Protocol Version 6.0 (26 April 2023)  
This amendment is substantial based on the criteria in Article 10(a) of Directive 2001/20/EC of 
the European Parliament and the Council of the European Union. 
Overall Rationale for the Amendment 
The primary purpose of this amendment is: 
• To reflect the recent update to the risk profile of evobrutinib (i.e. important identified risk of 
drug-induced liver injury) by adapting liver-related eligibility criteria, monitoring, and 
discontinuation criteria as well as language on tolerability and safety of evobrutinib across the 
protocol. 
• To allow participants to stay on blinded IMP after DBTP in a DBE period to delay the switch 
of participants naïve to evobrutinib treatment to the OLE period. This will also allow to generate 
additional data on efficacy and safety over an extended period of time.

Study Intervention Groups and Duration: The Treatment Period of up to 156 weeks (minimum 
24 weeks) will be preceded by a 4-week Screening Period (may be extended after discussion with 
the Medical Monitor but cannot exceed 12 weeks) and followed by a 4-week Safety Follow-up 
after treatment completion or early discontinuation.  
Transition Into the DBE Period 
Participants who complete the DBTP Period, or who are still under study treatment when the PA 
is triggered, will be considered completers and will be eligible to continue in the DBE Period for 
continuation of treatment as assigned at randomization. Those participants who have not reached 
the Week 156 visit when the PA is triggered, need to undergo an End-of-DBTP Visit, which is 
also their first visit in the DBE. Participants who do not wish to enter the DBE period will have a 
Safety Follow-up Visit occurring after the End-of-DBTP visit. 
Transition Into OLE Period 
Participants who complete the DBE period, or who are still under study treatment once the 
Sponsor– upon agreement with Health Authorities / Ethics Committees – will have notified sites 
(i.e. the OLE is open for enrollment), will be eligible for transition into the OLE period. 
Participants entering the OLE period need to undergo an End-of-DBE Visit, which is also their 
first visit in the OLE period. All participants previously treated with teriflunomide, or with an 
unknown exposure status, entering the OLE will be required to complete the AEP prior to 
dispensation of the IMP in the OLE period. Participants who do not wish to transition into OLE, 
will have a Safety Follow-up Visit after the End of the DBE Period. The treating physician may 
consider conducting the AEP for participants coming off the IMP and prior to initiation of 
alternative DMTs. 
Transition Into Long-term Follow-up Study (MS200527_0123, LONGEVO) 
Once the long-term follow-up study (MS200527_0123, LONGEVO) is open for enrollment (i.e., 
once the sponsor – upon agreement with Health Authorities / Ethics Committees – will have 
notified sites), participants of the OLE will switch into the long-term follow-up study at the nearest 
transition visit (at Weeks 24, 48, 72, or 96 of the OLE period). Participants who do not wish to 
transition into the long-term follow-up study, will have a Safety Follow-up Visit after the End of 
Treatment visit in the OLE Period. 
In case the long-term follow-up study is open for enrollment while participants are still under study 
treatment in the DBE period, they will be offered to transition into that study by default. For 
participants entering the long-term follow-up study, their last visit in the current study (i.e. 
End-of-DBE Visit) is also their first visit in the long-term follow-up study. Participants who do 
not wish to transition into the long-term follow-up study will have a Safety Follow-up Visit after 
the End-of-DBE Visit. 
Involvement of Special Committee(s): Yes. Independent Data Monitoring Committee, 
Hepatology Assessment Committee (HAC), Endpoint Adjudication Committee (for the DBTP and 
DBE Period), and Study Steering Committee.

Introduction  
Evobrutinib is a potent, orally administered, highly selective, irreversible inhibitor of BTK that is 
being developed for the treatment of RMS. 
Complete information on the chemistry, pharmacology, efficacy, and safety of evobrutinib is in 
the current Investigator’s Brochure. 
2.1 
Study Rationale  
The purpose of this study is to characterize the efficacy and safety of evobrutinib 45 mg 
administered orally twice daily versus teriflunomide (Aubagio®; 14 mg once a day orally) in 
participants with RMS. 
Evobrutinib inhibits activation of B cells via the B cell receptor. In addition, evobrutinib inhibits 
activation of myeloid cells by immune complexes via Fc receptors as well as the differentiation of 
proinflammatory macrophages. Thus, evobrutinib may be suitable for the treatment of MS. 
The main randomized, double-blind, placebo-controlled Phase II study of evobrutinib with a 
parallel, open label, active control group (dimethyl fumarate [Tecfidera®]), in patients with RMS 
to evaluate efficacy, safety, tolerability, PK, and biological activity (MS200527_0086) is 
completed; the OLE part of the study is ongoing. The study consisted of first a 24-week period, in 
which 267 participants were randomized to evobrutinib 25 mg once daily (n = 52), 75 mg once 
daily (n = 53), 75 mg twice daily (n = 54), dimethyl fumarate 240 mg twice daily (provided open 
label) (n = 54), or placebo (n = 54). Data from the first 24-weeks were analyzed for the primary 
analysis (PA). Following the 24-week period, all remaining participants continued to be treated 
for an additional 24-week period as follows: participants who received previously evobrutinib 
25 mg once daily, 75 mg once daily, 75 mg twice daily, or dimethyl fumarate, continued to be 
treated with their original treatment, and participants who received placebo for the first 24-weeks 
were switched to evobrutinib 25 mg once daily. Treatment assignment remained blinded with the 
exception of dimethyl fumarate which was open label throughout the study. The first 48 weeks 
analysis is referred to as the BEA. For the PA, efficacy analysis consisted of the comparison 
between the placebo and evobrutinib treatment groups. No formal comparison between the 
dimethyl fumarate and the evobrutinib treatment groups was performed for either the PA or the 
BEA. 
In the PA, the primary efficacy endpoint of the Phase II study was the total number of 
gadolinium-enhancing T1 lesions at Weeks 12, 16, 20, and 24. The primary efficacy analysis was 
a comparison of each evobrutinib dose arm versus placebo based on lesion rate (lesions per scan) 
ratio, adjusted for Baseline lesion activity. The primary endpoint of the study was met, and both 
evobrutinib 75 mg once daily (lesion rate ratio 0.30, 95% CI: 0.14, 0.63; p = 0.0015 [unadjusted], 
p = 0.046 [adjusted according to Hochberg]) and evobrutinib 75 mg twice daily (lesion rate ratio 
0.44, 95% CI: 0.21, 0.93; p = 0.0313 [unadjusted], p = 0.0648 [adjusted according to Hochberg]) 
were associated with a reduction in T1 Gd+ lesion rate compared to placebo (Montalban 2020).

The first key secondary endpoint was ARR at 24-weeks. A trend towards a reduction in ARR 
(unadjusted [95% CI]) was seen with evobrutinib 75 mg once daily (0.13 [0.03, 0.38]; p = 0.09) 
and evobrutinib 75 mg twice daily (0.08 [0.01, 0.30]; p = 0.06) versus placebo (0.37 [0.17, 0.70]), 
with evidence of a dose response (p = 0.014). 
In the BEA, results showed an unadjusted ARR at 48 weeks of 0.11 (95% CI: 0.04, 0.25) for 
evobrutinib 75 mg twice daily and 0.25 (95% CI: 0.12, 0.44) for evobrutinib 75 mg once daily 
indicating that the efficacy trend observed during the first 24-week period was sustained during 
the second 24-week period, with greater clinical sustained efficacy in the 75 mg twice daily group. 
The results of the Phase II OLE (cutoff 26 September 2019) indicate that the participants from the 
evobrutinib 75 mg twice daily arm had an ARR of 0.11, consistent with what was observed at the 
end of the main study (Week 48, cutoff 13 July 2018). 
Evobrutinib at 45 mg twice daily in the fed state is expected to be similar to the tested 75 mg twice 
daily dose in the fasted state based on the available exposure/response data (see Section 4.3). 
These results provide evidence of evobrutinib’s efficacy compared to placebo. Clinical 
development efforts in the MS indication will focus specifically on RMS, with potential expansion 
into progressive MS (and SPMS) with subclinical CNS inflammation. 
Reversible elevations in transaminases (ALT and AST) have been observed in participants 
randomized to evobrutinib in the RMS Phase II study (MS200527_0086). This finding, and the 
overall safety and risk-benefit assessment of evobrutinib are discussed further in Section 2.3 and 
Section 4.3. 
Taken together, efficacy and safety data from this study support progression into Phase III. 
Refer to the Investigator’s Brochure for further information about the nonclinical and clinical 
programs and Guidance for the Investigator. 
2.2 
Background  
Currently there is no cure for MS, but the course of the disease can be altered favorably with DMT 
with varying levels of efficacy, and distinct safety and tolerability profiles. Most active RMS 
patients initiate treatment with an interferon-beta or glatiramer acetate therapy. Oral DMTs 
including dimethyl fumarate and teriflunomide are also used as first-line agents. If responding 
suboptimally, patients can be treated with an alternative, second-line oral therapy such as 
cladribine and fingolimod, or infusion agents such as natalizumab and ocrelizumab. Generally, 
DMTs perceived to be more efficacious have also been shown to be associated with more 
significant adverse effects, ranging from serious infections (i.e., PML) to autoimmunity and 
cancer. Switching among these DMTs occurs primarily due to perceived lack of efficacy or the 
occurrence of AEs, as well as individual patient preferences. 
Despite the recent approvals of newer therapies for the treatment of MS, there remains an unmet 
need for highly effective and disease-modifying therapies that address not only inflammation but 
also disability progression within the CNS for patients with MS at all stages of the disease. Early 
treatment with a highly efficacious and safer DMT could be advantageous for long-term quality of

life for MS patients and might slow the process of brain atrophy, which accompanies axonal 
damage and loss of grey and white matter. 
Evobrutinib is a highly specific, oral inhibitor of BTK that inhibits B cell activation and 
B cell/T cell interaction, decreasing plasma cell formation and autoantibody production 
(Investigator Brochure, Haselmayer 2017). In addition, evobrutinib was shown to inhibit M1 
macrophage survival and proinflammatory cytokine release and promotes M2 polarization of 
reparative human monocytes in vitro (Alankus 2018). In line with the in vitro data, evobrutinib 
demonstrated pharmacological efficacy in both B cell and T cell dependent mouse models of MS, 
by reducing CNS inflammation and amelioration of disease severity (Boschert 2017, Torke 2018). 
Since B cell depletion studies have shown that antibody independent B cell functions play an 
important role in MS pathogenesis (Bar-Or 2010, Fraussen 2016, Jelcic 2018) and an altered innate 
immune system contributes to disability progression and repair in MS (Vogel 2013, Rawji 2016), 
evobrutinib may offer advantages over current approved DMTs. 
Clinical efficacy was recently demonstrated with B cell depleting anti-CD20 therapies in Phase II 
and Phase III clinical studies in RMS and progressive MS (Hauser 2008, Hawker 2009, 
Montalban 2016, Wolinsky 2016). Ocrelizumab (Ocrevus®) inhibited the formation of new 
inflammatory MRI lesions up to 90% (Hauser 2008) in Phase II RMS studies and high efficacy on 
MRI (-94%), ARR (-46%), and 24-week disease progression (-40%) was also reached in OPERA 
Phase I, II, and III studies against interferon-beta. Translational mechanism of action studies in 
anti-CD20 treated RMS patients show diminished proliferation and proinflammatory 
differentiation of T cells (Bar-Or 2010), pointing towards abrogation of antigen presenting cell 
function as the primary mechanism. In addition to the role of anti-CD20 in B cell antigen 
presentation, a recent publication of Li et al (Li 2015) describes a diminished proinflammatory 
myeloid cell response in ocrelizumab treated MS participants. Evobrutinib shows inhibition of 
myeloid cell activation by immune complexes. 
Preclinical proof of concept with evobrutinib has been demonstrated for SLE/lupus nephritis, 
experimental autoimmune encephalomyelitis, RA and passive cutaneous anaphylaxis. Oral 
evobrutinib does not deplete B cells in the studies carried out to date and, upon withdrawal, 
restoration of immune function can be achieved in days. This is less than treatment with anti-CD20 
therapies, where restoration of the immune system can take months, and is important should the 
need to interrupt or stop therapy arise. This suggests that a more favorable benefit to risk balance 
with respect to infections for evobrutinib versus anti-CD20 therapies may be observed. In addition, 
BTK inhibitors might have broader efficacy than agents that cause B cell depletion, due to the 
importance of BTK activation downstream of various receptors expressed in myeloid cells, 
suggesting an additional direct effect of evobrutinib on innate immune cell activation induced by 
immune complexes, cytokines/chemokines, or TLR activation (Block 2012, López-Herrera 2014, 
Whang 2014). A direct myeloid inhibition activity also best explains the significant reduction of 
clinical score, relapse rate, and time to first relapse in T cell dependent experimental autoimmune 
encephalomyelitis models, in which anti-CD20 antibodies do not work.

Benefit/Risk Assessment  
Benefit 
In the PA of the MS200527_0086 study, evobrutinib significantly decreased the number of T1 Gd+ 
lesions at Weeks 12, 16, 20, and 24 in participants with RMS. Similar to the relationship seen for 
the MRI endpoints, evobrutinib 75 mg once and twice daily was associated with a lower ARR 
compared to placebo. In the OLE, the ARR remained low and similar to those observed in the PA 
and BEA. These results show evobrutinib is efficacious in participants with RMS, and 
consequently warrant further investigation in Phase III clinical studies.  
Important Identified Risks 
As of July 2022, more than 2,490 participants in completed and ongoing clinical studies have been 
exposed to evobrutinib including healthy volunteers, participants with RMS, SLE, or RA, and 
participants with renal and hepatic impairment. The incidence of SAEs and TEAEs leading to 
withdrawal of study intervention was ≤ 10% in completed SLE, RA, or RMS studies. 
Overall, evobrutinib demonstrated manageable tolerability based on the completed and ongoing 
clinical studies across various indications. Observed TEAEs resolved after treatment 
discontinuation and did not result in permanent disabilities. In the ongoing blinded phase 3 studies, 
cases of DILI have been reported, which were typically asymptomatic and were resolving after 
drug discontinuation. The TEAEs have been primarily mild to moderate in severity.  
Important Potential Risk 
Important Potential Risk: Severe DILI, i.e. Requiring Transplant or Leading to Death 
Based on the important identified risk DILI, there is a theoretical consideration that evobrutinib 
may have the potential to cause severe DILI defined as liver organ failure, i.e. requiring transplant 
or leading to death. Hence, severe DILI, i.e., requiring transplant or leading to death is considered 
an important potential risk for evobrutinib. 
Important Potential Risk: Embryo-fetal Toxicity 
Embryo-fetal toxicity has been classified as an important potential risk based on nonclinical 
experience with evobrutinib (refer to IB), as well as other drugs in the same class. Results of 
nonclinical studies carried out in experimental models show that there is a risk of harm which 
could lead to increased rates of stillbirth, abortion, or cleft palate and limb deformities. While 
nonclinical data suggest no risk for male-mediated developmental effects, female participants of 
childbearing potential must use highly effective contraception and barrier method during the study 
and some period after the study is completed, as specified in the clinical study protocols.

first 12 weeks of DBTP and OLE, and every 2 weeks thereafter, for the first 6 months of exposure 
to evobrutinib. The protocol has strict stopping criteria for liver transaminase and total bilirubin 
elevations leading to treatment discontinuation and timely medical management. Also, relevant 
data will be reviewed by a Hepatology Assessment Committee (HAC) with appropriate expertise, 
which will report findings to the IDMC for consideration. 
Investigations on embryo-fetal development in toxicological studies showed an increased 
incidence of malformations (mainly cleft palate) and skeletal variations in mice when compared 
to the control group, and abortions and/or vaginal bleeding during the last period of gestation in 
rabbits. In addition, an increase of resorptions, and a lower mean fetal weight were also seen.  
Based on these investigations, embryo-fetal toxicity is considered as an important potential risk in 
participants exposed to evobrutinib. Therefore, female participants of childbearing potential must 
not be pregnant, must have a negative pregnancy test at the time of enrollment and use highly 
effective contraception (as specified in the clinical study protocol) during the study period and 
after the last dose, and should not donate eggs, as risk mitigation measures (for further details, see 
Section 5.1). 
Adverse Events of Special Interest 
Although no causal relationship has been established, AESIs including infections (serious and 
opportunistic infections), lipase and amylase elevation, and seizure, are under close monitoring.  
Due to the dominant role of CYP3A4/5 in the metabolism of evobrutinib, the compound may be a 
victim of DDI caused by inhibition (competitive/time-dependent) or induction of this enzyme by 
coadministered perpetrator drugs. The results of the completed clinical CYP DDI study 
(MS200527_0054) demonstrated that coadministration of evobrutinib with a moderate (e.g., 
fluconazole) or strong (e.g., itraconazole) CYP3A4 inhibitor resulted in a significant DDI. 
Evobrutinib peak and total exposures were increased by approximately 2.5- to 3.4-fold when 
evobrutinib was dosed concurrently with fluconazole or itraconazole. Based on these observations, 
the coadministration of medications that are moderate or strong inhibitors or inducers of 
CYP3A4/5 is not permitted during ongoing clinical studies. 
No new potential risks emerged from the completed studies: EMR200527_001, MS200527_0019, 
MS200527_0017, MS200527_0022, EMR200527_002, MS200527_0081, MS200527_0060, 
MS200527_0018, MS200527_0073, and MS200527_0074. 
Evobrutinib is a BTK inhibitor and, as such, works as an immunomodulator. There was some 
decrease in IgM, an increase in IgA, and IgG levels remained stable following treatment with 
evobrutinib. There was a decrease in CD19+ B cells and mature-naïve B cells, but no evidence of 
a change in memory B cell levels. The changes in B cells, IgA and IgM levels do not appear to be 
associated with an enhanced risk of infections, but the significance of these changes is not known 
(Montalban 2020). BTK is not required to clear viral infections, apart from enteroviruses. There is 
currently no evidence that evobrutinib treatment leads to a higher risk of SARS-CoV-2 infection, 
or a more severe disease. While no data regarding evobrutinib and COVID-19 are available, 
published data on approved BTK inhibitors (e.g., ibrutinib, acalabrutinib) used in oncology suggest

a protective effect of BTK inhibitors for severity and mortality of COVID-19 (Scarfò 2020, 
Thibaud 2020, Treon 2020).  
The evobrutinib data suggest that the risk of infections, including severe and opportunistic 
infections, is not higher than that observed with other disease-modifying treatments in MS, and no 
side effects have been identified that could exacerbate SARS-CoV-2 infection or mask COVID-19 
symptoms.  
Similarly, while teriflunomide is, like evobrutinib, an immunomodulatory agent, published reports 
of patients with MS and COVID-19 while on treatment with teriflunomide do not suggest an 
increased risk to patients, but rather a milder course of disease while on treatment (Ciardi 2020, 
Bollo 2020, Maghzi 2020, Möhn 2020). 
The recommendation by the Multiple Sclerosis International Federation is to continue 
disease-modifying treatment in MS to offset the risk of relapses, as the risk of disease rebound 
outweighs the risk of SARS-CoV-2 infection (MS International Federation 2020). 
To mitigate the risk of contracting COVID-19 during the study, there is flexibility in the timing of 
MRI assessments postscreening on a case-by-case basis. Safety labs, including liver function 
monitoring, may be collected during home visits, if available, and if permitted per local laws and 
regulations. 
In case a SARS-CoV-2 infection occurs during this study, interruption of the study treatment and 
treatment of COVID-19 are recommended as clinically indicated. After recovery, the continuation 
of the study will be at the Investigator’s discretion and in agreement with the medical monitoring 
team.  
The Sponsor will monitor the events related to any SARS-CoV-2 infection regularly. In addition, 
the IDMC will review the impact of any SARS-CoV-2 infection of a study participant as part of 
their activities and will provide recommendations, if required. 
Following the review of the totality of the safety data from the concluded clinical studies with 
evobrutinib, overall, evobrutinib was reported as well tolerated in patients with MS up to 75 mg 
twice daily. The safety profile of evobrutinib has been consistent across doses and indications. No 
dose-related relationship has been observed for the most frequently reported TEAEs. Furthermore, 
evobrutinib at 45 mg twice daily in the fed state is expected to be similar to the tested 75 mg twice 
daily dose in the fasted state based on the available exposure/response data (see Section 4.3). 
Benefit-Risk Conclusion 
Overall, considering the unmet medical need in MS patients, reduction of MS activities (decreased 
the number of T1 Gd+ lesions and lower ARR compared with placebo), convenience of an oral 
therapy and the measures put in place to mitigate the important identified and important potential 
risks, the benefit-risk of evobrutinib 45 mg twice daily fed supports continued clinical 
development of evobrutinib in this population. 
More detailed information about the known and expected benefits and risks and reasonably 
expected AEs of evobrutinib may be found in Section 4.2 and the Investigator’s Brochure. More

Study Design  
4.1 
Overall Design  
This is a Phase III, multicenter, randomized, parallel group, double-blind, double-dummy, 
active-controlled study of evobrutinib with an active control group teriflunomide, in participants 
with RMS. 
Eligible participants will be randomized 1:1 to treatment with evobrutinib 45 mg twice daily, or 
teriflunomide 14 mg once daily (oral), stratified by region and Baseline EDSS. Blinding will be 
accomplished using a double-dummy design. The total sample size is planned to be 898 
participants (approximately 449 participants per treatment group). 
The Treatment Period of up to 156 weeks (minimum 24 weeks) will be preceded by a 4-week 
Screening Period (may be extended after discussion with the Medical Monitor but cannot exceed 
12 weeks) and followed by a 4-week Safety Follow-up after treatment completion or early 
discontinuation. 
Transition Into the DBE Period 
Participants who complete the DBTP Period, or who are still under study treatment when the PA 
is triggered, will be considered treatment completers and will be eligible to continue in the DBE 
Period for continuation of treatment as assigned at randomization (Figure 2). Those participants 
who have not reached the Week 156 visit when the PA is triggered, need to undergo an End-of-
DBTP Visit, which is also their first visit in the DBE. Participants who do not wish to enter the 
DBE period will have a Safety Follow-up Visit occurring after the End-of-DBTP visit. 
Transition Into OLE Period 
Participants who complete the DBE period, or who are still under study treatment once the Sponsor 
– upon agreement with Health Authorities/Ethics Committees – will have notified sites (i.e. the 
OLE is open for enrollment), will be eligible for transition into the OLE period. Participants 
entering the OLE period need to undergo an End-of-DBE Visit which is also their first visit in the 
OLE period. All participants previously treated with teriflunomide, or unknown exposure status, 
entering the OLE will be required to complete the AEP prior to dispensation of the IMP in the 
OLE period. Participants who do not wish to transition into OLE, will have a Safety Follow-up 
Visit after the end of the DBE period. The treating physician may consider conducting the AEP 
for participants coming off the IMP and prior to initiation of alternative DMTs. 
Transition Into Long-term Follow-up Study (MS200527_0123, LONGEVO) 
Once the long-term follow-up study (MS200527_0123, LONGEVO) is open for enrollment (i.e. 
once the Sponsor – upon agreement with Health Authorities/Ethics Committees – will have 
notified sites), participants of the OLE will switch into the long-term follow-up study at the nearest

transition visit (at Weeks 24, 48, 72, or 96 of the OLE period). Participants who do not wish to 
transition into the long-term follow-up study, will have a Safety Follow-up Visit after the End of 
Treatment visit in the OLE period. 
In case the long-term follow-up study is open for enrollment while participants are still under study 
treatment in the DBE period, they will be offered to transition into that study by default. For 
participants entering the long-term follow-up study, their last visit in the current study (i.e. 
End-of-DBE Visit) is also their first visit in the long-term follow-up study. Participants who do 
not wish to transition into the long-term follow-up study will have a Safety Follow-up Visit after 
the End-of-DBE Visit.

Per Protocol Version 3, prior to the completion of enrollment, an optional IA for BSSR, based on 
12-week CDP (as measured by EDSS) data pooled from the present study and second Phase III 
study (MS200527_0082), was conducted. Based on this BSSR in August 2021, it was decided that 
the number of participants to be enrolled would not be increased. 
Initial enrollment was closed on 01 October 2021. The actual enrollment figures exceeded the 
original planned enrollment of 930 participants per study. 
The currently escalating crisis that erupted in Ukraine in February 2022, and the countries 
sanctioned as a result, pose a challenge to the successful conduct of the MS200527_0080 and 
MS200527_0082 studies due to the large representation of these countries in the initial enrollment. 
In the worst-case scenario, all data from participants in the regions affected by the crisis (Ukraine, 
Russian Federation, and Belarus) will be unable to be queried for cleaning purposes and will be 
considered unreliable for inclusion in the PA. The impact on study power is discussed in Section 
9.2.3.  
4.2 
Scientific Rationale for Study Design  
This study was designed to determine the efficacy and safety of evobrutinib in participants with 
RMS. The primary objective will focus on reduction of relapses relative to teriflunomide in adult 
participants with RMS based on the ARR up to 156 weeks.  
The findings in Section 2 support the pathogenic contribution of B cells to MS damage. In contrast, 
a failed clinical study with another B cell targeting agent, atacicept, supports the notion that certain

B cell subtypes may mediate beneficial anti-inflammatory effects (Kappos 2014). Novel 
nondepleting B cell therapies may deliver a more favorable benefit risk profile than current B cell 
directed therapeutic approaches. In the Phase II study of evobrutinib, the PA showed a clinically 
significant reduction in MRI activity in participants treated with evobrutinib compared to placebo. 
Furthermore, the results indicate that the ARR in the OLE remained low and similar to those 
observed in the PA and BEA. 
There is consensus in the MS community, that the use of placebo in Phase III studies with RMS 
participants is no longer ethical, due to the availability of established and effective therapies 
(Polman 2008). Teriflunomide is an acknowledged therapy that has recently been used in pivotal 
studies as a comparator and is well-suited for the objectives of this study. It is currently widely 
used in the treatment of MS and has a well-established efficacy and safety profile. Teriflunomide 
is administered as a tablet once daily and eliminates the burden of injections specific to other 
standard of care therapies such as interferons. For further information on teriflunomide, refer to 
the locally approved product information (e.g., relevant SmPC or USPI). 
The study will have a double dummy design, to minimize the potential for bias and maintain the 
integrity of the clinical data generated from this study. It also reduces the risk of concluding that 
superiority to the active comparator was driven by participant and assessor bias. 
This study plans to enroll RMS participants according to the McDonald MS 2017 criteria 
(Thompson 2018) with an EDSS score of 0 to 5.5 at Screening and Baseline (Day 1) who had at 
least one or more documented relapses within the 2 years before Screening with either: 
• one relapse which occurred within the last year prior to randomization, OR 
• the presence of at least 1 T1 Gd+ lesion within 6 months prior to randomization 
These criteria have been implemented to further characterize the benefits of treatment with 
evobrutinib in a wide range of RMS participants with varying degrees of disease activity and 
severity. The age range will be limited to ≤ 55 years with the aim to avoid confounding by 
neurological conditions prevalent in older participants. 
The proposed study endpoints are widely accepted as clinically relevant, and have been used in 
numerous pivotal clinical studies in RMS. The primary endpoint for the study will be ARR up to 
156 weeks, based on qualified relapses. Secondary efficacy endpoints will include time to 12- or 
24-week CDP (as measured by EDSS), total number of new or enlarging T2 lesions based on all 
available MRI scans, and total number of T1 Gd+ lesions based on all available MRI scans. 
Prevention of relapses, prevention/delay of accumulation of sustained neurological disability, as 
well as effect on MRI are meaningful goals in the treatment of participants with RMS. 
Time-to-24-week-CDI (as measured by EDSS) is a relatively new clinical endpoint 
complementary to the CDP endpoints. Week 12 NfL concentration is an emerging biomarker 
endpoint thought to reflect the early impact of treatment on reducing neuronal damage 
(Kuhle 2021; see Section 8.8.1.1 for details on NfL). The timepoint at Week 12 was chosen based 
on a post-hoc analysis of the data from a Phase II clinical study with evobrutinib.

Patient Reported Outcomes including those assessing fatigue and PF, are included as a secondary 
endpoint and several exploratory endpoints in the current study. Fatigue has been reported as the 
most bothersome symptom for MS patients among other concerns, such as bladder and bowel 
problems, cognitive impairment, visual disorders, musculoskeletal issues e.g., stiffness, spasm, 
walking difficulty and balance problems (Martin 2017, Patti 2011, Brañas 2000). In turn, these are 
associated with impairments in various functional areas, including IADLs, limitations with 
physical activities such as participating in sports, limitations related to ability to work or study, 
and social interactions (Patti 2014, LaRocca 2011). The current data from randomized controlled 
studies support positive treatment effects of currently available DMTs (including, teriflunomide, 
dimethyl fumarate, natalizumab, and ocrelizumab) on HRQoL, i.e., improving or preventing the 
worsening of HRQoL (Jongen 2017). 
Exploratory research of biomarkers of evobrutinib treatment response in MS aims to define 
responders and non-responders to therapy and to better understand disease pathology. Exploratory 
biomarkers will help to define an optimal evobrutinib treatment response in MS and thus be of 
considerable value for taking treatment decisions and ensuring continued benefit from evobrutinib 
therapy. As genetic variation may impact a participant’s response to therapy, susceptibility to 
disease, and severity and progression of disease, pharmacogenomic and pharmacogenetic 
biomarkers will be assessed to explore the long-term effect evobrutinib. In addition to this, blood 
sample assessments are included to test for biomarkers that are thought to play a key role in the 
disease pathology of MS and to be impacted by treatment with evobrutinib. 
The DBE and OLE periods have been introduced for participants completing the DBTP to enable 
an option for treatment continuation and to investigate sustained or long-term efficacy and safety 
of evobrutinib prior to enrollment in the long-term follow-up study. Refer to the Investigator’s 
Brochure for further information about the nonclinical and clinical programs and Guidance for the 
Investigator. 
4.3 
Justification for Dose  
Selection of the Phase III dose was based on PD, efficacy, and safety data from the Phase IIb study 
MS200527_0086, and supported by clinical pharmacology studies where dosing of the tablet was 
included (Studies MS200527_0017 and MS200527_0019). The models describing the exposure-
response relationship between PK and BTK occupancy (target engagement), ARR, number of T1 
Gd+ lesions and number of new or enlarging (active) T2 lesions (efficacy endpoints) were used in 
the selection of the dose. The results of the modeling of evobrutinib concentrations, BTK 
occupancy, ARR, T1 Gd+ and active T2 lesions were used to select the dose of 45 mg twice daily 
(fed) that will deliver efficacy anticipated to be better than 75 mg once daily (fasted) or equal to 
75 mg twice daily (fasted) observed in the RMS Phase IIb study. 
In the exposure-response analysis of Study MS200527_0086 for participants with RMS, a steep 
exposure-response curve was observed with a threshold evobrutinib exposure (AUC0-24,ss) of 
355 ng•h/mL associated with the onset of a reduction in ARR, and a significant reduction in ARR 
observed at evobrutinib exposure of ≥ 400 ng•h/mL. Participants with exposure ≤ 355 ng•h/mL 
had mean ARR values between 0.42 to 0.63, whereas participants with exposure > 355 ng•h/mL 
had mean ARR values between 0.00 to 0.14. The significant reduction in ARR was observed when 
trough BTK occupancy was > 95%, indicating high target engagement over the entire dosing

interval. In addition, for the participants with RMS and > 0 T1 Gd+ lesions at Baseline or > 13 cc 
T2 lesion volume at Baseline, a significant reduction in the number of T1 Gd+ lesions, and the 
number of active T2 lesions was observed when evobrutinib exposure was greater than 468 
ng•h/mL. This significant reduction in the number of active T2 lesions was observed when trough 
BTK occupancy was > 96%.  
Thus, the criteria for selection of an efficacious dose to be used in Phase III is based on targeting 
exposure of ≥ 468 ng•h/mL and with a high percentage of participants expected to have > 95% 
trough BTK occupancy. 
One dose of evobrutinib will be utilized in this study. A dose of 45 mg twice daily, when given 
with a meal, is expected to provide a (geometric) mean evobrutinib daily exposure (AUC0-24,ss) of 
840 ng•h/mL, with only 7.6% of the participants expected to have a daily exposure of < 400 
ng•h/mL. The 45 mg twice daily dose will be administered to participants with a meal, where food 
(either a high-fat or low/moderate-fat meal) has been shown to increase evobrutinib exposure by 
50%. Thus, the daily exposure with 45 mg twice daily fed is similar to the exposure observed in 
the Phase IIb study for 75 mg twice daily fasted (835 ng•h/mL), which provided a significant 
reduction in ARR (see Section 2.1). Mean Cmax,ss for 45 mg twice daily fed is expected to be 24% 
less (128 ng/mL) than the observed mean peak exposure (168 ng/mL) for 75 mg twice daily fasted. 
In addition, high BTK occupancy (at least 95% occupancy in 93% of the participants) is expected 
at the end of a dosing interval; therefore, similar efficacy to that of 75 mg twice daily (BTK 
occupancy of at least 95% in 92% of the participants). 
Teriflunomide will be administered orally at the highest approved dose of 14 mg once a day. Refer 
to the locally approved product information (e.g., relevant SmPC or USPI) for further details. 
Additional information about the justification for dose for evobrutinib may be found in the 
Investigator’s Brochure. 
4.4 
End of Study Definition  
A participant has completed the study if he/she has completed all study visits, including the last 
visit (as defined in the SoA in Section 1.3). A participant is considered a study completer if the 
participant has completed the Safety Follow-up Visit, even if the participant discontinued 
treatment prematurely. Treatment completers who do not require a Safety Follow-up Visit per 
protocol are also considered study completers (i.e., participants entering the long-term follow-up 
study at protocol-defined visits). 
• Treatment completion for the DBTP is defined as completing treatment up until the time of 
the PA trigger or 156 weeks post randomization, whichever is earliest.  
• Treatment completion for the DBE period is defined as completing treatment during the DBE 
at protocol-defined visits. 
• Treatment completion for the OLE period is defined as completing treatment during the OLE 
at protocol-defined visits. 
Refer to Section 9.4.4.2 for details on the PA.

5.5 
Lifestyle Considerations  
5.5.1 
Meals and Dietary Restrictions  
Refrain from consumption of Seville oranges, grapefruit or grapefruit juice, pomelos, grapefruit 
hybrids, exotic citrus fruits, cranberries, or their juices from 7 days before the start of study 
intervention until after the final dose (see Section 6.5.4). 
5.5.2 
Caffeine, Alcohol, and Tobacco  
During each dosing session, participants will abstain from alcohol for 24 hours before the start of 
dosing until after collection of the final PK and/or PD sample. Due to a potential for additive 
hepatotoxic effects associated with IMPs (teriflunomide and evobrutinib), alcohol consumption 
should be avoided during participation in the study. 
There are no restrictions on caffeine or tobacco intake. 
5.6 
Screen Failures  
Individuals who do not meet the criteria for participation in this study (screen failure) may be 
rescreened once with approval by the Medical Monitor. The second Screening Period is a new 28-
day Screening Period. This Screening Period may be extended after approval by the Medical 
Monitor (but cannot exceed 12 weeks) for the reasons described in Section 8. Rescreened

6.2 
Study Intervention(s) Preparation, Handling, Storage, and 
Accountability  
Storage 
All study intervention supplied to each site must be stored in their original containers carefully and 
safely. The storage facility at the study site must be locked and temperature controlled. Evobrutinib 
and its placebo must be stored at no more than 30°C (86°F). For teriflunomide and its placebo 
storage conditions, refer to the teriflunomide approved product label.  
In case there has been a temperature deviation at the clinical site, the site must contact the clinical 
research associate without delay for further evaluation and assessment by the designated quality 
assurance personnel at Merck Healthcare KGaA or delegated personnel at the packaging and 
distribution provider. The medication with the temperature excursion should still be stored at the 
required temperature, but quarantined during the investigations and must be appropriately labeled 
as “quarantine storage”. 
Detailed recommendations for the use of teriflunomide are described in the locally approved 
product information (e.g., relevant SmPC or USPI), as appropriate. 
The preparation, handling and storage of the study interventions will be documented in a separate 
Pharmacy Manual. 
The Investigator, institution, or the head of the medical institution (where applicable) is responsible 
for study intervention accountability, reconciliation, and record maintenance (i.e., receipt, 
reconciliation, and final disposition records). 
• Upon receipt of the study intervention(s), the Investigator or designee must confirm 
appropriate temperature conditions have been maintained during transit and any 
discrepancies are reported and resolved before use. Also, the responsible person will 
check for accurate delivery. Further guidance and information for study intervention 
accountability are provided in the Pharmacy Manual. 
• Only participants enrolled in the study may receive study intervention(s) and only 
authorized site staff may supply it. All study intervention(s) must be stored in a secure, 
environmentally-controlled, and monitored (manual or automated) area, in accordance 
with the labeled storage conditions, and with access limited to the Investigator and 
authorized site staff. 
• Dispensing will be recorded on the appropriate accountability forms so that accurate 
records will be available for verification at each monitoring visit. 
• Study intervention(s) accountability records at the study site will include the following: 
o Confirmation of receipt, in good condition and in the defined temperature range. 
o The inventory provided for the clinical study and prepared at the site. 
o The dose(s) each participant used during the study. 
o The disposition (including return, if applicable) of any unused study intervention(s).

o Dates, quantities, batch numbers, container numbers, expiry dates, and the 
participant numbers. 
• The Investigator site will maintain records, which adequately documents that 
participants were provided the doses specified in this protocol, and all study 
intervention(s) provided were fully reconciled. 
• Unused study intervention(s) must not be discarded or used for any purpose other than 
the present study. No study intervention that is dispensed to a participant may be 
redispensed to a different participant. 
• A Study Monitor will periodically collect the study intervention(s) accountability forms. 
• Further guidance and information for the final disposition of unused study 
intervention(s) are provided in the Pharmacy Manual. 
6.3 
Measures to Minimize Bias: Study Intervention Assignment 
and Blinding  
6.3.1 
Study Intervention Assignment  
Participants will be randomized in a blinded fashion to either evobrutinib or teriflunomide 
treatment in a 1:1 ratio. The randomization will be stratified by 2 factors: region (4 levels: North 
America, Western Europe, Eastern Europe, Rest of World) and Baseline (Day 1) EDSS (2 levels: 
< 4.0, ≥ 4.0). A unique participant identification number, assigned according to the Pharmacy 
Manual, will be used throughout the study. 
 
Study using IWRS 
After confirmation of participant’s eligibility and at the last practical 
moment prior to study intervention administration, participants will 
be centrally allocated to either evobrutinib or teriflunomide in a 1:1 
ratio using an IWRS and per a computer-generated randomization 
list. 
The IWRS will be used to assign unique participant numbers, 
allocate participants to study intervention group at the randomization 
visit, and study intervention to participants at each study intervention 
visit. 
Before the study is initiated, the log in information and directions for 
the IWRS will be provided to each site. The site will contact the 
IWRS prior to starting study intervention administration for each 
participant.

92/262 
 
 
6.3.2 
Blinding  
Blinding Method 
• Study intervention assignment will be randomized and blinded. Blinding will be accomplished 
using a double dummy design given the differences in tablet characteristics between the study 
intervention and the active control. 
• Packaging and labeling will be prepared to protect the blinded nature of the study. Study 
interventions will be provided in a manner that participants or Investigator will not be able to 
distinguish active study intervention from placebo. Each kit will be labeled by the manufacturer 
with a unique kit number; labeling will not indicate whether the medication is study intervention 
(evobrutinib/teriflunomide) or placebo. Blinded treatment kit numbers will be obtained through 
the IWRS. 
• The Treating Investigator is a neurologist and will be the only one to discuss signs and 
symptoms with the participant to prevent unblinding of study personnel, based on associated 
clinical signs and symptoms related to study intervention. The Treating Investigator will be 
blinded to study intervention and will be responsible for: 
o Management of the routine neurological care of the participant, including the 
management of background treatment and associated safety monitoring  
o Assessment (including assignment of causality) and treatment of AEs and MS 
relapses  
o Review of hematology and blood chemistry results from the central laboratory to 
assess whether the participant’s study intervention should be discontinued as per 
the criteria detailed in Section 7.1 
o If the Treating Investigator is not able to perform the C-SSRS and/or HRU tasks, 
they can assign these tasks to a non-neurologist delegate (Treating Investigator 
Designee), as long as the delegate is trained and qualified in performing these tasks. 
• The independent Examining Investigator (assessor) (or their Qualified Examining Designee) 
will perform neurological assessments only, will remain blinded to all study interventions 
(evobrutinib and teriflunomide), all other study-related assessments, and to all laboratory results 
throughout the study. 
• The central MRI reader will be blinded to all study interventions (evobrutinib and 
teriflunomide) throughout the study. 
• The participants, site staff, and the Investigator will be blinded to all study interventions 
throughout the DBTP and the DBE periods. 
• The Contract Research Organization and Sponsor will be blinded to all study interventions until 
the database is locked for the PA (see Section 9.4). 
• Importantly, the Treating Investigator (or designee) and the Examining Investigator (or 
designee) cannot perform the same tests. The Treating Investigator (or designee) performs the 
relapse assessments, AEs, monitors the participant, and performs C-SSRS and is not permitted 
to perform the EDSS, T25-FW, 9-HPT, and SDMT, and vice-versa, in order to maintain the 
blind. The Patient Reported Outcomes: PROMIS (physical function and fatigue), EQ-5D-5L

and SF-36v2 can be administered by any site personnel. Study participants will be instructed to 
not discuss AEs, signs, and/or symptoms with the independent Examining Investigator 
(assessor) (or designee). 
• The participants, site staff, and the Investigators will remain blinded to all study interventions 
during the Safety Follow-up. 
• The IDMC and supporting independent statistician will be unblinded to treatment, as described 
in the IDMC charter. 
• The bioanalytical monitors and other study team members responsible for analyses of PK will 
be blinded to study treatment codes prior to database lock for the PA. Analytical laboratories 
will be unblinded to study treatment codes to enable sample testing of study intervention prior 
to database lock. The process by which masked participant identifiers will be used to prevent 
linking PK data with other clinical data will be documented.  
• Subject matter experts and other study team members responsible for analyses of PGx will be 
blinded to study treatment codes prior to database lock for the PA. Analytical laboratories may 
be unblinded to study treatment codes to enable study-treatment-specific PGx testing prior to 
database lock for the PA. If study treatment specific PGx testing is performed, the process by 
which masked participant identifiers are used to maintain blinding will be documented.  
• Study intervention information that would unblind the study participants will not be reported 
with participant identifiers to investigative sites or blinded personnel until the study has been 
unblinded. 
• All other staff, other than those identified above, will remain blinded to the evobrutinib and 
teriflunomide study interventions. 
• Only when the last participant completes study intervention up to the PA trigger or a maximum 
of 156 weeks, or discontinues study intervention prematurely, the protocol deviations are 
determined, and the database is locked for the PA, will the drug codes be broken and made 
available for the data analysis. At that point, the Contract Research Organization and Sponsor 
study teams will be unblinded to study intervention, while the PI and study personnel remain 
blinded to the study intervention throughout the DBE. 
• All breaks of the study blind must be adequately documented.  
6.3.3 
Emergency Unblinding  
In an emergency, the Investigator is solely responsible for determining if unblinding of a 
participant’s study intervention assignment is warranted. Participant safety must always be the first 
consideration in this decision. The Sponsor must be notified within 24 hours after unblinding. The 
Investigator must provide the Sponsor the reason for unblinding without revealing the study 
intervention, except to the designated global patient safety representative via the Emergency 
Unblinding Notification Form. The date of and reason for unblinding must be recorded in the 
source documents and CRF. Contact information for unblinding in an emergency is given on the 
participant emergency card provided to each participant, as noted in Appendix 2 (Study 
Governance).

94/262 
 
 
The Sponsor’s global patient safety department will submit any SUSAR reports to regulatory 
authorities and ethics committees with unblinded information, per applicable regulations. Only 
blinded information will be provided to the study team. 
6.4 
Study Intervention Compliance  
The study intervention will be administered at the site on study visit days as defined in the SoA 
(see Section 1.3). All other administrations of study intervention will be done by the participant or 
participant’s caregiver at home throughout the rest of the study. Participants or participant’s 
caregiver will be asked to record the date and time of dosing and food intake around dosing (food 
intake to be recorded only on the day prior to PK sampling and the day of PK sampling, and around 
the time of the last dose prior to evobrutinib concentration assessment sampling) in a participant 
diary. 
Participants will be instructed to bring all study intervention, including the used packaging/empty 
boxes and all blisters, to each study visit during which IMP is dispensed as indicated in the SoA 
(see Section 1.3), and to allow for the assessment of compliance with study intervention. Prior to 
discharge from each scheduled visit, participants will be given sufficient study intervention for at-
home administration until the next scheduled visit during the Treatment Period. On study visit 
days during which IMP is dispensed as indicated in the SoA (see Section 1.3), the previous week(s) 
study intervention adherence will be documented using pill counts. 
Insufficient compliance with the protocol-specified dosing regimen is defined as receiving < 80% 
of the required number of scheduled doses of IMP. Noncompliance is further addressed in Sections 
7.1 and 8.4. 
6.5 
Concomitant Therapy  
Record in the CRF all concomitant therapies (e.g., medicines or nondrug interventions) used from 
the time the participant signs the informed consent until completion of the study, including any 
changes. For prescription and over-the-counter medicines, vaccines, vitamins, and herbal 
supplements, record the name, reason for use, dates administered, and dosing information. 
Contact the Medical Monitor for any questions on concomitant or prior therapy. 
Treatment for Symptoms of Multiple Sclerosis 
The Treating Investigator should attempt to maintain therapies or treatments for symptoms related 
to MS (e.g., walking ability, spasticity, incontinence, pain, fatigue) reasonably constant throughout 
the study. However, if such therapies need to be added or modified during the study due to changes 
in the participant’s clinical presentation, then this could be done at the discretion of the 
Investigator, with the exception of those treatments listed in Section 6.5.3 (Prohibited 
Medications). Nonetheless, any medications that are considered necessary for the participant’s 
well-being may be given at the discretion of the Investigator.

6.5.1 
Rescue Medicine  
Participants who experience a MS relapse during study intervention may receive rescue medication 
pursuant to the following restrictions:  
1. Up to 1 g daily of methylprednisolone administered intravenous (or orally if high-dose oral 
formulation is locally available) for up to 5 consecutive days. Where possible, the use of 
corticosteroids should be avoided in the 3 weeks prior to a scheduled MRI scan. If 
participants receive corticosteroids for a relapse, every effort will be made to obtain the 
scan prior to the first steroid dose if the presteroid scan is within 1 week of the scheduled 
visit. In all instances, the treatment of the relapse per the Investigator’s clinical judgment 
takes priority over the timing of the MRI scan. 
2. Oral tapering of corticosteroid rescue medication is permitted, with a maximum of 15 days 
of tapering allowed. 
3. In the treatment of acute exacerbations of MS, daily intramuscular or subcutaneous doses 
of Acthar gel (or equivalent, where approved), 80-120 units and not exceeding 3 weeks 
may be administered. An additional taper of up to 2 weeks with less frequent dosing 
frequency will be permitted as indicated.  
6.5.2 
Permitted Medicines  
The only permitted medications are the following: 
• Medications required per the medical history that: 
o Are not specifically prohibited by the protocol during the study,  
o Are considered necessary for the participants’ welfare, and  
o Will not interfere with the study intervention  
Medications under the conditions described above may be given at the Investigator’s discretion. 
There are no restrictions on the use of marijuana, where and as permitted by local regulations. 
Any medicines that are considered necessary to protect the participant’s welfare in emergencies 
may be given at the Investigator’s discretion, regardless if it results in a protocol deviation. 
However, as this may impact continued participation in the study, the Medical Monitor must be 
informed that prohibited medication was used. 
6.5.3 
Prohibited Medicines  
Medications prohibited before the study are listed in the exclusion criteria (see Section 5.2). 
The following medications and therapies are not permitted during the study and would require 
discontinuation of the study intervention:

• Rituximab, ofatumumab, ocrelizumab, and any other B cell depleting therapy, BTK 
inhibitors (excluding evobrutinib), mitoxantrone, or lymphocyte-depleting therapies (e.g., 
alemtuzumab, anti-CD4, cladribine, cyclophosphamide, azathioprine, total body 
irradiation, bone marrow transplantation).  
• Lymphocyte trafficking blockers (e.g., natalizumab, fingolimod, or siponimod).  
• Intravenous Ig therapy and/or plasmapheresis and immunosuppressive treatments (e.g., 
azathioprine, methotrexate).  
• Beta-interferons or glatiramer acetate.  
• Dimethyl fumarate, diroximel fumarate, other approved fumaric acid esters, or 
leflunomide. 
• Dantrolene. Other antispasticity agents are permitted at study entry if the participant has 
been on a stable dose over the 3 months prior to randomization. During the study, 
antispasticity agents can be added and/or the regimen modified based on the Investigator’s 
clinical judgment in order to manage the participant’s symptoms (see Section 6.5). 
• Medications known to lower the seizure threshold should be avoided. If treatment with 
these medications is required, the Investigator must inform the Medical Monitor. 
• Dalfampridine (Ampyra) or fampridine are not permitted during the DBTP and the 
DBE unless the participant has been on a stable dose for 3 months prior to 
randomization due to the possibility of confounding effects on key study measures. 
During the OLE period of the study, initiation of therapy with dalfampridine 
(Ampyra) is allowed if (1) indicated by the Treating Investigator, (2) no 
contraindication as per local label is present and (3) participant has been exposed 
to evobrutinib for at least 3 months. 
• Anticoagulation (e.g., warfarin), fish oil supplements, or antiplatelet therapy other than 
daily aspirin for cardioprotection. 
• CYP2C8 substrates with a narrow therapeutic index must also be stopped at least 1 day 
prior to randomization in the DBTP and should not be administered throughout the DBTP 
as well as the DBE. Only during OLE period of the study, CYP2C8 substrates with a 
narrow therapeutic index are not prohibited if indicated by the treating Investigator (see 
Appendix 11). 
• Medications known to be potent (strong to moderate) inhibitors of CYP3A, potent inducers 
of CYP3A, or drugs mainly metabolized by CYP3A with a narrow therapeutic index. 
Medications known to be CYP2B6 substrates with a narrow therapeutic index, as well as 
substrates of P-gp, BCRP, OCT1, MATE1 and/or MATE2K, while not prohibited, should 
be administered with caution. 
• Cholestyramine and activated charcoal, for use other than for AEP after discontinuation 
(see Appendix 8).  
• Live or live-attenuated vaccines. 
• Biologic therapies for MS are prohibited. Biologic therapies for other indications must be 
discussed with the Medical Monitor as their use may impact continued participation in the

study, with the exception of insulin and antibodies used for bone density (e.g., denosumab), 
which are permitted. 
• Systemic corticosteroids (oral, injected, IV) except as described in Section 6.5.1. Topical, 
intranasal, or inhaled corticosteroids are permitted. 
For further information on teriflunomide-related DDI, see Appendix 9 and refer to the locally 
approved product information (e.g., relevant SmPC or USPI). 
6.5.4 
Other Interventions  
Herbal or nutritional supplements (including, but not limited to, St. John’s wort, grapefruit, Seville 
oranges, cranberries, or juices of these fruits) known to be potent inhibitors of CYP3A must be 
stopped at least 1 week prior to randomization. As resveratrol supplements can significantly inhibit 
CYP3A, intake of resveratrol supplements must be limited to no more than 500 mg/day. 
Teriflunomide has additional potential for drug interactions and due to the blinded treatment 
assignment, these should be considered when treating participants. See Appendix 9 for potential 
teriflunomide DDI, as defined in the locally approved product information (e.g., relevant SmPC 
or USPI). 
6.6 
Dose Selection and Modification  
Not applicable. 
6.7 
Study Intervention after the End of the Study  
The Sponsor will not provide any additional care to participants after they leave the study because 
such care would not differ from what is normally expected for participants with relapsing forms 
of MS. 
6.8 
Special Precautions  
See Section 7.1 for precautions related to abnormal liver function. 
If any of the MRIs of the brain have findings suggestive of PML, CSF JCV PCR should be 
performed to rule out PML, see Appendix 7 for further details. See Section 7.1 for precautions 
related to suspected PML. 
6.9 
Management of Adverse Events of Interest  
Adverse events of special interests are liver AEs (possible drug-induced, non-infectious, 
non-alcoholic, and immune-mediated), infections (serious and opportunistic infections), lipase and 
amylase elevation, and seizure. All serious and nonserious AESIs must be additionally 
documented and reported as specified in Appendix 4.

Liver adverse events 
The elevations of transaminases observed in participants treated with evobrutinib were frequent, 
asymptomatic, and reversible on discontinuation of evobrutinib. The mechanism is unknown.  
Evobrutinib liver AESIs will include transaminases (> 3 × ULN), bilirubin elevations 
(> 1.5 × ULN), biological Hy’s Law cases based on laboratory data, any type of acute or chronic 
hepatitis (any grade), suspected drug-induced liver injury, acute or chronic hepatic failure, fibrosis, 
cirrhosis, and other liver damage-related conditions.  
Infections 
As per its mechanism of action, evobrutinib may impair B cell function which might lead to a 
decreased humoral immunity and consequently an increased risk of infection. Overall, in 
completed studies in participants the MedDRA SOC Infection was one of the most reported SOCs 
(e.g., in the MS200527_0086 RMS study approximately 18% to 32% of participants treated with 
evobrutinib reported infection; a similar rate was reported in the placebo group in the 0 to 24 week 
period), the individual events were of low grade, mainly Grade 1, nonserious and did not lead to 
study intervention discontinuation. Treatment of infections must be prompt and done in accordance 
with local standard of care depending on considerations such as the nature and severity of the 
infection and participant’s overall health status. Any CTCAE Grade ≥ 3 or SAEs of infection and 
opportunistic infection are considered as an AESI. 
Amylase and lipase elevations 
Asymptomatic elevations in amylase or lipase or both in participants treated with evobrutinib have 
been observed at a variety of time points and reported as TEAEs or noted as laboratory 
abnormalities. In RMS Study MS200527_0086, the incidence of TEAEs of lipase increased was 
slightly higher in evobrutinib 75 mg once daily and 75 mg twice daily arms (5 [9.4%] and 5 [9.3%], 
respectively) when compared to other arms (approximately between 4% to 6%). However, shifts 
from Baseline to highest grade on treatment were similar across all treatment arms for both 
amylase and lipase. In evobrutinib studies in other indications and in healthy participants the 
incidence of TEAEs of increased amylase or lipase, or both was infrequent and no clinically 
meaningful differences were observed across treatment arms. Any elevation of > 2 × ULN of 
lipase or amylase and any type of pancreatitis are classified as AESIs.  
Seizures 
Seizures are more common in patients with MS than in the general population, occurring in 2% to 
3% of MS patients (Poser 2003). Convulsions were observed in early studies of evobrutinib in 
dogs, however the plasma concentration of evobrutinib was approximately 140-fold greater than 
it is predicted for the dose used in this study. One participant with RMS with significant brain 
lesion load reported seizure of unclear clinical picture. The PK data for this participant did not 
exceed the expected values and was similar to other participants in the study. Anticonvulsant 
therapy was started and the participant continued treatment with evobrutinib with no reoccurrence. 
The Investigator did not consider the event to be related to evobrutinib. No event of 
convulsion/seizure was reported in other indications. Evobrutinib has been administered to 
approximately 800 patients with MS, RA and SLE. Moreover, an electroencephalogram study in

healthy volunteers did not show an epileptogenic potential for evobrutinib. Any type of 
seizures/epilepsy of any grade or its consequences are classified as AESIs.

Discontinuation of Study Intervention and Participant 
Discontinuation/Withdrawal  
7.1 
Discontinuation of Study Intervention  
In rare instances, it may be necessary for a participant to permanently discontinue (definitive 
discontinuation) study intervention. If study intervention is definitively discontinued, the 
participant will remain in the study to be evaluated for the SFU visit. The SoA indicates data to be 
collected at the time of discontinuation of study intervention and follow-up and for any further 
evaluations that need to be completed. 
The Investigator should discontinue study intervention when a participant meets one of the 
conditions outlined below or if the Investigator believes that it is in the best interest of the 
participant. Due to the prolonged half-life of teriflunomide, and the possibility that the participant 
received teriflunomide, accelerated elimination with cholestyramine, activated charcoal, or as per 
local standard of care may be considered (for more details see Appendix 8). In cases for which 
permanent discontinuation of study intervention is required, no rechallenge will be allowed. 
Liver function test-related monitoring and discontinuation criteria should be based on both central 
and local laboratory assessments depending on availability (i.e. participants should be discontinued 
if central or local laboratory result fulfills related criterion). The final decision should be based on 
the highest reported values (regardless of central or the local lab evaluation). 
Criteria for Permanent Discontinuation of Study Intervention: 
The Investigator should permanently discontinue study intervention upon confirmation of the 
criteria outlined below. 
For laboratory or assessment related criteria: 
• a neutrophil count < 500 / mm3 
• a neutrophil count 500–999 / mm3 with fever 
• platelet count < 25,000 / mm3 
• platelet count 25,000–49,999 / mm3 with bleeding 
• an increase in lipase to > 5 × ULN 
• an increase in amylase to > 5 × ULN 
• an increase in serum creatinine to > 3 × ULN 
• any other laboratory abnormality of clinical significance, with the exception of 
lymphopenia (see below) 
• QTcF > 500 msec OR an increase in QTcF > 60 msec relative to the participant’s 
Baseline ECG (Day 1) is observed and confirmed (with a second ECG).

• Detectable HBV DNA ≥ 20 IU/mL. Should this occur, consultations with specialists, 
such as a hepatologist, can be performed at the discretion of the Investigator and the 
Medical Monitor should be informed. In addition, a comprehensive hepatic/autoimmune 
panel is required (see below). 
 
Note: HBV DNA is assessed only in Hepatitis B antibody-positive participants 
during the study (see SoA [Section 1.3] and Exclusion Criterion 34). 
• Confirmed increase of ALT/AST ≥ 5 ULN (without increased bilirubin values). 
• Confirmed increase of total bilirubin > 2 ULN (without increased ALT/AST values). 
For an increase in AST and/or ALT to > 3 × ULN in combination with an increase in bilirubin to 
> 2 × ULN, the study intervention should be permanently discontinued and the Medical Monitor 
informed. In addition, a comprehensive hepatic/autoimmune panel is required (see below). 
For other reasons: 
• Pregnancy. As a pregnant participant may have received teriflunomide and due to the 
prolonged half-life of teriflunomide, an AEP should be performed and a teriflunomide 
level < 0.02 mg/L should be reached (for more details see Appendix 8). 
• Any events that endanger the safety of the participant. 
• Sponsor decision to end clinical study. 
• Adverse events, if discontinuation of study intervention is desired or considered 
necessary by the Investigator and/or participant. 
• Noncompliance regarding study intervention (see Section 6.4). 
• Extended interruption of the study treatment for more than 30 days for any reason, 
except during AEP (between DBE period and OLE period) where a treatment gap over 
30 days is acceptable if approved by the Medical Monitor. 
• Use of prohibited medications, as defined in Section 6.5.3.  
o Note: Any medications that are considered necessary for the participant’s well-being 
may be given at the discretion of the Investigator. However, as this may impact 
continued participation in the study, the Medical Monitor must be informed that 
prohibited medication was used, and a protocol deviation should be documented.  
• Lack of efficacy and/or progression of MS as defined by Investigator judgment or when 
a medication other than permitted medications (as defined in Section 6.5.2) is needed 
for treatment (see above regarding prohibited medications). 
Criteria for Temporary Discontinuation of Study Intervention: 
The Investigator should temporarily discontinue study intervention for the discontinuation criteria 
outlined below, inform the Medical Monitor, and perform confirmatory testing as instructed. 
Depending on the result of the confirmatory test (i.e., performed centrally or locally), the 
Investigator should follow instructions as outlined below, including permanently discontinuing 
study intervention, when indicated.

For any study intervention discontinuation related to laboratory or assessment results, the 
participant should be followed with additional testing as needed until a return to within normal 
limits or an acceptable value. In cases for which permanent discontinuation of study intervention 
is required, no rechallenge will be allowed. 
Liver Function Testing criteria: 
• For an increase in AST or ALT to > 3 × to < 5 × ULN, temporarily interrupt the study 
intervention and recheck the value within 72 hours to confirm the reported elevation. 
• If AST and/or ALT > 3 × ULN to < 5 × ULN are confirmed within 72 hours and have 
increased by more than 50% (compared to latest confirmed value), continue interruption 
of the study intervention with an additional recheck in 72 hours later. 
o If rechecked value in the second recheck has decreased to < ULN or < participant’s 
baseline, rechallenge can be considered in the absence of hyperbilirubinemia. 
o In all other cases, permanently discontinue the study intervention and inform the 
Medical Monitor. 
• If AST and/or ALT > 3 × ULN to < 5 × ULN are confirmed within 72 hours and have 
increased by less than 50% (compared to latest confirmed value), continue interruption 
of the study intervention with an additional recheck in 1 week. 
o If rechecked value in the second recheck has decreased to < ULN or < participant’s 
baseline, rechallenge can be considered in the absence of hyperbilirubinemia. 
o In all other cases, permanently discontinue the study intervention and inform the 
Medical Monitor. 
• For an increase in bilirubin of > 1.5 × to ≤ 2 × ULN, temporarily interrupt the study 
intervention and recheck the value within 72 hours to confirm the reported elevation. 
o If the value is still > 1.5 × to ≤ 2 × ULN upon recheck, continue temporary 
interruption of the study intervention with an additional recheck in 1 week. 
o If the value is still > 1.5 × to ≤ 2 × ULN upon second recheck, the study intervention 
should be permanently discontinued and the Medical Monitor informed. 
o If the value has decreased to ≤ 1.5 × ULN, the Investigator may reinitiate study 
intervention (see Section 7.1). 
Any re-challenge associated with LFT elevations should follow the weekly monitoring for 
12 weeks. 
For participants who temporarily or permanently discontinue study intervention because of 
abnormal liver function or detection of HBV DNA (see Exclusion Criterion 34), consultations with 
specialists, such as a hepatologist and liver imaging such as ultrasound are encouraged to exclude 
potential alternative causes of liver injury. In addition, a comprehensive hepatic/autoimmune panel 
is required, including the following (performed by central laboratory, unless otherwise stated): 
• International normalized ratio (INR), partial thromboplastin time, fibrinogen, high sensitivity 
C reactive protein

• For any other laboratory increase/decrease (as relevant) from Baseline to a clinically significant 
higher severity grade, temporarily discontinue study intervention and recheck the value within 
72 hours of receipt (and no later than 1 week). The Investigator may reinitiate study intervention 
if an improving trend is observed. 
For other reasons: 
• At the first sign or symptom suggestive of PML, or brain MRI suggestive of PML, temporarily 
discontinue the study intervention and check for CSF JCV PCR (performed by central 
laboratory). If positive, permanently withdraw the study intervention (see Appendix 7). 
The SoA specifies the data to collect at study intervention discontinuation and follow-up, and 
any additional evaluations that need to be completed. 
7.1.1 
Temporary Discontinuation  
See Section 7.1 for specific criteria for temporary discontinuation related to abnormal laboratory 
values. 
7.1.2 
Rechallenge  
See Section 7.1 for specific criteria for rechallenge following temporary discontinuation for 
abnormal laboratory values.  
7.2 
Participant Discontinuation/Withdrawal from the Study  
• A participant may withdraw from the study at any time, at his/her own request or may be 
withdrawn at any time at the discretion of the Investigator for safety, behavioral, compliance, 
or administrative reasons. 
• If a participant is permanently withdrawn from study intervention due to stopping rules (see 
Section 7.1), the participant should also be withdrawn from the study. 
• At the time it is determined that a participant is withdrawing from the study, the participant 
should, if possible, return for an Early Discontinuation Visit, as listed in the SoA. The SoA 
specifies the data to collect at study discontinuation and follow-up, and any additional 
evaluations that need to be completed. 
• Subsequent to the Early Discontinuation Visit, the participant should, if possible, enter the 
4-week Safety Follow-Up Period. At the end of that 4-week period, the participant should 
return for the 4-week Safety Follow-up Visit. After completing this visit, the participant 
would be discontinued from the study. 
• If the participant withdraws consent for future involvement in the study, any data collected 
up to that point may still be used, but no future data can be generated, and any biological 
samples collected will be destroyed. 
• A participant has the right at any time to request destruction of any biological samples taken. 
The Investigator must document this in the site study records.

Participants who have discontinued after randomization (e.g., due to AEs or lack of efficacy; see 
Section 7.1) will not be replaced. Participants who discontinue from the study should return for 
the Early Discontinuation Visit and the Safety Follow-up Visit 4 weeks from the day of 
discontinuation of study interventions.  
7.3 
Lost to Follow-Up  
A participant will be considered lost to follow-up if he or she repeatedly fails to return for 
scheduled visits and is unable to be contacted by the study site. 
The following actions must be taken if a participant fails to return to the clinic for a required study 
visit: 
• The site must attempt to contact the participant and reschedule the missed visit as soon as 
possible, counsel the participant on the importance of maintaining the assigned visit schedule, 
and ascertain if the participant wants to or should continue in the study. 
• Before a participant is deemed “lost to follow-up”, the Investigator or designee must make every 
effort to regain contact with the participant: 1) where possible, make 3 telephone calls, 2) if 
necessary, send a certified letter (or an equivalent local method) to the participant’s last known 
mailing address, and 3) if a participant has given the appropriate consent, contact the 
participant’s general practitioner for information. These contact attempts should be documented 
in the participant’s medical record. 
• Should the participant continue to be unreachable, he/she will be considered to have withdrawn 
from the study. 
8 
Study Assessments and Procedures  
• Study assessments and procedures and their timing are summarized in the SoA. 
• No protocol waivers or exemptions are allowed. 
• Immediate safety concerns should be discussed with the Sponsor immediately upon occurrence 
or awareness to determine if the participant should continue or discontinue study intervention. 
• Adherence to the study design requirements, including those specified in the SoA, is essential 
and required for study conduct. 
• All screening evaluations must be completed and reviewed to confirm that potential participants 
meet all eligibility criteria. The Investigator will maintain a screening log to record details of 
all participants screened, to confirm eligibility, and if applicable, record reasons for screening 
failure. 
• Prior to performing any study assessments that are not part of the participant’s routine medical 
care, the Investigator will obtain written informed consent as specified in Appendix 2 Study 
Governance. 
• Procedures conducted as part of the participant’s routine medical care (e.g., blood count) and 
obtained before signing of the ICF may be used for screening or Baseline purposes provided 
the procedures met the protocol-specified criteria and were performed within the time frame 
defined in the SoA, if reviewed and approved by the Sponsor.

The following data will be collected:  
• Demography: date of birth, sex (gender), ethnicity, and race, as permitted by local regulations. 
• Medical history (including diagnosis and duration of MS): previous illness and surgeries (e.g., 
all during the past year and only major ones prior to that), concomitant illness, allergies, prior 
therapies for the target indication and reason for switch (i.e., relevant previous medications), 
therapies stopped or changed at entry into the study (includes use of drugs, alcohol, tobacco, 
and caffeine), special diets and, for women, menstrual status. 
• Participants will be asked to record the following information daily in a paper participant diary:  
• dosing date and time 
• food intake around time of dosing (only on the day prior to PK sampling and the day of PK 
sampling, and around the time of the last dose prior to evobrutinib concentration assessment 
sampling). 
All blood and urine tests will be analyzed by a central laboratory, with the following exceptions: 
• Urine testing for β-human chorionic gonadotropin will be conducted at the local laboratories. 
• Urine dipstick results will be interpreted locally. Urine microscopic examination will be 
conducted centrally. Please see the SoA (see Section 1.3) and Appendix 5 for information 
regarding abnormal dipstick results.  
• PK, PD, and biomarker samples will be analyzed by the analytical laboratories specified by the 
Sponsor. 
• HIV testing should be conducted centrally. Where required by local regulations, can be 
conducted, and analyzed locally. 
• T-SPOT test will be conducted at the local laboratories after an indeterminate or positive 
QuantiFERON test. 
• A standard 12-lead ECG will be performed (see Section 8.2.3).  
Screening 
See the SoA (see Section 1.3) for a list of assessments completed at Screening. 
The Screening packet will be reviewed by the Medical Monitor. See Appendix 2 for further details. 
The Screening Period may be extended after approval by the Medical Monitor (but cannot exceed 
12 weeks) when a laboratory test must be repeated or reflex testing must be performed, an 
unanticipated event occurs, or for participants who have used systemic corticosteroids for their MS 
before Screening. For a participant to be eligible, systemic corticosteroids should not have been 
administered between Screening and Baseline. See Appendix 2 for details of the steps to be 
performed.

Accelerated Elimination Procedure (At Screening Visit for OLE only) 
All participants previously treated with teriflunomide, or unknown exposure status during the 
DBTP and DBE period, entering the OLE must undergo an AEP for teriflunomide. The AEP is to 
be initiated at the Screening visit upon signing of ICF and initial screening and completed during 
11 consecutive days preferably within a 30-day period before Day 1 of the OLE (refer to Appendix 
8). If justified for clinical or logistical reasons, an extension of the 30-day period for the AEP 
procedure is possible upon approval by the Medical Monitor. The Investigator should dispense 
cholestyramine or activated charcoal and to instruct participant about proper intake. The blood 
concentration of teriflunomide has to be verified upon completion of the AEP via blood sample 
collection between Day 12 to Day 30 at the central laboratory. The Investigator will remain blinded 
to the teriflunomide levels. Please refer to the study-specific central laboratory manual for detailed 
information on the sampling procedures. The Investigator is responsible to ensure proper and 
timely completion of the AEP and will document completion at the Day 1 visit prior to the IWRS 
call and dispensation of the IMP. 
Retesting before Baseline 
In case the Screening laboratory samples are rejected by the central laboratory or the results are 
not assessable or abnormal, the tests need to be repeated once within 4 weeks. Any abnormal 
Screening laboratory value that is clinically relevant should be retested once in order to rule out 
any progressive or uncontrolled underlying condition. The last value before randomization must 
meet study criteria. In such circumstances, the Screening Period may need to be prolonged after 
approval by the Medical Monitor but should not exceed 12 weeks. 
In the event that an initial ferritin and/or transferrin saturation is abnormal and needs to be repeated, 
consider having participants abstain from iron supplements and vitamin C for 1 week prior to 
retest, and perform the retest as a fasting collection. 
For screen failures, see Section 5.6. 
Rescreening 
Participants who are considered screen failures after a first Screening Period may undergo 
rescreening once, after approval by the Medical Monitor. For those participants, the Screening 
Period for rescreening may be extended after approval by the Medical Monitor (but cannot exceed 
12 weeks) for the reasons described above. If a participant is rescreened, all Screening tests will 
need to be repeated except as follows: 
a. Documented TB testing if occurred within 3 months prior to the rescreening visit. 
b. Hepatitis and HIV testing if occurred within 1 month prior to the rescreening visit. 
Unscheduled Visit 
Participants should be instructed that if, at any point during the study, they suspect that they are 
experiencing new or worsening neurological symptoms, including possible relapse, they should 
contact the Investigator as soon as possible after the onset of symptoms. If necessary, the 
participant should be evaluated by the Treating Investigator and if appropriate, the Examining

Investigator (assessor), within the clinic and every effort should be made to complete this 
evaluation within 1 week after the start of symptoms. Any assessments needed to confirm the 
relapse (EDSS) should be performed during the same visit. Details should be documented within 
the relevant section(s) of the eCRF. The definition of a qualifying and nonqualifying relapse is 
provided in Section 8.1.1.1. Once the assessments by the Treating Investigator and the Examining 
Investigator (assessor) are completed, the reported relapse will be adjudicated by the EAC. During 
OLE, the full assessments of relapse should be completed by Treating Investigator also at the same 
visit (neurological exams and EDSS). 
If an MRI scan is indicated at an Unscheduled Visit for Neurological Worsening and Relapse 
Assessment, it should be performed prior to initiating corticosteroid therapy, where possible. In 
addition, care should be taken to avoid the participant being exposed to gadolinium more than once 
in a 4-week period, i.e., it may be necessary to cancel the MRI scan at the next scheduled visit (all 
other assessments should be completed at the visit as normal). If the Unscheduled Visit is 
conducted for a safety concern the assessments described below should be completed and any 
additional assessments and further management will be at the discretion of the Investigator. 
The following will be performed at an Unscheduled Visit: 
• Review of concomitant medications and procedures, evaluation of AEs, disease activity 
assessment (relapse assessment, EDSS), complete physical examination, vital signs, and a 
neurologic exam. 
• Blood sample collection for safety assessments (hematology and biochemistry). 
• Urine collection for urinalysis, and, if necessary, microscopy. 
• Additional assessments can be performed at the discretion of the Investigator. 
Telephone Contact 
If a clinic visit is not scheduled, Telephone contacts will be scheduled with participants as indicated 
in the SoA (Section 1.3). During the Telephone contacts, the following should be discussed with 
the participant:  
• Structured Interview (see Appendix 10) 
• Pregnancy, if applicable, including confirm completion of home pregnancy testing and discuss 
results 
Telephone contacts between D1 and W44 are not expected to occur every 4 weeks, since 
participants are scheduled to be on site at least every 4 weeks. However, if a participant is utilizing 
the home visit option, telephone contacts should occur as indicated in the SoA. 
Telephone contacts between W44 and W156 should occur every 4 weeks if a clinic visit is not 
scheduled. 
Participants experiencing new or worsening neurological symptoms, including possible relapse, 
should be evaluated by the Investigator, if necessary, at an Unscheduled Visit.

Double-blind Extension Period 
After completing the DBTP (flexible duration up to 156 weeks) or at the time of PA trigger, all 
participants will be considered treatment completers and offered the opportunity to continue 
treatment assigned at randomization in the DBE. Signed consent will also be obtained prior to 
participation in the DBE period.  
Scheduled assessments will be performed according to the SoA (see Section 1.3.2) before 
administration of study intervention. All scheduled visits during the DBE period may take place 
within the visit windows specified in the SoA. Participants who discontinue early must return for 
the End-of-DBE Visit (Week 96/ED/EODBE). For further details see Sections 1.3.2 and 4. 
Open Label Extension Period 
After completing the DBE period (up to 96 weeks) and if the long-term follow-up study is not yet 
open for enrollment, participants will be considered treatment completers and offered the 
opportunity to continue the treatment with evobrutinib in an OLE period under the current 
protocol. Signed consent will also be obtained prior to participation in the OLE period. 
Scheduled assessments will be performed according to the SoA (see Section 1.3.3) before 
administration of the study intervention. All scheduled visits during the OLE period may take place 
within the visit windows specified in the SoA. Participants who discontinue early must return for 
the OLE End of Treatment Visit (Week 96/ED/EOT). For further details see Sections 1.3.3 and 4. 
8.1 
Efficacy Assessments and Procedures  
8.1.1 
Neurological Assessment  
The Examining Investigator should ideally be a neurologist. However, if a neurologist is not 
available to perform the scope of the Examining Investigator’s tasks, other raters can be considered 
for the study as delegates; the delegate assigned for EDSS must be approved on a case-by-case 
basis by the Sponsor. 
The Examining Investigator (assessor) or Qualified Examining Designee will perform the 
neurological examination, document the FSS, and assess EDSS scores. The Examining 
Investigator (assessor) or Qualified Examining Designee will be also responsible for performing 
and documenting results from: T25-FW, 9-HPT and the SDMT. He or she will have access only 
to data from assessments listed above. The Examining Investigator (assessor) or Qualified 
Examining Designee will not be involved with any aspect of medical management of the 
participant and will not have access to participant data. Every effort will be made to ensure that 
there is no change in the Examining Investigator (assessor) or Qualified Examining Designee 
throughout the course of the study for any individual participant. The Examining Investigator 
(assessor) or Qualified Examining Designee will be trained and instructed not to discuss what 
adverse effects (if any) the participant is experiencing from their medication. The Examining 
Investigator (assessor) or Qualified Examining Designee will receive training in performing EDSS 
assessments prior to the beginning of the study and must have successfully passed an examination 
on performance of the Neurostatus EDSS examination, achieving Level C qualification, within 24

months of participation. All Examining Investigators (assessors) and Qualified Examining 
Designees will maintain ongoing training on performance of the Neurostatus EDSS examination 
and must maintain Level C qualification throughout the course of the study. 
Prior to being examined by the Examining Investigator (assessor), Treating Investigator and/or 
study coordinators should remind participants not to discuss what (if any) adverse effects they may 
be experiencing; this should be documented in the source documents. 
During the OLE period, the Investigator or Qualified Examining designee will perform 
neurological examination and assess EDSS scores. The Investigator or Qualified Examining 
designee will be also responsible for performing and documenting results from: Timed 25-foot 
Walk (T25-FW), 9-Hole Peg Test (9-HPT) and the Symbol Digit Modalities Test (SDMT). The 
assessor should ideally be a neurologist. However, if a neurologist is not available to perform the 
task, other site personnel can be considered for the study as Qualified Examining designee. 
The Investigator or Qualified Examining Designee must have successfully passed an examination 
on performance of the Neurostatus EDSS examination, achieving Level C qualification, within 
24 months of participation. All assessors and Qualified Examining Designees will maintain 
ongoing training on performance of the Neurostatus EDSS examination and must maintain Level 
C qualification throughout the course of the study. 
8.1.1.1 
Qualified Relapse  
A qualifying relapse is the occurrence of new or worsening neurological symptoms attributable to 
MS (for > 24 hours, no fever, infection, injury, AEs, and preceded by a stable or improving 
neurological state for ≥ 30 days). The relapse should be accompanied by an increase of ≥ 0.5 
EDSS, or 2 points increase on 1 of the FSS, or 1-point increase on ≥ 2 of the FSS. The increase in 
FSS scores must be related to the neurological symptoms which were reported as new or 
worsening. The change must affect the selected FSS (i.e., pyramidal, cerebellar, brainstem, 
sensory, or visual, excluding cerebral, bladder or bowel). 
Episodic spasms, sexual dysfunction, fatigue, and mood change will not suffice to establish a 
relapse. 
Adjudication of qualified relapses during the DBTP and DBE period (regardless of whether they 
are identified during a scheduled or unscheduled visit) will be performed by the EAC based on 
prespecified criteria, applied to data collected by the Treating and Examining Investigator, in a 
blinded fashion. During the OLE period, relapses will be evaluated, reported, and qualified by the 
Investigator only and no further adjudication via EAC will be performed. Any assessments needed 
to confirm the relapse should be performed, and details of the relapse should be documented within 
the relevant section(s) of the eCRF. The criteria for a qualified relapse should be clear and there 
should be documentation of how each potential relapse did or did not meet the criteria. Participants 
who have a documented relapse during treatment are not required to discontinue study intervention 
unless they meet any of the criteria for discontinuation from the study intervention (see Section 7). 
Relapse assessments may be conducted as phone assessments between study site visits. If 
neurological signs and symptoms are identified that are consistent with relapse, the participant 
should be evaluated on site.

The annualized relapse rates up to 156 weeks will be calculated based on qualified relapses. 
8.1.1.2 
Disability Progression and Expanded Disability Status Scale  
Disability progression is defined as an increase of ≥ 1.0 point from the Baseline EDSS score that 
is not attributable to another etiology (e.g., fever, concurrent illness, or concomitant medication) 
when the Baseline score is 5.0 or less and an increase of ≥ 0.5 when the Baseline score is 5.5. 
Disability progression is considered sustained when the initial increase in the EDSS is confirmed 
at a regularly scheduled visit at least 12 weeks or 24 weeks, after the initial documentation of 
neurological worsening. 
CDP, sustained for 12 and 24 weeks after the initial documentation of neurological worsening, 
will be analyzed as secondary endpoints. 
8.1.1.3 
Confirmed Disability Improvement  
Disability improvement will be analyzed only for the subgroup of participants with a Baseline 
EDSS score ≥ 2.0 to ensure relevant baseline disability that is potentially amenable to 
improvement. Disability improvement is defined as a reduction of 1 point from Baseline EDSS 
score when the Baseline score is ≥ 2 and ≤ 6 and a reduction of 0.5 point from Baseline EDSS 
score when the Baseline score is ≥ 6.5 and ≤ 9.5. Disability improvement is considered sustained 
when the initial reduction in the EDSS score is confirmed at a regularly scheduled visit at least 24 
weeks after the initial reduction. 
CDI, sustained for 24 weeks after the initial documentation of neurological improvement, will be 
analyzed as a secondary endpoint. 
8.1.1.4 
Timed Twenty-Five Foot Walk  
The T25-FW is a quantitative mobility and leg function performance test based on a timed 25-foot 
walk. The participant 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 time is calculated from the initiation of the 
instruction to start and ends when the participant has reached the 25-foot mark. The task is 
immediately administered again by having the participant walk back the same distance. 
Participants may use assistive devices when doing this task. T25-FW will be administered by the 
Examining Investigator (assessor) or Qualified Examining Designee in DBTP/DBE period and by 
qualified non-blinded site personnel during OLE period. 
A worsening of ≥ 20% is considered to have occurred in this task, when the time it takes to 
complete the task is longer by equal to or more than 20% than the time it took at Baseline. The 
worsening is considered confirmed at 12 weeks if the following assessment (at a scheduled visit 
of 12 weeks or more after the initial observed worsening) confirms it. 
8.1.1.5 
Nine Hole Peg Test  
The 9-HPT is a brief, standardized, quantitative test of upper extremity function. Both the 
dominant and nondominant hands are tested twice. The participant is seated at a table with a small,

shallow container holding nine pegs and a wood or plastic block containing nine empty holes. On 
a start command when a stopwatch is started, the participant picks up the nine pegs one at a time 
as quickly as possible, puts them in the nine holes, and, once they are in the holes, removes them 
again as quickly as possible one at a time, replacing them into the shallow container. The total time 
to complete the task is recorded. Two consecutive studies with the dominant hand are immediately 
followed by two consecutive studies with the nondominant hand. 9-HPT will be administered by 
the Examining Investigator (assessor) or Qualified Examining Designee in DBTP/DBE period and 
by qualified non-blinded site personnel during OLE period. 
A worsening of > 20% (either hand) is considered to have occurred in this task, when the time it 
takes to complete the task is longer by equal to or more than 20% than the time it took at Baseline. 
The worsening is considered confirmed at 12 weeks if the following assessment (at a scheduled 
visit of 12 weeks or more after the initial observed worsening) confirms it. 
8.1.1.6 
Symbol Digit Modalities Test  
The SDMT has demonstrated sensitivity in detecting not only the presence of cognitive 
impairment, but also changes in cognitive functioning over time and in response to treatment. The 
SDMT is brief, easy to administer, and involves a simple substitution task that normal children 
and adults can easily perform. Using a reference key, the examinee has 90 seconds to pair specific 
numbers with given geometric figures. Responses will be written and administration time is just 5 
minutes. SDMT will be administered by the Examining Investigator (assessor) or Qualified 
Examining Designee in DBTP/DBE period and by qualified non-blinded site personnel during 
OLE period. 
Two different SDMT forms will be used, administered at alternating visits, to overcome learning 
effects. 
8.1.2 
Brain Magnetic Resonance Imaging Scans  
If a participant discontinues the study more than 4 weeks after his or her most recent MRI, during 
the double-blind, double-dummy phase of the Treatment Period, an MRI may be obtained at the 
Discontinuation Visit. The Screening MRI scan should be acquired before randomization and 
dosing to allow baseline evaluation by the central MRI reader (before randomization). 
Magnetic resonance imaging is a useful tool for monitoring CNS lesions in MS. Various MRI 
derived parameters have been related to disease activity, including T1 weighted 
gadolinium-enhancing (T1 Gd+) lesions and new or enlarging hyperintense T2 (active T2) lesions. 
Other MRI readouts such as chronic T1 hypo-intense lesions are reflective of long-term brain 
damage (black holes). Combined unique active lesions are defined as the sum of new T1 Gd+ 
lesions and active T2 lesions (without double counting). It is hypothesized that changes in brain 
volume may reflect brain atrophy as a result of MS-related tissue loss and may thereby correlate 
with long-term clinical outcome in these participants (De Stefano 2002). 
Brain MRI scans will be performed according to a standardized imaging protocol before and after 
the administration of single-dose gadolinium. Further details, including the scans required and the

optimal MRI workflow, will be provided in a separate Imaging Manual that will be provided to 
each study site.  
Images will be assessed by an independent, blinded, centralized MRI reading service, provided by 
NeuroRx Research. The assessment will be performed in the absence of clinical information. At 
the site level, the local radiologist assigned to this study will have access to the MRI scans and 
produces the local reports to inform the Treating Investigator of any noted safety issues. The 
Treating Investigator has access to the Screening (baseline) MRI scan in order to evaluate 
eligibility (see Section 5.1, inclusion criterion 3b) and, during the DBTP and DBE period of the 
study, to local MRI reports only in case of safety-related issues (e.g., non-MS pathologies) to 
preserve the blinding of the data. When assessment of the local MRI report is required for safety 
concerns, a blinded report will be provided to the Treating Investigator by the local radiologist 
containing only non-MS pathology information. In addition, the Treating Investigator may inquire 
about an overall increase in new lesions observed, but this information must not be shared 
proactively or in detail by the local radiologist (such as number, type, or location of MS lesions). 
This inquiry should only occur annually and not more frequently. Overall, the Treating Investigator 
should never have access to the detailed MRI report to preserve the integrity of the study data.  
Independent safety-reads of all MRI scans can be obtained from the local radiology centers. 
In addition, if a scheduled MRI scan is delayed or an unscheduled MRI scan is indicated, care 
should be taken to avoid the participant being exposed to gadolinium more than once in a 4-week 
period, i.e., it may be necessary to cancel the MRI scan at the next scheduled visit (all other 
assessments should be completed at the visit as per schedule). For example, if the next scheduled 
visit is the Week 96, the Week 96 MRI scan should be performed as soon as the 4-week period 
since previous exposure to gadolinium has elapsed. 
Gadolinium will be used to enhance T1-weighted lesions and to optimize clarity and accuracy of 
reporting. As gadolinium is excreted renally, participants with acute renal insufficiency (eGFR 
< 60 mL/min/1.73 m2) will be excluded from the study (see Section 5.2). 
In the OLE period, only those participants who have completed Week 96 and DBTP as well as 
DBE End-of-Treatment MRI assessments will be offered participation in a respective OLE MRI 
substudy. The End-of-DBE MRI will also serve as baseline MRI of the OLE and will require to 
preserve the blinding outlined for the DBTP and DBE period as described in the paragraphs above. 
During the OLE period, the Treating Investigator will have access to the full MRI reports including 
MS pathology (starting with the first MRI assessment in the OLE period at Week 48). Irrespective 
of the MRI substudy, all participants in the OLE period will have access to MRI evaluations for 
safety reasons if indicated by the Investigator. 
8.1.3 
Patient Reported Outcomes  
PRO data will be collected at the study visit with an electronic tablet device at specified study 
visits (see the SoA for details, Section 1.3). The tablet with the PRO instruments will be distributed 
by the Investigator staff and completed in their entirety by the participant. In the event of a tablet 
device not being available, an alternative method of data collection may be used.

PROs should be completed prior to administration of study intervention and prior to any other 
study assessment(s) to ensure the validity of the instruments is not compromised, and data quality 
meets requirements of the Guidance for Industry Patient-Reported Outcome Measures: Use in 
Medical Product Development to Support Labeling Claims (Food and Drug Administration 
[FDA] 2009). 
PRO data will be elicited from participants in this study to better characterize the clinical profile 
of evobrutinib. These PRO measurements are described in Section 8.1.3. Please note that the 
methods for collecting and analyzing PRO data are different from those for the ascertainment of 
observed or volunteered AEs. Due to these differences, PRO data will not be reported as AEs and 
no attempt will be made to resolve any noticeable severe symptoms or functional status. 
To ensure missing data are minimized, all participants will be given detailed information and 
training about the nature of the PRO assessments and importance of such information for the study, 
at or prior to study start (based on materials provided).  
Further guidance/information for study sites on procedures for collecting electronic PROs 
(ePROs), as well as strategies to ensure complete and high-quality PRO data will be provided in 
the study manual of operations. 
8.1.3.1 
Patient Reported Outcomes Measurement Information 
System  
The NIH PROMIS comprises an extensive set of item banks and short-form measures created from 
the item banks that assess physical, mental, and social aspects of health in adults and children, 
including symptoms such as pain, fatigue, and sleep disturbance, and health domains such as PF 
(Cella 2007). 
The PROMIS PF item bank was identified as having great potential for the evobrutinib program 
due to several factors, despite limited previous use in MS (Amtmann 2018), and lack of an MS-
specific short form. First, the content includes all key aspects of PF domain, such as IADL, lower 
extremity (mobility), back and neck (central), and upper extremity functioning domains 
(Rose 2014). Second, the development process of PROMIS items included a rigorous development 
and calibration process, ensuring the technical quality of items. Further, items capture the full 
continuum of PF, from low to high levels, which is a useful characteristic for capturing changes 
over time. A short form specific to MS was developed with input from MS patients (n = 57) and 
validated in 2 observational studies. Measures from the PF item bank are scored on a T-score 
metric (higher scores = higher PF). An MID estimate of 2.7 is proposed for worsening PF for the 
PROMISnq PF(MS)15a (Kamudoni 2022). 
The PROMIS Fatigue item bank includes 95 items assessing the experience (frequency, duration, 
and intensity) as well as the impacts of fatigue on physical, mental, and social activities (Lai 2011). 
Psychometric properties of this bank have been established across different clinic populations 
(Cella 2016). An 8-item short-form specific to MS, derived based on input from clinicians (n = 36) 
and participants with MS (n = 48), is available (Cook 2012). This short form was further validated. 
Measures from the fatigue item bank are scored on a T-score metric (higher scores= higher

fatigue); An MID estimate of 4 is proposed for minimal improvement and minimal worsening in 
the PROMIS Fatigue (MS) 8a scores (Kamudoni 2021). 
The PROMIS approach offers flexibility in the selection of items and how these are administered, 
including use of bespoke measures, fixed short forms, or computerized adaptive testing. PROMIS 
based short forms for physical functioning and fatigue are currently in preparation for FDA 
qualification as a DDT in MS (MS Working Group, 2018; DDT COA, 2018). 
Physical function deterioration is defined as a reduction in PROMIS PF T-score ≥ 2.7 compared 
to Baseline PROMIS PF T-score sustained for at least 12 weeks. 
8.1.3.2 
Medical Outcomes Study 36-Item Short Form Survey 
Instrument  
The Medical Outcomes SF-36v2 is a 36-item questionnaire that measures 8 areas of participant 
reported health rated from 0 to 100 (McHorney 1992, Ware 1992, McHorney 1993, 
McHorney 1994, and Freeman 2000). The areas are:  
• Physical function 
• Role limitations due to health problems 
• Bodily pain 
• Social functioning 
• General mental health 
• Role limitations due to emotional problems 
• Energy/fatigue 
• General health perceptions 
The instrument will be used to calculate a normalized score for each of the 8 health domain scales, 
a PCS score, and a MSC score, with higher scores indicating better health.  
8.1.3.3 
EuroQoL 5 Dimension 5 Levels  
The EQ-5D is a standardized instrument developed as a measure of health-related quality of life 
that can be used in a wide range of health conditions and treatments. The EQ-5D-5L was 
introduced in 2009 to improve the instrument’s sensitivity and to reduce ceiling effects, as 
compared to the EQ-5D-3L. The EQ-5D-5L essentially consists of 2 pages: the EQ-5D descriptive 
system and the EQ VAS. 
The descriptive system comprises five dimensions: mobility, self-care, usual activities, 
pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight 
problems, moderate problems, severe problems, and extreme problems. The levels of the five 
dimensions can be combined into a 5-digit number that describes the patient’s health state.

EQ-5D-5L health states, defined by the EQ-5D-5L descriptive system, may be converted into a 
single health utility index value using country specific value sets. Health utility values facilitate 
the calculation of quality-adjusted life years that are used to inform pharmacoeconomic 
evaluations of health care interventions.  
The EQ VAS records the respondent’s self-rated health on a 20 cm vertical, visual analogue scale 
with endpoints labeled ‘the best health you can imagine’ and ‘the worst health you can imagine’. 
This information can be used as a quantitative measure of health as judged by the individual 
respondents. 
Higher scores on both EQ-5D-5L health utility values and EQ VAS represent a better HRQoL. 
8.1.3.4 
WPAI: MS v2.0 (for OLE Period Only)  
Change in disability, fatigue, cognition, and health related quality of life are known to impact 
physical absence from work (i.e., absenteeism) and reduced productivity while working (i.e., 
presenteeism) and by that cause substantial costs. Work productivity and absenteeism is assessed 
to characterize the associations with disability, fatigue, cognition, and health-related quality of life. 
The Work Productivity and Activity Impairment Questionnaire: Multiple Sclerosis, Version 2.0 
(WPAI: MS v2.0) is a validated and reliable 6-item questionnaire developed to measure the effect 
of multiple sclerosis on the ability to work and perform regular activities during the last seven 
days. The instrument yields four types of scores: 
• Absenteeism (work time missed) 
• Presenteeism (impairment at work / reduced on-the-job effectiveness) 
• Work productivity loss (overall work impairment / absenteeism plus presenteeism) 
• Activity Impairment 
WPAI outcomes are expressed as impairment percentages, with higher numbers indicating greater 
impairment and less productivity, i.e., worse outcomes. 
WPAI:MS v2.0 will be assessed in a subset of participants based on questionnaire availability for 
individual countries and languages. 
8.2 
Safety Assessments and Procedures  
The safety profile of the study intervention will be assessed through the recording, reporting and 
analysis of Baseline medical conditions, AEs, physical examination findings, vital signs, ECGs, 
and laboratory tests including Ig and subclass concentration.  
Comprehensive assessment of any potential toxicity experienced by each participant will be 
conducted starting when the participants give informed consent and throughout the study. The 
Investigator will report any AEs, whether observed by the Investigator or reported by the 
participant; the reporting period is specified in Section 8.3.1.

8.2.1 
Physical Examinations  
• A complete physical examination will include, at a minimum, assessments of the 
Cardiovascular, Respiratory, Gastrointestinal and Neurological systems. 
• Investigators should pay special attention to clinical signs related to previous serious illnesses. 
Any physical exam abnormality findings, which are identified as clinically significant before the 
ICF is signed, will be captured on the Medical History eCRF. After the ICF is signed, any new 
physical exam abnormality findings will be captured on the Adverse Event form. 
8.2.2 
Vital Signs  
• Height at Screening and weight will be measured and recorded. Weight will be measured and 
recorded at each visit where vital signs are recorded as noted in the SoA. 
• Temperature (should be measured at the same location throughout the study), pulse rate, 
respiratory rate, and blood pressure will be assessed. 
• Blood pressure and pulse measurements will be assessed semisupine with a completely 
automated device. Manual techniques will be used only if an automated device is not available. 
• Blood pressure and pulse measurements will be preceded by at least 5 minutes of rest for the 
participant in a quiet setting without distractions (e.g., television, cell phones). 
• Vital signs will be measured in a semisupine position after 5 minutes rest and will include 
temperature, systolic and diastolic blood pressure, and pulse and respiratory rate. 
8.2.3 
Electrocardiograms  
• Single 12-lead ECG will be obtained as outlined in the SoA using an ECG machine that 
automatically calculates the HR and measures PR, QRS, and QT intervals and RR duration.  
• The 12-lead ECG recordings will be obtained after 10 minutes of rest in a semisupine position. 
• ECG results will be reviewed locally by the Investigator. In the event of findings that could 
represent clinically relevant cardiac issues (including but not limited to new or worsening 
arrhythmia, significant changes in ECG parameters, signs and/or symptoms that could represent 
cardiac events such as syncope, chest pain, etc.), additional evaluations can be performed per 
the Investigator’s clinical judgment (including but not limited to repeat ECGs, 
echocardiography, evaluation by a cardiologist). The printout of the ECG is to be signed, dated, 
and filed in the Investigator’s Site File along with a signed and dated copy (if the printouts are 
not on archive-quality paper). ECG tracings will be sent to the central reader electronically for 
processing. Final interpretation of ECGs may be made by the central ECG vendor. In addition, 
ECGs will also be stored digitally by the Sponsor. 
• In the OLE period, no ECG evaluation by central reader is required; however, ECGs will also 
be transmitted and stored digitally at the central location.

8.2.4 
Clinical Safety Laboratory Assessments  
• Blood and urine samples will be collected for the clinical laboratory tests listed in Appendix 5, 
at the time points listed in the SoA. All samples will be clearly identified.  
• Additional tests may be performed at any time during the study, as determined necessary by the 
Investigator or required by local regulations. 
• The tests will be performed by the central laboratory. See Appendix 5 for exceptions. 
• Local laboratory results are only required when central laboratory results are not available in 
time for study intervention administration and/or response evaluation. If a local sample is 
required, it is important that the sample for central analysis is obtained at the same time. 
Additionally, if the local laboratory results are used to make a study intervention decision or 
response evaluation, the results must be entered in the CRF. Immunoglobulin levels should not 
be done locally unless clinically indicated, as these results may lead to unblinding (see Section 
8.2.6). 
• The Sponsor will receive a list of the local laboratory normal ranges before shipment of study 
intervention(s). Any changes to the ranges during the study will be forwarded to the Sponsor or 
designated organization. 
• The Investigator will review each laboratory report, document their review, and record any 
clinically relevant changes occurring during the study in the AE section of the CRF. The 
laboratory reports will be filed with the source documents. 
• Laboratory/analyte results that could unblind the study will not be reported to investigative sites 
or other blinded personnel until the study has been unblinded. 
• Pregnancy testing (serum or highly sensitive urine, as required by local regulations) will be 
conducted at monthly intervals during study intervention administration. 
• Pregnancy testing (serum or highly sensitive urine, as required by local regulations) will be 
conducted at the end of relevant systemic exposure of the study intervention and correspond 
with the time frame for female participant contraception in Section 5.1. 
• Reflex analysis testing for HBV DNA by PCR will be conducted for participants who are anti-
hepatitis B surface antibody positive and/or anti-hepatitis B core antibody positive at Screening 
(see Exclusion Criterion 34). Whole blood samples of approximately 4 mL will be collected at 
the times specified in SoA. 
8.2.5 
Pregnancy  
Pregnancy testing (urine or serum as required by local regulations) should be conducted as 
summarized in the SoA (see Section 1.3) during intervention. 
Urine pregnancy testing will be performed at home or at the site. Urine pregnancy test kits will be 
provided to the participants at site visits. The Investigator and/or delegated site staff will train the 
relevant participants to self-administer the urine pregnancy test, and will contact the participant by 
telephone to confirm completion of urine pregnancy testing and discuss results.

8.2.6 
Immunoglobulin levels  
Blood samples for Ig levels (IgM, IgA, IgG, and IgE) will be collected as noted in the SoA (see 
Section 1.3). 
Samples will be analyzed by the central laboratory selected by the Sponsor. Samples will be 
collected, labeled, processed, stored, and shipped according to the instructions in the Laboratory 
Manual. 
Results will not be disclosed to the sites, Sponsor, or representative prior to database lock relative 
to the PA to avoid unblinding. However, the IDMC will have access to these data as applicable. 
8.2.7 
Columbia-Suicide Severity Rating Scale  
The C-SSRS will be used for prospective suicidality assessment. C-SSRS is a tool used to assess 
the lifetime suicidality of a participant and to track suicidal events through the treatment. The 
structured interview prompts recollection of suicidal ideation, including the intensity of the 
ideation, behavior and attempts with actual/potential lethality. 
The scale will be administered by the Treating Investigator (or designee) at the timepoints 
indicated in the SoA (see Section 1.3). The C-SSRS “Screening/Baseline” will be collected at 
Screening and Baseline and the C-SSRS “since last visit” will be collected at subsequent visits. 
Participants who answer “yes” to any suicidal behavior questions or to suicidal ideation questions 
4 or 5 on the C-SSRS during the study should be referred for appropriate psychiatric care. The 
decision to discontinue the participant from the study should be taken by the Investigator in 
conjunction with the mental health provider. Any mental health issues considered to be life 
threatening should be recorded as appropriate. 
Please note: assessing the risk of suicide is a difficult and complex task when applied to the 
individual participant. Certainly, no single clinical scale can replace a thorough medical 
examination and suicide risk assessment. Ultimately, the determination of the presence of 
suicidality depends on clinical judgment. 
8.2.8 
Independent Data Monitoring Committee, Hepatology 
Assessment Committee, Endpoint Adjudication Committee, 
and Study Steering Committee  
Independent Data Monitoring Committee 
An IDMC will be formed for this study to monitor interim safety and disease activity data on a 
regular basis to ensure ongoing surveillance of participant safety and to monitor the conduct of the 
study to protect its integrity, including recommendations about additional monitoring measures or 
risk mitigation procedures that may be deemed necessary to protect the study participants. After 
consideration, the Sponsor will inform the IDMC of any decision that will be taken in response to 
the IDMC recommendations. The IDMC will consist of a minimum of at least 3 expert members 
who are independent of the Sponsor. The members will be appointed by the Sponsor based on their

expertise in biostatistics, MS, and additional members with expertise in hepatology. All IDMC 
members will have experience in the conduct of clinical studies. Members will not be Investigators 
in the study, nor will they have any conflict of interest with the Sponsor. Sponsor representatives 
and study Investigators are not eligible for membership on the IDMC. Details regarding IDMC 
roles, responsibilities, activities, and possible recommendations will be provided in a separate 
IDMC charter. 
Hepatology Assessment Committee 
A HAC was formed to evaluate cases of possible DILI and to render ongoing opinion on overall 
DILI risk for evobrutinib. The DILI cases are to be suspected if at least one of the following criteria 
are met: 
a.) ALT or/and AST elevations > 8 × ULN;  
b.) ALT or/and AST elevations between > 5 × ULN and ≤ 8 × ULN;  
c.) Total bilirubin > 2 × ULN;  
d.) Total bilirubin > 2 × ULN with ALT or AST > 3 × ULN;  
e.) Acute or chronic hepatic failure, fibrosis, cirrhosis, and other liver damage-related conditions;  
f.) Any other case that might point to suspected DILI, based on Investigator assessment.  
HAC members will review case summaries including but not limited to clinician assessment, IMP 
exposure, laboratory assessments, hepatologist reports, medical history, and prior and concomitant 
medication to evaluate cases of suspected DILI. HAC will make recommendation to escalate cases 
to inform the IDMC and will advise IDMC on whether benefit/risk profile of evobrutinib requires 
changes based on their review. The HAC is composed of external hepatologists with the requisite 
scientific, and medical experience in review of suspected DILI cases. HAC members are 
independent from the Clinical Study Team and the development program team and are blinded to 
treatment assignments. Details regarding HAC roles, responsibilities, activities, and possible 
recommendations will be provided in a separate HAC charter. 
Endpoint Adjudication Committee 
An EAC will be formed for centralized, blinded review and determination of qualified relapses 
during DBTP and DBE (see Section 8.1.1.1). The EAC will be comprised of subject matter experts 
convened for the purpose of ensuring consistency across study sites and to allow for an unbiased 
endpoint assessment. Sponsor representatives and study Investigators are not eligible for 
membership on the EAC. The EAC will be managed by a central vendor; the vendor will be under 
contract to the Sponsor. Specific membership, roles, and responsibilities, required source

documentation, data format, details about review process, and procedures and timing of meetings 
will be addressed in a separate EAC charter. 
No EAC will be maintained after the DBTP and DBE have ended as relapses will be qualified by 
Treating Investigators in the OLE period. 
Study Steering Committee 
An SSC will provide direction and oversight to the study from an Investigator’s perspective, 
including protocol creation and amendments, study execution, and evaluation of study results at 
the end of study. Investigators in this clinical study and other experts who are not otherwise 
involved in the study may serve on this committee. 
8.3 
Adverse Events and Serious Adverse Events  
The definitions of an AE and a SAE are in Appendix 4. 
The Investigator and any qualified designees (e.g., Sub-Investigators) are responsible for detecting, 
documenting, and recording events that meet the definition of an AE or SAE. The Investigator 
remains responsible for following up AEs that are serious or that caused the participant to 
discontinue study intervention, as specified in Section 8.3.3. 
Requests for follow-up will usually be made via the Study Monitor, although in exceptional 
circumstances the global patient safety department may contact the Investigator directly to obtain 
further information or to discuss the event. 
8.3.1 
Time Period and Frequency for Collecting Adverse Event and 
Serious Adverse Event Information  
The AE reporting period for safety surveillance begins when the participant is initially included in 
the study (date of first signature of informed consent/date of first signature of first informed 
consent) and continues until the Safety Follow-up Visit. 
Any SAE assessed as related to study intervention must be recorded and reported, as indicated in 
Appendix 4, whenever it occurs, irrespective of the time elapsed since the last administration of 
study intervention. 
The method of recording, evaluating, and assessing causality of AEs (including SAEs) and the 
procedures for completing and transmitting SAE reports are in Appendix 4. 
8.3.2 
Method of Detecting Adverse Events and Serious Adverse 
Events  
At each study visit, the participant will be queried on changes in his or her condition. During the 
reporting period, any unfavorable changes in the participant’s condition will be recorded as AEs, 
regardless if reported by the participant or observed by the Investigator.

Complete, accurate and consistent data on all AEs experienced for the duration of the reporting 
period (defined below) will be reported on an ongoing basis in the appropriate section of the CRF. 
All SAEs and nonserious AESIs must be additionally documented and reported using the 
appropriate Report Form as specified in Appendix 4. 
8.3.3 
Follow-up of Adverse Events and Serious Adverse Events  
AEs are recorded and assessed continuously throughout the study, as specified in Section 8.3.1 
and are assessed for their outcome at the Safety Follow-up Visit. All SAEs ongoing at the Safety 
Follow-up Visit must be monitored and followed up by the Investigator until stabilization or until 
the outcome is known, unless the participant is documented as “lost to follow-up”. Reasonable 
attempts to obtain this information must be made and documented. It is also the responsibility of 
the Investigator to ensure that any necessary additional therapeutic measures and follow-up 
procedures are performed. Further information on follow-up procedures is given in Appendix 4. 
8.3.4 
Regulatory Reporting Requirements for Serious Adverse 
Events  
The Sponsor will send appropriate safety notifications to Health Authorities in accordance with 
applicable laws and regulations. 
The Investigator must comply with any applicable site-specific requirements related to the 
reporting of SAEs (particularly deaths) involving study participants to the IEC/IRB that approved 
the study. 
In accordance with ICH GCP, the Sponsor/designee will inform the Investigator of findings that 
could adversely affect the safety of participants, impact the conduct of the study, or alter the 
IEC’s/IRB’s approval/favorable opinion to continue the study. In line with respective regulations, 
the Sponsor/designee will inform the Investigator of AEs that are both serious and unexpected and 
considered to be related to the administered product (“suspected unexpected serious adverse 
reactions” or SUSARs). The Investigator should place copies of Safety Reports in the Investigator 
Site File. National regulations regarding Safety Report notifications to Investigators will be 
considered. 
Individual Case Safety Reports will be prepared for SUSARs according to local regulatory 
requirements and Sponsor policy and forwarded to Investigators within 15 days. 
An Investigator or sub-investigator who receives an Individual Case Safety Report describing a 
SUSAR or other specific safety information (e.g., Emerging Safety Issue Report, summary or 
listing of SAEs/SUSARs) from the Sponsor will review the safety reports and confirm completion 
of this review. This information will be filed it in the Investigator’s Site File, and the IRB/IEC will 
be notified, if appropriate, according to applicable local laws/regulations and site Standard 
Operating Procedures. 
When specifically required by regulations and guidelines, the Sponsor/designee will provide 
appropriate Safety Reports directly to the concerned lead IEC/IRB and will maintain records of 
these notifications. When direct reporting is not clearly defined by national or site-specific

regulations, the Investigator will be responsible for promptly notifying the concerned IEC/IRB of 
any Safety Reports provided by the Sponsor/designee and of filing copies of all related 
correspondence in the Investigator Site File. 
For studies covered by the European Directive 2001/20/EC, the Sponsor’s responsibilities 
regarding the reporting of SAEs/SUSARs/Safety Issues will be carried out in accordance with that 
Directive and with the related Detailed Guidance documents. 
8.3.5 
Pregnancy  
Details of all pregnancies in female participants and female partners of male participants will be 
collected after the start of study intervention and until the Safety Follow-up Visit. 
If a pregnancy is reported, the Investigator will inform the Sponsor within 24 hours of learning of 
the pregnancy and will follow the procedures specified below for collection of pregnancy 
information. 
Abnormal pregnancy outcomes (e.g., spontaneous abortion, fetal death, stillbirth, congenital 
anomalies, ectopic pregnancy) are considered SAEs. 
Collection of Pregnancy Information 
Male participants with partners who become pregnant: 
• The Investigator will attempt to collect pregnancy information on any male participant’s female 
partner, who becomes pregnant while the participant is in this study. This applies only to 
participants who receive study intervention. 
• After obtaining signed consent from the pregnant female partner directly, the Investigator will 
record the pregnancy information on the appropriate form and submit it to the Sponsor within 
24 hours of learning of the pregnancy. The female partner will also be followed to determine 
the outcome of the pregnancy. Information on the status of the mother and child will be 
forwarded to the Sponsor. Generally, the follow-up will be no longer than 6 to 8 weeks 
following the estimated delivery date. Any termination of the pregnancy will be reported 
regardless of fetal status (presence or absence of anomalies) or indication for the procedure. 
Female Participants who become pregnant:  
• The Investigator will collect pregnancy information on any female participant who becomes 
pregnant while she is in the study. The initial information will be recorded on the appropriate 
form and submitted to the Sponsor within 24 hours of learning of the pregnancy. 
• The participant will be followed to determine the outcome of the pregnancy. The Investigator 
will collect follow-up information on the participant and the neonate, and the information will 
be forwarded to the Sponsor. Generally, follow-up will not be required for longer than 6 to 8 
weeks beyond the estimated delivery date. Any termination of pregnancy will be reported, 
regardless of fetal status (presence or absence of anomalies) or indication for the procedure. 
• While pregnancy itself is not considered to be an AE or SAE, any pregnancy complication or 
elective termination of a pregnancy for medical reasons will be reported as an AE or SAE.

• A spontaneous abortion (occurring at <22 weeks gestational age) or stillbirth (occurring at >22 
weeks gestational age) is always considered to be an SAE and will be reported as such. 
• Any poststudy pregnancy related SAE considered reasonably related to the study intervention 
by the Investigator will be reported to the Sponsor as specified in Section 8.3.4. While the 
Investigator is not obligated to actively seek this information in former study participants, he or 
she may learn of an SAE through spontaneous reporting. 
• Any female participant who becomes pregnant while participating in the study will discontinue 
study intervention. Participants who intend to become pregnant during the study will also 
discontinue study intervention. As a pregnant participant may have received teriflunomide and 
due to the prolonged half-life of teriflunomide, an AEP should be performed and a teriflunomide 
level < 0.02 mg/L has to be reached (for more details see Appendix 8).  
8.4 
Treatment of Overdose  
For this study, any dose of study intervention greater than the highest total daily dose included in 
the protocol or planned for a participant in the study within a 24-hour time period - 6 hours will be 
considered an overdose. 
The Sponsor does not recommend specific treatment for an overdose if not associated with any 
clinical signs/symptoms, but assistive/supportive measures, as necessary, should be provided. 
However, if there are clinical signs/symptoms then AEP should be performed as described in 
Appendix 8. 
Even if it not associated with an AE or a SAE, any overdose is recorded in the CRF and reported 
to drug safety in an expedited manner. Overdoses are reported on a SAE Report Form, following 
the procedure in Appendix 4, section on Reporting Serious Adverse Events and Adverse Events 
of Special Interest. 
8.5 
Pharmacokinetics  
The following PK parameters will be calculated, when appropriate: 
 
Symbol 
Definition 
AUC 
Area under the plasma concentration-time curve 
CL/f 
The apparent total body clearance of study intervention following extravascular administration 
Cmax 
Maximum evobrutinib concentration  
Vz/f 
The apparent volume of distribution during the terminal phase following extravascular 
administration 
DBTP  
• Whole blood samples of approximately 2 mL will be collected for measurement of plasma 
concentrations of evobrutinib, as specified in the SoA. The actual date and time (24-hour clock 
time) of each sample will be recorded to calculate actual time elapsed since the prior dose 
administration. The sampling timing may be altered during the study based on newly available

data (e.g., to obtain data closer to the time of peak plasma concentrations) to ensure appropriate 
monitoring. 
• The exact date/time of sample collection and drug administration must be recorded in the eCRF 
and will be used in the calculation of PK parameters. Time deviations from planned PK 
sampling times will not be considered a protocol deviation provided the exact date/time of 
sample collection and drug administration are recorded in the eCRF. 
• For the PK substudy, participants (N = 75) must meet the inclusion/exclusion criteria as 
described for other study participants and should complete all safety and efficacy activities as 
described for other study participants. For the PK substudy participants, additional whole blood 
samples (37) of approximately 2 mL will be collected for measurement of plasma 
concentrations of evobrutinib, as specified in the SoA. The actual date and time (24-hour clock 
time) of each sample will be recorded to calculate actual time elapsed since the prior dose 
administration.  
• The quantification of evobrutinib in plasma will be performed using a validated assay method. 
Concentrations will be used to evaluate the PK of evobrutinib. 
• Remaining samples collected for analyses of evobrutinib concentration may also be used to 
evaluate safety or efficacy aspects related to concerns arising during or after the study. 
• Details on processes for collection and shipment of these samples are in the Laboratory Manual. 
Retention time and possible analyses of samples after the end of study are specified in the 
respective ICF. 
• Evobrutinib concentration information that may unblind the study will not be reported to 
investigative sites or blinded personnel until the study has been unblinded. As samples from 
participants randomized to teriflunomide will not be analyzed for plasma concentrations of 
evobrutinib, measurements of evobrutinib concentration will be performed by unblinded 
analysts as detailed in Section 6.3.2. 
• All samples collected for PK, as noted in the SoA, still within the known stability of the 
evobrutinib at the time of receipt by the bioanalytical laboratory will be analyzed. 
DBE and OLE periods 
• No blood samples for PK analysis will be collected from participants enrolled in the DBE and 
OLE periods. 
See Section 9.4.3.1 for further details of the PK analysis. 
8.6 
Pharmacodynamics  
• DBTP PD Substudy - Blood samples will be collected for measurement of BTK Occupancy, 
cellular function, and cytokines (approximately 50 mL per visit) at the time points specified in 
the SoA from participants at selected sites in the DBTP PD substudy (N = 75). Participation in 
the substudy is mandatory (see Section 8.8 for details. 
• Details on processes for collection and shipment of these samples are in the Laboratory Manual. 
The Sponsor will store the samples in a secure storage space with adequate measures to protect

confidentiality. Retention time and possible analyses of samples after the end of study are 
specified in the respective ICF. 
8.7 
Pharmacogenetics  
• Where local regulations and IRB/IEC allow, approximately 4 mL blood (total) sample will be 
collected for DNA analysis from consenting participants. Participation in pharmacogenetic 
research is optional. Participants who do not wish to participate in the pharmacogenetic research 
may still participate in the study. 
• If not collected on Day 1 or a redraw is needed, the pharmacogenetic sample may be obtained 
at any other point of time during the study. 
• In the event of DNA extraction failure, a replacement sample for pharmacogenetic testing may 
be requested from the participant. Additional informed consent will not be required to obtain a 
replacement sample. 
• Appendix 6 provides further information on pharmacogenetic research. 
8.8 
Biomarkers  
• Collection of participant samples for biomarker research is also part of this study and is 
governed by the appropriate ICF. 
• DBTP and DBE: The following participant samples for biomarker research are required and 
will be collected from all participants enrolled in the DBTP and DBE. Collection times are 
specified in the SoA: 
• Blood samples will be tested for biomarkers of disease to evaluate disease activity or 
treatment response. 
• Blood samples may be tested for biomarkers of disease to evaluate the exposure-response 
relationship between PD biomarkers. 
• Blood samples may be tested for novel liver function biomarkers (e.g., protein, miRNA, etc.) 
to evaluate their activity with respect to predictivity and sensitivity of the novel biomarkers 
of hepatic function compared to traditional clinical chemistry endpoints. 
• Blood samples may be tested for gene expression/gene products to evaluate disease activity 
or treatment response. 
• Blood samples may be tested for impact on vaccinal responses 
• In addition, participant samples (i.e. blood and PGx) collected may be analyzed for 
biomarkers thought to play a role in pharmacokinetics, safety endpoints, MS disease 
progression, drug response, and treatment efficacy including, specific candidate 
genes/genome-wide analysis for genetic variations. Also, samples may be re-purposed or 
used for future research studies.

• Participants’ blood samples collected during the DBTP, DBE and OLE study may be re-
purposed to evaluate safety endpoints, MS disease progression, drug response, treatment 
efficacy, response to prophylactic vaccines, and/or future research, as specified in the ICF. 
• Up to approximately 840 mL total blood will be collected during the DBTP with an additional 
370 mL collected from participants in the PK/PD substudy. For participants in the DBE, up to 
approximately 420 mL of blood will be collected. For participants in the OLE, up to 
approximately 220 mL of blood will be collected, with an additional approximately 80 mL 
collected from participants in the OLE biomarker substudy. Further details are provided in the 
ICF and Laboratory Manual. 
• Details on processes for collection and shipment of DBTP, DBE and OLE samples are in the 
Laboratory Manual. The Sponsor will store the samples in a secure storage space with adequate 
measures to protect confidentiality. Retention time and possible analyses of samples after the 
end of study are specified in the respective ICF.  
8.8.1 
Biomarkers of Disease, Disease Activity and Progression, 
Drug-related Outcomes, and Treatment Response  
DBTP, DBE and OLE Blood Biomarker Substudy - Blood samples will be collected from all 
participants to assess the relationship between candidate disease biomarkers (e.g., cytokines, etc.) 
and disease activity and progression (e.g., NfL), drug-related outcomes (e.g., impact on vaccinal 
responses), and/or treatment response. Samples will be obtained predose as noted in the SoA. 
Biomarkers of disease may be measured at the analytical laboratory selected by the Sponsor using 
an appropriately validated bioanalytical method. 
8.8.1.1 
Neurofilament Light Chain  
Recently, NfL, a critical component of neurons, has been established as a marker of neuronal 
damage and has become a potential biomarker for treatment monitoring in MS. As 1 of 5 
neurofilament proteins, NfL contributes to the structural support of axons, and the maintenance of 
their size, shape, and integrity. Following axonal damage, NfL is released into the CSF and blood. 
In patients with MS, serum NfL concentrations correlate with relapses, disability worsening, MRI 
disease activity and brain volume loss (Kuhle 2016, Kuhle 2017, Disanto 2017, Piehl 2018, 
Novakova 2017, Barro 2018). Recently, the International Progressive MS Alliance received a 
Letter of Support from the US FDA encouraging additional studies evaluating NfL as a 
pharmacodynamic and/or response biomarker in early clinical trials involving patients with 
progressive MS. Consequently, serum NfL concentrations will be assessed in all participants 
enrolled in this study.

Novel Liver Function Biomarkers  
DBTP and DBE 
Blood samples will be collected from all study participants enrolled in the DBTP to evaluate the 
relationship of novel biomarkers (e.g., protein, miRNA, etc.) of hepatic function levels compared 
to standard clinical chemistry endpoints during the DBTP. Levels of novel biomarkers of hepatic 
function may be measured using various methods in samples collected from participants at time 
points noted in the SoA.  
Sampling for novel liver function biomarkers is performed in parallel with liver function test (LFT) 
clinical chemistry monitoring. To enable analysis of a variety of biomarkers, samples are needed 
both prior as well as during the occurrence of elevated liver enzymes. Samples will be collected 
from all participants, stored, and a subset may be analyzed retrospectively, as appropriate. In 
addition, samples (both plasma and serum) may be repurposed to evaluate disease activity and 
progression (e.g., NfL), drug-related outcomes (e.g., impact on vaccinal responses), treatment 
responses, role of EBV in MS and/or future research studies. 
8.8.2 
DBTP PD Substudy - Bruton’s Tyrosine Kinase Occupancy, 
Cellular Function, and Cytokines  
BTK occupancy, cellular function (e.g., B cell activation), and cytokines will be measured as part 
of the DBTP PD substudy (described in Section 8.6) in order to confirm the expected occupancy, 
which has been predicted based on data from healthy participants and participants from the 
Phase II RMS study (MS200527_0086) and to further investigate the mechanism of action of 
evobrutinib. This study requires a complete set of samples to be obtained for the data to be 
evaluable. Complete sets of samples will be obtained from participants (N = 75) from selected sites 
which can provide appropriate samples. A larger number of participants may be sampled to 
account for participant drop-outs or the collection of incomplete sets of samples. 
Samples (predose) will be collected as noted on the SoA. One sample will be collected at Screening 
for assay performance verification. 
Samples may be analyzed by the analytical laboratory selected by the Sponsor using an 
appropriately validated bioanalytical method. 
8.8.3 
OLE Blood Biomarker PD Substudy – Biomarkers of Disease 
Activity, Progression and Response to Drug  
OLE - Blood samples will be collected from a subset of participants to evaluate the effect of 
extended evobrutinib treatment on biomarkers associated with disease progression (e.g., NfL), 
disease activity, drug-related outcomes (e.g., immune cell frequencies [TBNK assay] and Ig 
levels), candidate disease biomarkers (e.g., cytokines), and/or treatment responses. Samples will 
be obtained from participants (N = ~750; ~50% anticipated to be treated with evobrutinib and 
~50% with teriflunomide throughout the DBE at selected sites and participants will be selected in 
a blinded fashion. Due to the limited stability windows of the TBNK and Ig assays, the samples 
analyses will be performed before the study is unblinded. However, study team members will

remain blinded to any results and not view the data until the study is unblinded. Assays involving 
biomarkers of disease will only be performed after the study is unblinded.  
Participation in the OLE Blood Biomarker Substudy for biomarker research is optional. 
Participants who do not wish to participate in the biomarker research portion (i.e., blood sample 
collection) of the study may still participate in the MRI substudy.  
The following samples for biomarker research will be collected from a subset of participants. 
Collection times are specified in the SoA: 
• Blood samples will be tested for biomarkers of disease to evaluate disease activity or treatment 
response. (e.g., NfL). 
• Blood samples will be tested for immune cell frequencies (e.g., T cells, B cells and NK cells). 
• Blood samples will be tested for Ig levels (IgM, IgA, IgG, and IgE). 
• In addition, participants' samples may be repurposed to evaluate drug-related outcomes, 
treatment responses, role of EBV in MS, and/or for future research, as specified in the ICF. 
Samples (predose) will be collected as noted on the SoA (see Section 1.3).  
Samples will be analyzed by an analytical laboratory selected by the Sponsor using an 
appropriately validated bioanalytical method. 
For details describing the MRI substudy, please refer to Section 8.1.2  
8.8.4 
Gene Expression  
DBTP and DBE 
Blood samples for gene expression analysis will be collected, except from participants in countries 
where collection of samples is not allowed, predose at time points noted in the SoA from all 
participants enrolled in the DBTP. These samples should be obtained after the assessment of vital 
signs in all participants (where allowed by local regulations). The actual date and time of each 
sample will be recorded. Samples may be analyzed by an analytical laboratory selected by the 
Sponsor using an appropriately validated bioanalytical method. The purpose of this analysis is to 
test whether potential differences in expression of specific genes may be linked to PK, safety 
endpoints, drug response, and treatment efficacy. 
OLE  
For participants enrolled in the OLE, blood samples for gene expression analysis will not be 
collected.

Statistical Considerations  
9.1 
Statistical Hypotheses  
9.1.1 
Statistical Hypotheses Related to Primary Objective  
The primary endpoint, ARR based on up to 156 weeks of follow-up and qualified relapse events 
from participants enrolled in the present study, will be assessed for superiority via a 1-sided test 
of the null hypothesis H0: rRR ≥ 1, where rRR denotes qualified relapse rate ratio comparing 
evobrutinib to teriflunomide. The alternative hypothesis is H1: rRR < 1. The rRR effect measure 
will be estimated from a NB model for qualified relapse count that adjusts for covariates based on 
stratification factors.  
9.1.2 
Statistical Hypotheses Related to Secondary Objectives  
There are 6 efficacy secondary endpoints and 2 HRQoL secondary endpoints:  
• time to first occurrence of 12-week CDP based on up to 156 weeks of follow-up (pooled) 
• time to first occurrence of 24-week CDP based on up to 156 weeks of follow-up (pooled) 
• time to first occurrence of 24-week CDI based on up to 156 weeks of follow-up (pooled) 
• CFB in PROMIS PF score over 96 weeks (pooled) 
• CFB in PROMIS Fatigue score over 96 weeks (pooled) 
• total number of T1 Gd+ lesions based on all available MRI scans  
• number of new or enlarging T2 lesions on the last available MRI scan relative to the baseline 
MRI scan  
• NfL concentration level at Week 12. 
The secondary endpoint, time to 12-week CDP (pooled), will be assessed for superiority via a 1-
sided stratified logrank test of the null hypothesis H0: Se(t) ≤ Sc(t), where Se(t) denotes the survival 
function for time to 12-week CDP in the experimental (evobrutinib) group, Sc(t) denotes the

survival function for time to 12-week CDP in the control (teriflunomide) group, and the variable t 
denotes time since randomization. The alternative hypothesis is H1: Se(t) > Sc(t). Strata in the 
logrank test will be based on randomization strata and study ID. The secondary endpoint time to 
24-week CDP (pooled) will be analyzed similarly, with a similar null hypothesis tested. 
The secondary endpoint, time to 24-week CDI (pooled), will be assessed for superiority via a 1-
sided stratified logrank test of the null hypothesis H0: Se(t) ≥ Sc(t), evaluated for the participants 
with baseline EDSS ≥ 2.0, where Se(t) denotes the survival function for time to 24-week CDI in 
the experimental (evobrutinib) group, Sc(t) denotes the survival function for time to 24-week CDI 
in the control (teriflunomide) group, and the variable t denotes time since randomization. The 
alternative hypothesis is H1: Se(t) < Sc(t). Strata in the logrank test will be based on randomization 
strata and study ID. 
The secondary endpoint, CFB in PROMIS PF score over 96 weeks (pooled), will be assessed for 
superiority via a 1-sided test of the null hypothesis H0: ΔPF ≤ 0, where ΔPF denotes difference in 
average PROMIS PF score CFB least-squares means, comparing evobrutinib to teriflunomide, 
with average taken over Weeks 72, 84, and 96, based on pooled data (higher score corresponds to 
improved physical function). The alternative hypothesis is H1: ΔPF > 0. Covariates in the model 
used to model CFB will be based on randomization strata and study ID. The secondary endpoint 
CFB in PROMIS Fatigue score over 96 weeks (pooled) will be analyzed similarly, based on the 
null hypothesis H0: ΔFatigue ≥ 0 (higher score corresponds to more fatigue), with the exception that 
the average will be taken over Weeks 48, 60, 72, 84, and 96. 
The secondary endpoint, total number of T1 Gd+ lesions based on all available MRI scans, from 
participants enrolled in the present study, will be assessed for superiority via a 1-sided test of the 
null hypothesis H0: lRR ≥ 1, where lRR denotes lesion rate ratio comparing evobrutinib to 
teriflunomide. The alternative hypothesis is H1: lRR < 1. The lRR effect measure will be estimated 
from a NB model for total number of T1 Gd+ lesions that adjusts for covariates based on 
stratification factors, with offset based on number of available scans.  
The secondary endpoint number of active T2 lesions on the last available MRI scan relative to the 
baseline scan, will be analyzed similarly, with a similar null hypothesis tested, with the exception 
that the offset will be based on the time (in years) between the last available scan and the baseline 
scan. 
The secondary endpoint, NfL concentrations at 12 weeks, will be assessed for superiority via a 1-
sided test of the null hypothesis H0: GMe≤GMc, where GMe denotes the Geometric Mean estimate 
at 12 weeks in the experimental (evobrutinib) group, and GMc denotes the Geometric Mean 
estimate at 12 weeks in in the control (teriflunomide) group. The alternative hypothesis is 
H1: GMe>GMc.

Sample Size Determination  
9.2.1 
Sample Size for Primary Endpoint: ARR  
The sample size is estimated based on the primary endpoint, ARR up to 156 weeks, under the 
assumption that participants are followed for an average of 102 weeks. The ARR at 102 weeks

among participants receiving evobrutinib is estimated to be 0.13 (NB dispersion parameter ≈ 2.5), 
as compared with 0.23 (NB dispersion parameter ≈ 2.5) among participants receiving the control 
treatment, teriflunomide. This represents a reduction in qualified relapse rate of 43% due to 
evobrutinib relative to teriflunomide. A 1-sided test of superiority based on the qualified relapse 
rate ratio from a NB model for qualified relapse count, H0: rRR ≥ 1.0, H1: rRR < 1.0, requires an 
evaluable sample size of 359 participants per group, followed for 102 weeks, to provide 90% 
power, assuming a 1-sided significance level of 0.025 for the evobrutinib versus teriflunomide 
comparison. To account for a drop-out rate of 20% over 2 years (i.e., normal drop-out expected in 
an MS trial in the absence of the escalating crisis in Eastern Europe), the enrollment per group is 
targeted to be 449 participants, resulting in a targeted enrollment of 898 participants. 
The assumption for evobrutinib ARR is based on 48-week data from the Phase II study of 
evobrutinib in RMS, in which the highest dose, 75 mg twice daily administered under fasted 
conditions, resulted in an ARR of 0.11 (95% CI: 0.04, 0.25). Due to the wide CI, an estimate of 
0.13 is assumed for evobrutinib in Phase III study powering. The assumption of 0.23 for 
teriflunomide ARR is based on recent Phase III studies (ASCLEPIOS I and II), wherein ARR 
ranged from 0.22 to 0.25 (Hauser 2020). The assumption of 2.5 for the dispersion parameter is 
derived from point and CI estimates for ARR from active treatment groups of recent Phase III 
studies and modeling of relapse data from the Phase II study of evobrutinib. If the distribution of 
relapse count is more disperse than assumed (i.e., dispersion ≈ 3.0 in both groups), the power 
provided by an enrolled sample size of 449 participants per group will be reduced from 90% to 
87.4%. 
The PA is to be triggered when the primary endpoint (ARR) in the present study (i.e., 
MS200527_0080), the primary endpoint in the second Phase III study (i.e., MS200527_0082), and 
the important secondary endpoint (12-week CDP pooled) are adequately powered. The power 
associated with the ARR endpoint depends on the information collected, defined as the reciprocal 
of the variance of the qualified relapse ratio estimate (evobrutinib versus teriflunomide), as in a 
group sequential design. The information for the qualified relapse rate ratio based on a negative 
binomial model (as per Appendix 5 of the ASCLEPIOS I/II protocol, available as Supplementary 
Material to Hauser 2020) is given by: 
Equation 9.2.1: Information I = [1/n {1/(λ1 T) + 1/(λ2 T) + 2 γ}]-1 
where n = evaluable sample size per group, T is the common follow-up time, λ1 is ARR for 
evobrutinib, λ2 is ARR for teriflunomide, and γ is the dispersion parameter (γ > 0). The 
assumptions for this study are n = 359, T = 1.97 years (i.e., average follow-up time of 102 weeks), 
λ1 = 0.13, λ2 = 0.23, and γ = 2.5. When the study has accrued Information I=32.3, the test of the 
qualified relapse rate ratio, comparing evobrutinib to teriflunomide at the 1-sided 0.025 alpha 
level, is powered at 90%.

9.2.2 
Sample Size for Secondary Endpoint: 12-week CDP  
A total of 149 events (defined as 12-week CDP) from the pooled studies is required to provide 
71.5% power to detect hazard ratio = 0.66 at the 1-sided significance level of 0.025-0.0252 = 
0.024375 (see Section 9.4.4.3). It is expected that these events will be achieved by following the 
1796 participants for up to 156 weeks, assuming a logrank test, 2-year CDP rate in the 
teriflunomide group of 15% (i.e., teriflunomide hazard rate of 0.0813), and 2-year drop-out rate of 
20%. 
The treatment effect of HR = 0.66 is justified by the assumption that evobrutinib has an impact on 
time to 12-week CDP similar to that of anti-CD20 therapies, and thus the HR reported in 
Hauser 2020, comparing ofatumumab to teriflunomide, applies to the treatment effect of 
evobrutinib relative to teriflunomide. The 2-year CDP rate in the teriflunomide group is also based 
on results reported in Hauser 2020. 
When the pooled studies have accrued 149 12-week CDP events, the test of the hazard ratio, 
comparing evobrutinib to teriflunomide at the 1-sided 0.024375 alpha level, is powered at 71.5%. 
The trial-wise and family-wise type-1 error will be preserved at the 0.025 1-sided level in the 
presence of multiple testing due to multiple endpoints (primary and secondary), as described in 
Section 9.4.4.3.  
Sample size and power calculations for the ARR and 12-week CDP endpoints were performed 
using the East v6.5 package and via simulation in R v.6.3.  
9.2.3 
Sample Size Considerations due to the Currently Escalating 
Crisis in Eastern Europe  
Initial enrollment was closed on 01 October 2021 with 1041 participants enrolled in 
Study MS200527_0080 and 1053 participants enrolled in Study MS200527_0082. These 
enrollment figures exceeded the original planned enrollment of 930 participants per study.  
The currently escalating crisis in Eastern Europe poses a challenge to the successful conduct of the 
MS200527_0080 and MS200527_0082 studies due to the large representation of this region in the 
initial enrollment. In the worst case scenario, all data from participants in the region affected by 
the crisis (Ukraine, Russian Federation, and Belarus) will be unable to be queried for cleaning 
purposes and will be considered unreliable. In that scenario, only 645 participants from 
MS200527_0080 and 487 participants from MS200527_0082 will be included in the PA, reducing 
ARR power from 90% to 77.1% and 65.1%, respectively.  
The study design introduced in Protocol Version 4.0 (i.e., variable treatment duration) decreased 
the required participants per study from 930 to 898. To ensure preservation of 90% power for the 
ARR per study, such that up to 898 participants per study have data sufficiently robust for the PA, 
enrollment will be re-opened. Up to 253 participants for MS200527_0080 and up to 
411 participants for MS200527_0082 will be recruited due to the impact on data quality of 
participants in the above mentioned regions. Participants that are in screening at the time when 
sufficient participant numbers have already been reached will still be allowed to be enrolled in the

study. As eligibility criteria are identical between initial and reopened enrollment periods, the 
newly enrolled participants are not expected to significantly impact key baseline and disease 
characteristics of the overall study population. 
Based on simulations that take a more precise approach to modeling dropout, the ARR for each 
study will be powered at 90% for a sample size of 887-909. Thus, under the worst-case scenario, 
the number of participants recruited to Studies MS200527 0080 and 0082 in the second phase of 
enrollment is expected to be 242 to 264 and 400 to 422, respectively. 
Throughout the currently escalating crisis in Eastern Europe, the Sponsor will assess the reliability 
and usability of efficacy and safety data from the affected regions, to determine what fraction, if 
any, of the participants’ data from these countries can robustly contribute to the study objectives 
evaluation and be accepted by Health Authorities. This will determine the extent of additional 
participants to be recruited in each study (i.e., up to 253 participants for Study MS200527_0080 
and up to 411 participants for MS200527_0082). Under the intermediate scenario where data from 
participants randomized in the crisis region are either included fully or censored due to 
unreliability, the final enrollment will be in the range of 1,041 to 1,294 participants for Study 
MS200527_0080 and 1,053 to 1,464 participants for Study MS200527_0082, where the lower 
limit of the range is the actual enrollment at the time of Protocol Version 4.0, and the upper limit 
is the expected enrollment under the worst-case scenario. The intermediate scenario assumes that 
the second phase of enrollment will be halted short of worst-case, based on an evaluation of 
information accrual within data assessed to be reliable. The decision to stop additional recruitment 
prior to reaching the pre-defined cap will be based solely on this assessment, in consultation with 
the study IDMC and Steering Committees. The Sponsor will work closely with the IDMC to 
safeguard the study integrity and the ability to reliably deliver on study objectives. 
9.2.4 
Sample Size of PK/PD Substudy  
Assuming within-participant coefficient of variation (CV) of 22.06% for AUCinf, 23% for AUCall, 
and 39.2% for Cmax, 20 evobrutinib treated participants are required to detect a difference of 
approximately 24% for AUC, and 42% for Cmax, at 80% power, using a 2-sided t-test with 
alpha = 5%. After accounting for 20% drop-out rate, the required sample size for the PK substudy 
is at least 50 participants. To align with the required sample size for the PD substudy, 
75 participants will be selected in a blinded fashion from participating sites. 
Assuming a positive correlation between % BTKO and % B cell activation inhibition at a given 
time point, 30 evobrutinib-treated participants are required to detect a Pearson correlation of 0.45 
at 80% power, using a 1-sided t test with alpha = 5%. Assuming a 19% drop-out (or missing 
sample) rate during the 24-week period over which PD assessments are made, the planned sample 
size for the PD substudy is 75 participants, selected in a blinded fashion from participating sites. 
The assumption on correlation is based on Phase I data in healthy volunteers exposed to one of 3 
evobrutinib regimens (25 mg once daily, 75 mg once daily, or 200 mg once daily), wherein a 
correlation of 0.689 between % BTKO and % B cell activation inhibition was observed at Day 7 
trough (MS200527_0017).

Populations for Analyses  
The analysis sets for the primary analysis of the DBTP are specified below. The final decision to 
exclude participants from any analysis population will be made during a blinded data review 
meeting prior to database lock for the PA and unblinding. 
Analysis Set 
Description 
Screening (SCR)  
All participants, who provided informed consent, regardless of the participant’s 
randomization and study intervention status in the study. 
Full Analysis Set (FAS)

analyzed per the intervention group to which they were randomized (i.e., intention-to-
treat principle). This analysis set will be used for sensitivity analyses of efficacy. 
Modified FAS (mFAS) 
All participants in FAS except those participants from Ukraine, Russian Federation, 
and Belarus lacking data robustness. This analysis set will be specified in the IAP prior 
to unblinding and will be used for the PA of efficacy.

to unblinding and will be used for the PA of safety. 
PK 
All participants who receive at least 1 dose of evobrutinib and have at least 
1 quantifiable evobrutinib plasma concentration at a scheduled PK time point postdose 
without any important deviations or events that may impact the quality of the data or 
alter the evaluation of PK. Participants who receive active control will not be included. 
PD 
All participants who receive at least 1 dose of evobrutinib or active control, have a

Statistical Analyses  
This section provides a description of the statistical methods to be used to analyze efficacy, safety, 
and other endpoints for the PA. Prior to locking the database, a detailed IAP will be finalized. 
Analyses of DBE and OLE endpoints will be described in separate IAPs. 
Unless otherwise specified, for the PA, the mFAS will be used for all efficacy analyses, PRO 
analyses, and reporting of demographic and Baseline characteristics and the mSAF will be used 
for all safety data reporting. 
For the PA, secondary objectives based on disability progression, disability improvement, and 
patient reported symptoms and functional status will be evaluated based on pooled data from the 
present study and the second Phase III study (i.e., MS200527_0082). 
The PA will be performed on all data until the PA trigger date.

9.4.1.1 
Efficacy Analyses Related to Primary Objective  
Per ICH E9(R1), Addendum on Estimands and Sensitivity Analysis in Clinical Trials (November 
2019), the primary estimand targeting the primary objective in this study is defined by the 
following attributes:  
• Variable (endpoint): The primary endpoint is ARR up to 156 weeks. Measurements on the 
participant-level are number of qualified relapses experienced by the participant and follow-up 
time over which those relapses occurred (potentially less than 156 weeks). 
• Treatment: The intervention of interest is evobrutinib 45 mg twice daily for up to 156 weeks 
and the alternative intervention is teriflunomide 14 mg once daily for up to 156 weeks. 
• Population: The population of participants targeted by the clinical question is defined by the 
inclusion/exclusion criteria. 
• Strategies for handling intercurrent events: In the absence of the currently escalating crisis 
in Eastern Europe, the main intercurrent event envisaged is discontinuation of assigned 
treatment. The strategy for dealing with this is Treatment Policy, which requires that the 
qualified relapse count up to 156 weeks post randomization be used, if available, regardless of 
treatment discontinuation. The Compositive Variable strategy is used to handle the intercurrent 
event of death attributable to MS or treatment. The While Alive strategy is used to handle the 
intercurrent event of death unattributable to MS or treatment. The intercurrent event of the crisis 
in Eastern Europe ("Ukraine crisis”) will be handled via the Hypothetical strategy; strategy 
details will be specified in the IAP prior to unblinding and after a careful evaluation of data 
robustness for participants from sites in the region affected by the crisis (Ukraine, Russian 
Federation, and Belarus). 
• Population-level summary: The population-level summary comparing the intervention groups 
is relapse rate ratio, based on an NB model for qualified relapse count, with terms for 
intervention group and randomization strata, with offset equal to log follow-up time (in years) 
over which the qualified relapses experienced by a participant are observed.

In accordance with Treatment Policy strategy, for participants discontinuing treatment, any 
qualified relapses occurring through Safety Follow-up will be included in the analysis up to 
156 weeks post randomization. For participants who have not been followed to 156 weeks post 
randomization, the missing data will be assumed to be MAR; treatment discontinuers will be 
assumed to experience relapse through 156 weeks post randomization at the same rate as treatment 
completers within the same intervention group and stratum. This is the assumption underlying the 
rate ratio estimator implemented by the NB model that uses observed relapse events and observed 
follow-up time for each participant, regardless of treatment completer/discontinuer status.  
In accordance with the Composite Variable strategy, for participants experiencing death 
attributable to MS or treatment, the death will be counted as a qualified relapse. In accordance with 
the While Alive strategy, for participants experiencing death unattributable to MS or treatment, 
the death will not be counted as a qualified relapse.  
In accordance with the Hypothetical strategy, for participants from sites in Ukraine, Russian 
Federation, and Belarus, the “Ukraine crisis” intercurrent event will lead to exclusion from the 
mFAS (i.e., hypothetical scenario in which participant was not recruited), or inclusion in the mFAS 
with censoring at the start of the crisis (i.e., hypothetical scenario in which crisis would not occur), 
or inclusion in the mFAS without censoring at the start of crisis, depending on the assessment of 
data robustness. Details of the Hypothetical strategy for handling the intercurrent event of the 
“Ukraine crisis” will be specified in the IAP prior to unblinding.  
The adjusted relapse rate ratio comparing evobrutinib to teriflunomide will be estimated from the 
NB model. The adjusted rate ratio, 95% 2-sided CI, and 1-sided p-value will be reported, together 
with adjusted ARR (and 95% CI) for each intervention group from the model, and unadjusted ARR 
(and 95% CI) for each intervention group estimated nonparametrically. The analysis of ARR will 
be based on data from this study alone.  
Unadjusted ARR up to 156 weeks is calculated by dividing the total number of qualified relapse 
events experienced by all participants in a given group through Week 156 by the person-time (in 
years) observed for those participants through Week 156. 
The covariates defined by randomization strata are region (4 levels: North America, Western 
Europe, Eastern Europe, Rest of World) and Baseline (Day 1) EDSS (2 levels: < 4.0, ≥ 4.0). The 
NB model assumes a common dispersion parameter for all participants, independent of 
intervention group or Baseline covariates. The adjusted relapse rate ratio estimate is given by 
exponentiation of the estimate for the treatment coefficient from the NB model. In the PA, only 
observed events and observation time will be included in the analysis; there will be no imputation 
of events for participants discontinuing study early. 
Sensitivity analyses of the primary estimand for the primary endpoint are specified in 
Section 9.4.1.3. 
The IAP will further specify rates, timings, and potential roles of intercurrent events, strategies for 
handling them, and potential consequences on the analyses and results.

9.4.1.2 
Efficacy Analyses Related to Secondary Objectives  
The hypotheses tested in support of secondary efficacy objectives are described, and the 
inheritance of alpha graphically depicted, in Section 9.4.4.3. 
The primary estimands targeting the secondary objectives in this study share some of the attributes 
of the primary estimand in Section 9.4.1.1, such as the treatment comparison attribute, the 
population attribute, and the strategy for dealing with the intercurrent events of treatment 
discontinuation and “Ukraine crisis.” Distinctive attributes of each estimand are described below 
for each secondary endpoint. 
Time to 12-week CDP, Time to 24-week CDP 
For the secondary efficacy endpoint, time to 12-week CDP (CDP based on EDSS), the Treatment 
Policy strategy requires that all EDSS data, up to 156 weeks post randomization, will be used if 
available, regardless of treatment discontinuation. In accordance with Treatment Policy strategy, 
for participants discontinuing treatment, all EDSS data through Safety Follow-up will be included 
in the analysis up to 156 weeks post randomization. The population-level summary comparing the 
intervention groups is 12-week CDP hazard ratio, based on a stratified Cox model for 12-week 
CDP hazard rate, with terms for intervention group, strata defined by randomization strata and 
study ID, and where the data are pooled from the mFAS of the present study and the FAS of the 
second Phase III study.  
Participants who did not experience 12-week CDP by 156 weeks post randomization, by time of 
PA trigger, by time of early study discontinuation, or before being lost to follow-up, will be 
censored at the date of the last EDSS assessment during the 156 weeks post randomization. 
Censoring will be assumed to be noninformative for 12-week CDP, conditional on intervention 
group, randomization stratum, and study ID. This is the assumption underlying the hazard ratio 
estimator implemented by the stratified Cox model that uses observed follow-up time for each 
participant, regardless of treatment completer/discontinuer status, where participants are censored 
for 12-week CDP at the latest EDSS assessment.  
In accordance with the Composite Variable strategy, for participants experiencing death 
attributable to MS or treatment, the death will be counted as 12-week CDP. In accordance with the 
While Alive strategy, for participants experiencing death unattributable to MS or treatment, the 
death will not be counted as 12-week CDP. Details of the Hypothetical strategy for handling the 
intercurrent event of the “Ukraine crisis” will be specified in the IAP prior to unblinding.  
Per Protocol Version 3, prior to the completion of enrollment, an optional IA for BSSR was 
performed based on the secondary efficacy endpoint, time to 12-week CDP, with data pooled 
across the present study and the second Phase III study (see Section 9.4.4.1). Performed in August 
2021, the outcome of this IA for BSSR was a decision to not increase sample size.  
The PA of time to 12-week CDP will report the hazard ratio comparing evobrutinib to 
teriflunomide estimated via a stratified Cox model, 95% 2-sided CI, and 1-sided p-value for the 
stratified logrank test, together with a Kaplan-Meier estimate of cumulative probability of 
experiencing 12-week CDP over time for each intervention group. Prior to pooling, the validity of

pooling data across the present study and the second Phase III study will be assessed by reviewing 
consistency of demographics, Baseline characteristics, ARR and 12-week CDP results. 
The secondary endpoint, time to 24-week CDP, will be analyzed in the same manner as that of the 
12-week CDP endpoint. The primary estimand attributes for the time to 24-week CDP endpoint 
are the same as the primary estimand attributes for the time to 12-week CDP endpoint. 
Time to 24-week CDI 
For the secondary efficacy endpoint, time to 24-week CDI (CDI based on EDSS), the Treatment 
Policy strategy requires that all EDSS data, up to 156 weeks post randomization, will be used if 
available, regardless of treatment discontinuation. In accordance with Treatment Policy strategy, 
for participants discontinuing treatment, all EDSS data through Safety Follow-up will be included 
in the analysis up to 156 weeks post randomization. The population-level summary comparing the 
intervention groups is 24-week CDI hazard ratio, based on a stratified Cox model for 24-week CDI 
hazard rate, with terms for intervention group, strata defined by randomization strata and study ID, 
and where the data are pooled from participants in the mFAS of the present study and the mFAS 
of the second Phase III study who have baseline EDSS ≥ 2.0.  
Participants who did not experience 24-week CDI by 156 weeks post randomization, by time of 
PA trigger, by time of early study discontinuation, or before being lost to follow-up, will be 
censored at the date of the last EDSS assessment during the 156 weeks post randomization. 
Censoring will be assumed to be noninformative for 24-week CDI, conditional on intervention 
group, randomization stratum, and study ID. This is the assumption underlying the hazard ratio 
estimator implemented by the stratified Cox model that uses observed follow-up time for each 
participant, regardless of treatment completer/discontinuer status, where participants are censored 
for 24-week CDI at the latest EDSS assessment.  
In accordance with the While Alive strategy, for participants experiencing death (any cause), 
participants will be censored at time of death. Details of the Hypothetical strategy for handling the 
intercurrent event of the “Ukraine crisis” will be specified in the IAP prior to unblinding.  
The PA of time to 24-week CDI will report the hazard ratio comparing evobrutinib to teriflunomide 
estimated via a stratified Cox model, 95% 2-sided CI, and 1-sided p-value for the stratified logrank 
test, together with a Kaplan-Meier estimate of cumulative probability of experiencing 24-week 
CDI over time for each intervention group.  
CFB in PROMIS PF score over 96 weeks, CFB in PROMIS Fatigue score over 96 weeks 
For the secondary efficacy endpoint, CFB in PROMIS PF score over 96 weeks, the Treatment 
Policy strategy requires that the CFB in PROMIS PF score over 96 weeks post randomization be 
used if available, regardless of treatment discontinuation. The population-level summary 
comparing the intervention groups is difference in average least-squares means, based on a 
MMRM for CFB, with average taken over Weeks 72, 84, and 96, where the model includes terms 
for intervention group, visit, intervention group by visit interaction, Baseline score, randomization 
strata, and study ID, and where the data are pooled from the mFAS of the present study and the 
mFAS of the second Phase III study.

For participants with missing PROMIS PF data, the missing data will be assumed to be MAR; 
such participants will be assumed to have the same mean PROMIS PF score CFB trajectory 
through 96 weeks as participants with available data within the same intervention group and 
stratum, and having the same Baseline score and study ID. This is the assumption underlying the 
estimator of difference of average least-squares means implemented by the MMRM that uses 
observed score CFB data from each participant, regardless of treatment completer/discontinuer 
status.  
In accordance with the While Alive strategy, for participants experiencing death, all PROMIS PF 
data up to the time of death will be used in the analysis. Details of the Hypothetical strategy for 
handling the intercurrent event of the “Ukraine crisis” will be specified in the IAP prior to 
unblinding. 
The difference (comparing evobrutinib and teriflunomide) in average least-squares mean CFB, 
95% 2-sided CI, and 1-sided p-value will be reported. For each intervention group, the average 
adjusted least-squares mean score CFB and associated 95% 2-sided CI will be reported, as will the 
estimated cumulative distribution function for average score CFB.  
The secondary endpoint, CFB in PROMIS Fatigue score over 96 weeks, will be analyzed in the 
same manner as CFB in PROMIS PF score over 96 weeks, except that the average will be taken 
over Weeks 48, 60, 72, 84, and 96. The primary estimand attributes for these 2 endpoints are the 
same. 
Total number of T1 Gd+ lesions based on all available MRI scans, Number of new or 
enlarging T2 lesions on the last available MRI scan relative to the baseline MRI scan  
For the secondary efficacy endpoint, total number of T1 Gd+ lesions based on all available MRI 
scans, the Treatment Policy strategy requires that the lesion count over all available scans post 
randomization be used, if available, regardless of treatment discontinuation. Offset will be log total 
number of available scans. The population-level summary comparing the intervention groups is 
total lesion rate ratio, based on a NB model for lesion count, with terms for intervention group, 
randomization strata, and Baseline lesion activity, with offset equal to log number of total available 
scans over which the lesions experienced by a participant are observed. 
For participants missing one or more scans, the missing data will be assumed to be MAR; such 
participants will be assumed to experience lesions through planned end of treatment (i.e., PA 
trigger or 156 weeks, whichever occurs first) at the same rate as participants with available data 
within the same intervention group and stratum, and having the same Baseline lesion activity. This 
is the assumption underlying the rate ratio estimator implemented by the NB model that uses 
observed lesion count and number of scans giving rise to that count for each participant, regardless 
of treatment completer/discontinuer status. 
In accordance with the While Alive strategy, for participants experiencing death, all T1 Gd+ lesion 
data up to the time of death will be used in the analysis. Details of the Hypothetical strategy for 
handling the intercurrent event of the “Ukraine crisis” will be specified in the IAP prior to 
unblinding.

The adjusted lesion rate ratio comparing evobrutinib to teriflunomide estimated from the NB 
model, 95% 2-sided CI, and 1-sided p-value will be reported, together with adjusted lesion rate for 
each intervention group and associated 95% 2-sided CI. The analysis of total number of T1 Gd+ 
lesions will be based on data from the present study only.  
The secondary endpoint, number of new or enlarging T2 lesions on the last available MRI scan 
relative to the baseline MRI scan, will be analyzed in the same manner as total number of T1 Gd+ 
lesions based on all available MRI scans, except that the offset will be log of time between the 
baseline scan and last available scan (in years). The primary estimand attributes for these two 
endpoints are the same. 
Sensitivity analyses of the primary estimands of the secondary endpoints are specified in 
Section 9.4.1.3. 
Week 12 NfL Concentration 
For the secondary efficacy endpoint, Week 12 NfL concentration, the Treatment Policy strategy 
requires that all values of NfL concentrations be used if available, regardless of treatment 
discontinuation. The population-level summary comparing the intervention groups is difference in 
least-squares means, based on a MMRM for log(NfL concentration), where the model includes 
terms for intervention group, visit, intervention group by visit interaction, Baseline concentration 
and randomization strata.  
For participants with missing NfL concentration data, the missing data will be assumed to be MAR; 
such participants will be assumed to have the same mean NfL concentration trajectory through 
planned end of treatment (i.e., PA trigger or 156 weeks, whichever occurs first) as participants 
with available data within the same intervention group and stratum, and having the same Baseline 
concentration. This is the assumption underlying the estimator of difference of least-squares means 
through Week 12 implemented by the MMRM that uses observed NfL concentration data from 
each participant, regardless of treatment completer/discontinuer status.  
In accordance with the While Alive strategy, for participants experiencing death, all NfL 
concentration data up to the time of death will be used in the analysis. Details of the Hypothetical 
strategy for handling the intercurrent event of the “Ukraine crisis” will be specified in the IAP 
prior to unblinding. 
The difference (comparing evobrutinib and teriflunomide) in least-squares mean, 95% 2-sided CI, 
and 1-sided p-value will be reported. For each intervention group, the adjusted least-squares mean 
at Week 12 and associated 95% 2-sided CI will be reported.

9.4.1.3 
Sensitivity Analyses  
The following sensitivity analyses for the primary endpoint ARR up to 156 weeks will be detailed 
in the IAP: 
1. Analysis to evaluate the potential influence of informative treatment discontinuation 
according to discontinuation reason. If a participant’s discontinuation is unrelated to 
treatment (i.e., unrelated to efficacy or safety issues), the participant’s relapse count will 
be multiply imputed using ARR in the comparator group, for the interval between 
discontinuation and planned end of treatment (i.e., PA trigger or 156 weeks post 
randomization, whichever occurs first). If a participant’s discontinuation is related to 
treatment, relapse count will be multiply imputed at a rate higher than ARR in comparator 
group, for the interval between discontinuation and planned end of treatment. 
2. Analysis in which participants who discontinued treatment early during the 
Treatment Period without qualified relapse in the 30 days prior to discontinuation, are 
assumed to have a qualified relapse event at the date of discontinuation. 
3. Analysis in which additional covariates are included in the NB model, such as number of 
relapses occurring within 2 years prior to study entry, Baseline presence/absence of T1 
Gd+ lesions, prior MS treatment, and age, to evaluate the potential impact of model 
misspecification. 
4. Analysis to evaluate the impact of the currently escalating crisis in Eastern Europe. All 
participants in the FAS will be included, with consideration given to including a 
time-dependent covariate indicating whether the participant is under the stress of the crisis, 
which may be associated with increased frequency of relapses. 
For the primary estimand of the secondary endpoint, time to 12-week CDP, it is important to assess 
the sensitivity of results to the assumption that censoring is noninformative for 12-week CDP, 
conditional on intervention group, study ID, and stratum. The following sensitivity analyses for 
the secondary efficacy endpoint time to 12-week CDP will be detailed in the IAP: 
1. Analysis to evaluate the potential influence of informative treatment discontinuation, 
according to discontinuation reason or occurrence of initial progression event at last 
assessment. If a participant’s discontinuation is unrelated to treatment (i.e., unrelated to 
efficacy or safety issues) and no initial progression event occurred, the participant’s time 
to CDP will be multiply imputed using hazard rate in comparator group, for the interval 
between discontinuation and planned end of treatment (i.e., PA trigger or 156 weeks post 
randomization, whichever occurs first). If a participant’s discontinuation is related to 
treatment or an initial unconfirmed progression event occurred, the participant’s time to 
CDP will be multiply imputed using hazard rate higher than that in comparator group, for 
the interval between discontinuation and planned end of treatment. 
2. Analysis in which participants who discontinued treatment early during the 
Treatment Period after having an initial progression event, but prior to 12-week 
confirmation, are assumed to have a 12-week CDP event at the date of initial progression.

3. Analysis with additional covariates in the stratified Cox model, such as number of relapses 
occurring within 2 years prior to study entry, Baseline presence/absence of T1 Gd+ lesions, 
prior MS treatment, and age. 
4. Analysis to evaluate the impact of the currently escalating crisis in Eastern Europe. All 
participants in the FAS will be included, with consideration given to including a time-
dependent covariate in the model. 
Sensitivity analyses for time to 24-week CDP will be similar. 
Sensitivity analyses for the secondary endpoint time to 24-week CDI will be specified in the IAP. 
For the primary estimand of the secondary endpoint, PROMIS PF CFB, it is important to assess 
the sensitivity of results to the MAR assumption that participants with missing data have the same 
mean CFB trajectory through 96 weeks or PA trigger, whichever occurs first, as participants with 
complete data, conditional on intervention group, Baseline score, study ID, and stratum. The 
following sensitivity analysis for the secondary endpoint PROMIS PF score CFB over 96 weeks 
will be detailed in the IAP: 
1. Analysis to evaluate the potential influence of informative treatment discontinuation 
according to discontinuation reason. If a participant’s discontinuation is unrelated to 
treatment (i.e., unrelated to efficacy or safety issues), the participant’s score CFB at each 
timepoint will be multiply imputed using CFB distribution at that timepoint in comparator 
group, for the interval between discontinuation and 96 weeks post randomization or PA 
trigger, whichever occurs first. If a participant’s discontinuation is related to treatment, the 
participant’s score CFB at each timepoint will be multiply imputed using a worse CFB 
distribution at that timepoint than that in comparator group, for the interval between 
discontinuation and 96 weeks post randomization or PA trigger, whichever occurs first. 
2. Analysis to evaluate the impact of the currently escalating crisis in Eastern Europe. All 
participants in the FAS will be included, with consideration given to including a time-
dependent covariate in the model. 
Sensitivity analyses for PROMIS Fatigue score CFB over 96 weeks will be similar. 
For the primary estimand of the secondary endpoint, total number of T1 Gd+ lesions based on all 
available MRI scans, it is important to assess the sensitivity of results to the MAR assumption that 
participants with missing data experience lesions until planned end of treatment at the same rate 
as participants with complete data, conditional on intervention group, Baseline lesion activity, and 
stratum. The following sensitivity analysis for the secondary efficacy endpoint total T1 Gd+ 
lesions will be detailed in the IAP: 
1. Analysis to evaluate the potential influence of informative treatment discontinuation 
according to discontinuation reason. If a participant’s discontinuation is unrelated to 
treatment (i.e., unrelated to efficacy or safety issues), the participant’s lesion count will be 
multiply imputed using rate in comparator group, for the interval between discontinuation 
and planned end of treatment (i.e., PA trigger or 156 weeks post randomization, whichever 
occurs first). If a participant’s discontinuation is related to treatment, lesion count will be

multiply imputed at a rate higher than that in comparator group, for the interval between 
discontinuation and planned end of treatment. 
2. Analysis to evaluate the impact of the currently escalating crisis in Eastern Europe. All 
participants in FAS will be included, with consideration given to including a time-
dependent covariate in the model. 
The following supplemental analyses for the secondary efficacy endpoint total number of T1 Gd+ 
lesions based on all available MRI scans will be detailed in the IAP: 
1. Analysis wherein lesion count at a single scan is modeled as Poisson-distributed, with a 
random effect for participant, and terms for intervention group, randomization strata, and 
Baseline lesion activity. This model will compare treatment on the basis of conditional 
adjusted lesion rate ratio, where conditioning is on the random effect. 
Sensitivity and supplemental analyses for number of new/enlarging T2 lesions on the last available 
MRI scan relative to the baseline MRI scan, except that the offset in the model will be log time 
from baseline scan to last available scan (in years), in place of log number of scans. 
Sensitivity analyses for the secondary endpoint, NfL concentration at 12 weeks, will be specified 
in the IAP. 
Further details on sensitivity analyses of ARR, 12-week CDP, and other secondary efficacy 
endpoints, which incorporate available data from participants enrolled at sites in the currently 
escalating crisis regions in Eastern Europe, will be described in the IAP.

Other Analyses  
9.4.3.1 
Pharmacokinetic 
Parameters, 
Pharmacodynamic 
Parameters, Biomarkers  
PK, PD, and biomarker exploratory analyses will be specified in the IAP finalized before database 
lock. Integrated analyses across studies, such as the population PK analysis and PD analyses will 
be presented separately from the main CSR. 
In general, biomarkers and PD parameters assessed at planned visits and premature early 
discontinuation from treatment will be summarized in a manner similar to safety laboratory 
parameters.  
The PK and BTK occupancy data of the current study will be used for the development of 
population PK and BTK occupancy models (possibly in combination with the corresponding data 
of earlier studies, e.g., MS200527_0019, MS200527_0017, MS200527_0086, and/or others), to 
describe the PK and BTK occupancy time profiles for the participants in the study. Population PK 
model-based exposure metrics such as Cmax and AUC (from 0 to 24 hour) at steady state will be 
derived.  
The derived PK profiles and exposure metrics will be used to develop exposure-response models 
(longitudinal or cross-sectional) for MRI, efficacy, and safety endpoints. In particular, a 
cross-sectional model of ARR as a function of steady state AUC, a longitudinal repeated time to 
event (qualified relapse) model, a longitudinal model for EDSS, cross-sectional or longitudinal 
exposure-response models for MRI lesions (T1 Gd+ lesion and new or enlarging T2 lesion count), 
and a longitudinal (if possible) exposure-response model for ALT elevations, will be developed. 
Other endpoints of interest depending on the signals that will be detected based on the 
exploratory/inferential statistical analysis of the study data may also be included in the 
exposure-response analyses. 
Full details of the planned population PK/PD modeling and other exposure-related modeling will 
be described in the study IAP. The results of the corresponding analyses will be reported separately 
from the study CSR. 
9.4.3.2 
Demographics, Baseline Characteristics, Disposition, and 
Compliance

randomization, time (in years) since onset of MS symptoms, time (in years) since MS diagnosis, 
Baseline number of T1 Gd+ lesions, Baseline number of T2 lesions, and Baseline T2 lesion 
volume, prior MS study treatment will also be summarized. 
Disposition of participants (i.e., discontinuation from treatment by reason, discontinuation from 
study by reason) and compliance of participants to intervention will be summarized by intervention 
group using descriptive statistics. 
9.4.3.3 
Patient Reported Outcome Analyses  
The analysis of PROMIS PRO secondary endpoints is described in Section 9.4.1.2. A similar 
analysis will be performed for exploratory PRO score CFB endpoints. The exploratory endpoint, 
time to deterioration in PROMIS PF score confirmed at 12 weeks will be analyzed in a manner 
similar to that of time to 24-week CDP. 
9.4.3.4 
Health Resource Utilization  
For the exploratory endpoint HRU observed values at each visit and CFB to each postbaseline visit 
in HRU (doctor/home/emergency visits, hospitalizations, paid assistance, and missed work) will 
be summarized by time point and intervention group using descriptive statistics (mean, standard 
deviation, median, minimum/maximum, 25th and 75th percentile; 95% CI). 
9.4.3.5 
Analysis of Double-Blind Extension Period Endpoints  
Efficacy and HRQoL data collected during the DBE period will be analyzed as additional data to 
DBTP (i.e., baseline will be baseline of DBTP). Details will be provided in the IAP.  
Safety data collected during the DBE Period will be analyzed as described in Section 9.4.2. 
9.4.3.6 
Analysis of Open Label Extension Period Endpoints  
Efficacy and HRQoL data collected during the OLE Period will be summarized. Details will be 
provided in the IAP.  
Safety data collected during the OLE Period will be analyzed as described in Section 9.4.2. 
9.4.4 
Sequence of Analyses  
4 analyses are planned for the study: (1) an optional IA for BSSR based on the secondary endpoint 
12-week CDP, with data pooled across the present study and the second Phase III study, performed 
by the Sponsor, triggered when enrollment is nearing completion, (2) a PA, performed by the 
Sponsor after the PA database lock, with timing and endpoint evaluation as described in 
Section 9.4.4.2, (3) an analysis of all data from blinded periods at the end of DBE, performed by 
the Sponsor after the corresponding DBE database lock, (4) a final analysis, performed by the 
Sponsor after the final database lock, triggered when 100% of participants enrolled in the OLE 
Period complete the OLE, or discontinue prematurely from the OLE.

The PA of the present study (i.e., MS200527_0080) and the second Phase III study (i.e., 
MS200527_0082) will be triggered as described in Section 9.4.4.2.  
In addition, analyses will be performed at regular intervals for the purpose of safety monitoring by 
the IDMC, as described in the IDMC charter. 
9.4.4.1 
Optional Interim Analysis for Blinded Sample Size Re-
estimation  
Per Protocol Version 3, when enrollment was nearing completion, an optional IA for BSSR based 
on the secondary endpoint 12-week CDP may be performed by the Sponsor, using data pooled 
across studies. Only data relevant to 12-week CDP needed to be cleaned for the IA.  
Parametric distributions for time to 12-week CDP and time to censoring were fitted using blinded 
data pooled across studies. The resulting parameter estimates were used to estimate expected 
number of events given the originally planned sample size. If the expected number of events was 
less than the number required to power the 12-week CDP endpoint at 80%, consideration was to 
be given to increasing the sample size up to 25% so that the required number of events was 
achieved (Friede 2019). Performed in August 2021, the outcome of this IA for BSSR was a 
decision to not increase sample size. In the setting of superiority trials, an IA for BSSR has a 
minimal or non-existent effect on type-1 error inflation (Friede 2019). 
9.4.4.2 
Primary Analysis  
Based on an analysis of accumulating blinded data, the PA will be triggered for both studies 
simultaneously when all of the following conditions are met. 
• This study and the second Phase III study have individually collected ≥ 32.3 units of information 
for the primary ARR endpoint, where “Information” is defined below. At this timepoint both 
studies will provide ≥ 90% power for the detection of a 43.5% relative treatment effect on ARR 
in the primary statistical test at a 1-sided alpha level of 0.025.  
• In data pooled from the 2 studies, ≥ 149 12-week CDP events have been observed. At this 
timepoint, the combined studies have collected sufficient information to provide ≥ 71.5% power 
for the detection of 34% (hazard ratio = 0.66) relative reduction in risk of 12-week CDP in a 
logrank test at a 1-sided alpha-level of 0.025-0.0252 = 0.024375. 
• All participants have been treated for 24 weeks or discontinued prematurely. 
The default is that the PA will be triggered when all participants have been treated for 156 weeks 
or discontinued prematurely, if this occurs before the information for ARR and 12-week CDP 
event criteria are met. 
After protocol deviations are determined, and the database is locked for the PA, the drug codes 
will be broken and made available for the primary data analysis. All endpoints based on data from 
the DBTP until PA trigger date will be evaluated. This implies that the data related to 
End-of-DBTP visits occurring after the PA trigger date or any other data post PA trigger date will 
not be part of the PA.

Blinded review of Information for ARR 
Based on blinded data, the information associated with the ARR endpoint will be monitored to 
determine when the PA can be triggered.  
Fitting a NB model to the aggregate data (i.e., the qualified relapse data of all participants in a 
given study combined) provides an estimate of the overall ARR λ and the dispersion parameter γ. 
For an assumed rate ratio of 0.565 = 0.13/0.23, comparing evobrutinib to teriflunomide, an ARR 
estimate can be obtained for each group, denoted by λ1 for evobrutinib and λ2 for teriflunomide.  
Since the treatment allocation of the participants is unknown, but randomization was done in a 1:1 
ratio, it is assumed that the follow-up times in the 2 groups (j = 1,2, denoting evobrutinib and 
teriflunomide, respectively) are the same, i.e., T·1 = T·2 = Ttotal/2, where Ttotal is the total of the 
follow-up times at the review time. It is further assumed that the sum of the squared follow-up 
times is the same in both groups, i.e., that Σi Ti12 = Σi Ti22 = Σj Σi Tij2/2 = τtotal/2. The information 
for ARR (as per Appendix 5 of the ASCLEPIOS I/II protocol, available as Supplementary Material 
to Hauser 2020) based on blinded data is given by: 
Equation 9.4.4: Information I = [2/(λ1 Ttotal) + 2/(λ2 Ttotal) + 4 γ τtotal/Ttotal2]-1 
where λ1, λ2, and γ are the re-estimated values based on fitting a NB model to the aggregate data, 
and Ttotal and τtotal are as defined above. 
Information for ARR will be monitored in a blinded fashion throughout the study. The first 
criterion of the PA trigger is met when ≥ 32.3 units of information (Section 9.2.1) have been 
collected in the present study (i.e., MS200527_0080) and in the second evobrutinib Phase III study 
(i.e., MS200527_0082), indicating that that the ARR endpoint is powered at ≥ 90% for the 
detection of a 43.5% reduction in ARR at the 1-sided alpha level of 0.025. 
Blinded monitoring of 12-week CDP events  
Pooled CDP events will be monitored in a blinded fashion throughout the studies. The second 
criterion of the PA trigger is met when ≥ 149 pooled 12-week CDP events have been observed, 
indicating that the 12-week CDP endpoint is powered at ≥ 71.5% for the detection of a 34% 
reduction in HR at the 1-sided alpha level of 0.024375. 
9.4.4.3 
Multiplicity  
To control trial-wise and family-wise type I error at the 1-sided 0.025 level in the presence of 
multiple endpoint testing, a graphical approach to sequentially rejective multiple testing will be 
employed (Bretz 2009, Hung 2013, Bretz 2019). The 1-sided null hypotheses in the graph are as 
follows, where “Study 1” denotes the present study, and “Study 2” denotes the second Phase III 
study: 
Primary Endpoint Null Hypotheses: 
H011: rRR1 ≥ 1, where rRR1 denotes qualified relapse rate ratio comparing evobrutinib to 
teriflunomide in Study 1

Secondary Endpoint Null Hypotheses: 
H02: S12e(t) ≤ S12c(t), where S12e(t) denotes the survival function for time to 12-week CDP in the 
experimental (evobrutinib) group based on pooled data, S12c(t) denotes the survival function for 
time to 12-week CDP in the comparator (teriflunomide) group based on pooled data, and the 
variable t denotes time since randomization.  
H03: S24e(t) ≤ S24c(t), where S24e(t) and S24c(t) denotes the survival functions for time to 24-week 
CDP based on pooled data 
H04: S24e(t) ≥ S24c(t), where S24e(t) denotes the survival function for time to 24-week CDI in the 
experimental (evobrutinib) group based on pooled data from participants with baseline EDSS ≥

group based on pooled data from participants with baseline EDSS ≥ 2.0, and the variable t denotes 
time since randomization.  
H05: ΔPF ≤ 0, where ΔPF denotes difference in PROMIS PF score CFB over 96 weeks least-squares 
mean, comparing evobrutinib to teriflunomide, based on pooled data (higher score corresponds to 
improved physical function).  
H06: ΔFatigue ≥ 0, where ΔFatigue denotes difference in PROMIS Fatigue score CFB over 96 weeks 
least-squares mean, comparing evobrutinib to teriflunomide, based on pooled data (higher score 
corresponds to more fatigue).

evobrutinib to teriflunomide in Study 2 
At the PA, the primary efficacy endpoint, ARR, will be tested at the 0.025 (1-sided) level in each 
study. Figure 3 shows the multiple testing procedure involving study-specific endpoints and 
pooled endpoints.

At the PA, the 12-week CDP pooled endpoint will be tested at the 0.025-0.0252 = 0.024375 level, 
1-sided, only if ARR is significant in both studies at the 0.025 level, 1-sided. 
If the 12-week CDP pooled endpoint is significant at the 0.024375 level, 1-sided, the subsequent 
pooled endpoints (24-week CDP, 24-week CDI, PROMIS PF CFB over 96 weeks, PROMIS 
Fatigue CFB over 96 weeks) will be tested in a hierarchical order at 0.024375 level, 1-sided. 
If the primary efficacy endpoint, ARR up to 156 weeks, is significant within a study at the 0.025 
level, 1-sided, the subsequent single-study endpoints (total number of T1 Gd+ lesions based on all 
available MRI scans, number of new/enlarging T2 lesions on the last available MRI scan relative 
to the baseline scan, Week 12 NfL concentration) will be tested in a hierarchical order at the 0.025 
level, 1-sided.

Appendix 2 Study Governance  
Financial Disclosure 
Investigators and Sub-Investigators will provide the Sponsor with sufficient, accurate financial 
information, as requested, for the Sponsor to submit complete and accurate financial certification 
or disclosure statements to the appropriate regulatory authorities. This information is required 
during the study and for 1 year after completion of the study. 
Informed Consent Process 
• The Investigator or his/her representative will explain the nature of the study to the participant 
and answer all questions on the study. 
• Participants must be informed that their participation is voluntary. 
• Participants will be required to sign a statement of informed consent that meets the requirements 
of 21 CFR 50; local regulations; ICH guidelines; Health Insurance Portability and 
Accountability Act (HIPAA) requirements, where applicable; and the IRB/IEC or study center. 
• The medical record must include a statement that written informed consent was obtained before 
the participant was enrolled in the study and the date the written consent was obtained. The 
authorized person obtaining the informed consent must also sign the ICF. 
• If the ICF is updated during their participation in the study, participants must be reconsented to 
the most current, approved version. 
• A copy of the ICF(s) must be provided to the participant. 
• The original signed and dated consent will remain at the Investigator’s site and must be safely 
archived so that it can be retrieved at any time for monitoring, auditing, and inspection purposes. 
• As this study includes optional pharmacogenetic examinations, including collection and storage 
of biological samples, participants may consent to a separate pharmacogenetic analysis, the 
process of which will need to be documented in the participant’s medical records. 
• Participants who are rescreened are required to sign a new ICF. 
• Consenting participant will enter the 4-week screening period to be evaluated for eligibility. 
Please see the SoA (see Section 1.3) for details. Participants must fulfill all entry criteria for 
participation in the study. 
• The screening period may be extended to a total period of 12 weeks after approval by the 
Medical Monitor (see Section 8). The following should be performed: 
• An Eligibility Review Form [ERF] documenting the Investigator’s assessment of each 
screened participant with regard to the protocol’s inclusion and exclusion criteria is to be 
completed by the Investigator. 
• Each participant screened must be registered in the IWRS by the Investigator or the 
Investigator’s research staff at Screening. A screen failure record must be maintained by the 
Investigator, and reasons must be captured in the IWRS.

• It should be stated in the medical record that the participant is participating in this clinical 
study. 
• Eligibility will be evaluated and confirmed by the study eligibility team. Sites will be 
required to submit an eligibility packet to the Medical Monitor (consisting of an eligibility 
checklist and appropriate documentation) for potential eligible participants. 
Data Protection 
• The Sponsor will assign a unique identifier to participants after obtaining their informed 
consent. All participant records or datasets transferred to the Sponsor will contain the identifier 
only; participant names or any identifiable information will not be transferred. 
• The Sponsor must inform participants that their personal study-related data will be used per 
local data protection and privacy laws. The level of disclosure must also be explained to the 
participant and pregnant partners (if applicable), who will be required to give consent for their 
data to be used, as specified in the informed consent. 
• The participant must be informed that his/her medical records may be examined by Clinical 
Quality Assurance auditors or other Sponsor-appointed, authorized personnel, by appropriate 
IRB/IEC members, and by regulatory authority inspectors. All such persons will strictly 
maintain participants’ confidentiality. 
Study Administrative 
This clinical study will be sponsored by Merck Healthcare KGaA Darmstadt, Germany for sites 
outside of the US and Canada and EMD Serono Research & Development Institute, Inc., Billerica, 
MA, US for sites in the US and Canada. 
The study will be conducted at approximately 200 global sites anticipated from approximately 30 
countries (approximately 30 sites in the US). Sites will be a mixture of academic centers and 
outpatient clinics. 
The Coordinating Investigator listed on the title page represents all Investigators for decisions and 
discussions on this study, per ICH GCP. The Coordinating Investigator will provide expert medical 
input and advice on the study design and execution and is responsible for the review and signoff 
of the clinical study report. 
An IDMC, HAC, EAC, and SSC will perform specific study-related activities as detailed in each 
committee’s charter (see Section 8.2.8). 
The study will appear in the following clinical studies registries: ClinicalTrials.gov and EudraCT.

• Consensus ethical principles derived from international guidelines, including the Declaration 
of Helsinki and Council for International Organizations of Medical Sciences (CIOMS) 
International Ethical Guidelines 
• Applicable ICH GCP Guidelines 
• Applicable laws and regulations 
• The Investigator must submit the protocol, protocol amendments (if applicable), ICF, 
Investigator Brochure, and other relevant documents (e.g., advertisements) to an IRB/IEC and 
the IRB/IEC must review and approve them before the study is initiated. 
• Any protocol amendments (i.e., changes to the protocol) will be documented in writing and 
require IRB/IEC approval before implementation of changes, except for changes necessary to 
eliminate an immediate hazard to study participants. When applicable, amendments will be 
submitted to the appropriate Health Authorities. 
• The Investigator will be responsible for the following: 
• Providing written summaries of the status of the study to the IRB/IEC annually or more 
frequently per the IRB’s/IEC’s requirements, policies, and procedures. 
• Notifying the IRB/IEC of SAEs or other significant safety findings, as required by IRB/IEC 
procedures 
• Providing oversight of the study conduct at the site and adherence to requirements of 21 
CFR, ICH guidelines, the IRB/IEC, European regulation 536/2014 for clinical studies (if 
applicable), and all other applicable local regulations 
• The protocol and any applicable documentation will be submitted or notified to the Health 
Authorities in accordance with all local and national regulations for each site. 
Emergency Medical Support 
• The Sponsor or designee will provide Emergency Medical Support cards to participants for use 
during the study. These provide the means for participants to identify themselves as 
participating in a clinical study. Also, these give health care providers access to any information 
about this participation that may be needed to determine the course of medical treatment for the 
participant. The information on the Emergency Medical Support card may include the process 
for emergency unblinding (if applicable). 
• The first point of contact for all emergencies will be the clinical study Investigator caring for 
the participant. Consequently, the Investigator agrees to provide his or her emergency contact 
information on the card. If the Investigator is available when an event occurs, they will answer 
any questions. Any subsequent action (e.g., unblinding) will follow the standard process 
established for Investigators. 
When the Investigator is not available, the Sponsor provides the appropriate means to contact a 
Sponsor (or designee) physician. This includes provision of a 24-hour contact number at a call 
center, whereby the health care providers will be given access to the appropriate Sponsor (or 
designee) physician to assist with the medical emergency and to provide support for the potential 
unblinding of the participant concerned.

Data Quality Assurance 
• All participant study data will be recorded on printed or electronic CRFs or transmitted to the 
Sponsor or designee electronically (e.g., laboratory data). The Investigator is responsible for 
verifying that data entries are complete, accurate, legible, and timely by physically or 
electronically signing the CRF. Details for managing CRFs are in the Pharmacy Manual. 
• For PRO data (e.g., QoL and pain assessments), ePRO will be used. 
• The Investigator must maintain accurate documentation (source data) that supports the 
information in the CRF. 
• The Investigator must permit study-related monitoring, quality assurance audits, IRB/IEC 
review, and regulatory agency inspections and provide direct access to the study file and source 
data. 
• QTLs will be predefined and documented in the applicable project management database to 
help support the identification of systematic issues that could potentially impact participant 
safety and/or reliability of study results. These predefined parameters will be monitored during 
the study and important deviations from the QTL thresholds and remedial actions taken will be 
summarized in the clinical study report. 
• Monitoring details describing strategy (e.g., risk-based initiatives in operations and quality such 
as Risk Management and Mitigation Strategies and Analytical Risk-Based Monitoring), 
methods, responsibilities, and requirements, including handling of noncompliance issues and 
monitoring techniques (central, remote, or on-site monitoring) are in the Monitoring Plan. 
• The Sponsor or designee is responsible for data management of this study, including quality 
checking of the data and maintaining a validated database. Database lock will occur once quality 
control and quality assurance procedures have been completed. PDF files of the CRFs will be 
provided to the Investigators at study completion. 
• Study monitors will perform ongoing source data verification to confirm that data in the CRF 
are accurate, complete, and verifiable; that the safety and rights of participants are being 
protected; and that the study is being conducted per the currently approved protocol and any 
other study agreements, ICH GCP, and all applicable regulatory requirements. 
• Records and documents, including signed ICFs, pertaining to the conduct of this study must be 
retained by the Investigator for 15 years after study completion, unless local regulations, 
institutional policies, or the Sponsor requires a longer retention. No records may be destroyed 
during the retention period without the Sponsor’s written approval. No records may be 
transferred to another location or party without the Sponsor’s written notification. 
Source Documents 
• Source documents provide evidence for the existence of the participant and substantiate the 
integrity of the data collected. 
• The Investigator must keep a paper or electronic file (medical file and original medical records) 
at the site for each study participant. The file must identify each participant, contain the 
following demographic and medical information for the participant, and should be as complete 
as possible: 
Global Version ID: 78691_4679269_6096058

• Participant’s full name, date of birth, sex, height, and weight 
• Medical history and concomitant diseases 
• Prior and concomitant therapies (including changes during the study) 
• Study identifier (i.e., the Sponsor’s study number) and participant’s study number. 
• Dates of entry into the study (i.e., signature date on the informed consent) and each visit to 
the site 
• Any medical examinations and clinical findings predefined in the protocol 
• All AEs 
• Date that the participant left the study, including any reason for early withdrawal from the 
study or study intervention, if applicable. 
• All source data must be filed (e.g., CT or MRI scan images, ECG recordings, and laboratory 
results). Each document must have the participant number and the procedure date; ideally, 
printed by the instrument used for the procedure. As necessary, medical evaluation of these 
records should be performed, documented, signed, and dated by the Investigator.  
• Data recorded on printed or electronic CRFs that are transcribed from source documents must 
be consistent with the source documents or the discrepancies must be explained. The 
Investigator may need to request previous medical records or transfer records, depending on the 
study. Also, current medical records must be available. 
• The study monitors will use printouts of electronic files for source data verification. These 
printouts must be signed and dated by the Investigator and kept in the study file. 
• Source documents are stored at the site for the longest possible time permitted by the applicable 
regulations, and/or as per ICH GCP guidelines, whichever is longer. The Investigator ensures 
that no destruction of medical records is performed without the Sponsor’s written approval. 
• Definition of what constitutes source data is found in the eCRF guidelines. 
Study and Site Closure 
• The Sponsor reserves the right to close the study site or terminate the study at any time and for 
any reason, including but not limited to new or emerging safety information that negatively 
affects the benefit/risk assessment of the clinical study. Study sites will be closed upon study 
completion. A study site is considered closed when all required documents and study supplies 
have been collected and a site closure visit has been completed. 
• The Investigator may initiate site closure at any time, provided there is reasonable cause and 
sufficient notice is given in advance of the intended termination. 
• Reasons for the early closure of a study site by the Sponsor or Investigator may include: 
• Failure of the Investigator to comply with the protocol, the requirements of the IRB/IEC or 
local health authorities, the Sponsor’s procedures, or GCP guidelines 
• Inadequate recruitment of participants by the Investigator 
• Discontinuation of further development of the Sponsor’s compound

• If the study is prematurely terminated or suspended, the Sponsor will promptly inform the 
Investigators, the IECs/IRBs, the regulatory authorities, and any contract research 
organization(s) used in the study of the reason for termination or suspension, as specified by 
the applicable regulatory requirements. The Investigator will promptly inform the participants 
and assure appropriate participant therapy and/or follow-up.

Appendix 3 Contraception  
Definitions: 
Woman of Childbearing Potential (WOCBP) 
A woman is considered fertile following menarche and until becoming postmenopausal unless 
permanently sterile, as specified below. 
If fertility is unclear (e.g., amenorrhea in adolescents or athletes) and a menstrual cycle cannot be 
confirmed before the first dose of study intervention, consider additional evaluation. 
A WOCBP is not: 
1. Premenarchal 
2. A premenopausal female with 1 of the following: 
• Documented hysterectomy 
• Documented bilateral salpingectomy 
• Documented bilateral oophorectomy 
Documentation can come from the site personnel’s review of the female’s medical 
records, medical examination, or medical history interview. 
For a female with permanent infertility due to an alternate medical cause other than the 
above, (e.g., Müllerian agenesis, androgen insensitivity), Investigator discretion applies 
to determine study entry. 
3. A postmenopausal female 
• A postmenopausal state is defined as no menses for 12 months without an alternative medical 
cause. 
a. A high follicle-stimulating hormone (FSH) level in the postmenopausal 
range may be used to confirm a postmenopausal state in a female not using 
hormonal contraception or hormonal replacement therapy (HRT). However, 
in the absence of 12 months of amenorrhea, more than 1 FSH measurement 
is required in the postmenopausal range. 
• A female on HRT and whose menopausal status is in doubt will be required to use one of 
the nonestrogen hormonal highly effective contraception methods if she wishes to continue 
her HRT during the study. Otherwise, she must discontinue HRT to allow confirmation of 
postmenopausal status before study enrollment.

Contraception Guidance: 
CONTRACEPTIVES ALLOWED DURING THE STUDY INCLUDE: 
Highly Effective Methods That Have Low User Dependency 
• 
Implantable progestogen-only hormone contraception associated with inhibition of ovulationa 
• 
Intrauterine device (IUD) 
• 
Intrauterine hormone-releasing system (IUS)a 
• 
Bilateral tubal occlusion 
• 
Vasectomized partnerb: a highly effective contraceptive method provided that the partner is the sole sexual 
partner of a WOCBP and the absence of sperm has been confirmed. Otherwise, use an additional highly 
effective method of contraception. The spermatogenesis cycle is approximately 90 days. 
Highly Effective Methods That Are User Dependent  
• 
Combined (estrogen- and progestogen-containing) hormonal contraception associated with inhibition of 
ovulationa 
o 
Oral 
o 
Intravaginal 
o 
Transdermal 
o 
Injectable 
• 
Progestogen-only hormone contraception associated with inhibition of ovulationa 
o 
Oral 
o 
Injectable 
• 
Sexual abstinence: a highly effective method only if defined as refraining from intercourse during the entire 
period of risk associated with the study intervention. The reliability of sexual abstinence needs to be evaluated 
in relation to the duration of the study. Abstinence is only acceptable as a contraceptive method for study 
purposes if it is in line with the preferred and usual lifestyle of the participant as evaluated by the Investigator. 
Barrier Methods  
• 
Male or female condom with or without spermicide 
• 
Cap, diaphragm, or sponge with spermicide 
a 
Evobrutinib has been characterized as both an inducer and a time-dependent inhibitor of CYP3A4/5 in vitro, 
an enzyme involved in the metabolism of estrogen and progestin. Although it is a low risk, it is possible that 
coadministration with evobrutinib results in increased metabolism of estrogen, progestin, and other hormones used 
for contraception, increasing the likelihood that hormonal contraception methods, marked above with a, might fail. 
However, all participants that are WOCBP are required to use a barrier method as backup (see Inclusion Criterion 6) 
in part to mitigate this potential risk. 
Teriflunomide may increase the systemic exposures of ethinylestradiol and levonorgestrel. Consideration should

If a WOCBP participant is using a highly effective method other than sexual abstinence or vasectomized 
partner, AND ALSO has a vasectomized partner, the vasectomized partner will be considered the “barrier method” 
for study purposes. 
Notes: 
Contraceptive use by men or women is consistent with local regulations on the use of contraceptive methods for 
clinical study participants. 
Highly effective methods are those with a failure rate of < 1% per year when used consistently and correctly. Typical 
use failure rates differ from those when used consistently and correctly. 
If locally required, in accordance with Clinical Trial Facilitation Group (CTFG) guidelines, acceptable contraceptive 
methods are limited to those which inhibit ovulation as the primary mode of action. 
Periodic abstinence (calendar, symptothermal, postovulation methods), withdrawal (coitus interruptus), spermicides 
only, and lactational amenorrhoea method (LAM) are not acceptable methods of contraception for this study. Male 
condom and female condom cannot be used together (due to risk of failure with friction).

Appendix 4 
Adverse Events: Definitions and Procedures for Recording, 
Evaluating, Follow-up, and Reporting  
Definitions 
Adverse Event 
An AE is any untoward medical occurrence in a participant administered a pharmaceutical product, 
regardless of causal relationship with this treatment. Therefore, an AE can be any unfavorable and 
unintended sign (including an abnormal laboratory finding), symptom, or disease temporally 
associated with the use of a medicinal product, regardless if it is considered related to the medicinal 
product. 
For surgical or diagnostic procedures, the condition/illness leading to such a procedure is 
considered as the AE rather than the procedure itself. 
The Investigator is required to grade the severity or toxicity of each AE. 
Investigators will reference the NCI-CTCAE, version 5.0 (publication date: 27 November 2017), 
a descriptive terminology that can be used for AE reporting. 
A general grading (severity/intensity; hereafter referred to as severity) scale is provided at the 
beginning of the above referenced document, and specific event grades are also provided. 
If the severity for an AE is not specifically graded by NCI-CTCAE, the Investigator is to use the 
general NCI-CTCAE definitions of Grade 1 through Grade 5, using his or her best medical 
judgment. 
The 5 general grades are: 
Grade 1 or Mild 
Grade 2 or Moderate 
Grade 3 or Severe  
Grade 4 or Life-threatening  
Grade 5 or Death  
Any clinical AE with severity of Grade 4 or 5 must also be reported as an SAE. However, a 
laboratory abnormality of Grade 4, such as anemia or neutropenia, is considered serious only if the 
condition meets one of the serious criteria specified below. 
If death occurs, the primary cause of death or event leading to death should be recorded and 
reported as an SAE. “Fatal” will be recorded as the outcome of this specific event and death will 
not be recorded as separate event. Only, if no cause of death can be reported (e.g., sudden death, 
unexplained death), the death per se might then be reported as an SAE.

Investigators must also systematically assess the causal relationship of AEs to study intervention 
(including any other nonstudy interventions, radiation therapy, etc.) using the following 
definitions. Decisive factors for the assessment of causal relationship of an AE to the study 
interventions (evobrutinib and teriflunomide) include, but may not be limited to, temporal 
relationship between the AE and the study interventions, known side effects of study interventions, 
medical history, concomitant medication, course of the underlying disease, and study procedures. 
Unrelated: 
Not reasonably related to the study intervention. AE could not medically 
(pharmacologically/clinically) be attributed to the study intervention under study in 
this clinical study protocol. A reasonable alternative explanation must be available. 
Related: 
Reasonably 
related 
to 
the 
study 
intervention. 
AE 
could 
medically 
(pharmacologically/clinically) be attributed to the study intervention under study in 
this clinical study protocol.  
Abnormal Laboratory Findings and Other Abnormal Investigational Findings 
Abnormal laboratory findings and other abnormal investigational findings (e.g., on an ECG trace) 
should not be reported as AEs unless they are associated with clinical signs and symptoms, lead to 
study intervention discontinuation, or are considered otherwise medically important by the 
Investigator. If a laboratory abnormality fulfills these criteria, the identified medical condition 
(e.g., anemia or increased ALT) must be reported as the AE rather than the abnormal value itself. 
Serious Adverse Events 
An SAE is any untoward medical occurrence that at any dose: 
• Results in death 
• Is life-threatening. Life-threatening refers to an event in which the participant is at risk of death 
at the time of the event, not an event that hypothetically might have caused death if it was more 
severe. 
• Requires inpatient hospitalization or prolongs an existing hospitalization 
• Results in persistent or significant disability or incapacity 
• Is a congenital anomaly or birth defect 
• Is otherwise considered to be medically important. Important medical events that may not result 
in death, be life-threatening, or require hospitalization may be considered as SAEs when, based 
upon appropriate medical judgment, they may jeopardize the participant or may require medical 
or surgical intervention to prevent one of the outcomes listed above. Examples of such events 
include allergic bronchospasm requiring intensive treatment in an emergency room or at home, 
blood dyscrasias or convulsions that do not result in inpatient hospitalization, or the 
development of drug dependency or drug abuse. 
For the purposes of reporting, any suspected transmission of an infectious agent via a study 
intervention is also considered an SAE, as specified below for reporting SAEs and AESIs.

178/262 
 
 
Events that Do Not Meet the Definition of an SAE 
Elective hospitalizations to administer, or to simplify study intervention or procedures (e.g., an 
overnight stay to facilitate intravenous therapy) are not considered SAEs. However, all events 
leading to unplanned hospitalizations or unplanned prolongation of an elective hospitalization (i.e., 
undesirable effects of any administered treatment) must be documented and reported as SAEs. 
Events Not to Be Considered as AEs/SAEs 
Medical conditions present at the initial study visit that do not worsen in severity or frequency 
during the study are defined as Baseline Medical Conditions, and are not to be considered AEs. 
Worsening of the underlying disease is not routinely to be considered an AE or SAE, but is rather 
an efficacy endpoint, unless deemed to be causally related to the IMP. However, if significant 
adverse signs or symptoms occur in association with complications or a prolonging of a 
hospitalization originally due to relapse or disease progression, then these specific complications 
or hospital prolongation events should be recorded as AEs. 
Adverse Events of Special Interest 
Adverse events of special interest are liver AEs (possible drug-induced, non-infectious, 
non-alcoholic, and immune-mediated), infections (serious and opportunistic infections), lipase and 
amylase elevation, and seizure, as described in Section 6.9. 
Other Adverse Events to be Reported Following a Specialized Procedure  
The following procedures should be followed for reporting overdoses (refer to eCRF guidelines 
for further details): 
• Overdoses without an AE should be reported using the paper SAE form only, stating if the 
overdose was accidental or intentional. 
• Overdoses associated with a nonserious AE should be recorded on the AE eCRF. 
• Overdoses associated with an SAE should be recorded on the AE eCRF and the SAE reporting 
procedure outlined below should be followed. 
Recording and Follow-Up of AE and/or SAE 
It is important that each AE report include a description of the event, its duration (onset and 
resolution dates and also onset and resolution times, when it is important to assess the time of AE 
onset relative to the recorded study intervention administration time), its severity, its causal 
relationship with the study intervention, any other potential causal factors, any treatment given or 
other action taken, including dose modification or discontinuation of the study intervention, and 
its outcome. In addition, serious cases should be identified and the appropriate seriousness criteria 
documented.  
Specific guidance is in the CRF Completion and Monitoring Conventions provided by the Sponsor.

Reporting Serious Adverse Events and Adverse Events of Special Interest 
Serious Adverse Events 
In the event of any new SAE occurring during the reporting period, the Investigator must 
immediately inform the Sponsor or its designee using the electronic SAE report form in the 
Electronic Data Capture (EDC) system. The site will enter into the electronic system the SAE data 
within 
24 hours 
after 
becoming 
aware 
of 
the 
event. 
It 
is 
expected 
that 
the 
investigator/sub-investigator signs off this data in the system and any relevant associated data (e.g., 
additional laboratory tests, medical records, diagnostic reports, histopathological examinations, or 
consultation with other health care professionals) will be entered as soon as it becomes available. 
Reporting of SAEs using a paper report form is required as a back-up method only for an EDC 
system failure. Names, addresses, and telephone and fax numbers will be included on the paper 
form. All information from the paper form must be transcribed into the electronic form as soon as 
the system becomes available. 
In exceptional circumstances, an SAE (or follow-up information) may be reported by telephone; 
in these cases, an electronic SAE report form must be completed immediately thereafter. 
Relevant pages from the CRF may be provided in parallel (e.g., medical history, concomitant 
drugs). Additional documents may be provided by the Investigator, if available (e.g., laboratory 
results, hospital report, autopsy report).  
The Investigator must respond to any request for follow-up information (e.g., additional 
information, outcome, final evaluation, other records where needed) or to any question the 
Sponsor/designee may have on the AE within the same timelines as those noted above for initial 
reports. This is necessary to ensure prompt assessment of the event by the Sponsor or designee and 
(as applicable) to allow the Sponsor to meet strict regulatory timelines associated with expedited 
safety reporting obligations. 
Requests for follow-up will usually be made via the study monitor, although in exceptional 
circumstances the global patient safety department may contact the Investigator directly to obtain 
further information or to discuss the event. 
Adverse Events of Special Interest 
For a non-serious AESI, the site will complete the specific AESI report form and notify the 
Sponsor immediately (within 24 hours), using the same process for reporting SAEs, as specified 
above. 
For a serious AESI, the site will complete an SAE report form, using the SAE reporting process, 
specified above. 
Suspected Unexpected Serious Adverse Reactions (SUSARs) 
Individual Case Safety Reports will be prepared for SUSARs according to local regulatory 
requirements and Sponsor policy and forwarded to Investigators within 15 days.

SUSAR or other specific safety information (e.g., Emerging Safety Issue Report, summary or 
listing of SAEs/SUSARs) from the Sponsor will review the safety reports and confirm completion 
of this review. This information will be filed it in the Investigator’s Site File, and the IRB/IEC will 
be notified, if appropriate, according to applicable local laws/regulations and site SOPs.

Pharmacogenetics  
Use/Analysis of DNA 
• Genetic variation may impact a participant’s response to therapy, susceptibility to, and 
severity and progression of disease. Variable response to therapy may be due to genetic 
determinants that impact study intervention absorption, distribution, metabolism, and 
excretion; mechanism of action of the study intervention; disease etiology; and/or molecular 
subtype of the disease being treated. 
• DNA samples may be used for research related to pharmacokinetics, safety endpoints, drug 
response, and treatment efficacy of evobrutinib or MS and related diseases. They may also 
be used to develop tests or assays, including diagnostic tests related to pharmacokinetics, 
safety endpoints, drug response, and treatment efficacy of evobrutinib and MS. 
Pharmacogenetic research may consist of the analysis of one or more candidate genes or the 
analysis of genetic markers throughout the genome or analysis of the entire genome (as 
appropriate). 
• The results of pharmacogenetic analyses may be reported in the CSR or in a separate study 
summary. 
• Details on processes for collection and shipment of these samples can be found in the 
Laboratory Manual. The Sponsor will store the DNA samples in a secure storage space with 
adequate measures to protect confidentiality. 
• Retention time and possible analysis of DNA sample after the study ends are specified in the 
respective ICF.

Appendix 7 
Guidance for Diagnosis of PML  
The safety monitoring algorithm presented in Figure 4 will be implemented in this study. 
Comprehensive neurological assessments will be performed every 12 weeks at the regular study 
visits. Additionally, telephone interviews will be conducted to assess for new or worsening 
neurological symptoms and a neurological evaluation will be conducted if clinically indicated. 
This neurological exam will include calculation of an EDSS score at the scheduled 12-week visit 
or in the event of new/worsening symptoms. This exam requires that FSS also be determined. The 
examination to calculate the FSS includes cognitive, visual, and motor assessments, as well as 
assessments of other neurological systems. These neurological systems are often affected by PML, 
and by MS as well. 
Should a non-MS etiology, such as PML, be considered as a differential etiology for any change 
in the clinical picture (neurological symptoms and/or exam), further assessments should be done. 
The evaluation of PML may include a brain MRI scan and CSF analysis per the proposed treatment 
algorithm (Figure 4). 
Action Steps if PML is suspected: 
If the clinical presentation is suggestive of PML, further investigations should include brain MRI 
evaluation as soon as possible. If MRI evaluation reveals lesions suspicious for PML a lumbar 
puncture with evaluation of the CSF for the detection of JCV DNA should be undertaken 
(performed by central laboratory). A diagnosis of PML can potentially be made by evaluating 
clinical and MRI findings plus the identification of JCV in the CSF.  
MRI Assessments 
Although there are no pathognomonic findings that differentiate PML from MS, a brain MRI scan 
that includes fluid-attenuated inversion recovery (FLAIR) and T2-weighted and T1-weighted 
sequences, with and without Gd, should be performed to assess patients with neurological changes 
suggestive of PML. 
CSF Assessment 
• The detection of JCV DNA in the CSF of a participant with clinical and MRI features suggestive 
of PML establishes the diagnosis of PML. 
• If JCV DNA is not detected in CSF and if clinical suspicion of PML remains high, a repeat 
lumbar puncture should be performed. 
• If diagnosis remains uncertain and suspicion of PML remains high, a brain biopsy may be 
considered to establish a definitive diagnosis. 
• CSF will be analyzed centrally.

Appendix 8 
Procedure for Accelerated Elimination of Teriflunomide  
Teriflunomide is eliminated slowly from the plasma based on the teriflunomide SmPC and 
teriflunomide USPI. Without an accelerated elimination procedure (AEP), it takes on average 
8 months to reach plasma concentrations < 0.02 mg/L, although because of individual variations 
in drug clearance it may take as long as 2 years. An AEP could be used at any time after 
discontinuation of teriflunomide. Elimination can be accelerated by either of the following 
procedures, or as per local standard of care: 
• Administration of cholestyramine 8 g every 8 hours 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 powder every 12 hours 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. At the end of 11 days, 
both regimens successfully accelerated teriflunomide elimination, leading to more than 98% 
decrease in teriflunomide plasma concentrations. Use of the AEP may potentially result in return 
of disease activity if the participant had been responding to treatment with teriflunomide. 
In accordance with the teriflunomide prescribing information, it is recommended to confirm a 
teriflunomide level of < 0.02 mg/L after the AEP if the AEP is being done for pregnancy-related 
considerations. All participants previously treated with teriflunomide, or with an unknown 
exposure status during the DBTP and DBE periods entering the OLE, should undergo mandatory 
AEP (all genders) upon completion of the DBE period. The Investigator should dispense 
cholestyramine or activated charcoal and to instruct participant about proper intake. The blood 
concentration of teriflunomide has to be verified upon completion of the AEP via blood sample 
collection between Day 12 to Day 30 at the central laboratory. The Investigator will remain blinded 
to the teriflunomide levels. Please refer to the study-specific central laboratory manual for detailed 
information on the teriflunomide blood level testing. If the AEP is being done for any other safety 
reason (e.g., elevated LFTs), a level can be obtained after the AEP, but is not required.

Appendix 9 
Teriflunomide Drug-Drug Interactions  
Teriflunomide has the potential for drug interactions and due to the blinded treatment assignment, 
these should be considered when treating participants. The following are the potential drug 
interactions as defined in the teriflunomide USPI (teriflunomide USPI). 
• DRUG INTERACTIONS 
• Effect of AUBAGIO on CYP2C8 Substrates 
• Teriflunomide is an inhibitor of CYP2C8 in vivo. In patients taking AUBAGIO, exposure of 
drugs metabolized by CYP2C8 (e.g., paclitaxel, pioglitazone, repaglinide, rosiglitazone) may 
be increased. Monitor these patients and adjust the dose of the concomitant drug(s) 
metabolized by CYP2C8 as required. 
• Effect of AUBAGIO on Warfarin 
• Coadministration of AUBAGIO with warfarin requires close monitoring of the INR because 
AUBAGIO may decrease peak INR by approximately 25%. 
• Effect of AUBAGIO on Oral Contraceptives 
• AUBAGIO may increase the systemic exposures of ethinylestradiol and levonorgestrel. 
Consideration should be given to the type or dose of contraceptives used in combination with 
AUBAGIO. 
• Effect of AUBAGIO on CYP1A2 Substrates 
• Teriflunomide may be a weak inducer of CYP1A2 in vivo. In patients taking AUBAGIO, 
exposure of drugs metabolized by CYP1A2 (e.g., alosetron, duloxetine, theophylline, 
tizanidine) may be reduced. Monitor these patients and adjust the dose of the concomitant 
drug(s) metabolized by CYP1A2 as required. 
• Effect of AUBAGIO on Organic Anion Transporter 3 (OAT3) Substrates 
• Teriflunomide inhibits the activity of OAT3 in vivo. In patients taking AUBAGIO, exposure 
of drugs which are OAT3 substrates (e.g., cefaclor, cimetidine, ciprofloxacin, penicillin G, 
ketoprofen, furosemide, methotrexate, zidovudine) may be increased. Monitor these patients 
and adjust the dose of the concomitant drug(s) which are OAT3 substrates as required. 
• Effect of AUBAGIO on BCRP and Organic Anion Transporting Polypeptide B1 and B3 
(OATP1B1/1B3) Substrates 
• Teriflunomide inhibits the activity of BCRP and OATP1B1/1B3 in vivo. For a patient taking 
AUBAGIO, the dose of rosuvastatin should not exceed 10 mg once daily. For other substrates 
of BCRP (e.g., mitoxantrone) and drugs in the OATP family (e.g., methotrexate, rifampin), 
especially HMG-Co reductase inhibitors (e.g., atorvastatin, nateglinide, pravastatin, 
repaglinide, and simvastatin), consider reducing the dose of these drugs and monitor patients 
closely for signs and symptoms of increased exposures to the drugs while patients are taking 
AUBAGIO. 
DRUG INTERACTION STUDIES 
• Teriflunomide is not metabolized by Cytochrome P450 or flavin monoamine oxidase enzymes.

• The potential effect of AUBAGIO on other drugs: 
• CYP2C8 substrates 
o There was an increase in mean repaglinide Cmax and AUC (1.7- and 2.4-fold, 
respectively) following repeated doses of teriflunomide and a single dose of 0.25 mg 
repaglinide, suggesting that teriflunomide is an inhibitor of CYP2C8 in vivo. The 
magnitude of interaction could be higher at the recommended repaglinide dose. 
• CYP1A2 substrates 
o Repeated doses of teriflunomide decreased mean Cmax and AUC of caffeine by 18% 
and 55%, respectively, suggesting that teriflunomide may be a weak inducer of 
CYP1A2 in vivo. 
• OAT3 substrates 
o There was an increase in mean cefaclor Cmax and AUC (1.43- and 1.54-fold, 
respectively), following repeated doses of teriflunomide, suggesting that teriflunomide 
is an inhibitor of organic anion transporter 3 (OAT3) in vivo. 
• BCRP and OATP1B1/1B3 substrates 
o There was an increase in mean rosuvastatin Cmax and AUC (2.65- and 2.51-fold, 
respectively) following repeated doses of teriflunomide, suggesting that teriflunomide 
is an inhibitor of BCRP transporter and organic anion transporting polypeptide 1B1 and 
1B3 (OATP1B1/1B3). 
• Oral contraceptives 
o There was an increase in mean ethinylestradiol Cmax and AUC0-24 (1.58- and 1.54-fold, 
respectively) and levonorgestrel Cmax and AUC0-24 (1.33- and 1.41-fold, respectively) 
following repeated doses of teriflunomide. 
• Teriflunomide did not affect the pharmacokinetics of bupropion (a CYP2B6 substrate), 
midazolam (a CYP3A4 substrate), S-warfarin (a CYP2C9 substrate), omeprazole (a CYP2C19 
substrate), and metoprolol (a CYP2D6 substrate). 
• The potential effect of other drugs on AUBAGIO 
• Potent CYP and transporter inducers: Rifampin did not affect the pharmacokinetics of 
teriflunomide.

Structured Interview at Telephone Contact  
The primary purpose of this interview is to identify any new or worsening neurological symptoms 
that warrant evaluation at an unscheduled visit. Structured interviews should be performed by 
study personnel between clinic visits – see also Section 1.3 and Section 8. 
Telephone contacts between D1 and W44 are not expected to occur every 4 weeks, since 
participants are scheduled to be on site at least every 4 weeks. However, if a participant is utilizing 
the home visit option, telephone contacts should occur as indicated in the SoA. Telephone contacts 
between W44 and W156 should occur every 4 weeks if a clinic visit is not scheduled. 
If the participant is a woman of childbearing potential, please remember to confirm completion of 
home pregnancy testing and discuss results. 
Please ask the following questions and record participant’s answers during the Structured 
Interview: 
# 
Question: 
No 
Yes 
1 
Since your last visit or structured interview, have you had any new or 
worsening medical problems (such as sudden changes in your thinking, 
alterations in your behavior, visual disturbances, extremity weakness, 
limb coordination problems, or gait abnormalities) that have persisted over 
several days? 
 
 
2 
Since your last visit or structured interview, have you taken any new 
medicines or had any changes in your medicines? 
 
 
3 
Since your last visit or structured interview, have you had any notable 
medical events (e.g., new or changed signs or symptoms, procedures, 
injuries, or laboratory tests/imaging outside of the study) 
 
 
If the participant answered YES to any question, the interviewer should contact the Treating 
Investigator and review the participant’s answers. The Treating Investigator should determine if 
an unscheduled visit is required.

reporting of HR = 0.66 (Hauser et al 
2020), comparing hazard of first 
12-week CDP event between 
ofatumumab and teriflunomide, is 
used to revise the assumption of the 
12-week CDP treatment effect. 
• 
To clarify action taken previously 
(when IA for BSSR was conducted 
in August 2021) to ensure adequate 
power for 12-week CDP. 
9.2.3 Sample Size 
Considerations due to the 
Currently Escalating Crisis in 
Eastern Europe

evobrutinib)" to "(excluding 
evobrutinib)". 
• 
Removal of prohibited medicines 
specific for the OLE Period. 
• 
Correction of typographical error. 
• 
For consistency with the removal of 
the OLE Period. 
8.1.1.3 Confirmed Disability 
Improvement 
Addition of definitions for CDI. 
For clarification. 
8.3.4 Regulatory Reporting 
Requirements for Serious 
Adverse Events 
Text on SUSAR reporting was 
updated in line with the latest protocol 
template. 
To comply with changes to the protocol 
template, which includes a clarified text 
on the SUSAR reporting process. 
8.8 Biomarkers 
Approximate blood volume planned to 
be collected during the study was 
updated. 
To reflect the increased duration 
including additional visits and 
associated sampling. 
8.8.2.1 Neurofilament Light 
Chain 
Added detailed information on NfL as 
biomarker of disease, corresponding 
to the inclusion of NfL as a new 
secondary endpoint. 
NfL has emerged as a potential 
biomarker for disease activity and 
treatment monitoring of patients with 
MS. Additional information added to 
support the inclusion of NfL as 
secondary endpoint. 
9.1.2 Statistical Hypotheses 
Related to Secondary 
Objectives 
Added description of hypotheses 
regarding secondary endpoints Time 
to 24-Week CDI and Week 12 NfL 
concentration.  
To pre-specify hypotheses regarding all 
secondary endpoints in protocol. 
9.2.1 Sample Size for Primary 
Endpoint: ARR 
Added equation 9.2.1 for the 
information for ARR provided by a 
given sample size, followed for a 
common follow-up time.  
The target information required to 
adequately power the ARR endpoint 
should be pre-specified, as the primary 
analysis will be triggered by achieving 
the target information in both studies, 
plus target CDP events pooled.  
9.2.2 Sample Size for 
Secondary Endpoint: 12-week 
CDP 
• 
Revised the assumption on 
treatment effect on 12-week CDP 
endpoint from HR = 0.7 to 
HR = 0.66. 
• 
Summarized the outcome of the 
optional IA for BSSR. 
• 
Evobrutinib is considered to have 
efficacy similar to that of anti-CD20 
therapies. Therefore, recent 
reporting of HR = 0.66 (Hauser et al 
2020), comparing hazard of first 
12-week CDP event between 
ofatumumab and teriflunomide, is 
used to revise the assumption of the 
12-week CDP treatment effect. 
• 
To clarify action taken previously 
(when IA for BSSR was conducted 
in August 2021) to ensure adequate 
power for 12-week CDP. 
9.2.3 Sample Size 
Considerations due to the 
Currently Escalating Crisis in 
Eastern Europe 
Added description of re-opening of 
enrollment driven by loss of data due 
to the currently escalating crisis in 
Eastern Europe. 
To ensure primary and important 
secondary endpoints are adequately 
powered despite loss of data from 
participants at sites in Ukraine, Russian 
Federation, and Belarus. 
9.3 Population for Analyses 
• 
Inclusion of modified analysis sets 
(mFAS and mSAF) 
• 
Removal of analysis set specific for 
the OLE Period. 
• 
To address potential lack of data 
robustness for data from participants 
and sites in Ukraine, Russian 
Federation, and Belarus. 
• 
For consistency with the removal of 
the OLE Period.

9.4.4.2 Primary Analysis 
• 
Described trigger for primary 
analysis based on achieving 
sufficient information for ARR in 
each study and sufficient 12-week 
CDP events from pooled studies. 
• 
Added Equation 9.4.4 for blinded 
monitoring of information for ARR 
provided by a study. 
• 
For consistency with change to 
study from fixed to variable 
treatment duration, where primary

Description of Change 
Brief Rationale 
9.4.4.3 Multiplicity 
Updated multiple testing strategy to 
incorporate addition of 2 secondary 
endpoints, minor change to testing 
order (CDI endpoint tested prior to 
PRO endpoints), and minor correction 
to alpha level for pooled tests. 
Multiplicity graph updated to depict the 
strategy update. 
To ensure that the multiple testing 
strategy provides a more complete 
picture of treatment effect on EDSS and 
NfL levels. Alpha level at which pooled 
tests are to be conducted was corrected 
from 0.025 to 0.02475 based on 
Bretz 2019.

EQ-5D-5L
The EQ-5D questionnaire comprises 5 questions (items) relating to current problems in the 
dimensions mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. 
Responses in each dimension are divided into 5 ordinal levels coded: (1) no problems, (2) slight 
problems, (3) moderate problems, (4) severe problems, (5) extreme problems. This part, called the 
EQ-5D descriptive system, provides a 5-dimensional description of health status. 
A unique health state is defined by combining one level from each of the 5 dimensions. A total of 
3125 possible health states is defined in this way. Each state is referred to in terms of a 5-digits 
code. For example, state 11111 indicates no problems on any of the 5 dimensions, while state 
12345 indicates no problems with mobility, slight problems with self-care, moderate problems 
with doing usual activities, severe pain or discomfort, and extreme anxiety or depression.
The EQ-5D-5L descriptive system is followed by a VAS (EQ VAS), similar to a thermometer, 
ranging from 0 (worst imaginable health state) to 100 (best imaginable health state). The EQ VAS 
records the respondent’s self-rated valuation of health state, i.e. a value which is based on the 
respondent's preferences (EQ VAS score).
Based on the EQ-5D-5L, the numeric EQ-5D-5L index can be derived, using validated translations 
provided by EuroQoL presented in the following XLS file. The EQ-5D-5L index is frequently 
used in economic evaluations: it represents societal preference values for the full set of EQ-5D-5L 
health states with the best state (perfect health) and “death” being assigned values of 1 and 0, 
respectively.
The United Kingdom value set of this questionnaire will be used for all participants regardless of 
their country.
