SUBSTANTIAL GLOBAL AMENDMENT 6 
Amendment rationale 
This amendment rationale applies to global protocol AC-058B301 Version 6, dated 
30 August 2017. The resulting amended global protocol is Version 7, dated 5 December 
2018. 
The main reason for this amendment is to revise the secondary endpoints multiple testing 
strategy as explained further below. This revision is not based on information collected in 
the OPTIMUM study and no analysis has been performed on the OPTIMUM data to 
develop this proposal. All data collected remain fully blinded to the sponsor: 
i. 
Reduce the number of secondary endpoints in the OPTIMUM study from five to 
four to reduce the complexity of the testing strategy by including only the 
following: 
o Change from baseline to Week 108 in fatigue-related symptoms as 
measured by the symptoms domain of the Fatigue Symptom and Impact 
Questionnaire-Relapsing Multiple Sclerosis (FSIQ–RMS) 
o Cumulative number of Combined Unique Active lesions (CUAL) from 
baseline to Week 108 
o Time to 12-week Confirmed disability accumulation (CDA) from baseline 
to End of Study (EOS) 
o Time to 24-week CDA from baseline to EOS 
The “Time to 24-week CDA from baseline to EOS” endpoint will be moved from 
the exploratory endpoints to the category of secondary endpoints and the endpoints 
“Time to first confirmed relapse” and “Percent change in brain volume (PCBV) 
from baseline to Week 108” will be moved from the secondary endpoints list to the 
category of exploratory endpoints. 
The “Guideline on clinical investigation of medicinal products for the treatment of 
Multiple Sclerosis” [EMA 2015], dated 26 March 2015, recommends confirmation 
of disability accumulation based on a confirmatory Expanded Disability Status 
Scale (EDSS) at least 6 months apart as a relevant endpoint. From a regulatory point 
of view and as per EMA feedback to the sponsor, the “Time to 24-week CDA from 
baseline to EOS” endpoint would be relevant to be included as a secondary 
endpoint.  
The endpoints “Time to first confirmed relapse” and “PCBV from baseline to Week 
108” do not add substantial information on clinically important effects of the study 
drug on MS disease for the following reasons:

o The endpoint “Time to first confirmed relapse“ is highly correlated to the 
primary endpoint of ARR. Thus, although this endpoint may provide some 
additional insight into the drug’s effect on relapse activity, it is not expected 
to add relevant information to what is already available through the primary 
endpoint of ARR.  
o The clinical significance of brain volume loss in MS and the relevance of 
the endpoint “PCBV from baseline to Week 108” remains unclear as the 
degree of change in whole brain volume measurement that results in a 
clinically meaningful benefit is not well defined due to several 
methodological limitations in brain volume measurements. 
 
ii. 
Modify the multiple testing strategy for the control of the type I error by testing the 
secondary endpoints according to a fallback type method. As compared to the 
previously planned fixed-sequence hierarchical method, this will provide some 
opportunity to test an endpoint later in the sequence even if an endpoint tested 
earlier in the sequence has failed to show statistical significance. If statistical 
superiority of an endpoint tested earlier in the sequence can be shown the 
corresponding alpha can be passed on to endpoints later in the sequence. As a 
consequence, endpoints tested late in a fallback sequence are given a higher weight 
as compared to endpoints at the beginning of the sequence. This is in contrast to the 
previous planned hierarchical fixed sequence approach where endpoints at the 
beginning of the sequence receive a higher weight. To maintain the same weight 
ranking of the secondary endpoints it is proposed to change the order in the 
sequence. 
The hypothesis for the primary endpoint of ARR is first tested with the full alpha. 
If the primary endpoint null hypothesis is rejected, the alpha will be split evenly 
(1/3 of alpha) between the following three secondary endpoints using the fallback 
procedure, allowing for passing on alpha as per the following sequence: 
o Change from baseline to Week 108 in fatigue-related symptoms as 
measured by the symptoms domain of the FSIQ–RMS [Fatigue] 
o Cumulative number of CUAL from baseline to Week 108 [CUALs] 
o Time to 12-week CDA from baseline to EOS [12-week CDA]  
 
If a secondary endpoint listed as part of the fallback procedure above is successful, 
the preserved alpha is passed along to the next secondary endpoint in the sequence 
and the summed alpha is used for testing that endpoint. Thus, as sequential tests are 
successful, the alpha accumulates for the endpoints later in the sequence; these 
endpoints are then potentially tested with a progressively larger alpha, but always 
with at least 1/3 of the alpha.

In a last step, the secondary endpoint  
o Time to 24-week CDA from baseline to EOS [24-week CDA] 
 
is tested in a subsequent stage following Time to 12-week CDA with the remaining 
alpha.  
A graphical description of this testing strategy for the primary and secondary 
endpoints following the approach from Bretz, et al. [Bretz 2009] is provided in 
Figure 8 Overall testing strategy. 
Figure 8 
Overall testing strategy 
 
Based on the latest published information from recent MS trials, the disability 
accumulation rate is expected to be lower than assumed in earlier protocol versions 
[Cohen 2018, Comi 2018]. This results in a lower than anticipated probability of 
the study providing a robust evaluation of the effect of ponesimod on disability 
accumulation and, consequently, would have limited the ability to assess the other 
secondary endpoints with the previously planned hierarchical multiple testing 
strategy. The sponsor considers that the introduced fallback type multiple testing 
strategy optimizes the ability of the trial to obtain conclusive results on key disease 
parameters.  
Analyses for secondary endpoints will be conducted at an overall two-sided 5% 
alpha level, with multiplicity adjustment as per the above testing strategy. 95% 
confidence intervals will be presented. The statistical analyses sections and sample 
size calculations for the secondary endpoints have been updated accordingly.

Additional minor changes and clarifications were made to the protocol as follows: 
• Cladribine was added to the list of orally administered disease-modifying therapies. 
• It was clarified that oral taper of corticosteroids should not be administered in order 
to harmonize the treatment of relapses in the study and to minimize the risk of 
combined immunosuppression.  
• It was clarified that No evidence of disease activity (NEDA) status will be 
considered up to EOS. 
• It was corrected that health care utilization will be not be displayed by visit.  
• The possibility of using a chiral assay for the analysis of selected plasma PK 
samples was added to the protocol. Rationale: Metabolism of ponesimod may 
hypothetically result in chiral inversion of the parent compound to its S-enantiomer 
(ACT-128818). In plasma samples from rat and dog it was confirmed that this 
inversion did not occur in measurable quantities, using a chiral bioanalytical assay 
[ponesimod IB] but chiral inversion was never tested in humans. The validated 
bioanalytical assay that is currently being used in the study for the quantification of 
ponesimod is a non-chiral assay, not able to separate the enantiomers. 
• Wording was added to allow the analysis of biomarkers in the serum sample taken 
at Visit 2 (Baseline). 
• The definition of confirmed relapses was clarified. 
• It was clarified that the relapse assessment questionnaire may be completed during 
the additional safety blood draws (if applicable). 
• It was clarified that specific assessments collected at the end of treatment visit may 
be conducted up to 7 days prior to the last intake of study drug. 
• The definition of which EDSS assessment can qualify as confirmatory for 12- and 
24-week CDA was clarified in order to maximally use data provided by the 
investigator and minimize the impact of short-term relapse-related disability. 
Furthermore, some inconsistencies between sections in the protocol were corrected or 
clarified as follows: 
• The threshold for HHH grading for lymphocytes in Appendix 6 was aligned to the 
specifications in Sections 7.3.14.1 and 5.1.5.2. 
• The criteria leading to exclusion from the per-protocol set were aligned with the 
overall definition of the per protocol set regarding deviations that impact the

assessment of the primary or secondary endpoint leading to exclusion: Subjects 
developing discontinuation criteria that were not discontinued are not removed 
from per protocol analysis as these deviations are not considered to impact the 
assessment of the primary or secondary endpoint.  
In the statistical analysis section the following minor updates were made: 
• It was clarified that separate SAPs and reports will be prepared for the final analyses 
of PK data, the MRI sub-study and the Patient Preference sub-study.  
• Definition of highly active relapsing multiple sclerosis has been aligned with the 
updated therapeutic indications of Gilenya® in EMA [Gilenya® SmPC].  
• Treatment-emergent QTc > 450 ms, > 480 ms, > 500 ms are reported irrespective 
of gender to align with standard reporting. 
• For PFT reporting the provided thresholds are clarified to include subjects with a 
decrease of = 200 mL or = 12% in FEV1 or FVC.  
• The number of supportive / sensitivity statistical analyses was reduced to focus on 
the analyses required for the regulatory submission. 
• For the secondary endpoint change from baseline in FSIQ-RMS symptoms score to 
Week 108 reference to last observation carried forward has been removed and a 
repeated measurements ANCOVA using data from all scheduled visits (instead of 
an ANCOVA using only change from baseline to Week 108 data) will be applied 
to make use of all data collected at scheduled visits and make use of them in the 
analysis. 
• For the secondary and exploratory efficacy endpoints statistical models have been 
updated to adjust for the baseline result (where available) instead of the number of 
relapses in the year prior to study entry to increase statistical rigor and align with 
health authority recommendations. 
• For analyses of safety variables 95% CLs (not 99% CLs) are provided as they are 
considered descriptive analyses. 
• For analyses of AEs of special interest, and MACE, reference to logistic regression 
has been removed to align with analysis of specific safety events described in the 
introduction of Section 11.3.5.  
Finally, edits were done to correct typographical errors.

PROTOCOL SYNOPSIS AC-058B301 
TITLE 
Multicenter, 
randomized, 
double-blind, 
parallel-group, 
active-controlled, superiority study to compare the efficacy and 
safety of ponesimod to teriflunomide in subjects with relapsing 
multiple sclerosis (RMS) 
ACRONYM 
OPTIMUM: Oral Ponesimod vs Teriflunomide In relapsing 
MUltiple sclerosis  
OBJECTIVES 
Primary objective 
To determine whether ponesimod is more efficacious than 
teriflunomide in terms of reducing relapses in subjects with 
RMS. 
Secondary objectives 
1. To assess the effect of ponesimod on disability 
accumulation and on other aspects of multiple sclerosis 
(MS) disease control  
2. To assess the safety and tolerability of ponesimod in 
subjects with RMS. 
DESIGN 
Prospective, 
multicenter, 
randomized, 
double-blind, 
parallel-group, active-controlled, Phase 3, superiority study. 
PERIODS 
Pre-randomization period 
Up to 45 days before randomization. 
Treatment period 
The double-blind treatment period will last for 108 weeks. 
It will consist of a randomization visit, visits at two, four, and 
12 weeks after randomization, and 12-weekly visits thereafter.  
End-of-Treatment (EOT) 
• 
The EOT visit will take place at Week 108 (or earlier in 
case of premature discontinuation of study drug). In all 
cases, the EOT visit should take place one day after the last 
dose of study drug but no later than 7 days after the last 
dose of study drug.  
• 
Subjects who have completed treatment until Week 108 
will be proposed to enroll in an extension study conducted 
under a separate protocol. Subjects who discontinue study 
drug prematurely for any reason will not be eligible for the 
extension study.

• 
Subjects who prematurely discontinue study drug treatment 
should be subsequently treated according to local standard 
of care at the investigator’s discretion and will be followed 
in the post-treatment observation period. 
Post-treatment safety follow-up (FU) period:  
Teriflunomide is eliminated slowly from plasma. An 
accelerated elimination procedure must be used by all subjects 
after the last dose of study drug [see Section 5.1.14]. A safety 
FU after the last dose of study drug is mandated.  
All subjects will enter the safety FU period: 
• 
For subjects who enter the extension study, the FU period 
starts after the last dose of study drug and ends with a safety 
FU visit (FU1) 14–22 days after the last dose of study drug 
or with an abbreviated FU2 23–37 days after the last dose 
of study drug (if compliance to the teriflunomide 
accelerated elimination procedure was assessed as not 
sufficient at FU1).  
• 
For subjects who do not enter the extension study, the 
safety FU period lasts for 30 days after the last dose of 
study drug and includes two safety FU visits (FU1, FU2) at 
14–22 and 30–37 days after the last dose of study drug, 
respectively. 
Post-treatment observation period (PTOP): 
Subjects who prematurely discontinue study treatment will 
enter the PTOP which lasts until 108 weeks after randomization 
(i.e., planned EOT period). It consists of an abbreviated 
schedule of assessments at the time of the originally scheduled 
12-weekly visits.  
End-of-Study (EOS) 
• 
EOS is reached when treatment, safety FU, and, if 
applicable, PTOP have been completed. 
• 
For subjects who completed the 108-week treatment period 
and enter the extension study, the EOS visit corresponds to 
the FU visit (FU1) conducted 14–22 days after the last 
study drug dose or to the abbreviated FU2 visit conducted 
23–37 days after the last study drug dose (if needed for 
compliance reasons with the teriflunomide accelerated 
elimination procedure).

• For all other subjects, the EOS visit corresponds to the 
30-day FU visit (FU2) or to the last visit of PTOP (i.e., 
Week 108 Visit of the PTOP), whichever is last.  
PLANNED DURATION 
Approximately 171 weeks (3.3 years) from first subject first 
visit to last subject last visit. 
For an individual subject, the maximum duration of the study 
will be approximately 118 weeks (2.2 years). 
SITE(S) 
/ COUNTRY(IES) 
Approximately 200 sites in 25 countries in North America, 
South America, Eastern and Western Europe, Pacific (planned). 
SUBJECTS / GROUPS 
Approximately 1100 subjects will be randomized in 2 groups in 
a 1:1 ratio to receive ponesimod 20 mg (approximately 
550 subjects) 
or 
teriflunomide 
14 
mg 
(approximately 
550 subjects). 
Randomization will be stratified by prior use of MS 
disease-modifying treatment in the last two years prior to 
randomization (yes, no) and by baseline Expanded Disability 
Status Scale (EDSS) score (EDSS ≤ 3.5, EDSS > 3.5). 
INCLUSION CRITERIA 
This study will enroll adult male and female subjects aged 18 to 
55 years with established diagnosis of MS, as defined by the 
2010 revision of McDonald Diagnostic Criteria [Polman 2011], 
with relapsing course from onset (i.e., relapsing-remitting 
multiple sclerosis and secondary progressive multiple sclerosis 
[SPMS] with superimposed relapses). The trial will include up 
to a maximum 15% of subjects with SPMS with superimposed 
relapses.  
Subjects must have active disease evidenced by one or more MS 
attacks with onset within the period of 12 to 1 months prior to 
baseline EDSS assessment, or by two or more MS attacks with 
onset within the 24 to 1 months prior to baseline EDSS 
assessment, or with one or more gadolinium-enhancing (Gd+) 
lesion(s) of the brain on an MRI performed within 6 months 
prior to baseline EDSS assessment. Enrolled subjects must be 
ambulatory with an EDSS score of up to 5.5 inclusive. The 
subjects may be treatment-naïve (i.e., no MS disease-modifying 
therapy received at any time in the past) or previously treated

CONCOMITANT 
THERAPY 
Treatment of relapses 
• 
If a relapse requires treatment with corticosteroids, 
methylprednisolone 1 g intravenous (i.v.) daily for 3 to 
5 days is recommended (without an oral taper). Treatment 
with other corticosteroids or another dose, or other routes 
of administration, or adrenocorticotropic hormone (ACTH) 
is not recommended, unless deemed absolutely necessary 
by the investigator who will document the rationale. 
• 
Treatment 
of 
relapses 
with 
plasma 
exchange 
(i.e., plasmapheresis, cytapheresis) is prohibited. 
Allowed concomitant therapy 
• 
Dalfampridine (synonymous with fampridine) on a stable 
dose for at least 90 days prior to randomization and during 
double-blind treatment. Dalfampridine therapy must not be 
started or increased in dose during the study. Stopping or 
decreasing the dose of dalfampridine during the study 
should only take place if deemed absolutely necessary by 
the investigator. 
• 
Administration of i.v. atropine in the event of symptomatic 
bradycardia. 
• 
Short-acting ß2-agonists for respiratory symptoms and/or 
reduced pulmonary function during study drug treatment. 
• 
QT-prolonging drugs with known risk of Torsades de 
Pointes should be used with caution since ponesimod may 
potentially enhance their effect on QT interval. 
• 
Vaccination with non-live vaccines. Subjects receiving 
non-live vaccination while on study treatment will have 
5 mL of blood drawn prior to and ≥ 3 weeks after 
vaccination in order to assess changes in vaccine-specific

antibody titers from pre- to post-vaccination. Samples will 
be analyzed at the end of the study. 
• 
The following medication should be administered with 
caution and carefully monitored due to potential 
interactions with teriflunomide: medications metabolized 
by cytochrome P450 (CYP)2C8 and CYP1A2, potent CYP 
and transporters inducers, medications with a low 
therapeutic index such as warfarin, substrates of organic 
anion transporter 3 (OAT3), breast cancer resistant protein 
(BCRP) and the organic anion transporter polypeptide 
(OATP) family (especially 3-hydroxy-3-methylglutaryl 
coenzyme A reductase inhibitors).  
• 
Other treatments considered necessary for the subject’s 
wellbeing and not categorized as prohibited concomitant 
medications. 
Prohibited concomitant therapy  
• 
Systemic corticosteroids and ACTH, except for the 
treatment of MS relapses and for short-term treatment with 
low dose or inhaled corticosteroids for pulmonary 
conditions; 
• 
Disease-modifying drugs for MS other than prescribed as 
per protocol; 
• 
Immunosuppressive treatment; 
• 
i.v. immunoglobulin; 
• 
Plasmapheresis, cytapheresis, or total lymphoid irradiation; 
• 
Vaccination with live vaccines; 
• 
β-blockers, diltiazem, verapamil, digoxin, or any other 
anti-arrhythmic or heart rate (HR)-lowering systemic 
therapy; 
• 
Cholestyramine or activated charcoal unless needed for an 
accelerated elimination procedure [see Section 5.1.14]; 
• 
Any other investigational drug;  
• 
Any investigational therapeutic procedure for MS 
(e.g., stent 
placement 
or 
angioplasty 
for 
chronic 
cerebrospinal 
venous 
insufficiency, 
stem 
cell 
transplantation).

STATISTICAL 
METHODOLOGY 
The Full Analysis Set (FAS) includes all randomized subjects. 
In order to adhere to the intention-to-treat principle as much as 
possible, subjects will be evaluated according to the treatment 
they have been randomized to.  
The Per-Protocol Set (PPS) comprises data from all subjects 
included in the FAS without major protocol deviations as 
categorized in Section 11.1.3.

EudraCT 2012-000540-10 
Doc No D-18.388 
 
The Safety Set (SAF) includes all randomized subjects who 
received at least one dose of study treatment. Subjects will be 
analyzed based on actual treatment taken, not randomized 
treatment. 
Statistical model and hypotheses for primary efficacy 
endpoint 
A generalized linear model with negative binomial distribution 
will be fitted for the primary efficacy endpoint ARR. Two-sided 
hypotheses are expressed in terms of the model parameters 
µP20mg and µT14mg. The primary null hypothesis is that the ARR 
(µ) does not differ between ponesimod 20 mg and teriflunomide 
14 mg. The alternative hypothesis is that the ARR differs 
between ponesimod 20 mg and teriflunomide 14 mg. 
H0, ARR: µP20mg - µT14mg = 0 
vs 
H1, ARR: µP20mg - µT14mg ≠ 0 
The null hypothesis will be tested by a two-sided Wald test 
within the negative binomial regression model with a two-sided 
significance level of 0.01 for conclusive evidence and 0.05 for 
a positive study. Two-sided 99% and 95% Wald confidence 
intervals will be calculated for the relative reduction in mean 
ARR for ponesimod 20 mg compared to teriflunomide 14 mg. 
The primary statistical analysis of the ARR endpoint will be 
performed on the FAS using a negative binomial model for 
confirmed relapses, with the stratification variables prior use of 
disease-modifying therapies (DMTs) and EDSS category as 
well as the number of relapses in the year prior to study entry, 
included in the model and time in the study as an offset variable. 
Sensitivity analyses will be performed on the PPS and also 
based on different subgroups derived from baseline variables. 
The secondary efficacy endpoints will be tested if the primary 
analysis on ARR has led to the rejection of the null hypothesis 
in favor of ponesimod 20 mg at an overall two-sided 
significance level of 0.05. A fallback method will be used for 
testing the family of hypotheses related to the following three 
secondary endpoints:

• Absolute change of FSIQ-RMS from baseline to Week 108. 
• Cumulative number of CUAL from baseline to Week 108; 
• Time to 12-week CDA from baseline up to EOS; 
This is followed in a hierarchical manner by testing  
• Time to 24-week CDA from baseline up to EOS; 
at the remaining alpha.  
The endpoints will be analyzed using the FAS population. All 
secondary endpoints will also be analyzed using the PPS 
population. 
The sample size was calculated based on the primary endpoint, 
and power calculations are provided for the secondary 
endpoints. 
Sample size for the primary endpoint 
The sample size for the study was determined by a simulation 
using the negative binomial distribution. A sample size of 
1100 subjects (550 per treatment group) would provide a power 
of approximately 90% for a significance level of 0.01, under the 
assumption that ARR is 0.320 for teriflunomide 14 mg 
and 0.215 for ponesimod 20 mg (which corresponds to a risk 
reduction of 33%) and using a dispersion = 0.9. An annual 
dropout rate of approximately 15% for the first year and 
7.5% for the second year has been assumed. 
The adjusted risk reduction for teriflunomide 14 mg in the fixed 
2-year duration TEMSO study was 31.5%, and in the variable 
duration TOWER study it was 36%. An integrated analysis 
showed a pooled 34% reduction compared to placebo. A 33% 
reduction for ponesimod 20 mg compared to teriflunomide 
14 mg gives a relative 55% reduction compared to placebo, 
which is similar to that observed in the fingolimod Phase 3 
trials. The dispersion from the ponesimod Phase 2 study was 
1.0, the calculated dispersion from the TEMSO study is 0.8; the 
chosen dispersion is the mean of the two. 
Exploratory efficacy endpoints 
No multiplicity adjustments will be made on exploratory 
efficacy endpoints. Any two-sided p-value < 0.05 will be

identified as statistically significant but will only be considered 
as an exploratory result. 
Safety endpoints 
Safety endpoints will mainly be analyzed descriptively by 
treatment group on the SAF. 
STUDY COMMITTEES 
An Independent Data Monitoring Committee (IDMC) 
composed of physicians with relevant medical expertise 
(including a neurologist, a neurovirologist, a neurologist with 
MRI expertise or a neuroradiologist, a cardiologist, a 
pulmonologist) and a statistician will review unblinded subject 
safety and efficacy data on an ongoing basis and is empowered 
to recommend modifications to the protocol (to enhance subject 
safety) or to recommend early termination of the study. The 
composition and operation of the IDMC are described in the 
IDMC charter. 
A statistical analysis center (a Contract Research Organization 
not otherwise involved with study conduct or statistical 
analysis) will generate unblinded analysis reports, exclusively 
for review by the IDMC throughout the trial period. 
An Ophthalmology Safety Board (OSB) composed of two 
independent ophthalmologists will review and evaluate − in a 
blinded fashion − any new or suspected cases of macular edema. 
The composition and operation of the OSB are described in the 
OSB charter. 
A MACE adjudication board will review and evaluate in a 
blinded fashion the MACE reported in the study. The selection 
of AEs that will be sent for adjudication will be based on a 
pre-defined list of preferred terms belonging to relevant 
Standardized Medical Dictionary for Regulatory Activities 
(MedDRA) Queries. For each AE sent for MACE adjudication, 
the MACE adjudication board will determine whether the event 
belongs or not to one of the pre-specified categories including 
cardiovascular death, myocardial infarction, and stroke. 
The composition and operations of MACE adjudication board 
are described in the MACE adjudication board charter.

SUB-STUDIES 
Pulmonary function monitoring 
A sub-study assessing DLCO will be conducted in approximately 
400 subjects recruited at approximately 80 selected sites with 
appropriate equipment and experience. With the 1:1 
randomization (20 mg ponesimod or 14 mg teriflunomide), this 
will represent approximately 200 subjects per treatment group.  
Non-conventional MRI techniques 
MTR has better histological specificity than conventional 
T2-weighted MRI. MTR is sensitive to change over time and to 
treatment effects on NAWM and on focal lesions. DIR is a 
method that allows better visualization of grey matter lesions 
than conventional T2-weighted imaging. Both methods can be 
applied in multicenter settings. 
A sub-study using these non-conventional MRI techniques will 
be implemented in approximately 300 subjects recruited at 
selected sites with appropriate equipment and experience.  
Patient preferences 
A sub-study assessing patient preferences in approximately 
360 subjects recruited at selected sites will be conducted using 
an electronic questionnaire. The Multiple Sclerosis Patient 
Preference Questionnaire will be completed at home twice 
during the pre-randomization period (after Visits 1 and 
2 [Screening, Baseline]), and once during the follow-up period 
(Visit 15, FU1). 
Vaccination 
Changes in vaccine-specific antibody titers from pre- to 
post- vaccination will be assessed at the end of the study for 
subjects having received non-live vaccination while on study 
treatment.  
STUDY EXTENSION  
 
Extension study AC-058B303 (separate protocol) 
Subjects who complete the 108-week treatment will be 
proposed to enroll in a non-comparative extension study 
conducted under a separate protocol.

*Data collected in the eCRF 
**Data electronically transferred to sponsor. 
Day 1 (date of randomization visit) is to be used as the reference date for the purpose of calculating the subsequent visit dates (and time windows). 
(1) All pre-randomization assessments performed at Visit 1 (Screening) and Visit 2 (Baseline) may be conducted on days differing from the actual Visit 1 (Screening) 
date defined as the start of screening activities (i.e., signature of the informed consent form) and Visit 2 (Baseline)date defined as the date of baseline EDSS 
assessment. However, all pre-randomization assessments performed at Visit 1 and repeated at Visit 2 (Baseline; e.g., hematology, blood chemistry, urinalysis, 
physical examination, central laboratory, 12-lead ECGs, and SBP/DBP) must be performed at least 7 days after the Visit 1 (Screening) assessments. For women 
of childbearing potential, the serum pregnancy test at Visit 1 (Screening) must be performed at least 3 weeks before the urine pregnancy test performed pre-
randomization at Visit 2.The blood draw at Visit 2 (Baseline) should happen early enough in order obtain the results from the central laboratory and confirm 
the eligibility prior to randomization. 
(2) At every study visit, subjects are reminded to contact their principal investigator / treating neurologist at the clinical site immediately in the event of the 
appearance of any new or worsening neurological symptoms. In addition, the site will contact the subject in between the 12-weekly visits  
(e.g., Visit 6–Week 12, Visit 7–Week 24,…) in order to proactively inquire about any new or worsened neurological symptoms. These telephone calls will be 
conducted either at Weeks 18, 30, 42, 54, 66, 78, 90, and 102 (+/− 7 days), or 6 weeks after the last 12-weekly visit (+/− 7 days). Whenever, between visits, a 
subject experiences any new or worsening neurological symptoms, he/she must contact the principal investigator / treating neurologist, study nurse or clinical 
coordinator as soon as possible in order to complete a relapse assessment questionnaire [see Appendix 17]. 
(3) During pre-randomization, two practice tests and a third test serving as baseline assessment will be performed. Ideally, the three tests should be performed 
≥ 5 days apart (i.e., second test practice ≥ 5 days from first practice test and third test serving as baseline ≥ 5 days from second practice test). The first test 
practice may be done at Visit 1 (Screening), the second test practice may be done at Visit 2 (Baseline) and the third test serving as baseline may be performed 
pre-dose at Visit 3 (Randomization). 
(4) The symptoms scale (with a 24-h recall) will be completed for 7 consecutive days (the day of the visit and the 6 days after the visit). During pre-randomization, 
subjects during Visit 1 (Screening) will be provided with the FSIQ-RMS and will be instructed to complete the symptoms domain  
(i.e., section 1) of the FSIQ-RMS on 7 consecutive days prior to randomization at home (provided no other assessment performed in the meantime exclude the 
subject). Once the results from the laboratory tests confirm the subject’s eligibility, the site coordinator will contact the subject to instruct him/her to start the 
completion of the symptoms domain of the FSIQ-RMS at latest 7 days before the randomization. 
(5) No CGI-C assessment at Baseline. 
(6) Health care resource utilization data, including number of intensive care unit admission for MS relapses and emergency medical services facility visits for MS 
(7) Only for subjects participating in the patient preference substudy. The Multiple Sclerosis Patient Preference Questionnaire will be completed at home twice 
during pre-randomization (after Visits 1 and 2 [Screening and Baseline]). 
(8) Any CXR that has been performed within 90 days prior to screening can be used (in this case, no need to repeat CXR at Screening). In case of re-screening, 
CXR does not need to be repeated if CXR was performed within 90 days prior to the date of re-screening.  
(9) Brain MRI to be performed at any time an opportunistic infection in the central nervous system is suspected. In addition, non-conventional MRI techniques 
(MTR and DIR) will be performed at selected sites only.  
(10) Dermatological examination to be performed by a dermatologist. In case of re-screening, skin examination does not need to be repeated if skin examination 
from initial screening was performed within 90 days prior to the date of re-screening 
(11) Height only at Visit 1 (Screening). 
(12) SBP/DBP: Pre-dose and hourly (+/− 15 min) for at least 4 h post-dose and up to 12 h.

(13) Only pre-dose ECGs at all visits except Day 1 and Week 12. 
(14) Pre-dose and hourly (+/− 15 min) for at least 4 h post-dose and up to 12 h.  
(15) Pre-dose and 3-h (+/− 15 min) post-dose ECGs. 
(16) OCT and/or ophthalmological examination to be performed at any visit in the presence of visual symptoms or findings suggestive of macular edema or active 
uveitis [see Section 5.1.13.7].  
(17) Pulmonary function tests include spirometry to be performed pre-dose in all subjects and DLCO to be performed in a subset of approximately 400 subjects at 
selected sites only.  
(18) In addition, liver tests (ALT, AST, INR, alkaline phosphatase and total bilirubin) at Weeks 6, 8, 10, 14, 16, 18, 20, and, 22 will be collected, sent to, and 
analyzed at the central laboratory. Furthermore, total white blood cell and total lymphocyte counts will be assessed at Weeks 8, 16, and 20. The test window is

*Data collected in the eCRF 
**Electronically transferred to sponsor. 
Day 1 (date of randomization visit) is to be used as the reference date for the purpose of calculating the subsequent visit dates (and time windows). 
 
(1) At every study visit, subjects are reminded to contact their principal investigator / treating neurologist at the clinical site immediately in the event of the 
appearance of any new or worsening neurological symptoms. In addition, the site will contact the subject in between the 12-weekly visits  
(e.g., Visit 6–Week 12, Visit 7–Week 24,…) in order to proactively inquire about any new or worsened neurological symptoms. These telephone calls will be 
conducted either at Weeks 18, 30, 42, 54, 66, 78, 90, and 102 (+/− 7 days), or 6 weeks after the last 12-weekly visit (+/− 7 days). Whenever, between visits, a 
subject experiences any new or worsening neurological symptoms, he/she must contact the principal investigator / treating neurologist, study nurse or clinical 
coordinator as soon as possible in order to complete a relapse assessment questionnaire [see Appendix 17]. 
(2) The symptoms scale (with a 24-h recall) will be completed for 7 consecutive days (the day of the visit and the 6 days after the visit).  
(3) Health care resource utilization data, number of intensive care unit admission for MS relapses and emergency medical services facility visits for MS. 
(4) Only for subjects-participating in the patient preference sub-study. The Multiple Sclerosis Patient Preference Questionnaire will be completed at home during 
follow-up period (before Visit 15 [FU1]). 
(5) In case of premature study drug discontinuation, the chest X-ray at EOT does not need to be performed if the EOT visit occurs within less than 24 weeks of the 
pre-randomization chest X-ray. 
(6) Brain MRI to be performed at any time an opportunistic infection in the CNS is suspected. In addition, non-conventional MRI techniques (MTR and DIR) will 
be performed at selected sites only. Note: in case of premature study treatment discontinuation, the MRI assessment at EOT does not need to be performed if 
the EOT visit occurs within less than 4 weeks of the MRI assessment at Visit 10 (Week 60). 
(7) Dermatological examination to be performed by a dermatologist.  
(8) SBP/DBP: Pre-dose and hourly (+/− 15 min) for at least 4 h post-dose and up to 12 h. 
(9) Pre-dose ECGs at all visits (when applicable) except re-initiation visits. At re-initiation, pre-dose and hourly (+/− 15 min) for at least 4 h post-dose ECGs and 
up to 12 h. 
(10) OCT and/or ophthalmological examination to be performed at any visit in the presence of visual symptoms suggestive of macular edema or active uveitis [see 
Section 5.1.13.7].  
(11) PFTs include spirometry to be performed pre-dose in all subjects and DLCO to be performed in a subset of approximately 400 subjects at selected sites only. 
(12) Serum pregnancy test at FU2. Urine pregnancy test at all other visits. Urine pregnancy tests (performed at home) on a 4-weekly basis between the visits during 
the study and continued after last study drug intake on a 4-weekly basis (+/− 4 days) (performed at home) until 6 weeks after the first of two tests showing 
teriflunomide plasma level < 0.02 mg/L (results of the pregnancy tests to be communicated by telephone call to the principal investigator / treating neurologist). 
At all visits and telephone calls, the methods of contraception will be reviewed and the contraceptive method form entered in the eCRF must be updated as 
applicable. 
(13) Pre- and post-vaccination sampling for vaccine-specific antibody titers for subjects having received non-live vaccination while on study treatment (sub-study)

(14) When possible, collect PK sample upon experiencing SAE. Preferably, sample will be collected pre-dose, as early as possible after SAE onset, and no later 
than 7 days after the last dose of study drug. 
(15) If the subject was not compliant with the accelerated elimination procedure, the procedure must be repeated or missing intakes completed. 
(16) Scheduled study medication dispensing/return procedures may be adapted according to the site practice.  
(17) All AEs and SAEs that occur after signing the Informed Consent Form and up to 30 days after study treatment discontinuation must be reported. 
(18) The EOT visit will take place at Week 108 (or earlier in case of premature discontinuation of study drug). In all cases, the EOT visit should take place 1 day 
after the last dose of study drug but no later than 7 days after the last dose of study drug. 
(19) Unscheduled visits may be performed at any time during the study and may include all or some of the indicated assessments, based on the judgment of the 
investigator. 
(20) Only if no 12-lead ECG is performed at this visit. 
(21) Only at unscheduled visits when the subject meets with the treating neurologist (but not at other unscheduled visits (e.g., conducted for repeat ALT or AST 
testing, repeat PFT testing,…). 
(22) For subjects not continuing in the AC-058B303 extension study, FU2 will be performed 30 to 37 days after last study drug intake. For subjects continuing in 
the AC-058B303 extension study, an abbreviated FU2 will be performed 23 to 37days after last study drug intake, if needed for compliance reasons. 
The abbreviated FU2 should include: Accelerated elimination procedure compliance review, AEs/SAEs, relapse, concomitant medications 
(23) The testing of teriflunomide plasma concentration may be conducted for women of childbearing potential and fertile male subjects, if needed to confirm that 
contraception may be discontinued. Teriflunomide plasma concentration can also be assessed for any subjects not entering the extension study if deemed 
necessary for the subject’s safety, at the investigator’s discretion. Testing must not be conducted earlier than i) 20 weeks after last drug intake if the subject’s 
compliance with the accelerated elimination procedure has been assessed as sufficient [see Section 5.1.14.2]; ii) 35 weeks (i.e., 8 months) after last drug intake 
or EOS, whichever is last, if the subject’s compliance with the accelerated elimination procedure has not been assessed as sufficient. 
(24) Only if the accelerated elimination procedure has been repeated or missing intake was completed after FU1.

BACKGROUND 
1.1 Multiple sclerosis 
Multiple sclerosis (MS) is an inflammatory autoimmune disorder of the central nervous 
system (CNS) and the most common cause of progressive neurological disability in young 
adults [Compston 2008]. This chronic demyelinating disease is characterized by 
heterogeneous clinical expression, an unpredictable course and a variable prognosis. In 
MS, the frequent and major neurological disability has important personal, social, and 
financial consequences for patients, their families, and health care systems. 
1.1.1 Pathogenesis 
Although the etiology of MS is still unknown, it is widely accepted that it is an 
immune-mediated, demyelinating process precipitated by unknown environmental factors 
in genetically susceptible people.  
MS results from a cascade of events involving activation of the immune system, acute focal 
inflammatory demyelination, and axonal loss with limited remyelination, culminating in 
chronic multifocal sclerotic plaques in the brain and spinal cord. 
1.1.2 Clinical course 
The two main clinical features of MS are exacerbations (also called attacks or relapses) 
and progressive loss of neurological function. Relapses are considered the clinical 
expression of acute, inflammatory, focal lesions of the brain or spinal cord, corresponding 
to axonal demyelination, which leads to the slowing or blockade of axonal conduction at 
diverse affected sites of the brain and spinal cord. This inflammatory disease activity may 
translate to a large variety of clinical symptoms and signs and/or acute lesions visualized 
on MRI. The acute MRI lesions may or may not be accompanied by clinical symptoms. 
The progressive loss of neurological function (called progression or accumulation of 
disability) may result from incompletely recovered relapses or may be independent from 
relapses [Lublin 2003]. It is thought to reflect mainly neurodegeneration corresponding to 
demyelination, axonal loss and gliosis. 
The natural history of MS suggests that there are different patterns of disease course 
[Confavreux 2014a, Compston 2008]. In relapsing-remitting MS (RRMS), patients have 
acute exacerbations with full or partial recovery [Lublin 2003] and are otherwise stable 
between exacerbations; this presentation is observed in the majority of MS patients 
(80−85% of the MS population).  
Approximately 65−70% of RRMS patients experience gradual accumulation of disability 
and fewer relapses later in their disease, which evolves into a secondary progressive

MS (SPMS) stage characterized by less inflammatory and more pronounced 
neurodegenerative features. The median time for patients with RRMS to progress into 
SPMS is about 10 years [Noseworthy 2000, Compston 2008]. In primary progressive MS 
(PPMS), patients experience progression of disability from onset (approximately 10−20% 
of patients with MS). In progressive relapsing MS (PRMS) occurring in approximately 
5% of patients with MS, the disability progression starts from the onset of the disease and 
is associated with occasional relapses. 
The classification of MS subtypes and the related terminology has been subject to changes 
over the last two decades. In 1996, the US National Multiple Sclerosis Society (NMSS) 
Advisory Committee on Clinical Trials in Multiple Sclerosis defined the clinical subtypes 
of MS and provided standardized definitions for four MS clinical courses: relapsing-
remitting (RR), secondary progressive, primary progressive (PP), and progressive 
relapsing [Lublin 1996]. The Committee proposed to eliminate the PRMS category since 
it could reflect misclassification of other MS categories (e.g., SPMS without recognition 
of the initial relapsing course), but the term continued to be used by clinicians and in 
clinical trials. In 2011, the NMSS Advisory Committee, also sponsored by the European 
Committee for Treatment and Research in MS, proposed to define the MS course by adding 
modifiers based on disease activity and progression [Lublin 2014]. A patient with RRMS 
who had a new gadolinium-enhancing (Gd+) lesion on a current MRI would be considered 
to be RR–active. Conversely, the term ‘not active’ could be used to indicate a patient with 
a relapsing course but no relapses, Gd+ activity, or new or unequivocally enlarging T2 
lesions during the assessment period. Inclusion of activity as a modifier also allows 
elimination of the PRMS category. A patient with PPMS who has an acute attack (thus 
fulfilling 
prior 
criteria 
for 
PRMS) 
would 
be 
considered 
to 
be  
PP–active. On the other hand, a patient with PPMS with no acute attacks and no MRI 
activity would be considered to be PP–not active. In terms of progressive disease, this new 
classification distinguishes between progressive accumulation of disability from onset, 
which includes non-active PPMS (previously known as PPMS) and active PPMS 
(previously known as PRMS) and progressive accumulation of disability after initial 
relapsing course (SPMS). Further, the term disability progression is only reserved for 
patients who are in the progressive phase of MS, while the term disability accumulation 
refers to worsening in Expanded Disability Status Scale (EDSS) score, which can either be 
due to incomplete recovery from relapses or occurring independent from relapses, 
disregarding the RR or progressive course of MS. 
The Diagnostic Criteria for MS have been modified with the 2010 revised version of 
McDonald Criteria [Polman 2011]. Implementation of these Diagnostic Criteria allows for 
an earlier diagnosis of MS, with equivalent or improved specificity and sensitivity 
compared to the 2005 revision of McDonald Criteria [Polman 2005].

Historically, the term clinically isolated syndrome has been applied to those patients who 
have experienced a single clinical event, who have had other possible diagnoses excluded, 
and who did not fulfill the Diagnostic Criteria for MS [Polman 2005]. With the 2010 
revision of McDonald’s Diagnostic Criteria, clinically isolated syndrome patients with 
clinical and/or MRI signs of dissemination in space and MRI signs of dissemination in time 
are now diagnosed with relapsing MS (RMS). 
1.1.3 Epidemiology 
MS affects an estimated 2−2.5 million people worldwide, of whom approximately 630,000 
are in Europe and 250,000 to 350,000 in the United States [Milo 2010, WHO 2008]. 
The incidence of MS is about 7 cases per 100,000 persons per year. The prevalence rate 
varies between races and geographical latitudes, ranging from 50 to 120 per 100,000 
[Compston 2002, Milo 2010]. The prevalence is highest in Northern Europe, Southern 
Australia, New Zealand and North America. The reason for the changing prevalence with 
geographical latitude is unknown but suggests the existence of environmental factors, in 
addition to genetic factors [Pugliatti 2002, Compston 2008]. The highest prevalence is 
observed in Northern European descendants (Scandinavia and Scotland) [Milo 2010], 
whereas MS is less common in Asian populations [Pugliatti 2002]. 
MS is the most common chronic neurologic disease in adults between 20 and 50 years of 
age with a peak onset of MS in the early thirties. Women are affected approximately twice 
as often as men [Confavreux 2014a]. In 2 to 5% of patients, disease presents before the age 
of 16 [Compston 2002, Renoux 2007].  
1.1.4 Treatment of MS 
Current medical practice encourages early intervention with disease-modifying treatments, 
with the intent of optimizing long-term clinical outcomes [Gold 2012]. 
Key objectives in the management of MS are reducing the rate of relapses and preventing 
or at least delaying disease progression [Gold 2012]. Most of the disease-modifying drugs 
approved for MS have to be administered by injection or infusion (subcutaneous [s.c.], 
intramuscular [i.m.], or intravenous [i.v.] route). Recently, new disease-modifying drugs 
administered 
orally 
have 
been 
approved 
for 
RMS. 
Currently,

1.1.4.1 Injectable disease-modifying therapies 
The following injectable drugs have been approved in at least one country for the treatment 
of MS: 
• Interferon (IFN) β-1a 30 mcg i.m. once weekly (Avonex®) 
• IFN β-1a 22 or 44 mcg s.c. 3 times weekly (Rebif®) 
• IFN β-1b 250 mcg s.c. every other day (Betaferon®, Extavia®) 
• Pegylated IFN β-1a 125 mcg subcutaneously every 2 weeks (Plegridy®) 
• Glatiramer acetate 20 mg s.c. once a day (o.d.) or 40 mg subcutaneously 3 times weekly 
(Copaxone®) 
• Glatiramer acetate 20 mg s.c. o.d. (Glatopa®) 
• Natalizumab 300 mg i.v. every 4 weeks (Tysabri®)

(10 mg/mL) (Lemtrada®)  
Additional injectable drugs are currently in late-stage development for the treatment of 
RMS, including ocrelizumab, daclizumab, and AIN457 (secukinumab).  
1.1.4.2 Orally administered disease-modifying therapies 
Several oral drugs have been approved for MS: 
• Fingolimod 0.5 mg orally o.d. (Gilenya®) 
• Teriflunomide 7 mg, 14 mg o.d. (Aubagio®) 
• Dimethyl fumarate (BG-12) gastro-resistant hard capsules 120/240 mg twice daily 
(Tecfidera®) 
• Cladribine 40 to 100 mg orally per treatment week (Mavenclad®) 
Oral drugs currently in late-stage development for the treatment of RRMS include 
laquinimod [Comi 2012], and a sphingosine 1-phosphate (S1P) receptor modulator, 
RCP1063/ozanimod. Siponimod, another S1P1 receptor modulator, is currently being 
developed for the treatment of SPMS. 
1.2 Sphingosine-1-phosphate receptors  
S1P plays a central role in lymphocyte trafficking [Cyster 2005, Brinkmann 2007, 
Brinkmann 2010, Schwab 2007, and references therein]. S1P is synthesized and secreted 
by many cell types, including platelets, erythrocytes, and mast cells, and elicits a variety of 
physiological responses [Cyster 2005, Alvarez 2007]. Among other effects, lymphocyte 
egress from primary and secondary lymphoid organs is dependent on the S1P1 receptor. 
S1P1 receptor modulators block lymphocyte migration out of lymphoid tissue into the 
lymphatic and vascular circulation, thereby reducing peripheral lymphocyte counts and 
preventing lymphocyte recruitment to sites of inflammation. Following withdrawal of an

S1P1 receptor agonist, the functional lymphocytes return to the circulation from their sites 
of sequestration. Other functions that do not rely on homing mechanisms, such as antibody 
generation by B lymphocytes, first-line immunological protection by granulocytes and 
monocytes, and antigen-dependent T-cell activation and expansion, are not affected by this 
mechanism [Pinschewer 2000].  
S1P itself induces pleiotropic effects, which are mediated by a family of 
five G protein-coupled receptors, S1P1-S1P5, located on endothelial cells, vascular and 
cardiac smooth muscle cells, and cardiac myocytes [Alvarez 2007, Brinkmann 2007, 
Brinkmann 2010]. The first S1P receptor modulator, fingolimod (FTY720, Gilenya®), 
which has been approved by the FDA and the EMA for the treatment of MS, is not selective 
for the S1P1 receptor but interacts with S1P3, S1P4, and S1P5 [Brinkmann 2007, 
Brinkmann 2010].  
1.3 Ponesimod  
Ponesimod, an iminothiazolidinone derivative, is an orally active, selective modulator of 
the S1P1 that induces a rapid, dose-dependent, and reversible reduction in peripheral blood 
lymphocyte count by blocking the egress of lymphocytes from lymphoid organs. T and 
B cells are most sensitive to ponesimod mediated sequestration. In contrast, monocyte, 
natural killer (NK) cell and neutrophil counts are not reduced by ponesimod. The effect of 
ponesimod on circulating effector T cells represents a promising therapeutic approach for 
diseases in which activated T cells play a critical role.  
More detailed information can be found in the Investigator’s Brochure (IB) 
[Ponesimod IB]. 
1.3.1 Nonclinical studies 
The main findings in the nonclinical studies conducted with ponesimod are: 
• Ponesimod causes a rapid and substantial reduction in circulating lymphocytes in rats 
and dogs, which is also rapidly and fully reversible. The effect correlates well with the 
plasma concentration of ponesimod. 
• Studies with ponesimod in animal models of T-cell-mediated diseases, such as MS, 
rheumatoid arthritis, type 1 diabetes and skin hypersensitivity, consistently indicated a 
therapeutic potential of ponesimod at oral doses that lower peripheral blood 
lymphocyte counts.  
• Ponesimod shows an oral bioavailability of 35−74%, low clearance, and a tissue 
distribution greater than total body water in rats and dogs. Plasma protein binding is 
high (≥ 98.9%) in rats, dogs, and humans.

• The metabolism of ponesimod is comparable in rats, dogs, and humans. The main 
metabolite, ACT-338375 (M13), is present in plasma of mice, rats, and dogs at levels 
similar to or higher than steady state exposures in humans at 40 mg/day. 
• Based on available nonclinical data, the potential for drug-drug interactions (DDIs) is 
limited. The metabolite M13 has no liability for causing DDIs via inhibition of 
cytochrome P450 enzymes or transport proteins. M13 is not a time-dependent inhibitor 
of CYP3A4, CYP2D6 or CYP2C9. Neither ponesimod nor the M13 metabolite 
approach plasma concentrations expected to inhibit CYP2C9 or CYP2C19 after daily 
doses of 20 mg at steady state. 
• The main targets for ponesimod-related toxicity after treatment of up to 4 weeks were 
the lung (all species) and the nervous system (clinical signs in dogs). After 13, 26 and 
52 weeks of treatment, the heart and skin were identified as additional target organs in 
dogs. No-observed-adverse-effect levels were established for all toxicologically 
relevant targets in rats, mice, and dogs after 4, 13, 26, and 52 weeks of treatment, and 
resulting safety margins are considered acceptable. 
• Embryo-fetal toxicity studies in rats and rabbits indicated that ponesimod has 
embryotoxic and teratogenic potential. In rat fertility studies, ponesimod had no effects 
on female and male fertility and did not produce any testicular morphologic changes. 
More detailed information can be found in the IB [Ponesimod IB]. 
1.3.2 Clinical studies 
The human clinical experience with ponesimod to date consists of studies assessing single- 
and multiple-dose safety and tolerability, pharmacokinetics (PK) and pharmacodynamics 
(PD) in healthy subjects treated with a single dose of up to 75 mg, or multiple doses of up 
to 100 mg o.d., for up to 22 days, as well as studies in subjects with RRMS treated for up 
to 4 years and in subjects with moderate-to-severe chronic plaque psoriasis treated for up 
to 28 weeks with doses up to 40 mg o.d. A proof-of-concept study (AC-058A200) and 
dose-finding study (AC-058A201) in moderate-to-severe plaque psoriasis and a dose-
finding study in RRMS (AC-058B201) have been completed. An extension study 
evaluating long-term effects of ponesimod in RRMS subjects who completed study AC-
058B201 is ongoing (AC-058B202). Ponesimod may also be investigated in subjects 
suffering from other lymphocyte-mediated diseases. 
For results of the Phase 1 studies and Phase 2 study in chronic plaque psoriasis, please refer 
to the IB [Ponesimod IB]. 
1.3.2.1 Clinical pharmacology 
The PK profile of ponesimod is characterized by low variability. The terminal elimination 
half-life is about 32 h. There is approximately two-fold accumulation of the drug with 
repeated daily oral dosing, and steady state is achieved within 4−5 days. There is a good

correlation between the plasma concentration of ponesimod and the peripheral blood total 
lymphocyte count. Food, age, race or sex do not appear to relevantly affect the PK and PD 
of ponesimod. The PK DDI potential of ponesimod is judged to be low based on current 
nonclinical and clinical data.  
More detailed information can be found in the IB [Ponesimod IB]. 
1.3.2.2 Pharmacodynamics in humans 
Oral administration of ponesimod dose-dependently reduces the circulating lymphocyte 
count in humans. The maximum reduction from baseline of approximately 65–80% is 
achieved after a single dose of ≥ 50 mg, or 40 mg o.d. at steady state. The nadir in 
lymphocyte count is attained within 6−10 h following a given single dose. There is no 
evidence of tachyphylaxis on lymphocyte count. Peripheral blood counts of both T and B 
cells are reduced by ponesimod, while NK cells and neutrophils are not reduced. Food, 
race and gender do not appear to relevantly affect the PD of ponesimod. Upon 
discontinuation of ponesimod, the lymphocyte count generally returns to within the normal 
range within 1 week.  
The magnitude of lymphocyte-count reductions seen with ponesimod in MS subjects was 
consistent with observations made after short-term treatment in healthy subjects. In the 
Phase 2 dose-finding study AC-058B201, at Week 24, the mean reductions from baseline 
in lymphocyte count were 49.8%, 65.3% and 68.6% in the ponesimod 10 mg, 20 mg, and 
40 mg groups, respectively, compared to a mean increase of 3.3% in the placebo group. 
Lymphocyte counts remained stable on treatment and returned to baseline levels within 
1 week following ponesimod treatment discontinuation. 
More detailed information can be found in the IB [Ponesimod IB]. 
1.3.2.3 Efficacy in humans 
Study AC-058B201 was a prospective, multicenter, randomized, double-blind, 
placebo-controlled, parallel-group, dose-finding Phase 2b study, in which efficacy, safety, 
and tolerability of three doses of ponesimod administered for 24 weeks were investigated 
in subjects with RRMS. A total of 464 subjects were randomized (1:1:1:1) to 10, 20, or 
40 mg ponesimod as the capsule formulation, or placebo. Study medication was 
administered orally o.d., with a starting dose of 10 mg o.d. in all ponesimod arms and with 
up-titration to 20 and 40 mg on Days 8 and 15, respectively. 
Treatment with ponesimod at doses of 10, 20, and 40 mg was associated with a statistically 
significant decrease in the cumulative number of new T1 Gd+ lesions at Weeks 12, 16, 20, 
and 24 (primary endpoint) compared to placebo. The observed effect was dose-dependent, 
reaching a risk reduction vs placebo of 77% (p < 0.0001), 83% (p < 0.0001) and 43% 
(p < 0.05) in the 40, 20, and 10 mg groups, respectively vs placebo.

The study was not powered to detect a significant effect of ponesimod on clinical endpoints 
like aggregate Annualized Relapse Rate (ARR) or time to first confirmed relapse. 
Treatment with ponesimod was associated with a reduction in the aggregate ARR up to 
Week 24. The ARR reduction in the 40 mg dose group was 52% (0.251 vs 0.525 for 
placebo; nominal p < 0.05), compared with 21% and 37% in the 20 mg and 10 mg groups, 
respectively. Treatment with ponesimod was associated with an increase in time to first 
confirmed relapse on treatment. The hazard ratio for subjects treated with 40 mg 
ponesimod was 0.42 (95% confidence interval [CI] 0.20–0.87, p = 0.0189). In the 20 mg 
and 10 mg groups, the hazard ratio was 0.79 (95% CI 0.43, 1.45) and 0.64 (95% CI 0.33, 
1.22), respectively. 
Study AC-058B202 is a randomized, double-blind, parallel-group extension to study 
AC-058B201, in which the long-term safety, tolerability, and efficacy of 10, 20, and 
40 mg/day ponesimod in subjects with RRMS are being investigated. Subjects who 
completed 24 weeks of treatment with ponesimod in the core study were offered to 
continue treatment with ponesimod. Subjects who completed 24 weeks of treatment with 
placebo were randomized in a 1:1:1 ratio to either 10, 20 or 40 mg ponesimod daily.  
The results from an interim analysis of study AC-058B201/B202 with cut-off date of 
31 October 2014 have shown sustained low rates of MRI and clinical disease activity with 
dose-dependent effects on relapse rate and disability accumulation. The model-adjusted 
ARR observed with ponesimod 20 mg was approximately 0.170, a rate similar to that 
observed with the 1.25 mg dose of fingolimod after 5 years in the Phase 2 extension study 
[Izquierdo 2013]. There was also a dose-dependent effect of ponesimod on disability 
accumulation, with a decreasing risk of 6-month confirmed disability accumulation (CDA) 
and lower rates of EDSS worsening observed with increasing doses of ponesimod.  
More detailed information can be found in the IB [Ponesimod IB]. 
1.3.2.4 Safety and tolerability 
Clinical studies to date have identified transient changes in heart rate (HR) and 
atrioventricular (AV) conduction as the most prominent safety-related signal with 
ponesimod. Oral doses of ponesimod resulted in dose-dependent sinus rate reductions in 
all treated subjects; the changes were transient and resolved largely within 6−10 h after 
dosing. In some subjects, these HR reductions were accompanied by a transient effect on 
AV conduction with prolongation of the PR interval on the electrocardiogram (ECG) and, 
occasionally, second degree AV-block. The effects on HR and AV conduction diminish 
with repeated administration of ponesimod, indicating desensitization. To minimize the 
first-dose effects on HR and AV conduction, a dose up-titration regimen was successfully 
tested and is implemented in current clinical trials.

Difficulty in inspiration (dyspnea) and related pulmonary function test (PFT) changes have 
also been detected in humans. Mild transient dyspnea/cough was noted frequently 2−6 h 
after an oral dose of 40 mg or higher, and was associated with a clinically relevant forced 
expiratory volume in 1 second (FEV1) decrease from baseline. Symptoms resolved 
spontaneously upon discontinuation of treatment with ponesimod, and PFTs returned to 
baseline upon drug discontinuation. Data from an interim analysis of the long-term 
extension study AC-058B201/B202 with a cut-off date of 31 October 2013 showed that 
dose-dependent decrease in FEV1 remained stable in patients treated with ponesimod for a 
median of more than 3 years and remains reversible over the long term. 
Elevations of aspartate transaminase (AST) and/or alanine aminotransferase (ALT) 
without any bilirubin increase have been noted with ponesimod; they have been reversible 
upon discontinuation of dosing. The changes were asymptomatic.  
Individual cases of macular edema associated with changes in visual acuity have been 
observed in subjects treated with ponesimod. These events resolved upon discontinuation 
of ponesimod. 
Nonclinical safety testing of ponesimod indicates an embryotoxic and teratogenic 
potential. Pregnant or lactating women are excluded from clinical trials, and women of 
childbearing potential (WOCBP) must use reliable methods of contraception and must not 
become pregnant during a clinical study and for at least 30 days after study drug 
discontinuation. A hormonal contraceptive is allowed as one of the required methods of 
contraception, as the PK profile of hormonal contraceptives has been shown not to be 
substantially altered in the presence of ponesimod.  
More detailed information can be found in the IB [Ponesimod IB]. 
1.3.3 Comparator drug 
Teriflunomide has been chosen as the active comparator. Teriflunomide is indicated for the 
treatment of patients with relapsing forms of MS [Aubagio® USPI, Aubagio® SmPC].  
Teriflunomide is a selective and reversible inhibitor of mitochondrial dihydroorotate 
dehydrogenase, an enzyme that is necessary for pyrimidine synthesis. The inhibition of 
pyrimidine synthesis results in a cytostatic effect on peripheral T- and B-lymphocytes, 
decreasing the number of activated lymphocytes that enter the CNS, thus decreasing the 
inflammatory response known to be present in the CNS in patients with MS. Teriflunomide 
is the active metabolite of leflunomide, marketed as ARAVA® for the treatment of 
rheumatoid arthritis since 1998.  
Teriflunomide is administered orally o.d. at the doses of 7 and 14 mg in the USA and 14 mg 
in EU and other countries such as Australia. The plasma levels of teriflunomide circulating

at the dose of teriflunomide of 14 mg/day are comparable to the circulating levels of 
teriflunomide when leflunomide is given at the recommended dose of 20 mg/day. 
Efficacy of Aubagio® was established in two pivotal placebo-controlled trials that enrolled 
2257 patients with RMS (TOWER and TEMSO) [Confavreux 2014b, O’Connor 2011]. In 
the TEMSO study, teriflunomide reduced the ARR (0.54 for placebo vs 0.37 for 
teriflunomide at either 7 or 14 mg), with relative risk reductions of 31.2% and 31.5%, 
respectively (p < 0.001 for both comparisons with placebo). Consistent results were 
obtained in the TOWER study. Compared to placebo, only teriflunomide at the dose of 14 
mg significantly reduced the risk of confirmed accumulation of disability in TEMSO (HR 
0.70 [95% CI (0.51–0.97)]) and in TOWER (HR 0.68 [95% CI (0.47-1.00)]). Both doses 
were also shown consistently superior to placebo on a range of MRI endpoints in the 
TEMSO study. 
In the clinical studies with teriflunomide in patients with RRMS, the incidence of serious 
adverse events (SAEs) was similar among the teriflunomide group and placebo-treated 
patients. The most common adverse events (AEs) associated with teriflunomide in RRMS 
patients included increased ALT levels, alopecia, diarrhea, influenza, nausea and 
paresthesia. Severe liver injury including fatal liver failure has been reported in patients 
treated with leflunomide. As a similar risk would be expected for teriflunomide, it is 
recommended to monitor ALT levels at least bi-weekly for 6 months after starting 
treatment; teriflunomide is contraindicated in patients with severe hepatic impairment and 
patients with pre-existing acute or chronic liver disease should not be treated with 
teriflunomide.  
Based on animal data, teriflunomide may cause major birth defects if used during 
pregnancy. Pregnancy must be excluded before starting treatment with teriflunomide, and 
teriflunomide is contraindicated in pregnant women or WOCB who are not using reliable 
methods of contraception.  
Teriflunomide is eliminated slowly from the plasma. Without an accelerated elimination 
procedure, it takes on average 8 months from discontinuing the drug to reach plasma 
concentrations less than 0.02 mg/L, although because of individual variations in drug 
clearance it may take as long as 2 years. An accelerated elimination procedure must be 
used after study drug discontinuation [see Section 5.1.14]. 
More detailed information can be found in the prescribing information [Aubagio® USPI, 
Aubagio® SmPC].  
Demonstration of superiority over teriflunomide in terms of ARR is clinically relevant, as 
it would provide evidence of significant benefit of the new investigational drug compared 
to a world-wide approved, effective, first-line oral therapy.

1.4 Purpose and rationale of the study 
The central role of S1P in lymphocyte trafficking and the ability of an S1P receptor 
modulator to reduce the availability of circulating lymphocytes is a promising therapeutic 
approach for autoimmune diseases [see Section 1.2]. The non-selective S1P receptor 
modulator fingolimod has been proven effective in the treatment of MS, leading to an 
approval for the treatment of RMS. 
The Phase 2 dose-finding study AC-058B201 demonstrated dose-dependent effects of the 
selective and orally active S1P1 receptor modulator ponesimod on relevant MRI variables, 
and on the lymphocyte count reduction [see Section 1.3.2.2]. Altogether, the above 
elements support further development of ponesimod for the treatment of RMS and suggest, 
if this profile is confirmed in this study, that ponesimod may offer a new type of selective 
immunomodulation for the treatment of RMS. 
This Phase 3 study is considered pivotal for the registration of ponesimod in the indication 
of relapsing forms of MS. The purpose of this study is to confirm the efficacy seen in the 
Phase 2 studies and to further evaluate the safety and tolerability of ponesimod in subjects 
with RMS. Ponesimod will be compared to the active comparator teriflunomide for its 
ability to reduce relapse rate, slow disability accumulation and reduce brain volume loss as 
detected by MRI during an overall treatment period of 108 weeks.  
The present study was designed in accordance with the 2006 CHMP guidance for product 
development in MS [EMA 2006] and its draft revision, adopted by the CHMP for release 
for public consultation [EMA 2012].

OVERALL STUDY DESIGN AND PLAN 
This is a prospective, multicenter, randomized, double-blind, active-controlled, 
parallel-group, Phase 3, superiority study. The study is designed to compare the efficacy, 
safety, and tolerability of ponesimod 20 mg vs teriflunomide 14 mg in adult subjects with 
relapsing forms of MS. 
Approximately 1100 subjects will be randomized in two groups in a 1:1 ratio to receive 
ponesimod 20 mg (approximately 550 subjects) or teriflunomide 14 mg (approximately 
550 subjects). Randomization will be stratified by use of MS disease-modifying treatment 
in the last two years prior to randomization (yes, no) and by baseline EDSS score  
(EDSS ≤ 3.5, EDSS > 3.5). 
The study will be conducted at approximately 200 sites in 25 countries in North America, 
South America, Eastern and Western Europe, and Pacific. Randomization will proceed 
until the required number of subjects has been reached. Any eligible subject in screening 
at the time of randomization of the 1100th subject will be recruited. It will be competitive 
across participating sites. The trial will include up to a maximum of 15% of subjects with 
SPMS. Screening of the subjects with SPMS will be permitted until a maximum of 
165 subjects with SPMS have been randomized. Any eligible subject with SPMS in 
screening at the time of randomization of the 165th subject with SPMS will be recruited. It 
is permitted to re-screen subjects once [see Section 8]. Actelion may wish to replace sites 
with no subject enrollment. 
Subjects who have completed treatment until Week 108 will be proposed to enroll in an 
extension study with ponesimod, conducted under a separate protocol. Those who 
discontinue study drug prematurely will not be eligible for the extension study. 
3.1 Study periods 
The organization of the different study periods is shown in Figure 1, Figure 2, and Figure 3. 
The study consists of the following periods: 
3.1.1 Pre-randomization period  
This period starts up to 45 days before randomization at the time of the signature of the 
Informed Consent Form (ICF) and ends with subject’s randomization. It includes Visit 1 
(Screening) and Visit 2 (Baseline).

3.1.2 Treatment period 
This period consists of a double-blind treatment period from Day 1 to Week 108. This 
period starts on the day of randomization immediately after the 1st dose of study drug intake 
(Visit 3−Day 1 of the study) and continues until the premature discontinuation of study 
drug or the scheduled End-of-Treatment (EOT) at Week 108.  
EOT visit: The EOT visit will take place at Week 108 or earlier in case of premature 
discontinuation of study drug. In all cases, the EOT visit should preferably take place 1 day, 
and not later than 7 days, after the last dose of study drug.  
3.1.3 Post-treatment period and End-of-Study 
This period starts immediately after the last dose of study drug and ends when 
End-of-Study (EOS) visit has been completed. It comprises the post-treatment safety 
follow-up (FU) period and if applicable, the post-treatment observation period (PTOP). 
3.1.3.1 Post-treatment safety follow-up period 
All subjects will enter the safety FU period: 
• For subjects who enter the extension study, the safety FU period lasts for 14–37 days 
after the last dose of study drug and includes a safety FU visit (FU1) 14–22 days after 
the last dose of study drug. If compliance to the teriflunomide accelerated elimination 
procedure is confirmed at FU1, the subjects will then be enrolled in the extension study. 
However, if compliance to the teriflunomide accelerated elimination procedure is not 
confirmed at FU1, the procedure may be repeated or missing intakes completed. In such 
cases an abbreviated FU2 will be conducted 23–37 days after the last dose of study 
drug. Provided sufficient compliance with the accelerated elimination procedure of 
teriflunomide [see Section 5.1.14.2] is documented, subjects will then be enrolled in 
the extension study.

• For subjects who do not enter the extension study, the safety FU period lasts for 30 days 
after the last dose of study drug and includes two safety FU visits (FU1, FU2) at 14–
22 and 30–37 days after the last dose of study drug, respectively.

3.1.3.2 Post-treatment observation period  
Subjects who prematurely discontinue study treatment will enter the PTOP, which lasts 
from the last dose of study drug until 108 weeks after randomization (i.e., planned EOT 
period). The PTOP includes an abbreviated schedule of assessments at the time of the 
originally scheduled 12-weekly visits. The safety FU period lasts for 30 days after the last 
dose of study drug and includes two safety FU visits (FU1, FU2).

3.1.4 End-of-Study  
For an individual subject, EOS is reached when treatment, safety FU, and, if applicable, 
PTOP have been completed:  
• For subjects who completed the 108-week treatment period and enter the extension 
study, the EOS visit corresponds to FU visit (FU1) conducted 14–22 days after the last 
study drug dose or to the abbreviated FU2 visit conducted 23–37 days after the last 
study drug dose.  
• For all other subjects, the EOS visit corresponds to the 30-day FU visit (FU2) or to the 
last visit of PTOP (i.e., Week 108 Visit of the PTOP), whichever is last.

3.1.6.1 Pulmonary function monitoring (DLCO) 
A sub-study assessing the diffusing capacity of the lungs, measured using carbon monoxide 
(DLCO), will be conducted in approximately 400 subjects at selected sites with appropriate 
equipment and experience. All subjects recruited at the selected sites will be proposed to 
participate in the sub-study. 
3.1.6.2 Non-conventional MRI techniques 
Magnetization transfer ratio (MTR) has better histological specificity than conventional 
T2-weighted MRI. MTR seems to be sensitive to disease-related changes over time and to 
treatment effects on normal appearing white matter (NAWM) and on focal lesions. Double 
inversion recovery (DIR) is a method that allows better visualization of grey matter lesions 
than conventional T2-weighted imaging. Both methods can be applied to multicenter 
settings. 
A sub-study using these non-conventional MRI techniques will be implemented in 
approximately 300 subjects recruited at selected sites with appropriate equipment and 
experience. All subjects recruited at the selected sites will be proposed to participate in the 
sub-study.  
3.1.6.3 Patient Preferences 
The overall purpose of this sub-study is to capture patient preferences for selected treatment 
outcomes for use as an additional input to healthcare decisions. An increased understanding 
of individual values and preferences is the basis for shared decision-making, which in turn 
encourages patient compliance and health outcomes [Bowling 2001, Coyle 2001]. Patient 
preferences will be captured using a multi-criteria analysis model, Measuring 
Attractiveness by a Categorical Based Evaluation Technique (MACBETH). MACBETH 
uses a non-numerical questioning procedure to collect preference data. The responses are 
converted, by mathematical programming, to quantitative scores, thus allowing the 
construction of value function curves and the calculation of weights [Bana E Costa 1999, 
Fasolo 2014]. 
The sub-study will include a subgroup of approximately 360 patients who will be asked to 
complete the MS Patient Preference Questionnaire developed by Actelion [Appendix 14] 
at three different timepoints (twice during pre-randomization period [after Visits 1 and 2 
(Screening, Baseline)], and once during the follow-up period [Visit 15, FU1]). The 
questionnaire will be administered in electronic format and will assess the patient 
preferences for nine outcomes including frequency of relapses, worsening of disability and 
specific adverse outcomes.  
This sub-study has the following objectives: 1) To describe the value judgments of MS 
subjects within a clinical trial using the MACBETH methodology; 2) To assess the stability 
of MS subjects’ value judgments over two timepoints; 3) To describe the impact of

treatment on the preferences of MS subjects; 4) To describe the relationship between 
demographics, disease characteristics, previous medical history and elicited preferences 
among MS subjects at all timepoints; 5) To construct a treatment-decision model using the 
elicited preference data; and 6) To assess the comprehension and ease of use of the 
preference elicitation instrument. 
3.1.6.4 Vaccination 
Changes in vaccine-specific antibody titers from pre- to post-vaccination will be assessed 
at the end of the study for subjects having received non-live vaccination while on study 
treatment. 
3.1.7 Extension study AC-058B303 (separate protocol) 
Subjects who complete the 108-week treatment period will be proposed to enroll in a non-
comparative extension study with ponesimod treatment conducted under a separate 
protocol.  
3.2 Study design rationale 
This Phase 3 study is intended as pivotal for the registration of ponesimod for the treatment 
of relapsing forms of MS. This study is designed to assess superiority of ponesimod vs 
teriflunomide in reducing ARR in subjects with RMS. The design of this active-controlled 
study meets the requirements laid out by the relevant CHMP guideline [EMA 2006]. 
During the study, several decisions and assessments will have to be performed. In order to 
limit the considerable risk of bias, a double-blind design is warranted.  
With the availability of efficacious disease-modifying treatments, long-term 
placebo-controlled trials have become increasingly difficult to conduct in RMS. In order 
to evaluate the benefit/risk ratio of a new treatment, active-control parallel-group trials 
comparing the new treatment to an already approved treatment are recommended. In this 
context, a superiority trial remains the most reliable means of efficacy demonstration.  
Given the low ARR observed in RMS, a trial involving a large number of subjects treated 
for a 108-week duration is considered a minimum condition to observe a sufficient 
proportion of subjects experiencing relapses and allow for the demonstration of efficacy 
on ARR. 
The size and scope of the resulting safety database for all subjects treated with ponesimod 
at the time of marketing authorization application is anticipated to meet the requirements 
of the ICH [ICH E1A 1995] and CHMP guidelines [EMA 2006; EMA 2012].

3.3 Site personnel and their roles 
In order to maintain the blind [see Section 5.1.5] throughout the study and to facilitate the 
performance of efficacy and safety assessments required by the protocol, it is essential that:  
• The site personnel have the appropriate medical expertise to perform these assessments; 
• The roles are defined clearly upfront. 
It is recommended that the designated personnel remain unchanged throughout the entire 
course of the study and that an adequately trained back-up be designated to perform the 
assessments in case of absence of any of the staff listed below. 
For each site, the study staff will consist of:  
• A principal investigator 
• A treating neurologist (who may be the principal investigator)# 
• An efficacy assessor#  
• A first-dose administrator# 
• A clinical coordinator/study nurse (if required) 
• MRI staff 
• A radiologist/neuroradiologist 
• An ophthalmologist 
• A pulmonary function laboratory technician or expert 
• A pulmonologist (only at sites participating in the DLCO sub-study)  
• A dermatologist. 
# The roles of treating neurologist, efficacy assessor and first-dose administrator are 
irreconcilable and must be assumed by three distinct physicians.  
3.3.1 Principal investigator  
The principal investigator must be an experienced neurologist or must name a 
sub-investigator who is an experienced neurologist. The principal investigator is 
responsible for the overall conduct of the study at the site. It is her/his responsibility to 
assign appropriate personnel to the protocol-requested assessments (including safety and 
efficacy) and define their roles. This includes the supervision of any external facility 
delegated with any study procedure/assessment for a subject. The principal investigator 
oversees the accrual of appropriate subjects, the conduct of the study according to the trial 
protocol, and the collection of the required data. 
3.3.2 Treating neurologist 
The treating neurologist is an experienced neurologist who may be the principal 
investigator. The treating neurologist is responsible for subject clinical care and 
management, e.g., eligibility evaluation, supervision of study drug administration,

assessing and reporting MS relapses on the specific MS relapses pages of the electronic 
case report form (eCRF) [see Section 7.2.2 and Section 10.1.6], monitoring of safety 
including recording and treating of AEs (with the exception of AEs with onset after study 
drug intake and resolution prior to discharge from cardiac monitoring on Day 1 or on the 
first day of re-initiation of study drug when post-dose monitoring is required, which will 
be recorded by the first-dose administrator), physical examination, routine laboratory 
results (with the exception of WBC and lymphocyte counts), concomitant medications, 
blood pressure (BP), and ECGs (with the exception of BP and ECG on Visit 3 [Day 1] or 
on first day of re-initiation of study drug when post-dose monitoring is required, which 
will be performed by the first-dose administrator). Depending on the site setting, all BP and 
ECG assessments required by the protocol during the study may be conducted by the first-
dose administrator [see Section 3.3.4]. The treating neurologist will not perform EDSS / 
FS assessment and will not alter the EDSS or FS scores obtained by the efficacy assessor. 
The treating neurologist will not have access to MRI throughout the study, unless necessary 
for safety reasons.  
It is the responsibility of the treating neurologist to explain the study in all its aspects to 
the subject and obtain her/his informed consent. The treating neurologist will be 
responsible for emphasizing the need for reliable contraception methods and explaining 
such methods to the female participants who are WOCBP and for explaining to the fertile 
male participants the need for using condoms and the need for their female partners of 
childbearing potential to use reliable methods of contraception for the period defined in 
this protocol [Section 4.5].  
The treating neurologist is responsible for the medical management of the subject 
experiencing cardiac events of clinical concern occurring at any time during the study 
treatment and not already evaluated by the first-dose administrator. In these events, the 
treating neurologist may consult with the first-dose administrator and/or a cardiologist. 
In case of acute cardiac events, she/he may refer the subject to a cardiologist to receive 
emergency care and treatment. 
The same physician must maintain the role of the treating neurologist for a given subject 
throughout the study. A back-up treating neurologist may conduct a subject study visit only 
if the primary treating neurologist is not available.

3.3.3 Efficacy assessor 
The efficacy assessor is a physician with clinical experience in the medical treatment and 
care of patients with MS. She/he will perform the detailed neurological examination for 
obtaining the EDSS / Functional system (FS) scores using the “Neurostatus” scoring 
documents [see Appendix 2] according to the protocol schedule, as well as EDSS/FS scores 
at every unscheduled visit for confirmation of relapse. If other trained and certified 
personnel participate in EDSS/FS scoring, they must not be involved in the clinical care 
and management of the study subject.  
Throughout the study, the efficacy assessor must remain unaware of AEs, concomitant 
medications, BP, ECG measurements, MRI and laboratory results, and any other data that 
have the potential to reveal the treatment assignment, in order to avoid potential bias due 
to unblinding. For that reason, all other members of the study staff, as well as the study 
subjects, must be instructed not to discuss clinical findings or safety issues with the efficacy 
assessor.  
To ensure consistency across sites, the efficacy assessor must be trained and certified on 
EDSS/FS scoring prior to enrollment of the first subject at the study site. Through this 
training, the efficacy assessor will become familiar with the EDSS/FS scoring and 
“Neurostatus” scoring documents using an interactive “Neurostatus” Training DVD-ROM 
that will be provided to the site. Certification, consisting of the “Neurostatus e-Test” web-
based interactive test, will be assessed prior to enrollment of the first subject at the study 
site and every 2 years thereafter. 
The same physician should preferably maintain the role of efficacy assessor for a given 
subject throughout the study. A back-up efficacy assessor may conduct neurological 
examination and EDSS/FS scoring if the primary efficacy assessor is not available. This 
back-up efficacy assessor must be trained and certified in EDSS/FS scoring (see above) 
and capable to ensure consistency in EDSS/FS scoring with the primary efficacy assessor.  
The efficacy assessor may be in charge of administering the MSFC test.  
3.3.4 First-dose administrator 
The first-dose administrator must be a physician who is experienced in making health care 
decisions based on ECG interpretation reports provided in a timely manner by the central 
ECG laboratory, and experienced in the evaluation of BP and signs or symptoms. If the 
first-dose administrator is adequately trained and experienced in cardiology, she/he will 
make health care decisions solely based on her/his own interpretation of the ECG (i.e., in 
the case where the reading of the ECGs by the central ECG laboratory is not provided to 
the first-dose administrator in a timely manner).

She/he is responsible for conducting all BP and ECG assessments requested by the protocol 
at Visit 3 (Day 1) and at visits for re-initiation of study drug when post-dose monitoring 
will be required. This includes the close monitoring of the subject during the first 4 h and 
up to 12 h following study drug intake. While the exams themselves may be performed by 
a delegate (e.g., a study nurse), the review and interpretation must be performed by the 
physician. She/he will independently assess eligibility for discharge or continued subject 
management on Visit 3 and on visits for re-initiation of study drug when post-dose 
monitoring will be required [see Sections 5.1.9, 5.1.10, and 5.1.11]. The confirmation of 
discharge of the subject will be documented in the source documents. Depending on the 
setting at the site, the first-dose administrator may also be responsible for the conduct of 
all BP and ECG assessments requested by the protocol during the study. Depending on the 
setting at the site, the study drug administration at Visit 3 (Day 1) or at visits for 
re-initiation of study drug when post-dose monitoring is required, may be performed under 
the supervision of the treating neurologist. In this instance, the subject must rapidly be 
transferred under first-dose administrator supervision for close post-dose monitoring. 
On Day 1 and on the first day of re-initiation of study drug when post-dose monitoring is 
required, significant findings, which in view of the first-dose administrator meet the 
definition of AE, have an onset after the study drug intake, and are resolved at the time of 
discharge of the subject from the cardiac monitoring, must be recorded directly on the 
Adverse Event page of the separate eCRF by the first-dose administrator/delegate. These 
AEs will not be visible to any of the blinded study personnel at the study site. All other 
significant findings on Day 1 and on the first day of re-initiation of study drug when 
post-dose monitoring is required that are not resolved at the time of discharge of the subject 
from the cardiac monitoring or with an onset on any other day, which in view of the 
first-dose administrator meet the definition of AEs, must be reported to the principal 
investigator / treating neurologist, who will record these events on the AE page of the 
eCRF.  
The 3-h PK sample on Day 1 or on the first day of re-initiation of study drug when 
post-dose monitoring is required should be taken by the first-dose administrator, the 
first-dose administrator nurse or another person not involved in the clinical care and 
management of the study subject. 
Any cardiac events of potential clinical concern on Day 1 and on the first day of 
re-initiation of study drug when post-dose monitoring is required must be assessed by the 
first-dose administrator for seriousness. In addition, the first-dose administrator should 
determine the need for medical management and assist the treating neurologist in deciding 
what actions should be taken on study treatment, if any. In these events, the first-dose 
administrator may consult with a cardiologist. In case of acute cardiac events, and if the 
first-dose administrator is not adequately trained and experienced in cardiology and is not

equipped to provide emergency treatment, she/he will refer the subject to a cardiologist to 
receive emergency care and treatment. 
Any AEs with onset on Day 1 or on the first day of study drug re-initiation of study drug 
when post-dose monitoring is required leading to the premature discontinuation of study 
drug must be reported by the first-dose administrator to the principal investigator / treating 
neurologist. Similarly, any SAEs with onset on Day 1 or on the first day of study drug re-
initiation of study drug when post-dose monitoring is required must be reported by the 
first-dose administrator to the principal investigator / treating neurologist.  
The first-dose administrator must ensure that blinded study personnel at the study site, such 
as the treating neurologist and the efficacy assessor, clinical coordinator / study nurse, and 
other personnel involved in the clinical care and management of study subject, do not have 
access to Day 1 or day of re-initiation of study drug post-dose BP assessment, or ECG 
interpretation reports or to AEs with onset after the study drug intake on Day 1 or on the 
first day of re-initiation of study drug when post-dose monitoring is required, and resolved 
at the time of discharge of the subject from the cardiac monitoring on that same day. When 
the exams themselves are performed by a delegate (e.g., a study nurse), this delegate must 
not be involved in the clinical care and management of the study subject (i.e., cannot be 
the clinical coordinator / study nurse of the study [see Section 3.3.5]).  
In case the first-dose administrator is responsible for conducting all BP and ECG 
assessments requested by the protocol during the study, he/she will report to the principal 
investigator / treating neurologist any significant findings in BP or ECGs which in his/her 
view meet the definition of an AE (with the exception of BP and ECG on Visit 3 [Day 1] 
or on first day of re-initiation of study drug when post-dose monitoring is required, which 
will be reported by the first-dose administrator as explained above). These must then be 
reported and recorded on the AE page of the eCRF by the principal investigator / treating 
neurologist. 
3.3.5 Clinical coordinator / study nurse 
Depending on the organization of the investigational site, a clinical coordinator / study 
nurse may be required to assist the principal investigator / treating neurologist in all aspects 
of subject’s management. She/he will be responsible for scheduling visits and assessments 
as planned in the study protocol, recording concomitant medications, maintaining source 
documentation, and transcription of data into the eCRF. She/he will instruct the subjects 
on study drug administration, and collect, process, and send all blood and urine samples to 
the central laboratory. Additionally, she/he may be responsible for coordinating the 
conduct of: 
• MRI 
• PFTs

• Ophthalmological and cardiac examination (except cardiac assessment on Day 1 and 
on day of re-initiation of study drug when post-dose monitoring is required [see Section 
3.3.4]) 
• MS Functional Composite (MSFC) score 
• Symbol Digit Modalities Test (SDMT) 
• Patient-Reported Outcome (PRO) instruments 
• Fatigue Symptom and Impact Questionnaire-RMS (FSIQ-RMS) 
• 36-Item Short Form Health Survey version 2 (SF-36v2™) 
• MS Patient Preference Questionnaire (if applicable) 
• Patient’s Global Impression of Severity (PGI-S) of Fatigue 
• Work Productivity and Activity Impairment: MS (WPAI:MS). 
In the absence of a clinical coordinator / study nurse, the above tasks will be performed by 
the principal investigator or a co-investigator. 
3.3.6 MRI staff 
The MRI staff will be responsible for performing the MRI investigations according to the 
study MRI manual (separate document). Original data will be exported to the Medical 
Image Analysis Center (MIAC), c/o University Hospital Basel, Switzerland, and primary 
data will be stored at the study site.  
3.3.7 Local neuroradiologist/radiologist 
The local neuroradiologist will review the MRI images for safety purposes and will inform 
the principal investigator / treating neurologist of any findings of concern for the subjects’ 
safety, including non-MS related findings detected on the MRI scan. She/he will not 
communicate any efficacy-related MRI results (e.g., lesion counts) to study staff or to the 
subject, unless deemed necessary for maintaining safety of the subject. Significant 
findings, which, in view of the local neuroradiologist, meet the definition of an AE must 
be assessed for seriousness, reported to the principal investigator / treating neurologist and 
recorded on the AE page of the eCRF. In the event of safety findings of potential clinical 
concern observed on the MRI scans at any visit during the study, the local neuroradiologist 
will conduct further examination, as per local standard practice, to rule out or confirm the 
diagnosis. She/he may support the principal investigator in making a decision on eligibility 
of the subject prior to randomization by reviewing historical MRI used to assess the 
eligibility of the subject in the study (i.e., active disease evidenced by one or more Gd+ 
lesion[s] of the brain on an MRI performed within 6 months prior to randomization). 
The local radiologist will review the chest X-ray (CXR) images. At Visit 1 (Screening), 
the local radiologist will assess CXRs in order to exclude any subject with findings 
suggestive of active or latent tuberculosis (TB); any CXR that had been performed within 
90 days prior to screening can be used; if available, there is no need to repeat CXR at

Screening). At EOT, the local radiologist will assess CXRs in order to characterize any 
pulmonary structural changes that could have occurred during treatment. She/he will 
inform the principal investigator / treating neurologist of any findings of concern for the 
subjects’ safety. Significant findings, which, in view of the local radiologist, meet the 
definition of an AE, must be reported to the principal investigator / treating neurologist and 
recorded on the AE page of the eCRF.  
Depending on site setting, the same local radiologist may review MRI images and CXR 
images or a local radiologist may review MRI images and another local radiologist may 
review CXR images. 
3.3.8 Ophthalmologist 
The ophthalmologist will review and interpret the ophthalmological examinations and 
optical coherence tomography (OCT) assessments as scheduled in the study protocol 
[see Section 7.3.9 and 7.3.10]. In the event of suspected clinically significant findings (e.g., 
macular edema), an unscheduled OCT examination should be performed by the 
ophthalmologist, and the principal investigator / treating neurologist will be notified for 
reporting of an AE. In the event of findings observed at any visit during the study, the 
ophthalmologist will conduct further examination, as per local standard practice, to rule 
out or confirm the diagnosis. 
3.3.9 Pulmonary function laboratory technician or expert  
The PFTs must be performed by experienced staff, such as a pulmonary function technician 
or expert, according to the American Thoracic Society (ATS) / European Respiratory 
Society (ERS) guidelines [Miller 2005a].  
3.3.10 Pulmonologist 
At sites participating in the DLCO sub-study, a pulmonologist or a physician adequately 
trained in respiratory medicine will review DLCO results. If clinically significant alterations 
in DLCO variables indicating a pulmonary condition that could result in increased risk for 
the subject are observed, she/he may be prematurely discontinued from the study drug at 
the discretion of the principal investigator / treating neurologist. Significant findings, 
which in view of the pulmonologist meet the definition of an AE, must be reported to the 
principal investigator / treating neurologist and recorded on the AE page of the eCRF. In 
the event of findings observed at any visit during the study, the pulmonologist will conduct 
further examination, as per local standard practice, to rule out or confirm the diagnosis. 
3.3.11 Dermatologist 
A dermatologist will perform complete skin examination as scheduled in the study protocol 
[see Section 7.3.13].

dermatologist will conduct further examination, as per local standard practice, to rule out 
or confirm the diagnosis. 
3.4 Study committees  
3.4.1 Independent Data Monitoring Committee 
An Independent Data Monitoring Committee (IDMC) has overall responsibility for 
safeguarding the interests of subjects by reviewing unblinded safety and efficacy data 
obtained in the study and making appropriate recommendations based on the reported data, 
thus ensuring that the study is being conducted with the highest scientific and ethical 
standards. The IDMC is also responsible for reviewing the data generated and for 
recommending on subsequent actions to be taken. These actions may include: 
• Recommending modifications to the study protocol to enhance subject’s safety.  
• Recommending the termination of the study at any time if major concerns arise 
regarding the safety of ponesimod. 
The IDMC is composed of physicians with relevant medical expertise (including a 
neurologist, a neurovirologist, a neurologist with MRI expertise or a neuroradiologist, a 
cardiologist, a pulmonologist), and a statistician and will be fully operational prior to 
enrolment of the first subject into the study. The composition and operation of the IDMC 
are described in the IDMC charter. 
3.4.2 Statistical Analysis Center 
A Statistical Analysis Center (SAC), a Contract Research Organization (CRO) not 
otherwise involved in study conduct or statistical analysis, will generate all unblinded 
analysis reports, throughout the trial period, exclusively for review by the IDMC. The 
unblinded reports will be generated from blinded efficacy and safety data periodically 
transferred to the SAC.  
3.4.3 Ophthalmology Safety Board 
An Ophthalmology Safety Board (OSB) composed of two independent ophthalmologists 
will review and evaluate in a blinded fashion any new or suspected cases of macular edema. 
The composition and operation of the OSB are described in the OSB charter. 
3.4.4 Major adverse cardiovascular events adjudication board 
A major adverse cardiovascular events (MACE) adjudication board will review and 
evaluate in a blinded fashion the MACE reported in the study. The selection of AEs that 
will be sent for adjudication will be based on a pre-defined list of preferred terms belonging 
to relevant Standardized MedDRA Queries. For each AE sent for MACE adjudication, the

MACE adjudication board will determine whether the event belongs or not to one of the 
pre-specified categories including cardiovascular death, myocardial infarction, and stroke. 
The composition and operations of MACE adjudication board will be described in the 
MACE adjudication board charter.

SUBJECT POPULATION 
4.1 Subject population description 
This study will enroll adult male and female subjects aged 18 to 55 years with established 
diagnosis of MS, as defined by the 2010 revision of McDonald Diagnostic Criteria 
[Polman 2011], with relapsing course from onset (i.e., RRMS and SPMS with 
superimposed relapses). The trial will include up to 15% of subjects with SPMS with 
superimposed relapses, but no forced randomization is planned.  
Subjects must have active disease evidenced by one or more MS attacks within the period 
of 12 to 1 months prior to baseline EDSS assessment, or by two or more MS attacks within 
the 24 to 1 months prior to baseline EDSS assessment, or with one or more Gd+ lesion(s) 
of the brain on an MRI performed within 6 months prior to baseline EDSS assessment. The 
MRI assessed at Visit 2 (Baseline) may be serving as the qualifying scan. Enrolled subjects 
must be ambulatory with an EDSS score of up to 5.5 inclusive. The subjects may be 
treatment-naïve (i.e., no MS disease-modifying therapy received at any time in the past) or 
previously treated with IFN β-1a, IFN β-1b, glatiramer acetate, dimethyl fumarate, or 
natalizumab.  
Subjects with significant medical conditions or therapies for such conditions 
(e.g., cardiovascular, pulmonary, immunological, hepatic, ophthalmological) are not 
eligible to enter the study.  
Eligible subjects must be able and willing to give informed consent for participation in the 
clinical study. 
4.2 Rationale for the selection of the study population 
RMS is the most frequent presentation of MS. Despite multiple therapies available, many 
subjects continue to experience relapses and accumulate disability.  
Subjects with SPMS represent a significant unmet medical need for new therapeutic 
options. These subjects have generally been less studied and have often not been included 
in pivotal trials of medications approved for treatment of RMS. For these reasons, it is 
important to also evaluate the benefit/risk profile of ponesimod in subjects with SPMS with 
superimposed relapses.

The clinical relevance of McDonald 2010 Diagnostic Criteria, including subjects with only 
one attack, in the presence of supplementary clinical and/or MRI criteria as well as the 
value of early treatment in MS are widely recognized. 
The study will enroll subjects with recent evidence of active disease as determined by 
clinical or imaging criteria, as these are prognostic factors that identify a patient population 
in whom effective disease-modifying treatment is particularly indicated. 
The study will recruit adult subjects, restricted to subjects between 18 and 55 years of age, 
as non-MS-specific MRI lesions can appear more frequently in older age. Such lesions and 
other CNS changes due to aging make the assessment of MS more difficult and may affect 
the response to treatment, which could result in inconclusive trial results. The age range of 
the study population will be representative of the general RMS population.  
Subjects with an EDSS score 0−5.5 may have developed mild to moderate impairment but 
are still ambulatory. The clinical care and management of these subjects is compatible with 
their inclusion in clinical trials. Outcomes measured in this study require ambulatory 
subjects (e.g., MSFC). The subjects with EDSS above 5.5 will often have SPMS with 
declining disease activity and would therefore make the study population too 
heterogeneous for testing a disease-modifying potential of a new MS compound. 
Subjects with significant cardiovascular, pulmonary, immunological, hepatic, or 
ophthalmological 
medical 
conditions 
or 
therapies 
are 
excluded 
since 
such 
conditions/therapies have the potential to put the subject at increased risk of adverse drug 
reactions, and/or interfere with the treatment effect, study assessment and interpretation of 
study results.  
4.3 Inclusion criteria 
For inclusion in the study, all of the following inclusion criteria must be fulfilled. It is not 
permitted to waive any of the criteria for any subject:

4.5 Subjects of reproductive potential 
WOCBP and fertile male subjects participating in the study must agree that they will take 
means to reduce reproductive risk as defined in the following sections. 
4.5.1 Women of childbearing potential 
A woman is considered to be of childbearing potential unless she meets at least one of the 
following criteria: 
• 
Previous bilateral salpingo-oophorectomy or hysterectomy. 
• 
Premature ovarian failure confirmed by a specialist. 
• 
XY genotype, Turner syndrome, uterine agenesis.

it must be taken for at least 30 days prior to randomization. Non hormonal 
methods of contraception (e.g., intrauterine device) should be in place no later 
than Visit 2 (Baseline). 
− Group 2: Female or male condoms, diaphragm or cervical cap. 
OR 
• 
True abstinence from intercourse with a male partner only when this is in line with the 
preferred lifestyle of the subject. 
OR 
• 
Permanent female sterilization (tubal occlusion/ligation at least 6 weeks prior to 
Visit 1 [Screening]). 
OR 
• 
Sterilization of the male partner with documented post-vasectomy confirmation of the 
absence of sperm in the ejaculate. 
Rhythm methods or the use of a condom by a male partner alone are not considered 
acceptable methods of contraception for this study.  
The methods of contraception used (including non-pharmacological methods) must be 
recorded in the eCRF. At all visits and 4-weekly telephone calls the methods of 
contraception will be reviewed and the contraceptive method form entered in the eCRF 
must be updated as applicable. 
4.5.2 Fertile male subject 
A fertile male is defined as physiologically capable of conceiving an offspring. 
Since teriflunomide is detected in semen [Aubagio® USPI, Aubagio® SmPC], fertile male 
subjects participating in the study who are sexually active with WOCBP must agree to use 
a condom during the treatment period and for up to 6 weeks after the first of two tests 
showing teriflunomide plasma level < 0.02 mg/L and agree not to father a child during this 
period. The female partners of the fertile male subjects, if WOCBP, will need to use 
effective methods of contraception [Aubagio® USPI, Aubagio® SmPC], as assessed by the 
investigator during the same period. 
4.6 Medical history 
Relevant medical history, as defined below, must be recorded in the eCRF: 
• 
Significant chronic medical conditions at any time prior to the study (in the opinion of 
the investigator) 
• 
Cardiac, cardiovascular, pulmonary, liver, renal, eye disorder, and skin conditions, 
peripheral edema, serious infections leading to hospitalization, and malignant tumors

24 months prior to the study. The onset and resolution date, and treatment of these 
relapses (corticosteroids, ACTH, plasmapheresis etc.) will also be reported. 
• 
Number of documented Gd+ lesions per scan and number of documented 
T2 hyperintense lesions per scan on any MRI scan performed within 24 months prior 
to the study. Additionally, the condition of the MRI scan will be collected

maintenance period (Day 15 until EOT).  
During an initial phase of the study, the study drugs in the up-titration period will be 
administered in a double-dummy fashion. Ponesimod (or matching placebo) will be 
presented as tablet, and teriflunomide 14 mg (or matching placebo) will be presented as 
capsule (i.e., daily administration of one tablet and one capsule). At a later phase, the

double-dummy material (tablet and capsule) will be replaced by the daily administration 
of one capsule containing either ponesimod or teriflunomide.  
In the maintenance period, the study treatment consists of the daily administration of one 
capsule containing ponesimod 20 mg or teriflunomide 14 mg.  
If the subject expresses any concern regarding her/his ability to swallow the medicine, 
she/he will be shown an example of a capsule to be used in the study and will be given the 
option to perform a swallowing test with a placebo capsule at Visit 2 (Baseline) in order to 
test future compliance with study drug intake requirements. The test is to be done under 
the supervision of the site personnel. 
5.1.1 Investigational treatment: description and rationale 
Ponesimod is supplied as its free base, in oral film-coated tablets at the doses 
of 2, 3, 4, 5, 6, 7, 8, 9, 10, and 20 mg. The 20-mg tablet is over-encapsulated. During an 
initial phase of the study, one tablet of ponesimod 2, 3, 4, 5, 6, 7, 8, 9, or 10 mg (or matching 
placebo) will be taken orally o.d. during the up-titration period (Day 1 to 14). The matching 
placebos for the doses of 2, 3, 4, 5, 6, 7, 8, 9, and 10 mg are supplied as identical tablets, 
formulated with the same excipients but without the active ingredient, ponesimod. At a 
later phase, once the development of the over-encapsulated forms of the ponesimod tablets 
for the up-titration is completed, one capsule of 2, 3, 4, 5, 6, 7, 8, 9, and 10 mg ponesimod 
(or matching teriflunomide 14 mg) will be taken orally o.d. during the up-titration period. 
During the maintenance period, one capsule of ponesimod 20 mg (or matching 
teriflunomide 14 mg) will be taken orally o.d. 
Based on the available data and considering the currently available therapeutic options, 
ponesimod 20 mg displays the optimal benefit-risk balance for further development in 
RMS.  
Lower doses of ponesimod are unlikely to provide an adequate level of disease control and 
do not offer a relevantly improved safety profile. Consistent with a lower effect on 
lymphocytes, 10 mg ponesimod was unable to suppress MRI brain inflammatory activity 
to the level achieved with 20 mg and continued to show higher levels of clinical disease 
activity with more relapses and accumulation of disability after 3 years of treatment. While 
less efficacious, 10 mg showed similar rates of AEs and discontinuations when compared 
to 20 mg [see Sections 1.3.2.3 and 1.3.2.4].  
Doses higher than 20 mg were associated with decreased tolerability; there were increased 
discontinuation rates with 40 mg mainly due to higher pulmonary function effects and 
increased incidence of liver enzyme elevations. By contrast, there was a similar or small 
incremental effect of 40 mg compared to 20 mg on lymphocytes, MRI brain inflammatory 
activity, and clinical disease activity [see Sections 1.3.2.3 and 1.3.2.4].

5.1.2 Comparator and matching placebo: description and rationale 
Teriflunomide is supplied for this study as film-coated tablets as the commercially 
available Aubagio® tablets. Each tablet contains 14 mg of teriflunomide and excipients. 
Teriflunomide tablets are over-encapsulated. The study treatments of the up-titration 
period are administered in a double-dummy fashion, one capsule of teriflunomide or 
matching placebo will be taken orally o.d. during up-titration (Days 1 to 14). Matching 
placebo capsules will contain only a filling excipient.  
In the maintenance period, study treatment always consists of the daily oral administration 
of one capsule containing teriflunomide or ponesimod (i.e., no double-dummy). The dose 
and regimen of teriflunomide are in accordance with the product labeling of Aubagio® 
[Aubagio® USPI, Aubagio® SmPC]. Aubagio® is manufactured by Sanofi. 
Two dosage forms of Aubagio®, 7 mg and 14 mg, have been approved in US, while only 
14 mg has been approved in the EU and other countries such as Australia. The reduction 
in relapse rates observed in the Phase 3 studies were comparable between the two doses, 
but the 7 mg dose has failed to demonstrate an effect on accumulation of disability. 
Teriflunomide 14 mg appears to be an appropriate comparator for ponesimod 20 mg. 
Demonstration of superiority over teriflunomide 14 mg in terms of ARR is clinically 
relevant, as it would provide evidence of significant benefit of the new investigational drug 
compared to a world-wide approved, effective, first-line oral therapy that has been shown 
to reduce relapse rate and accumulation of disability. 
5.1.3 Study treatment administration 
5.1.3.1 Titration 
A gradual up-titration of ponesimod from a 2 mg starting dose to a 20 mg maintenance 
dose over a period of 14 days was found to successfully mitigate first-dose effects. This 
2-week up-titration regimen will be implemented in the study on initiation of treatment 
(Day 1) and on days of re-initiation of treatment following treatment interruption of more 
than 3 days [see Section 5.1.9].  
In order to keep the blind of the study, subjects randomized to teriflunomide will undergo 
a mock up-titration.

Study drug up-titration, other than described above, is prohibited. Study drug 
down-titration is not foreseen in any situation and is prohibited. 
One tablet and one capsule (during the double-dummy phase) or one capsule will be taken 
orally o.d., in the morning, either with breakfast or before or after breakfast, preferably at 
approximately the same time each day. The capsule and tablet will be swallowed as a 
whole. When applicable, the tablet and the capsule (during double-dummy phase) will be 
taken in the shortest time from each other with no predefined order (tablet or capsule can 
be taken first). The last administration date and time of study drug (tablets and capsules) 
prior to the study visits and the administration date and time of study drug (tablets and 
capsules) on the days of visits will be recorded in the eCRF.  
5.1.3.2 Maintenance 
One capsule of ponesimod or teriflunomide will be taken orally o.d., preferably in the 
morning, either with breakfast or before or after breakfast. It is preferable that the capsule 
be taken each day at approximately the same time. The capsule will be swallowed as a 
whole. The last administration date and time of study drug (capsule) prior to the study visits 
and the administration date and time of study drug (capsule) on the days of visits will be 
recorded in the eCRF. 
On the day of the study visits, study drug must be administered only after the completion 
of the pre-dose safety assessments (diastolic blood pressure [DBP], systolic blood pressure 
[SBP], ECGs, PFTs, laboratory tests) and PK sampling (if scheduled).

5.1.4 Treatment assignment 
A total of 1100 eligible subjects will be randomized in a 1:1 ratio to ponesimod 20 mg or 
teriflunomide 14 mg, stratified by prior use of MS disease-modifying treatment in the last 
two years prior to randomization (yes, no) and by baseline EDSS score (EDSS ≤ 3.5, EDSS 
> 3.5). 
Each of the study sites will be assigned a unique site number, and every subject will receive 
a unique screening number (= subject number), which identifies the subject throughout the 
study. After having confirmed the eligibility of the subject and prior to the start of study 
treatment, the investigator/delegate contacts the interactive response technology (IRT) at 
Visit 3 to randomize the subject. The IRT assigns a randomization number to the subject 
and assigns the treatment kit number, which matches the treatment arm assigned by the 
randomization list to the randomization number of each subject. 
The randomization list is generated by an independent CRO (ALMAC Clinical 
technologies−see contact details in the IRT manual) and kept strictly confidential. 
5.1.5 Blinding 
5.1.5.1 Study drug material related blinding 
This study will be performed in a double-blind fashion. The investigator and study staff, 
the subjects, the monitors, all Clinical Trial Team (CTT) members at Actelion and CROs 
involved in the conduct of the study will remain blinded to the treatment until study closure. 
Actelion staff responsible for clinical trial supply distribution will need to be unblinded to 
ensure adequate study oversight. These persons will be clearly identified, their unblinding 
will be documented in the trial master file and they will not take part in any CTT meeting 
after study set-up has been completed.  
Until the time of unblinding for final data analysis, the randomization list is kept strictly 
confidential and accessible only to authorized persons who are not involved in the conduct 
of the study.  
The investigational treatment and active comparator, and their respective matching 
placebos (if applicable, during the initial stage when the up-titration study drug treatments 
are administered in a double-dummy fashion) are indistinguishable, and all subject’s kits 
will be packaged in the same way. 
5.1.5.2 Functional blinding 
First-dose effects on HR and AV conduction, lymphocyte counts reduction, and 
teriflunomide plasma concentration have been identified as potentially unblinding 
information. Access to this information by the site’s staff and sponsor’s study team will be 
restricted. The following measures will be taken to ensure that the efficacy assessments

(i.e., EDSS/FS) are done independently and that cardiac safety assessments, lymphocyte 
count and teriflunomide plasma concentration assessment are performed and reviewed 
without potential to introduce a bias: 
• The primary endpoint (ARR) and the second key secondary endpoint (disability 
accumulation) are based on the evaluations of the EDSS and FSs, assessed by an 
efficacy assessor, not involved in any other aspects of patient care and management 
throughout the study. 
• The subject will be instructed not to discuss AEs (other than those required for EDSS 
assessments), HR, pulmonary function and/or concomitant medications with the 
efficacy assessor.  
• The principal investigator / treating neurologist and first-dose administrator evaluating 
cardiac safety assessments must not discuss any issues related to patient care and 
management unless mandated for reasons of subject safety. On Day 1 and on the first 
day of re-initiation of study drug when post-dose monitoring is required, significant 
findings, which in view of the first-dose administrator meet the definition of an AE, 
have an onset after the study drug intake, and are resolved at the time of discharge of 
the subject, must be recorded directly on the AE page of the eCRF by the first-dose 
administrator/delegate. These AEs, the ECG interpretation reports and BP data 
collected on these days will not be visible to any of the blinded study personnel at the 
study site. At the sponsor’s level, these events and ECGs and BP data will be entered 
into a separate eCRF and will only be visible to the site monitor and to the first-dose 
monitor. The site monitor will not reveal any potentially unblinding information to the 
rest of the site team or to the sponsor study team and will only discuss any of these data 
with the first-dose administrator or the first-dose monitor. The first-dose monitor is a 
role created by the sponsor for the purpose of keeping the rest of the sponsor’s team 
blinded and assigned to (a) specific individual(s). The first-dose monitor will not reveal 
any potentially unblinding information to the site team or to the rest of the sponsor 
study team and her/his access to potentially unblinding information will be documented 
in the trial master file. 
• Results of the total WBC count and total lymphocyte count will not be communicated 
to the sites, sponsor, and CRO unless one of the below applies: 
− A total lymphocyte count < 0.2 × 109/L is recorded by the central laboratory. In 
this event, an alert containing the total lymphocyte count result will be sent to 
the principal investigator and the sponsor. FU monitoring must be provided as 
described in Sections 5.1.13 and 7.3.14.

− A WBC count > 20 × 109/L or a lymphocyte count > 8.0 × 109/L is recorded by 
the central laboratory [see Appendix 6]. In this event, an alert containing the 
total WBC or lymphocyte count result (as applicable) will be sent to the 
principal investigator and the sponsor.  
− WBC and total lymphocyte counts measured at Visit 1 (Screening), 
2 (Baseline), and any of the visits in the PTOP (if applicable) will be visible to 
the treating neurologist. Upon discontinuation of ponesimod, lymphocytes 
counts return to within normal ranges within one week. Lymphocytes counts 
are therefore expected to have returned to normal range during the 30 days 
safety follow up period preceding the start of PTOP. 
• Teriflunomide plasma concentration will be assessed after study treatment 
discontinuation for women of childbearing potential and fertile male subjects not 
entering the extension study and willing to discontinue contraception [see Section 4.5]. 
Teriflunomide plasma concentration can also be assessed for any subjects not entering 
the extension study if deemed necessary for the subject’s safety, at the investigator’s 
discretion. The following rules will apply: 
− For subjects entering the AC-058B303 extension study, no teriflunomide 
plasma testing will be conducted as part of the AC-058B301 study. The timing 
of teriflunomide plasma concentration testing and procedures are described in 
the AC-058B303 study protocol (separate protocol). 
− For subjects not entering the AC-058B303 extension study, teriflunomide 
plasma concentration testing should not occur before: 
o 20 weeks after last drug intake, if the subject’s compliance with the 
accelerated elimination procedure has been assessed as sufficient 
[see Section 5.1.14.2]. 
o 35 weeks (i.e., 8 months) after last drug intake or EOS, whichever is 
last, if the subject’s compliance with the accelerated elimination 
procedure has not been assessed as sufficient [see Sections 5.1.14.1 and 
5.1.14.4]. 
− In all cases, the results will not be communicated to the sponsor (except site 
monitor). Sites will receive the following notifications: 
o if plasma concentration was < 0.02 mg/L: notification that the 
teriflunomide test was successfully performed

o if plasma concentration was ≥ 0.02 mg/L: full test results and 
notification that the subject should either repeat the accelerated 
elimination procedure [see Section 5.1.14] or wait an additional time 
period before another test may be performed. 
• All MRI scans collected for the assessment of efficacy endpoints are evaluated by a 
central lab (MIAC) also in a fully blinded fashion. 
Under no circumstances should potentially unblinding information be shared with the 
efficacy assessor. 
5.1.6 Unblinding 
5.1.6.1 Unblinding for final analyses 
Full randomization information will be made available for data analysis only after database 
closure in accordance with Actelion standard operating procedures (SOPs). 
5.1.6.2 Unblinding for IDMC 
A SAC, not otherwise involved in the design, conduct and analysis of the study, will have 
access to the randomization code in order to prepare unblinded reports for review by the 
IDMC (for IDMC review meetings during the course of the trial). The randomization code 
will be made available to the SAC in accordance with the sponsor’s SOPs. 
5.1.6.3 Unblinding for suspected unexpected serious adverse reactions 
When a suspected unexpected serious adverse reaction (SUSAR) occurs for a subject 
participating in the study, Actelion Global Drug Safety will request the unblinding of the 
treatment assignment. The randomization code will not be communicated to the site staff 
or to the Actelion study team; unblinded SUSAR information will be anonymized and 
provided to Actelion Global Drug Safety, respective health authorities and Institutional 
Review Boards (IRBs) / Independent Ethics Committees (IECs) only. SUSARs will be 
reported to investigators in a blinded fashion. 
5.1.6.4 Emergency procedure for unblinding 
The investigator, study staff and sponsor staff must remain blinded to the subject’s 
treatment assignment. The identity of the study treatment may be revealed only if the 
subject experiences a medical event, the management of which would require knowledge 
of the blinded treatment assignment. In this case, the investigator can receive the unblinded 
randomization code for study treatment allocation through the IRT. In these situations, the 
decision to unblind resides solely with the investigator. Whenever it is possible and if it 
does not interfere with (or does not delay) any decision in the best interest of the subject, 
the investigator is invited to discuss the intended code break with Actelion.

The occurrence of any code break during the study must be clearly justified and explained 
by the investigator. The investigator must not disclose the unblinded treatment in the eCRF 
or to the sponsor or its delegates. In all cases, Actelion must be informed as soon as possible 
before or after the code break. 
The circumstances leading to the code break must be documented in the site study file and 
eCRF. 
Refer to the IRT guidelines for complete information regarding the IRT procedures for 
randomization, study drug assignment, and unblinding. 
5.1.7 Study treatment supply 
Manufacture, labeling, packaging and supply of study treatments will be conducted 
according to Good Manufacturing Practice, Good Clinical Practice (GCP) and any local or 
national regulatory requirements. 
All treatment supplies are to be used only in accordance with this protocol and not for any 
other purpose. 
5.1.7.1 Study treatment packaging and labeling 
5.1.7.1.1 Study treatment packaging 
Study treatment is provided as capsules and tablets and supplied in childproof blister packs. 
5.1.7.1.2 Study treatment labeling 
Study treatment is labeled to comply with the applicable laws and regulations of the 
countries in which the study sites are located.  
5.1.7.2 Study treatment distribution and storage  
Treatment supplies must be kept in an appropriate, secure area and stored according to the 
conditions specified on the medication labels. The study drug must be stored below 25 °C. 
The study drug must not be refrigerated.  
5.1.7.3 Study treatment dispensing 
The subjects will receive sufficient study treatment to cover the period up to the next 
scheduled visit. Alternatively, scheduled study medication dispensing/return procedures 
may be adapted according to the site practice (i.e., if the subject comes to the investigational 
site more frequently than the scheduled visits, it is then possible to dispense medication in 
smaller quantity). Subjects are asked to return all used, partially used and unused study 
treatment blister packs at each visit. If the subject forgets to bring the remaining study 
treatment to a study visit, she/he must be instructed not to take any tablet/capsules from the 
remaining study treatment and to bring it at the next visit.

An accurate record of the date and amount of study treatment dispensed to each subject 
must be available for inspection at any time.  
5.1.7.4 Study treatment return and destruction  
On an ongoing basis and/or on termination of the study, the monitor will collect used and 
unused subject kits, which will be sent to the warehouse, where Actelion or a deputy will 
check treatment reconciliation. 
5.1.8 Drug accountability and compliance 
5.1.8.1 Drug accountability 
Records of study drug dispensed and returned, dosages administered, and intervals between 
visits are kept during the study. Study treatment accountability must be performed by the 
study staff on the day of the visit and before providing further study treatment, in order to 
ensure that the subject is compliant with study requirements. Study treatment 
accountability is checked by the monitor during site visits and at EOS.  
5.1.8.2 Drug compliance 
Subjects’ compliance with study drug intake will be recorded using an electronic diary. On 
each day, the subjects will be asked to enter the date, time, number of capsules (and tablets, 
if applicable) taken, and the unique blister-card identifying number from which the 
capsules (and tablets, if applicable) are (were) taken from. In addition, during the 
up-titration, the position of the well on the blister card will be recorded in order to check 
that capsules and tablets (if applicable) were taken in the correct sequence [see gradual up-
titration in Section 5.1.3.1].  
The electronic diary will give feed-back and instruct the subject to contact the investigator 
as soon as possible before taking next dose, whenever one of the following is observed: 
• Dose is taken in an incorrect sequence during the up-titration (e.g., capsule at position 
6 taken before capsule at position 4 on the blister card);  
• 1 or more dose(s) (capsule and/or tablet if applicable) are missed during the up-titration; 
• 4 or more doses are missed during the maintenance.  
Additionally, feedback will be given to the subject whenever 1 to 3 dose(s) are missed 
during the maintenance. 
At each visit, the site personnel will crosscheck the subject’s compliance as indicated in 
the electronic diary against the study drug accountability [see Section 5.1.8.1]. Subjects 
will be asked to explain the observed discrepancies. Interruptions with known dates will 
be recorded accordingly in the study drug log [see Section 5.1.9]. Study drug intake 
requirements will be re-explained to the subject each time an interruption is observed.

5.1.9 Study treatment dose adjustments and interruptions 
Study drug up-titration, other than described in Section 5.1.3, is prohibited. Study drug 
down-titration is not foreseen in any situation and is prohibited. 
Study drug interruption should be avoided. If study treatment intake is interrupted by the 
subject for any reason, she/he must immediately inform the investigator/treating 
neurologist. 
Study treatment may be temporarily interrupted in response to an AE, a diagnostic or 
therapeutic procedure, a laboratory abnormality, or for administrative reasons. 
Study-specific criteria for interruption of study treatment are described in Section 5.1.13. 
The duration of an interruption is determined by the investigator and is not limited in time. 
At maximum, it will last until the investigator deems the subject necessary to require 
another MS treatment. In this event, it is recommended performing an accelerated 
elimination procedure [see Section 5.1.14] before a new immunomodulatory treatment for 
MS is started.  
Detailed guidance on how to re-initiate study drug in the event of drug interruption is 
provided in Section 5.1.10. 
Study treatment dose adjustments/interruptions must be recorded in the eCRF. 
5.1.10 Guidance for re-initiation of study treatment in the event of study treatment 
interruption 
If study drug intake is interrupted by the subject for any reason, she/he must immediately 
inform the principal investigator / treating neurologist. 
The following guidance is provided for re-initiation of investigational study drug after 
study drug interruptions. 
A schematic overview of the re-initiation algorithm is given below in Figure 5.  
Depending on the day, time, and duration of study drug interruption, the following 
procedures will be followed. 
• If the subject missed taking the dose in the morning: 
− The dose should be taken at any time on the same day. 
− Regular dosing should be continued with the morning dose on the following day. 
• If the subject missed taking the dose for one or more days during treatment up-titration 
(from 1 to 14 days after the first-dose of initiation/re-initiation of the study drug):

− The original up-titration scheme needs to be re-applied, with the initial dose and 
gradual up-titration steps for 14 days after the first-dose of re-initiation of the study 
drug. 
− On the day of the re-initiation of investigational study drug, the subject must be 
monitored for at least 4 h post-dose by the first-dose administrator, following the 
cardiac assessment schedule and applying the discharge criteria as described for 
Day 1 [see Section 5.1.11]. 
• If the subject missed taking the dose for up to three consecutive days during treatment 
maintenance (from 14 days after the first dose of initiation/re-initiation of the study 
drug onwards): 
− Dosing should be continued in the morning following the last day without 
investigational study drug intake, with the same dose taken prior to study drug 
interruption. 
− Study drug intake may be re-initiated by the subject at home. 
− Subjects must be instructed to contact the investigator immediately if they 
experience any symptoms of bradycardia (e.g., dizziness, vertigo, syncope). 
• If the subject missed taking the dose for four or more consecutive days during treatment 
maintenance (from 14 days after the first dose of initiation/re-initiation of the study 
drug onwards):  
− The original up-titration scheme for the investigational study drug needs to be 
re-applied. 
− On the day of the re-initiation of treatment, the subject must be monitored for at 
least 4 h post-dose by the first-dose administrator, following the cardiac assessment 
schedule and applying the discharge criteria as described for Day 1 [see Section 
5.1.11]. 
Whenever the investigator / treating neurologist becomes aware that the subject did not 
report having missed the study drug intake for one or more days during up-titration or four 
or more days during maintenance and has continued dosing, the subject should be 
interviewed by the investigator / treating neurologist for any symptoms related to 
bradycardia and further examinations (e.g., 12-lead ECG, BP measurement) may be 
performed at the discretion of the investigator / treating neurologist. Based on an 
assessment of the clinical findings and the likelihood of subject’s adherence to treatment, 
the investigator / treating neurologist will determine whether the subject can continue 
regular dosing, need to re-initiate treatment, or should permanently discontinue treatment.

5.1.11 Criteria for discharge from cardiac monitoring on Day 1, and on the first day 
of re-initiation of the investigational study drug following treatment 
interruptions 
At the time of discharge from cardiac monitoring (i.e., when the evaluation of the pre-dose 
and all the hourly post-dose ECGs until 4 h post-dose have been obtained) on Day 1, and 
on the first day of re-initiation of study drug following drug interruptions, the following 
criteria must be met: 
• ECG-derived resting HR > 45 bpm, and if HR < 50 bpm it must not be the lowest value 
post-dose; 
• SBP > 90 mmHg; 
• QTcF < 500 ms and QTcF increase from pre-dose < 60ms;

• No persisting significant ECG abnormality (e.g., AV block second- or third-degree) or 
ongoing AE requiring continued cardiac monitoring or prohibiting study continuation 
as an out-patient. 
If the subject does not meet the discharge criteria (as described above) at 4 h post-dose, the 
subject should be carefully monitored for an additional period, and a 12-lead ECG and a 
BP measurement must be performed every hour. The subject can be discharged from 
cardiac monitoring as soon as the above criteria are met. 
Should the subject not meet the criteria for discharge from cardiac monitoring at 12 h post-
dose, she/he must be permanently discontinued from study drug. Subjects who are 
permanently discontinued should not be discharged from cardiac monitoring before vital 
signs return to near baseline values or until there is no persisting ECG abnormality 
(e.g., AV block second degree or higher), ongoing AE requiring continued cardiac 
monitoring, or until medically indicated. 
5.1.12 Premature discontinuation of study treatment 
In the study, the premature discontinuation of study treatment is defined as a permanent 
discontinuation of study treatment earlier than the planned treatment duration of 
108 weeks. The decision to prematurely discontinue study treatment may be made by the 
subject, the investigator or Actelion. 
A subject has the right to prematurely discontinue study treatment at any time by 
withdrawal from treatment only or by withdrawal from treatment and any further 
participation in the study. 
The investigator should discontinue study treatment for a given subject if, on balance, 
she/he believes that continued administration would be contrary to the best interests of the 
subject. In case of clinically significant progression of the disease as judged by the 
investigator, the investigator should consider switching to another potentially more 
effective therapy, discuss alternative treatment options with the subject, and document the 
outcome of this discussion in the medical records. 
Premature discontinuation of study treatment may also result from a decision by Actelion, 
e.g., in case of premature termination or suspension of the study [see Section 9.3]. 
The main reason and whether discontinuation of study treatment is the decision of the 
subject, the investigator, or Actelion must be documented in the eCRF. 
A subject who prematurely discontinues study treatment is NOT considered as withdrawn 
from the study and will be followed up until Week 108 in the PTOP or until the end of the 
safety FU period (30 days after study drug discontinuation), whichever comes last [see

Section 3.1.3], provided that the subject’s consent for this limited participation in the study 
has not been withdrawn. 
A subject who prematurely discontinues study treatment and withdraws consent to 
participate in any further study assessments is considered withdrawn from the study. 
Subjects who die or are lost to FU are also considered as withdrawn from the study. 
Withdrawal from the study and FU medical care of subjects withdrawn from the study is 
described in Sections 9.2 and 9.4, respectively. 
In the event of permanent discontinuation from study drug due to any reason, the 
investigator should consider prescribing appropriate treatment for MS according to the 
local clinical practice and availability. The investigator should exercise caution when 
considering the switch to another immunomodulatory MS treatment. Initiation of 
immunomodulatory therapies is best avoided during the FU period of 15 days and until an 
accelerated elimination procedure for teriflunomide has been conducted to minimize the 
risk of immunosuppression.  
5.1.13 Study-specific criteria for interruption / premature discontinuation of study 
treatment and management of clinically relevant events 
An accelerated elimination procedure must be used by all subjects permanently 
discontinued, after the last dose of study drug [see Section 5.1.14]. 
5.1.13.1 Cardiovascular 
Subjects must be permanently discontinued from study drug if: 
• The following change in HR is observed at any time throughout the study, as 
documented by 12-lead ECG: 
− HR < 30 bpm, or 
− HR < 40 bpm is sustained for at least 1 h and is associated with symptoms of 
bradycardia (e.g., syncope, dizziness, or vertigo), or 
• QTcF > 500 ms is observed at any time throughout the study, as documented by 12-lead 
ECG, or 
• The subject does not meet the criteria for discharge from cardiac monitoring on Day 1, 
or on the first day of re-initiation of study drug following drug interruptions after 12 h 
post-dose monitoring, or 
• The subject needs to receive systemic chronic treatment with β-blockers, diltiazem, 
verapamil, digoxin, or any other anti-arrhythmic or HR lowering therapy 
[non-exhaustive list of drugs provided in Appendix 4].

FU monitoring will have to be provided until the event resolves, the condition is stable, or 
the change is regarded as no longer clinically relevant. 
Continuous ECG monitoring is recommended for subjects who meet study drug 
discontinuation criteria related to bradycardia or other arrhythmia. Subjects who are 
permanently discontinued should not be discharged from the monitored setting before vital 
signs return to near baseline values and until there is no persisting ECG abnormality (e.g., 
QT prolongation, AV block second degree or higher) or ongoing AE requiring (continued) 
cardiac monitoring, or until medically indicated. Any clinically relevant finding meeting 
the definition of an AE will be recorded accordingly in the respective eCRF. 
In case of any signs and symptoms of bradycardia or other arrhythmia (e.g., syncope, 
palpitations, etc.), at any time during the study treatment, the first-dose administrator 
and/or a cardiologist may be consulted. In case a cardiac origin is suspected, permanent 
discontinuation of study drug should be considered. 
In case subjects experience sustained de novo or worsening of pre-existing hypertension 
during the course of the treatment with the study drug which, in the opinion of the 
investigator, cannot be adequately controlled by medications, study drug should be 
permanently discontinued. 
5.1.13.2 Hematological abnormalities and infections 
Subjects must be permanently discontinued from study drug at any time throughout the 
study in the event of: 
• Confirmed neutrophil count < 1.0 × 109/L (< 1000 cells/mm3)  
• Confirmed platelet count < 50 × 109/L (< 50 000 cells/mm3) 
• Confirmed total lymphocyte count < 0.2 × 109/L (< 200 cells/mm3) 
Confirmation will be done as follows: 
Whenever a neutrophil count < 1.0 × 109/L, a platelet count < 50 × 109/L, or a total 
lymphocyte count < 0.2 × 109/L, is recorded by the central laboratory, an alert will be sent 
to the principal investigator and the sponsor. The principal investigator will immediately 
contact the subject and ask her/him to return to the site within 48 h at the latest to repeat 
the test at trough level (pre-dose) by the central laboratory (unless the clinical situation 
mandates immediate local testing). If the repeat test confirms a neutrophil count  
< 1.0 × 109/L, a platelet count < 50 × 109/L, or a total lymphocyte count < 0.2 × 109/L the 
study drug must be discontinued. Neutrophil, platelet, or lymphocyte counts must be 
monitored at least once a week by the central laboratory until the neutrophils or platelets 
have returned to ≥ 80% of the baseline value or the lymphocyte count has returned to

≥ 0.8 × 109/L or ≥ 80% of the baseline value. Any clinically relevant finding meeting the 
definition of an AE will be recorded accordingly in the eCRF. 
In the event of a decrease of neutrophil or platelet not reaching the above alert levels, test 
at trough level (pre-dose) may be repeated. Upon confirmation of the decline over time of 
neutrophil or platelet counts, study drug may be interrupted at the discretion of the 
investigator. Possible causes for this decline including signs and symptoms suggestive of 
an infection should be assessed.  
In the event of a suspected opportunistic infection of the CNS, the study drug must be 
interrupted and the subject referred to an expert in infectious diseases for further 
examination and treatment. For any other infection the subject should be treated as 
clinically indicated and study drug may be interrupted or permanently discontinued at the 
discretion of the investigator. In case of study drug interruption the subject will be closely 
observed and if the infection is resolved or not confirmed and the benefit/risk balance is 
considered acceptable for the subject to resume study treatment, the study drug may be re-
initiated at the discretion of the investigator. 
In the event of permanent discontinuation from study drug due to infection, adequate 
treatment needs to be provided and the subject must be monitored until complete resolution 
of the infection.  
A guidance for screening and monitoring of subjects for opportunistic infection is provided 
in Sections 5.1.13.2.1 and 5.1.13.2.2. Subjects must be advised to be proactive and alert in 
reporting any unusual neurological symptom and any signs and symptoms indicative of 
systemic infections, such as fever, malaise and fatigue. 
In the event of a suspected opportunistic infection in the CNS, unscheduled brain MRI 
scans may be performed at the investigator’s request.  
5.1.13.2.1 Guidance for screening, exclusion and on-treatment monitoring of subjects for 
progressive multifocal leukoencephalopathy 
Progressive multifocal leukoencephalopathy (PML) is an opportunistic infection of the 
CNS that can lead to death or severe disability. Active replication of the human polyoma 
John Cunningham Virus (JCV) in glial cells of the brain, causing lytic death in 
oligodendrocytes, is the underlying pathobiology of PML. The infection typically arises in 
severely immunocompromised subjects e.g., those with HIV infection, malignant disease, 
or transplanted organs. Development of PML is extremely rare in immunocompetent 
individuals. People with autoimmune rheumatic diseases, especially systemic lupus 
erythematosus, are also at higher risk of PML [Kappos 2011]. 
MS subjects treated with natalizumab are at increased risk of developing PML. In addition 
to natalizumab, cases of PML have been reported in subjects treated with various drugs,

usually in combination with corticosteroids, including alkylating agents (e.g., 
cyclophosphamide, carmustine, and dacarbazine), purine analogues (e.g., fludarabine, 
cladribine, and azathioprine), immunosuppressants (e.g., cyclosporine, tacrolimus, 
sirolimus, and mycophenolate), and therapeutic monoclonal antibodies (e.g., rituximab, 
infliximab, etanercept, basiliximab, daclizumab, efalizumab, alemtuzumab, and 
muromonab-CD3) [Kappos 2011]. 
Clinical features indicative of PML are: 
• Subacute onset 
• Occurs over several weeks and is progressive 
• Clinical presentation includes aphasia, behavioral and neurophysiological alteration, 
retrochiasmal visual deficits, hemiparesis, and seizures. 
In order to facilitate the recognition of potential PML infection in MS subjects and to 
minimize the risk of enrolling subjects with undiagnosed or unrecognized PML infection 
in the clinical study of ponesimod, the following guidance is provided. The proposed 
algorithm is based on the updated experts’ panel recommendation for monitoring subjects 
who receive treatment with natalizumab [Kappos 2011].  
Subjects with known PML infection or evidence of new neurological symptoms or MRI 
signs within 6 months prior to randomization that are compatible with a diagnosis of PML 
infection are not be eligible for the study. The proposed algorithm should be applied for all 
subjects with evidence of new neurological symptoms or MRI signs compatible with PML 
within 6 months prior to randomization [Figure 6].

For subjects who have been enrolled in the study and who, under the study treatment, 
present new neurological symptoms suggestive of pathology other than MS, the 
investigator should consider PML or another opportunistic infection of the CNS (especially 
in case of prior exposure to natalizumab or other immunosuppressive agents) and, in case 
of clinical features indicative of these conditions, the following diagnostic procedures are 
recommended: 
• Perform MRI including T1 sequences with Gd (and additional MRI sequences if 
needed) and include comparison with the previous MRI images in the interpretation of 
the MRI results; 
• Interrupt study drug until PML or other opportunistic CNS infection has been excluded 
with confidence; 
• Perform lumbar puncture and send cerebrospinal fluid (CSF) for JCV DNA testing by 
polymerase chain reaction (PCR) with an ultrasensitive assay. The JCV DNA assay 
should be based on quantitative real-time PCR to maximize sensitivity and specificity 
for detection, and an assay with a maximum lower limit of quantification of 50 DNA 
copies per mL should be used. 
Detection of JCV DNA in the CSF of a symptomatic subject confirms the diagnosis. 
However, a negative JCV PCR result should not exclude a possible diagnosis of PML. 
In case the CSF is negative but clinical signs and symptoms and/or MRI are still suggestive 
of PML: 
• Consider repeating CSF analysis; 
• Consider other opportunistic infections with CNS manifestations;  
• Manage the subject on suspicion of PML or other opportunistic CNS infections 
according to local guidelines. 
If,  
• There are no suspicious signs of PML or other opportunistic infections on MRI and 
• Lumbar puncture, if done, is negative for JC DNA, and 
• The neurological signs and symptoms show improvement and are no longer suspicious 
of PML and can be explained by MS or an alternative, not-infectious etiology, 
the suspicion of PML is not supported. Other causes of the atypical neurological signs or 
symptoms or MRI findings need to be considered. Re-starting of the study drug should be 
considered if the benefit/risk is still favorable, according to the investigator. 
However, if the investigator is still NOT able to rule out PML or another CNS opportunistic 
infection, the study drug should be permanently discontinued, the case should be reported

to the sponsor as an SAE and the subject should be managed according to the local standard 
of care. 
In case the MRI at scheduled visit shows signs atypical for MS, PML or other opportunistic 
infection should be considered based on the clinical signs and symptoms, MRI results, 
previous exposure to natalizumab or immunosuppressants, and laboratory tests including 
CSF analysis, if indicated. As long as there is suspicion of PML or other opportunistic 
infection, the study drug should be interrupted and should not be re-introduced until this 
suspicion has been ruled out. 
5.1.13.2.2 General guidance for monitoring of subjects for opportunistic infections other 
than PML during treatment 
Heightened vigilance is required for opportunistic infections, with particular attention to 
be paid to viral infections. However, investigators and physicians following subjects should 
also be alert to potential systemic infections caused by fungi and bacteria. In the event of 
an opportunistic infection, the subject must be referred to an expert in infectious diseases 
for further examination and treatment. The study drug must be permanently discontinued 
in case of opportunistic CNS infections. For any other opportunistic infections, the study 
drug may be interrupted or permanently discontinued at the discretion of the investigator. 
It is important to recognize that opportunistic infections caused by the reactivation of 
human herpes viruses (herpes simplex viruses, varicella-zoster virus, Epstein-Barr virus, 
cytomegalovirus) may be associated with neurological symptoms primarily. The 
neurotropic herpes viruses (herpes simplex and varicella-zoster) are frequent human 
pathogens and their reactivation can cause serious infections of the CNS such as 
encephalitis and meningitis. The most frequent characteristics of these infections are an 
acute onset, associated with fever, headache, confusion, personality changes, and 
disorientation. Any suspicion of these infections must lead to immediate discontinuation 
of study drug treatment and to early initiation of antiviral treatment [Steiner 2007]. 
Particular vigilance is required for rare and unusual neurological symptoms, as their 
recognition is crucial for the early diagnosis of neurotropic herpes viruses infections.  
The thorough physical examination and blood tests on the routine visits should be focused 
on any potential sign of skin, mucosal surfaces, gastrointestinal tract, liver, hematological 
etc, abnormality and organ dysfunction suggesting a potential opportunistic infection.  
Subjects should be advised to be proactive and alert in reporting any unusual neurological 
symptoms and any signs and symptoms indicative of systemic infections, such as fever, 
malaise and fatigue [Kappos 2007].

5.1.13.3 Respiratory system 
In case of abnormal spirometry results or persistent respiratory symptoms (e.g., dyspnea), 
the subject will be closely observed, spirometry will be repeated, and study drug 
discontinuation should be considered, according to the guidance provided in Table 5.

Resume regular PFTs schedule.  
AE = adverse event; FEV1 = forced expiratory volume in 1 second; FU = follow-up; FVC = forced vital vapacity;  
PFT = pulmonary function test. 
If clinically significant, persistent respiratory AEs (e.g., dyspnea) are reported, PFTs must 
be performed and study drug may be interrupted at the discretion of the investigator. In 
case of study drug interruption, the subject will be closely observed, FU PFTs will be 
performed, and further diagnostic work-up and consultation with a pulmonologist or other 
specialist should be considered according to local practice and the clinical situation. 
Following study drug interruption, if PFTs normalize and lung toxicity is unlikely, study 
drug may be re-initiated at the discretion of the investigator. 
The decision to permanently discontinue study drug will be made after evaluation of all 
available information concerning concomitant medications, other potential causes of 
respiratory AEs, and the clinical status of the subject. Further diagnostic work-up and

consultation with a pulmonologist or other specialist should be considered according to 
local practice and the clinical situation. 
Subjects experiencing respiratory symptoms and/or reduced pulmonary function during the 
course of the treatment with the study drug may be prescribed short-acting β2 agonist (to 
be used on ‘as needed’ basis / ‘PRN’ use), at the investigator’s discretion. If a subject fails 
to show symptom relief and/or reversibility, additional diagnostic work-up (e.g., high-
resolution computerized tomography, DLCO) and/or permanent study drug discontinuation 
should be considered at the discretion of the investigator. 
In all cases of permanent discontinuation, FU monitoring must be provided until respiratory 
AEs have resolved and changes in pulmonary function are no longer regarded as clinically 
relevant, or until medically indicated. 
5.1.13.4 Pregnancy 
If a subject becomes pregnant while on study drug, study drug must be permanently 
discontinued. The investigator must counsel the subject and discuss the risks of continuing 
with the pregnancy and the possible effects on the fetus. If the subject wishes to continue 
pregnancy, Actelion Global Drug Safety will request the unblinding of the treatment 
assignment and only the subject allocated to teriflunomide will perform an accelerated 
elimination procedure [see Section 5.1.14].  
If a female partner to a male study participant becomes pregnant while the study participant 
is on study drug, the study drug in the male subject must be permanently discontinued. 
Actelion Global Drug Safety will request the unblinding of the treatment assignment. In 
case the male subject has been on teriflunomide, the investigator must counsel the subject 
and discuss the risks of continuing with the pregnancy and the possible effects on the fetus. 
If the subject was on ponesimod, there is no risk for the female partner to continue 
pregnancy. The accelerated elimination procedure will be performed in the male subject 
only if the subject was on teriflunomide. 
Male and female subjects participating in the study and wishing to father a child or wishing 
to become pregnant during the study must discontinue study drug, perform an accelerated 
elimination procedure, and continue contraception as indicated per protocol until 6 weeks 
after the first of two tests indicating serum teriflunomide level < 0.02 mg/L. 
5.1.13.5 Liver abnormalities 
In case of abnormal liver tests or signs and symptoms suggestive of drug induced liver 
injury (DILI), the subject will be closely observed, liver tests will be repeated, and study 
drug discontinuation should be considered according to the guidance provided in Table 6.

return to the site as soon as possible after the time of receipt of the alert to repeat the liver 
enzyme and bilirubin tests by the central laboratory (unless the clinical situation mandates 
immediate local testing) according to the scheme illustrated in Table 6. Further diagnostic 
work-up and consultation with a hepatologist or other specialist should be considered, and 
adequate medical management should be provided according to local practice and the 
clinical situation. Any clinically relevant finding meeting the definition of an AE will be 
recorded accordingly in the eCRF. 
In case of study drug interruption, the subject will be closely observed and FU liver tests 
will be performed. Following study drug interruption, if liver tests normalize and 
drug-related hepatotoxicity is unlikely, study drug may be re-initiated at the discretion of 
the investigator. Re-initiation following interruption according to the above criteria can 
only be done once during the study. The decision to permanently discontinue study drug 
will be made after evaluation of all available information concerning concomitant 
medications, other potential causes of hepatotoxicity, and the clinical status of the subject. 
NB: The re-initiation is not permitted for situations where the study drug should be 
permanently discontinued according to Table 6. In all cases of permanent study drug 
discontinuation, FU monitoring must be provided until signs and symptoms have resolved 
and changes in liver function are no longer regarded as clinically relevant or until medically 
indicated. 
5.1.13.6 Renal function 
Subjects must be permanently discontinued from study drug at any time throughout the 
study in the event of a rapid serum creatinine increase to > 150 µmol/L or rapid decrease 
in calculated creatinine clearance to < 30 mL/min (Cockroft-Gault) that cannot be rapidly 
reversed (by volume repletion or relief of urinary tract obstruction [according to etiology]). 
Any clinically relevant finding meeting the definition of an AE will be recorded 
accordingly in the eCRF. 
5.1.13.7 Ocular abnormalities 
In the event of suspected clinically significant findings (e.g., macular edema), an 
unscheduled OCT examination should be performed. In the case of macular edema, 
confirmed by the local ophthalmologist, the subject must be permanently discontinued 
from study drug and will be managed and followed up until resolution. The OSB will 
receive all information related to suspected cases of macular edema and will perform 
central review of OCT results and subject data. Any clinically relevant finding meeting the 
definition of an AE will be recorded accordingly in the eCRF. 
Subjects with active uveitis but without macular edema may continue on the study drug 
but will require additional ophthalmologic assessments as detailed below:

5.1.13.7.1 Guidance for monitoring and management of subjects with uveitis 
In case of suspicion of active uveitis (ocular pain, floaters, blurred vision, increased 
intraocular pressure) at Screening or during a scheduled ophthalmological assessment, 
fluorescence angiography (FA) should be performed (unless contra-indicated according to 
the ophthalmologist) in addition to the scheduled ophthalmological assessment and OCT, 
in order to characterize the uveitis. Subjects with suspicion of uveitis occurring during the 
study treatment but outside scheduled ophthalmological assessment should have a full 
ophthalmological assessment performed together with FA (unless contraindicated) as soon 
as possible. If active uveitis can be confirmed and macular edema can be ruled out, the 
subject may continue in the study without interrupting the study drug. Such subjects will 
need to be controlled by the ophthalmologist after 1 week, 2 weeks, and 4 weeks after the 
diagnosis of uveitis has been confirmed and then every 4 weeks throughout the study or 
until the condition has resolved. These ophthalmological exams should include full 
ophthalmological assessment (ophthalmological symptoms, assessment of best corrected 
visual acuity (Early Treatment Diabetic Retinopathy Study [ETDRS] charts), measurement 
of ocular pressure, preferably with Goldmann applanation tonometry, slitlamp examination 
of the anterior segment, and dilated indirect funduscopy) as well as OCT. FA may be 
repeated at the ophthalmologist’s discretion. The ophthalmologist will decide what 
treatment should be given to the subject. If the subject needs to be treated by 
immunosuppressants prohibited by the protocol, the study treatment has to be discontinued. 
If uveitis is progressing in spite of treatment, the investigator may consider interrupting or 
permanently discontinuing the study drug. 
5.1.13.8 Skin reactions 
Subjects must be permanently discontinued from study drug at any time throughout the 
study in the event of Stevens-Johnson syndrome or toxic epidermal necrolysis or drug 
reaction with eosinophilia and systemic symptoms. Subjects will be managed and 
followed-up until resolution. 
5.1.13.9 Peripheral neuropathy 
In case of development of symptoms suggestive of peripheral neuropathy such as bilateral 
numbness or tingling of hands or feet, the investigator should evaluate the subject and 
decide whether the diagnosis of peripheral neuropathy is likely. Such evaluation may 
include further clinical and/or neurophysiological diagnostic work-up for peripheral 
neuropathy according to the local practice. If, as a result of such evaluation, diagnosis of 
peripheral neuropathy is likely according to the investigator, the subject must 
be permanently discontinued from study drug, managed and followed up until resolution. 
Any clinically relevant finding meeting the definition of an AE will be recorded 
accordingly in the eCRF.

5.1.14 Elimination of teriflunomide 
5.1.14.1 Accelerated elimination procedure for teriflunomide 
Teriflunomide is eliminated slowly from plasma. Without an accelerated elimination 
procedure, it takes on average 8 months to reach plasma concentrations less than 
0.02 mg/L, although because of individual variations in drug clearance it may take as long 
as 2 years.  
At EOT, all subjects will have to undergo an accelerated elimination procedure consisting 
of either of the following procedures: 
• Administration of cholestyramine 8 g three times a day (i.e., every 8 h) for 11 days. If 
cholestyramine 8 g three times a day is not well tolerated, cholestyramine 4 g three 
times a day can be used.  
• Administration of 50 g oral activated charcoal two times a day (i.e., every 12 h) for 11 
days.  
If either elimination procedure is poorly tolerated, treatment days do not need to be 
consecutive unless there is a need to lower teriflunomide plasma concentration rapidly. It 
is permissible to switch from cholestyramine to activated charcoal (or vice versa) for 
reasons of tolerability.  
5.1.14.2 Compliance with accelerated elimination procedure 
Subjects’ compliance with the elimination procedure will be reviewed and assessed after 
each elimination procedure. The recommended compliance should include intake of 
33 doses of cholestyramine (8 g or 4 g) or 22 doses of activated charcoal (50 g). Plasma 
concentration of teriflunomide should not serve to assess compliance. Please refer to 
Sections 5.1.5.2 and 5.1.14.4 for timing of teriflunomide testing after EOT. 
Note: At FU1 and (abbreviated) FU2, plasma concentration of teriflunomide will not be 
measured. The testing should occur as described in Section 5.1.14.4. 
For subjects not entering the AC-058B303 extension study, subjects compliance will be 
reviewed at FU1. If the compliance has been assessed by the investigator as not sufficient 
at FU1, the subject will be asked to complete missing intakes or repeat the procedure. 
In such a case a new compliance assessment will be performed at FU2. If the compliance 
has been assessed as not sufficient at FU2, washout may be obtained through additional 
elimination procedures or by waiting for several months of natural elimination according 
to the subject’s preferences. Duration of continued contraception and timing of 
teriflunomide testing are described in Section 5.1.14.4. 
For subjects entering the AC-058B303 extension study, compliance will be reviewed at 
FU1. If the compliance has been assessed as not sufficient at FU1, the investigator will

decide if the elimination procedure should be repeated or missing intakes completed. In 
such a case a new compliance assessment will be performed at an abbreviated FU2. The 
abbreviated FU2 should be scheduled to allow enough time for completing the elimination 
procedure. The subject will only be eligible to enter the extension study AC-058B303 if 
the compliance was assessed as sufficient at FU1 or abbreviated FU2. Duration of 
continued contraception and timing of teriflunomide testing are described in the AC-
058B303 extension study protocol. If the compliance has been assessed as not sufficient at 
abbreviated FU2, the subject will not be eligible to enter the extension study AC-058B303. 
In such a case, teriflunomide washout may be obtained through additional elimination 
procedures or by waiting for several months of natural elimination according to the 
subject’s preferences. Duration of continued contraception and timing of teriflunomide 
testing are described in Section 5.1.14.4. 
5.1.14.3 Accountability of accelerated elimination procedure treatment 
At FU1 and FU2 (if accelerated elimination procedure was repeated after FU1), the number 
of bottles (activated charcoal) or sachets (cholestyramine) dispensed and returned, and the 
dosages administered are recorded on the non-IMP accountability log by the site staff. The 
accelerated elimination procedure treatment accountability is checked by the monitor at 
EOS. If the accountability cannot be performed (e.g., subject doesn’t return bottles or 
sachets), compliance will be evaluated based on discussions with the subject. 
5.1.14.4 Duration of continued contraception after EOT 
Contraception measures as described in Section 4.5, must be continued until at least 
6 weeks after the first of two consecutive tests showing a teriflunomide concentration 
< 0.02 mg/L. The testing of teriflunomide plasma concentration may be conducted for 
WOCBP and fertile male subjects, if needed, to confirm that contraception can be 
discontinued.  
For subjects not participating in the AC-058B303 extension study, plasma concentration 
of teriflunomide must not be measured earlier than 20 weeks after the last study drug intake, 
and provided the subject has been compliant with the accelerated elimination procedure of 
teriflunomide [see Section 5.1.14.2]. If the subject has not been compliant with the 
accelerated elimination procedure, testing for teriflunomide must not be done before 35 
weeks (i.e., 8 months) after last dose of study drug or EOS, whichever comes last.  
• If teriflunomide plasma concentration is as anticipated less than 0.02 mg/L, the site will 
receive notification that the test was successfully performed and that teriflunomide 
concentration is < 0.02 mg/L (actual concentration will not be displayed). A second test 
will be performed approximately 15 days after the first test to confirm the result. 
• If plasma teriflunomide concentration is more than 0.02 mg/L, site will receive 
notification that teriflunomide plasma level is ≥ 0.02 mg/L and the actual concentration 
will be displayed on the report. In such a case, the accelerated elimination procedure

may be repeated at the discretion of the investigator and the subject will be instructed 
to continue contraception until at least 6 weeks after the first of two consecutive tests 
that show teriflunomide plasma concentration level below 0.02 mg/L. 
For subjects continuing into the extension study AC-058B303 the applicable procedures 
for teriflunomide tests/retests and for continuation of contraception will be described in the 
AC-058B303 study protocol (separate protocol). 
The duration of contraception after EOT should follow the following rules: 
• For subjects continuing in the extension study AC-058B303 (separate protocol): 
the duration of contraception will be described in the AC-058B303 study protocol. 
• For subjects not continuing in the extension study AC-058B303 (both males and 
females): the duration of contraception should always be until at least 6 weeks after the 
first of two consecutive tests that show teriflunomide plasma concentration level below 
0.02 mg/L. Subjects who leave the study before achieving this should be instructed to 
follow this requirement outside the study.  
5.2 Previous and concomitant therapy 
5.2.1 Definitions 
A previous therapy is any treatment for which the end date is prior to the start of study (i.e., 
signing of informed consent). 
All therapy that is study concomitant (i.e., ongoing or initiated after signing of informed 
consent, and initiated before EOS visit) must be captured in the eCRF.  
A therapy that is concomitant to study-treatment is any treatment that is either ongoing at 
the start of study treatment or is initiated during the study treatment period, or up to 30 days 
after the end of study treatment. 
5.2.2 Reporting of previous/concomitant therapy in the eCRF 
The use of all study-concomitant therapy (including contraceptives or traditional and 
alternative medicines, i.e., plant-, animal-, or mineral-based medicines) will be recorded in 
the eCRF. The generic name, start/end dates of administration (as well as whether it was 
ongoing at start of treatment and/or EOS), route, dose, and indication will be recorded in 
the eCRF. 
Any previous administration of disease-modifying treatment for MS (IFN beta 1a [Rebif® 
- Avonex®, Plegridy®], IFN beta 1b [Betaseron®], glatiramer acetate [Copaxone®, 
Glatopa®], fingolimod [Gilenya®], dimethyl fumarate/BG-12 [Tecfidera®], natalizumab 
[Tysabri®], alemtuzumab [Lemtrada®]) at any time prior to screening will be recorded in

the previous MS treatment form of the eCRF. The start date, end date, dose, route, 
frequency, and reason for discontinuation will be recorded in the eCRF.  
The therapies used for the treatment of relapses experienced by the subject in the past 
24 months will be recorded in the previous MS treatment form of the eCRF 
(e.g., corticosteroids, ACTH). For each therapy, the start date, end date, reason for 
discontinuation, dose, route, and frequency of administration will be recorded in the eCRF. 
Any previous relevant therapy as per principal investigator / treating neurologist judgment 
(e.g., therapies listed in exclusion criteria, therapies for relevant medical history) will be 
recorded in the previous therapy form of the eCRF. 
5.2.3 Recommended concomitant therapy 
Treatment of relapses: 
• If a relapse requires treatment with corticosteroids, methylprednisolone 1 g i.v. daily 
for 3 to 5 days is recommended. Treatment with other corticosteroids, another dose, 
other routes of administration, or ACTH is not recommended unless deemed absolutely 
necessary and must be documented in the patient charts by the investigator. Oral taper 
with corticosteroids should not be administered in any case. 
• Treatment of relapses with plasma exchange (i.e., plasmapheresis, cytapheresis) is 
prohibited. 
5.2.4 Allowed concomitant therapy 
• Dalfampridine (synonymous with fampridine) on a stable dose for at least 90 days prior 
to randomization and during double-blind treatment. Dalfampridine therapy must not 
be started or increased in dose during the study. Stopping or decreasing the dose of 
dalfampridine during the study should only take place if deemed absolutely necessary 
and must be documented in the patient charts by the investigator; 
• Administration of i.v. atropine in the event of symptomatic bradycardia; 
• Short-acting ß2-agonists for respiratory symptoms and/or reduced pulmonary function 
during study drug treatment; 
• QT-prolonging drugs with known risk of Torsades de Pointes should be used with 
caution since ponesimod may potentially enhance their effect on QT interval [guidance 
is provided in Appendix 3]; 
• Vaccination with non-live vaccines. Subjects receiving non-live vaccination while on 
study treatment will have 5 mL of blood drawn prior to and ≥ 3 weeks after vaccination 
in order to assess changes in vaccine-specific antibody titers from pre- to 
post-vaccination. Samples will be analyzed at the end of the study [see Section 3.1.6.4].

• The following medications should be administered with caution due to potential 
interaction with teriflunomide:  
− Teriflunomide is an inhibitor of cytochrome P450 (CYP)2C8 in vivo: CYP2C8 
substrates such as repaglinide, paclitaxel, pioglitazone, or rosiglitazone should 
be carefully monitored when co-administered with study drug treatment as they 
may have higher exposure; 
− Teriflunomide may be a weak inducer of CYP1A2 in vivo: medicinal products 
metabolized by CYP1A2 such as duloxetin, alosetron, theophylline and 
tizanidine should be used with caution during study drug treatment, as reduction 
of the efficacy of these products may be observed; 
− A 25% decrease in peak INR was observed when teriflunomide was 
co-administered with warfarin as compared with warfarin alone. Therefore, 
when warfarin is co-administered with study drug treatment, close INR FU and 
monitoring is recommended;  
− Teriflunomide is an inhibitor of organic anion transporter (OAT)3 in vivo: when 
study drug treatment is co-administered with substrates of OAT3, such as 
cefaclor, benzylpenicillin, ciprofloxacin, indometacin, ketoprofen, furosemide, 
cimetidine, zidovudine, caution is recommended; 
− Co-administration 
of 
substrates 
of 
breast 
cancer 
resistant 
protein 
(e.g., topotecan, sulfasalazine, daunorubicin, doxorubicin) and the OAT 
polypeptide family (e.g., nateglinide, repaglinide, rifampicin) and especially 
HMG-CoA reductase inhibitors (e.g., rosuvastatin, simvastatin, atorvastatin, 
pravastatin) with the study drug treatment should be undertaken with caution. 
Subjects should be closely monitored for signs and symptoms of excessive 
exposure to these medicinal products, and reduction of the dose of these 
medicinal products should be considered; 
− Rifampicin and other known potent CYP and transporter inducers such as 
carbamazepine, phenobarbital, phenytoin and St John’s Wort may result in a 
decrease in teriflunomide exposure. Co-administration of these drugs with 
study drug treatment should be used with caution.  
• Other treatments considered necessary for the subject’s wellbeing and not categorized 
as prohibited concomitant medications. 
5.2.5 Forbidden study-treatment-concomitant therapy 
• 
Systemic corticosteroids and ACTH, except for the treatment of MS relapses [see 
Section 5.2.3] and for short-term treatment (up to 2 weeks per treatment cycle with at 
least 8 weeks’ interval between treatment cycles and no more than 8 weeks during the

whole study duration) with low dose of corticosteroid (up to 10 mg of prednisone 
equivalent daily) or inhaled corticosteroids for pulmonary conditions; 
• 
Disease-modifying drugs for MS other than prescribed as per protocol; 
• 
Immunosuppressive treatment (e.g., cladribine, mitoxantrone or other systemic 
immunosuppressive treatments such as azathioprine, cyclophosphamide, cyclosporine 
or methotrexate); 
• 
i.v. immunoglobulin; 
• 
Plasmapheresis, cytapheresis, or total lymphoid irradiation; 
• 
Vaccination with live vaccines; 
• 
β-blockers, diltiazem, verapamil, digoxin, or any other anti-arrhythmic or 
HR-lowering systemic therapy [non-exhaustive list of drugs provided in  
Appendix 4]; 
• 
Cholestyramine or activated charcoal unless needed for an accelerated elimination 
procedure;  
• 
Any other investigational drug; 
• 
Any investigational therapeutic procedure for MS (e.g., stent placement or angioplasty 
for chronic cerebrospinal venous insufficiency, stem-cell transplantation). 
In the event that a subject takes any of these forbidden medications, the investigator must 
contact the sponsor to discuss further FU actions including stopping/interrupting study 
treatment as appropriate. 
6 
STUDY ENDPOINTS 
For each of the study endpoints, baseline is defined as the last value recorded prior to 
randomization (the actual visit used as baseline might be different across endpoints). 
6.1 Efficacy endpoints 
6.1.1 Primary efficacy endpoint(s) 
The primary endpoint is ARR. This endpoint is based on the number of confirmed relapses 
per subject-year. 
Definition of relapse  
• A relapse is defined as new, worsening or recurrent neurological symptoms that occur 
at least 30 days after the onset of a preceding relapse, and that last at least 24 h, in the 
absence of fever or infection. 
The new, worsening or recurrent neurological symptoms are to be evaluated by the treating 
neurologist and, if all the elements of the above definition have been verified, and in the 
absence of another, better explanation of the subject’s symptoms, the event is considered

as a relapse [see Section 7.2.2]. The onset date of the relapse corresponds to the onset date 
of the symptoms. 
• A relapse will be confirmed by the treating neurologist only when the subjects’ 
symptoms are accompanied by an increase in EDSS/FS scores, which is consistent with 
the subject’s symptoms, from a previous clinically stable EDSS/FS assessment (i.e., 
performed at least 30 days after the onset of any previous relapse), obtained by the 
efficacy assessor and consistent with the following: 
− An increase of at least half a step (0.5 points; unless EDSS = 0, then an increase of 
at least 1.0 points is required) or  
− An increase of at least 1.0 point in at least two FS scores, or  
− An increase of at least 2.0 points in at least one FS score (excluding bladder/bowel 
and cerebral).  
6.1.2 Secondary efficacy endpoints 
There are four secondary efficacy endpoints, which will be analyzed as per the statistical 
testing strategy outlined in Section 11.3.1:  
• 
Change from baseline to Week 108 in fatigue-related symptoms as measured by 
the symptoms domain of the FSIQ–RMS 
 
• 
Cumulative number of combined unique active lesions (CUAL) from baseline to 
Week 108 
Definition: CUAL are new Gd+ T1 lesions plus new or enlarging T2 lesions (without 
double-counting of lesions). 
• 
Time to 12-week CDA from baseline to EOS 
Definition: A 12-week CDA is an increase of at least 1.5 in EDSS for subjects with a 
baseline EDSS score of 0.0 or an increase of at least 1.0 in EDSS for subjects with a 
baseline EDSS score of 1.0 to 5.0, or an increase of at least 0.5 in EDSS for subjects with 
a baseline EDSS score ≥ 5.5 which is to be confirmed after 12 weeks.  
Baseline EDSS is defined as the last EDSS score recorded prior to randomization. The 
initial EDSS increase, meeting the above criteria, is defined as the onset of disability 
accumulation.  
All EDSS measurements (with or without relapse, at a scheduled or unscheduled visit) will 
be used to determine the onset of disability accumulation. However, EDSS scores used for 
confirmation of disability accumulation must be obtained at a scheduled visit 
(i.e., unscheduled visits cannot be used as confirmatory visits) outside any ongoing relapse. 
In this context, relapse duration is defined as period between start and end dates if available

and limited to 90 days from onset if end date is not available or duration is longer than 90 
days.  
In order to confirm that the EDSS increase is persistent, all EDSS measurements between 
the onset and the 12-week EDSS confirmation (minus 7-day visit time-window) need to 
show an increase in EDSS, meeting the criteria for accumulation of disability as defined 
above.  
• 
Time to 24-week CDA from baseline to EOS 
Definition: A 24-week CDA is an increase of at least 1.5 in EDSS for subjects with a 
baseline EDSS score of 0.0 or an increase of at least 1.0 in EDSS for subjects with a 
baseline EDSS score of 1.0 to 5.0, or an increase of at least 0.5 in EDSS for subjects with 
a baseline EDSS score ≥ 5.5 which is to be confirmed after 24 weeks.  
Baseline EDSS is defined as the last EDSS score recorded prior to randomization. The 
initial EDSS increase, meeting the above criteria, is defined as the onset of disability 
accumulation.  
All EDSS measurements (with or without relapse, at a scheduled or unscheduled visit) will 
be used to determine the onset of disability accumulation. However, EDSS scores used for 
confirmation of disability accumulation must be obtained at a scheduled visit (i.e., 
unscheduled visits cannot be used as confirmatory visits) outside any ongoing relapse. In 
this context, relapse duration is defined as period between start and end dates if available 
and limited to 90 days from onset if end date is not available or duration is longer than 90 
days.  
In order to confirm that the EDSS increase is persistent, all EDSS measurements between 
the onset and the 24-week EDSS confirmation (minus 7-day visit time-window) need to 
show an increase in EDSS, meeting the criteria for accumulation of disability as defined 
above. 
6.1.3 Other efficacy endpoints 
MRI-based exploratory endpoints: 
• 
Percent change in brain volume (PCBV) from baseline to Week 108 
Definition: Longitudinal brain volume measurements are derived from MRI scans by using 
Structural Image Evaluation, using Normalization, of Atrophy methodology (SIENA) 
[Smith 2001, Smith 2002]. 
• 
Number of MRI lesions (Gd+ T1 lesions) at Week 60 and Week 108 
• 
Cumulative number of new or enlarging T2 lesions from baseline to Week 108 
• 
Change from baseline to Week 60 and Week 108 in the volume of MRI lesions 
(T2 lesions, T1 hypointense lesions)

of the first confirmed relapse.  
• 
Absence of confirmed relapses from baseline to Weeks 60 and 108 
• 
Change from baseline by visit up to Week 108 in EDSS 
•

STUDY ASSESSMENTS 
All study assessments are performed by a qualified study staff member: medical, nursing, 
or specialist technical staff, and are recorded in the eCRF, unless otherwise specified. Study 
assessments performed during unscheduled visits will also be recorded in the eCRF.  
If the principal investigator delegates any study procedure/assessment for a subject, 
e.g., ECG, MRI, blood sampling etc., to an external facility, she/he should inform Actelion 
to whom these tasks are delegated. The set-up and oversight will be agreed upon with 
Actelion. The supervision of any external facilities remains under the responsibility of the 
principal investigator. 
Calibration certificates for the following devices used to perform study assessments must 
be available prior to the randomization of the first subject:  
• Temperature measurement devices for study medication storage area and lab sample 
storage (e.g., freezer).

• Spirometer; in addition, a copy of the calibrations check (syringe check) of the day of 
measurement must be stored and a log of calibration check results must be maintained 
at the site [see Section 7.3.5]. 
• DLCO gas analyzer (if applicable); in addition, a copy of the calibrations of the day of 
test must be stored and a log of calibration results must be maintained at the site. 
Frequent testing involving the same healthy subject control (biological quality check) 
or a DLCO simulator will ensure continuous monitoring of the gas analyzer 
measurement accuracy over time [see Section 7.3.6].  
• ECGs. 
• BP monitoring device. 
• MRI; in addition, prior to the start of the study, each MRI site must be qualified by 
MIAC [see Section 7.2.3]. 
7.1 Baseline assessments, including demographics 
7.1.1 Informed consent Visit 1 (Screening) 
Prior to performing any study-specific procedures or assessments, the subject must provide 
written informed consent to participate in the study. If the signing of informed consent and 
performance of the first study-specific procedures or assessments take place on the same 
day, it must be clear from the source documents that informed consent was obtained prior 
to any study-specific procedures being performed. If a study-specific procedure or 
assessment has been performed as part of routine assessments and the results are available 
prior to the subject’s signing of informed consent, such procedure or assessment may be 
used to assess eligibility and does not have to be repeated (CXR [see Section 7.3.7]). In 
such cases, it must be clear from the source document when and for which reason the 
assessment was done prior to the signing of the informed consent. It is the responsibility 
of the principal investigator / treating neurologist to explain the study in all its aspects to 
the subject and obtain her/his informed consent. The informed consent process will be 
documented in the investigator site file (ISF). The language used in the oral and written 
information about the trial, and including the ICF, will be provided in a language that is 
fully understandable to the subject. 
Separate informed consent must be obtained from those subjects participating in the DLCO, 
non-conventional MRI, and patient preference sub-studies. 
For subjects who provide informed consent but are subsequently not randomized into the 
study, the reasons for not being randomized will be recorded in eCRF.

7.1.2 Baseline demographics and disease characteristics 
Baseline demographics (sex, age, race, body weight, and height) are to be recorded in the 
eCRF at Visit 1 (Screening). Complete, clinically relevant medical history and current 
conditions, as well as smoking status and MS disease characteristics [see Section 4.6] are 
to be documented in the eCRF. 
7.1.3 Study-concomitant therapies 
All study-concomitant therapy (including contraceptives and traditional and alternative 
medicines, i.e., plant-, animal-, or mineral-based medicines) taken by the subject from the 
signing of informed consent until the end of their participation in the study (i.e., EOS) will 
be recorded in the Concomitant Therapies pages of the eCRF. This includes all ongoing 
therapies and those initiated or stopped during this period. The corresponding dates of 
initiation and discontinuation will be recorded. 
7.2 Efficacy assessments 
7.2.1 Neurological evaluation 
EDSS and FS scores [Kurtzke 1983] are based on a standard neurological examination for 
assessing neurologic disability and impairment in MS. The seven FS scores are ordinal 
clinical rating scales ranging from 0 to 5 or 6, assessing visual, brain stem, pyramidal, 
cerebellar, sensory, bowel and bladder, and cerebral functions while ambulation is an 
ordinal scale ranging from 0 to 12 assessing walking distance and assistance. The ratings 
of the individual FS scores are then used, in conjunction with ambulation score, to obtain 
the EDSS score. EDSS is an ordinal clinical rating scale ranging from 0 (normal 
neurological examination) to 10 (death due to MS) in half-point increments. 
EDSS and FS assessments will be performed at Visits 1 (Screening), 2 (Baseline), 6 to 
13 (Week 12 and every 12 weeks thereafter), 14 (EOT), 16 (FU2), and at any unscheduled 
visit in the event of relapses (R1, R2, etc.) or other unscheduled visits (U1, U2, etc.). If 
applicable, EDSS and FS will also be assessed at the corresponding visits in the PTOP 
(Visits 6A to 14A). 
EDSS and FS assessments will only be performed by the efficacy assessor who should 
preferably maintain this role for a given subject throughout the study [see Section 3.3.3]. 
The efficacy assessor must not consult prior EDSS/FS scores when performing the current 
EDSS/FS assessment. In no case will the treating neurologist alter the EDSS/FS score 
obtained by the efficacy assessor. The examination will be based on the modified 
neurological examination “Neurostatus” [Appendix 2] using the corresponding scoring 
documents. The EDSS/FS scoring will be recorded in the eCRF. NB: Fatigue, which is an 
optional part of the Neurostatus assessment will not contribute to the Cerebral FS score.

7.2.2 Detection and evaluation of relapses 
Detection and evaluation of relapses will be done as follows [Figure 7]: 
Step 1: At every study visit, subjects are reminded to contact their principal investigator / 
treating neurologist immediately in the event of the appearance of any new or worsening 
neurological symptoms. In addition, the site will contact the subject in between the 
12-weekly visits (e.g., Visit 6–Week 12, Visit 7–Week 24,…) even after possible 
premature discontinuation from the study treatment (e.g., Visit 6A–Week 12 in the PTOP, 
Visit 7A–Week 24 in the PTOP,…) in order to proactively inquire about any new or 
worsened neurological symptoms. These telephone calls will be conducted either at Weeks 
18, 30, 42, 54, 66, 78, 90, and 102 (+/− 7 days), or 6 weeks after the last 12-weekly visit 
(+/− 7 days). If applicable, the contacts may occur on site during blood sampling visits. 
Whenever a subject experiences any new or worsening neurological symptoms between 
visits, he/she must contact the principal investigator / treating neurologist, study nurse or 
clinical coordinator as soon as possible in order to complete a telephone questionnaire for 
relapse assessment [see Appendix 17]. 
If, during the call from the site inquiring about symptoms suggestive of potential new 
relapses, the subject reports occurrence of such symptoms, a telephone questionnaire for 
relapse assessment will also be completed.  
If a relapse is suspected, the subject will be required to come to the site for an unscheduled 
relapse assessment visit. The completed telephone questionnaire will be collected in the 
eCRF. 
Step 2: At every scheduled and unscheduled visit (limited to unscheduled visits when the 
subject will meet with the principal investigator / treating neurologist, but not at other 
unscheduled visits conducted for repeat testing (e.g., ALT or AST PFT …), the principal 
investigator / treating neurologist will interview the subject to determine whether or not a 
relapse may have occurred since last visit using a dedicated relapse assessment 
questionnaire [see Appendix 17] and the relapse symptom form [see Appendix 18]. 
Based on the interview and examination, the principal investigator / treating neurologist 
will determine if symptoms are likely to be due to a relapse (i.e., all elements from the 
relapse definition in Section 6.1.1 have been verified and, in the absence of another, better 
explanation of the subject’s symptoms), the subject will be referred to the efficacy assessor 
for an EDSS assessment. (Note: At scheduled visits the EDSS assessment planned for this 
visit will be used). The completed questionnaire [see Appendix 12] and the outcome of the 
examination [see Appendix 13] will be collected in the eCRF. 
Step 3: ‘The efficacy assessor will perform the EDSS/FS assessment within 7 days from 
the onset of new or worsening neurological symptom(s) [see Section 7.2.1].

Important note: EDSS and FS assessments will be performed only by the efficacy 
assessor. The efficacy assessor must not consult prior EDSS/FS scores when performing 
the current EDSS/FS assessment. In no case will the treating neurologist alter the EDSS/FS 
score obtained by the efficacy assessor. If the relapse requires treatment with 
corticosteroids [see Section 5.2.3], treatment should be initiated as early as recommended 
by local clinical practice. The blinded neurological examination by the efficacy assessor 
must always be performed prior to the treatment start.  
Step 4: The treating neurologist will review the EDSS/FS score obtained by the efficacy 
assessor and determine presence or absence of qualifying increase in EDSS/FS (i.e., an 
increase of the magnitude described in Section 6.1.1 from a previously clinically stable 
EDSS/FS score and consistent with the subject’s new symptoms). Based on this review, 
the treating neurologist will decide if the relapse is confirmed or not, according to the 
protocol definition of confirmed relapse [see Section 6.1.1]. 
Once step 1 of the relapse detection has been initiated (whether by subject calling the site, 
by interview of the subject at scheduled visit, or by scheduled calls from the site to the 
subject), the final result of the relapse detection and confirmation process will be captured 
as one of the following 3 outcomes: no relapse, unconfirmed relapse, or confirmed relapse. 
New or worsened neurological symptoms reported by the subject and for which there is 
another, better explanation for the subject’s current symptoms than an MS relapse will be 
captured on an AE page. 
All MS relapses, whether or not confirmed, must be reported on specific relapse pages of 
the eCRF. MS relapses and associated symptoms are not to be entered on the AE page of 
the eCRF with the following exceptions: 
• MS relapses with fatal outcome (these must always be recorded as AEs on the AE page 
in addition to being reported as SAEs).  
• MS relapses that, in the view of the investigator, warrant specific notice due to unusual 
frequency, severity or remarkable clinical manifestations (these should be reported as 
AEs on the AE page of the eCRF and, if applicable, on the SAE form).

7.2.3 MRI evaluations 
MRI scans will be performed at Visits 2 (Baseline), 10 (Week 60), and 14 (EOT) and at 
any unscheduled visit (U1, U2, etc.). If applicable, MRI scans will also be performed at the 
corresponding visits in the PTOP (Visits 10A and 14A). Testing at all visits may be 
performed up to 7 days prior to or after the visit date. In case of premature study treatment 
discontinuation, the MRI at EOT does not need to be performed if the EOT visit occurs 
within less than 4 weeks of the MRI assessment at Visit 10 (Week 60). 
MRI variables include the number and volume of new and total Gd+ lesions on 
T1-weighted MRI scans, number of new and enlarging lesions and lesion volume on 
T2-weighted MRI, and global measures of loss of brain tissue. 
T1-weighted imaging before and after i.v. administration of 0.1 mmol/kg body weight 
(= 0.2 mL/kg) of Gd as well as PD-T2-weighted imaging will be performed. Gd may cause 
nausea and vomiting and in very rare cases allergic reactions that could require immediate 
anti-anaphylactic therapy (such as steroids, epinephrine/adrenaline, etc.). 
All MRI data will be analyzed by the MIAC, c/o University Hospital Basel, Switzerland. 
MRI scans which are of unacceptable quality for central reading evaluation will be 
repeated.  
Prior to the start of the study, each MRI site must be qualified by MIAC. To be qualified, 
each MRI site will perform a dummy scan according to the parameter settings defined in 
the study MRI manual (separate document) and submit the image data to the MIAC who 
will assess the image quality, the quality of the data transfer, and the compatibility with the 
electronic data processing and will qualify the site accordingly. The dummy scan will not 
use contrast agent and will be performed on a volunteer or patient, having signed a specific 
informed consent for this MRI assessment. Once qualified, each MRI site must maintain 
all the study-specific parameter settings unchanged throughout the study. 
Detailed instructions on procedures, standardization, qualification, recording, and transfer 
of data, etc., will be provided in the study MRI manual (separate document).  
Lesion count of MRI performed within 24 months prior to the study will be recorded on 
the MS history page of the eCRF. These scans will not be analyzed by the MIAC.  
Incidental, non-MS-related findings identified by central reading will be communicated to 
the principal investigator / treating neurologist. Furthermore, all MRI scans performed for 
the study must be reviewed and documented for safety by the local neuroradiologist. The 
principal investigator / treating neurologist must be informed of any findings of concern 
for the subject’s safety including non-MS-related findings detected on the MRI scan, but 
efficacy-related MRI results (e.g., lesion counts) will not be communicated to study staff 
or to the subject, unless deemed necessary for maintaining safety of the subject. Study 
participants with clinically relevant findings on MRI will be followed up until establishing

the final diagnosis and managed as per local medical practice. Other diagnostic procedures 
may be performed as a FU assessment according to local standard procedures when 
considered necessary by the investigator. Incidental clinically relevant findings on MRI 
will be reported in the Medical History or as AE, as applicable. 
7.2.4 Supplementary non-conventional MRI sub-study 
Supplementary non-conventional MRI scans assessing MTR and DIR will be performed at 
selected sites with adequate equipment and expertise at the same timepoints as the 
conventional MRI scan described above. Only subjects who consent under a separate 
informed consent for non-conventional MRI will participate in the sub-study. It is 
anticipated that up to 300 subjects will participate to the sub-study. 
Similarly to the conventional MRI scans, data will be interpreted by MIAC. 
Detailed instructions on procedures, standardization, qualification, recording, and transfer 
of data, etc., will be provided in the study MRI manual (separate document). 
7.2.5 MSFC 
The MSFC score consists of 3 clinical examinations: the Timed 25-Foot Walk, the Paced 
Auditory Serial Addition Test (PASAT-3” version), and the 9-Hole Peg Test (9-HPT). The 
timed 25-foot (7.62 meters) walk is a quantitative measure of lower extremity function. 
The 9-HPT is a quantitative measure of upper extremity (arm and hand) function. The 
PASAT is a measure of cognitive function that specifically assesses auditory information 
processing speed and flexibility, as well as calculation ability. 
MSFC will be assessed pre-randomization and at Visits 6, 7, 10, 12 (Weeks 12, 24, 60, 
and 84), and 14 (EOT).  
During the pre-randomization Period, two practice tests and a third test serving as baseline 
assessment will be performed. Ideally, the three tests should be performed  
≥ 5 days apart (i.e., second test practice ≥ 5 days from first practice test and third test 
serving as baseline ≥ 5 days from second practice test). The first test practice may be done 
at Visit 1 (Screening), the second test practice may be done at Visit 2 (Baseline) and the 
third test, serving as baseline, may be performed pre-dose at Visit 3 (Randomization). 
MSFC will be administered in combination with SDMT [see Section 7.2.6] in the following 
sequence: 
1. Timed 25-Foot Walk (7.62 meter)  
2. 9-HPT 
3. PASAT 
4. SDMT

A full description of the administration of the scale, sequence of tests and scoring will be 
given in a separate document provided to each site. The test administrator will be trained 
on the test administration before the initiation of the site. The test will only be administered 
by a trained administrator.  
A more comprehensive description of the test and its administration is provided in 
Appendix 7. 
7.2.6 Symbol Digit Modalities Test 
The SDMT [Smith 1982, Benedict 2006] measures attention and processing speed much 
like the PASAT. It will be administered along with the MSFC at pre-randomization and at 
Visits 6, 7, 10, 12 (Weeks 12, 24, 60, 84), and 14 (EOT).  
During the pre-randomization Period, two practice tests and a third test serving as baseline 
assessment will be performed. Ideally, the three tests should be performed  
≥ 5 days apart (i.e., second test practice ≥ 5 days from first practice test and third test 
serving as baseline ≥ 5 days from second practice test). The first test practice may be done 
at Visit 1 (Screening), the second test practice may be done at Visit 2 (Baseline) and the 
third test serving as baseline may be performed pre-dose at Visit 3 (Randomization). 
The SDMT includes a reference key of nine symbols, each paired with a single digit. Below 
the reference key are rows of the symbols arranged randomly. The subject is given 
90 seconds to say the number that corresponds to each symbol. The test administrator 
records the answers and the number of correct answers is recorded as the score.  
The SDMT will be performed after the MSFC. Study personnel will be trained to 
administer and score the SDMT. 
A sample of the SDMT is provided as Appendix 8. The rater will record the subject’s 
responses on a validated paper form that will be collected and transcribed in the eCRF. 
Actelion Pharmaceuticals has been granted a license agreement for the use of the SDMT. 
The individual questionnaires will be completed by all subjects in all countries as it does 
not require language translations. 
7.2.7 FSIQ-RMS 
The FSIQ-RMS is a 20-item PRO measure that was developed by Actelion to evaluate 
fatigue-related symptoms and the impacts of those symptoms on the lives of people with 
RMS. The development of FSIQ-RMS is in accordance with the requirements set forth in 
the Final Guidance to the Industry on Subject Reported Outcomes: Use in Medical Product 
Development to Support Label Claims [FDA 2009a]. The questionnaire will be 
administered in an electronic format and consists of two separate domains:

• The FSIQ-RMS symptom domain (FSIQ-RMS-S) consists of seven items assessing 
fatigue-related symptoms with a recall period of 24 h measured on an 11-point numeric 
rating scale; the symptom domain score ranges from 0 to 77 with a higher score 
indicating greater fatigue. This domain (i.e., section 1 of the questionnaire) will be 
completed on 7 consecutive days. 
• The FSIQ-RMS impact domain (FSIQ-RMS-I) consists of 13 items assessing 
impacts of fatigue-related symptoms with a recall period of 7 days measured on a 
5-point Likert scale, ranging from no impact to extreme impact; the impact domain 
score ranges from 0 to 65 with a higher score indicating greater impact. As the impact 
domain of the FSIQ-RMS (i.e., section 2 of the questionnaire) has a 7-day recall period, 
it will only be completed on the last day (i.e., seventh day) of completion of section 1.  
FSIQ-RMS will be completed during the pre-randomization period, at Visits 6, 7, 10, and 
12 (Weeks 12, 24, 60, 84), 14 (EOT), and at unscheduled visits due to relapses (R1, R2, 
etc.) or other unscheduled visits (U1, U2, etc.) as described below. If applicable, 
FSIQ-RMS will also be performed at the corresponding visits in the PTOP. 
The completion of the FSIQ-RMS during the pre-randomization period will be done as 
follows: At Visit 1 (Screening), subjects who appear eligible based on the assessments 
made during this visit (but prior to the results from the laboratory assessments are received) 
will be provided with the electronic device containing the FSIQ-RMS.  
Once the results from the laboratory assessments confirm the subject’s eligibility, and 
provided no other assessment performed in the meantime excludes the subject, the site 
coordinator will contact and ask the subject to start the completion of the FSIQ-RMS. 
At home, the subject will complete the symptom domain of the FSIQ-RMS for 7 days 
(i.e., section 1 of the questionnaire). On the seventh day, the subject will also complete the 
impact domain of the FSIQ-RMS (i.e., section 2 of the questionnaire). The information 
captured from this assessment will be used as the baseline data for the FSIQ-RMS. Ideally, 
the FSIQ-RMS will be completed during the 7 consecutive days preceding the 
randomization.  
After randomization, the symptoms domain of the FSIQ-RMS (i.e., section 1 of the 
questionnaire) will be completed by the subject at home on a daily basis, starting in the 
evening of the day of a visit when the FSIQ-RMS is administered (Day 1 of questionnaire 
administration cycle) and during the 6 subsequent days (i.e., over 7 days in total). Subjects 
will return the completed FSIQ-RMS diary at the next scheduled visit. On the seventh day, 
the subject will also complete the impact domain of the FSIQ-RMS (i.e., section 2 of the 
questionnaire). If applicable, at the end of the PTOP, the FSIQ-RMS will be completed 
prior to Visit 14A (Week 108), ideally, during the 7 consecutive days preceding the visit.

The data from the electronic device will be collected by the vendor who will send the results 
to Actelion. The individual questionnaires will be completed only in countries for which 
validated translations are available. 
A sample of the FSIQ-RMS is provided as Appendix 9. 
7.2.8 Patient preferences 
Patient preferences for several treatment outcomes will be assessed in a subset of 
approximately 360 subjects using an electronic questionnaire developed by Actelion. 
Subjects will be recruited at selected sites in countries for which translations are available. 
Only subjects who consent under a separate informed consent for MS Patient Preference 
Questionnaire will participate in the sub-study. The MS Patient Preference Questionnaire 
will be completed at home twice during the pre-randomization period (after Visits 1 and 2 
[Screening, Baseline]), and during the follow-up period (before Visit 15, FU1) using an 
electronic device. All questionnaire responses will be electronically transferred to the 
Actelion database. Support for navigating the questionnaire will be provided as a tutorial 
within the electronic device. No guidance as to the content of the responses will be provided 
to the subject. 
A sample of the MS Patient Preference Questionnaire is provided as Appendix 14. 
7.2.9 Patient’s Global Impression of Severity of Fatigue 
The PGI-S of Fatigue assesses the subject’s fatigue severity on a given day. The scale is 
scored by the subject on an 11-point numeric rating scale ranging from 0 to 10, anchored 
at 0 = “Not severe at all” and 10 = “Very severe”. The questionnaire will be administered 
in an electronic format. 
PGI-S of Fatigue will be completed during the pre-randomization period at Visit 2 
(Baseline), at Visits 6, 7, 10, and 12 (Weeks 12, 24, 60, 84), 14 (EOT), and at unscheduled 
visits due to relapses (R1, R2, etc.) or other unscheduled visits (U1, U2, etc.). If applicable, 
PGI-S will also be performed at the corresponding visits in the PTOP. 
The individual questionnaires will be completed only in countries for which validated 
translations are available. 
It is recommended that the PGI-S of Fatigue is completed prior to any clinical assessments 
and before study drug exposure on the day of the visit. Preferably, subjects would complete 
the PGI-S of Fatigue while waiting for their appointment before any interaction with health 
care providers to avoid any potential bias or impact of interventions in their responses. 
A sample of the PGI-S of Fatigue is provided as Appendix 12.

7.2.10 Clinician’s Global Impression of Change of patient’s relapsing multiple 
sclerosis 
The CGI-C of patient’s relapsing MS requires the clinician to assess the change in subject’s 
relapsing MS severity compared to Baseline (Visit 2). The question is scored by the 
investigator on a 7-point Likert scale ranging from 1 to 7, anchored at 1 = “Very much 
improved” and 7 = “Very much worse”. The questionnaire will be completed on a paper 
form and subsequently transcribed in the eCRF. 
CGI-C of patient’s relapsing MS will be completed at Visits 6, 7, 10, and 12 (Weeks 12, 
24, 60, 84), 14 (EOT), and at unscheduled visits due to relapses (R1, R2, etc.) or other 
unscheduled visits (U1, U2, etc.). If applicable, CGI-S will also be performed at the 
corresponding visits in the PTOP. 
A sample of the CGI-C of patient’s relapsing MS is provided as Appendix 13.  
7.3 Safety assessments 
The definitions, reporting and FU of AEs, SAEs and potential pregnancies are described in 
Section 10. 
7.3.1 12-lead electrocardiogram 
A standard 12-lead ECG will be recorded at all scheduled study visits with the subject in a 
fully rested supine position after the subject has been allowed to rest for a minimum of 5 
min prior to the measurement. Pre-dose ECG may also be performed at unscheduled visits 
(U1, U2, etc.).  
Digital 12-lead ECG devices will be provided to each site by the central ECG laboratory 
for the duration of the study. Digital ECG recording must be performed for all subjects 
according to the study protocol schedule. The data records will be sent to the central ECG 
laboratory for central reading. The reports from the central ECG laboratory will be sent to 
the site within a few days. In addition, at all sites where the first-dose administrator is not 
adequately experienced in interpreting ECGs, at Visit 3 (Day 1) and on the day of 
re-initiation of study drug when post-dose monitoring will be required, the pre-dose and 
post-dose ECGs required for evaluation of discharge criteria will be transmitted to the 
central ECG laboratory for expedite evaluation, and the ECG report will be returned to the 
site within approximately 1–2 h from transmittal.  
Details will be provided in the ECG laboratory manual. 
At Visit 3 (Day 1) and visits for re-initiation of study drug when post-dose monitoring will 
be required, the 12-lead ECG monitoring will be performed under the responsibility of the 
first-dose administrator. At all other visits, it will be performed under the responsibility of 
the treating neurologist or the first-dose administrator, depending on the site setting [see

Section 3.3.2 and Section 3.3.4]. The first-dose administrator will ensure that blinded study 
personnel at the study site, such as the treating and evaluating neurologists, clinical 
coordinator / study nurse, and other personnel involved in the clinical care and 
management of study subject, do not have access to post-dose ECG interpretation reports 
at Visit 3 (Day 1) and at visits for re-initiation of study drug when post-dose monitoring 
will be required (Visits I1, I2, etc.).  
The following variables will be evaluated: HR (bpm), PR (ms), QRS (ms), QT (ms), 
QTc (ms), and any ECG findings. QTC (ms) will be calculated according to Bazett’s and 
Fridericia’s formula (QTcB = QT/(RR) ½ and QTcF = QT/(RR) ⅓, respectively). 
At Visit 3 pre-dose (Day 1), the first-dose administrator must provide the ECG results and 
interpretation to the principal investigator / treating neurologist and support her/him, if 
requested, to make a final decision on the subject’s eligibility according to the 
inclusion/exclusion criteria. At Visit 3 (Day 1), the pre-dose ECG must be performed prior 
to

(e.g., HR < 50 bpm, presence of second-degree AV block Mobitz Type II or third-degree 
AV block, or a QTcF interval > 470 ms (females), > 450 ms (males), see Section 4.4) must 
be ruled out. 
During the treatment period ECGs must be performed at pre-dose. Additionally, at Visit 6 
(Week 12) during the treatment period, ECGs must also be performed at 3 h post-dose. In 
case of need of concomitant treatment with a QT-prolonging drug with known risk of 
Torsades de Pointes, additional ECGs will be performed according to the guidance 
provided in Appendix 3. 
At Visit 3 (Day 1) and on the day of re-initiation of study drug when post-dose monitoring 
is required [see Section 5.1.10], ECGs must be performed at pre-dose, and hourly (+/− 15 
min) thereafter for a minimum of 4 h and up to 12 h post-dose. Subjects may be discharged 
from the cardiac monitoring if they meet the discharge criteria before 12 h post-dose but 
no sooner than the (report of) ECG at 4 h post-dose has been evaluated by the first-dose 
administrator [see Section 5.1.11]. If the subject does not meet the defined discharge 
criteria at 12 h post-dose, the subject will be permanently discontinued from the study drug 
but will continue to be monitored, and additional ECG measurements will be performed 
until changes in ECG variables are no longer clinically relevant [i.e., discharge criteria are 
met; see Section 5.1.11], or until medically indicated. 
On Day 1 and on the first day of re-initiation of study drug when post-dose monitoring is 
required, significant findings, which in view of the first-dose administrator meet the 
definition of a (non-serious) AE, have an onset after the study drug intake, and are resolved 
at the time of discharge of the subject from cardiac monitoring, must be recorded directly 
on the AE page of the eCRF by the first-dose administrator. These AEs will not be visible

to any of the blinded study personnel at the study site. All other significant findings on Day 
1 or on the first day of re-initiation of study drug when post-dose monitoring is required 
that are serious or unresolved at the time of discharge of the subject from cardiac 
monitoring or with an onset on any other day, which in her/his view meet the definition of 
an AE, must be reported to the principal investigator / treating neurologist who will record 
these events on the AE page of the eCRF. 
7.3.2 Blood pressure 
BP measurements include SBP and DBP. 
BP monitoring will be performed using the same type of device throughout the study on 
the same arm with the subject in a fully rested supine position after the subject has been 
allowed to rest for a minimum of 5 min prior to the measurement. At all assessments 
(except post-dose assessments after first dose on Day 1 or at re-initiation), SBP and DBP 
will be measured twice (i.e., two SBP measurements and two DBP measurements). 
The two obtained measurements (i.e., two SBP measurements and two DBP 
measurements) and the position and arm used are to be recorded in the eCRF. The means 
of the two obtained measurements will calculated by the eCRF. Post-dose assessments at 
Visit 3 (Day 1) and at visits for re-initiation of study drug when post-dose monitoring is 
required will only be measured once at each timepoint. This single obtained SBP 
measurement is to be used for determining discharge criteria on Day 1 and on day of 
re-initiation of study drug when post-dose monitoring is required.  
At Visit 3 (Day 1) and at visits for re-initiation of study drug when post-dose monitoring 
will be required, the assessment of vital signs will be performed under the responsibility of 
the first-dose administrator who will also evaluate and interpret these assessments. At all 
other visits, it will be performed under the responsibility of the treating neurologist or the 
first-dose administrator, depending on the site setting [see Section 3.3.2 and Section 3.3.4].  
On Day 1 and on the first day of re-initiation of study drug when post-dose monitoring is 
required, significant findings, which in view of the first-dose administrator meet the 
definition of an AE, have an onset after the study drug intake, and are resolved at the time 
of discharge of the subject, must be recorded directly on the AE page of the eCRF by the 
first-dose administrator. These AEs will not be visible to any of the blinded study personnel 
at the study site. All other significant findings on Day 1 or on the first day of re-initiation 
of study drug when post-dose monitoring is required that are unresolved at the time of 
discharge of the subject from cardiac monitoring or with an onset on any other day which 
in her/his view meet the definition of an AEs must be reported to the principal investigator 
/ treating neurologist who will record these events on the AE page of the eCRF. 
BP measurements will be performed at all scheduled study visits. In addition, unscheduled 
BP measurements may be performed at any time during the study (Visits U1, U2, etc.). At

Visit 3 (Day 1) and on days of re-initiation of study drug when post-dose monitoring is 
required, [see Section 5.1.10], SBP and DBP will be measured at pre-dose and hourly (+/− 
15 min) thereafter for a minimum of 4 h and up to 12 h post-dose. Subjects may be 
discharged from cardiac monitoring if they meet the discharge criteria before 12 h post-
dose but no sooner than 4 h post-dose [see Section 5.1.11]. If the subject does not meet the 
defined discharge criteria at 12 h post-dose, the subject will be permanently discontinued 
from the study drug but will continue the cardiac monitoring, and additional BP 
measurements will be performed until changes are no longer clinically relevant [i.e., 
discharge criteria are met; see Section 5.1.11], or until medically indicated. 
7.3.3 Body temperature 
Body temperature will be assessed at all scheduled study visits. Body temperature will also 
be assessed at unscheduled visits for relapses (Visits R1, R2, etc.). In addition, body 
temperature measurements may be performed at any time during the study, as part of 
unscheduled visits (Visits U1, U2, etc.). 
All body temperature assessments will be documented in the source documents of the 
subject. All body temperature values should also be recorded in the eCRF as normal or 
abnormal. If an abnormality is found, it should be specified on the corresponding eCRF 
page. Clinically relevant findings meeting the definition of an AE (new AE, or worsening 
of previously existing condition) [see Section 10.1], must be recorded on the AE page of 
the eCRF. 
7.3.4 Pulse rate 
Pulse rate will be assessed at unscheduled visits for relapses (Visits R1, R2, etc.). If the 
visit for relapse corresponds to a visit when 12-lead ECG is performed, pulse rate 
assessment may be omitted. Pulse rate may also be assessed at any time during the study, 
as part of unscheduled visits (Visits U1, U2, etc.) when 12-lead ECG may not be 
performed. 
All pulse rate examinations will be documented in the source documents of the subject. All 
pulse rates should also be recorded in the eCRF as normal or abnormal. If an abnormality 
is found, it should be specified on the corresponding eCRF page. Clinically relevant 
findings meeting the definition of an AE (new AE, or worsening of previously existing 
condition) [see Section 10.1], must be recorded on the AE page of the eCRF. 
7.3.5 Spirometry 
Spirometry tests will be performed at Visits 2, 5, 6, 10, 14, 15, and 16 (Baseline, Week 4, 
Week 12, Week 60, EOT, FU1 and FU2). If applicable, spirometry tests will also be 
performed at Visit 14A in the PTOP. In addition, unscheduled spirometry will have to be 
conducted in the event of persistent respiratory symptoms (e.g., dyspnea).

Prior to randomization, spirometry can be performed at Visit 2 or at any time during the 
pre-randomization period. Spirometry at Visits 5, 6, 10, 15, and 16 (Week 4, 12, 60, FU1, 
and FU2) may be performed up to 7 days prior to or after the visit date. At Visit 14 (EOT), 
spirometry may be performed up to 7 days prior to the visit date but no later than 7 days 
after the discontinuation of study drug. It is highly recommended that all spirometry 
assessments are performed in the morning, preferably between 06:00 and 10:00, at 
approximately the same time to avoid diurnal variation. When applicable, it is also highly 
recommended that all spirometry assessments are performed prior to study drug intake. 
Spirometry testing will consist of assessing FVC and FEV1. Further indices, part of the 
collected flow-volume curves, may be explored and/or used for spirometry quality control 
measures. The following flow-volume curve indices will be collected at each timepoint: 
FEV1; FVC; the instantaneous forced expiratory flow (FEF) at 25%, 50% and 75% of the 
FVC (FEF25%, FEF50%, FEF75%, respectively); the mean FEF between 25% and 75% of the 
FVC (FEF25–75%); and the peak exploratory flow.  
Spirometry tests will be conducted according to the ATS / ERS guidelines [Miller 2005a, 
Miller 2005b]. A central vendor will provide equipment and detailed instructions for use, 
calibration and validation of spirometers. The provided spirometer must fulfill the technical 
requirements and recommendations for range and accuracy for forced expiratory 
maneuvers from the ATS/ERS guidelines [Miller 2005b]. The pulmonary function facility 
will ensure that the spirometer is functioning properly and is calibrated according to 
manufacturer instruction and ATS/ERS guidelines. A copy of the calibrations of the day of 
test must be stored as source documents in the subject charts at each subject visit, and a log 
of calibration results must be maintained at the site.  
Spirometry testing will be performed by a PFT technician, respiratory therapist or expert, 
or an equally experienced person according to the ATS/ERS guidelines (e.g., for the US, a 
registered pulmonary function technologist and/or a registered respiratory therapist). 
To the extent logistically feasible, attempts should be made to have the same tester 
throughout the study for a subject. Back-up testers (PFT technician, respiratory therapist, 
or expert or an equally experienced person according to the ATS/ERS guidelines may 
conduct spirometry if the primary tester is not available. All PFT technicians or other 
experienced persons participating in the studies will be trained on the specific requirements 
for the studies and have refreshment on ATS/ERS recommendations before study start and 
when compliance issues are identified. In addition, a specific PFT manual will describe the 
procedures to be implemented by the pulmonary function facility at each investigational 
site, in order to maintain high quality standards and in order to ensure the validity of the 
data collected.  
Subjects must refrain from taking short-acting-beta-agonists (e.g., salbutamol) for 6 h and 
long-acting-beta-agonists for 24 h prior to spirometry testing. If taken, the test should be

rescheduled. To perform the spirometry test, subjects will be rested for a minimum of 5 min 
prior to start. Sufficient forced expiratory maneuvers (up to a maximum of eight) will be 
performed to produce a minimum of three technically acceptable and repeatable traces 
(according to ATS/ERS guideline criteria; see PFT manual). The best (largest) FEV1 and 
FVC values from the three acceptable and repeatable tests will serve for the calculation of 
% of predicted values and used for the endpoint derivations. These values may come from 
separate maneuvers. The FEV1 and FVC measures obtained at Visit 2 (Baseline) and 
selected as described above will be used as the study baseline. 
All recorded spirometry values will be transmitted to the centralized reader, and will be 
reviewed by independent readers. Quality of the assessments will be evaluated for 
compliance with ATS/ERS criteria, and queries may be sent to the sites for clarification. If 
quality issues are identified, additional training will be provided. PFT values that trigger 
study drug discontinuation will be flagged. Clinically relevant findings meeting the 
definition of an AE (new AE, or worsening of previously existing condition) 
[see Section 10.1]), must be recorded on the AE page of the eCRF. Assessments may need 
to be repeated if results are of poor quality and/or inconclusive as per central reading. 
Predicted normal values for FVC and FEV1 will be used to determine exclusion criteria. 
Predicted normal values will be adjusted for subjects from ethnic groups other than 
white/Caucasian. The formulas for the calculation of the predicted normal values for FEV1 
and FVC and the ethnic group adjustments used in this study are those of the European 
Community for Coal and Steel [Quanjer 1993] (see details in PFTs manual). 
Spirometry conduct, documentation, performance, training details (of the responsible PFT 
site personnel), and quality control procedures are described in the PFT manual. 
7.3.6 DLCO sub-study 
DLCO will be assessed in a subset of approximately 400 subjects at selected sites with 
appropriate and established PFT expertise. Only subjects who consent under a separate 
informed consent for DLCO will participate in the sub-study. The assessment will be 
conducted at Visits 2, 5, 6, 10, 14, 15, and 16 (Baseline, Week 4, Week 12, Week 60, EOT, 
FU1, and FU2). If applicable, DLCO tests will also be performed at Visit 14A in the PTOP. 
In addition, unscheduled DLCO tests may be performed at any time during the study (Visits 
U1, U2, etc.).  
Prior to randomization, DLCO can be performed at Visit 2 or at any time during the 
pre-randomization period. DLCO at Visit 5, 6, 10, 15, and 16 (Week 4, 12, 60, FU1, and 
FU2) may be performed up to 7 days prior to or after the visit date. At Visit 14 (EOT), 
DLCO may be performed up to 7 days prior to the visit date but no later than 7 days after 
the discontinuation of study drug.

DLCO tests will be performed by a PFT technician, respiratory therapist or expert or an 
equally experienced person according to the ATS/ERS guidelines [Miller 2005a]. DLCO 
results will be reviewed by a pulmonologist or a physician adequately trained in 
pulmonology. All PFT technicians or other experienced participating persons will be 
trained on the specific requirements and have refreshment on ATS/ERS recommendations 
before starting on the study and will receive additional training when non-compliance 
issues are identified.  
DLCO tests will be conducted according to the ATS/ERS guidelines and will be assessed 
by the single breath method [Macintyre 2005]. DLCO efforts, up to a maximum of five, will 
be performed to produce at least two technically acceptable and repeatable traces 
(according to ATS/ERS guideline criteria; see DLCO manual). There must be a minimal 
interval of at least 4 min between each effort performed. Data from all DLCO efforts 
collected during a session will be captured in the eCRF.  
All recorded DLCO values will be transmitted to a centralized reader and will be reviewed 
by independent readers. Quality of the assessments will be evaluated for compliance with 
ATS/ERS criteria and will be reported in the eCRF; queries may be sent to the sites for 
clarification. If quality issues are identified, additional training will be provided to the site. 
Assessments may need to be repeated if results are of poor quality and/or inconclusive as 
per central reading facility. The selection of the DLCO values to be used for the main 
endpoint derivations will be validated by the independent readers. The mean of two best 
within-session DLCO efforts that meet the acceptability criteria according to the 
independent reader assessment will be selected and calculated by the sponsor as the value 
for this session. If only one acceptable effort is achieved, this will be selected by the 
sponsor for this session. If no acceptable effort is achieved, the effort with the highest 
inspiratory vital capacity will be selected by the sponsor for this session. For the analysis, 
the results will be corrected for Hb concentration and reported at a standard Hb 
concentration using the Cotes method [Macintyre 2005] (calculated by the sponsor in the 
database using the Hb value from the central laboratory).  
The sites participating in the sub-study will use their own DLCO gas analyzer and must 
ensure it is calibrated and working properly. The gas analyzer will need to fulfill the 
technical requirements and recommendations for range and accuracy for DLCO assessment 
from the ATS/ERS guidelines [Macintyre 2005]. A copy of the calibrations of the day of a 
test must be stored as source documents in the subject charts at each subject visit, and a log 
of calibration results must be maintained at the site. In addition, frequent testing involving 
the same healthy subject control (biological quality check) or a DLCO simulator will ensure 
continuous monitoring of the gas analyzer measurement accuracy over time (see details in 
PFT manual).

If clinically significant alterations in DLCO variables indicating a pulmonary condition that 
could result in increased risk for the subject are observed, she/he may be prematurely 
discontinued from the study drug at the discretion of the investigator. Clinically relevant 
findings meeting the definition of an AE (new AE, or worsening of previously existing 
condition) [see Section 10.1], must be recorded on the AE page of the eCRF. 
A specific PFT manual will describe the procedures to be implemented by the pulmonary 
function facility at each investigational site in order to maintain high quality standards and 
to ensure validity of the data collected. To the extent logistically feasible, all within-subject 
DLCO should preferably be done by the same tester. A back-up tester (PFT technician, 
respiratory therapist, or expert or an equally experienced person according to the ATS/ERS 
guidelines [Miller 2005a]) may conduct DLCO if the primary tester is not available. This 
back-up tester must be trained on the specific requirements and have had refreshment on 
ATS/ERS recommendations before starting on the study. DLCO conduct, documentation, 
performance, training details (of the responsible PFT site personnel), and quality control 
procedures are described in the PFT manual. 
7.3.7 Chest X-ray 
CXR will be performed at Visit 1 (Screening) or at any time during the pre-randomization 
period and assessed by the local radiologist in order to exclude any subject with findings 
suggestive of active or latent TB. Any CXR performed within 90 days prior to screening 
can be used; if available, there is no need to repeat CXR at Screening. In case of 
re-screening, CXR does not need to be repeated if it was performed within 90 days prior to 
the date of re-screening.  
CXR will be repeated at the EOT visit in all subjects to characterize any pulmonary 
structural changes occurring during treatment. In case of premature discontinuation, the 
CXR at EOT does not need to be performed if the EOT visit occurs within less than 
24 weeks of the pre-randomization CXR. All examinations will be documented in the 
source documents of the subject. Examinations should also be recorded in the eCRF as 
normal or abnormal. If an abnormality is found, it should be specified on the corresponding 
eCRF page. Clinically relevant findings meeting the definition of an AE (new AE, or 
worsening of previously existing condition) [see Section 10.1] must be recorded on the AE 
page of the eCRF. Study participants, who experience clinically significant changes in 
CXR will be followed-up until establishing the final diagnosis and managed as per local 
medical practice. Other diagnostic procedures may be performed as a FU assessment 
according to local standard procedures when considered necessary by the investigator.

the central laboratory [see Section 7.3.14], and transferred to the eCRF database.  
Only subjects with a negative test at Screening and without CXR findings [see 
Section 7.3.7] at Screening or within the previous 90 days suggestive of active or latent 
tuberculosis can be included in the study. If the test result is positive, subjects must not be 
included in the study, except if there is documentation that the subject has received 
adequate treatment for TB previously. If the test result is inconclusive (invalid, 
indeterminate, or borderline), the test may be repeated once and a negative result must be 
obtained prior to randomization in order to include the subject. If the result of the repeated 
test is again inconclusive (invalid, indeterminate, or borderline), subjects must not be 
included in the study. 
Details on the performance of the test for TB will be provided in the specific central 
laboratory manual. 
7.3.9 Ophthalmologic assessments 
Ophthalmologic assessments will be performed by an ophthalmologist at Visits 1 
(Screening), 6 (Week 12), 7 (Week 24), 10 (Week 60), and 14 (EOT). Testing at Visit 1 
can be performed at any time during the pre-randomization period. Testing at Visits 6, 7, 
10 (Weeks 12, 24, and 60) may be performed up to 7 days prior to or after the visit date. 
At Visit 14 (EOT), testing may be performed up to 7 days prior to the visit date but no later 
than 7 days after the discontinuation of study drug. In addition, unscheduled 
ophthalmological examination will be done in the event of visual symptoms or findings 
suggestive of active uveitis [see Section 5.1.13.7].  
The safety ophthalmological assessment includes previous eye history and ophthalmic 
condition, any new or current ophthalmological symptoms, assessment of best corrected 
visual acuity (ETDRS charts), measurement of ocular pressure with Goldmann applanation 
tonometry (recommended, if not available other tonometry methods are allowed), slitlamp 
examination of the anterior segment, and dilated indirect funduscopy. Additionally, the 
safety ophthalmological assessment will include fluorescence angiography in case of 
suspicion of active uveitis at Screening or during a scheduled ophthalmological assessment 
(unless contra-indicated according to the ophthalmologist) [see Section 5.1.13.7]. While 
the visual acuity and ocular pressure measurement themselves may be performed by a 
delegate (e.g., technician, optometrician), the review and interpretation must be performed 
by the ophthalmologist. Conduct, review, and interpretation of all other ophthalmological 
exams must be performed by the ophthalmologist. Fluorescence angiography (if

applicable) may be performed by a delegate (e.g., technician, optometrician) but always in 
the presence of the ophthalmologist who will review and interpret the results.  
The purpose of the assessment prior to randomization is to exclude subjects with macular 
edema or diabetic retinopathy from the study, and to document a baseline assessment. All 
ophthalmological examinations will be documented in the source documents of the subject. 
All parameters assessed at the ophthalmological examination should also be recorded in 
the eCRF as normal or abnormal. If an abnormality is found on any of the assessed 
parameters, it should be specified on the corresponding eCRF page. Clinically relevant 
findings meeting the definition of an AE (new AE, or worsening of previously existing 
condition) [see Section 10.1], must be recorded on the AE page of the eCRF. 
7.3.10 Optical Coherence Tomography 
OCT will be assessed at Visits 1 (Screening), 6 (Week 12), 7 (Week 24), 10 (Week 60), 
and 14 (EOT). Testing at Visit 1 can be performed at any time during the 
pre-randomization period. Testing at Visits 6 and 10 (Week 12 and 60) may be performed 
up to 7 days prior to or after the visit date. At Visit 14 (EOT), testing may be performed up 
to 7 days prior to the visit date but no later than 7 days after the discontinuation of study 
drug. In addition, unscheduled OCT examination will have to be assessed in the event of 
visual symptoms or findings suggestive of macular edema according to the 
ophthalmologist’s decision, or in case of active uveitis diagnosed during the study 
[see Section 5.1.13.7]. While the OCT exam may be performed by a delegate 
(e.g., technician, optometrician), the review and interpretation must be performed by the 
ophthalmologist.  
The purpose of the assessment prior to randomization is to exclude subjects with macular 
edema or diabetic retinopathy from the study, and to document a baseline assessment. The 
site will use the OCT device available locally and must ensure it is working properly. To 
the extent that is logistically feasible, the same OCT machine is to be used for each 
individual subject throughout the study.  
All examinations will be documented in the source documents of the subject. OCT 
examination should also be recorded in the eCRF as normal or abnormal. If an abnormality 
is found, it should be specified on the corresponding eCRF page. Clinically relevant 
findings meeting the definition of an AE (new AE, or worsening of previously existing 
condition) [see Section 10.1], must be recorded on the AE page of the eCRF. 
The OSB will receive all information related to suspected cases of macular edema and will 
perform a central, blinded review of OCT results and subject data of suspected cases of 
macular edema.

7.3.11 Weight and height 
Body weight will be measured at Visits 1 (Screening), 10 (Week 60) and 14 (EOT). 
In addition, unscheduled body weight measurement may be performed at any time during 
the study (Visits U1, U2, etc.). Body height is only measured at Visit 1 (Screening). Data 
will be collected in the eCRF. 
7.3.12 Physical examination 
Physical examination is performed by the principal investigator or treating neurologist at 
Visits 1 (Screening), 2 (Baseline), 5, 6, 7, 10, and 12 (Weeks 4, 12, 24, 60, and 84), 
14 (EOT), and at unscheduled visits due to relapses (R1, R2, etc.). If applicable, physical 
examination will also be performed at Visits 10A and 14A in the PTOP. In addition, 
unscheduled physical examination may be performed at any time during the study (Visits 
U1, U2, etc.) if deemed necessary by the investigator.  
Physical examination includes the examination of the general appearance, head, eyes, ears, 
nose, throat, neck, heart, lungs, abdomen, lymph nodes, extremities, skin, neurological, and 
musculoskeletal functions. Other exams will be performed if indicated, based on medical 
history and/or symptoms. 
Information for all physical examinations must be included in the source documentation at 
the study site. The observations should be reported by body system in the eCRF as normal 
or abnormal. If an abnormality is found, it should be specified on the corresponding eCRF 
page, describing the signs related to the abnormality (e.g., systolic murmur). Clinically 
relevant findings meeting the definition of an AE (new AE, or worsening of previously 
existing condition) must be recorded on the AE page of the eCRF. 
Note: 
The standardized neurological evaluation based on EDSS and FS scores conducted by the 
efficacy assessor [see Section 7.2.1] does not obviate the requirement for the examination 
of the neurological function as part of the physical examination by the treating neurologist. 
7.3.13 Dermatological examination 
A complete skin examination will be performed by a dermatologist at Visits 2 (Baseline), 
10 (Week 60), and 14 (EOT). If applicable, dermatological examination will also be 
performed at Visits 10A and 14A in the PTOP. In addition, unscheduled complete skin 
examination may be performed by the dermatologist at any time during the study 
(Visits U1, U2, etc.). The purpose of the skin examination prior to randomization is to 
record the pre-existing lesions, exclude subjects with suspicious skin lesions 
(pre-cancerous, cancerous) from the study, and to document a baseline assessment. In case 
of re-screening, skin examination does not need to be repeated if skin examination from 
initial screening was performed within 90 days prior to the date of re-screening.

In the event of findings of suspicious or pre-cancerous or cancerous skin disorders observed 
at any visit during the study, the dermatologist will conduct further examination, as per 
local standard practice, including the taking of skin biopsies if required to rule out or 
confirm a diagnosis.  
All examinations will be documented in the source documents of the subject. 
Dermatological examination should be recorded in the eCRF as normal or abnormal. If an 
abnormality is found, it should be specified on the corresponding eCRF page. Clinically 
relevant findings meeting the definition of an AE (new AE, or worsening of previously 
existing condition) [see Section 10.1] will be recorded accordingly on the AE page of the 
eCRF.  
7.3.14 Laboratory assessments 
7.3.14.1 Type of laboratory 
A central laboratory (see central laboratory manual for contact details) will be used for all 
protocol-mandated laboratory tests, including re-tests due to laboratory abnormalities and 
laboratory tests performed at unscheduled visits. Central laboratory data will be 
automatically transferred from the central laboratory database to Actelion’s clinical 
database. 
Under specific circumstances (e.g., subject lives far away from the site and cannot return 
every 2 weeks during the first 24 weeks), laboratory samples could be drawn in a local 
laboratory close to where the subject lives and analyzed at the central laboratory. In such 
circumstances, the local laboratory must be provided with the central laboratory kits, which 
must be used for blood collection. The blood samples collected locally will be shipped by 
the local laboratory to the central laboratory for analysis. Such a local laboratory shall be 
identified as soon as possible, but no later than upon enrollment of the subject in the study.  
Local laboratory results will only be collected in exceptional cases (e.g., subject is 
hospitalized in a different hospital from the study center due to a medical emergency). In 
cases where a local laboratory is used for the collection and analysis of blood samples, the 
local laboratory results (with the corresponding normal ranges) will be entered into the 
clinical database via dedicated eCRF pages. In all cases, testing of total lymphocytes count 
at a local laboratory is not to be assessed and collected unless deemed absolutely necessary 
by the investigator for maintaining safety of the subject. 
If a central laboratory sample is lost, has deteriorated or cannot be analyzed for whatever 
reason, the investigator may collect an additional sample as soon as possible for retest 
analysis if still clinically relevant.

The central laboratory will provide all laboratory results by fax or normal mail to the site 
with the exception of the results of the total WBC count, total lymphocyte count, and 
teriflunomide plasma concentration.  
• Total WBC count and total lymphocyte count: WBC and lymphocyte count results 
during treatment period will not be communicated to the site unless a total lymphocyte 
count < 0.2 × 109/L is recorded by the central laboratory. In this event, an alert 
containing the total lymphocyte count result will be sent to the principal investigator / 
treating neurologist and the sponsor [see Section 5.1.13].  
• Teriflunomide plasma concentration:  
− For subjects not entering the AC-058B303 extension study: Teriflunomide 
plasma concentration may be assessed if needed to determine if contraception 
can be discontinued [see Section 5.1.14.4]. Teriflunomide plasma concentration 
can also be assessed for any subjects not entering the extension study if deemed 
necessary for the subject’s safety, at the investigator’s discretion. Sites will 
receive notification if teriflunomide plasma level is < 0.02 mg/L. Sites will also 
receive notification if teriflunomide plasma level is ≥ 0.02 mg/L; In this event, 
the principal investigator / treating neurologist will decide whether the 
accelerated elimination procedure should be repeated (e.g., if rapid elimination 
is needed, such as a wish to become pregnant or father a child 
[see Section 5.1.14] or whether physiological elimination alone is warranted). 
− For subjects who enter the AC-058B303 extension study: The timing of 
teriflunomide test and procedures are described in the AC-058B303 study 
protocol (separate protocol).  
• A WBC count > 20 × 109/L or a lymphocyte count > 8.0 × 109/L is recorded by the 
central laboratory [see Appendix 6]. In this event, an alert containing the total WBC or 
lymphocyte count result (as applicable) will be sent to the principal investigator and 
the sponsor. 
• WBC and total lymphocyte counts measured at Visit 1 (Screening), 2 (Baseline), and 
any of the visits in the PTOP (if applicable) will be visible to the treating neurologist. 
All laboratory reports must be signed and dated by the principal investigator or delegate 
within 5 calendar days of receipt and filed with the source documentation. The 
investigator/delegate must indicate on the laboratory report whether abnormal values are 
considered clinically relevant or not. Clinically relevant laboratory findings meeting the 
definition of an AE [see Section 10.1] must be reported as an AE or SAE as appropriate, 
and must be followed until the value returns to within the normal range or is stable, or until

the change is no longer clinically relevant. Further laboratory analyses should be performed 
as indicated and according to the judgment of the investigator. 
Details about the collection, sampling, storage, shipment procedures, and reporting of 
results and abnormal findings can be found in the laboratory manual. 
7.3.14.2 Laboratory tests 
Blood samples will be drawn preferably in a fasted condition and, when applicable, before 
the morning administration of study medication at Visit 1 (Screening), Visit 2 (Baseline), 
Visits 4 to 13 (Week 2, 4, 12 and every 12 weeks thereafter), Visit 14 (EOT), Visit 15 
(FU1), and Visit 16 (FU2) and, if applicable, at the corresponding visits in the PTOP (Visits 
7A, 10A, 12A, and 14A). In addition, ALT, AST, INR, alkaline phosphatase (AP), and 
total bilirubin will be assessed on a bi-weekly basis until Week 24 (i.e., at Week 6, 8, 
10, 14, 16, 18, 20, and 22). Furthermore, total WBC and total lymphocyte counts will 
be assessed on a 4-weekly basis until Week 24 (i.e., at Week 8, 16, and 20). Unscheduled 
laboratory tests may be performed at any time during the study (Visits U1, U2, etc.). 
Urinalysis will be assessed using dipsticks at Visit 1 (Screening), Visits 5, 6, 7, 10, and 12 
(Week 4, 12, 24, 60, and 84), Visit 14 (EOT), and Visit 15 (FU1) and, if applicable, at the 
corresponding visits in the PTOP (Visits 7A, 10A, 12A, and 14A). In addition, unscheduled 
urinalysis may be performed at any time during the study (Visits U1, U2, etc.). 
Laboratory assessments at Visit 1 must be performed a minimum of 7 days before the 
laboratory assessment at Visit 2. 
If a laboratory sample cannot be evaluated (e.g., is lost or deteriorated), an additional 
sample may need to be taken if deemed necessary by the investigator.

confirmatory blood sample for testing of Hepatitis C viral RNA. 
Biomarkers and additional analyses in the event of infections  
• A serum sample will be taken at Visit 2 (Baseline) to be stored at the central laboratory 
for potential retrospective analyses of viral serology titers in the event of infections 
(e.g., suspected opportunistic infection) during the study or for analysis of biomarkers. 
Additional analyses in the event of a vaccination with non-live vaccines 
• Subjects receiving non-live vaccination while on study treatment will have 5 mL of 
blood drawn prior to and ≥ 3 weeks after vaccination in order to explore changes in 
vaccine-specific antibody titers from pre- to post-vaccination. Samples are to be stored 
at the central laboratory to be analyzed at the end of the study.

after last study drug intake on a 4-weekly basis until 6 weeks after the first of two tests 
showing teriflunomide plasma level < 0.02 mg/L (results to be communicated by telephone 
call to the principal investigator / treating neurologist). 
In order for WOCBP to be randomized in the study, they must have a confirmed negative 
serum pregnancy test at Visit 1 and a second confirmed negative urine pregnancy test prior 
to randomization. The two tests must be performed a minimum of 3 weeks apart.  
Serum pregnancy testing results will be automatically transferred from the central 
laboratory database to Actelion’s clinical database. Urine pregnancy testing results will be 
recorded in the eCRF. In case of pregnancy, a Pregnancy Form must be completed [see 
Section 10.3]. 
Urinalysis 
• pH 
• Glucose 
• Proteins 
• Blood 
• Leukocytes 
• Bilirubin, urobilinogen 
Urine dipsticks provided by the central laboratory will be used to perform the urinalysis. 
The test should be performed and analyzed at the site. The results must be documented in 
the source documents / subject charts and should be recorded in the eCRF as normal or 
abnormal. If an abnormality is found, it should be specified on the corresponding eCRF 
page and the results for the abnormal parameter will be reported in the eCRF. Clinically 
relevant findings meeting the definition of an AE (new AE, or worsening of previously 
existing condition) [see Section 10.1] will be recorded accordingly on the AE page of the 
eCRF. 
Evaluation of teriflunomide elimination:  
The testing of teriflunomide plasma concentration may only be conducted for women of 
childbearing potential and fertile male subjects, if needed, to confirm that contraception 
can be discontinued.  
For subjects not entering the AC-058B303 study, teriflunomide plasma levels will be 
determined by the central laboratory if necessary to determine if contraception can be 
discontinued. Teriflunomide plasma concentration can also be assessed for any subjects 
not entering the extension study if deemed necessary for the subject’s safety, at the 
investigator’s discretion. The testing should not occur before 20 weeks after last drug

is described in the separate AC-058B303 study protocol. 
7.4 Electronic self-rated version of the Columbia-Suicide Severity Rating 
Scale (eC-SSRS) 
The electronic self-rated version of the eC-SSRS is used to reliably and consistently 
monitor subjects for suicidal ideation and behavior during the study.  
The eC-SSRS assesses lifetime suicidality during an initial baseline evaluation  
(Visit 2-Baseline), and then prospectively monitors ideations and behaviors at subsequent 
follow-up assessments (Visit 10-Week 60 and Visit 14-EOT). At each visit, the treating 
neurologist will review the responses provided by the subject and assess the findings. The 
eC-SSRS is a fully structured clinical interview designed and developed for computer 
administration. Subjects will be asked to respond to standardized clinical questions aiming 
at measuring the severity of suicidal ideation (rated on a 5-point ordinal scale), the levels 
of suicidal behavior, and the category self-injurious behavior without suicidal intent. Any 
subjects who reaches an eC-SSRS suicidal ideation score of 4 or above, or who responds 
“yes” on the eC-SSRS suicidal behavior item must be referred to an appropriate health 
professional who should make a decision on the management of the suicidal symptoms and 
recommend whether or not the subject should continue the treatment with the study drug. 
It is recommended that the eC-SSRS is completed prior to any clinical assessments, after 
the PGI-S of Fatigue, WPAI:MS and SF-36v2™ have been completed. Preferably, subjects 
would complete the eC-SSRS while waiting for their appointment before any interaction 
with health care providers. 
A sample of the eC-SSRS (in English) is provided as Appendix 16. The scale will be 
administered using a telephone-based system. The clinical site will provide a telephone to 
be used during above mentioned visits and the subject will respond to the questions with 
the telephone keypad. The data will be collected by the vendor who will send the results to 
Actelion. 
Actelion has been granted a license agreement for the use of the eC-SSRS.

7.5 Quality of life assessments 
7.5.1 36-Item Short Form Health Survey v2 (SF-36v2™) 
The SF-36v2™ Questionnaire (SF-36v2™ Health Survey© 1996, 2000 by Medical 
Outcomes Trust and Quality Metric Incorporated) is used to assess the subject’s quality of 
life. The SF-36v2™ will be completed by the subject at Visit 2 (Baseline), at Visits 6, 7, 
10, 12 (Weeks 12, 24, 60, and 84), and 14 (EOT) and at unscheduled visits due to relapses 
(R1, R2,etc.). 
In the SF-36v2TM Questionnaire, subjects are instructed to rate their health and capacity to 
perform activities of daily living in eight domains including physical functioning, physical 
role limitations, bodily pain, general health, vitality, social functioning, emotional role 
limitations, and mental health during the last 4 weeks. Raw domain scores are determined 
and transformed to a 0–100 scale as described in the SF-36v2™ manual [Maruish 2011]. 
Individual domain scores are used to determine the physical and mental component 
summary scores as described in the SF-36v2™ manual [Maruish 2011]. 
It is recommended that the SF-36v2™ Questionnaire is completed prior to any clinical 
assessments, after the PGI-S of Fatigue and WPAI:MS have been completed. Preferably, 
subjects would complete the SF-36v2™ while waiting for their appointment before any 
interaction with health care providers to avoid any potential bias in their responses. 
The SF-36v2™ with a 4-week recall period will be used. A sample of the SF-36v2™ 
(in English) is provided as Appendix 11. The questionnaire will be administered in an 
electronic format. The data from the electronic device will be collected by the vendor who 
will send the results to Actelion. 
Actelion has been granted a license agreement for the use of the SF-36v2™ questionnaire. 
The individual questionnaires will be completed only in countries for which validated 
translations are available. 
7.6 Pharmacoeconomic assessments 
7.6.1 Work Productivity and Activity Impairment Questionnaire: Multiple 
Sclerosis V2.0 
The WPAI:MS is a 6 question patient-reported quantitative assessment of the amount of 
absenteeism, presenteeism, work productivity loss and activity impairment attributable to 
MS during the previous 7 days.  
Actelion has adapted the specific health version of the WPAI version 2, which was 
developed by Reilly Associates for MS.  
The WPAI:MS will be completed by the subject at Visit 2 (Baseline), at Visits 6, 7, 10, 12 
(Weeks 12, 24, 60, and 84), and 14 (EOT).

WPAI:MS outcomes are expressed as impairment percentages, with higher numbers 
indicating greater impairment and less productivity, i.e., worse outcomes. 
It is recommended that the WPAI:MS Questionnaire is completed prior to any clinical 
assessments, after the PGI-S of Fatigue has been completed. Preferably, subjects would 
complete the WPAI:MS while waiting for their appointment before any interaction with 
health care providers to avoid any potential bias or impact of interventions in their 
responses. 
A sample of the WPAI:MS (in English) is provided as Appendix 10. The questionnaire 
will be administered in an electronic format. The data from the electronic device will be 
collected by the vendor who will send the results to Actelion. 
Actelion Pharmaceuticals has notified the developer about the use of the instrument in this 
study. No license is required for the administration of the instrument. The individual 
questionnaires will be completed only in countries for which validated translations are 
available. 
7.6.2 Health care resource utilization 
Health care resource utilization data, including number of intensive care unit (ICU) 
admissions for MS relapses and emergency medical facility visits for MS will be collected 
at Visits 4 to 13 (Weeks 2, 4, 12, 24, 36, 48, 60, 72, 84, and 96), and 14 (EOT) as well as 
at unscheduled visits due to relapse (R1, R2,…).  
Subjects will be asked to report any visits to emergency medical services facilities due to 
MS since the last study visit, and the dates will be captured in the eCRF. Hospitalization 
due to MS relapses will be captured in the eCRF including the length of stay and any 
admissions to ICU. 
7.7 Pharmacokinetic and pharmacodynamic assessments 
These assessments are done to investigate PD and PK effects of ponesimod. 
7.7.1 Pharmacokinetic assessments 
7.7.1.1 Timing for sampling 
PK samples will be collected during this study for all subjects, in order to provide 
information about study drug exposure in the target population. Blood samples will be 
collected pre-dose at Visits 6, 10 and 14 (EOT; Week 12, 60 and 108). Additionally, at 
Visits 3 and 6 (Day 1 and Week 12), PK samples will be drawn 3 h (+/− 15 min) post-dose.  
When possible, a PK sample will be collected for all subjects experiencing SAEs. In this 
event, the sample should be collected pre-dose, as early as possible after SAE onset, and 
no later than 7 days after the last dose of study drug.

7.7.1.2 Procedures for sampling 
Up to 3 mL of blood must be collected in tubes containing ethylenediaminetetraacetic acid. 
Immediately following collection of the required blood volume, the tubes must be slowly 
tilted backwards and forwards (no shaking) to bring the anti-coagulant into solution, and 
immediately cooled on ice. Within 30 min of collection, the tubes must be centrifuged at 
approximately 1500 g for 10 min at 2 to 8 °C. When a centrifuge that can be cooled is not 
available, the blood samples and the bucket of the centrifuge must be cooled on ice prior 
to centrifugation. The plasma must be transferred into one labeled opaque polypropylene 
tube to avoid carry-over of erythrocytes. All samples must be stored in an upright position 
≤ −20 °C (Freezer settings: intended temperature −25 °C; upper limit −20 °C). The exact 
time of collection of the blood sample must be entered in the eCRF, as well as the status of 
the subject (fed or fasted), and the time of last previous study drug intake. Blood samples 
for PK analysis must be drawn prior to study drug intake on the day of the visit (except at 
Visits 3 and 6, when a sample will be drawn 3 h post-dose).  
To prevent degradation of ponesimod in the plasma samples, exposure to light should be 
minimized. After centrifugation, plasma samples should be kept in the dark. 
Note: 
The 3-h PK sample on Day 1 or on the first day of re-initiation of study drug when 
post-dose monitoring is required should be taken by the first-dose administrator, the 
first-dose administrator nurse or another person not involved in the clinical care and 
management of the study subject. 
7.7.1.3 Labeling 
Details of the collection and shipment of the samples can be found in the laboratory manual 
provided to the investigator. The tubes and labels for the samples will be provided to the 
investigator and/or staff by the central laboratory. 
7.7.1.4 Bioanalysis 
The concentration of ponesimod in plasma will be determined by a validated liquid 
chromatography-tandem mass spectrometry assay by Idorsia PK analyses services. The 
lower limit of quantification is 1 ng/mL. 
Concentrations will be calculated by interpolation from a calibration curve. Quality control 
samples will be analyzed throughout the study. Their measured concentrations will be used 
to determine between-run and overall precision and accuracy of the analyses. 
If required, a selection of plasma PK samples may be analyzed by, or under the supervision 
of, the sponsor to assess the chiral inversion of ponesimod, and/or document the presence 
of circulating metabolites using a qualified research method.

The samples will be destroyed upon signature of the Clinical Study Report. 
7.7.2 Pharmacodynamic assessments 
The PD marker is total lymphocyte counts, which will be measured as part of the 
hematology tests [see Section 7.3.14].

SCHEDULE OF VISITS 
A tabulated summary of all visits and assessments described in the following sections is 
provided in Table 1, Table 2, and Table 3. The schedule of visit dates should be established 
at the time of screening. To the extent possible, subjects will be expected to adhere to the 
established visit schedule. 
The timepoint for every visit is defined taking as a reference Day 1 (Visit 3), which is the 
day of randomization.  
When scheduling the different assessments for a subject visit, the following should be taken 
in account:

• The subject must come to the clinic in a fasted condition for all visits and, when 
applicable, before the morning administration of study drug.  
• At Visit 3 (Day 1) and on the days of re-initiation of study drug when post-dose 
monitoring is required (if applicable), the assessments during the visits will be divided 
into two parts: before (pre-dose) and after (post-dose) the administration of the study 
drug, which will be taken at the site on the day of visits. 
• At other visits, ECGs, SBP/DBP, PFTs, blood drawings for hematology and 
biochemistry, along with all other assessments, are to be performed pre-dose.  
• When applicable, PK sampling is to be done pre-dose with an additional sample drawn 
3 h post-dose at Visits 3 (Day 1) and 6 (Week 12). On these visits, post-dose sampling 
must be drawn on the same day as pre-and post-dose ECGs and SBP/DBP are 
performed. 
• Resting time: 
− When the subject is to go to another department within the hospital for a specific 
test, sufficient time should be allowed for the subject to rest prior to the 
examination. 
− Sufficient resting time should be allowed between the walking assessments for 
MSFC and EDSS and other assessments (PFTs, ECGs, and BP). 
− Sufficient time between blood drawing and cardiac assessments (i.e., ECGs and/or 
BP measurement) is to be allowed.  
• Preferably, questionnaires will be completed by the subject in the morning prior to any 
other protocol mandated assessment and prior to any other discussion with the 
investigator or treating neurologist. Subjects will provide responses to the 
questionnaires while waiting for their appointment. Questionnaires should be 
completed in the following order: 
− PGI-S of Fatigue 
− WPAI:MS 
− SF-36v2™ 
− eC-SSRS 
To ensure compliance, at each visit the study personnel must remind WOCBP and fertile 
men to use the methods of contraception defined for this study. The reminders must be 
documented in the hospital chart.

It is permitted to re-screen subjects once if the reason for non-eligibility was transient (e.g., 
abnormal laboratory test, insufficient wash-out period of a forbidden medication), provided 
that documented authorization has been received from Actelion. Subjects who were not 
eligible because of a negative test for varicella-zoster antibodies may also be re-screened 
once after having been vaccinated. All pre-randomization assessments should then be 
repeated at the time of re-screening (with the exception of CXR and dermatological 
examination if performed within 90 days prior to the date of re-screening). 
Unscheduled visits may be performed at any time during the study. Depending on the 
reason for the unscheduled visit (e.g., relapse, AE, central laboratory re-test), appropriate 
assessments may be performed based on the judgment of the investigator and must be 
recorded in the eCRF. After an unscheduled visit, the regular scheduled study visits must 
continue according to the planned visit and assessment schedule. 
8.1 Pre-randomization period 
The pre-randomization period must take place within 45 days prior to randomization and 
include the Visit 1 (Screening), Visit 2 (Baseline) and the pre-dose assessments of Visit 3 
(Day 1).  
The start of screening occurs on the day the first screening assessment was performed (i.e., 
signature of informed consent). 
8.1.1 Visit 1 (Screening) 
Visit 1 will be performed from 45 to 11 days prior to randomization. The Visit 1 date is 
defined as the date of start of pre-randomization period (i.e., signature of the ICF). During 
this visit, subject informed consent will be obtained, and the assessments required for the 
determination of subject eligibility will be performed. These assessments may generally be 
performed on separate days within the pre-randomization period.  
Visit 1 includes: 
• After discussing the study with the investigator and after agreeing to study participation 
by signing the ICF, subjects will be assigned a subject number by the IRT provider. It 
is the responsibility of the investigator to obtain written informed consent prior to any 
screening assessment. The subject number will identify the subject throughout the 
study. In case of re-screening [see Section 8], the subject number assigned during the 
first screening procedure will be retained. 
• Review of MS diagnosis and McDonald 2010 criteria 
• Recording of demographics, medical history, smoking status, and disease 
characteristics 
• Recording of previous and concomitant medications [see Section 5.2]. 
• EDSS/FS (performed by the efficacy assessor)

• If the subject expresses any concern regarding her/his ability to swallow the medicine, 
she/he will be shown an example of a capsule to be used in the study and will be given 
the option to perform a swallowing test with a placebo capsule in order to test future 
compliance with study drug intake requirements. The test is to be done under the 
supervision of the site personnel. 
The principal investigator / treating neurologist must check all inclusion/exclusion criteria. 
The next visit (Visit 3) will only be scheduled if the subject meets all the eligibility criteria 
assessed at this time. Date of screen failure will be collected in the IRT system and in the 
eCRF; additionally, the reasons for screening failure are documented in the eCRF 
(screening information is collected for all screen failure subjects). 
8.2 Treatment period 
The treatment period consists of Visits 3 to 14 (Randomization Day 1, Week 2, 4, 12, and 
every 12 weeks thereafter until EOT/Week 108).  
8.2.1 Visit 3 – Randomization Day 1 
Visit 3 corresponds to the start of the treatment period and the date of randomization in the 
IRT system (Day 1 of the study). The ECGs (pre- and post-dose), BP (pre- and post-dose), 
and first-dose administration must be performed on the same day and define the date of the 
visit. The assessments during this visit will be divided into two parts: before (pre-dose) and 
after (post-dose) the administration of the study drug. 
8.2.1.1 Visit 3 – Day 1 – pre-dose assessment 
The principal investigator / treating neurologist must check all inclusion/exclusion criteria. 
Pre-dose assessments include:

• Recording of AEs/SAEs: all AEs/SAEs occurring after signing of the ICF are to be 
reported in the eCRF and on an SAE form, if applicable. 
8.2.1.2 Visit 3 – Day 1 – Randomization and post-dose assessment 
If eligible, the subject should be randomized in the study, and take the first dose of study 
drug. The subject must be monitored for up to 12 h post-dose. Starting at 4 h post-dose, the 
first-dose administrator must check whether the subject fulfills the discharge criteria from 
cardiac monitoring [see Section 5.1.11]. Subjects may be discharged from cardiac 
monitoring if they meet the discharge criteria before 12 h post-dose but no sooner than the 
(report of) 4 h post-dose ECG has been evaluated by the first-dose administrator 
[see Section 5.1.11]. 
Visit 3 randomization and post-dose assessment includes: 
• After confirmation of eligibility (i.e., verification of all entry criteria) by the 
investigator: 
− Randomization via IRT to obtain randomization and study treatment kit number 
− Dispensing of study treatment 
• SBP/DBP hourly (+/− 15 min) for up to 12 h post-dose with a minimum of 4 h post-
dose (under the responsibility of the first-dose administrator) 
• 12-lead ECG hourly (+/− 15 min) until the evaluation of the ECG performed at 4 h 
post-dose is available. For subjects not meeting the discharge criteria at 4 h post-dose, 
further ECGs will be performed every hour for up to 12 h post-dose until the discharge 
criteria are met (under the responsibility of the first-dose administrator) 
• PK sampling at 3 (+/− 15 min) h post-dose 
• Recording of AEs and SAEs (Note: On Day 1, significant findings that, in view of the 
first-dose administrator, meet the definition of an AE, have an onset after the study 
drug intake, and are resolved at the time of discharge of the subject from cardiac 
monitoring, must be recorded directly on the AE page of the eCRF by the first-dose 
administrator/delegate. These AEs will not be visible to any of the blinded study 
personnel at the study site.)  
• Remind WOCBP and fertile men to use the methods of contraception defined for this 
study. The reminders must be documented in the hospital chart. 
• Schedule an appointment for next visit and instruct subject to: 
− bring back all blister packs (used, partially used and unused blister packs) 
− come fasted to the site 
− not take study treatment on the day of study visit prior to coming to the site

− contact their principal investigator / treating neurologist at the clinical site 
immediately in the event of the appearance of any symptoms suggestive of an 
MS exacerbation. 
Subjects assigned to the ponesimod arm will need to gradually up-titrate from 2 mg to 
10 mg during Day 1 to 14. To maintain the blinding of the study, subjects assigned to the 
teriflunomide arm will mock up-titrate. As there is no site visit planned until Day 15, 
subjects will be instructed on how to perform the gradual up-titration / mock up-titration 
during Visit 3.  
The subject will be instructed to contact the site if she/he has any questions or problems.

8.2.10 Visit 14 – EOT Visit  
The EOT visit will take place at Week 108 (± 7 days) or earlier in case of premature 
discontinuation of study drug. In all cases, the EOT visit must take place after the last dose 
of study drug. Preferably, the visit and all assessments will take place 1 day after the last 
dose of study drug, but no later than 7 days after the last dose. Specific assessments (i.e., 
MRI, skin examination, CXR, spirometry, DLCO, OCT / Ophthalmological examination, 
hematology, blood chemistry, PK) may be conducted up to 7 days prior to last intake of 
study drug. If a study treatment interruption is transformed into a permanent premature 
discontinuation, the EOT visit should be done as soon as possible, but no later than 7 days 
after the decision to discontinue was made. The date of EDSS assessment, preferably 
corresponding to the date of registration of the visit in the IRT system, defines the date of 
the visit. The visit includes:

8.3 Post-treatment period 
8.3.1 Post-treatment safety follow-up period 
The safety FU period includes Visits 15 and 16 (FU1 and FU2). 
• For subjects who enter the extension study, the safety FU period lasts for 14 to 37 days 
after the last dose of study drug and consists of a safety FU visit (FU1) at 15 days 
(−1 day, +7 days) after the last dose of study drug, and for subjects who need to 
repeat/complete the accelerated elimination procedure of teriflunomide after FU1, there 
is also an abbreviated safety FU2 visit (at 23–37 days after the last dose of study drug). 
For subjects who transition to the AC-058B303 study without FU2 visit, the FU1 visit 
corresponds to the EOS visit. 
• For subjects who do not enter the extension study, the safety FU period lasts for 30 days 
after the last dose of study drug and includes two safety FU visits (FU1, FU2) at  
14–22 and 30–37 days after the last dose of study drug, respectively. For these subjects, 
the EOS visit corresponds to the 30-day FU visit (FU2) or to the last visit of PTOP 
(i.e., Visit 14A [Week 108] of the PTOP), whichever is last. 
8.3.1.1 Visit 15 – FU1 
The FU1 visit will take place 14–22 days after the last dose of study drug. For subjects 
continuing in the AC-058B303 extension study, it is preferable to schedule the visit after 
the planned completion of the accelerated elimination procedure for teriflunomide. The 
visit includes:

For subjects continuing in the AC-058B303 extension study and in whom compliance with 
teriflunomide elimination procedure was assessed as not sufficient at FU1 visit, an 
abbreviated FU2 will take place between 23 and 37 days after the last dose of study drug. 
The abbreviated FU2 visit includes: 
• Accelerated elimination procedure compliance review 
• Recording of AEs/SAEs,  
• MS relapse  
• Recording of changes in concomitant medications 
If the teriflunomide accelerated procedure is still assessed as not sufficient at abbreviated 
FU2 visit, the subject will be not eligible to enter the extension study and will need to 
perform the remaining assessments scheduled for a full FU2 visit. 
8.3.2 Post-treatment observation period 
Subjects who prematurely discontinue study treatment will perform the EOT and safety 
FU visits (FU1, FU2) and will enter the PTOP which lasts until 108 weeks after 
randomization (i.e., planned EOT period). It consists of an abbreviated schedule of 
assessments at the time of the originally scheduled 12-weekly visits. The timepoints and 
visit windows are the same as the corresponding visits during the treatment period but the 
number of assessments is reduced [see Section 3.1.3.2 and Table 3]. After FU2 has been 
performed, the study visits must continue according to the original visit and assessment 
schedule. If the first PTOP visit window overlaps with FU1 or FU2 visits, visits and 
assessments can be combined.

− come fasted to the site  
− contact their principal investigator / treating neurologist at the clinical site 
immediately in the event of the appearance of any symptoms suggestive of an 
MS exacerbation. 
8.4 Unscheduled visits  
An unscheduled site visit may be performed at any time during the study (between 
scheduled visits), as necessary, at the investigator’s discretion. These visits include (but are 
not limited to) those performed due to safety (e.g., occurrence of an AE, laboratory 
abnormalities), administration of study drug (e.g., re-initiation, return of unused study 
medication, need to initiate treatment with a QT-prolonging drug), and/or MS related issues 
(e.g., relapses). 
The date of the visit and the reason for such visits as well as any data related to study 
assessments performed at unscheduled visits will be recorded in the eCRF. 
8.4.1 Unscheduled visits for relapses (Visits R1, R2, etc.) 
Subjects will be reminded to contact their treating neurologist at the clinical site 
immediately in the event of appearance of any new or worsened neurological symptoms. 
Whenever a subject contacts the principal investigator / treating neurologist reporting the 
appearance of any symptoms suggestive of an MS exacerbation, the principal investigator 
/ treating neurologist will interview the subject and determine the necessity of an 
unscheduled visit for relapse. An unscheduled visit will be organized as soon as possible 
after onset or worsening of the symptom(s) as follows:  
• The principal investigator / treating neurologist will interview and examine the subject 
to determine whether or not a relapse may have occurred since last visit using the 
dedicated relapse assessment questionnaire [see Appendix 17] and the relapse 
symptoms form [see Appendix 18] and decide whether the subject has to be referred to 
the efficacy assessor. 
• In order to exclude potential other reasons for the symptom(s) observed, the principal 
investigator / treating neurologist will need to perform the following assessments: 
− Physical examination 
− Vital signs: pulse rate, body temperature. 
• ‘In the event of the subject’s referral to the efficacy assessor, the latter will perform the 
EDSS and FS within 7 days from the onset or worsening of the symptom(s). The 
decision regarding whether the new or worsened neurological symptoms are considered 
as confirmed or unconfirmed relapse will be made by the principal investigator / 
treating neurologist by assessing the compatibility of the symptoms reported by the

All MS relapses, whether confirmed or unconfirmed during the study, must be reported on 
specific relapse pages of the eCRF. MS relapses and associated symptoms are not to be 
entered on the AE page of the eCRF with the following exceptions: 
MS relapses with fatal outcome (these must always be recorded as AEs on the AE page in 
addition to being reported as SAEs).  
MS relapses that, in the view of the investigator, warrant specific notice due to unusual 
frequency, severity or remarkable clinical manifestations (these should be reported as AEs 
on the AE page of the eCRF and, if applicable, on the SAE form). 
Additionally, the following assessments must be done during those visits: 
• PGI-S of Fatigue (subject completes the questionnaire prior to any clinical assessments 
or interaction with health care providers, preferably while waiting for their 
appointment) 
• SF-36v2TM (subject completes the questionnaire after PGI-S of Fatigue, prior to any 
clinical assessments or interaction with health care providers, preferably while waiting 
for their appointment) 
• Recording of changes in concomitant medications 
• MS relapse 
• EDSS/FS (performed by the efficacy assessor) 
• CGI-C 
• Health care resource utilization since the last visit  
• Recording of AEs and SAEs 
• Schedule an appointment for next visit and instruct subject to: 
− come fasted to the site  
− contact their principal investigator / treating neurologist at the clinical site 
immediately in the event of the appearance of any symptoms suggestive of an 
MS exacerbation 
• Give instruction for completion of FSIQ-RMS [see Section 7.2.7].  
If a relapse visit is within 5 days prior to the date of a regular visit where MRI is assessed, 
efforts should be made to perform the MRI assessments prior to the start of treatment with 
i.v. corticosteroids. However, if this is not possible, then the MRI should be delayed until 
at least 14 days after the last dose of corticosteroids.

These visits for relapses are additional unscheduled visits. The regular scheduled study 
visits must be resumed according to the original visit and assessment schedule. If the visit 
is within the visit window of a regular visit, the assessments for the relapse unscheduled 
visit are the ones of this regular visit. 
8.4.2 Additional unscheduled visits for re-initiation of study drug (I1, I2, etc.) 
As described in detail in Section 5.1.10, subjects may need to be monitored at the study 
site when re-initiating study drug following a study drug treatment interruption. 
In such cases, there will be two visits; one visit on the day of re-initiation (d1) and an 
additional visit 14 days (+/− 1 day) after the day of re-initiation (d15).  
The following assessments/procedures must be done during the visit on the day of 
re-initiation (d1): 
• 12-lead ECG pre-dose and hourly (+/− 15 min) for up to 12 h post-dose (under the 
responsibility of the first-dose administrator)  
• SBP/DBP pre-dose and hourly (+/− 15 min) for up to 12 h post-dose (under the 
responsibility of the first-dose administrator) 
• Recording of AEs and SAEs 
• IRT call and study drug dispensing 
• The discharge criteria will be applied as described for Day 1. Subjects may be 
discharged from cardiac monitoring if they meet the discharge criteria before 12 h 
post-dose but no sooner than 4 h post-dose [see Section 5.1.11]. 
The following assessments need to be done during the visit 14 days after the day of 
re-initiation: 
• SBP/DBP (pre-dose) 
• 12-lead ECG (pre-dose) 
• Recording of AEs and SAEs 
• IRT call – Return of study drug blisters and unused medication, and dispensing of new 
blisters, if appropriate. 
The date of visit and any data related to study assessments performed during this visit 
(12-lead ECGs, SBP/DBP) will be reported on the specific eCRF pages for unscheduled 
visit for re-initiation of study drug when post-dose monitoring is required.  
These visits for the cardiac monitoring of the subjects for re-initiating study drug when 
post-dose monitoring is required are additional unscheduled visits. The regular scheduled 
study visits must be resumed according to the original visit and assessment schedule. If the 
visit occurs at the same time as a regular visit, all assessments of the regular visit have to 
be performed in addition.

8.5 Unscheduled visits (any other assessment; U1, U2, U3, etc.) 
An unscheduled site visit may be performed at any time during the study (between 
scheduled visits), as necessary, at the investigator’s discretion. The date of the visit and the 
reason for such visits as well as any data related to study assessments performed at 
unscheduled visits will be recorded in the eCRF. During such visits, any of the following 
assessments may be performed at the investigator’s discretion: 
• PGI-S of Fatigue (subject completes the questionnaire prior to any clinical assessments 
or interaction with health care providers, preferably while waiting for their 
appointment) 
• Assessment of concomitant medications 
• Assessment of methods of contraception (for WOCBP only) 
• PFTs 
• SBP/DBP 
• 12-lead ECGs (e.g., in case of need of concomitant treatment with a QT-prolonging 
drug with known risk of Torsades de Pointes [see Appendix 3]) 
• Ophthalmological examination (e.g., presence of visual symptoms suggestive of active 
uveitis [see Section 5.1.13.7]) 
• OCT (e.g., presence of visual symptoms suggestive of macular edema or active uveitis 
[see Section 5.1.13.7]) 
• MRI 
• EDSS/FS 
• FSIQ-RMS 
• CGI-C 
• Physical examination 
• Body temperature 
• Pulse rate (to be assessed only if no 12-lead ECG is performed)  
• Skin examination 
• Measurement of vital signs and/or body weight 
• Complete laboratory tests including: hematology, blood chemistry, viral serology, 
urinalysis, or serum pregnancy test (for WOCBP only) 
• Assessment of AEs and SAEs 
• IRT call – Return of study drug blisters and unused medication, and dispensing of new 
blisters, if appropriate 
• PK – When possible, a PK sample will be collected for all subjects experiencing SAEs. 
In this event, a sample will preferably be collected pre-dose, as early as possible after 
SAE onset, and no later than 7 days after the last dose of study drug. 
Additional unscheduled spirometry will have to be conducted in the event of respiratory 
symptoms (e.g., dyspnea) during the course of the study. Administration of inhaled

short-acting β2 agonist (e.g., albuterol/salbutamol) for symptom relief may be performed 
at the discretion of the investigator. Administration of short-acting β2 agonist will be 
collected in the eCRF. 
If any of the laboratory variables listed in Section 7.3.14.2 needs to be analyzed, this must 
be done at the Central Laboratory, except in case of emergency; if it has been done at a 
local laboratory, results must be recorded in the eCRF [see Section 7.3.14]. 
8.6 Four-weekly pregnancy tests after EOS 
WOCBP [see Section 4.5.1] must have additional urine pregnancy tests on a 4-weekly basis 
until 6 weeks after the first of two tests showing teriflunomide plasma level < 0.02 mg/L 
[see Section 5.1.14]. The visit window for these tests is +/− 4 days. 
These tests can be done by the subject at home. The principal investigator / treating 
neurologist must be informed about the results of this test via phone, and must report it in 
the source data. 
9 
STUDY COMPLETION AND POST-STUDY TREATMENT / 
MEDICAL CARE 
9.1 Study completion  
For an individual subject, EOS is reached when treatment, safety FU and, if applicable, 
PTOP periods have been completed:  
• For subjects who completed the 108-week treatment period and enter the extension 
study, the EOS visit corresponds to the FU visit (FU1) conducted 14–22 days after the 
last dose of study drug, or to the abbreviated FU2 visit conducted 23–37 days after the 
last study drug.  
• For all the other subjects, the EOS visit corresponds to the FU visit (FU2) 30–37 days 
after the last dose of study drug or to the last visit of PTOP (i.e., Visit 14A (Week 108) 
of the PTOP), whichever is latest.  
The reason(s) for discontinuing the study along with who made the decision, if applicable 
(i.e., subject, investigator or Actelion) must be recorded in the eCRF.  
EOS on a study level occurs at the time all subjects have completed their EOS visits, as 
described above. 
9.2 Premature withdrawal from study 
Subjects may voluntarily withdraw from the study for any reason at any time. Subjects are 
considered withdrawn if they state an intention to withdraw further participation in all 
components of the study, die or are lost to FU for any other reason. If a subject withdraws 
consent, no further data will be collected in the eCRF from the date of withdrawal onward.

The investigator may withdraw a subject from the study (without regard to the subject’s 
consent) if, on balance, they believe that continued participation in the study would be 
contrary to the best interests of the subject. Withdrawal from the study may also result from 
a decision by Actelion for any reason, including premature termination or suspension of 
the study [see Section 9.3]. 
A subject who prematurely discontinues study drug is not considered as withdrawn from 
the study and will enter the PTOP period consisting of an abbreviated schedule of 
assessment, at the time of the originally scheduled 12-weekly visits. 
Subjects are considered as lost to FU if all reasonable attempts by the investigator to 
communicate with the individual fail. The site must take preventive measures to avoid a 
subject being lost to FU (e.g., document different ways of contact such as telephone 
number, home address, e-mail address, person to be contacted in case the subject cannot 
be reached). If the subject cannot be reached, the site must make a reasonable effort to 
contact the subject, document all attempts and enter the loss of FU information into the 
eCRF. The following methods must be used: at least three telephone calls must be placed 
to the last available telephone number, and one registered letter must be sent by post to the 
last available home address. Additional methods may be acceptable if they are compliant 
with local rules/regulations (e.g., site staff visit to the subject’s home), respecting the 
subject’s right to privacy. If the subject is still unreachable after all contact attempts listed 
above, she/he will be considered to be lost to FU.  
If premature withdrawal occurs for any reason, the reason for premature withdrawal from 
the study along with who made the decision (subject, investigator or Actelion) must be 
recorded in the eCRF. 
If for whatever reason (except death or loss to FU) a subject was withdrawn from the study, 
the investigator should make efforts to conduct a last visit/contact to assess the safety and 
wellbeing of the subject, collect unused study drug and discuss FU medical care, including 
undergoing the accelerated elimination procedure for teriflunomide. Data obtained during 
this last appointment / telephone call will be recorded in the subjects’ medical records but 
it will not be collected in the eCRF. The investigator must provide FU medical care for all 
subjects who are prematurely withdrawn from the study, or must refer them for appropriate 
ongoing care, as described in Section 9.4. 
9.3 Premature termination or suspension of the study 
Actelion reserves the right to terminate the study at any time globally or locally. 
Investigators can terminate the participation of their site in the study at any time.

If a study is suspended or prematurely terminated, Actelion will promptly inform the 
investigators, the IRBs/IECs and health authorities as appropriate and provide the reasons 
for the suspension or termination.  
If the study is suspended or prematurely terminated for any reason, the investigator in 
agreement with Actelion must promptly inform all enrolled subjects and ensure their 
appropriate treatment and FU, as described in Section 9.2. The investigator may be 
informed of additional procedures to be followed in order to ensure that adequate 
consideration is given to the protection of the subjects’ interests. 
In addition, if the investigator suspends or terminates a study without prior agreement from 
Actelion, the investigator must promptly inform Actelion and the IRB/IEC, and provide 
both with a detailed written explanation of the termination or suspension. 
If the IRB/IEC suspends or terminates its approval/favorable opinion of a study, the 
investigator must promptly notify Actelion and provide a detailed written explanation of 
the termination or suspension. 
Any suspension or premature termination of the study must be discussed with the IDMC. 
9.4 Medical care of subjects after study completion / withdrawal from study 
After the subject’s study completion or premature withdrawal from the study, whichever 
applies, the investigator/delegate will explain to subjects what treatment(s) / medical care 
is necessary and available according to local regulations.  
An extension study with ponesimod treatment, conducted under a separate protocol, will 
be considered for subjects who complete the 108-week treatment as scheduled.  
10 SAFETY DEFINITIONS AND REPORTING REQUIREMENTS 
10.1 Adverse events 
10.1.1 Definitions of adverse events 
An AE is any adverse change, i.e., any unfavorable and unintended sign, including an 
abnormal laboratory finding, symptom or disease that occurs in a subject during the course 
of the study, whether or not considered by the investigator as related to study treatment.  
A treatment-emergent AE is any AE temporally associated with the use of study treatment 
(from study treatment initiation until 15 days after study treatment discontinuation), 
whether or not considered by the investigator as related to study treatment. 
AEs include: 
• Exacerbation of a pre-existing disease with the exception of MS relapse and associated 
symptoms [see Section 10.1.6].

• Increase in frequency or intensity of a pre-existing episodic disease or medical 
condition. 
• Disease or medical condition detected or diagnosed during the course of the study even 
though it may have been present prior to the start of the study. 
• Continuous persistent disease or symptoms present at study start that worsen following 
the start of the study.  
• Abnormal assessments, e.g., change on physical examination, ECG findings, if they 
represent a clinically significant finding that was not present at study start or worsened 
during the course of the study. 
• Laboratory test abnormalities if they represent a clinically significant finding, 
symptomatic or not, that was not present at study start or worsened during the course 
of the study or led to dose reduction, interruption or permanent discontinuation of study 
treatment.  
Overdose, misuse and abuse of the study treatment should be reported as an AE and, in 
addition, study treatment errors must be documented in the study drug log of the eCRF. 
10.1.2 Intensity of adverse events 
The intensity of clinical AEs is graded on a three-point scale – mild, moderate, severe – 
and is reported on specific AE pages of the eCRF.  
If the intensity of an AE worsens during study treatment administration, only the worst 
intensity should be reported on the AE page. If the AE lessens in intensity, no change in 
the severity is required. 
If the intensity of an AE with an onset date between informed consent signature and start 
of study treatment and which is ongoing at the start of treatment worsens after the start of 
study treatment, a new AE page must be completed. The onset date of this new AE 
corresponds to the date of worsening in intensity. 
The three categories of intensity are defined as follows: 
 Mild 
The event may be noticeable to the subject. It does not influence daily activities and does 
not usually require intervention. 
 Moderate 
The event may make the subject uncomfortable. Performance of daily activities may be 
influenced, and intervention may be needed.

EudraCT 2012-000540-10 
Doc No D-18.388 
 
 Severe 
The event may cause noticeable discomfort and usually interferes with daily activities. The 
subject may not be able to continue in the study, and treatment or intervention is usually 
needed. 
A mild, moderate, or severe AE may or may not be serious [see Section 10.3.1]. These 
terms are used to describe the intensity of a specific event. Medical judgment should be 
used on a case-by-case basis.  
Seriousness, rather than severity assessment, determines the regulatory reporting 
obligations. 
10.1.3 Relationship to study treatment  
Each AE must be assessed by the investigator as to whether or not there is a reasonable 
possibility of causal relationship to the study treatment, and reported as either related or 
unrelated. The determination of the likelihood that the study drug caused the AE will be 
provided by an investigator who is a qualified physician. 
10.1.4 Adverse events associated to study design or protocol-mandated procedures 
An AE is defined as related to study design or protocol-mandated procedures if it appears 
to have a reasonable possibility of a causal relationship to either the study design or to 
protocol-mandated procedures. Examples include discontinuation of a subject’s previous 
treatment during a washout period leading to exacerbation of underlying disease. 
10.1.5 Reporting of adverse events 
All AEs occurring after study start (i.e., signing of informed consent) and up to 30 days 
after study treatment discontinuation or up to initiation of study treatment in the extension 
study or up to the last visit of PTOP (i.e., Week 108 visit of the PTOP) (whichever is latest; 
extension study conducted under a separate protocol) must be recorded on specific AE 
pages of the eCRF. Actelion may contact the investigator to obtain further information.  
Cardiac events 
The first-dose administrator [see Section 3.3.4] must ensure that blinded study personnel 
at the study site, such as the treating neurologists, efficacy assessor, clinical coordinator / 
study nurse, and other personnel involved in the clinical care and management of the 
subject, do not have access to Day 1 and day of re-initiation of study drug post-dose BP 
assessment or ECG interpretation reports, or to AEs with onset on Day 1 or on the first day 
of re-initiation of study drug which have an onset after study drug intake and are resolved 
at the time of discharge from cardiac monitoring.  
However, significant findings (e.g., new ECG abnormalities, bradycardia) that meet the 
definition of an AE must be recorded on the AE page of the eCRF.

Doc No D-18.388 
 
On Day 1 and on the first day of re-initiation of study drug when post-dose monitoring is 
required, significant findings that, in view of the first-dose administrator, meet the 
definition of an AE, have an onset after the study drug intake, and are resolved at the time 
of discharge of the subject from cardiac monitoring, must be reported directly on the AE 
page of the separate eCRF by the first-dose administrator/delegate. These AEs will not be 
visible to any of the blinded study personnel at the study site. All other significant findings 
on Day 1 and on the first day of re-initiation of study drug when post-dose monitoring is 
required but unresolved at the time of discharge from cardiac monitoring of the subject, 
which in her/his view meet the definition of an AE, must be reported to the principal 
investigator / treating neurologist who will record these events on the AE page of the eCRF. 
Similarly, any AEs with onset on Day 1 or on the first day of study drug re-initiation when 
post-dose monitoring is required leading to the premature discontinuation of study drug 
must be reported by the first-dose administrator to the principal investigator / treating 
neurologist who will record these events on the AE page of the eCRF. 
10.1.6 Reporting of MS relapse 
All MS relapses during the study must be reported on specific relapse pages of the eCRF. 
MS relapses and associated symptoms are not to be entered on the AE page of the eCRF 
with the following exceptions: 
• MS relapses with fatal outcome (these must always be recorded as AEs on the AE page 
in addition to being reported as SAEs).  
• MS relapses that, in the view of the investigator, warrant specific notice due to unusual 
frequency, severity or remarkable clinical manifestations (these should be reported as 
AEs on the AE page of the eCRF and, if applicable, on the SAE form).  
10.1.7 Follow-up of adverse events 
AEs still ongoing more than 30 days after study treatment discontinuation must be followed 
up until they are no longer considered clinically relevant, or until the event outcome is 
provided. 
10.2 Serious adverse events 
10.2.1 Definitions of serious adverse events 
10.2.1.1 Serious adverse events 
An SAE is defined by the ICH guidelines as any AE fulfilling at least one of the following 
criteria: 
• Fatal.

• Life-threatening: refers to an event in which the subject was at risk of death at the time 
of the event. It does not refer to an event that hypothetically might have caused death 
had it been more severe. 
• Requiring inpatient hospitalization or prolongation of existing hospitalization. 
• Resulting in persistent or significant disability or incapacity. 
• Congenital anomaly or birth defect. 
• Medically significant: refers to important medical events that may not immediately 
result in death, be life-threatening, or require hospitalization but may be considered to 
be SAEs when, based upon appropriate medical judgment, they may jeopardize the 
subject and may require medical or surgical intervention to prevent one of the outcomes 
listed in the definitions above.  
The following reasons for hospitalization are exempted from being reported:  
• Hospitalization for cosmetic elective surgery, or social and/or convenience reasons. 
• Hospitalization for MS relapse (with the exceptions described in Section 10.1.6). 
• Hospitalization for pre-planned (i.e., planned prior to signing informed consent) 
surgery or standard monitoring of a pre-existing disease or medical condition that did 
not worsen, e.g., hospitalization for coronary angiography in a subject with stable 
angina pectoris. 
However, complications that occur during hospitalization are AEs or SAEs (e.g., if a 
complication prolongs hospitalization). 
10.2.1.2 Serious adverse events associated with the study design or protocol-mandated 
procedures  
An SAE is defined as related to study design or protocol-mandated procedures if it appears 
to have a reasonable possibility of a causal relationship to either the study design or to 
protocol-mandated procedures. Examples include discontinuation of a subject’s previous 
treatment during a washout period leading to exacerbation of underlying disease or a 
complication of an invasive procedure that is specifically required by the protocol. 
10.2.2 Reporting of serious adverse events  
10.2.2.1 During pre-randomization period  
All SAEs that occur after study start (i.e., signing of informed consent) must be reported 
(whether considered associated or not associated with study design or study-mandated 
procedures).  
These SAEs must be reported on an SAE form and also in the eCRF.

10.2.2.2 During treatment period 
All SAEs, regardless of investigator-attributed causal relationship, must be reported. 
These SAEs must be reported on an SAE form and also on the AE pages in the eCRF. 
10.2.2.3 During 30-day follow-up period 
All SAEs, regardless of investigator-attributed causal relationship, that occur up to 30 days 
after study treatment discontinuation, must be reported on AE pages in the eCRF and on 
an SAE form.  
10.2.3 Follow-up of serious adverse events  
SAEs still ongoing at the EOS visit must be followed up until resolution or stabilization, 
or until the event outcome is provided, e.g., death.  
10.2.4 After the 30-day follow-up period  
10.2.4.1 During the PTOP period (if applicable) 
All SAEs, regardless of investigator-attributed causal relationship, that occur during the 
PTOP period must be reported on AE pages in the eCRF and on an SAE form. 
10.2.4.2 After the PTOP period 
New SAEs occurring after the 30-day FU period, or after the last visit of PTOP (whichever 
applies and is last) must be reported to the Actelion drug safety department within 24 h of 
the investigator’s knowledge of the event, only if considered causally related to previous 
exposure to the study treatment by the investigator.  
10.2.5 Reporting procedures 
All SAEs must be reported by the investigator to the Actelion drug safety department 
within 24 h of the investigator’s first knowledge of the event. 
MS relapses and associated symptoms are exempted from being reported on an SAE 
form by the investigator to the Actelion drug safety department with the exceptions 
described in Section 10.1.6.  
All SAEs must be recorded on an SAE form, irrespective of the study treatment received 
by the subject, and whether or not this event is considered by the investigator to be related 
to study treatment.  
The SAE forms must be faxed to the Actelion drug safety department (contact details are 
provided on the SAE form). The investigator must complete the SAE form in English, and 
must assess the causal relationship of the event to study treatment.

FU information about a previously reported SAE must also be reported within 24 h of 
receiving it. The Actelion drug safety department may contact the investigator to obtain 
further information.  
If the subject is hospitalized in a hospital other than the study site, it is the investigator’s 
responsibility to contact this hospital to obtain all SAE relevant information and 
documentation. 
The reference safety documents to assess expectedness of a suspect serious adverse 
reaction and reported by the sponsor to health authorities, IRBs/IECs and investigators are 
the reference safety information section of the IB [Ponesimod IB] and reference safety 
information of the Aubagio® Summary of Product Characteristics.  
MS relapses and associated symptoms are commonly seen with the underlying disease and 
are therefore expected to occur in this subject population. The MS relapses and associated 
symptoms reported as serious (unless fatal) are waived and will be treated as expected and 
will therefore not require systematic unblinding or expedited reporting to health authorities, 
IRBs/IECs, and investigators. However, all MS relapses (irrespective of seriousness) will 
be collected on the specific relapse pages of the eCRF in the clinical trial database and 
monitored during the study by the sponsor and by the IDMC. 
10.3 Pregnancy 
If a woman becomes pregnant while on study treatment, study treatment must be 
discontinued. The investigator must counsel the subject and discuss the risks of continuing 
with the pregnancy and the possible effects on the fetus. If the woman wishes to continue 
pregnancy, Actelion Global Drug Safety will request the unblinding of the treatment 
assignment and only the subject allocated to teriflunomide will have to perform an 
accelerated elimination procedure. 
10.3.1 Reporting of pregnancy 
Irrespective of the treatment received by the subject, any pregnancy occurring during the 
study including during the 30 days following study treatment discontinuation and the entire 
duration for continued contraception after EOT, as mandated by the protocol 
[see Section 5.1.14], must be reported within 24 h of the investigator’s knowledge of the 
event.  
Pregnancies must be reported on the Actelion Pregnancy form, which is faxed to the 
Actelion drug safety department (see contact details provided on the Actelion Pregnancy 
form), and on the AE page in the eCRF. 
Any pregnancy diagnosed in the female partner of a male subject during treatment with the 
investigational product must be reported to Actelion within 24 h of the investigator’s

knowledge of the event. A Pregnant partner information release form will be provided to 
the pregnant partner prior to collecting any information on the pregnancy and its outcome. 
10.3.2 Follow-up of pregnancy  
Any pregnancy must be followed to its conclusion and its outcome must be reported to the 
Actelion drug safety department. 
Any AE associated with the pregnancy occurring during the FU period after study drug 
discontinuation must be reported on separate AE pages in the eCRF. Any SAE occurring 
during the pregnancy must be reported on an SAE form as described in Section 10.2.2. 
10.4 Study safety monitoring 
Clinical study safety information (AEs, SAEs, laboratory values, ECGs, vital signs, and 
project-specific labs/examinations as required) is monitored and reviewed on a continuous 
basis by the Actelion clinical team (in charge of ensuring subjects’ safety as well as data 
quality) by periodically monitoring clinical study activities from protocol conception to 
database closure. In addition, an IDMC is monitoring safety data [see Section 3.4]. 
11 STATISTICAL METHODS 
All statistical analyses will be conducted by Actelion or by designated CROs supervised 
by Actelion. 
The SAP(s) for the final analyses will be approved prior to database lock. The SAP for the 
clinical study report will provide the full details of all analyses, data displays, and 
algorithms to be used for data derivations. Separate SAPs and reports are planned for the 
final analyses of PK data, the MRI sub-study, and the Patient Preference sub-study.  
A separate SAP for the blinded interim analysis to determine the FSIQ-RMS response 
thresholds will be finalized shortly after the first subject is enrolled into the study.  
All data will be listed and endpoints will be summarized by appropriate descriptive 
statistics (tables or figures), typically including: 
• Number of non-missing observations, number of missing observations, mean, standard 
deviation, minimum, median, Q1, Q3, and maximum for continuous endpoints; 
• Number of non-missing observations, number of missing observations and frequency 
with percentage per category (percentages based on the number of non-missing 
observations) for categorical endpoints; 
• Number of subjects at risk, cumulative number of events, cumulative number of 
censored observations and Kaplan-Meier estimates of the survival function for 
time-to-event endpoints.

Absolute changes from baseline are defined as post-baseline value minus baseline value, 
i.e., a positive sign indicates an increase as compared to baseline. 
A percentage (relative) change from baseline is defined as the absolute change from 
baseline divided by the baseline value (if the baseline value does not equal 0) multiplied 
by 100. 
The baseline value for efficacy is defined as the last non-missing value recorded prior to 
randomization for each endpoint and each subject individually. The baseline value for 
safety is defined as the last non-missing value recorded prior to first study drug intake for 
each endpoint and each subject individually unless stated otherwise in the SAP.  
The EOS is defined as the date on the End-of-Study eCRF page. If this date is missing the 
last recorded visit on the eCRF is considered as the EOS date.  
The EOT date is defined as the date of the last dose of study treatment intake.  
11.1 Analysis Sets 
11.1.1 Screened Analysis Set 
The screened analysis set (SCR) includes all subjects who were screened and received a 
subject number. 
11.1.2 Full Analysis Set 
The Full Analysis Set (FAS) includes all randomized subjects.  
All primary statistical analyses of efficacy endpoints will be based on the FAS. In order to 
adhere to the intention-to-treat principle as much as possible:  
• In order to preserve the randomization subjects will be evaluated according to the 
treatment they have been randomized to (which may be different to the treatment they 
have received) and stratum information used for randomization as recorded in the 
Interactive Voice Response System (which may be different to the information 
available on the eCRF after data validation); 
• Unless otherwise stated, all available efficacy data up to the EOS date will be included, 
irrespective of whether a subject has stopped study treatment earlier or has received 
any MS treatment other than that to which the subject was randomized to. 
11.1.3 Per-Protocol Set 
The Per-Protocol Set (PPS) comprises all subjects included in the FAS without any major 
protocol deviations, that impact the assessment of the primary/secondary endpoints, 
occurring prior to or at randomization. Due to the nature of the primary endpoint which is 
assessed over the entire study period rather than at a fixed timepoint, only the data accrued

after occurence of a major protocol deviation will be excluded for the PPS analysis for a 
given subject.  
All reportable protocol deviations will be evaluated before unblinding and classified into 
the four categories below.  
Subjects will be excluded from the PPS if: 
• Subject is randomized and did not satisfy certain eligibility criteria; 
Data will be excluded for subjects after the occurrence of one of the following criteria: 
• Subject received the wrong study treatment or incorrect dose;  
• Subject took an unauthorized concomitant medication;  
• Occurrence of major protocol deviation that could confound the interpretation of 
analysis conducted on the FAS.  
Additional details regarding the definition of the reasons for subject/data exclusion from 
the PPS will be defined in the final SAP. 
11.1.4 Safety Set 
The safety set (SAF) includes all randomized subjects who received at least one dose of 
study treatment. Subjects will be analyzed based on actual treatment taken. 
11.1.5 FSIQ-RMS Measurement Set 
An FSIQ-RMS measurement set (FMS) includes the first 291 randomized subjects who 
received at least one dose of study treatment [see Section 11.5.5 for sample size 
justification]. 
11.1.6 Other analysis sets 
Other analysis datasets are defined in the corresponding SAPs, e.g., PK populations, 
sub-study populations, and subgroups of (special) interest. 
11.1.7 Usage of the analysis sets 
The FAS and the PPS are used for the analysis of the primary and the secondary endpoints. 
Results for the primary and secondary efficacy endpoints based on the PPS will supplement 
those based on the FAS and assess the robustness of treatment effects. 
MRI, clinical exploratory endpoints and other clinical exploratory endpoints will be 
analyzed using the FAS. 
The FMS will be used for the confirmation of the threshold values for the minimal level of 
change required to identify FSIQ-RMS responders. 
All safety data will be analyzed using the SAF.

11.2 Variables 
11.2.1 Primary efficacy variable  
The primary endpoint is the ARR defined as the number of confirmed relapses per 
subject-year. All relapses up to EOS (including the FU period and PTOP) will be included 
in the analysis. For the statistical analysis of the ARR, the following variables will be used:  
• 
The Subject’s number of confirmed relapses up to EOS;  
• 
Length of observation expressed in years, defined as: [EOS date minus date of 
randomization + 1] divided by 365.25

11.2.2 Secondary efficacy variables 
There are four secondary efficacy endpoints, which will be analyzed as per the statistical 
testing strategy outlines in Section 11.3.1: 
• Change from baseline to Week 108 in fatigue-related symptoms as measured by the 
symptoms domain of the FSIQ-RMS;  
• Cumulative number of CUAL from baseline to Week 108; 
• Time to 12-week CDA from baseline to EOS;  
• Time to 24-week CDA from baseline to EOS. 
11.2.2.1 Fatigue Symptoms and Impact Questionnaire (FSIQ-RMS) 
The endpoint is defined as the absolute change in the FSIQ–RMS (weekly) symptoms score 
from baseline to Week 108. Additional details will be provided in the SAP. 
11.2.2.2 Cumulative number of CUAL from baseline to Week 108 
Cumulative number of CUAL [defined in Section 6.1.2] from baseline to Week 108 is 
calculated as the sum of lesions at all post-baseline MRI visits up to Week 108. 
11.2.2.3 Time to 12-week CDA 
Time to 12-week CDA from baseline to EOS is defined as: 
• Increase of at least 1.5 in EDSS for subjects with a baseline EDSS score of 0; 
• Increase of at least 1.0 in EDSS for subjects with a baseline EDSS score of 1.0 to 5.0; 
• Increase of at least 0.5 in EDSS for subjects with a baseline EDSS score ≥ 5.5; 
confirmed after 12 weeks, see detailed definition in Section 6.1.2.

Time to first 12-week CDA is defined as start date of the first 12-week CDA minus date of 
randomization +1 in days.  
For a subject without a 12-week CDA, the censored time to 12-week CDA is defined as: 
• [date of last EDSS assessment for subjects without an EDSS increase (as defined 
above) at their last visit or date of EDSS visit prior to the last visit if there is an increase 
at the last visit] minus date of randomization + 1.  
This will constitute a right-censored observation. 
Further details of the derivation of this variable will be provided in the SAP. 
11.2.2.4 Time to 24-week CDA 
Time to 24-week CDA from baseline to EOS is defined as EDSS increase described in 
Section 6.1.2 confirmed after 24 weeks.  
Time to first 24-week CDA is defined as start date of the first 24-week CDA minus date of 
randomization +1 in days.  
For a subject without a 24-week CDA, the censored time to 24-week CDA is defined as: 
• [date of last EDSS assessment without an EDSS increase (as defined above)] minus 
date of randomization + 1.  
This will constitute a right-censored observation. Further details of the derivation of this 
variable will be provided in the SAP.

11.3 Description of statistical analyses 
11.3.1 Overall testing strategy 
The primary endpoint (ARR using confirmed relapses) will be tested using a negative 
binomial regression model, comparing the investigational treatment (ponesimod 20 mg) 
with the comparator (teriflunomide 14 mg) at full alpha.  
If the primary endpoint null hypothesis is rejected, the alpha will be split evenly (1/3 of 
alpha) between the following three secondary endpoints using the fallback procedure, 
allowing for passing on alpha within the fallback procedure as per the following sequence: 
• Change from baseline to Week 108 in fatigue-related symptoms as measured by the 
symptoms domain of the FSIQ–RMS [Fatigue] 
• Cumulative number of CUAL from baseline to Week 108 [CUALs] 
• Time to 12-week CDA from baseline to EOS [12-week CDA]  
If a secondary endpoint listed as part of the fallback procedure above is successful, the 
preserved alpha in the sequence is passed along to the next secondary endpoint in the 
sequence and the summed alpha is used for testing that endpoint. Thus, as sequential tests 
are successful, the alpha accumulates for the endpoints later in the sequence; these 
endpoints are then potentially tested with a progressively larger alpha, but always with at 
least 1/3 of the alpha. 
In a last step, the secondary endpoint  
• Time to 24-week CDA from baseline to EOS [24-week CDA] 
is tested in a subsequent stage following Time to 12-week CDA with the remaining alpha.  
A graphical description of this testing strategy for the primary and secondary endpoints 
following the approach of Bretz, et al. [Bretz 2009] is provided in Figure 8.

Figure 8 
Overall testing strategy 
 
The primary null hypothesis will be tested at a two-sided 1% alpha level, and if this is 
rejected the study will be declared to show conclusive evidence of efficacy. If the primary 
null hypothesis can only be rejected at the two-sided 5% alpha level, the study will be 
declared positive.  
Analyses for secondary endpoints will be conducted at an overall two-sided 5% alpha level, 
with multiplicity adjustment as per the testing strategy outlined in Figure 8. 
11.3.2 Analysis of the primary efficacy variable 
11.3.2.1 Hypotheses and statistical model 
A generalized linear model with negative binomial distribution for the number of 
confirmed relapses will be assumed.

Yj 
denotes the number of relapses for subject j during tj 
µj

Two-sided hypotheses are expressed in terms of the model parameters µP20mg and µT14mg. 
The primary null hypothesis is that the ARR (µ) does not differ between ponesimod 20 mg 
and teriflunomide 14 mg. The alternative hypothesis is that the ARR differs between 
ponesimod 20 mg and Teriflunomide 14 mg. 
H0, ARR: µP20mg - µT14mg = 0  
vs 
H1, ARR: µP20mg - µT14mg ≠ 0  
The null hypothesis will be tested by a two-sided Wald test within the negative binomial 
regression model [see Section 11.3.2.3], with a two-sided significance level of 0.01 for 
conclusive evidence and 0.05 for a positive study. Two-sided 95% and 99% Wald CIs will 
be calculated for the relative reduction in mean ARR for ponesimod 20 mg compared to 
teriflunomide 14 mg. 
11.3.2.2 Handling of missing data 
11.3.2.2.1 Main analysis of the primary endpoint 
All confirmed relapses from randomization up to the EOS visit for subjects in the FAS will 
be used in the main analysis of the primary endpoint regardless of study drug compliance; 
therefore no data will be excluded from the analysis.  
Every effort will be made to collect as complete relapse information as possible, with a 
focus on collecting all start dates and all EDSS/FS data required for the relapses to make a 
correct evaluation of relapse confirmation. All relapses with missing or incomplete start 
dates will be included in the primary efficacy analysis, unless it is clear that they have 
occurred prior to randomization. No other missing data imputation is used for the main 
analysis of the primary endpoint.  
11.3.2.2.2 Sensitivity analyses of the primary endpoint 
Missing data will be assessed in a number of ways to test the robustness of the primary 
endpoint results and to ensure that selection bias/informative drop-outs have not had an 
influence on the results.  
New or Worsening Neurological Symptoms Considered as relapses: 
New or worsening neurological symptoms are reported via a telephone interview or at the 
site in a face-to-face interview and at both these times a decision must be taken by the 
treating neurologist to refer the subject to the efficacy assessor. Once referred to the 
efficacy assessor the symptom is considered a relapse and is assessed for confirmation. To 
ensure there is no bias in the selection of symptoms considered as relapses between 
treatments, an analysis will compare the proportion of these new or worsening neurological

symptoms that are considered as relapses and as confirmed relapses. If there is an 
imbalance in the selection between treatments, this will be explored further.  
Early Study Withdrawal: 
To assess the impact of subjects withdrawing from the study prior to Week 108 (+ FU 
period) a number of sensitivity analyses will be performed. These include the imputation 
of confirmed relapses using various assumptions for the period with missing data. The 
proportion of missing data will be calculated as:  
1-  
Cumulative time between randomization and EOS
Cumulative time between randomization and theoretical Week 108 
A worst case imputation will impute the observed ARR for ponesimod subjects up to EOS 
during the period EOS up to Week 108 and impute zero relapses for the teriflunomide 
subjects during this period. A second approach will impute the observed teriflunomide 
ARR up to EOS for the period EOS up to Week 108 for both treatments, using simulations 
and bootstrapping techniques to calculate the 95% and 99% CIs. A third and more 
conservative approach will impute the observed individual treatment ARR up to EOS for 
the period EOS up to Week 108. 
11.3.2.3 Main analysis 
The primary statistical analysis will be performed on the FAS population using the model 
described in Section 11.3.2.1 for confirmed relapses, with the stratification variables (prior 
use of DMTs and EDSS category), as well as the number of relapses in the year prior to 
study entry and the logarithm of time on treatment up to EOS as an offset variable, included 
in the model.  
11.3.2.4 Supportive/sensitivity analyses 
The following supportive analyses (based on the FAS, if not otherwise stated) are planned 
using the model described in Section 11.3.2.1: 
• ARR only counting confirmed relapses occurring up to EOT + 7 days; 
• Analysis with treatment as the only covariate in the model for all confirmed relapses up 
to EOS; 
• Analysis adjusting for the stratification covariate using the actual EDSS at baseline and 
prior use of DMTs as recorded on the eCRF for all confirmed relapses up to EOS and 
up to EOT + 7 days; 
• Analysis counting only confirmed relapses up to starting alternative MS treatments or 
EOS for subjects not switching; 
• Analyses using different methods of relapse imputation between EOT + 7 days and EOS 
(PTOP) to further assess the impact of treatment discontinuation and/or switching to 
alternative MS treatments;

additional inferential analysis will be described if deemed necessary.  
Further analyses will be described in the SAP. 
11.3.2.5 Subgroup analyses 
The ARR within each level of each subgroup will be analyzed using an unadjusted negative 
binomial model. Subgroups of interest (including the stratification factors) are: 
• Baseline EDSS (≤ 3.5, > 3.5); 
• Geographical region (North America, Latin America, Western Europe, Eastern Europe, 
Rest of the World); 
• Gender (male, female); 
• Age (< 40, ≥ 40); 
• MS subtype (relapsing remitting, secondary progressive with superimposed relapses); 
• Prior MS treatment (yes, no); 
• Relapse in the year prior to study entry (≤ 1, ≥ 2); 
• Gd+ T1 lesions at Baseline (absent, present); 
• Highly active disease (yes, no). A subject is considered to have highly active disease if 
one or both of the following conditions are met: 
 Any MS disease modifying therapy received in the 12 months prior to study 
and one or both of the following conditions are met: 
 ≥ 1 relapse within the last 12 months prior to study and baseline MRI 
shows either ≥ 1 Gd+ T1 lesion and/or ≥ 9 T2lesions  
 ≥ 1 relapse within the last 24 months prior to study and number of 
relapses in the 12 months prior to study ≥ number of relapses between 
24 and 12 months prior to study. 
 ≥ 2 relapses within the last 12 months prior to study and baseline EDSS > 2 and 
≥ 1 Gd+ T1 lesion on baseline MRI. 
Further subgroup analyses might be performed using other baseline characteristics and 
other variables. The analyses including interaction tests will be specified in more detail in 
the SAP.

11.3.3 Analysis of the secondary efficacy variables 
The secondary efficacy endpoints will be tested as outlined in Section 11.3.1 if the primary 
analysis on ARR has led to the rejection of the null hypothesis in favor of ponesimod 
20 mg.  
The endpoints will be analyzed using the FAS. All secondary endpoints will also be 
analyzed using the PPS. 
11.3.3.1 Absolute change in FSIQ-RMS from baseline to Week 108 
11.3.3.1.1 Hypothesis 
The FSIQ-RMS weekly symptoms score ranges from 0 to 90 with a higher score indicating 
more pronounced fatigue. A repeated measurement ANCOVA will be used to compare the 
change from baseline to Week 108 across both treatment groups. The underlying 
hypotheses are expressed as two means, assuming the outcomes of the endpoint for both 
treatments are normally distributed: 
H0, FSIQ: µP20mg - µT14mg = 0  
  
vs 
H1, FSIQ: µP20mg - µT14mg ≠ 0  
 
Each null hypothesis will be tested by an F-test by comparing the resulting p-value to the 
local alpha as per the overall testing strategy, see Section 11.3.1. 
11.3.3.1.2 Main Analysis  
The main analysis for this variable will be performed on the FAS comparing ponesimod 
20 mg to teriflunomide 14 mg using a repeated measurements ANCOVA model with 
baseline, prior use of DMTs, EDSS category and the FSIQ symptoms score at baseline as 
covariates. 
11.3.3.1.3 Supportive analyses 
The following supportive analyses (based on the FAS if not otherwise stated) are planned: 
• Analysis with treatment as the only factor within subgroups levels; 
• Analysis based on the PPS. 
11.3.3.2 Cumulative number of combined unique active lesions 
11.3.3.2.1 Hypothesis 
Two-sided hypotheses are expressed in terms of the model parameters µP20mg and µT14mg. 
The primary null hypothesis is that the CUAL (µ) does not differ between ponesimod

20 mg and teriflunomide 14 mg. The alternative hypothesis is that the CUAL differs 
between ponesimod 20 mg and teriflunomide 14 mg. 
H0, CUAL: µP20mg - µT14mg = 0  
vs 
H1, CUAL: µP20mg - µT14mg ≠ 0  
The null hypothesis will be tested by a two-sided Wald test within the negative binomial 
regression model [see Section 11.3.1], by comparing the resulting p-value to the local alpha 
as per the overall testing strategy, see Section 11.3.1. Two-sided 95% Wald CIs will be 
calculated for the relative reduction in mean CUAL for ponesimod 20 mg compared to 
teriflunomide 14 mg. 
11.3.3.2.2 Main Analysis

use of DMTs and EDSS category, as well as the presence of T1 Gd+ lesions at baseline, 
included in the model.  
11.3.3.2.3 Supportive analyses 
The following supportive analyses (based on the FAS if not otherwise stated) are planned 
using the same type of model, but: 
• based on the PPS; 
• subgroup analyses with subgroups defined by baseline characteristics. 
11.3.3.3 Time to 12-week CDA 
11.3.3.3.1 Hypothesis 
Hypotheses are formulated in terms of “survival” functions S(t), i.e., the probability that 
time to 12-week CDA is ≥ t for a day t relative to the date of randomization. Two-sided 
hypotheses are expressed in terms of the survival functions SP20mg (t) and ST14mg (t). 
H0,CDA: SP20mg (t) = ST14mg (t) for all t ≥ 0  
vs 
H1,CDA: SP20mg (t) ≠ ST14mg (t) for all t ≥ 0 
The null hypothesis will be tested using a two-sided stratified log-rank test by comparing 
the resulting p-value to the local alpha as per the overall testing strategy, see Section 11.3.1.

visit) are considered as confirmed. 
11.3.3.4 Time to 24-week CDA 
11.3.3.4.1 Hypothesis 
Hypotheses are formulated in terms of “survival” functions S(t), i.e., the probability that 
time to 24-week CDA is ≥ t for a day t relative to the date of randomization. Two-sided 
hypotheses are expressed in terms of the survival functions SP20mg (t) and ST14mg (t). 
H0,CDA24: SP20mg (t) = ST14mg (t) for all t ≥ 0  
vs 
H1,CDA24: SP20mg (t) ≠ ST14mg (t) for all t ≥ 0 
The null hypothesis will be tested using a two-sided stratified log-rank test by comparing 
the resulting p-value to the local alpha as per the overall testing strategy, see Section 11.3.1.

11.4 Interim analyses 
No unblinded interim analysis is planned for the study; however, a blinded interim analysis 
based on the first 291 randomized subjects will be performed in order to confirm the 
definition of FSIQ responders. 
In order to understand and interpret change in the FSIQ-RMS Fatigue Symptoms endpoint 
within this clinical population, it is important to anchor this change to a meaningful 
threshold of change from the clinician and patient perceptions. The first threshold, the 
Minimally Important Differences (MID), is computed as the smallest difference in scores 
between groups in the domain of interest that patients perceive as beneficial. Similarly, the 
Clinically Important Differences (CID) is computed as another threshold in which the 
clinician perceives the change as beneficial. There are multiple methods to compute 
Minimally Clinically Important Differences, which include: patient perspective, clinician 
perspective, and data-driven approaches (anchor- and distribution-based). Comparison of 
these methods allows for the approximation of MID and CID responder thresholds.  
Within this study, two anchors have been selected for evaluating change on the FSIQ-RMS 
Fatigue Symptom score: the PGI-S of Fatigue for patient-reported change in fatigue 
severity and the CGI-C for the clinician’s global impression of the patient’s MS severity. 
Each will be collected simultaneously to the FSIQ-RMS measures. 
For the blinded FSIQ responder definition analysis, the MID as assessed by subjects will 
be measured using a common distribution-based method: ½ standard deviation change 
from baseline of the FSIQ-RMS Fatigue Symptom score based on the FMS. Anchor-based 
estimates for the MID will group subjects based on change on the PGI-S of Fatigue from 
baseline to each subsequent visit. Anchor-based methods for the CID calculation as 
assessed by clinician’s grouped improvement categories on the CGI-C from weekly 
baseline and subsequent visit scores. Effect size estimates for each group of subjects will 
be calculated as the mean score difference between weekly baseline and subsequent visit 
scores, divided by the pooled baseline standard deviation. Cohen’s thresholds for 
interpreting the magnitude of an effect size suggests the following: 0.2 (small), 0.5 
(moderate), and 0.8 (large). As such, the expectation for interpreting the MID and CID are 
effect-size estimates greater than 0.2, which is considered the minimal amount of change 
necessary for detecting meaningful improvement.

11.5 Sample size 
The sample size is calculated based on the primary endpoint, and the power is calculated 
for the secondary endpoints. For the secondary endpoint FSIQ-RMS, no sample size 
calculations were carried out as valid assumptions are difficult to make due to the recent 
release of the endpoint.  
11.5.1 Primary endpoint 
The sample size for the study was determined by a simulation using the negative binomial 
distribution. A sample size of 1100 subjects (550 per treatment group) will provide a power 
of approximately 90% for a significance level of 0.01, under the assumption that ARR is 
0.320 for teriflunomide 14 mg and 0.215 for ponesimod 20 mg (which corresponds to a 
risk reduction of 33%), and using a dispersion = 0.9. An annual dropout rate of 
approximately 15% has been assumed for the first year and 7.5% for the second year. 
The adjusted risk reduction for teriflunomide 14 mg vs placebo in the fixed two-year 
duration TEMSO study was 31.5%, and 36% in the variable duration TOWER study. An 
integrated analysis showed a pooled 34% reduction compared to placebo. A 33% reduction 
for ponesimod 20 mg compared to teriflunomide 14 mg gives a relative 55% reduction 
compared to placebo, similar to that observed in the fingolimod Phase 3 trials. The 
dispersion from the ponesimod Phase 2 study was 1.0; the calculated dispersion from the 
TEMSO study is 0.8, so the chosen dispersion is the mean of the two. 
11.5.2 Secondary endpoints 
Keeping the sample size fixed at 550 subjects per treatment group, the power to detect 
clinically meaningful treatment effects for the secondary endpoints is shown below. 
No power was calculated for FSIQ-RMS or Time to 24-week CDA. 
11.5.2.1 Cumulative number of CUAL 
Assuming 1.5 CUAL per year for teriflunomide, a reduction of 33% for ponesimod and a 
dispersion of 3.65 will give an approximate power of 80% for a two-sided local 
significance level of 0.05/3. If, within the fallback procedure, alpha can be passed on to the 
hypothesis on CUAL a local two-sided significance level of 0.05/3*2, results in a power 
of 86%. Dropout rates as for the primary endpoint have been assumed. 
11.5.2.2 Time to 12-week CDA 
Assuming a 12-week CDA rate at 2 years for teriflunomide 14 mg of 16% and a hazard 
ratio of 0.67 (i.e., 2-year progression of 11% for ponesimod 20 mg), this gives with a 
sample size of 1100 an approximate power of 45% for a two-sided local significance level 
of 0.05/3. If, within the fallback procedure, alpha can be passed on to Time to 12-week 
CDA a local two-sided significance level of 0.05/3*2 (~0.033) or 0.05 can be used resulting

in a power of approximately 56% or 62%, respectively. Dropout rates as for the primary 
endpoint have been assumed.  
11.5.3 Sample size sensitivity 
Increasing the ARR for ponesimod to 0.223 (which corresponds to a risk reduction of 30%) 
decreases the power to approximately 80%. If the ARR is 10% lower than assumed in both 
ponesimod 20 mg (ARR = 0.194) and teriflunomide 14 mg (ARR = 0.288), the power 
reduces to approximately 87%.  
11.5.4 Sample size re-estimation 
There is no sample-size re-estimation planned. 
11.5.5 Other sample size considerations 
The sample size necessary for the confirmation of minimal change thresholds for 
identifying responders on the FSIQ-RMS symptom scale is based on psychometric 
analyses, which will be performed using data from the FMS. 
For confirmation, as a preliminary analysis, these thresholds will be evaluated using 
blinded data collected within the Phase 3 clinical trial (AC-058B301) on a subset of 
subjects with available data on the FSIQ-RMS, the PGI-S of Fatigue and the CGI-C 
(in MS) between baseline and Week 108. 
Using data collected within a non-interventional observational study, preliminary 
thresholds were calculated using two anchors: 1) patient-reported severity of fatigue as 
measured by the PGI-S of Fatigue with a mean improvement level of 6.19 and 2) clinician-
reported severity of MS as measured by the CGI-C with a mean improvement level of 
11.68. Given the consideration of these thresholds, it is necessary to identify the number 
of subjects required to detect the same level of change within the confirmatory Phase 3 
clinical trial. As the data will be blinded for this psychometric confirmatory analysis, power 
calculation based upon a paired t-test for mean difference between baseline and Week 108 
was conducted. 
Results from a statistical power analysis suggest that, in order to detect a −6.19 change 
from baseline in FSIQ-RMS Symptoms score (assumed baseline standard deviation  
= 24.1), an N of approximately 98 subjects demonstrating change would be necessary to 
obtain statistical power at a recommended 0.90 level. For the −11.68 change from baseline 
in FSIQ-RMS Symptoms score (assumed baseline standard deviation = 24.1), an N of 
approximately 29 subjects demonstrating change would be necessary to obtain statistical 
power at a recommended 0.90 level.  
In an observational study with MS patients over 13 weeks where the FSIQ-RMS was 
administered, 27% of the patients indicated no change in their fatigue level, 43% improved 
in a meaningful way on the PGI-S of Fatigue, and the remaining 30% worsened. If this

information is applied to the power calculation for the blinded analysis set, the sample size 
needs to be increased to 228 subjects (98 would demonstrate an improvement, 130 subjects 
would not change or deteriorate and could therefore not be used for the analysis). 
Furthermore, adjusting for a drop-out rate of 15% and 7.5% for Year 1 and Year 2, 
respectively, leads to a sample size of 291 subjects for the blinded responder threshold 
analysis. 
12 DATA HANDLING 
12.1 Data collection 
The investigator/delegate is responsible for ensuring the accuracy, completeness, and 
timeliness of the data reported. All source documents should be completed in a neat, legible 
manner to ensure accurate interpretation of the data. Data reported in the eCRF derived 
from source documents must be consistent with the source documents. 
eCRF data will be captured via electronic data capture (EDC using the Rave system 
provided by Medidata Solutions, Inc., a web-based tool). The investigator and site staff 
will be trained to enter and edit the data via a secure network, with secure access features 
(username, password and identification – an electronic password system). A complete 
electronic audit trail will be maintained. The investigator/delegate will approve the data 
(i.e., confirm the accuracy of the data recorded) using an electronic signature (refer to 
21 CFR Part 11). In addition to the main eCRF, a separate eCRF will be used to collect 
data with unblinding potential generated on Day 1 and on the first day of re-initiation of 
study drug when post-dose monitoring is required. This data will only be visible to the site 
monitor, the first-dose monitor and to an Independent Data Management Team 
[see Sections 5.1.5.2 and 10.1.5]. 
Entries recorded by the subject in the electronic device (FSIQ-RMS, PGI-S of Fatigue, 
SF-36v2TM, MS Patient Preference Questionnaire, and WPAI:MS) and the eC-SSRS are 
considered source data. The site staff will review and ensure completeness and readability 
(if applicable) of the subject’s entries. 
Subject screening and enrollment data will be completed for all subjects (i.e., eligible and 
non-eligible) through the IRT system and eCRF. 
For each subject enrolled, regardless of study treatment initiation, an eCRF must be 
completed and signed by the investigator/delegate. This also applies to those subjects who 
fail to complete the study. If a subject withdraws from the study, the reason must be noted 
on the eCRF.

12.2 Maintenance of data confidentiality 
The investigator/delegate must ensure that data confidentiality is maintained. On CRFs or 
other documents submitted to Actelion, subjects must be identified only by number and 
never 
by 
name 
or 
initials, 
hospital 
numbers 
or 
any 
other 
identifier. 
The investigator/delegate must keep a subject identification code list at the site, showing 
the randomization number, the subject’s name, date of birth and address or any other 
locally accepted identifiers. Documents identifying the subjects (e.g., signed ICFs) must 
not be sent to Actelion, and must be kept in strict confidence by the investigator/delegate. 
12.3 Database management and quality control 
Electronic CRFs will be used for all subjects. The investigator will have access to the site 
eCRF data until the database is locked. Thereafter, they will have read-only access. The 
eCRF must be kept current to reflect subject status at any timepoint during the course of 
the study. 
While entering the data, the investigator/delegate will be instantly alerted to data queries 
by validated programmed checks. Additional data review will be performed by Actelion 
on an ongoing basis to look for unexpected patterns in data and study monitoring. If 
discrepant data are detected, a query specifying the problem and requesting clarification 
will be issued and visible to the investigator/delegate via the eCRF. All electronic queries 
visible in the system either require a data correction (when applicable) and a response from 
the investigator/delegate to clarify the queried data directly in the eCRF, or simply a data 
correction in the eCRF. The investigator/delegate must, on request, supply Actelion with 
any required background data from the study documentation or clinical records. This is 
particularly important when errors in data transcription are suspected. In the case of health 
authority queries, it is also necessary to have access to the complete study records, provided 
that subject confidentiality is protected. 
This process will continue until database closure. 
Laboratory samples, ECGs, spirometry, eDiary, PGI-S of Fatigue, MS Patient Preference 
Questionnaire, SF-36v2TM, FSIQ-RMS, eC-SSRS, and WPAI:MS assessments will be 
processed centrally through their respective central laboratory/provider, and the results will 
be sent electronically to Actelion. If local laboratory data is obtained as may be required 
per protocol in certain instances, it must be entered in the eCRF by the site.  
After the database has been declared complete and accurate, the database will be closed. 
Any changes to the database after that time may only be made as described in the 
appropriate SOP. After database closure, the investigator will receive the eCRF of the 
subjects of her/his site (including all data changes made) on electronic media or as a paper 
copy.

13 PROCEDURES AND GOOD CLINICAL PRACTICE 
13.1 Ethics and Good Clinical Practice 
Actelion and the investigators will ensure that the study is conducted in full compliance 
with ICH-GCP guidelines, the principles of the “Declaration of Helsinki” and with the laws 
and regulations of the country in which the research is conducted.  
13.2 Independent Ethics Committee / Institutional Review Board 
The investigator will submit this protocol and any related document provided to the subject 
(such as Subject Information Leaflet used to obtain informed consent) to an IRB or IEC. 
Approval from the committee must be obtained before starting the study, and must be 
documented in a dated letter to the investigator, clearly identifying the study, the 
documents reviewed, and the date of approval.  
Modifications made to the protocol after receipt of the approval must also be submitted as 
amendments by the investigator to the IRB/IEC in accordance with local procedures and 
regulations [see Section 13.6]. 
A list of members participating in the IRB/IEC meetings must be provided, including the 
names, qualifications and functions of these members. If that is not possible, the attempts 
made to obtain this information along with an explanation as to why it cannot be obtained 
or disclosed must be documented in the study documentation. If a study staff member was 
present during a meeting, it must be clear that this person did not vote. 
13.3 Informed consent 
It is the responsibility of the investigator/delegate to obtain informed consent according to 
ICH-GCP guidelines and local regulations from each individual participating in this study 
and/or legal representative. The investigator/delegate must explain to subjects that they are 
completely free to refuse to enter the study or to withdraw from it at any time for any 
reason. 
The ICF will be provided in the country local language(s). 
Site staff authorized to participate in the consent process and/or to obtain consent from the 
subject and/or legal representative will be listed on an Actelion Delegation of Authority 
form. A study physician must always be involved in the consent process.  
The subject and/or legal representative must sign, personally date and time (if appropriate) 
the ICF before any study-related procedures (i.e., any procedures required by the protocol) 
begin. The ICF must also be signed, personally dated and timed (if the first study-mandated 
procedure was performed on the same day informed consent was obtained) by the 
authorized site staff listed on the Actelion Delegation of Authority form.

A copy of the signed and dated ICF is given to the subject and/or legal representative; the 
original is filed in the site documentation.  
The informed consent process must be fully documented in the subject’s medical records, 
including study reference, subject number, date/time (if applicable) when the subject was 
first introduced to Actelion clinical study, date/time (if applicable) of consent, who 
participated in the consent discussion, who consented the subject and any additional person 
present during the consent process (e.g., subject family member), copy of the signed ICF 
given to the subject / legal representative. 
13.4 Compensation to subjects and investigators 
Actelion provides insurance in order to indemnify (with both legal and financial coverage) 
the investigator/site against claims arising from the study, except for claims that arise from 
malpractice and/or negligence. 
The compensation of the subject in the event of study-related injuries will comply with 
applicable regulations. 
13.5 Protocol adherence/compliance 
The investigator must conduct the study in compliance with the approved version of the 
protocol and must not implement any deviation/change from the protocol, except when 
deviation is necessary to eliminate an immediate hazard to the subject.  
If a protocol deviation occurs, the investigator/delegate will inform Actelion or its 
representative, in a timely manner. The investigator/delegate must document and explain 
any deviation from the approved protocol. IRB/IEC and regulatory authorities must be 
informed, according to their requirements, but no later than 15 calendar days after the 
event. 
13.6 Protocol amendments 
Any change to the protocol can only be made through a written protocol amendment. 
A protocol amendment must be submitted to an IRB/IEC and regulatory authorities, 
according to their requirements. 
13.7 Essential documents and retention of documents 
The investigator/delegate must maintain adequate records necessary for the reconstruction 
and evaluation of the study. A number of attributes are considered of universal importance 
to source data and the records that hold those data. These include that the data and records 
are accurate, legible, contemporaneous, original (or certified copy), attributable, complete, 
consistent, enduring and available when needed.

These records are to be classified into two different categories of documents: investigator’s 
file, and subject clinical source documents.  
These records must be kept by the investigator for as long as is necessary to comply with 
Actelion’s requirements (e.g., as specified in the clinical study agreement), and national 
and/or international regulations, whichever would be the longest period. If the investigator 
cannot guarantee this archiving requirement at the investigational site for any or all of the 
documents, special arrangements respecting the data confidentiality must be made between 
the investigator and Actelion to store these documents outside the site, so that they can be 
retrieved in case of a regulatory inspection. No study document should be destroyed 
without prior written approval from Actelion. Should the investigator wish to assign the 
study records to another party or move them to another location Actelion must be notified 
in advance.  
If the site is using an electronic/computerized system to store subject medical records, it 
can be used for the purpose of the clinical study if it is validated (as per 21 CFR Part 11 or 
equivalent standard) and if the monitor has been provided personal and restricted access to 
study subjects only, to verify consistency between electronic source data and the eCRF 
during monitoring visits. 
If the site is using an electronic/computerized system to store subject medical records but 
it could not be confirmed that the system is validated or if the monitor could not be provided 
access to the system, the site is requested to print the complete set of source data needed 
for verification by the monitor. The print-outs must be numbered, stapled together with a 
cover sheet, signed and dated by the investigator/delegate to confirm that these certified 
copies are exact copies having the same information as the original subject’s data. The 
printouts will be considered as the official clinical study records and must be filed either 
with the subject medical records or with the subject’s eCRF.  
In order to verify that the process the site uses to prepare certified copies is reliable, the 
monitor must be able to observe this process and confirm that the comparison of the source 
documents and the certified copy did not reveal inconsistencies. The monitor does not need 
to verify this process for all data of all subjects but at least for some of them (e.g., first 
subject, regular check during the study of critical data like inclusion/exclusion criteria, 
endpoints for some subjects) as per Actelion’s instructions. If it were not possible for the 
monitor to observe this process, it would not be possible to rely on the site’s certified copies 
and therefore the site cannot be selected for the clinical study. The printouts should be filed 
either with the subject medical records or with the subject’s eCRF.

13.8 Monitoring 
Prior to study start, a site initiation visit (SIV) will be performed after the required essential 
study documents are approved by Actelion. The study treatment will be shipped to the site 
upon approval of the required essential documents.  
The principal investigator must ensure that all site personnel involved in the study will be 
present during the SIV and will dedicate enough time to it. Site information technology 
support should also be available during the initiation visit.  
The SIV must be completed before the site can start the screening of study subjects. 
Following the SIV, a copy of the completed initiation visit report and FU letter will be 
provided to the principal investigator and filed in the ISF. 
During the study, the monitor will contact and visit the investigational site regularly, and 
on request must be permitted to have access to trial facilities and all source documents 
needed to verify adherence to the protocol and the completeness, consistency and accuracy 
of the data being entered in the CRFs and other protocol-related documents. Actelion 
monitoring standards require full verification that informed consent has been provided, and 
verification of adherence to the inclusion/exclusion criteria, documentation of SAEs, and 
the recording of the main efficacy, safety and tolerability endpoints. Additional checks of 
the consistency of the source data with the CRFs will be performed according to the study-
specific monitoring plan. The frequency of the monitoring visits will be based on subject 
recruitment rate and critical data collection times. 
The principal investigator and first-dose administrator must ensure that the eCRF is 
completed after a subject’s visit to the site, and that all requested subject files (e.g., ICFs, 
medical notes/charts, other documentation verifying the activities conducted for the study) 
are available for review by the monitor. The required site personnel must be available 
during monitoring visits and allow adequate time to meet with the monitor to discuss study-
related issues.  
The investigator agrees to cooperate with the monitor(s) to ensure that any issues detected 
in the course of these monitoring visits are resolved. If the subject is hospitalized or dies in 
a hospital other than the study site, the investigator is responsible for contacting that 
hospital in order to document the SAE, in accordance with local regulations. 
A close-out visit will be performed for any initiated site and when there are no more active 
subjects and after all study data have been accepted by medical review and all FU issues 
have been resolved. In case a site does not enroll any subjects, the close-out visit may be 
performed prior to study database closure at the discretion of Actelion.

13.9 Investigator site file 
Each site will be provided with an ISF prior to the initiation visit. It will contain all the 
essential documents that are required to always be up-to-date and filed at site as per ICH 
GCP section 8. 
The ISF will include a table of contents listing the essential documents. All study related 
documentation must be maintained in the ISF. 
In some cases, exceptions can be discussed with the monitor regarding the filing of the 
study documents outside the ISF. It should be clearly documented where each document is 
filed. This note to file should be present in the specific tab of the document in the ISF. 
The ISF must be stored in a secure and access-restricted area during and after the study. 
It must be kept by the site for as long as needed to comply with any applicable rules and 
regulations, ICH-GCP as well as instructions from Actelion. If the site needs to transfer the 
ISF to another location and/or if the site facility can no longer store the ISF, the principal 
investigator must inform Actelion immediately.  
If the principal investigator will change, or if the site will relocate, the monitor must be 
notified as soon as possible.  
13.10 Audit 
Actelion’s Global Quality Management representatives may audit the investigator site 
(during the study or after its completion). The purpose of this visit will be to determine the 
investigator’s adherence to ICH-GCP, the protocol, and applicable regulations; adherence 
to Actelion’s requirements (e.g., SOPs) will also be verified. Prior to initiating this audit, 
the investigator will be contacted by Actelion to arrange a time for the audit.  
The investigator and staff must cooperate with the auditor(s) and allow access to all study 
documentation (e.g., subject records) and facilities. 
13.11 Inspections 
Health authorities and/or IRBs/IECs may also wish to conduct an inspection of Actelion’s 
clinical study (during the study or after its completion).  
Should an inspection be requested by a health authority and/or IRB/IEC, the investigator 
must inform Actelion immediately (usually via the monitor) that such a request has been 
made.  
The investigator and staff must cooperate with inspector(s) and allow access to all study 
documentation (e.g., subject records) and study facilities.

13.12 Reporting of study results and publication  
Study results will be documented in a clinical study report that will be signed by Actelion 
representatives and the coordinating investigator (or principal investigator for single-center 
studies). 
Separate reports are planned for the final analyses of PK data, the MRI sub-study, and the 
Patient Preference sub-study.  
The coordinating investigator and the steering committee / advisory board, if any, will have 
the opportunity to review the analysis of the data and to discuss the interpretation of the 
study results with Actelion prior to publication. 
Actelion will post results from its clinical studies on Actelion’s clinical trial disclosure 
system and on external/national registries, as required by law. 
Actelion’s policy on disclosure of clinical research information can be found at:  
http://www.actelion.com/documents/corporate/policies-charters/policy-clinical-research-
information.pdf 
In accordance with the Good Publication Practices and ethical practice, the results of the 
study will be submitted for publication in a peer-reviewed journal. Study results can be 
submitted for presentation at a congress before publication in a peer-reviewed journal. 
Authorship will be determined in accordance with the International Committee of Journal 
Editors criteria, and be based on: 
• Substantial contributions to: the conception or design of the study, or the acquisition, 
analysis or interpretation of data; and 
• Drafting of the publication or critical review for important intellectual content; and  
• Providing final approval of the version to be published; and 
• Agreement to be accountable for all aspects of the work in ensuring that questions 
related to the accuracy or integrity of any part of the work are appropriately investigated 
and resolved.  
The list of authors of any publication of study results may include representatives of 
Actelion and will be determined by mutual agreement. 
Any study-related publication written independently by investigators must be submitted to 
Actelion for review at least 30 days prior to submission for publication or presentation. 
Upon review, Actelion may provide comments and may also request alterations and/or 
deletions for the sole purpose of protecting its confidential information and/or patent rights. 
Neither the institution nor the investigator should permit publication during such a review 
period.

juxtacortical, infratentorial, or spinal cord); or 
Await a second clinical attacka implicating a different CNS site; and 
For dissemination in time (DIT): 
Simultaneous presence of asymptomatic gadolinium-enhancing and non-
enhancing lesions at any time; or  
A new T2 and/or gadolinium-enhancing lesion(s) on follow-up MRI, 
irrespective of its timing with reference to a baseline scan; or

Insidious neurological 
progression suggestive of 
MS (PPMS) 
1 year of disease progression (retrospectively or prospectively 
determined) plus 2 of 3 of the following criteriad: 
1. Evidence for DIS in the brain based on ≥ 1 T2 lesions in the 
MS-characteristic (periventricular, juxtacortical, or infratentorial) regions 
2. Evidence for DIS in the spinal cord based on ≥ 2 T2 lesions in the cord 
3. Positive CSF (isoelectric focusing evidence of oligoclonal bands and/or 
elevated IgG index) 
If the criteria are fulfilled and there is no better explanation for the clinical presentation, 
the diagnosis is ‘‘MS’’; if suspicious, but the Criteria are not completely met, the diagnosis 
is ‘‘possible MS’’; if another diagnosis arises during the evaluation that better explains the 
clinical presentation, then the diagnosis is ‘‘not MS.’’

historical, with duration of at least 24 hours, in the absence of fever or infection. It should 
be documented by contemporaneous neurological examination, but some historical events 
with symptoms and evolution characteristic for MS, for which no objective neurological 
findings are documented, can provide reasonable evidence of a prior demyelinating event. 
Reports of paroxysmal symptoms (historical or current) should, however, consist of 
multiple episodes occurring over not less than 24 hours. Before a definite diagnosis of MS 
can be made, at least 1 attack must be corroborated by findings on neurological 
examination, visual evoked potential response in subjects reporting prior visual 
disturbance, or MRI consistent with demyelination in the area of the CNS implicated in the 
historical report of neurological symptoms. 
bClinical diagnosis based on objective clinical findings for 2 attacks is most secure. 
Reasonable historical evidence for 1 past attack, in the absence of documented objective 
neurological findings, can include historical events with symptoms and evolution 
characteristics for a prior inflammatory demyelinating event; at least 1 attack, however, 
must be supported by objective findings. 
cNo additional tests are required. However, it is desirable that any diagnosis of MS be made 
with access to imaging based on these criteria. If imaging or other tests (for instance, CSF) 
are undertaken and are negative, extreme caution needs to be taken before making a 
diagnosis of MS, and alternative diagnoses must be considered. There must be no better 
explanation for the clinical presentation, and objective evidence must be present to support 
a diagnosis of MS. 
dGadolinium-enhancing lesions are not required; symptomatic lesions are excluded from 
consideration in subjects with brainstem or spinal cord syndromes. 
MS = multiple sclerosis; CNS = central nervous system; MRI = magnetic resonance 
imaging; DIS = dissemination in space; DIT = dissemination in time; PPMS = primary 
progressive multiple sclerosis; CSF = cerebrospinal fluid; IgG = immunoglobulin G.

Appendix 3 
Guidance for concomitant treatment with QT-prolonging drugs with 
known risk of Torsades de Pointes 
QT-prolonging medications with known risk of Torsades de Pointes (e.g., azithromycin, 
citalopram, clarithromycin, erythromycin, escitalopram, moxifloxacin, etc.) should be 
administered with caution since ponesimod may potentially enhance their effect on QT 
interval. A list of QT-prolonging medications with known risk of TdP is published by 
AZCERT [University of Arizona CERT http://crediblemeds.org/]. The investigator should 
also take into account other relevant risk factors such as hypokalaemia when considering 
treatment with a QT-prolonging drug. If treatment with such drugs is considered necessary, 
the principal investigator / treating neurologist should always discuss with the first-dose 
administrator and/or a cardiologist the appropriateness of combining such drugs with the 
study drug and may interrupt or permanently discontinue study drug. If the principal 
investigator determines in the best interest of the subject to concomitantly administer a QT-
prolonging drug with known risk of Torsades de Pointes the following recommendations 
must be adhered to:  
a) For a need to start treatment or to increase the dose of a QT-prolonging drug with known 
risk of Torsades de Pointes during the up-titration, treatment with study drug must be 
interrupted.  
• Study drug can only be re-initiated [see Section 5.1.10] after the QT-prolonging drug 
has been stopped or once the QT-prolonging drug has reached the steady state  
o Once the QT-prolonging drug has reached the steady state and prior to 
re-initiation of study drug, the QTcF interval obtained pre-dose on the day of 
the planned re-initiation must be ≤ 450 ms for males or ≤ 470 ms for females 
o Following re-initiation of study drug, at next visit (scheduled or unscheduled 
occurring after completion of the up-titration), perform ECG measurements 
pre-dose.  
b) For a need to start treatment or to increase the dose of a QT-prolonging drug with known 
risk of Torsades de Pointes during the study excluding the up-titration (i.e., after 2 weeks 
of study drug initiation or re-initiation).  
• At visit (scheduled or unscheduled) prior to initiation or dose increase of 
QT-prolonging drug with known risk of Torsades de Pointes, perform ECGs 
measurements pre-dose.  
o If prior to initiation or dose increase of QT-prolonging drug with known risk of 
Torsades de Pointes, the QTcF interval is > 450 ms for males or > 470 ms for 
females, treatment with study drug must be interrupted.

Appendix 6 
Abnormalities for ECG, BP and laboratory variables 
 
Notable abnormalities for ECG and BP that are related to the potential effects of ponesimod 
or teriflunomide will address the following variables: 
• Morphological ECG findings (defined as any abnormal finding not present prior to 
start of treatment). 
• HR outliers (bpm), based on ECG 
• PR interval (ms) 
• QT/QTc interval (ms), QTcB or QTcF 
• BP (mmHg) 
The definition of the abnormal values to be reported will be described in the SAP. 
Laboratory abnormalities 
Laboratory values below or above the normal range will be graded at three levels (H, HH, 
HHH for values above normal range and L, LL, LLL for values below the normal range) 
where L stands for “low”, H for “high”. 
The term “marked abnormality” describes laboratory values above or below the thresholds, 
with grading of abnormalities at two levels: LL/HH and LLL/HHH. These thresholds have 
been defined by the sponsor in order to flag and/or communicate abnormal laboratory 
results from the central laboratory to the investigators, and for the purpose of standardized 
data analysis and reporting by the sponsor. The definitions of marked abnormal values are 
based mainly on the Common Terminology Criteria for Adverse Events (CTCAE) 
[CTCAE 2010] grading system and, in specific cases (e.g., lymphocyte levels), are adjusted 
based on the known PD effect of the study drugs (e.g., LLL threshold for lymphocytes).  
The term ALERT here corresponds to protocol-defined test result threshold requiring an 
action from the investigator as described in the protocol (e.g., repeat the test; interrupt or 
discontinue the study drug) and should not be confused with the term “call alert” used by 
the central laboratory for laboratory results, which will be communicated to the 
investigator. Not all ALERTS listed in this table will be “call alerts” from the central 
laboratory and vice versa. 
PLEASE NOTE: Thresholds for abnormality of level L or H are not provided in this 
appendix but will be provided in the central laboratory manual. Parameters for which no 
threshold is defined in Table 8 below may be defined in the central laboratory manual.

Appendix 7 
Multiple Sclerosis Functional Composite 
The MSFC consists of the three following assessments: 
1) Timed 25-Foot walk;  
The Timed 25-Foot Walk is a quantitative measure of lower extremity function. It is the 
first component of the MSFC administered at each visit. The subject is directed to one end 
of a clearly marked 25-foot course and is instructed to walk 25 feet as quickly as possible, 
but safely. The task is immediately administered again by having the subject walk back the 
same distance. Subjects may use assistive devices when doing this task. In clinical trials, it 
is recommended that the treating neurologist select the appropriate assistive device for each 
subject. 
2) 9-Hole Peg Test (9-HPT);  
The 9-HPT is a quantitative measure of upper extremity (arm and hand) function. The 9-
HPT is the second component of the MSFC to be administered. Both the dominant and 
non-dominant hands are tested twice (two consecutive trials of the dominant hand, 
followed immediately by two consecutive trials of the non-dominant hand). It is important 
that the 9-HPT be administered on a solid table (not a rolling hospital bedside table) and 
that the 9-HPT apparatus be anchored. 
3) Paced Auditory Serial Addition Test (PASAT-3” version). 
The PASAT is a measure of cognitive function that specifically assesses auditory 
information processing speed and flexibility, as well as calculation ability. The PASAT is 
presented on audiocassette tape or compact disc to control the rate of stimulus presentation. 
Single digits are presented either every 3 seconds and the subject must add each new digit 
to the one immediately prior to it. The test score is the number of correct sums given (out 
of 60 possible) in each trial. To minimize familiarity with stimulus items in clinical trials 
and other serial studies, two alternate forms have been developed; the order of these should 
be counterbalanced across testing sessions. The PASAT is the last measure of the MSFC 
that is administered at each visit. 
Test administration: 
The MSFC should be administered as close to the beginning of a study visit as possible but 
definitely before the subject does a distance walk. MSFC components should be 
administered in the following order: 
1. Trial 1, Timed 25-Foot Walk 
2. Trial 2, Timed 25-Foot Walk

5. Trial 1, Non-Dominant Hand, 9-HPT 
6. Trial 2, Non-Dominant Hand, 9-HPT 
7. PASAT-3” 
Scoring: 
There are three components to the MSFC: (1) the average scores from the four trials on the 
9-HPT (the two trials for each hand are averaged, converted to the reciprocals of the mean 
times for each hand and then the two reciprocals are averaged); (2) the average scores of 
two Timed 25-Foot Walk trials; (3) the number correct from the PASAT-3. The MSFC is 
based on the concept that scores for these three dimensions – arm, leg, and cognitive 
function – are combined to create a single score (the MSFC) that can be used to detect 
change over time in a group of MS subjects. This is done by creating Z-scores for each 
component of the MSFC. 
MSFC Score = {Zarm, average + Zleg, average + Zcognitive} / 3.0 
Where Zxxx =Z-score

Appendix 8 
Symbol Digit Modalities Test 
The SDMT [Smith 1982, Benedict 2006] measures attention and processing speed much 
like the PASAT. The SDMT includes a reference key of 9 symbols, each paired with a 
single digit. Below the reference key are rows of the symbols arranged randomly. The 
subject is given 90 seconds to say the number that corresponds with each symbol. The test 
administrator records the answers and the number of correct answers is recorded as the 
score.  
The SDMT will be performed after the MSFC. Study personnel will be trained to 
administer and score the SDMT. A sample of the SDMT is provided below. Subjects will 
complete the test on a validated paper form that will be collected and transcribed in the 
eCRF.

Appendix 14 MS Patient Preference Questionnaire 
Questionnaire 
[Benefits of MS treatments] 
Patients with multiple sclerosis are prescribed medication to prevent new relapses, to 
increase the time until their MS gets worse, and to reduce the chance of disability due to 
disease progression. The following sections focus on your preferences for the benefits 
associated with some MS treatments.  
 
[Screen 1 - Number of Relapses] 
Relapsing MS (RMS), is the most common type of MS. Relapses are signs or symptoms 
from the central nervous system, (which consists of the brain, spinal cord and optic nerves) 
such as muscle weakness, tingling, double vision or dizziness, and are due to changes in 
the central nervous system due to inflammation which occurs in MS.  
Please use the ‘i’ button to see more information on relapses in MS.

[Screen 0 - Disability due to disease progression]  
The treatments in MS aim to reduce the progression from your current level of functioning 
to the next level of disability. The questions in this section relate to preventing a transition 
from one MS-related disability level to the next level (“worsening of MS”). Please tell us 
your preferences, independent of your current MS functioning level.

[Risks of MS treatments] 
Patients with multiple sclerosis are treated with drugs that may be associated with liver 
failure, serious infections or increased risk for cancer. For some of the MS drugs, increased 
monitoring in the hospital may be necessary after the first dose of the drug to ensure that 
quick medical help is available in case of important side effects. The following sections 
focus on your preferences for the risks associated with some MS treatments.

[Screen 1 - Liver Failure] 
Drugs for MS may interfere with the functioning of your liver and in rare cases lead to liver 
failure. The next section will ask you about the chance of liver failure (serious enough to 
require hospitalization or interruption of the MS treatment) within 10 years of treatment. 
Please use the ‘i’ button to see more information on liver failure related to MS treatment.

[Screen 1 - Cancer] 
Some MS drugs acting through the immune system may increase the risk of getting a 
malignant tumor (cancer). This can be a skin cancer, blood cancer or any other type of 
cancer. There is currently no evidence supporting such risk for the MS drugs used in this 
study but patients are being observed for development of cancer.
