11072 patients only (ie the last treatment visit) and for all patients at V4 (Week 4), V7 (Week 12), V8 (Week 24), V9 (Week 36), and V10 (Week 48).

INTRODUCTION AND RATIONALE 
Rheumatoid arthritis (RA) is a chronic, debilitating disease that primarily affects the synovial 
membrane of diarthrodial joints. 
Currently, treatment of RA involves the use of nonsteroidal anti-inflammatory drugs (NSAIDs), 
glucocorticoids and disease modifying anti-rheumatic drugs (DMARDs). Methotrexate, 
sulfasalazine, hydroxychloroquine and leflunomide are DMARDs that have been used by 
rheumatologists for many years (1)(2)(3). 
Introduction of biologic agents, especially inhibitors of TNF-α, has greatly improved the 
therapeutic options available for treating RA (4)(5)(6)(7)(8)(9); however, no therapeutic modality 
provides either universal or complete control of disease and safety remains one of the key issues 
with anti-TNF-α treatment (10)(11). 
Besides early benefit/risk of biologics, the long term outcome of RA remain a critical question: 
long term use of biologics have been associated with immunosuppression and effects on the 
development of infections, malignancies, demyelinating events, lupus like events, etc.  
Consequently, long-term data are needed to investigate the risks associated with the long-term use 
of these drugs. 
This LTS11210 study is intended to identify potential late onset adverse events associated with 
long-term use of sarilumab with or without concomitant non-biologic DMARD(s), including 
MTX, as well as to assess long-term efficacy. 
4.1 
SARILUMAB 
Sarilumab is a fully human immunoglobulin (Ig) G1 monoclonal antibody directed against the IL-
6Rα receptor produced using VelocImmune® technology developed by Regeneron. Sarilumab 
blocks the IL6 receptor and inhibits IL-6 signaling. Sarilumab is under development for the 
treatment of patients with moderate to severe RA. 
Sarilumab is a covalent heterotetramer consisting of two, disulfide linked human heavy chains, 
each covalently linked through disulfide bonds to a fully human kappa light chain. The antibody 
possesses a protein molecular weight of approximately 155 kDa, with a single N-linked 
glycosylation site in each heavy chain, located within the constant region in the Fc portion of the 
molecule.  The sarilumab heavy chain has an IgG1 isotype constant region (an allotype). The 
variable domains of the heavy and light chains combine to form the IL-6Rα binding site within 
the antibody.

See the Clinical Investigator’s Brochure for detailed information. 
Prior to entering LTS11210 patients were included in ACT11575, EFC11072, EFC10832, 
SFY13370, or EFC13752.   
In the initial studies patients were exposed to IMP for: 
• 12 weeks if they were initially randomized in EFC11072 Part A or ACT11575;  
• between 2 and 52 weeks, if initially randomized in EFC11072 Part B;  
• between 12 and 24 weeks, if initially randomized in EFC10832;  
• 24 weeks, if initially randomized in SFY13370 or EFC13752. 
These studies are described briefly below: 
EFC11072:  A randomized, double-blind, placebo-controlled, multi-centre, two-part, dose 
ranging (Part A) and confirmatory (Part B) study with an operationally seamless design, 
evaluating efficacy and safety of sarilumab added to methotrexate (MTX) in patients with active 
rheumatoid arthritis who are inadequate responders to MTX therapy. The study is completed.  
In the dose ranging part of the study (Part A), five doses (100 mg weekly [qw], 150 mg qw, 
100 mg every other week [q2w], 150 mg q2w, and 200 mg q2w) and placebo were tested in 
combination with methotrexate (MTX).  Two doses (150 mg every two weeks [q2w] and 200 mg 
q2w) were selected for the pivotal phase 3 studies. In the Phase 3 confirmatory part (Part B) both 
sarillumab arms showed clinically relevant and statistically significant (p<0.0001) improvements 
compared with placebo in all 3 co-primary efficacy endpoints (signs and symptoms [American 
College of Rheumatology criteria, ACR20], physical function [Health Assessment Questionnaire 
Disability Index, HAQ-DI], and radiographic progression [modified van der Heijde total Sharp 
score, vdH-mTSS]).  In this study, the safety profile was consistent with previous studies showing 
higher incidence of infections including serious infections, in the sarilumab treated groups 
compared to placebo, along with the expected laboratory data: a decrease in neutrophil count, 
elevated alanine aminotransferase, elevated serum LDL-cholesterol and injection site reactions 
(i.e., erythema, pruritus and rash). The incidence of treatment emergent anti-drug antibody (ADA) 
in the sarilumab 150 mg q2w, 200 mg q2w, and placebo groups were 19.8%, 14.6%, and 4.2%, 
with 3.5%, 2.4% and 0.2% of neutralizing ADA, respectively.  No notable differences have been 
observed with regards to loss or lack of efficacy or hypersensitivity reactions, including systemic 
and local, between those patients who were ADA positive and ADA negative (see the Investigator’s 
Brochure for details). 
ACT11575:  A randomized, double-blind, parallel-group, placebo- and active calibrator-
controlled study assessing the clinical benefit of sarilumab on top of MTX in patients with active 
RA who have failed previous TNF-α antagonists was terminated by the Sponsor due to 
administrative reasons with only 16 patients enrolled.

The objective of ACT11575 was to demonstrate that sarilumab added to MTX is superior in 
efficacy to placebo, for the relief of signs and symptoms of RA, in patients with active RA who 
have failed up to 2 TNF-α antagonists.  
EFC10832: A randomized, double-blind, parallel-group, placebo-controlled study assessing the 
efficacy and safety of sarilumab added to DMARD therapy in patients with active rheumatoid 
arthritis (RA) who are inadequate responders or intolerant to tumor necrosis factor-alpha (TNF-α) 
antagonists. The study is completed. 
The objective of EFC10832 was to demonstrate that sarilumab added to DMARD therapy is 
superior in efficacy to placebo for the relief of signs and symptoms of RA at Week 24 in patients 
with active RA who are inadequate responders or intolerant to TNF-α antagonists. 
SFY13370:  A randomized, double-blind, double-dummy study assessing the safety and 
tolerability of sarilumab and tocilizumab in patients with rheumatoid arthritis who are inadequate 
responders to or intolerant of TNF antagonists. The study is completed. 
The primary objective of SFY13370 was to assess, in the same study, the safety of sarilumab and 
tocilizumab in patients with rheumatoid arthritis (RA) who are inadequate responders to or 
intolerant of tumor necrosis factor (TNF) antagonists. 
EFC13752: An open-label, randomized, parallel group study assessing the immunogenicity and 
safety of sarilumab administered as monotherapy in patients with active rheumatoid arthritis. The 
study is completed. 
The primary objective was to evaluate the immunogenicity of sarilumab administered as 
monotherapy.

STUDY DESIGN 
6.1 
DESCRIPTION OF THE PROTOCOL 
This is a multicenter, multinational open label long term study, for patients with RA who 
participated and completed EFC11072, ACT11575, EFC10832, SFY13370, EFC13752 studies or 
for patients from 12 weeks onward with per protocol defined lack of efficacy from EFC10832. 
Patients, who were randomized in Part B of the study EFC11072 in a treatment arm subsequently 
not retained following pivotal dose selection, were also eligible for enrollment.  
Initially in LTS11210, patients received 150 mg of sarilumab SC weekly as the highest dose 
studied in EFC11072 Part A. The reduced dose (due to neutropenia, thrombocytopenia, or an 
increase in liver enzymes (ALT)), was 150 mg q2w.  Once the dose regimens were selected for 
the Phase 3 studies (150 mg q2w and 200 mg q2w), patients already ongoing in the study at the 
highest dose were switched to the new highest sarilumab dose 200 mg q2w, as soon as permitted 
by administrative process.  Patients previously assigned to the reduced dose of 150 mg q2w 
because of a safety issue continued to receive 150 mg q2w. 
6.2 
DURATION OF STUDY PARTICIPATION 
The IMP will be administered for 264 weeks from the first IMP administration in LTS11210. In 
addition the patients will continue to be treated beyond 264 weeks until sarilumab is commercially 
available in their country or until 2020 at the latest when the study will be closed. (In the UK the 
duration of treatment will be 264 weeks from the first study drug administration in LTS11210). 
The total maximum duration of study participation for a patient may be up to 523 weeks.  
• 1-week screening period if applicable  
• 516-week maximum treatment period in LTS11210 (for the earliest patients enrolled in 
LTS11210 in 2010 if sarilumab is not commercialized by 2020)  
• 6-week follow up period as required per protocol 
Further explanation is given below and in Section 12.1. 
Patients will either enter a 1-week screening period (patients from EFC11072 Part A or Part B1 
and ACT11575), or enrol directly into the treatment period (for patients from EFC11072 Part B2, 
EFC10832, SFY13370, or EFC13752 the EOT visit in the initial study corresponds to the 
randomization visit in the LTS11210 study).  
The duration of the treatment period in the study will be at least 264 weeks, or up to a maximum 
of 516 weeks (except in the UK where the duration of treatment will be 264 weeks).  
Patients will return for the safety follow-up visit 6 weeks after the EOT visit. In case of early 
treatment discontinuation, patients are required to complete the EOT visit and to return for the

6-week safety follow-up visit as well. In patients who complete sarilumab treatment per protocol 
in countries where sarilumab is commercially available the post treatment follow-up visit may be 
cancelled if the patient initiates treatment with commercial sarilumab during the post treatment 
follow-up period. However, in this case, a telephone contact must be established with the patient 
to capture all AEs occurring up to the 1st administration of commercial sarilumab. 
The study will be considered completed for a patient at the time he/she completes all the 
scheduled procedures as described in Section 12.1. 
6.3 
OPTIONAL PFS-S SUB-STUDY 
An optional 12-week sub-study aiming to evaluate the usability of pre-filled syringe with safety 
system (PFS-S) will be conducted in some countries. Patients enrolled in LTS11210 at selected 
sites in those countries may participate in the PFS-S sub-study from Week 24 of the main study 
after providing written informed consent for the sub-study. However, patients may continue to 
participate in the main trial without participating in the PFS-S sub-study if they wish. Full details 
of the PFS-S sub-study are presented in Appendix R. 
6.4 
STUDY COMMITTEES 
6.4.1 Data Monitoring Committee 
A Data Monitoring Committee (DMC) is in place for the sarilumab clinical study program. The 
sarilumab DMC monitors the safety of the patients participating in all ongoing sarilumab studies.  
The DMC is responsible for giving appropriate recommendations to the Sponsor on safety aspects 
during the conduct of the study, if needed.  In addition to the review of serious adverse events 
with fatal outcome and specific adverse events, the DMC has access to complementary safety 
parameters (eg, vital signs, laboratory test results etc.) and access to limited efficacy data.  The 
DMC responsibilities and the data review processes are fully described in the sarilumab DMC 
charter. 
Members of the DMC will be independent of those performing the study, being neither 
investigators nor employees of the Sponsor; and without conflict of interest regarding study 
outcome (whatever they are). 
6.4.2 Cardiovascular Adjudication Committee 
An independent Cardiovascular Adjudication Committee (CAC) has been established for the 
sarilumab clinical study program.  The role of the CAC is to apply uniform criteria for the 
evaluation of cardiovascular events (including retrospective events), and to adjudicate these 
events in a consistent and unbiased manner throughout the course of the study.  The goal of the 
CAC is to ensure that cardiovascular events reported by the site are judged uniformly, using the 
same criteria by a group of experts in cardiology and neurology, independent from Sanofi. The 
CAC will be blinded to treatment allocation.  The CAC responsibilities, detailed definitions of

STUDY TREATMENTS 
8.1 
INVESTIGATIONAL MEDICINAL PRODUCT 
• 
Pharmaceutical form: the pharmaceutical form of sarilumab has been modified since the 
initial version of the study protocol. Sarilumab, in vials (formulation C1F2), was 
dispensed to all patients enrolled into the study prior to the phase 3 dose selection 
decision. Thereafter, drug product in vials has been phased out of the study, and patients 
have been dispensed with drug product in prefilled syringes (pivotal formulation C2F3) 
once sufficient quantities were available and appropriate local approvals obtained. For 
completeness, all IMP formats used during the study are presented here: 
- 
Currently dispensed IMP for all patients:  
- 
Sarilumab in prefilled syringe (PFS): Glass syringes with a 27 gauge thin wall, 
1/2-inch staked needle, with FM30 needle tip cap (latex free) filled at 1.14 mL with 
C2F3 drug product at 131.6 mg/mL (150mg dose) or 175 mg/mL (200mg dose). 
PFS with FM30 needle tip is the only pharmaceutical form dispensed to patients 
from EFC10832, SFY13370, and EFC13752. 
- 
Sarilumab in prefilled syringe with safety system (PFS-S) with exactly the 
same formulation as the PFS with FM30 needle tip cap described above. The 
PFS-S is used for patients in the sub-study only. Refer to Appendix R for 
further details of the safety system. 
- 
Previously dispensed IMP: 
- 
Sarilumab in amber glass vials: filled to 2 mL with 75 mg/mL (150mg dose), or 
100 mg/mL (200mg dose) of C1F2 drug product 
- 
Sarilumab in PFS: Glass syringes as described above, but with FM27 rubber needle 
shield (needle cap may contain dry natural rubber latex)   
To ensure that the administration of the investigational product with PFS will minimally 
deliver the targeted doses of 150 mg and 200 mg, the PFS will contain an 8% average 
overfill.  
• Dose per administration 
Before the phase 3 pivotal dose regimens were selected: 
- 
150 mg administered weekly or every other week (reduced dose) 
After the phase 3 pivotal dose regimens were selected:  
- 
200 mg administered every other week or 150 mg administered every other week 
(reduced dose).  
• Route and method of administration:  Subcutaneously in abdomen, thigh or upper arm.

Each drug administration requires one single injection.  It is preferred that subcutaneous 
injection sites be rotated between the four quadrants of the abdomen (except the navel or 
waist area) or the thigh (front and side).  If needed, SC injection can be administered by a 
caregiver in the upper arm (lateral side). 
Subjects and/or their non-professional caregivers will be trained to prepare and administer 
study drug at the start of the double blind-treatment period of the previous study.  This 
training must be documented in the subject’s study file.  The study staff should review the 
subject’s self-administration technique at Visit 2 or V1/V2 (Week 0) for the LTS11210 
study.  For doses not given at the study site, diaries will be provided to record information 
pertaining to those injections.  If the subject is unable or unwilling to administer study 
drug, arrangements must be made for a qualified site personnel or a caregiver to 
administer study drug doses that are not scheduled to be given at the study site. 
The IMP administration should be taken strictly every 14 days as per protocol IMP 
administration schedule, however an IMP administration time window of ±3 days is 
permitted in exceptional circumstances (eg, the result of a repeat CBC test is not available, 
or an ongoing adverse event). For the subsequent IMP administration the initial IMP 
administration schedule should be followed again.  
Note: an interval of at least 11 days between 2 IMP doses must be maintained. 
8.2 
NON INVESTIGATIONAL PRODUCTS 
For patients rolling over from EFC11072, ACT11575, EFC10832, and SFY13370: 
All patients should continue to receive the non-biologic DMARD(s) background therapy that they 
were receiving in the initial study until the end of study treatment. However, at any time the 
DMARD(s) dose can be reduced, temporarily or permanently discontinued, or a patient may 
switch to alternate approved non-biologic DMARD for safety or tolerability reasons. If the new 
DMARD is initiated the dosing as well as safety monitoring should follow the applicable local 
labeling information. 
Each non-biologic DMARD will be recorded throughout the study on the e-CRF.  Any change 
should be recorded on the e-CRF.  DMARD(s) will not be dispensed or supplied by the Sponsor 
as an investigational product. 
All patients receiving MTX as their background DMARD will also receive folic/folinic acid 
(5 mg weekly or greater) according to local guidelines in the country where the study is 
conducted. 
For patients rolling over from EFC13752: 
Treatment with non-biologic DMARDs is not allowed. All patients should continue with 
sarilumab monotherapy until the end of study treatment. The IMP should be permanently 
discontinued if any DMARD is initiated.

METHOD OF ASSIGNING PATIENTS TO TREATMENT GROUP 
This is an open-label study and every patient will receive sarilumab. Treatment kit numbers will 
be allocated via interactive voice/web response system (IVRS/IWRS). Patients will keep the same 
identification number that they were allocated in the previous study. 
8.5 
PACKAGING AND LABELING 
The investigational products will be supplied in treatment kit boxes that are labeled in accordance 
with the local regulatory specifications and requirements and content information, dosing 
instructions and precautionary statement (“for clinical use only”). 
The number of treatment kits allocated to the patient will provide sufficient medication until the 
next clinic visit. An additional treatment kit, to provide medication to randomized patients in 
circumstances, e.g., a damaged kit, will be allocated by IVRS if a “replacement call” is made to 
the IVRS system. 
Each IMP unit will be labeled in accordance with the local regulatory requirement. 
8.6 
STORAGE CONDITIONS AND SHELF LIFE 
All investigational drug supplies must be kept refrigerated in appropriate, secure area (for 
example, a locked cabinet or a locked room) under the responsibility of the Investigator or other 
authorized individual and must be stored separately from other medication and in the original 
carton as per specification mentioned on the label.  
8.7 
RESPONSIBILITIES 
The Investigator, the Hospital Pharmacist, or other personnel allowed to store and dispense 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 the applicable regulatory requirements. 
All IMP shall 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.

8.7.1 Access to the randomization code during the study 
This section is not applicable for the study. 
However, in the case of a medically urgent situation, and if the Investigator (first contact person) 
cannot be reached, a competent medical professional can call a 24-hour emergency number 
provided by the Sponsor in order to get further information on the study or for medical questions. 
8.8 
CONCOMITANT MEDICATION 
A concomitant medication is any treatment received by the patient at the same time as any 
IMP(s). All medication taken during the study should be recorded on the corresponding pages of 
the e-CRF including any change in dose. 
8.8.1 Prohibited concomitant medication 
• Use of any biologic treatment for RA is not authorized during the study until 6 weeks 
following the EOT visit. If any of these treatments are used, the study treatment should be 
permanently discontinued. 
• Treatment with non-biologic DMARD(s) (such as cyclosporine, sulfasalazine, 
hydroxychloroquine, or cyclophosphamide) other than the DMARD(s) received in the 
initial study (ie, study immediately preceding LTS11210 enrollment) is not permitted until 
the end of treatment unless a change to an alternate approved non-biologic DMARD is 
made for safety or tolerability reasons. If the new DMARD is initiated the dosing as well 
as safety monitoring should follow local labeling information. For EFC13752 patients, the 
treatment with non-biologic DMARD(s) is not authorized until the end of the treatment. 
See Section 8.2 for additional details. 
• Treatment with tofacitinib or any other JAK inhibitor is not authorized during the course 
of the study. If any of these treatments are used, the patient should be discontinued. 
• Administration of any live (attenuated) vaccine is contraindicated (see list in Appendix K) 
until 3 months following the last study drug administration. 
• Treatment with any investigational medicinal product other than sarilumab is not 
permitted.

8.8.2 Permitted concomitant medication 
• Steroids 
- 
Oral corticosteroids are permitted to be taken at the time of study entry at the dose of 
≤ 10 mg prednisone or equivalent. 
- 
Intranasal or inhaled corticosteroids are authorized as needed throughout the study. 
- 
At any time the corticosteroid dose can be modified, temporarily or permanently 
discontinued, or a new steroid initiated (irrespective of the mode of administration), for 
any reason per investigator judgment including but not limited to worsening of RA, 
treatment of AEs or for the prevention of corticosteroid associated side effects.  
• Nonsteroidal anti-inflammatory drugs and analgesics: 
- 
Non-steroidal inflammatory drugs (NSAIDs) and cyclo-oxygenase-2 inhibitors (COX-
2) are permitted as needed throughout the study. The dose used should be in 
accordance with the approved dose in the country in which the study is conducted.  
- 
Narcotic or non-narcotic analgesics (with no anti-inflammatory properties) for RA pain 
relief are permitted based on investigator judgment that there is insufficient RA pain 
relief with stable maintenance NSAIDs. As limited treatment for inter-current pain, all 
analgesics (with no anti-inflammatory properties) are allowed. These analgesics, 
including acetaminophen, should be avoided within 6 hours of efficacy assessments, 
including physical function and quality of life assessments. 
- 
Acetaminophen use should be limited to 4g/24h. Specific attention should be paid to 
co-administration of hepatotoxic drugs (see specific Section 10.2.4).   
• Cytochrome P450 enzyme substrates 
IL6 has been shown to reduce CYP1A2, CYP2C9, CYP2C19 and CYP3A4 enzyme 
expression in in-vitro studies. Therefore, when IL-6 is blocked using sarilumab IL-6 levels 
“normalize” and CYP450 enzymes may increase which could result in dose adjustment for 
drugs that are metabolized by CYP450 enzymes. As a precautionary measure, drugs which 
are metabolized via these cytochromes and with a narrow therapeutic index should be 
adjusted if needed: dose to be increased to maintain efficacy after initiation of sarilumab 
and to be decreased after sarilumab is stopped. Some examples of CYP450 substrates with 
a narrow therapeutic index, requiring monitoring of effect are warfarin or monitoring of 
drug concentration include cyclosporine, theophylline, digoxin, antiepileptics, such as 
carbamazepine (Carbatrol®, Tegretol®), divalproex (Depakote®), phenytoin (Dilantin®), 
or valproic acid (Depakene®); or antiarrhythmics, such as disopyramide (Norpace®), 
procainamide (Procan®, Pronestyl®), or quinidine (Quinidex®, Quin-Release Quin-G®). 
• Lipid lowering drugs: 
Lipid lowering drugs are permitted. Anti-IL-6 drugs, including sarilumab are known to 
increase serum cholesterol levels and this effect will be closely monitored during the 
study.  If, during the study, patients are found to have significant increase in cholesterol 
levels, then cholesterol lowering therapy per National Cholesterol Education program

(NCEP)Adult Treatment Panel (ATP)3 (NCEP/ATP3) or  local guidelines should be 
initiated or the dose of concomitant lipid lowering drug(s) adjusted.  A referral to a 
specialist should be considered when dyslipidemia is difficult to manage. 
8.9 
CONCOMITANT TREATMENT 
A concomitant treatment is any treatment received by the patient, at the same time as the IMP(s), 
other than medications. Treatments received during the study should be recorded on the 
corresponding pages of the patient’s e-CRF as appropriate. 
Joint replacement is permitted during the study. The IMP should be temporarily interrupted prior 
to surgery as per applicable guidelines and the IMP restarted as soon as proper wound healing is 
established.  
NOTE: The IMP can be temporarily discontinued for ≤59 days (3 IMP doses can be missed). If 
the re-initiation of the IMP occurs later than 38 days since the last IMP dose (2 IMP doses were 
already missed), the IMP has to be administered at the study site and the patient to be observed for 
30 minutes for any medical events. 
8.10 
TREATMENT ACCOUNTABILITY AND COMPLIANCE 
Measures taken to ensure and document treatment compliance and investigational medicinal 
product accountability include: 
• Proper recording of medication treatment pack number on appropriate e-CRF page for 
accounting purposes. 
• All medication treatment kits (containing vials, or prefilled syringes, whether empty or 
unused study medication) are returned by the patient at each visit.  
- 
As the used prefilled syringes cannot be safely returned to the study site after 
administration of IMP, the completed patient injection diary (returned to the site at 
each visit), returned treatment kit boxes and any unused prefilled syringes will be used 
for drug accountability purposes. 
• The study coordinator tracks treatment accountability/compliance, either by diary, or by 
counting the number of empty IMP containers (vials or prefilled syringes), and fills in the 
appropriate page of the patient treatment log. 
• The monitor in charge of the study then checks the data entered on the investigational 
medicinal product administration page by comparing them with the investigational 
medicinal product which has been retrieved and the patient treatment log form.

ASSESSMENT OF INVESTIGATIONAL PRODUCT 
9.1 
ENDPOINTS 
9.1.1 Primary endpoint 
Incidence of adverse events: (see Section 10.1) 
9.1.2 Secondary endpoints 
The secondary endpoints will be: 
• The proportion of patients at week 12 and over time who achieve ACR20/ACR50/ACR70, 
DAS28 Remission, and EULAR Response. 
• DAS28-CRP over time 
• HAQ-DI results over time.   
• Van der Heijde modified total Sharp score over time and incidence of radiographic 
progression of the van der Heijde modified total sharp score for the subset of patients who 
previously completed the study EFC11072 Part B.  
• Each component of the ACR over time. 
• Health economic endpoints and Patient reported outcomes: patients will continue in 
evaluation of the health economic endpoints as per the initial study. 
9.1.2.1 ACR20/ACR50/ACR70 
Signs and symptoms are assessed with a composite rating scale of the ACR (American College of 
Rheumatology) that includes 7 variables: 
- 
Tender Joints Count (TJC) 
- 
Swollen Joints Count (SJC) 
- 
Levels of an acute phase reactant (CRP level) 
- 
Patient’s assessment of pain 
- 
Patient’s global assessment of disease activity 
- 
Physician’s global assessment of disease activity 
- 
Patient’s assessment of physical function 
The details of the ACR score are presented in Appendix B.

Page 49 
ACR20 is defined as the percentage of patients who achieve at least 20% improvement in both 
tender joint count and swollen joint count and, at least 20% improvement in at least 3 of the 5 
other assessments. 
ACR50 is defined as the percentage of patients who achieve at least 50% improvement in both 
tender joint count and swollen joint count and, at least 50% improvement in at least 3 of the 5 
other assessments. 
ACR70 is defined as the percentage of patients who achieve at least 70% improvement in both 
tender joint count and swollen joint count and, at least 70% improvement in at least 3 of the 5 
other assessments. 
ACR scores will only be assessed up to Week 264 at the time points as per study flowchart. 
9.1.2.2 DAS28-CRP  
Disease activity state will be measured and presented using the disease activity score (DAS28).  In 
this protocol, unless otherwise specified, DAS28 refers to DAS28-CRP.  DAS28 is a composite 
score that includes 4 variables: 
• 
Tender Joints Count (based on 28 joints - see Appendix B) 
• 
Swollen Joints Count (based on 28 joints - see Appendix B) 
• 
General health assessment (GH) by the patient assessed from the ACR RA core set 
questionnaire (patient global assessment) 
• 
Marker of inflammation assessed by the hs-CRP. 
It is a continuous measure allowing for measurement of absolute change in disease burden and 
percentage improvement.  It has been extensively validated for its use in clinical trials and 
accepted by Health Authorities.  The DAS28 can be calculated using the following formula: 
DAS28 = 0.56 x 
TJC
28
 + 0.28 x  
SJC
28
 + 0.36 x Log(CRP+1) + 0.014 x GH + 0.96 
The DAS28 provides a number indicating the current activity of the RA.  A DAS28 above 5.1 
means high disease activity, whereas a DAS28 below 3.2 indicates low disease activity and a 
DAS28 below 2.6 means disease remission.  
9.1.2.3 EULAR response 
Improvement in disease activity will also be assessed using the EULAR response criteria: 
• 
Good response = DAS28 improvement of >1.2 and a present DAS28 score ≤3.2 
• 
Moderate response = DAS28 improvement of >0.6 to ≤1.2 and a present DAS28 score 
≤5.1, or an improvement >1.2 and a present score >3.2 
• 
Nonresponse = DAS28 improvement of ≤0.6, or an improvement >0.6 to ≤1.2 and a 
present DAS28 score >5.1

9.1.2.4 Van der Heijde modified Total Sharp Score 
The van der Heijde modified Sharp method is a composite X-ray scoring system used to assess 
structural (joint) disease progression in RA (see Appendix C). The method evaluates both joint 
erosions (JE) and joint space narrowing (JSN) in bilateral hand and foot joints. 
The change from baseline in van der Heijde modified total Sharp score will be evaluated for 
patients who completed the EFC11072 Part B study in order to demonstrate maintenance of 
sarilumab effect on joints.  It will be assessed at week 48, 96, 144 and 192, or at the end of 
treatment for patients who prematurely discontinue from the study before Week 192. 
NOTE: the sponsor will not perform any medical evaluation on collected X-rays. They will be 
blindly assessed by independent graders and modified Van Der Heijde Total Sharp Score will be 
calculated per patient per visit. 
9.1.2.5 Physical Function 
Improvement in physical function is assessed by the change from baseline (original study) in 
HAQ-DI at week 48, 96, 144, 192, 240, 264, and EOT, if EOT is prior to Week 264.  It is based 
on the HAQ-DI assessment that is completed at each visit by the patient, as one of the ACR 
components. 
The HAQ-DI is composed of 8 categories as follows: dressing and grooming, arising, eating, 
walking, hygiene, reach, grip and activities, for which there are at least 2 questions by category. 
The patient will be asked to score how difficult he/she feels it is to perform such activities using a 
0 to 3 scoring (0=without any difficulty, 1=with some difficulty, 2=with much difficulty and 
3=unable to do). If the patient is using assistance for any of these activities, scoring may be 
adjusted.  For each category, the highest score given for one of the question is attributed to the 
category.  The total score is the sum of all categories’ scores divided by the number of answered 
categories (at least 3 categories should be answered) (see Appendix J). 
9.1.2.6 ACR Components 
Each component of the ACR will be analysed as other secondary outcomes over time.  
All ACR components will be assessed up to Week 264.  
After Week 264, TJC and SJC (both based on 28 joints), patient´s global assessment of disease 
activity and hs-CRP will still be assessed to calculate DAS28. 
9.1.2.7 Health economic assessment and Patient reported outcomes (PROs)  
• Health economic assessments and PROs will be performed up to Week 264 as defined in 
the initial study and as specified in the study flowchart (See section 1.2).

• The Functional Assessment of Chronic Illness Therapy Fatigue scale (FACIT-Fatigue) 
will be used to assess fatigue. The FACIT-Fatigue is a 13-item questionnaire rated 0 to 4 
originally developed to measure fatigue in patients with cancer and widely used in 
rheumatoid arthritis patients that demonstrates good consistency and sensitivity to change. 
The patient will be asked to answer 13 questions rated 0 to 4 (0 = not at all, 1 = a little bit, 
2 = some what, 3 = quite a bit, 4 = very much) (see Appendix F). The patient will be asked 
to fill in the questionnaire at different site visits (see flow chart, Section 1.2) 
• The Work Productivity and Activities Impairment (WPAI) will be assessed for patients 
coming from EFC11072 and ACT11575 only.  The WPAI was developed by Margaret 
Reilly for assessing productivity losses by measuring the effect of general health and 
symptom severity on work as well as usual activity productivity.  Specific-disease WPAI 
exists and can be adapted to different pathologies.  The RA WPAI (Appendix G): 
instrument consists of 6 questions that ask the subject the number of hours missed from 
work (ie, absenteeism) due to RA, the number of hours missed from work for anything 
other than RA, the number of hours totally worked, as well as how much the RA does 
affect the productivity at work or the ability to do daily activities over the past 7 days. The 
instrument can be self-, interview-, or telephone-administered and takes less than 5 
minutes to complete (~3 minutes). The 4 scores of the questionnaire are expressed as 
impairment percentages with higher numbers reflecting greater impairment and decreased 
productivity. The 4 scores are: 
1. Percent work time missed due to RA 
2. Percent impairment while working due to RA 
3. Percent overall work impairment due to RA 
4. Percent activity impairment due to RA 
• The WPAI has been tested in many disease states including migraine, arthritis, 
hypertension, diabetes, and depression and is adaptable to specific health problems such as 
RA. Inclusion of this measure in the study assesses the impact of sarilumab on a major 
component of subjects’ lives, which is their ability to perform daily activities and/or be 
able to work. The patient will be asked to fill in the questionnaire at different site visits 
(see flow chart, Section 1.2) 
• Assessment of joint replacement and joint procedures if any will be performed: total joint 
replacement (arthroplasty). 
• Sleep: Rheumatoid arthritis, like other chronic illness, is associated with sleep 
disturbances. Sleep disturbance is linked to pain, mood, and disease activity. The effect of 
sarilumab on pain will be assessed on a VAS scale (see Appendix H). The patient will be 
asked to fill in the questionnaire at different site visits (see flow chart, Section 1.2) 
• SF-36: The Short-Form 36 (SF-36) is a generic questionnaire measuring general health 
status (quality of life). It is one of the most frequently used and has been extensively 
validated in rheumatologic disease (see Appendix I ). The patient will be asked to fill in 
the questionnaire at different site visits (see flow chart, Section 1.2)

• The Rheumatoid Arthritis-Work Productivity Survey (WPS-RA): The WPS-RA is a 
validated questionnaire that evaluates productivity limitations within work and within 
home associated with RA over the previous month. 
It is interviewer-administered, is based on patient self-report.  It contains 8 items that 
include 3 work productivity related items and 5 home productivities related items 
(household activities) (see Section 27, Appendix Q) plus 1 item related to the employment 
status.

9.3.1 Sampling time 
Serum samples will be collected for determination of functional sarilumab, anti-sarilumab 
antibody (also known as anti-drug antibody (ADA)) and IL-6 according to the Study Flow Chart 
(Section 1.2).  The date of collection should be recorded in the e-CRF. 
Serum concentrations of bound (serum sarilumab-sIL-6Rα complex) and functional sarilumab 
were intended to be analyzed in the study. After the completion of EFC11072 Part B study, the 
Sponsor made the decision to only analyze functional sarilumab concentrations. 
If a serious adverse event (SAE) occurs in a patient, serum samples should be collected for 
determination of sarilumab at or near the onset and completion of the occurrence of the event, if 
possible.  The exact date of sample collection and last dose must be recorded on the e-CRF.

Potential studies may include examining markers related to IL-6 signaling, response to sarilumab, 
or related to the disease of RA. It is anticipated that the serum and RNA biomarker samples will 
be stored for up to 15 years (or as appropriate, according to applicable regulations) after 
completion of the final report of the main clinical trial. Storage after the end of the study will be at 
an accredited, dedicated long term biological sample storage facility which has established a strict 
and comprehensive security and confidentiality system. Samples will remain the property of the 
Sponsor and will be used only for the purposes described here, upon request by the Sponsor. 
9.4.1 Serum for future biomarker analysis 
A serum sample (5 ml) will be collected for future biomarker analysis at the EOT visit of the 
initial study, and at Week 2, Week 12, and Week 48 (except EFC13752 patients).  
9.4.2 RNA for future biomarker analysis 
Whole blood samples for ribonucleic acid (RNA) expression profiling (non-genetic analysis) will 
be collected at Week 0 (V2 or V1/V2), prior to treatment, and at Week 2/Visit 3 site visits only 
(except for SFY13370 and EFC13752 patients).  
If week 2/Visit 3 is scheduled as a “home visit”, the whole blood sample for RNA will not be

PATIENT SAFETY 
10.1 
SAFETY PARAMETERS ASSESSED IN THIS TRIAL 
• Adverse events: at every visit, the Investigator will ask the patient how he has felt since 
the last study visit. 
• Vital signs: 
- 
Vital signs including temperature, blood pressure, and heart rate will be collected prior 
to dosing per specifications on the study flow chart (see Section 1.2): 
- 
Body temperature will be collected using the same method for a given patient. Any 
fever:  body temperature ≥ 38°C should be recorded as an adverse event and the 
Investigator should perform all investigations necessary to rule out infection (see 
Section 10.2). 
- 
Blood pressure will be measured under standardized conditions, using the same well 
calibrated apparatus.  Both systolic and diastolic blood pressure should be recorded.  
Supine or sitting blood pressure should be checked after 2 minutes of rest.  Standing 
blood pressure is obtained 1 minute after the patient stands up.  The same arm should 
be used to measure blood pressure throughout the study. 
• Physical examination: A complete physical examination including a neurological 
examination will be performed as specified in the flowchart (see Section 1.2).  Any 
clinically significant abnormalities should be reported in the patient e-CRF as an adverse 
event.  Body Weight should be taken on a regular basis per specifications on the study 
flow chart (see Section 1.2) 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. 
• Tuberculosis assessment:  (see Section 1.2 and Section 10.2) 
• Electrocardiogram (ECG):  A standard 12-lead ECG will be performed as specified in 
the flowchart (see Section 1.2). Heart rate, QRS duration, PR interval, QT interval, ST 
deviation, T-wave morphology, U wave presence or absence will be determined using a 
centralized automatic and manual reading of all ECG. 
• Laboratory safety:  Blood will be taken before study drug dosing at the study site or at 
home by qualified personal. The following laboratory tests will be performed per 
specifications on the study flow chart (see Section 1.2):

SAFETY INSTRUCTIONS 
10.2.1 Infections 
Biologics including TNF-α inhibitors and tocilizumab (another IL-6 receptor inhibitor similar to 
sarilumab) have been associated with an increased risk of infection, including black box warnings 
for serious infections leading to hospitalization or death. 
In the ongoing phase 3 program, serious infections including life threatening sepsis, have been 
reported, some notably associated with minor trauma. As a precautionary measure, investigators 
should carefully follow any signs of infection with particular care to identify potential infective 
complications in immune-suppressed individuals where superficial skin wounds or abrasions may 
lead to serious infections including necrotizing fasciitis and/or sepsis. 
Any infection should be reported by the Investigator as an adverse event and a corresponding 
e-CRF form should be filled in.  Treatment with antibiotics if any should be recorded with the 
route of administration. 
• Clinically significant infection: Section 10.5.4 defines clinically significant infections 
that require pre-specified monitoring and should be reported as adverse events of pre-
specified monitoring/adverse events of special interest (AEPM/AESIs) with immediate 
notification. In case of suspicion of clinically significant infection, a complete diagnosic 
work-up should be performed including but not limited to cultures for bacterial infections, 
fungi and/or mycobacteria, histopathological or cytological evaluation, antigen detection 
and serum antibody titers. The type of infection should be listed in the e-CRF form.  The 
patient should be referred to a specialist if needed for diagnosis and treatment.  In addition, 
the study Investigator should determine if the infection qualifies for serious adverse event 
reporting or not.  
• Note:  Systemic opportunistic infections should be reported as serious.  
- 
The IMP should be temporarily discontinued in case of infection requiring oral or 
parenteral treatment with antibacterial, antiviral and/or antifungal agents (See  
Section 11.1) or permanently discontinued in case of confirmed opportunistic 
infections including but not limited to TB. (See Section 11.2.1 and Appendix M).

Tuberculosis assessment:  Sarilumab is a biologic treatment that may induce 
immunosuppression, including the risk of reactivation of latent tuberculosis.  A special 
warning of the increased risk of tuberculosis is included in the labels of TNF antagonists 
and tocilizumab. 
As a precautionary measure, patients at risk for tuberculosis will be permanently 
discontinued from the study.  
A clinical examination and history will be performed at every visit to assess any signs and 
symptoms of tuberculosis or contact with a patient with active tuberculosis.

A QuantiFERON TB Gold test can be performed at any time during the course of the 
study in case of suspicion of tuberculosis.  A chest X-ray should be performed in all 
patients with suspected tuberculosis. 
In case of suspicion of TB, the Investigator should refer the patient to a specialist for a 
complete examination.  The study drug should be discontinued until TB is ruled out. 
Repeat chest radiographs should be performed as indicated by local treatment guidelines 
or practice for monitoring while on immunosuppressive/immunomodulatory therapy. If 
such guidelines are not available/ applicable, a chest X-rays should be performed when 
clinically indicated. 
10.2.2 Demyelinating / Neurological events 
Any demyelinating event or significant, unexplained neurological symptom should be considered 
as an adverse event with prespecified monitoring (see Section 10.5.4). Refer to Section 11.2 for 
demyelinating/neurological events requiring permanent treatment discontinuation. 
Rarely, biologics have been associated with Progressive Multifocal Leukoencephalopathy (PML).  
The investigator should check any signs that might be suggestive of a PML at every visit: such as, 
but not limited to, unusual weakness, loss of coordination, changes in vision, difficulty speaking 
and sometimes personality changes.  In case of suspicion of an event potentially related to a 
demyelinating event or significant, unexplained neurological symptom during the course of the 
study, the patient should be referred to a neurologist for a complete examination.   
10.2.3 Autoimmunity and Lupus-like syndrome 
Anti DNA antibodies: ANA (Antinuclear antibody) and Anti- double- stranded DNA (Anti- ds-
DNA) antibody will be performed to assess the effect of sarilumab to induce autoimmune 
disorders most specifically for Systemic Lupus Erythematosus (SLE).  Indeed, 
immunosuppressant agents such as TNF antagonists have been associated with induction of SLE 
and SLE like syndromes.  Anti-ds DNA antibody will be tested only if ANA is positive (≥1:160 
titer). 
The presence of either of these antibodies may be without clinical consequence or associated with 
a clinical syndrome.  Their significance will be determined on a by-patient basis. 
If a diagnosis of lupus-like syndrome is suspected, this should be reported as an AEPM/AESI (see 
Section 10.5.4). 
10.2.4 Liver Function 
Transient, generally mild, elevation of transaminases has been observed with sarilumab. See the 
Clinical Investigator’s Brochure (CIB). 
Moreover, the co-administration of MTX or NSAID may represent an additional risk factor for 
observing signs of hepatotoxicity which is reflected in the American College of Rheumatology 
(electronic

(ACR) guidelines (12). The investigator is recommended to monitor transaminases in any patient 
receiving MTX but without any defined threshold for transaminases to start reducing MTX 
dosage which is thus left to the investigator judgement. 
Please refer to Section 10.5.4 for LFT abnormalities to be reported as AEPM/AESI with or 
without immediate notification. 
The Sponsor relies on the Investigator´s judgement for adapting concomitant medication, 
including dose reduction of MTX dosage, in case of LFT abnormalities within the guidelines 
below. 
In the present protocol, in order to closely follow LFTs, assessment of ALT, AST, alkaline 
phosphatase, prothrombin time, albumin, total bilirubin, conjugated bilirubin and unconjugated 
bilirubin will be performed per specifications on the study flow chart (see Section 1.2). 
• 
The study drug should be permanently discontinued in case of confirmed ALT > 5 ULN or 
in case of confirmed ALT>3 ULN and concomitant total bilirubin >2 ULN (unless the 
patient has a documented Gilbert’s disease).  A complete serological and ultrasonography 
work-up should be conducted in case of ALT >5 ULN or ALT>3 ULN and concomitant 
bilirubin >2 ULN (see Appendix L). 
• 
If ALT ≥3 ULN and ≤5 ULN and bilirubin ≤2 ULN, administration of study drug must be 
temporarily interrupted, and the study Investigator should immediately contact the patient 
to arrange for repeat LFTs within 48 hours from the Investigator’s awareness of the 
abnormal LFT results: 
- 
IMP should be temporarily interrupted until the ALT is below <3 ULN then restarted 
at the dose of 150 mg q2w at the Investigator´s discretion. 
- 
LFTs should be repeated according to the provided guideline and at a minimum of 
every 7 days until conditions for resumption of IMP administration are met (see 
Appendix L).  
10.2.5 Neutrophils 
Refer to Section 10.5.4 criteria for reporting neutropenia as AEPM/AESI with or without 
immediate notification. 
For all patients, a CBC test must be performed a few days before or at Visit 3, but not earlier than 
the 12th day after the first dose of IMP administration (using either designated central lab or local 
laboratory facility), and results reviewed prior to the administration of the 2nd dose of study drug 
in order to confirm that the neutrophil count is not within the protocol-defined limits for 
temporary, or permanent discontinuation of study drug. 
For all subsequent visits, in order to prevent the administration of study drug in patients at risk for 
severe neutropenia, whenever the neutrophil count is ≥ 1000/mm3 but less than the lower limit of 
normal (LLN) based on designated central laboratory test specifications, the CBC test (with 
differential) must be repeated to confirm that the neutrophil count is not within the protocol-

defined limits for temporary, or permanent discontinuation of study drug, before the next 
administration of study drug. The outlined procedures below will be followed: 
• 
Contact patient as soon as possible and schedule “repeat CBC blood test”; the repeat blood 
test can be arranged using the designated central lab or a local laboratory facility. 
• 
If the results of the “repeat CBC blood test” (either designated central lab or local 
laboratory facility results) confirm that the neutrophil count is ≥ 1000/mm3 (1.0 GI/L), the 
study drug may be administered. 
• 
If the results of the “repeat CBC blood test” (either designated central lab or local 
laboratory facility results) demonstrate that the neutrophil count is < 1000/mm3 (1.0 GI/L), 
the study drug must be temporarily or permanently discontinued, per protocol stopping 
rules defined below, and in Appendix L. 
• 
Note:  All per protocol-scheduled CBC tests must be performed using the designated 
central lab, even in circumstances when a local laboratory facility is also used to determine 
the neutrophil count before dosing. 
In case of a decrease in the neutrophil count to a level ≥ 500/mm3 and < 1000/mm3: 
• 
Study drug must be temporarily discontinued; the patient must be assessed for evidence of 
infection and CBC blood test repeated within 48 hours from the study Investigator’s 
awareness of neutrophil count ≥ 500/mm3 and <1000/mm3. 
• 
Discontinuation of study drug is maintained until the neutrophil count returns to ≥ 
1000/mm3 (Appendix L).  
• 
After the patient meets all requirements for resumption of study drug administration, 
including neutrophil count ≥ 1000/mm3, then study drug administration may resume at the 
dose of 150 mg q2w.  
In case of a decrease in neutrophil count < 500/mm3 or if neutrophil count < 1000/mm3 and signs 
of infection: 
• 
Study drug must be permanently discontinued. 
• 
The patient must be assessed for evidence of infection and CBC blood test repeated within 
48 hours from the study Investigator’s awareness of neutrophil count < 500/mm3, or 
< 1000/mm3 and signs of infection. 
• 
It is recommended to admit the patient to the hospital in case of neutrophil count 
< 1000/mm3 with suspicion of infection.  
• 
Neutrophil count <500/mm3 persisting for at least 5 days is to be reported as a serious 
adverse event.

For all patients, a CBC test must be performed a few days before or at Visit 3, but not earlier than 
the 12th day after the first dose of IMP administration (using either designated central lab or local 
laboratory facility), and results reviewed prior to the administration of the 2nd dose of study drug 
in order to confirm that the platelet count is not within the protocol-defined limits for temporary, 
or permanent discontinuation of study drug. 
For all subsequent visits, in order to prevent the administration of study drug in patients at risk for 
thrombocytopenia, whenever the platelet count is below the LLN based on designated central 
laboratory test specifications, the CBC test must be repeated to confirm that the platelet count is 
not within the protocol-defined limits for temporary, or permanent discontinuation of study drug, 
before the next administration of study drug. The outlined procedures below will be followed: 
- 
Contact patient as soon as possible and schedule “repeat CBC blood test”; the repeat 
blood test can be arranged using designated central lab or a local laboratory facility. 
- 
If the results of the “repeat CBC blood test” (either designated central lab or local 
laboratory facility results) confirm that the platelet count is ≥ 100,000/mm3 (100 GI/L), 
the study drug may be administered. 
- 
If the results of the “repeat CBC blood test” (either designated central lab or local 
laboratory facility results) demonstrate that the platelet count is below 100,000/mm3 
(100 GI/L), the study drug must be temporarily or permanently discontinued, per 
protocol stopping rules defined below, and in Appendix L. 
- 
Note:  All per protocol-scheduled CBC tests must be performed using designated 
central lab, even in circumstances when a local laboratory facility is also used to 
determine the platelet count before dosing. 
In case of a decrease in platelet count to a level ≥ 50,000/mm3 and < 100,000/mm3: 
- 
Study drug must be temporarily discontinued; the patient must be assessed for 
evidence of spontaneous bleeding, and CBC blood test repeated within 48 hours from 
the study Investigator’s awareness of platelet count ≥ 50,000/mm3 and < 100,000/mm3. 
- 
Discontinuation of study drug is maintained until the platelet count returns to 
≥100,000/mm3 (see Appendix L). 
- 
After the patient meets all requirements for resumption of study drug administration, 
including platelet count ≥100,000/mm3, then study drug administration may resume at 
the dose of 150 mg q2w.  
The study drug must be permanently discontinued if platelet count is <50,000/mm3 or if 
<100,000/mm3 with spontaneous bleeding (see Appendix L).   
10.2.7 Systemic Hypersensitivity reactions / Anaphylaxis 
Severe, systemic hypersensitivity reactions (in rare cases fatal anaphylaxis), have been reported to 
occur following exposure to biological drugs, including tocilizumab. Infrequent, mild to 
moderate, systemic hypersensitivity reactions have been observed with sarilumab.

Patient at study site visits should be monitored for 30 min after the injection.  Patients that self-
administer IMP should be aware of the clinical signs and symptoms of allergic reactions, and limit 
strenuous activity for 30 minutes after self-injection.  Any problem should be documented in the 
patient’s diary or medical notes.  In case of systemic hypersensitivity reaction, including 
anaphylaxis (see Appendix O for the clinical criteria for diagnosing anaphylaxis), the study drug 
should be permanently discontinued and the study Investigator should determine if the event 
qualifies for serious adverse event reporting (see Section 10.4 and Section 10.5.2).  If the clinical 
criteria for diagnosing anaphylaxis are met per Appendix O, then appropriate treatment should be 
administered immediately and the adverse event must be reported as an SAE and AEPM/AESI 
with immediate notification. 
10.2.8 Diverticulitis and Gastrointestinal perforation  
Gastrointestinal perforations have been reported as complications in patients with diverticulitis 
who have been treated with tocilizumab.   
Gastro-intestinal perforation is an AESI with immediate notification to be reported as SAE.  
Confirmed diverticulitis or gastrointestinal ulceration should be reported as AESI without 
immediate notification (see Section 10.5.4). 
The Investigator should pay particular attention to all gastrointestinal symptoms such as, but not 
limited to, abdominal pain, haemorrhage or unexplained change in bowel habits with fever to 
assure that the diagnosis is not missed and that the conditions are managed appropriately to avoid 
the complication of perforation.  If necessary, the patient should be referred to a specialist.   
Corticosteroid use or prior history of diverticulitis is known to increase the risk of gastrointestinal 
perforations. The Investigator should be aware of this potential risk and monitor any sign of 
diverticulitis. 
10.2.9 Acute renal failure 
See Appendix L.  Sarilumab is not known to be associated with a clinically significant effect on 
renal function. 
10.2.10 Management of dyslipidaemia, cardiovascular events, and deaths 
Patients treated with tocilizumab have been observed to have increased elevations of all lipid 
parameters, including LDL cholesterol.  A similar finding has been observed for sarilumab. The 
potential cardiovascular effect of the lipid elevations, including LDL levels in this population of 
RA patients treated with anti-IL-6 antagonists, is unknown.   
As rheumatoid arthritis is a known independent risk factor for cardiovascular events, patients who 
are found to have dyslipidemia during the course of the study should be treated according to the 
National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP) III or applicable 
local guideline (http://www.nhlbi.nih.gov/guidelines/cholesterol/atp3full.pdf).

Specific cardiovascular events, as listed in Section 10.5.4, and all deaths will be reported as AESI 
with immediate notification and should always be reported as serious adverse events. These 
events will be subject to an adjudication process via the Cardiovascular Adjudication Committee 
described in Section 6.4.2.  
10.3 
ADVERSE EVENTS MONITORING 
All events will be managed and reported in compliance with all applicable regulations, and 
included in the final clinical study report. 
10.4 
DEFINITIONS OF ADVERSE EVENT (AE) AND SERIOUS ADVERSE EVENT (SAE) 
An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation 
in a patient to whom a pharmaceutical product has been administered, and which does not 
necessarily have to have a causal relationship with this treatment. 
An Adverse Event of Special Interest also known as an Adverse Event of Pre-specified 
Monitoring (AEPM/AESI)  is an AE (serious or non-serious) of scientific and medical concern 
specific to the Sponsor’s product or program, for which ongoing monitoring and rapid 
communication by the Investigator to the Sponsor may be appropriate. Such events may require 
further investigation in order to characterize and understand them. The AESI/AEPMs may be 
added or removed during a study by protocol amendment. 
A Serious Adverse Event (SAE) is any untoward medical occurrence that at any dose: 
• 
Results in death or; 
• 
Is life-threatening or; 
Note:  The term “life-threatening” in the definition of “serious” refers to an event in which the 
patient was at risk of death at the time of the event; it does not refer to an event which 
hypothetically might have caused death if it were more severe. Requires inpatient hospitalization 
or prolongation of existing hospitalization or 
• 
Results in persistent or significant disability/incapacity or 
• 
Is a congenital anomaly/birth defect 
• 
Is a medically important event: 
Medical and scientific judgment should be exercised in deciding whether expedited reporting is 
appropriate in other situations, such as important medical events that may not be immediately 
life-threatening or result in death or hospitalization but may jeopardize the patient or may require 
intervention (ie, specific measures or corrective treatment) to prevent one of the other outcomes 
listed in the definition above. 
Note:  The following medical important events intend to serve as a guideline for determining 
which condition has to be considered as a medically important event.  It 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…), 
-

Chronic neurodegenerative diseases, newly diagnosed or aggravated during the study. 
10.5 
OBLIGATION OF THE INVESTIGATOR REGARDING SAFETY REPORTING 
10.5.1 Adverse Events 
All AEs regardless of seriousness or relationship to IMP/NIMP, spanning from the signature of 
the informed consent form, until the end of the study as defined by the protocol for that patient, 
are to be recorded on the corresponding page(s) or screen(s) included in the CRF. 
Whenever possible, diagnosis or single syndrome should be reported instead of symptoms.  The 
Investigator should specify the date of onset, intensity, action taken with respect to IMP, 
corrective treatment/therapy given, additional investigations performed, outcome and his/her 
opinion as to whether there is a reasonable possibility that the AE was caused by the IMP or the 
NIMP (not assessed in EFC13752 patients). 
The Investigator should take appropriate measures to follow all AEs until clinical recovery is 
complete and laboratory results have returned to normal (or baseline), or until progression has 
been stabilized, or until death, in order to ensure the safety of the patients. This may imply that 
observations will continue beyond the last planned visit per protocol, and that additional 
investigations may be requested by the Sponsor.  
• 
Patients who experience an ongoing SAE or an AESI with immediate notification, at the 
pre-specified study end-date, should be followed until resolution, stabilization, or death 
and related data will be collected.  
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.

Laboratory, vital signs or ECG abnormalities are to be recorded as AEs only if they are medically 
relevant: symptomatic or requiring either corrective treatment or consultation or leading to 
discontinuation or modification of dosing and/or fulfilling a seriousness criterion and/or is defined 
as an AE with pre-specified monitoring (AEPM/AESI). 
10.5.2 Serious Adverse Events 
In the case of a serious adverse event the Investigator must immediately: 
• 
ENTER (within 24 hours of knowledge) the information related to the SAE in the 
appropriate screens of the e-CRF; the system will automatically send the notification to the 
Monitoring Team after approval of the Investigator within the e-CRF or after a standard 
delay. 
• 
SEND (preferably by fax or e-mail) the photocopy of all examinations carried out and the 
dates on which these examinations were performed, to the representative of the 
Monitoring Team whose name, fax number and email address appear on the Clinical Trial 
Protocol.  Care should be taken to ensure that the patient's identity is protected and the 
patient's identifiers in the Clinical Trial are properly mentioned on any copy of source 
document provided to the Sponsor.  For laboratory results, include the laboratory normal 
ranges. 
• 
All further data updates should be recorded in the e-CRF as appropriate, and further 
documentation as well as additional information (for Lab data, concomitant Medication, 
patient status.) should be sent (by fax or e-mail) to the Monitoring Team within 24 hours 
of knowledge.  In addition, any effort should be made to further document each Serious 
AE that is fatal or life threatening within the week (7 days) following initial notification. 
• 
A back-up plan is used (using paper flow) when the e-CRF system does not work. 
• 
In case of 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, this should be reported to the Monitoring team. 
10.5.3 Deleted  
10.5.4 Adverse events of special interest/Adverse events with pre-specified monitoring 
(AESI/AEPM) 
The needs for specific monitoring, documentation, and management of AEPM/AESIs are 
described in this section.   
The decision to report AEPM/AESI as a SAE is the same as for any adverse event; if the event 
meets any seriousness criteria as per the Investigator’s judgment, it should be reported as an SAE.  
If the AEPM (just as any other adverse event) does not meet seriousness criteria as per the 
Investigator’s judgment, it should be reported as a nonserious event.  Certain AEPM/AESI will 
require immediate notification to the Sponsor, even if not fulfilling seriousness criteria, while 
others will not.

The follow-up of the pregnancy in a female participant or in a female partner of a male 
participant will be mandatory until the outcome has been determined. 
• 
Symptomatic Overdose with IMP/NIMP: 
- 
An overdose (accidental or intentional) with the IMP is an event suspected by the 
Investigator or spontaneously notified by the patient and defined as at least twice the 
dose of IMP during an interval of less than 11 days (NOTE: this definition was less 
than 6 days for patients on the initial weekly dosing regimen in the study). The 
circumstances (ie, accidental or intentional) should be clearly specified in the verbatim 
and symptoms, if any, entered on separate AE forms.

OBLIGATIONS OF THE SPONSOR 
During the course of the study, the Sponsor will report in an expedited manner all SAEs that are 
both unexpected and at least reasonably related to the IMP Suspected Unexpected Serious 
Adverse Reaction (SUSAR), to the Health Authorities, IECs/IRBs as appropriate and to the 
Investigators. 
In addition, the Sponsor will report in an expedited manner all SAEs that are expected and at least 
reasonably related to the IMPs to the Authorities, according to local regulations. 
In this study, some AEs are considered related to the underlying condition and thus will not be 
considered unexpected: eg, arthralgia related to RA. 
Any other AE not listed as an expected event in the Investigator’s Brochure or in this protocol 
will be considered as unexpected. 
The Sponsor will report all safety observations made during the conduct of the trial in the clinical 
study report (CSR).

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 if 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. 
11.1 
TEMPORARY TREATMENT DISCONTINUATION WITH INVESTIGATIONAL 
PRODUCT(S) 
Temporary treatment discontinuation may be considered by the Investigator because of suspected 
AEs eg, suspected malignancy or because of abnormal laboratory values.  
The following is a list of criteria for temporary discontinuation. This list is not exhaustive and 
IMP may be temporarily discontinued for additional reasons based on Investigator judgment: 
• Increase in ALT level ≥3 x ULN to ≤5 x ULN and bilirubin ≤2 x ULN (unless the patient 
has documented Gilbert’s disease). The IMP can be resumed at the dose of 150 mg q2w 
only after the ALT has returned to a value <3 ULN and all requirements for resumption of 
study drug administration are met (see Section 10.2.4 and Appendix L).  
• Decrease in neutrophil count to a level between 500/mm3 to <1000/mm3 without signs 
and symptoms of a potential infection. The IMP can be resumed at the dose of 150 mg 
q2w only after the neutrophils have returned to a value ≥1000/ mm3 and all requirements 
for resumption of study drug administration are met (see Section 10.2.5 and Appendix L). 
• Decrease in platelet count to between 50 000 cells/mm3 to < 100 000 cells/mm3 without 
spontaneous bleeding. The IMP can be resumed at the dose of 150 mg q2w only after the 
platelet count is ≥100 000/mm3 and all requirements for resumption of study drug 
administration are met (See Section 10.2.6 and Appendix L). 
• Infections requiring oral or parenteral treatment with antibacterial, antiviral and/or 
antifungal agents (See Section 10.2.1 for additional guidance) 
• Surgery requiring temporary treatment discontinuation of biologic DMARD as per 
applicable guidelines 
If the dose is reduced to 150 mg q2w the reduced dose will be maintained for the whole duration 
of the treatment period.  
The IMP can be temporarily discontinued for ≤59 days (3 IMP doses can be missed). 
Reinitiation of treatment with the IMP will be done under close and appropriate clinical/and or 
laboratory monitoring.

Page 73 
If the restart of the IMP occurs later than 38 days since the last IMP dose (2 IMP doses were 
already missed), the IMP has to be administered at the study site and the patient to be observed for 
30 minutes for any medical events. 
NOTE: in case of prolonged decreased neutrophil count to a level between 500/mm3 to 
<1000/mm3 without signs and symptoms of a potential infection and/or prolonged increased ALT 
level ≥3 x ULN to ≤5 x ULN detailed work-up should be performed before sarilumab is 
reinitiated to rule out other potential causes of neutropenia or ALT elevation. 
11.2 
PERMANENT TREATMENT DISCONTINUATION WITH INVESTIGATIONAL 
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. 
11.2.1 List of criteria for definitive treatment discontinuation 
The patients may withdraw from treatment with IMP if they decide to do so, at any time and 
irrespective of the reason, or this may be the Investigator’s decision.  All efforts should be made 
to document the reasons for treatment discontinuation and this should be documented in the 
e-CRF. 
Study drug will be permanently discontinued in case of the following events: 
• 
Confirmed diagnosis of opportunistic infection based on the investigator’s assessment 
following diagnostic workups and expert consultations 
• 
Active tuberculosis: 
- 
the diagnosis can be made either on symptoms or on a chest radiograph suggestive of 
active TB.  Patients should be referred to appropriate medical specialists and whenever 
possible, culture confirmation of disease should be obtained and recorded in the 
e-CRF. 
• 
The patient is at risk through close contact with a person with active TB and the patient 
refuses to undergo TB evaluation. 
• 
Culture positive for non-tuberculosis mycobacteria 
• 
Symptoms of systemic hypersensitivity or anaphylactic reactions. 
• 
Severe neurologic disease such as demyelinating disease or PML. 
• 
Significant laboratory abnormalities:   
- 
ALT> 5xULN or ALT>3xULN with concomitant total bilirubin >2xULN (unless 
patient with documented Gilbert´s syndrome) 
- 
neutrophil count <500/mm3, or neutrophil count <1000/mm3 with evidence of infection

platelet count <50 000/mm3, or platelet count <100 000/mm3 with evidence of 
bleeding (see Section 10.2). 
• 
Conversion to HIV positive status 
• 
Acute renal failure 
• 
Pregnancy in female participant. 
• 
Use of any biologic DMARDs other than IMP,  or use of any JAK inhibitor 
• 
For EFC13752 patients: use of any non-biologic DMARDs 
• 
Any adverse events, per investigator judgment, that may jeopardize the patient safety. 
11.2.2 Handling of patients after permanent treatment discontinuation 
Patients will be followed up according to the study procedures as specified in this protocol up to 
the scheduled date of study completion, or up to recovery or stabilization of any AE to be 
followed-up as specified in this protocol, whichever comes last: 
• If possible, and after the permanent discontinuation of treatment, the patients will be 
assessed using the procedures normally planned for the end of treatment visit and the 
follow up visit 6 weeks later. 
All permanent treatment discontinuation should be recorded by the Investigator in the appropriate 
pages when considered as confirmed.  
11.3 
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 end-of 
treatment visit and post treatment safety follow-up visit. 
For patients who fail to return to the site, the Investigator should make the best effort to re-contact 
the patient (eg, contacting patient’s family or private physician, review available registries or 
health care database), and to determine his/her health status, including at least his/her vital status.  
Attempts to contact such patients must be documented in the patient’s records (eg, times and dates 
of attempted telephone contact, receipt for sending a registered letter). 
Patients who have withdrawn from the study cannot be enrolled again (treated) in the study.  Their 
inclusion and treatment number must not be re-used.

STUDY PROCEDURES 
12.1 
VISIT SCHEDULE 
It is preferred that all study visits take place in the morning.  Some visits that include only 
scheduled blood sampling (V3, V5, V6.1) (Week 2, Week 6, and Week 10) can be scheduled as 
Home Visits or clinic visits. 
Patients will be considered as having completed their treatment per protocol and should complete 
the end of treatment visit (EOT): 
• 
At Week 264, if sarilumab has been commercialized in their country at that time. EOT 
visit should be performed instead of Week 264 visit and the assessments defined in the 
flowchart (Section 1.2.1, Section 1.2.2) should be completed. 
• 
At any visit after Week 264 once sarilumab is commercialized in their country (applicable 
for patients in the countries where commercial sarilumab is not available at the time the 
patients completed their Week 264). Some of the assessments are NOT required at EOT 
for these patients; please refer to the flowchart (Section 1.2.1, Section 1.2.2) for details.  
- 
When commercialization occurs in a given country, investigators in that country will 
be alerted by the Sponsor and they will inform their patients during the next scheduled 
study visit that their subsequent visit 12 weeks later will be the EOT visit. 
• 
At any visit after Week 264 at the time the study is closed in 2020 in countries where 
commercialization has still not occurred. Some of the assessments are NOT required at 
EOT for these patients; please refer to the flowchart (Section 1.2.1, Section 1.2.2) for 
details. 
- 
EOT visits for all patients remaining in the study at that time will occur at scheduled 
clinic visits over a 3-month period in order to stagger the completion of EOT visits 
across the study, and allow the completion of the 6-week follow up period for all 
patients prior to study closure. Investigators will be alerted by the Sponsor that the 
study closure is approaching and they will inform their patients during the next 
scheduled study visit that their subsequent visit 12 weeks later will be the EOT visit. 
• 
At Week 264, for patients in the UK no matter when the sarilumab is commercially 
available in the country. EOT visit should be performed instead of Week 264 visit and 
assessments defined in the flowchart (Section 1.2.1, Section 1.2.2) should be completed. 
If a patient is permanently and prematurely discontinued from treatment, all assessments planned 
at the end of treatment visit (EOT) should be performed.  Some assessments at EOT are not 
required if the EOT visit occurs after Week 264, as indicated in the flowchart. 
The safety follow-up visit should be performed six weeks from the end of treatment for all 
patients including those who discontinued before the planned end of treatment with the following 
exception:

• 
In patients who complete sarilumab treatment per protocol in countries where sarilumab is 
commercially available the post treatment follow-up visit may be cancelled if the patient 
initiates treatment with commercial sarilumab during the post treatment follow-up period. 
However, in this case, a telephone contact must be established with the patient to capture 
all AEs occurring up to the 1st administration of commercial sarilumab.  
From Week 24 (Visit 8) onwards, some patients may participate in the PFS-S sub-study. No 
details of the sub-study assessments are described in this section. Please refer to the Appendix R 
for all information related to the sub-study assessments for these patients. 
12.1.1 Visit 1:  Screening Visit (D-7 to D-1)

specific time periods for each treatment group.  The time periods of interest will be specified in 
the statistical analysis plan. 
13.5.3.2 Compliance 
Treatment compliance is defined as the actual amount of drug taken compared to the scheduled 
amount of treatment.  It is calculated according to the following formula: 
100 x total number of compliant injections administered / [nominal number of injections for the 
duration of exposure]. 
A given administration will be considered as 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. 
Treatment compliance will be summarized using means, standard deviations, medians, minimums 
and maximums.  In addition, the percentage of patients with <80% treatment compliance will be 
summarized. 
13.5.4 Analyses of safety data 
The review of safety and tolerability will be performed based on the safety population, as defined 
in Section 13.4 .  The safety analyses will be presented based on the reported adverse events, 
clinical laboratory evaluations, vital signs, and 12-lead ECGs. 
The following definitions will be applied to laboratory parameters, vital signs and ECG. 
• 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, vital signs and ECG.   
• PCSA criteria will determine which patients had at least 1 PCSA during the treatment-
emergent period, taking into account all evaluations performed during the treatment-
emergent period, including nonscheduled or repeated evaluations. The number of all such 
patients will be the numerator for the treatment-emergent PCSA percentage. 
13.5.4.1 Adverse events 
Adverse events reported in this study will be coded using the Medical Dictionary for Regulatory 
Activities (MedDRA) in effect at sanofi at the time of database lock. Treatment-emergent adverse 
events (TEAEs) are AEs that developed or worsened or became serious during the TEAE period.

discontinuation will be summarized by primary SOC, HLGT, HLT, and PT. 
Adverse events of special interest (AESI) 
AESIs will be flagged using search criteria. If available, a Standard MedDRA Query (SMQ) will 
be used to search (narrow search).  If no SMQ is available, then a Sponsor defined search criteria 
will be used. The number and percentage of patients with treatment emergent AESIs will be 
summarized by AESI category and PT. 
13.5.4.2 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 
visit by baseline status will be displayed by treatment group for each parameter. The proportion of 
patients with PCSA values at any visit may be displayed by duration of exposure for each 
treatment group.

13.5.5 Analyses of efficacy endpoints 
There will be no confirmatory analysis for the efficacy variables. All analysis will be done 
descriptively on the safety population by visit in observed case, as appropriate. 
For categorical variables, for example, percentage of patients who have maintained/reached 
ACR20 overtime, the number and percentage will be provided from all patients who have data 
available at that time point, and the 95% confidence intervals will be calculated if appropriate. 
For continuous variables, descriptive statistics such as the mean, standard deviation, median, 
minimum and maximum will be provided.  In addition, 95% confidence interval of the mean will 
be presented. This applies to the original values and change (or percent change) from baseline. 
Change from baseline in the van der Heijde modified total Sharp scores (mTSS) will be 
summarized for patients from EFC11072 Part B only.  Descriptive statistics, including the mean, 
standard deviation, median, minimum and maximum will be provided, along with 95% 
confidence intervals.  The actual values will be similarly summarized. 
Radiographic progression of the mTSS is defined as a change from baseline in the mTSS > 0. A 
change from baseline in the mTSS of less than or equal to zero is considered as no progression. 
The event of missing a change from baseline in the mTSS will be considered as progression. 
Summary of incidence of radiographic progression of mTSS will be provided. 
Additional sensitivity analyses may be performed if necessary. 
13.5.6 Analyses of pharmacokinetic and pharmacodynamic variables

Serum concentrations of functional sarilumab will be summarized using standard descriptive 
statistics such as arithmetic and geometric means, standard deviation (SD), standard error of the 
mean (SEM), coefficient of variation (CV%), minimum, median, and maximum by dose and visit. 
Serum concentrations of bound (serum sarilumab-sIL-6Rα complex) and functional sarilumab 
were intended to be analyzed in the study. After the completion of EFC11072 Part B study, the 
Sponsor made the decision to only analyze functional sarilumab concentrations. Serum 
concentrations of bound sarilumab (serum sarilumab-sIL-6Rα complex) will not be summarized 
in this study.

13.5.6.2 Immunogenicity variables 
Anti-sarilumab antibody (ADA) assay results will be described categorically. The summary will 
be provided for patients with any positive ADA assay response during the TEAE period.  
Patients with any positive ADA assay response are defined as: 
• Patients with no positive assay response at baseline but with a positive assay response 
during the TEAE period or 
• Patients with a positive ADA assay response at baseline and also have at least a 4-fold 
increase in titer during the TEAE period. 
13.5.6.3 Pharmacodynamic descriptive analysis 
Serum concentrations of IL-6 will be summarized using arithmetic and geometric means, SD, 
SEM, CV%, minimum, median, and maximum by dose and visit.

summarized using raw value and change from baseline at each visit or study assessment (baseline, 
endpoint) by dose. 
Change from baseline in the 4 WPAI scores will be summarized using raw value and change from 
baseline at each visit or study assessment (baseline, endpoint) by dose. 
Change from baseline in the FACIT-Fatigue score and the sleep VAS will be summarized using 
raw value and change from baseline at each visit or study assessment (baseline, endpoint) by dose. 
Change from baseline in the 8 WPS-RA scores will be summarized using raw value and change 
from baseline at each visit or study assessment (baseline, endpoint) by dose (for the patients from 
EFC10832 only). 
13.6 
DATA HANDLING CONVENTIONS 
Missing dates will be handled using conservative approaches, and no imputation will be applied at 
the data level: 
• If the date of the last dose of investigational drug is missing, duration of exposure will be 
set to missing. 
• Handling of PCSAs: If a subject has a missing baseline value, he will be grouped in the 
category “normal /missing at baseline.”  For PCSA with 2 conditions, one based on a 
change from baseline value or a normal range and the other one on a threshold value, the 
first condition being missing, the PCSA will be based only on the second condition.  For 
PCSA defined on a threshold and/or a normal range, this PCSA will be derived using this 
threshold only if the normal range is missing.  For example, for eosinophils the PCSA is

INTRODUCTION AND RATIONALE 
4.1 
 PRE-FILLED SYRINGE WITH SAFETY SYSTEM (PFS-S) 
Sarilumab has been delivered via prefilled syringes (PFS) in most of the Phase 3 studies.  
The pre-filled syringe with safety system (PFS-S) is a modified version of the prefilled syringe 
aimed at preventing needle stick injury by either the patient or by a caregiver (professional or 
non-professional) performing the administration. The “safety system” consists of a sharps injury 
prevention feature, which can be described as a sheath that automatically covers the needle once 
the injection is completed and thus prevents needle stick injury and re-use.  
Compared to PFS, PFS-S also includes: 
• 
a rigid needle shield that encloses the soft rubber needle shield covering the needle  
• 
a finger flange with an ergonomic design and a large piston rod 
The following figures show the unused and used PFS-S. At the end of the injection when the 
plunger rod has been pushed into the syringe as far as it will go, the needle safety shield is 
activated which can be seen as the syringe is pulled away from the skin.

SUB-STUDY RATIONALE 
This sub-study is aimed to assess the usability of the PFS-S syringe when used by patients with 
moderate or severe RA, or their professional or non-professional healthcare providers in an 
unsupervised real-world situation.  To mimic the real-world practice, the sub-study was designed 
to incorporate into the LTS11210 study without additional visits compare to scheduled visits in 
the main study. 
The primary endpoint is the number of product technical failures (PTF), which is defined as any 
product technical complaint (PTC) that has a validated technical cause. A PTC is defined as any 
patient- or healthcare provider-reported complaint regarding the use of the PFS-S syringe and 
collected via the completion of the injection diary.  
In addition, the safety information of sarilumab 150 mg q2w PFS-S and 200 mg q2w PFS-S will 
be collected throughout the sub-study period and trough concentrations of sarilumab will be 
measured at entry into the sub-study and at the end of the 12-week sub-study period.

STUDY DESIGN 
6.1 
DESCRIPTION OF THE PROTOCOL 
This is a Phase 3, multicenter, worldwide, non-randomized, open-label, 1-arm, 12-week sub-study 
of the LTS11210/SARIL-RA-EXTEND study. The sub-study will only be performed in limited 
sites in selected countries.  
Patients at participating sites who have been enrolled in the main study (LTS11210) for at least 24 
weeks and are willing to participate in the sub-study will be enrolled in the sub-study. The entry 
into the sub-study (V101) will be at any scheduled visit in the main study from Visit 8 (Week 24) 
or after. Sarilumab 150 mg q2w PFS-S or sarilumab 200 mg q2w PFS-S will be used in the sub-
study to replace the sarilumab 150 mg q2w PFS or 200mg q2w PFS used in the main study. At the 
entry into the sub-study (V101), the patients will be trained how to use the PFS-S, and the sub-
study injection diary will be dispensed to replace the patient diary of the main study. All the 
procedures described in the sub-study are additional to the main study activities, unless specified 
to replace procedures in the main study. 
The person performing each sub-study injection will respond to 3 questions related to PFS-S use 
on the injection diary (See Section 9.1) after each PFS-S injection. A “no” response to any 
question will be defined as a PTC. For any PTC, the Investigator will complete a PTC form and 
will send this PTC form together with the PFS-S that triggered this PTC back to the Sponsor 
according to a predefined process (Section 12). The patients should be instructed to keep any PFS-
S associated with a PTC separately from other PFS-S, so it can be identified when returned to site 
at the end of sub-study. 
For patients receiving sarilumab 200 mg q2w PFS-S the dose can be reduced any time during the 
sub-study duration if the main protocol defined criteria for dose reduction are fulfilled. 
When the patients have completed the 12 weeks of the sub-study they will return to the clinic to 
complete Visit 102 in addition to the scheduled main study visit on that day. They will switch 
back to the main study and continue sarilumab PFS treatment.  
If the patient chooses to end the participation in the sub-study during the sub-study duration but to 
continue in the main study the Visit V102 should still be completed. 
If a patient discontinues Investigational Medicinal Product (IMP) permanently in LTS11210 
during the sub-study, he/she should complete all procedures planned for V102 in the sub-study as 
well as the end of treatment (EOT) and post treatment follow-up visits in the main study (see 
flowchart in main study Section 1.2).

DURATION OF STUDY PARTICIPATION 
6.2.1 Duration of study participation for each patient 
Each patient will participate in the sub-study for a period of 12 weeks from the first sub-study 
visit (V101) to the final sub-study visit (V102). At the time of V101, eligible patients will start 
receiving sarilumab 150 mg q2w PFS-S or sarilumab 200 mg q2w PFS-S for 12 weeks as 
replacement of original sarilumab PFS in the main study and on top of the background disease 
modifying anti-rheumatic drugs (DMARDs) therapy, if any. There is no post-treatment follow-up 
specific to the PFS-S sub-study, as all patients will switch back to the main study at V102.  
6.2.2 Determination of end of sub-study (all patients) 
The last on-treatment sub-study visit for patients who complete the sub-study will occur at Day 85 
(Visit 102). The sub-study will be considered completed when the last sub-study patient has 
completed V102.

STUDY TREATMENTS 
8.1 
INVESTIGATIONAL MEDICINAL PRODUCT(S) 
Investigational Medicinal Product  
Sarilumab, anti-IL-6R mAb (anti-interleukin 6 receptor monoclonal antibody) 
Pharmaceutical form  
1 mL long glass prefilled syringes with a needle safety shield (PFS-S) filled to a nominal injection 
volume of 1.14 mL with drug product at 131.6 mg/mL (150 mg) or 175 mg/mL (200 mg) 
Dose per administration 
• 
Single-use administration of sarilumab by PFS-S 
• 
Dose of either 150 mg or 200 mg q2w 
NOTE: Patients should continue to receive the same sarilumab dose as they have received in the 
main study, unless they fulfill main protocol defined criteria for dose reduction. 
Route and method of administration 
The route and administration method of sarilumab PFS-S used in the sub-study are same as 
sarilumab PFS used in the main study.  
 
Each sub-study injection will be performed by the patient, or their caregiver.  In exceptional 
circumstances (such as the 1st administration using PFS-S) the injection may be performed by the 
site staff. The patient or their caregiver will be trained on performing the injection with the PFS-S 
using a patient user instruction specific to the use of the PFS-S and a training PFS-S filled with 
sucrose together with an injection pad. This training must be documented in the patient’s study 
file. 
Duration of administration of PFS-S 
12 weeks (6 injections)

8.4 
METHOD OF ASSIGNING PATIENTS TO TREATMENT GROUP 
This is a 1-arm open-label sub-study, no randomization will be performed for the study.  
At the sub-study entry (V101/D1), after the patient has given informed consent and the patient’s 
eligibility has been confirmed, the site staff will contact the IVRS/IWRS in order to enroll the 
patient into the sub-study and to allocate the sub-study treatment kits. Either sarilumab 150 mg 
q2w PFS-S or sarilumab 200 mg q2w PFS-S will be allocated to each patient. The allocated dose 
will be the same as in the main study except if conditions for dose reduction are met. 
The sub-study patients will continue to use the same patient number assigned during enrollment 
into the main study, which consists of 9 digits (3 digits indicating the country, 3 digits indicating 
the site and 3 digits indicating the patient) 
8.5 
PACKAGING AND LABELING 
The IMP (sarilumab in PFS-S) will be provided in a patient treatment kit box. The kit will be 
labeled in accordance with the local regulatory specifications and requirements, along with 
content information, dosing instructions, and precautionary statement (“for clinical use only”). A 
sub-study treatment kit has specific labeling that distinguishes syringes in a treatment kit. They 
are labeled “Dose 1” and “Dose 2”.  
Packaging is in accordance with the administration schedule. The number of treatment kits 
allocated to the patient will provide sufficient medication until the next clinic visit. Additional 
treatment kits, to provide medication to patients under circumstances, such as a damaged kit, will 
be allocated by IVRS/IWRS when a “replacement treatment call“ is made to IVRS/IWRS.  
8.6 
STORAGE CONDITIONS AND SHELF LIFE 
The storage conditions and shelf life of sarilumab PFS-S used in the sub-study are the same as 
sarilumab PFS used in the main study. 
8.7 
RESPONSIBILITIES 
Site personnel responsibilities in the sub-study are the same as in the main study. 
8.7.1 Treatment accountability and compliance 
The completed injection diary should be returned by the patient at the end of the sub-study 
(V102/D85). 
All PFS-S medication treatment kits (with all used or unused PFS-S) must be returned by the 
patient at the end of the sub-study (V102/D85).

Page 160 
The study coordinator will track treatment accountability/compliance of PFS-S by comparing the 
information recorded in the patient diary with the number of returned treatment boxes and 
used/unused PFS-S and fill in the appropriate page of the patient treatment log. 
The monitor in charge of the study will then check the data entered on the e-CRF IMP 
administration page by comparing them with the IMP that has been retrieved and the patient 
treatment log. 
8.7.2 Return and/or destruction of treatments 
All used and unused PFS-S will be collected by the study site at V102/D85. All used PFS-Ss for 
which a PTC was reported will be returned to the Sponsor. 
At selected sites, used PFS-S which functioned normally with no PTC will be returned to the 
Sponsor as well. 
Used PFS-S with complaints regarding labeling, packaging or a cosmetic defect of the PFS-S, will 
not be further investigated as a part of the sub-study. 
A detailed treatment log of the returned PFS-S returned to the sponsor will be established with the 
Investigator (or the pharmacist) and countersigned by the Investigator and the monitoring team.

ASSESSMENT OF INVESTIGATIONAL MEDICINAL PRODUCT 
9.1 
PRIMARY ENDPOINT 
The primary endpoint is the number of validated PFS-S-associated PTFs. A PTF is defined as any 
PTC related to the use of the PFS-S which has a validated technical cause. A PTC is defined as 
any patient- or healthcare provider-reported complaint regarding the use of the PFS-S syringe and 
collected via the completion of the injection diary.  
The injection diary will include specific questions about PTCs. The person performing each sub-
study injection will record the answers to these questions in the diary each time he/she performs 
an injection with a PFS-S. 
The questions include: 
1. Were you able to remove the cap? 
a) Yes 
b) No 
i 
If no, please describe / explain:  
2. Was the needle safety system activated?  
a) Yes 
b) No 
i 
If no, please describe / explain:  
3. Did the safety system entirely cover the needle? 
a) Yes 
b) No 
i 
If no, please describe / explain:  
At Visit 102, the Investigator will review the diary, confirm with the patient whether there were 
any problems associated with the use of PFS-S either during drug administration or otherwise, and 
record the responses in the e-CRF.   
If the answer is “no” to any of the questions stated in the diary, the patients will be asked to 
provide further details of the complaint and a PTC form will be completed by the investigator. 
The PTC form and the PFS-S associated with PTC will be sent to the Sponsor following the 
process defined in Section 12. The sponsor will validate or invalidate the occurrence of a PTF. If 
the PTF is ruled out the event is considered as a failed drug delivery (FDD) and is defined as 
patient’s failure to administer the full dose at a given attempt.

STUDY PROCEDURES 
10.1 
VISIT SCHEDULE 
All the procedures performed in the sub-study are in addition to those planned in the main study 
unless sub-study procedures replace the main study procedures. 
10.1.1 Visit 101: Entry of sub-study / Day 1 
A sub-study specific written informed consent form must be signed by the patient prior to any 
sub-study procedure being performed. 
The following items will be checked and recorded by the Investigator or designee: 
• 
Assess eligibility by review of inclusion criteria. 
• 
Before sarilumab administration, obtain blood sample for PK (serum sarilumab) and anti-
sarilumab antibodies assessment. If the sub-study visit coincides with a PK and ADA 
sampling time point in the main study, no samples are required to be obtained for the sub-
study. 
• 
Access IVRS/IWRS to enroll patient into the sub-study and to allocate sub-study IMP. 
NOTE: this replaces the scheduled resupply IVRS/IWRS transaction for the main 
scheduled study visit. 
• 
Dispense sarilumab PFS-S. 
• 
Dispense sub-study injection diary, provide instructions for use, and remind the patient to 
complete the diary after each injection and to bring the completed diary back to the site at 
next visit. 
• 
Provide training on injection using a patient user instruction specific to the use of the 
PFS-S and a PFS-S prefilled with sucrose together with a pad. Allow the patient or the 
caregiver to inject into the training pad under observation, provide feedback on technique. 
This training must be documented in the patient’s study file. 
• 
The first dose of IMP will be administered by the patient or caregiver or study 
doctor/nurse at the study site and an appropriate record will be made in the source data by 
the person who performed the injection using the injection diary. 
10.1.2 Visit 102: End of sub-study / Day 85 
• 
Check compliance to the IMP and collect PFS-S medication kits and syringes (used and 
unused). 
• 
Collect injection diary and review for content and completeness. 
• 
Report diary feedback on each injection into the e-CRF. 
• 
Collect and assess any PTC using the injection diary. The Investigator will ask the patient 
whether there were any problems associated with the PFS-S – either during drug 
administration or otherwise and will obtain more details as appropriate.

• 
Inquire about and record any adverse events/SAEs related to PTC. 
• 
Prior to the IMP administration (sarilumab in PFS), obtain blood sample for sub-study PK 
(serum sarilumab) and anti-sarilumab antibodies assessment. If the sub-study visit 
coincides with a PK and ADA sampling time point in the main study, no samples are 
required to be obtained for the sub-study. 
• 
Access IVRS/IWRS to register the end of sub-study and to obtain the next scheduled IMP 
(sarilumab in PFS) if the patient returns to the main study. 
10.2 
DEFINITION OF SOURCE DATA 
Besides source data defined in the main study, the injection diary in sub-study is also considered 
as source data. 
10.3 
HANDLING OF PATIENT TEMPORARY OR PERMANENT TREATMENT 
DISCONTINUATION DURING THE SUB-STUDY AND OF PATIENT STUDY 
DISCONTINUATION 
Please refer to the main study as regards handling of patients at the time of temporary or 
permanent treatment discontinuation. 
If the patient chooses to end the participation in the sub-study but to continue in the main study 
they should complete the Visit V102. 
If a patient discontinues the Investigational Medicinal Product (IMP) permanently in LTS11210 
during the sub-study, he/she should complete all procedures planned for V102 in the sub-study as 
well as the end of treatment (EOT) and post treatment follow-up visits in the main study (see 
flowchart in main study Section 1.2). 
10.4 
OBLIGATION OF THE INVESTIGATOR REGARDING SAFETY REPORTING 
10.4.1 Instructions for reporting PTC and adverse events related to PTC 
PTCs may or may not be associated with an adverse event. Any PTC of the PFS-S, whether or not 
associated with an adverse event, must be reported to the sponsor on a PTC form. 
If a PTC is suspected of being associated with the occurrence of an adverse event, the Investigator 
must document the adverse event on an adverse event page in the e-CRF, in addition to 
completing the PTC form. The potential link of the adverse event with the PTC must be specified 
in AE verbatim. 
If a PTC is suspected of being associated with the occurrence of an SAE, the SAE must be 
reported in accordance with the SAE reporting procedures and the Investigator must specify the 
potential link with the PTC in SAE verbatim.

STATISTICAL CONSIDERATIONS 
11.1 
DETERMINATION OF SAMPLE SIZE 
The sample size of this sub-study is based on empirical consideration. No formal sample size 
calculation is performed but an estimate of 120 patients included in this sub-study with up to 
6 injections per patient will provide approximately 680 injections to evaluate PTF during the 
12 weeks of the study assuming 5% of drop-out rate.  
11.2 
DISPOSITION OF PATIENTS 
Enrolled patients are defined as any patient who met the inclusion criteria and none of the 
exclusion criteria, and signed the informed consent. 
11.3 
ANALYSIS POPULATIONS 
The safety population will consist of all enrolled patients who receive at least 1 dose or part of a 
dose of IMP administered via PFS-S during this sub-study. 
Safety analyses will be performed on the safety population.  Patient data will be analyzed 
according to the treatment actually received (200mg q2w PFS-S, 150mg q2w PFS-S, dose 
reduction). 
The PK population will consist of all enrolled patients who receive at least 1 dose of the IMP and 
at least one non-missing serum concentration value. 
11.4 
STATISTICAL METHODS 
The phrase ‘treatment group’ used throughout this section refers to the following device/dose 
groups (200mg q2w PFS-S, 150mg q2w PFS-S, 200mg q2w PFS-S to 150mg q2w PFS-S).  The 
baseline value is defined as original baseline in initial studies. 
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. 
The duration of IMP exposure is defined as: last dose date – first dose date at D1 + 14 days 
(regardless of unplanned intermittent discontinuations).  The duration of exposure to the IMP will 
be summarized for each treatment group by using descriptive statistics such as mean, SD, median, 
minimum, and maximum.

Page 167 
Treatment compliance to the IMP is defined as the actual number of doses received compared to 
the scheduled number of doses during the treatment period.  It is calculated according to the 
following formula: 
100 x total number of doses administered  
nominal number of doses for the duration of exposure 
A given administration will be considered noncompliant if the patient does not take the planned 
dose as required by the protocol.  No imputation will be made for patients with missing or 
incomplete data. 
Treatment compliance during the treatment period will be summarized descriptively (N, mean, 
standard deviation, median, minimum, and maximum).  The percentage of patients with 
compliance <80% will be summarized. 
11.4.2 Analyses of endpoints 
11.4.2.1 Analysis of primary endpoint(s) 
Data will be described for the 12 weeks of this sub-study using the safety population. The primary 
analysis variable is the number of validated PFS-S-associated PTFs during the sub-study. The 
primary analysis will be performed using descriptive statistics. 
11.4.2.2 Analyses of secondary and exploratory endpoints 
Descriptive statistics will be used for continuous variables; discrete variables will be described 
using counts and proportions. Data will be presented by treatment dose group.  
Serum concentrations of functional sarilumab will be summarized using standard descriptive 
statistics such as arithmetic and geometric means, standard deviation (SD), standard error of the 
mean (SEM), coefficient of variation (CV%), minimum, median, and maximum by visit  
For PK parameters Ctrough, estimates and 90% CIs for the ratio of geometric means (Day 85 versus 
Day 1) will be provided using a linear fixed effects model on the log-transformed data. Serum 
trough concentrations of functional sarilumab will be evaluated in patients on stable dose of 
sarilumab at V101 (D1) before using the PFS-S. Patients are considered to be on stable dose of 
sarilumab at V101 (D1) if they receive the same dose of sarilumab without treatment interruption 
for at least 24 weeks in LTS11210 prior to V101. Patients changing dose during the 12 week 
sub-study will be excluded from the Ctrough analyses.

OVERVIEW AND INVESTIGATIONAL PLAN   
This document is the statistical analysis plan (SAP) for the final clinical study report (CSR) and 
guidance for interim analysis reports during the study. 
1.1 
STUDY DESIGN AND RANDOMIZATION 
This is a multicenter, multinational open label long term study, for patients with RA who 
participated and completed EFC11072, ACT11575, EFC10832, SFY13370, and EFC13752 or for 
patients from 12 weeks onward with per protocol defined lack of efficacy from EFC10832. 
Patients, who were randomized in Part B of EFC11072 in a treatment arm subsequently not 
retained following pivotal dose selection, were also eligible for enrollment.  
The 5 previous studies are described briefly below: 
EFC11072:  A randomized, double-blind, placebo-controlled, multi-centre, two-part, dose 
ranging (Part A) and confirmatory (Part B) study with an operationally seamless design, 
evaluating efficacy and safety of sarilumab added to methotrexate (MTX) in patients with active 
rheumatoid arthritis who are inadequate responders to MTX therapy. The study was completed. In 
the dose ranging part of the study (Part A), 5 doses (100 mg weekly [qw], 150 mg qw, 100 mg 
every other week [q2w], 150 mg q2w, and 200 mg q2w) and placebo were tested in combination 
with methotrexate (MTX).  The confirmatory (Phase 3) portion (Part B) which initially had the 
same 6 arms (Cohort 1) and then after Phase 3 dose selection (150 mg q2w and 200 mg q2w) had 
3 arms (Cohort 2: placebo, 150 mg q2w, 200 mg q2w ) for 52-week treatment. In EFC11072 Part 
B, beginning at Week 16, patients with lack of efficacy (defined as less than 20% improvement 
from baseline on 2 consecutive visits in either TJC or SJC, or with any other clear lack of efficacy 
based on Investigator judgment) might have started OL rescue therapy with sarilumab 150 mg qw 
(150 mg qw prior to Phase 3 dose selection; 200 mg q2w after Phase 3 dose selection) in this 
study. These patients were also eligible to enter LTS11210 study if completed the treatment 
period. There were 1283 patients who rolled over to LTS11210. 
ACT11575:  A randomized, double-blind, parallel-group, placebo- and active 
calibrator-controlled study assessing the clinical benefit of sarilumab on top of MTX in patients 
with active RA who have failed previous TNF-α antagonists was terminated by the Sponsor due to 
administrative reasons with only 16 patients enrolled.  There were 7 patients who rolled over to 
LTS11210.  
EFC10832:  A randomized, double-blind, parallel-group, placebo-controlled study assessing the 
efficacy and safety of sarilumab added to DMARD therapy in patients with active rheumatoid 
arthritis (RA) who are inadequate responders or intolerant to tumor necrosis factor-alpha (TNF-α) 
antagonists. Patients are randomized into 3 arms (placebo, 150 mg q2w, 200 mg q2w) with 
24-week treatment. There were 456 patients who rolled over to LTS11210.

SFY13370:  A randomized, double-blind, double-dummy study assessing the safety and 
tolerability of sarilumab and tocilizumab in patients with rheumatoid arthritis who are inadequate 
responders to or intolerant of TNF antagonists. Patients are randomized into 3 arms (Tocilizumab 
IV 4/8 mg/k q4w, 150 mg q2w, 200 mg q2w) with 24-week treatment. There were 168 patients 
who rolled over to LTS11210. 
EFC13752:  An Open-label, Randomized, Parallel Group Study Assessing the Immunogenicity 
and Safety of Sarilumab Administered as Monotherapy in Patients with Active Rheumatoid 
Arthritis. Patients are randomized into 2 arms (150 mg q2w, 200 mg q2w) with 24-week 
treatment. There were 111 patients who rolled over to LTS11210. 
Patients may have been exposed with sarilumab for 12 weeks if they were initially randomized in 
EFC11072 Part A or ACT11575; between 2 and 52 weeks, if initially randomized in EFC11072 
Part B; between 12 and 24 weeks, if initially randomized in EFC10832; or for 24 weeks, if 
initially randomized in SFY13370 and EFC13752. 
Initially in LTS11210, patients received 150 mg of sarilumab SC weekly as the highest dose 
studied in EFC11072 Part A. The reduced dose (due to neutropenia, thrombocytopenia, or an 
increase in liver enzymes [ALT]), was 150 mg q2w.  Once the dose regimens were selected for the 
Phase 3 studies (150 mg q2w and 200 mg q2w), patients already ongoing in the study at the 
highest dose were switched to the new highest sarilumab dose 200 mg q2w, as soon as permitted 
by administrative process.  Patients previously assigned to the reduced dose of 150 mg q2w due to 
safety issue continued to receive 150 mg q2w.   
The duration of the treatment period in the study will be at least 264 weeks, or up to a maximum 
of 516 weeks (except in the UK where the duration of treatment will be 264 weeks) descripted in 
Protocol Amendment 9. However, some patients may complete this study with 260 week 
treatment duration per Protocol Amendment 8 before the approval of Protocol Amendment 9 in 
their countries. The total maximum duration of study participation for a patient may be up to 523 
weeks.  
• 
1-week screening period if applicable  
• 
516-week maximum treatment period in LTS11210 (for the earliest patients enrolled in 
LTS11210 in 2010 if sarilumab is not commercialized by 2020) 
• 
6-week follow up period as required per protocol 
Patients will either enter a 1-week screening period after the EOT visit (Visit 1 in LTS11210) in 
initial studies (for patients from EFC11072 Part A or Part B1 and ACT11575), or enrol directly 
into the treatment period (for patients from EFC11072 Part B2, EFC10832, SFY13370, or 
EFC13752, the EOT visit in the initial study corresponds to the randomization visit, Visit 1/2 in 
LTS11210). 
At Visit 2 or Visit 1/2 (Week 0) after confirmation of eligibility, patients will be administered the 
first open-label dose of sarilumab at the investigational site and will be observed for 30 minutes 
for any medical events. At dosing time points occurring outside site visits, sarilumab can be 
injected by the patients, or by trained caregivers.

Patients will return for the safety follow-up visit 6 weeks after the EOT visit (V49). In case of 
early treatment discontinuation, patients are required to complete the EOT visit (V49) and to 
return for the 6-week safety follow-up visit (Visit 50) as well.  
The study will be considered completed for a patient at the time he/she completes all the 
scheduled procedures. 
An optional 12-week sub-study aiming to evaluate the usability of pre-filled syringe with safety 
system (PFS-S) will be conducted in some countries. Patients enrolled in LTS11210 at selected 
sites in those countries may participate in the PFS-S sub-study from Week 24 of the main study 
after providing written informed consent for the sub-study. However, patients may continue to 
participate in the main trial without participating in the PFS-S sub-study if they wish. Full details 
of the PFS-S sub-study are presented in Appendix K.

a EOT visit and follow up visit 6 weeks later should be completed for all patients at the end of treatment (in patients who complete sarilumab treatment per protocol in countries where sarilumab is commercially 
available the post treatment follow-up visit may be cancelled if the patient initiates treatment with commercial sarilumab during the post treatment follow-up period; however, in this case, a telephone contact must 
be established with the patient to capture all AEs occurring up to the 1st administration of commercial sarilumab). EOT visit may occur when the patients complete 264 weeks of sarilumab treatment from the 
LTS11210, or at any visit thereafter when sarilumab is commercialized in their country, but no later than 2020 when the study will be closed. In case of permanent discontinuation of treatment, the patients will be 
assessed using the procedures normally planned for the EOT visit and the 6 week follow up visit 6 weeks later.  
b From Week 24, patients at limited sites in selected countries may participate in PFS-S sub-study. If the patient enters the sub-study, then the sub-study IMP will be dispensed instead of the main study IMP at the 
entry into sub-study and IMP compliance with sub-study IMP will be reviewed at the end of sub-study. Full details of the sub-study are provided in Appendix R  
c HV: Visit can be home visit or clinic visit to draw and collect the blood sample only for hematology and LFTs using the designated central laboratory.  
d Last treatment visit from the study EFC11072 or ACT11575. Please note that the SF-36 must be completed at the screening visit of the LTS11210 study for patients rolling over from EFC11072 Part A and 
ACT11575 studies.  Please note that the RNA sample must be collected at V2 of the LTS11210 study for patients rolling over from EFC11072. 
e Physical examination to be done at Week 48, 96, 144, 192, 240, 264, 288, 336, 384, 432, 480 and EOT visit.

h After Week 264, only DAS28 components of ACR core set will be assessed (TJC & SJC for 28 joints, patient´s global assessment of disease activity). 
i 
Hematology:  Hemoglobin, hematocrit, red blood cell (RBC) morphology (if blood cell count is abnormal), white blood cell (WBC) with differential, platelets count. For all patients, a CBC test must be performed 
before or at Visit 3 (using either designated central lab or a local laboratory facility), but not earlier than the 12th day after the first dose of IMP administration in order to confirm that the neutrophil count and platelet 
count are not within the protocol-defined limits for temporary or permanent discontinuation of study drug. 
j 
Liver Function Tests (LFTs): Prothrombin Time (PT), Albumin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total bilirubin, conjugated bilirubin, unconjugated 
bilirubin. PT is NOT required at any visit after Week 264. 
k Lipids (fasting): Total cholesterol (TC), High-Density Lipoprotein (HDL) cholesterol, Low-Density Lipoprotein (LDL) cholesterol, triglycerides, Apolipoprotein A, and Apolipoprotein B. After Week 264, lipids (excluding 
Apolipoprotein A, and Apolipoprotein B ) will only be assessed at Weeks 288, 336, 384, 432, 480 (including EOT if EOT is after Week 264)  
l 
Clinical chemistry (fasting): fasting glucose, total proteins, calcium, sodium, potassium, Lactate Dehydrogenase, (LDH), urea nitrogen and creatinine. Creatinine clearance will be calculated during the study if 
clinical indicated.  
m ANA titer will be done at screening, at Week 48, 96, 144, 192, 240, 264, 288, 336, 384, 432, 480 and EOT visit or sooner if clinical indicated (Anti-ds-DNA only if ANA titer is >1:160) 
n Dipstick urinalysis for:  specific gravity, pH, glucose, blood, ketones, proteins, bilirubin, urobilinogen, nitrite, leukocytes. If any parameter is abnormal, a urinalysis sample should be sent to central laboratory for 
testing. If positive for proteins, microscopic analysis will be performed by central laboratory. 
o After Visit 7 (Week 12) between study visits the patient will have a urine pregnancy test at home on a monthly basis.  Patients will be given sufficient urine pregnancy kits to take home at each successive visit for 
monthly testing up until the final treatment visit. When the testing coincides with a clinical visit as indicated in the flow chart, the results should be reported in the eCRF. No pregnancy test kits will be dispensed at 
EOT.  
p ECG to be done at Weeks 48, 96, 144, 192, 240, 264 or EOT; No ECG will be done after Week 264 including EOT if EOT is after Week 264. 
q Rheumatoid factor only at baseline Visit 2 (Week 0) and at Weeks 48, 96, 144, 192, 240, 264 or EOT. No Rheumatoid factor will be assessed after Week 264 including EOT if EOT is after Week 264. 
r 
If throughout the study a serious adverse event (SAE) occurs in a patient, blood samples should be collected for sarilumab at or near the onset and completion of the occurrence of the event, if possible.  The exact 
date of sample collection and last dose must be recorded on the e-CRF.  
s Serum sample for biomarkers to be collected at screening (ie, the last treatment visit from the EFC11072 or ACT11575), Week 2, Week 12, and Week 48. 
t 
Blood sample for RNA to be collected at Week 0 (baseline, prior to administration of study drug) and Week 2 (at site visit only; cancel RNA collection if home visit). 
u Deleted. 
v Samples for IL-6 to be collected at Screening (ie the last treatment visit from EFC11072 or ACT11575) and at V4 (Week 4), V7 (Week 12), V8 (Week 24), V9 (Week 36), and V10 (Week 48).

a EOT visit and follow up visit 6 weeks later should be completed for all patients at the end of treatment (in patients who complete sarilumab treatment per protocol in countries where sarilumab is commercially 
available the post treatment follow-up visit may be cancelled if the patient initiates treatment with commercial sarilumab during the post treatment follow-up period; however, in this case, a telephone contact must 
be established with the patient to capture all AEs occurring up to the 1st administration of commercial sarilumab). EOT visit may occur when the patients complete 264 weeks of sarilumab treatment from 
LTS11210, or any visit thereafter when sarilumab is commercialized in their country, but no later than 2020 when the study will be closed. (In UK, the duration of treatment will be 264 weeks from the first study 
drug administration in LTS11210).  In case of permanent discontinuation of treatment, the patients will be assessed using the procedures normally planned for the EOT visit and the 6 week follow up visit 6 weeks 
later.  
b From Week 24, patients at limited sites in selected countries may participate in PFS-S sub-study. If the patient enters the sub-study, then the sub-study IMP will be dispensed instead of the main study IMP at the 
entry into sub-study and IMP compliance with sub-study IMP will be reviewed at the end of sub-study. Full details of the sub-study are provided in Appendix R  
c HV: Visit can be home visit or clinic visit to draw and collect the blood sample only for hematology and LFTs using the designated central laboratory.

treatment groups in the respective previous studies (placebo, 150 mg q2w, 200 mg q2w, 
other sarilumab, and active control treatment groups) as well as overall in LTS11210, 
based on the reported adverse events, clinical laboratory evaluations, vital signs, and 
12-lead ECGs  
• 
Updated analysis treatment groups: The efficacy analyses will be done descriptively on the 
safety population by the originally randomized treatment groups as assigned in the 
respective previous studies (placebo, 150 mg q2w, 200 mg q2w, other sarilumab, and

STATISTICAL AND ANALYTICAL PROCEDURES 
Below are general rules for the analysis procedure. 
For patients from EFC11072, ACT11575, EFC10832 and SFY13370 with sarilumab + DMARD 
therapy in the initial and current studies, all analyses will be performed based on previous 
treatment prior to enrollment into LTS11210 (placebo, sarilumab 150 mg q2w, sarilumab 200 mg 
q2w, other sarilumab (non-selected) doses, and active control treatment) as well as overall in 
LTS11210, unless otherwise specified. Interim analyses may be performed based on overall 
sarilumab +DMARD therapy only. 
For patients from EFC13752 with sarilumab monotherapy in the initial and current studies, all 
analyses will be performed based on previous treatment prior to enrollment into LTS11210 
(sarilumab 150 mg q2w, sarilumab 200 mg q2w) as well as overall in LTS11210, unless otherwise 
specified. Interim analyses may be performed based on overall sarilumab monotheraphy only. 
Data analysis results will be presented by sarilumab +DMARD therapy and sarilumab 
monotherapy in LTS11210 separately. All analyses will be performed in observed cases unless 
otherwise specified. 
Data analyses for the PFS-S sub-study will be described in Appendix K. 
2.1 
ANALYSIS ENDPOINTS 
2.1.1 Demographic and baseline characteristics 
For patients who roll over to LTS11210, new demographic data are collected in LTS11210, but 
some baseline characteristic information (such as height, time since diagnosis of RA, rheumatoid  
factor and prior biologic use) is not collected in LTS11210. This missed information will be 
captured from the previous study databases.   
All baseline safety and efficacy parameters (apart from the ones listed below) are presented along 
with the on-treatment summary statistics in the safety and efficacy sections (Section 2.4.4 and 
Section 2.4.5). 
Demographic characteristics 
The following demographic characteristics will be summarized: 
• 
Gender (Male, Female)  
• 
Race (Caucasian/white, Black, Asian/Oriental, other) 
• 
Ethnicity (Hispanic, Not Hispanic) 
•

Height (cm) 
• 
Body mass index (BMI, kg/m2) 
• 
BMI group (<25, ≥25 and < 30, ≥30 kg/m2). 
Medical or surgical history 
The medical and surgical history data were collected in the previous studies.  
This information will be coded to a “Lower 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. 
Disease characteristics at baseline   
The following baseline disease characteristics will be summarized: 
• 
Time since diagnosis of RA (years) 
• 
Rheumatoid  factor (Positive: ≥1 IU/mL, negative: <1 IU/mL) 
• 
Prior biologic DMARD use for RA  
• 
Smoking history 
• 
Alcohol use  
In addition, the summary of baseline values for clinical signs and symptoms and quality of life 
assessments will be presented in the summary tables for these data. 
Any technical details related to computation, dates, imputation for missing dates are described in 
Section 2.5.  
2.1.2 Prior or concomitant medications  
All medications taken at any time during LTS11210 period, from the enrollment to the end of the 
follow-up period, including those ongoing at study start, are to be reported in the CRF pages. 
All medications will be coded using the World Health Organization-Drug Dictionary (WHO-DD) 
using version currently in effect at sanofi at the time of database lock.  
Concomitant medications are any treatments received by the patient concomitantly to the/any IMP, 
from the first IMP intake in LTS11210 to the end of the follow-up period.

Prior medications are those the patient used prior to first IMP intake in LTS11210. Prior 
medications can be discontinued before first dosing or can be ongoing during treatment phase. The 
data before enrollment were reported in the previous study reports. However the data from 
enrollment up to the time of first IMP intake will be reported in LTS11210 database. 
Any technical details related to computation, dates, imputation for missing dates are described in 
Section 2.5. 
2.1.3 Safety endpoints 
The primary endpoint is the incidence of adverse events.  The safety analysis will be based on the 
reported adverse events (AEs) and other safety information, such as clinical laboratory data, vital 
signs and ECG. 
Observation period  
The observation period will be divided into 4 epochs: 
• 
The SCREENING epoch is defined as beginning with the last visit in the previous studies 
to the first dose of IMP in LTS11210  
• 
The TREATMENT epoch is defined as the time from first dose of IMP in LTS11210 to 
last dose of IMP + 13 days (6 days for patients receiving weekly injections only ) 
• 
The FOLLOW-UP epoch is defined as the time from the end of TREATMENT epoch to 
last dose of IMP + 60 days 
• 
The POST-STUDY epoch is defined as the time after the last dose of IMP + 60 days  
The rational of having “last dose of IMP + 60 days” as the end of follow-up epoch is to capture the 
events observed within an approximately 5 half-lives of the last IMP. The treatment-emergent AE 
(TEAE) period will include both TREATMENT and FOLLOW-UP epochs.  
Please note: Not all the patients will have all 4 epochs. For example, if a patient died on the 7th 
day after the last dose of IMP, his/her TREATMENT epoch will be from the first dose of IMP to 
his/her death date and will have no FOLLOW-UP or POST-STUDY epoch; if a patient had his 
last visit (i.e. follow-up visit 29) on the 50th day after the last dose of IMP and have no AE 
reported after this date, his/her FOLLOW-UP epoch will be ended on last dose of IMP+50 days 
and will have no POST-STUDY epoch. 
2.1.3.1 Adverse events variables 
Adverse event observation period  
• 
Pre-treatment AEs are AEs that developed or worsened or became serious from the signed 
informed consent date up to first dose of IMP in LTS11210. The ongoing AEs from 
previous studies filled out on AE switch CRF pages are also considered as pre-treatment 
AEs

post-study period 
All AEs (including SAEs and AESIs and ongoing AEs from previous studies filled out on AE 
switch CRF pages) will be coded to a “Lowest Level Term (LLT)”, “Preferred Term (PT)”, “High 
Level term (HLT)”, “High Group Level 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.

out on AE switch CRF pages) will be recorded from the time of signed informed consent until the 
end of the study.  
Adverse event of special interest (AESI)  
AESIs will be flagged in the database using search criteria.  All AEs captured on the general AE 
form, the ALT increase form, the suspected infection event form, the diverticulitis or 
gastrointestinal ulceration form, or the neurological event form will be searched.  The list of the 
AESIs with the search criteria are provided below:

Note that TJC and SJC (both based on 28 joints), patient’s global assessment of disease activity 
and hs-CRP will still be assessed after Week 264 to calculate DAS28. 
As mentioned before, the baseline value for efficacy parameters is the original baseline from the 
previous study databases for patients who rolled over to LTS11210.  
A) ACR20 response over time 
To be classified as an ACR20 Responder, a patient must achieve 20% improvement in the 
Tender joint count (68 joints) and the Swollen joint count (66 joints), as well as 20% 
improvement in at least 3 of the following 5 assessments: 
• 
Levels of an acute phase reactant (CRP level) 
• 
Patient’s assessment of pain based on the 0 – 100mm Visual Analogue Scale (VAS) 
• 
Patient’s global assessment of disease activity based on the VAS 
• 
Physician’s global assessment of disease activity based on the VAS 
• 
Patient’s assessment of physical function based on the HAQ_DI 
The 7 ACR components assessing the signs and symptoms of RA are measured as follows  
a) Tender Joint Count (TJC) 
A total of 68 joints will be assessed for tenderness. The 68 joints to be examined for 
tenderness are: temporomandibular (n=2), sternoclavicular (n=2), acromioclavicular (n=2), 
shoulder (n=2), elbow (n=2), wrist (n=2), metacarpophalageal (n=10), interphalangeal of 
thumb (n=2), distal interphalangeal (n=8), proximal interphalangeal (n=8), hip (n=2), knee 
(n=2), ankle mortise (n=2), ankle tarsus (n=2), metatarsophalangeal (n=10),interphalangeal of 
great toe (n=2), and proximal/distal interphalangeal of the toes (n=8).  
A formal count of the joints will be performed by a trained independent assessor. Joint 
tenderness is defined as pain induced by the pressure of the joints, exerted by the assessor’s 
thumb and index finger. The assessor will classify each joint as painful yes/no and swollen 
yes/no. A score of 0/1 will be given to each tender joint with 0 representing no pain and 1 
representing pain. The tender joint count ranges from 0 to 68 where 0 is considered the best 
and 68 the worst.

b) Swollen Joint Count (SJC) 
The 66 joints to be examined for swelling are the same as those examined for tenderness, 
except the hip joints are not included.  
A formal count of the joints will be performed by a trained independent assessor. The assessor 
will classify each joint as swollen yes/no. A score of 0/1 will be given to each swollen joint 
with 0 representing no swollen and 1 representing a swollen joint. The swollen joint count 
ranges from 0 to 66 where 0 is considered the best and 66 the worst. 
c) Physician’s Global Assessments of Disease Activity 
Physician’s global assessments of the patient’s current disease activity will be accessed on an 
anchored 100 mm horizontal VAS where 0 is considered the best disease activity (no disease 
activity) and 100 the worst (most disease activity). 
d) Patient’s Global Assessments of Disease Activity 
Patient’s global assessments of their current disease activity will be rated on an anchored 
100 mm horizontal VAS where 0 is considered the best disease activity (no disease activity) 
and 100 the worst (most disease activity). 
e) Patient’s Assessment of Pain 
Patients will be requested to indicate their pain intensity due to their RA using a 100 mm 
horizontal VAS where 0 is considered “No pain” and 100 “the worst pain you can imagine”. 
f) Patient’s Assessment of Physical function – Health Assessment Questionnaire Disease 
Index (HAQ-DI) 
The HAQ-DI is a standardized questionnaire developed for use in RA. The HAQ-DI, with the 
past week as the time frame, focuses on whether the respondent “is able to…” do the activity 
and covers 8  categories in 20 items: dressing and grooming, arising, eating, walking, hygiene, 
reach, grip and activities, for which there are at least 2 questions by category. The 4  responses 
for the HAQ-DI questions are graded as follows: without any difficulty = 0; with some 
difficulty = 1; with much difficulty = 2; and unable to do = 3. To calculate the Standard 
HAQ-DI Score (With Aids/Devices), there are 3 steps   
1. Sum the 8 category scores by using the highest sub-category score from each category. 
- 
For example, in the category ARISING there are 3 sub-category items. A patient who 
responds with a 1, 2, and 0, respectively, results in category score of 2. 
2. Adjust for use of aids/devices and/or help from another person when indicated. 
- 
Adjust the score for a category by increasing a 0 or a 1 to a 2.

3. Divide the summed category scores by the number of categories answered (must be a 
minimum of 6) to obtain a HAQ-DI score of 0-3 (3=worst functioning). 
A HAQ-DI score cannot be calculated validly when there are scores for less than 6 of the 8 
categories. HAQ-DI scoring ranges between 0 and 3. A high HAQ-DI score has been found to 
be a strong predictor of morbidity and mortality in RA.  
g) The level of an acute phase reactant measured by CRP 
High sensitivity CRP will be assessed centrally. Since CRP levels are directly correlated with 
Interleukin 6 receptor (IL6-R) activity, it is expected that active dose regimens will have a 
dramatic lowering effect on CRP levels. 
The ACR components are further described in

Tender joints count (based on 28 joints: shoulder (n=2), elbow (n=2), wrist (n=2), 
metacarpophalageal (n=10), interphalangeal of thumb (n=2), proximal interphalangeal 
(n=8), knee (n=2))

• 
General health (GH) or patient’s global assessment of disease activity based on VAS (mm) 
assessed from the ACR questionnaire 
• 
Marker of inflammation here assessed by the hs-CRP ( mg/L). 
It is a continuous measure allowing for measurement of absolute change in disease burden and 
percentage improvement. It has been extensively validated for its use in clinical trials and accepted 
by health authorities. Using this data, the DAS28 can be calculated using the following formula: 
DAS28-CRP  = 0.56 x 
TJC
28
 + 0.28 x 
SJC
28
 + 0.36 x Log(CRP+1) + 0.014 x GH + 0.96, 
Where 28TJC and 28SJC are the tender and swollen joint counts from 28 joints and GH is the 
patient’s global assessment of disease activity and CRP is in mg/L.  
DAS28-CRP provides a number on a scale from 0 to 10 indicating the current activity of the RA. 
DAS28 –CRP will be considered as missing if one of the components is missing. 
F) DAS28 remission over time 
DAS28 Remission is the event of having a DAS28-CRP score <2.6. 
G) European League Against Rheumatism (EULAR) response over time 
The European League Against Rheumatism (EULAR) response criteria combine the DAS28 score 
at the time of evaluation with the change in DAS28 score between 2 time points. The EULAR 
response criteria are defined as: 
• 
Good response = The event of having an improvement of >1.2 and a present DAS28-CRP 
score ≤3.2. 
• 
Moderate response = The event of having either an improvement of >0.6 to ≤1.2 and a 
present DAS28-CRP score ≤5.1, OR, having an improvement of >1.2 and a present 
DAS28-CRP score >3.2. 
• 
No response = The event of having either an improvement of ≤0.6, OR, having an 
improvement of >0.6 to ≤1.2 and a present DAS28-CRP score >5.1.

H) Change in van der Heijde modified total Sharp score over time 
X-ray data will be collected for patients from EFC11072 Part B Cohort 2 and Cohort 1 selected 
dose arms only. The degree of joint damage will be assessed using the van der Heijde modified 
total Sharp score (mTSS). This methodology quantifies the extent of bone erosions for 44 joints 
and joint space narrowing for 42 joints, with higher scores representing greater damage. The van 
der Heijde mTSS at a time point is the sum of the scores from both the erosion score and the joint 
space narrowing score, for a maximum score of 448. 
Erosion score 
The joint erosion score is a summary of erosion severity in 32 joints of the hands and 12 joints of 
the feet. Each joint is scored, according to the surface area involved, from 0 to 5 for hand joints 
and 0 to 10 for the joints of the foot. The maximum erosion score (5 for the hand and 10 for the 
foot) indicates extensive loss of bone from more than one half of the articulating bone. A score of 
0 in either the hand or foot indicates no erosion. The maximum erosion score is 280 (160 in the 
hands and 120 in the feet) for a time point. 
Joint space narrowing score 
The joint space narrowing (JSN) score summarizes the severity of JSN in 30 joints of the hands 
and 12 joints of the feet. Assessment of JSN for each hand (15 joints per hand) and foot (6 joints 
per foot), including subluxation, is scored from 0 to 4, with 0 indicating no/normal JSN and 4 
indicating complete loss of joint space, bony ankylosis or luxation. Thus, the maximum JSN score 
is 168 at a time point. 
X-ray data reading 
Campaign 1 
X-rays read in Campaign 1 will include baseline and EOT (or last available visit) from EFC11072, 
Week 48 and any unscheduled visits between Week 0 and Week 48 in LTS11210. Two primary 
readers and an adjudicator will perform reading of data up to Week 48 in LTS11210 (see details in 
Appendix D). The X-rays at baseline and Year 1 (EOT or last available visit in EFC11072) will be 
reread.

The linear extrapolation method will be used to impute missing modified total Sharp score, 
erosion score, or joint space narrowing score at Week 48 in LTS11210 from Campaign 1 data for 
patients who have EOT (or last available data) in EFC11072 and any unscheduled visit data 
between Week 0 and Week 48 in LTS11210. In the linear extrapolation method, for example, the 
missing modified total Sharp score at Week 48 is imputed according to the following formula: 
Week 48 modified total Sharp score = EOT score in EFC11072 + 336*(modified total Sharp 
score of the last measurement in LTS11210 – EOT score in EFC11072)/(date of last measurement 
in LTS11210 – date of EOT visit in EFC11072).  
Campaign 2 
X-rays in Campaign 2 will include baseline from EFC11072, Weeks 48 and 96, and any 
unscheduled visits between Week 48 and Week 96 in LTS11210. The linear extrapolation method 
will be used to impute missing the modified total Sharp score, erosion score, or joint space 
narrowing score at Week 96. Similarly, the missing modified total Sharp scores at Week 96 are 
imputed by the linear extrapolation method according to the following formula: 
Week 96 modified total Sharp score = Week 48 score + 336*(modified total Sharp score of the 
last measurement – Week 48 score)/(date of last measurement – date of Week 48 measurement),  
Campaign 3 
X-rays in Campaign 3 will include baseline from EFC11072, Weeks 96, 144 and 192 (or EOT), 
and any unscheduled visits between Week 96 and Week 192 (or EOT) in LTS11210. The linear 
extrapolation method will be used to impute missing the modified total Sharp score, erosion score, 
or joint space narrowing score at Weeks 144 and 192 in LTS11210 based on Campaign 3 data. 
Similarly, the missing modified total Sharp scores at Week 144 and Week 192 in LTS11210 are 
imputed by the linear extrapolation method according to the following formula: 
Week 144 modified total Sharp score = Week 96 score+ 336*(modified total Sharp score of the 
last measurement – Week 96 score)/(date of last measurement – date of Week 96 measurement),  
Week 192 modified total Sharp score = Week 96 score + 672*(modified total Sharp score of the 
last measurement – Week 96 score)/(date of last measurement – date of Week 96 measurement),  
Where EOT visit for X-ray in LTS11210 will be prior to  Week 192 if a patient discontinues the 
study prior to Week 192. 
I) Incidence of radiographic progression of the van der Heijde modified total Sharp 
score over time 
Note that missing modified total Sharp scores are imputed by the linear extrapolation method. And 
then a change from the baseline in the modified total SHARP score will be calculated.  A change 
from the baseline in the modified total SHARP scores of ≤ 0 is considered as no progression.

J) Change from baseline in HAQ-DI 
The HAQ-DI is composed of 8 categories as follows: dressing and grooming, arising, eating, 
walking, hygiene, reach, grip and activities, for which there are at least 2 questions by category. 
The patient will be asked to score how difficult he/she feels it is to perform such activities using a 
0 to 3 scoring (0=without any difficulty, 1=with some difficulty, 2=with much difficulty and 
3=unable to do). If the patient is using assistance for any of these activities, scoring may be 
adjusted. For each category, the highest score given for one of the question is attributed to the 
category. The total score is the sum of all categories’ scores divided by the number of answered 
categories (at least 3 categories should be answered). 
2.1.5 Pharmacokinetic and immunogenicity variables 
Immunogenicity (anti-sarilumab antibody) and pharmacokinetic blood samples (trough 
concentrations) will be collected according to the study flow chart. Pharmacokinetic samples will 
also be collected at or near the onset and completion of the occurrence of a serious adverse event. 
Note that there are some missing data after Week 48 since pharmacokinetic evaluation were added 
after Week 48 per Protocol Amendment 8 and by that time some patients already reach more than 
48 weeks of treatment. 
At each sample time the result of the ADA assay will be categorized as either positive or negative, 
and in the case of a positive result will be further characterized as either neutralizing or 
non-neutralizing. 
2.1.6 Pharmacodynamic/genomics endpoints 
Serum concentrations of IL-6 will be assessed according to the study flow chart. 
2.1.7 Quality-of-life endpoints 
SF-36 V2 (for patients from EFC11072, ACT11575 and EFC10832 only) 
The SF-36 version 2 is a multi-purpose, short-form health survey with 36 questions.  It yields 
scores for 8 domains (Physical Functioning, Role-Physical, Bodily pain, General health, Vitality, 
Social Functioning, Role-Emotional, and Mental Health, each scale is scored from 0 to 100 where 
higher scores indicate better health and well-being), as well as 2 summary measures of physical 
and mental health: the Physical Component Summary and Mental Component Summary (1). 
The scoring process is summarized below: 
1. Enter item response data 
2. Recode item response values 
3. Determine health domain scale raw scores.  
4. Transform health domain scale raw scores to 0-100 scores.

MCS and PCS derived from the eight scales 
The score of each of the 36 items is collected in CRF.  Appendix I provides the SAS code to 
calculate the 8 scales, the 2 summary measure scores and standardized summary scores. 
The PCS and MCS summary measure scores will be computed if at least 50% of the component 
scales are available. The scale scores will be computed if at least 50% of items are available 
within the corresponding scale. The missing items will be imputed by the mean of available items. 
Change from baseline in SF-36 scores (physical component summary score and mental component 
summary score as well as the eight domains) will be analyzed. 
2.1.8 Health economic endpoints 
WPAI (for patients from EFC11072 and ACT11575 only) 
Work Productivity and Activity Impairment (WPAI) will be assessed. WPAI outcomes are 
expressed as impairment percentages, with higher numbers indicating greater impairment and less 
productivity, ie., worse outcomes, as follows:  
• 
Q1 = currently employed 
• 
Q2 = hours missed due to specified problem (RA) 
• 
Q3 = hours missed other reasons 
• 
Q4 = hours actually worked 
• 
Q5 = degree problem affected productivity while working 
• 
Q6 = degree problem affected regular activities Scores

Scores will be expressed in percentages. 
• 
Percent work time missed due to problem (RA): 100*Q2/(Q2+Q4) 
• 
Percent impairment while working due to problem: 10*Q5 
• 
Percent activity impairment due to problem: 10*Q6 
• 
Percent overall work impairment due to problem (RA):  
100*Q2/(Q2+Q4)+100*[(1-Q2/(Q2+Q4))*(Q5/10)] 
When deriving the 4 WPAI scores, missing data will be handled using the following rules. 
• 
Percent work time missed due to problem (RA): The score will be missing if either Q2 or 
Q4 is missing. 
• 
Percent impairment while working due to problem: The score will be missing if Q5 is 
missing. 
• 
Percent activity impairment due to problems: The score will be missing if Q6 is missing. 
Percent overall work impairment due to problem (RA): The score will be missing if either 
percent work time missed due to problem (RA) is missing or percent impairment while 
working due to problem is missing. 
FACIT-Fatigue (for patients from EFC11072, ACT11575 and EFC10832 only) 
The Functional Assessment of Chronic Illness Therapy Fatigue scale (FACIT-Fatigue) will be 
used to assess fatigue. The FACIT-Fatigue is a 13-item questionnaire rated 0 to 4 originally 
developed to measure fatigue in patients with cancer and is widely used in RA patients to 
demonstrate good consistency and sensitivity to change. The patient will be asked to answer 13 
questions rated 0 to 4 (0=not at all, 1=a little bit, 2=some what, 3=quite a bit, 4=very much). The 
fatigue scale has 13 items, with 52 as the highest possible score. A higher score in the fatigue scale 
corresponds to a lower level of fatigue and indicates better Quality of Life. 
To calculate the FACIT-fatigue score, the response scores on negatively phrased questions are 
reversed and then the 13 item responses are added. Eleven items with responses have their scores 
reversed (item score = 4 – response, if the response is not missing), and two items (items 7-8) 
have their responses unchanged (Appendix F). All items are added so that higher scores 
correspond to less fatigue. In cases where individual questions are skipped, scores are prorated 
using the average of other answers in the scale.  
FACIT-Fatigue = 13*[sum(reversed items)+sum(items 7-8)]/number of answered items 
Sleep questionnaire (for patients from EFC11072 and ACT11575 only) 
RA like other chronic illness is associated with sleep disturbances. Sleep disturbances is linked to 
pain, mood and disease activity. The effect of sarilumab on pain will be assessed on a sleep 
questionnaire VAS scale ranges from 0 (sleep is not a problem) to 100 (sleep is a major problem).

WPS-RA (for patients from EFC10832 only) 
The rheumatoid arthritis-work productivity survey (WPS-RA) is a validated questionnaire that 
evaluates productivity limitations within work and within home associated with RA over the 
previous month. The questionnaire is interviewer-administered and is based on patient self-report. 
It contains 9 questions addressing employment status (1 item), productivity at work (3 items) and 
within and outside the home (5 items) (Appendix H). 
2.2 
DISPOSITION OF PATIENTS 
This section describes patient disposition for both patient study status and the patient analysis 
populations for LTS11210 only, unless otherwise specified. 
• 
All screened patients are defined as those patients who signed the informed consent. 
• 
All enrolled patients are defined as all patients with signed informed consent who met the 
eligibility criteria to enter into LTS11210.   
• 
The Safety population consists of all enrolled patients who received at least one dose of the 
LTS11210 study medication. 
For patient study status, the total number of patients for each one of the following categories will 
be presented using a summary table: 
• 
All screened patients (informed consent signed) 
• 
Screen failure patients and reasons for screen failure (not eligible per eligible CRF page) 
• 
Non-enrolled but treated patients 
• 
All enrolled patients by previous studies  
• 
Enrolled but not treated patients 
• 
Enrolled and treated patients 
• 
Patients who had dose reductions 
• 
Patients who discontinued study treatment by main reason for permanent treatment 
discontinuation 
• 
Status at last study contact 
For all categories of patients (except for the screened and non-enrolled categories), percentages 
will be calculated using the total of all enrolled patients as the denominator.  Reasons and time to 
treatment discontinuation will be supplied in tables giving numbers and percentages.  This 
summary will be further sub-grouped by region and by prior biological use. 
A patient is considered as lost to follow-up at the end of the study if he/she is not assessed at the 
last protocol planned visit.

The analysis populations for safety, efficacy and PK will be summarized in a table by patient 
counts on the enrolled patients. 
• 
Safety population (for safety and efficacy analyses), 
• 
PK population. 
 
2.2.1 Randomization and drug dispensing irregularities 
There is no randomization procedure in LTS11210. Drug dispensing irregularities occur 
whenever: 
• 
A patient is dispensed an IMP kit not allocated by the IVRS, such as, a) a patient at any 
time in  the study is dispensed a different treatment kit than as assigned (which may or may 
not contain the correct assigned IMP), or b) a non-screened patient is treated with study 
medication reserved for enrolled patients. 
Drug dispensing irregularities will be monitored throughout the study and reviewed on an ongoing 
basis.  
All drug dispensing irregularities will be documented.  If the number of irregularities is large 
enough to make a tabular summary useful, the irregularities will be categorized and summarized 
among all patients (number and percentages). 
Drug dispensing irregularities to be prospectively identified include but are not limited to:

ANALYSIS POPULATIONS 
The primary analysis population is the safety population.  All safety analyses and efficacy analyses 
will be performed based on the safety population.  
The patients who enroll into LTS11210 study but are not treated will be reported separately, and 
these patients will not be in the safety population for this study.

2.3.1 Safety populations 
Safety population is defined as all enrolled patients who have received at least one dose of the 
study treatment in LTS11210.   
All analyses will be performed on the safety population based on previous treatment prior to 
enrollment into LTS11210. This will allow for assessment of any differences between treatment 
groups based on previous treatment. 
2.3.2 Efficacy population 
The efficacy analysis population is the same as safety population. 
Efficacy analyses will be performed on the safety population based on previous treatment prior to 
enrollment into LTS11210.  This will allow for assessment of the efficacy improvement if it is 
related to the different original treatments. Note that X-ray data will be collected for patients from 
EFC11072 Part B Cohort 2 and Cohort 1 selected dose arms only.  
2.3.3 Pharmacokinetics and immunogenicity population 
The PK population will consist of all patients in the safety population with at least one post-dose 
non-missing plasma concentration value. The ADA population will consist of all patients in the 
safety population with at least one post-dose, evaluable ADA sample. Patients will be analyzed 
according to the treatment actually received. 
2.4 
STATISTICAL METHODS 
2.4.1 Demographics and baseline characteristics 
Only patients enrolled and treated in LTS11210 will be summarized on demographic and baseline 
characteristic data.  
Continuous data will be summarized using number of available data, mean, SD, median, 
minimum, and maximum. Categorical and ordinal data will be summarized using number and 
percentage of patients. 
Parameters described in Section 2.1.1 will be summarized based on the safety population using 
descriptive statistics.  
Medical and surgical history will be summarized on the safety population by system organ class 
(SOC) and preferred term (PT) sorted by internationally agreed order of SOC and by the 
decreasing frequency of PT within SOC. 
No specific description of the safety/efficacy parameters will be provided at baseline. If relevant, 
the baseline values will be described along with each safety/efficacy analysis.

2.4.2 Prior or concomitant medications  
Prior medications are those the patients used prior to first IMP intake in LTS11210. The data 
before enrollment were collected and reported in the previous studies. However the data from 
enrollment up to the time of first IMP intake will be reported in LTS11210 database.  
Prior and concomitant medications in LTS11210 will be presented based on the enrolled 
population.  
Medications will be summarized by treatment received according to the WHO-DD dictionary, 
considering the first digit of the ATC class (anatomic category) and the first three digits of the 
ATC class (therapeutic category). All ATC codes corresponding to a medication will be 
summarized. Patients will be counted once in each ATC categories (anatomic or therapeutic) 
linked to the medication, therefore, patients may be counted several times for the same 
medication. In addition, the summaries for concomitant DMARDs (MTX, non-MTX DMARDs), 
folic acid, NSAIDs, corticosteroids, and lipid modifying agents will also be provided. 
The tables for concomitant medications will be sorted by decreasing frequency of anatomic 
category followed by all other therapeutic classes. In case of equal frequency regarding anatomic 
categories (respectively therapeutic categories), alphabetical order will be used. 
2.4.3 Extent of investigational medicinal product exposure and compliance  
The extent of IMP exposure and compliance will be presented on the safety population. In 
addition, the extent of IMP exposure will also be assessed and summarized by actual treatment 
received (150 mg qw, 200 mg q2w, 150 mg q2w) in LTS11210. 
Dose reduction 
Per study design, patients can reduce dose due to safety consideration. These patients who were 
switched to a lower dose regimen (ie. 150 mg q2w) due to safety consideration, not administration 
errors, will be listed and/or summarized separately. There are 3 type cases of dose reduction: 
initial 150 mg qw reduced to 150 mg q2w, initial 200 mg q2w reduced to 150 mg q2w, initial 
150 mg qw switched to 200 mg q2w (per Protocol Amendment 3) then reduced to 150 mg q2w. 
The reasons for dose reduction are collected and the summary will be provided accordingly. In 
addition, time to first dose reduction will be analyzed using Kaplan-Meier method for each type of 
dose reduction by previous treatment prior to enrollment into LTS11210. The maximal grade of 
neutropenia and maximal grade of ALT elevation after dose reduction will be summarized for 
each type of dose reduction by dose reduction reason. Treatment discontinuation after dose 
reduction, such as discontinuation reason and time from dose reduction date to treatment 
discontinuation date, will also be analyzed by summary and Kaplan-Meier plot. Detailed analyses 
will be performed in the integrated summary of safety (ISS) and the final CSR.

2.4.3.1 Extent of investigational medicinal product exposure 
The extent of IMP exposure will be assessed by the duration of IMP exposure and actual dose 
information. 
Extend of IMP exposure 
Due to a global switch to the pivotal dose or a dose reduction to a lower pivotal dose if it applies, 
each patient may receive multiple doses. Hence the duration of IMP exposure will be calculated 
under ‘sarilumab’ treatment regardless what doses the patient received during LTS11210.   
For patients receiving weekly injections at the time of last injection, duration of IMP exposure is 
defined as:  [Date of last injection of the study medication in LTS11210] – [Date of first injection 
of the study medication in LTS11210] + 7 day, regardless of unplanned intermittent 
discontinuations (see Section 2.5.3 for calculation in case of missing or incomplete data).  
For patients receiving biweekly injections at the time of last injection, duration of IMP exposure is 
defined as:  [Date of last injection of the study medication in LTS11210] – [Date of first injection 
of the study medication in LTS11210] + 14 day, regardless of unplanned intermittent 
discontinuations (see Section 2.5.3 for calculation in case of missing or incomplete data).  
Duration of each dose 
Period for each treatment dose received is calculated as the days from the starting (injection) date 
of that dose regimen to one day before the starting date of the following dose regimen or to the 
end (injection) date of the same dose + 14 days (7 days for patients receiving weekly injections 
only) if that is the last dose regimen in the study. Duration of IMP exposure will be summarized 
descriptively as a quantitative variable (number, Mean, SD, Median, Minimum, and Maximum). 
In addition, duration of treatment exposure will also be summarized categorically by counts and 
percentages for each of the following categories and cumulatively according to these categories: 
≤4 weeks, >4 and ≤12 weeks, >12 and ≤24 weeks, > 24 and ≤48 weeks, > 48 and ≤72 weeks, 
>72 and ≤96 weeks, and at 24-week intervals through the end of the study. 
 Additionally, the cumulative duration of treatment exposure, defined as the sum of patients’ 
duration of treatment exposure and expressed in patient years, will be provided. 
2.4.3.2 Compliance 
A given administration will be considered as non-compliant 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. 
Percentage of compliance for a patient will be defined as the number of administrations 
(injections) the patient was compliant divided by the total number of administrations (injections) 
the patient was planned to take during the treatment epoch (ie, from the 1st to the last 
administration).

Treatment compliance percentages will be summarized descriptively as quantitative variables 
(Number, Mean, SD, Median, Min, and Max). The percentage of patients whose compliance is 
<80% will be summarized. In addition, patients with the wrong dose or an overdose will be 
summarized. 
Cases of overdose (administering 2 or more sarilumab doses in less than 11 calendar days) will be 
listed as such.  More generally, dosing irregularities are listed in Section 2.2.1. 
2.4.4 Analyses of safety data 
General common rules 
All safety analyses will be performed on the safety population as defined in Section 2.3.2, unless 
otherwise specified, using the following common rules: 
• 
The baseline value for safety parameters is the original baseline from the previous studies. 
• 
The value at Week 0 is the last non˜ missing measurement in data collected at scheduled 
visits: visit1, visit2 and/or visit1/2 in LTS11210 or EOT visit of previous studies prior to 
first IMP in LTS11210 study design. 
• 
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, vital signs and ECG (PCSA version in BTD-009536 version 3, see 
Appendix A). 
• 
PCSA criteria will determine which patients had at least one PCSA during the TEAE 
period, taking into account all evaluations performed during the TEAE period, including 
non-scheduled or repeated evaluations.  The number of all such patients will be the 
numerator for the on-treatment PCSA percentage.   
• 
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 received on the safety population. 
• 
For quantitative safety parameters based on central laboratory/reading measurements, 
descriptive statistics will be used to summarize results and change from baseline values by 
visit and treatment received.  Summaries will include the endpoint value. The endpoint 
value is commonly defined as the value collected at the same day/time of the last dose of 
investigational product. If this value is missing, this endpoint value will be the closest one 
prior to the last dose intake. 
• 
The analysis of the safety variables will be essentially descriptive and no systematic testing 
is planned.

2.4.4.1 Analyses of adverse events 
Generalities 
The primary focus of adverse event reporting will be on TEAEs. Pre-treatment and post-study 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, or TEAE. The algorithm for 
imputing date/time of onset will be conservative and will classify an AE as a treatment emergent 
unless there is definitive information to determine it is pre-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 by system-organ-class (SOC), High level group term 
(HLGT), High level term (HLT) and preferred term (PT) sorted in alphabetical order by treatment 
received and overall, 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 
dose group.  Overall counts will also be provided, counting each patient once and also counting 
the total number of events.  The denominator for computation of percentages is the safety 
population within the treatment group. 
The incidence and number of events per 100 patient-years (number of events adjusted for the total 
duration of exposure) will be provided for all the TEAE summaries.  In addition, the number of 
patients with event(s) per 100 patient-years (number of patients adjusted for the exposure up to the 
first event or up to the end of the duration of exposure for patients with no event) will also be 
provided for serious TEAEs and for each type of adverse event of special interest (AESI).  
Sorting within tables should ensure same presentation.  For that purpose, the table of all TEAEs 
presented by SOC and PT sorted by internationally agreed order of SOC and decreasing frequency 
of PT within SOC will define the presentation order for all other tables unless otherwise specified.  
Sorting will be based on results for overall sarilumab group. 
Listings will be provided for all pre-treatment AEs, all TEAEs, all SAEs, all CV events undergone 
adjudication, and TEAEs leading to treatment discontinuation with flags indicating on-treatment 
status 
Analysis of all TEAE(s) 
The following TEAE summaries will be generated for the safety population.

maximum) of all laboratory variables (central laboratory values and changes from baseline) will 
be calculated for each visit or study assessment (baseline, each post baseline time point, and 
endpoint) by treatment received.  This section will be organized by biological function as specified 
in Section 2.1.3.3. 
The incidence of PCSAs (list provided in Appendix C) at any time during the TEAE period will

There will be no confirmatory analysis for the efficacy variables. All analysis will be done 
descriptively on the safety population by visit in observed case, as appropriate.  In addition to the 
by-visit analysis, efficacy assessments summarized on a yearly basis will be provided. 
The baseline value for efficacy parameters is the original baseline from the previous studies. The 
value at Week 0 is the last non˜mi ssing measurement in data collected at scheduled visits: visit1, 
visit2, and/or visit1/2 in LTS11210 or EOT visit of previous studies prior to first IMP in 
LTS11210 study. 
For categorical variables, for example, percentage of patients who have maintained/reached 
ACR20 overtime, the number and percentage will be provided from all patients who have data 
available at that time point, and the 95% confidence intervals (CI) will be calculated if 
appropriate. 
For continuous variables, descriptive statistics such as the mean, standard deviation, median, 
minimum and maximum will be provided.  In addition, 95% confidence interval of the mean will 
be presented.  This applies to the original values and change (or percent change) from baseline.   
The 2-year (EFC11072 52 weeks + LTS11210 48 weeks) X-ray data  from Campaign 1 will be 
described using the van der Heijde modified total Sharp score for the subset of patients who 
previously completed study EFC11072, Part B when the 2-year X-ray data are available for all 
these patients. The modified total Sharp score and the change from baseline in the modified total 
sharp score will be described using mean, standard deviation, median, minimum and maximum, 
along with 95% confidence intervals. There is no formal treatment comparison and no alpha 
adjustment will be made (further analyses will be in the report of integrated summary of efficacy). 
In addition, the incidence of radiographic progression will be summarized using descriptive 
statistics.

summarized using arithmetic and geometric means, standard deviation (SD), standard error of the 
mean (SEM), coefficient of variation (CV%), minimum, median and maximum by actual dose and 
visit.  Concentrations below LLOQ were replaced by LLOQ/2.  
After the completion of EFC11072 (Mobility) Part B study, the Sponsor made the decision to 
discontinue measurement of bound sarilumab concentration from ongoing studies globally. Serum 
concentrations of bound sarilumab (serum sarilumab-sIL-6Rα complex) will not be summarized in 
this study.

DATA HANDLING CONVENTIONS 
2.5.1 General conventions 
The following formulas will be used for computations of parameters. 
Demographic formulas 
Age is calculated as follows: 
Age = (informed consent date – birth date)/365.25 
BMI is calculated as follows: 
BMI = Weight in kg/(height2 in meters) 
Renal function formulas 
Creatinine clearance (CLcr) value will be derived using the equation of Cockroft and Gault: 
CLcr (ml/min) = (140 - age) * weight (kg) * (1 - 0.15*sex (0-M, 1-F)) /(0.814*creatinine (µmol/l))

Page 56 
CLcr will be calculated using weight assessed at the same visit that creatinine was assessed and 
age at the lab sampling date. Age is calculated as follows: 
Age = (laboratory sampling date – birth date)/365.25 
Number of TEAE per 100 patient years 
The number of TEAE per 100 patient years is defined as the total number of TEAEs divided by 
the total exposure (expressed under the unit of 100 patient years) of the corresponding treatment 
group. Specifically, it is calculated as follows for each treatment group: 
Number of TEAE/100 patient years = (Total number of TEAEs) / total treatment duration (Unit: 
100 patient years) 
The total treatment duration is defined as [(end of TEAE period) – (date of first IMP) + 1], where 
the end of TEAE period is defined as minimum [(the last IMP + 60 days), (last contact date), 
(death date)], where the last contact date is defined as maximum [last complete AE start date, last 
visit date, last subject vital status date]. 
The number of PCSA per 100 patient years for the laboratory values, vital signs and ECGs will be 
defined similarly.  
Number of patients with special event per 100 patient-years 
The number of patients with at least one specific event per 100 patient-years will be calculated as 
the number of patients having a specific event in question divided by the total person-year among 
patients at risk of an initial occurrence of the specific event in question. In particular, it is 
computed as follows: 
∑
×
it
n
100
 
Where n is the number of patients with the specific events; ti is patient exposure time in 
person-year unit. For each of the specific events of interest, the exposure time for patients who 
have experienced the specific events will be defined as the time to first specific event in question, 
whereas the exposure time for those who have not had this specific event will be total duration of 
exposure as defined above. Please note, the time to first PCSA will be calculated using the 
midpoint of the time interval between the first assessment showing the PCSA and the previous 
assessment.

2.5.2 Data handling conventions for efficacy variables 
The missing data handling rules are summarized in a table in Appendix C. 
ACR20/ACR50/ACR70 
In the primary method of missing data handling, the data collected after treatment discontinuation 
will be set to missing. No imputation of missing post-baseline values will be performed. 
Responder status will be determined if possible. With these rules patients will automatically 
become non-responders for all time points beyond the time point they discontinue study treatment. 
Patients with insufficient data (ie, TJC, SJC, and at least 3 of the remaining 5 ACR components) 
at baseline and a time point will be non-responders in ACR20/ACR50/ACR70 at that time point. 
ACR components - TJC/SJC 
When calculating the TJC and SJC, with individual missing joint scores (the ‘”replaced or fused” 
joints are not taken into consideration for the swelling or tenderness) imputed as the mean of the 
scored joints, the TJC/SJC after imputation are as follows: 
TJC/SJC = sum (scored tender/swollen joints)*(number of joints in the full joint set / number of 
scored tender/swollen joints) 
The number of joints in the full joint set is defined as (68 – number of replaced or fused joints) for 
tenderness; (66 – number of replaced of fused joints) for swollenness; and the scored joints refer 
to those with an answer (0 – no pain, 1- pain). 
ACR components - HAQ-DI 
The highest score for any component question in a category determines the category score. If the 
patient is using assistance for any of these activities, scoring may be adjusted. The total score is 
the sum of all category scores divided by the number of answered categories. At least 6 categories 
should be answered in order to have a total score. 
DAS28-CRP 
When calculating DAS28-CRP, the following rules will be applied in order: 
• 
When calculating the 28TJC and 28SJC, with individual missing joint scores (the 
“replaced or fused” joints are not taken into consideration for the swelling or tenderness) 
imputed as the mean of the scored joints, the tender/swollen joint counts after imputation 
are as follows: 
28TJC/28SJC = sum (scored tender/swollen joints)*(number of joints in the full joint 
set / number of scored tender/swollen joints)

The number of joints in the full joint set is defined as (28 – number of replaced or fused joints) 
and the scored joints refer to those with an answer (0 – no pain, 1- pain). 
• 
No imputation will be performed. 
• 
If any of the 4 variables: 28TJC, 28SJC, GH (patient global), CRP is missing, then 
DAS28-CRP will be set to missing. 
SF-36 
The score of each of the 36 items is collected on the CRF.  Appendix I provides the SAS code to 
calculate the 8 scales, the 2 summary measure scores and standardized summary scores. 
The PCS and MCS summary measure scores will be computed if at least 50% of the component 
scales are available.  The scale scores will be computed if at least 50% of the items are available 
and valid within the corresponding scale.  The missing items will be imputed by the mean of 
available items. 
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 computation of treatment duration if investigational drug end of treatment date is 
missing 
For the calculation of the treatment duration, the date of the last dose of IMP is equal to the date of 
last administration reported on the dosing CRF page. If this date is missing, the exposure duration 
should be kept as missing.  
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, so it cannot be determined whether it was taken prior or 
concomitantly, it will be considered as a prior and concomitant medication. 
Handling of AEs with missing or partial date/time of onset 
Missing or partial missing AE onset dates and times will be imputed so that if the partial AE onset 
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. No imputation of AE end dates/times will 
be performed.  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 59 
Handling of AE when date and time of first investigational drug date is missing 
When the date and time of the first investigational drug is missing all adverse events that occurred 
after or on the day of enrolled should be considered as treatment-emergent adverse events. The 
exposure duration should be kept as missing. 
Handling of missing relationship to investigational product of AEs 
If the assessment of the relationship to investigational product is missing, then the relationship to 
investigational product has to be assumed and the AE considered as such in the frequency tables 
of possibly related AEs, but no imputation should be done at the data level. 
Handling of missing severity of AEs 
If the severity is missing for one of the treatment-emergent occurrences of an AE, the maximal 
severity on the remaining occurrences will be considered. If the severity is missing for all the 
occurrences a “missing” category will be added in summary table. 
Handling of PCSA  
If a patient has a missing baseline, that patient will be grouped in the category  “normal /missing at 
baseline”. 
For PCSA with two conditions, one based on a change from baseline value or a normal range and 
the other one on a threshold value, the first condition being missing, the PCSA will be based only 
on the second condition. 
For PCSA defined on a threshold and/or a normal range, this PCSA will be derived using this 
threshold if the normal range are missing; e.g., for eosinophils the PCSA is > 0.5 Giga/L or >ULN 
if ULN ≥ 0.5 Giga/L. When ULN is missing the value 0.5 should be used. 
Measurements flagged as invalid by the laboratory will not be summarized nor be taken into 
account in the computation of PCSA values. 
2.5.4 Windows for time points 
For efficacy parameters (except X-ray), a discontinuation visit (EOT, Visit 49) will be mapped to 
the scheduled visit for the analyses. If a discontinuation visit happens at a regular visit, then the 
visit number will be reassigned as the regular visit number where an assessment is planned. If a 
discontinuation visit happens between 2 regular visits, then the visit number will be reassigned to 
the next visit number where an assessment is planned. For example, if a discontinuation visit 
happens between Visits 9 and 10, then the visit number will be reassigned as 10. Similarly, the 
EOT visit (Visit 49) for patients who complete the study with 260-week treatment duration per 
Protocol Amendment 8, will be mapped to the Visit 28.

For X-ray data, the linear extrapolation method for the modified total Sharp score, the erosion 
score, and the joint space narrowing score will use true date to extrapolate missing values at 
Weeks 48, 96, 144, and 192 with no visit remapping. 
All efficacy analyses will be performed by the nominal visit number and no visit window will be 
defined. 
For safety assessments, the reference date for the derivation of relative days of events or findings 
will be the date of first drug intake as documented in the study drug administration page of the 
eCRF.  Selected safety variables will be summarized using the visit window defined in Table 6 for 
the by-visit descriptive analysis. Note that only the laboratory measurements performed at the 
central laboratory will be used for the by-visit descriptive analysis. All available values obtained 
between two visits including unscheduled measurements will be assigned to the appropriate visit 
window.  The following rule will be applied when mapping the measurements to the visit: 
1. When a patient has more than one measurement on the same laboratory parameter (or vital 
sign or ECG) on the same date, then the one with the later/largest sample ID will be used. 
2. For the same laboratory parameter (vital sign or ECG), if a patient has more than one 
measurement at different dates within the same visit window, the scheduled measurement 
that is closest to the target date will be used. If there is no scheduled measurement within 
the visit window, the unscheduled measurement that is closest to the target date will be 
used.  
3. When a patient has more than one measurement on the same laboratory parameter with the 
same distance from the target date, select the one with the latest date.

INTERIM ANALYSIS 
This is an open-label study. Interim reports may be prepared for regulatory submissions or other 
purposes. However, no alpha adjustment is needed for the final CSR. 
Interim reports for BLA submissions (FDA, EU MAA, etc) 
In general, the analyses for these reports will be performed in the overall sarilumab group, and not 
according to previous treatment prior to enrollment into LTS11210 due to ongoing imbalanced 
enrollment from previous studies, different previous treatment duration and rescue sarilumab in 
EFC11072, except the disposition tables and some special safety analyses such as neutropenia.  
Only selected efficacy and safety analyses will be determined and performed for the interim 
reports. PK and ADA analyses will be performed on certain cut-off data in each interim report 
since not all time points are reached by patients or by study design.  The analysis of patient 
reported outcomes may not be performed. However, the full analyses described in this SAP will be 
performed in the final CSR.

Missing tender/swollen joints: When calculating the TJC and SJC, with individual missing joint scores (the ‘replaced or fused’ joints are not taken into 
consideration for the swelling or tenderness) imputed as the mean of the scored joints, the TJC/SJC after imputation are as follows: 
TJC/SJC = sum (scored tender/swollen joints)*(number of joints in the full joint set / number of scored tender/swollen joints) 
The number of joints in the full joint set is defined as (68 – number of replaced or fused joints) for tenderness; (66 – number of replaced of fused joints) 
for swollenness; and the scored joints refer to those with an answer (0 – no pain, 1- pain). 
Missing questions/categories for HAQ-DI: The highest score for any component question in a category determines the category score. If the 
patient is using assistance for any of these activities, scoring may be adjusted. The total score is the sum of all categories’ scores divided by the 
number of answered categories. At least six categories should be answered in order to have a total score. 
Missing items within a measurement:   No imputation of missing post-baseline values will be performed. Responder status will be determined if 
possible.

  X-Ray missing data imputation process 
Details of the radiographic score derivation process conducted by BioClinica, Inc. are described in 
the supplementary document entitled “X-Ray Score Derivations Process for Determination of 
Adjudication in Rheumatoid Arthritis Clinical Trials”. 
Handling of missing joint data 
The handling of missing joint data and the logistics for being able to calculate mTSS change score 
are given below and outlined in the attached document: 
• 
The first step is to determine the adequacy of the joints in each segment. In case of missing 
or inadequate (eg. confirmed surgery, technical reasons) scores for a joint at one particular 
time point, it will first be determined whether these missing joint scores qualify for 
imputation. On a per joint basis, eligibility for imputation depends on the number of 
missing or inadequate joints in a segment in relation to the number of adequate joints in 
that segment. If the number of adequate joints is below the adequacy threshold, imputation 
of change scores will not be done (see below).

PIP: proximal interphalangeal, MCP: metatarsophalangeal. 
If, for example, 4 joints of the PIP segment (erosion) are missing or inadequate and 4 joints are 
adequate, that segment will be set to missing for that time point, implying that this segment cannot 
be imputed. 
Change from baseline (change score) will be calculated for each joint, in each of the 8 segments, 
at each time point. For adequate segments with individual missing joint scores (missing due to 
definite surgery/joint replacement or radiographically inadequate), the mean change from baseline 
for the adequately scored joints within the corresponding segment (ie., left and right sides

together) will be calculated, and that mean change score will be used to impute the missing change 
score for the joints with missing joint score. 
• 
The next step in the algorithm is to determine the adequacy of the time points per reader 
per patient. 
- 
Baseline time point: All 8 segments must be adequate at the baseline time point for the 
baseline time point to be considered adequate. 
- 
Follow-up time point: At least 5 segments must be adequate at a following-up time 
point for the time point to be considered adequate. Note that these 5 adequate segments 
can be composed of only hand segments if the foot segment is inadequate. 
For adequate follow-up time points that have less than 4 inadequate segments, the missing joint 
change score within inadequate segment will be calculated by using the mean of the total mean 
change from baseline of adequate segments to impute the change score of every joint with a 
missing value within the inadequate segments. 
• 
The third step is to determine the adequacy of the reads per patient. 
- 
If both readers consistently score X-rays of all time points as adequate or inadequate, 
then both reads are considered adequate.  
- 
If both readers score baseline as inadequate, then the patient will not proceed to 
adjudication even if a follow-up time point is scored by one reader as adequate and the 
other reader as inadequate. 
- 
If one reader scores a time point as inadequate while the second reader scores the same 
time point as adequate, then the reads are considered inadequate and the patient will 
proceed to adjudication (all time points). 
Adjudication 
A patient will be selected for adjudication based on the following criteria: 
• 
Technical adequacy: One reader scores inadequate segments within a time point while the 
second reader scores adequate segments within the same time point, then the patient will 
proceed to adjudication (all time points). 
• 
Total change score: The total change score for a time point is the sum of all individual 
joint change scores (erosion and JSN) from the 8 segments within the time point. If the 
difference between the two readers’ change scores is > ±10 at a follow-up time point, this 
patient will be adjudicated (all time points). 
At each time point, the mean (rounded to 1 decimal place) of the two primary readers’ total 
change score will be calculated, and that mean will be the total change score in mTSS for each 
corresponding time point. The mTSS will be back calculated as the total change score + baseline. 
In cases of adjudication, the following rules will be applied:

• 
In adjudication cases where the differences between the two primary readers’ change score 
is > ±10, the mean of the adjudicator and the primary reader with a closer total change 
score will be calculated, and that will be the total change score of the mTSS.  
• 
In adjudication cases of technical inadequacy in one primary reader, the mean of the other 
primary reader and the adjudicator will be calculated, and that will be the total change 
score of the mTSS.  
Handling of missing mTSS data:  
The imputation methods for missing radiographic data in randomized clinical trials in rheumatoid 
arthritis are compared in Huang et al.’s article “Missing radiographic data handling in randomized 
clinical trials in rheumatoid arthritis” as in the supplementary document which will appear in the

  SF-36 V2 Scoring 
General Scoring information 
Items and scales are scored in 3 steps 
• 
Step 1. Item recoding, for then 10 items that require recoding 
• 
Step 2. Computing scale scores by summing across items in the same scale (raw scale 
scores) 
• 
Step 3. Transforming raw scale scores to a 0-100 scale (transformed scale) 
Item recoding 
• 
All 36 items should be checked for out-of-range values prior to assigning the final item 
value. All out-of-range values should be recoded as missing data. 
• 
The following tables show the recoding of response choice 
How to treat missing data 
A scale score is calculated if a respondent answered at least half of the items in a multi-item scale 
(or half plus one in the case of scales with an odd number of items). 
The recommended algorithm substitutes a person-specific estimate for any missing item when the 
respondent answered at least 50 percent of the items in a scale. A psychometrically sound estimate 
is the average score, across completed items in the same scale, for that respondent. For example, if 
a respondent leaves one item in the 5-item mental Health scale blank, substitute the respondent’s 
average score (across the 4 completed mental health items) for that one item. When estimating the 
respondent’s average score, use the respondent’s final item values. 
Computing raw scale scores 
After item recoding, including handling of missing data, a raw score is computed for each scale. 
This score is a simple algebraic sum of responses for all items in that scale. 
If the respondent answered at least 50%of the items in a multi-items scale, the score can be 
calculated. If the respondent did not answer at least 50% of the items, the score for that scale 
should be set to missing. 
Transformation of the scale scores 
The next step involves transforming each raw score to a 0 to 100 scale using the following 
formula:

Transformed scale = [(actual raw score – lowest possible raw score) / possible raw score range] x 
100 
This transformation converts the lowest and highest possible scores to zero and 100, respectively.

Appendix K 
  Analysis Plan of the PFS-S Study 
This appendix is the statistical analysis plan for the PFS-S sub-study.   
Pre-filled syringe with safety system (PFS-S) 
Sarilumab has been delivered via prefilled syringes (PFS) in most of the Phase 3 studies.  
The pre-filled syringe with safety system (PFS-S) is a modified version of the prefilled syringe 
aimed at preventing needle stick injury by either the patient or by a caregiver (professional or 
non-professional) performing the administration. The “safety system” consists of a sharps injury 
prevention feature, which can be described as a sheath that automatically covers the needle once 
the injection is completed and thus prevents needle stick injury and re-use.  
Compared to PFS, PFS-S also includes: 
• 
a rigid needle shield that encloses the soft rubber needle shield covering the needle  
• 
a finger flange with an ergonomic design and a large piston rod 
The following figures show the unused and used PFS-S. At the end of the injection when the 
plunger rod has been pushed into the syringe as far as it will go, the needle safety shield is 
activated which can be seen as the syringe is pulled away from the skin.

Study design 
This is a Phase 3, multicenter, worldwide, non-randomized, open-label, 1-arm, 12-week sub-study 
of the LTS11210/SARIL-RA-EXTEND study. The sub-study will only be performed in limited 
sites in selected countries.  
Patients at participating sites who have been enrolled in the main study (LTS11210) for at least 24 
weeks and are willing to participate in the sub-study will be enrolled in the sub-study. The entry 
into the sub-study (V101) will be at any scheduled visit in the main study from Visit 8 (Week 24) 
or after. Sarilumab 150 mg q2w PFS-S or sarilumab 200 mg q2w PFS-S will be used in the 
sub-study to replace the sarilumab 150 mg q2w PFS or 200 mg q2w PFS used in the main study. 
At the entry into the sub-study (V101), the patients/persons performing injections will be trained 
how to use the PFS-S, and the sub-study injection diary will be dispensed to replace the patient 
diary of the main study. All the procedures described in the sub-study are additional to the main 
study activities, unless specified to replace procedures in the main study. 
The patient/person performing each sub-study injection will respond to 3 questions related to 
PFS-S use on the injection diary after each PFS-S injection. A “no” response to any of these 3 
questions will be defined as a product technical complaint (PTC). For any PTC, the Investigator 
will complete a PTC form and will send this PTC form together with the PFS-S that triggered this 
PTC back to the Sponsor according to a predefined process. The patients should be instructed to 
keep any PFS-S associated with a PTC separately from other PFS-S, so it can be identified when 
returned to site at the end of sub-study. The sponsor will validate or invalidate the occurrence of a 
product technical failure (PTF), which is defined as a PTC that has a validated technical cause. 
For patients receiving sarilumab 200 mg q2w PFS-S the dose can be reduced to 150 mg q2w 
PFS-S at any time during the sub-study duration if the defined criteria specified in the main 
protocol for dose reduction are fulfilled.  
When the patients have completed the 12 weeks of the sub-study they will return to the clinic to 
complete Visit 102 (V102) in addition to the scheduled main study visit on that day. They will 
switch back to the main study and continue sarilumab treatment through PFS.  
If the patient chooses to end the participation in the sub-study during the sub-study duration but to 
continue in the main study with IMP administration via PFS, the V102 should still be completed 
and the patient should switch back to take IMP administration through PFS on and after V102 per 
the patient’s IMP administration schedule. 
If a patient discontinues Investigational Medicinal Product (IMP) permanently in LTS11210 
during the sub-study, he/she should complete all procedures planned for V102 in the sub-study as 
well as the end of treatment (EOT) and post treatment follow-up visits in the main study (see 
flowchart in main study).

Study objective 
Primary 
To assess the usability of the sarilumab pre-filled syringe with safety system (PFS-S) when 
administered to patients with active Rheumatoid Arthritis (RA) 
Secondary 
To document the safety of sarilumab 200 mg q2w PFS-S and sarilumab 150 mg q2w PFS-S. 
 
Determination of sample size 
The sample size of this sub-study is based on empirical consideration. No formal sample size 
calculation is performed but an estimate of 120 patients included in this sub-study with up to 
6 injections per patient will provide approximately 680 injections to evaluate PTF during the 
12 weeks of the study assuming 5% drop-out rate.

All assessments planned to be performed at the scheduled main study visit that coincides with the 
sub-study visit, are described in the main study flow charts. Below flowchart specifies only:  
• 
those actions that are additional to the scheduled main study visit in LTS11210 
• 
those actions that replace an action in the scheduled main study visit in LTS11210 (for 
example, study drug dispensing  of the PFS-S IMP format, instead of the main study IMP 
in PFS)

Each patient will participate in the sub-study for a period of 12 weeks from the first sub-study visit 
(V101) to the final sub-study visit (V102). At the time of V101, eligible patients will start 
receiving sarilumab 200 mg q2w PFS-S or sarilumab 150 mg q2w PFS-S, if they reduced the dose 
in the main study per protocol, for 12 weeks as replacement of original sarilumab PFS in the main 
study in addition to background disease modifying anti-rheumatic drugs (DMARDs) therapy, if 
any. There is no post-treatment follow-up specific to the PFS-S sub-study, as all patients except 
patients who discontinue IMP permanently in LTS11210 during the sub-study will switch back to 
the main study at V102. For patients who discontinues IMP permanently in LTS11210 during the 
sub-study, they should complete all procedures planned for V102 in the sub-study as well as the 
end of treatment (EOT) and post treatment follow-up visits in the main study The last 
on-treatment sub-study visit for patients who complete the sub-study will occur at Day 85 (Visit 
102). The sub-study will be considered completed when the last sub-study patient has completed 
V102. 
Statistical analysis procedures and method 
The phrase ‘treatment group’ used throughout this appendix refers to the following device/dose 
groups (PFS-S sarilumab 200 mg q2w, PFS-S sarilumab 150 mg q2w, PFS-S sarilumab 200 mg

q2w to 150 mg q2w ).  The baseline value is defined as the original baseline in initial/previous 
studies before LTS11210, as in the main study. 
 
Disposition of patients 
Below describes patient disposition for both patient study status and the patient analysis 
populations for the sub-study only, unless otherwise specified. 
• 
All screened patients are defined as those patients who signed the informed consent for the 
sub-study.

eligibility criteria to enter into the sub-study.   
• 
The Safety population consists of all enrolled patients who received at least one dose of the 
IMP administered via PFS-S during this sub-study. 
• 
The PK population consists of all enrolled patients on stable dose of sarilumab (receiving 
the same dose of sarilumab without treatment interruption) at least 24 weeks prior to V101 
until V102 who receive at least 1 dose of the IMP and at least one non-missing serum 
concentration value during this sub-study. 
For patient study status, the total number of patients for each one of the following categories will 
be presented using a summary table:

Demographics and baseline characteristics  
Demographics and baseline characteristics will be presented for the enrolled patients in this 
sub-study. 
Extent of investigational product exposure and compliance 
The extent of study treatment exposure and compliance will be assessed and summarized by actual 
treatment received within the safety population. 
The duration of IMP exposure is defined as: last dose date – first dose date at D1 + 14 days 
(regardless of unplanned intermittent discontinuations).   
Treatment compliance to the IMP is defined as the actual number of doses received compared to 
the scheduled number of doses during the treatment period.  Treatment compliance during the 
treatment period in the sub-study will be summarized descriptively. 
Efficacy (Device) analysis 
Data will be described for the 12 weeks of this sub-study using the safety population. The efficacy 
analyses will be performed using descriptive statistics and presented by treatment group. 
 
Primary endpoint 
The primary endpoint is the number of validated PFS-S-associated PTFs.  
The injection diary will include specific questions about PTCs. The person performing each 
sub-study injection will record the answers to these questions in the diary each time he/she 
performs an injection with a PFS-S. 
The questions include: 
1. Were you able to remove the cap? 
• Yes 
• No 
 
  If no, please describe / explain:  
2. Was the needle safety system activated?  
• 
Yes 
• 
No 
                If no, please describe / explain:  
3. Did the safety system entirely cover the needle? 
• 
Yes

At Week 12 (Visit 102), the Investigator will review the diary, confirm with the patient whether 
there are any problems associated with the use of PFS-S and record the responses in the e-CRF.   
If the answer is “no” to any of the questions stated in the diary, the patients will be asked to 
provide further details of the complaint and a PTC form will be completed by the investigator. The 
PTC form and the PFS-S associated with PTC will be sent to the Sponsor following the 
pre-defined process. The sponsor will validate or invalidate the occurrence of a PTF. If the PTF is 
ruled out, the event is considered as a failed drug delivery (FDD) that is defined as patient’s 
failure to administer the full dose at a given attempt. 
In addition, another question will be asked in the diary to confirm whether the person who 
performed the injection was trained:

Number and percentage of patients with FDDs 
Safety analysis  
Adverse events related to PTC per investigator’s judgment will be summarized by treatment group 
during the sub-study. If an adverse event reported during the sub-study is considered linked to a 
PTC by the investigator the potential link with the PTC should be specified in AE/SAE verbatim. 
If a laboratory or ECG abnormality or vital signs finding reported during the sub-study is 
considered clinically significant and linked to a PTC by the investigator an adverse event needs to 
be reported and the potential link with the PTC should be specified in AE/SAE verbatim.  
Injection site reaction adverse events will be summarized during the sub-study period (that is, 
those events with start date from the date of first dose of the sub-study to the date of last sub-study 
dose+14 days, but no later than one day before the date of next non-sub study dose). The specific 
summaries to be performed are described for the main study. 
Other adverse events, such as needle stick, skin irritation, etc, occurring during the sub-study 
period will be reviewed manually to evaluate if the events are related to the device. For the events 
related to the device but not PTC, a summary table will be provided or event description will be 
provided in details if only a few events reported.

Note:  The safety analyses for the sub-study will be limited to the AEs noted above.  Overall AEs, 
laboratory values, vital signs, and electrocardiograms (ECG) that occurs for patients participating 
in the sub-study will be described with the main LTS11210 study results.    
 PK analysis 
Serum concentrations of functional sarilumab will be summarized using standard descriptive 
statistics by visit.  
For PK parameters Ctrough, estimates and 90% CIs for the ratio of geometric means (Day 85 versus 
Day 1) will be provided using a linear fixed effects model on the log-transformed data. Serum 
trough concentrations of functional sarilumab will be evaluated in patients on stable dose of 
sarilumab at V101 (D1) before using the PFS-S. Patients are considered to be on stable dose of 
sarilumab at V101 (D1) if they receive the same dose of sarilumab without treatment interruption 
for at least 24 weeks in LTS11210 prior to V101. Patients changing dose during the 12 week 
sub-study will be excluded from the Ctrough analyses 
Interim analysis 
No interim analysis is planned for this sub-study.
