 Number of headache days of any severity 
 Number of days with use of any acute headache 
medications 
 Number of subjects discontinuing concomitant 
preventive migraine medications during the treatment 
period 
 Number of days with nausea or vomiting 
 Number of days with photophobia or phonophobia 
 HIT-6 (for subjects with CM only)

 MSQOL 
 EQ-5D-5L 
 PGIC 
 PHQ-2 and PHQ-9 
 WPAI 
Statistical Methods: 
[Safety analysis] 
Safety endpoint data will be summarized overall and by 
treatment group in the safety analysis set. 
[Rationale for Target Sample Size] 
Sample size was not calculated by any statistical method. 
To fully evaluate the long-term safety of TEV-48125 in 
Japanese patients, it is necessary to collect data from 100 
Japanese patients who have completed a 1-year treatment 
with the drug at the same doses and regimens as those in the 
phase 2b/3 trials (Trials 406-102-00001 and 406-102-00002) 
conducted in parallel with this trial.  Assuming a 30%

(English translation, 06 Aug 2019) 
discontinuation rate in Japanese subjects in a multinational 
phase 3 long-term trial (Trial TV48125-CNS-30051), 
approximately 80 patients receiving TEV-48125 are 
expected to complete the multinational phase 3 confirmatory 
trials (Trials TV48125-CNS-30049 and TV48125-CNS-
30050).  To make up the difference (20 patients), assuming 
the same discontinuation rate of 30% in this trial (Trial 406-
102-00003), it is estimated that 30 patients are needed.  
Considering the possibility that the discontinuation rate may 
exceed 30% in either the multinational phase 3 long-term 
trial or this trial, in order to ensure compliance with the 
criteria contained in the International Council for 
Harmonisation E1 Guideline that 100 subjects complete a 
year of administration, it is considered necessary to enroll 
40 new patients in this trial. 
Trial Duration: 
Overall trial period [for both (1) and (2)]:  Aug 2017 
through Sep 2020 (planned) 
Planned trial participation period for individual subjects (1):  
approximately 589 days 
(Screening period of 4 weeks [28 days], treatment period of 
52 weeks [364 days], and follow-up period of approximately 
197 days) 
Planned trial participation period for individual subjects (2):  
approximately 197 days (follow-up period only)

Introduction 
1.1 
Pathology and Treatment of Migraine 
Migraine is a prevalent condition characterized by attacks of headache (moderate to 
severe pain intensity, unilateral location, and/or pulsating quality) and associated 
symptoms (such as nausea, photophobia, or phonophobia).  Global Burden of Disease 
studies 2015 rank migraine as the seventh highest cause of years lived with disability 
(YLDs) and as the third highest cause of YLDs for ages 15 to 49 years, suggesting that 
the disease not only imposes a considerable disability burden on the daily and social lives 
of affected individuals but it also causes a serious social loss.1 
Episodic migraine (EM) and chronic migraine (CM) are 2 common forms of migraine.  
Individuals with EM have headaches on less than 15 days per month,2 while those with 
CM present with headaches on 15 or more days per month and have migraine on at least 
8 days per month.3  Approximately 3% of individuals with EM evolve, in any given year, 
to a significantly more disabling condition called CM.4,5 
Although the pathophysiology of migraine has yet to be fully elucidated, it is believed 
that a certain stimulus works on the perivascular trigeminal axon, leading to the release of 
vasoactive neuropeptides, which act as neurotransmitters, including substance P and 
calcitonin gene-related peptide (CGRP), from nerve terminals and that this in turn 
triggers neurogenic inflammation around dura mater, contributing to the production of 
pain.6,7,8  CGRP is thus involved in the pathophysiology of migraine.6  Inhibition of 
CGRP has demonstrated efficacy in the treatment of EM and CM.9,10 
Pharmacotherapeutic management of migraine consists of acute treatment and preventive 
treatment.  The goals of acute treatment are to rapidly and certainly relieve attacks of 
migraine and restore the patient’s ability to function.  On the other hand, the goals of 
preventive treatment are:  1) to reduce the frequency, severity, and duration of headache; 
2) to improve response to acute treatment; and 3) to improve life functions and reduce 
disabilities in daily life.11  Currently available drug therapies for preventive treatment of 
migraine include antiepileptic drugs, beta-blockers, antidepressants, angiotensin receptor 
blockers, angiotensin-converting enzyme inhibitors, and calcium channel blockers.  
Medications covered by Japanese health insurance for preventive treatment of migraine 
include lomerizine, valproic acid, propranolol, and dihydroergotamine, for which there 
are varying response rates in their ability to prevent migraine.

1.2 
TEV-48125 
TEV-48125 (also known as PF-04427429, RN307, or LBR-101) is a fully humanized 
immunoglobulin G (IgG) 2a/kappa monoclonal antibody derived from a murine precursor.  
TEV-48125 is a potent, selective CGRP binder and blocks both CGRP isoforms (α- and 
β-CGRP) from binding to the CGRP receptor.  TEV-48125 is specific for CGRP and 
does not bind to the closely related family members amylin, calcitonin, or 
adrenomedullin peptides.  Two mutations were introduced into the constant region of the 
TEV-48125 heavy chain to limit antibody effector functions.  This loss of function 
prevents TEV-48125 from stimulating antibody-dependent cell-mediated cytotoxicity and 
triggering complement-mediated lysis; complement-mediated lysis can lead to unwanted 
consequences such as cell lysis, opsonization, and cytokine release and inflammation.12,13  
With a different mechanism of action from existing migraine prophylactics, TEV-48125 
has acceptable tolerability, as confirmed from both nonclinical and clinical data, and a 
long plasma elimination half-life (t1/2), thus representing a promising therapeutic 
candidate for the preventive treatment of migraine, which is expected to reduce dosing 
frequency compared to existing counterparts and provide an additional treatment option. 
1.3 
Nonclinical Data 
In vivo pharmacology studies of TEV-48125 in animal models indicate that TEV-48125 
prevented an increase in blood flow in rat paw skin and the middle meningeal artery after 
electrical stimulation and produced a dose-dependent inhibition of the capsaicin-induced 
skin flare response in cynomolgus monkeys. 
Safety pharmacology parameters of TEV-48125 were assessed in the toxicology studies 
in Sprague Dawley rats and cynomolgus monkeys and a separate cardiovascular safety 
pharmacology study in male cynomolgus monkeys.  There were no treatment-related 
changes in electrocardiograms (ECGs) and heart rates in the 1- and 3-month toxicity 
studies, and a single intravenous (IV) dose of TEV-48125 at 100 mg/kg did not result in 
changes in cardiovascular parameters or body temperature in monkeys.  Additionally, no 
target organ toxicity was identified.  In these referenced studies, the no-observed-
adverse-effect level (NOAEL) ranged from 100 to 300 mg/kg dosed either intravenously 
or subcutaneously.  In a 3-month monkey study, perivascular inflammation of the ciliary 
artery was observed in a few animals at doses ≥ 100 mg/kg.  The inflammation was 
suspected to be the result of immune complex formation/deposition from the monkeys’ 
immunogenic response to the drug (TEV-48125).  In the 6-month chronic toxicity study 
in monkeys following once-weekly subcutaneous (SC) dosing at dosage levels of up to 
300 mg/kg/week, reaching high exposure throughout the study, no microscopic findings

Version 5.0, 08 Jul 2019 
 
 
(English translation, 06 Aug 2019) 
were noted in any of the organs, including the ciliary vessels of the eyes, and the NOAEL 
of the chronic toxicity study was determined to be the highest dose tested, 
300 mg/kg/week.  Thus, it is believed that in view of the low frequency (ie, observed in 
very few animals) and minimal severity, the finding (perivascular inflammation) that was 
only recorded in the 3-month toxicity study, and had been resolved during the recovery 
period, is an incidental finding. 
The pharmacokinetics of TEV-48125 in animals (rats and monkeys) is the same as that of 
a typical humanized IgG2 antibody, with low mean plasma clearance, low volume of 
distribution at steady state, and a long t1/2.  The maximum observed plasma concentration 
(Cmax) and the area under the plasma concentration-time curve increased linearly across 
doses following single and repeated once-weekly dosing.  No gender differences in 
exposure were observed in rats or monkeys. 
Additionally, reproductive and developmental toxicity studies in rabbits and rats with 
TEV-48125 were conducted and completed.  Preliminary data suggest that weekly dosing 
with TEV-48125 was well tolerated and did not induce any obvious maternal toxicity at 
any dose level.  No apparent evidence of embryo-fetal toxicity was noted in any dose 
group. 
Overall, no toxicological concerns were identified following up to 6 months of dosing to 
the experimental animals. 
1.4 
Clinical Data 
To date, TEV-48125 has been studied in seven phase 1 trials in healthy adults and two 
phase 2b trials in migraine patients.  In total, 532 subjects (166 healthy adults and 366 
migraine patients) received at least 1 dose of TEV-48125 via IV or SC administration.  
Currently, 3 multinational phase 3 trials (Trials TV48125-CNS-30049, TV48125-CNS-
30050, and TV48125-CNS-30051) to further evaluate the efficacy, safety, and tolerability 
of dose regimens of TEV-48125 for the preventive treatment of CM or EM are ongoing. 
1.4.1 
Clinical Pharmacology Trials 
A total of 166 subjects received at least 1 dose of TEV-48125 across 7 completed phase 1 
trials at doses ranging from 0.2 through 2000 mg.  Trials included 2 single-dose-
escalation pharmacokinetic and pharmacodynamic trials in healthy adult men (Trials 
B0141001 and B0141002); a 2-cohort, placebo-controlled, crossover trial to examine the 
acute effects administration of TEV-48125 on capsaicin flare response in healthy adult 
men (Trial B0141006); a parallel-group, repeat-dose trial of TEV-48125 in healthy adult 
men and women (Trial B0141007); a single-dose trial evaluating the safety, tolerability, 

Protocol 406-102-00003

21 
Version 5.0, 08 Jul 2019 
 
 
(English translation, 06 Aug 2019) 
and pharmacokinetics of doses up to 2000 mg administered to healthy adult women (Trial 
LBR-101-008); a single-dose trial comparing the safety, tolerability, absolute 
bioavailability, and pharmacokinetics of SC and IV TEV-48125 in healthy adult men and 
women (Trial LBR-101-011); and a trial evaluating the pharmacokinetics, safety, and 
tolerability of a single SC administration of TEV-48125 in healthy Japanese and 
Caucasian adult men and women (Trial TV48125-PK-10078). 
Based on noncompartmental analysis, TEV-48125 exposure increases with dose in a 
more than dose-proportional manner from 225 to 900 mg following SC administration.  
The time to maximum (peak) plasma concentration (tmax) following SC administration at 
225 to 900 mg ranged from 5 to 7 days with the dose having no observed impact on tmax.  
The mean t1/2 following SC administration ranged from 32.23 to 36.15 days with no 
impact of the dose observed. 
TEV-48125 was well tolerated with favorable safety profile.  The treatment-emergent 
adverse events (TEAEs) reported in the phase 1 trials were predominantly mild or 
moderate in severity.  Neither a specific “pattern of adverse events (AEs)” that was 
thought to be associated with a dose of TEV-48125 nor a maximally tolerated dose was 
identified.  There were no deaths.  One serious adverse event (SAE) reported as “thoracic 
aortic aneurysm aggravated” in an individual receiving a single IV 300-mg TEV-48125 
dose resolved. 
TEV-48125 was not associated with any clinically relevant patterns of change in vital 
signs (systolic and diastolic blood pressure, temperature, and heart rate) or cardiac 
conduction and repolarization (P-R interval, QT interval corrected for heart rate using 
Bazett’s and Fridericia’s formulas) measured by frequent 12-lead ECGs.  No changes in 
liver function tests (aspartate aminotransferase [AST], alanine aminotransferase [ALT], 
total bilirubin, and alkaline phosphatase [ALP]) or differences between TEV-48125 and 
placebo in hematological parameters, tests assessing renal function, electrolytes, or 
urinalysis has been observed in any of the phase 1 trials. 
1.4.2 
Clinical Safety and Efficacy Trials 
The efficacy, safety, tolerability, and pharmacokinetics of TEV-48125 were evaluated in 
migraine patients in two phase 2b trials (Trial LBR-101-021 and Trial LBR-101-022).  
The first trial (Trial LBR-101-021) was a multicenter, randomized, double-blind, 
placebo-controlled, parallel-group trial using TEV-48125 (2 dose levels) in 264 patients 
with CM.  Following a 28-day run-in period, participants were randomized and treated 
SC once monthly for 3 months.  One TEV-48125 group received a first dose of 675 mg 
followed by 225 mg on the subsequent 2 months.  The other TEV-48125 group received

Version 5.0, 08 Jul 2019 
 
 
(English translation, 06 Aug 2019) 
900 mg per month.  The mean change in headache hours relative to baseline for each 
TEV-48125 dose group showed a statistically significant reduction in headache hours 
compared to the placebo group at 3 months (primary endpoint) and reductions also at 1 
and 2 months.  Both doses were also superior to placebo for the secondary endpoint 
(decrease in the number of days with moderate or severe headache at 3 months).  At the 
doses tested, TEV-48125 was well tolerated, and no investigational medicinal product 
(IMP)-related SAEs were reported.  Most TEAEs were mild or moderate.  No safety 
signals were observed in the clinical laboratory tests, vital signs, physical examination, or 
ECGs. 
The other phase 2b trial (Trial LBR-101-022) was a multicenter, randomized, double-
blind, placebo-controlled, parallel-group trial using TEV-48125 (2 dose levels) in 297 
patients with EM.  Following a 28-day run-in period, subjects were randomized and 
treated subcutaneously once monthly for 3 months.  Two doses of TEV-48125 were 
tested, 225 mg given monthly for 3 months, and 675 mg given monthly for 3 months.  
The mean change in number of migraine days relative to baseline for each TEV-48125 
dose group showed a statistically significant reduction in migraine days compared to the 
placebo group at 3 months (primary endpoint), and reductions also at 1, and 2 months.  
Differences in the secondary and exploratory endpoints compared to the placebo group 
were also seen throughout the trial.  Both doses were well tolerated, and no IMP-related 
SAEs were reported.  Most TEAEs were mild or moderate and the lowest dose had a 
numerically lower number of subjects with adverse events relative to placebo.  No safety 
signals were observed in the clinical laboratory tests, vital signs, physical examination, or 
ECGs. 
1.5 
Known and Potential Risks and Benefits 
Identified risks (adverse drug reactions) of TEV-48125 include injection site erythema, 
administration site pain, injection site pain, injection site pruritus, injection site dermatitis, 
infusion-related reaction, and drug hypersensitivity.  Potential risks for TEV-48125 are 
perivascular inflammation; development of antidrug antibodies (ADAs); liver enzyme 
elevations; and cardiovascular consequences of CGRP inhibition, including effects on 
blood pressure, heart rate, or other cardiovascular parameters. 
Subcutaneous TEV-48125 has generally been well tolerated over the ranges of doses 
evaluated (single doses of 0.2 to 2000 mg in healthy adults, multiple doses of 30 to 
300 mg in healthy adults, and multiple doses of 225 to 900 mg in migraine patients).  The 
most common TEAEs were mild to moderate transient general administration site 
disorders/reactions.  Other commonly reported TEAEs were headache, back pain, and 
upper respiratory tract infection.

(English translation, 06 Aug 2019) 
Based on the results from two phase 2b trials (Trials LBR-101-021 and LBR-101-022), in 
patients with CM, the mean change in headache hours relative to baseline for each TEV-
48125 dose group showed a statistically significant reduction in headache hours 
compared to the placebo group at 3 months (primary endpoint) and reductions also at 1 
and 2 months.  In patients with EM, the mean change in migraine days relative to 
baseline for each TEV-48125 dose group showed a statistically significant reduction in 
migraine days compared to the placebo group at 3 months (primary endpoint) and 
improvement at 1 and 2 months.  Furthermore, results for several secondary/exploratory 
endpoints also showed TEV-48125 to be superior to placebo. 
Based on the above safety profile and the demonstrated efficacy of SC TEV-48125, the 
benefits of TEV-48125 are expected to outweigh the risks. 
 
Detailed information is presented in the Investigator’s Brochure.

Trial Rational and Objectives 
2.1 
Trial Rationale 
It has been recommended that preventive treatment of migraine should be continued for 3 
to 6 months if no AEs occur11.  Therefore, even after 6 months have passed since the start 
of treatment, administration of preventive medication is likely to be continued until 
migraine is well controlled.  Considering the potential long-term use of TEV-48125 in 
clinical practice, it is considered necessary to accumulate long-term safety data.  Based 
on the International Council for Harmonisation (ICH) E1 Guidelines,14 data from 100 
Japanese patients treated with TEV-48125 for 1 year is needed to evaluate the long-term 
safety of the drug in Japanese patients. 
Nonclinical studies of TEV-48125 required for the conduct of this trial have been 
completed.  The pharmacokinetics and tolerability of TEV-48125 (IV doses ranging from 
0.2 to 2000 mg and SC doses of 225, 675, and 900 mg) have been well-characterized in 
the phase 1 trials.  Furthermore, the safety and effectiveness of TEV-48125 has been 
demonstrated in a randomized, double-blind, placebo controlled phase 2b trial (Trial 
LBR-101-021) of 2 SC dosing regimens of TEV-48125 (monthly TEV-48125 at 900 mg 
or TEV-48125 at 675 mg followed by monthly TEV-48125 at 225 mg) in patients with 
CM and a randomized, double-blind, placebo-controlled phase 2b trial (Trial LBR-101-
022) of 2 SC dosing regimens of TEV-48125 (monthly TEV-48125 at 675 or 225 mg) in 
patients with EM.  Based on these results, 2 multinational phase 3 confirmatory trials 
(Trials TV48125-CNS-30049 and TV48125-CNS-30050) and a long-term trial (Trial 
TV48125-CNS-30051) are ongoing ahead of this trial.

(English translation, 06 Aug 2019) 
The results of a phase 1 single-dose trial (Trial TV48125-PK-10078) in healthy Japanese 
and Caucasian subjects have demonstrated similarities in the safety profile of TEV-48125 
between the 2 populations, and Japanese patients are enrolled in ongoing multinational 
phase 3 trials (Trials TV48125-CNS-30049, TV48125-CNS-30050, and TV48125-CNS-
30051), which began ahead of this trial.  However, it might be difficult to evaluate the 
long-term safety of TEV-48125 in Japanese patients sufficiently based only on the data 
from a multinational phase 3 long-term trial (Trial TV48125-CNS-30051) in which less 
than 100 Japanese patients are expected to complete a 1-year treatment at the same doses 
and regimens as those specified for phase 2b/3 trials (Trials 406-102-00001 and 406-102-
00002) that are to be conducted in parallel with this trial.  Therefore, it is considered 
necessary to conduct this trial. 
In this trial, in addition to the assessments of long-term safety and tolerability, ADAs to 
TEV-48125 at a time point where plasma TEV-48125 concentrations are considered to be 
sufficiently decreased will be measured during an observation period, in which ADA 
measurements and safety data collection will be conducted in subjects who have 
completed or discontinued either of the phase 2b/3 trials (Trials 406-102-00001 and 406-
102-00002).  Given that TEV-48125, an antibody drug conjugate, may work as an 
antigen and induce ADA production, it is planned to evaluate its immunogenicity and 
effects of ADAs on the pharmacokinetics, efficacy, and safety of TEV-48125 (ADA 
assessment). 
2.2 
Rationale for DNA Storage 
In this trial, deoxyribonucleic acid (DNA) samples will be stored on a voluntary basis.  
Only trial sites that have agreed in advance to collect samples for DNA storage will 
collect the samples from subjects who have provided written informed consent to the 
storage of their DNA samples.  Concerning collecting DNA samples and storing them 
during the trial period, the Ministry of Health, Labour and Welfare states in Q&A15 in 
“Clinical trials based on pharmacogenomics” (Notification No. 0930007 of the 
Evaluation and Licensing Division, Pharmaceutical and Food Safety Bureau issued on 30 
Sep 2008) that samples for genomic/genetic analysis related to the evaluation of an 
investigational product (eg, pharmacokinetic, efficacy, and safety evaluation) may be 
collected from subjects during a clinical trial 1) if the target and time of genomic/genetic 
analysis have been determined when a clinical trial is conducted, or 2) if the target and 
time of genomic/genetic analysis have not yet been determined when a clinical trial is 
conducted but there is a plan to perform such analysis in the future to further characterize 
the investigational product.

In view of the above, it is considered acceptable to store DNA samples for future 
exploration of possible relationships between treatment response to TEV-48125 and 
variations of DNA characteristics (eg, genetic polymorphism). 
Because subjects rolling over from the phase 2b/3 trials (Trials 406-102-00001 and 406-
102-00002) have already been requested consent for DNA storage, this trial will handle 
only newly enrolled subjects as candidate subjects for DNA storage. 
2.3 
Dosing Rationale 
TEV-48125 is a preparation for SC injection.  Given that a preventive drug needs to be 
administered for at least 3 to 6 months to prevent migraine attacks, SC administration, an 
easier dosing modality compared with IV administration, was selected for the 
convenience of use. 
This trial will be conducted to evaluate the long-term safety and tolerability of TEV-
48125 given in accordance with the same regimens as those in the phase 2b/3 trials 
(Trials 406-102-00001 and 406-102-00002) which are conducted in patients with CM and 
EM, respectively, in parallel with this trial.  Similarly to the dose regimens in the phase 
2b/3 trials, TEV-48125 will be administered in this trial subcutaneously at 225 mg once 
monthly (except for a loading dose of 675 mg for CM patients) or at 675 mg once every 
3 months.  The dose regimens in each phase 2b/3 trial were selected based on phase 2b 
trials (Trials LBR-101-021 and LBR-101-022) conducted to evaluate the safety, efficacy, 
and dose regimens of TEV-48125 primarily in patients with migraine.  The doses and 
dosing regimens used in phase 2b trials were selected based on the result that the 225-mg 
dose of TEV-48125 was considered the lowest effective dose as demonstrated in 
nonclinical studies and that the safety of TEV-48125 was confirmed at doses ranging 
from approximately 225 to 900 mg in phase 1 trials. 
In a phase 2b trial in CM patients (Trial LBR-101-021), 2 regimens of 225 mg once 
monthly (except for a loading dose of 675 mg) and 900 mg once monthly were found to 
be effective and well tolerated.  Both TEV-48125 dose groups showed improvement 
compared to the placebo group from Month 1, and the difference from placebo group for 
each TEV-48125 dose group was similar. 
In a phase 2b trial in EM patients (Trial LBR-101-022), 2 regimens of 225 or 675 mg 
once monthly were found to be effective and well tolerated.  Both TEV-48125 dose 
groups showed improvement compared to the placebo group from Month 1, and the 
difference from placebo group for each TEV-48125 dose group was similar.  Based on 
these findings, the lower dose of TEV-48125 used in these phase 2b trials (Trials LBR-
101-021 and LBR-101-022) was considered appropriate for both CM and EM patients in

the phase 2b/3 trials (Trials 406-102-00001 and 406-102-00002) conducted in parallel 
with this trial.  In the lower dose group in the phase 2b trial in CM patients (Trial LBR-
101-021), a loading dose of 675 mg was used despite the lowest effective dose of 225 mg.  
As it is considered best practice to provide appropriate preventive treatment to CM 
patients at an early stage, the phase 2b/3 trial (Trial 406-102-00001) conducted in parallel 
with this trial will also use a loading dose of 675 mg as in the phase 2b trial (Trial LBR-
101-021) to facilitate a rapid onset of effect.  The phase 2b/3 trials (Trials 406-102-00001 
and 406-102-00002) conducted in parallel with this trial will have a TEV-48125 675 mg 
group (dosing once every 3 months) to determine how different doses and dosing 
regimens may affect the efficacy of TEV-48125 in Japanese patients.  This trial will also 
evaluate the safety, tolerability, and efficacy of TEV-48125 in subjects receiving the drug 
once every 3 months at a dose of 675 mg. 
2.4 
Rationale for Treatment Period 
The duration of treatment will be 1 year in accordance with the ICH E1 Guideline.14 
2.5 
Trial Objective 
To evaluate the long-term safety and tolerability of SC administration of TEV-48125 (at 
225 mg once monthly [except for a loading dose of 675 mg in CM patients] or at 675 mg 
every 3 months) as preventive treatment for CM or EM patients.

Trial Design 
3.1 
Type/Design of Trial 
This is a multicenter, randomized, open-label trial in patients with CM or EM.  The 
schematic of the trial design is shown in Figure 3.1-1. 
The trial consists of a 4-week screening period, a 52-week treatment period, and a follow-
up period of 225 days after the final dose of IMP.  In the trial, treatment period is defined 
as up to 4 weeks after the final dose of IMP.  The trial has a follow-up period after the 
end of treatment to allow ADA assessment to be performed. 
After obtaining written informed consent from patients, the investigator will screen them 
for eligibility (Visit [V] 1/Screening).  Subjects who meet all the inclusion criteria and do 
not fall under any of the exclusion criteria will be randomized at V2/Baseline in a 1:1 
ratio to receive one of the 2 treatments shown below for CM or EM.  In any treatment 
group, the IMP will be administered according to each dosing method specified below 
from V2/Baseline to V14/Month 12 and the final assessment will be performed at 
V15/End of treatment as an end of treatment visit.  Subjects will return to the trial site for

Version 5.0, 08 Jul 2019 
 
 
(English translation, 06 Aug 2019) 
ADA assessment 225 days (the approximate equivalent of 5 half-lives of TEV-48125) 
after the final dose of IMP (V16/Follow-up).  Subjects who withdraw from the trial will 
undergo evaluation at withdrawal and return to the trial site for ADA assessment 225 
days after the final dose of IMP (V16/Follow-up). 
The treatment groups in this trial are as follows: 
[CM] 
 TEV-48125 225 mg/1 month group 
 TEV-48125 675 mg/3 months group 
 
[EM] 
 TEV-48125 225 mg/1 month group 
 TEV-48125 675 mg/3 months group 
 
Those who complete or discontinue either of the phase 2b/3 trials (Trials 406-102-00001 
and 406-102-00002) will also be enrolled in this trial for the purpose of evaluating ADAs 
(subjects enrolled for ADA assessment only). 
The investigator will obtain written informed consent to ADA assessment from these 
subjects and instruct them to return for ADA assessment 225 days after the final dose of 
IMP has been administered in either of the phase 2b/3 trials (Trials 406-102-00001 and 
406-102-00002) (V16/Follow-up).  In this trial, the IMP will not be administered to 
subjects enrolled for ADA assessment only. 
 
The period of trial participation for each subject is defined as the period from the day that 
informed consent is obtained from the patient until the day of trial completion. 
Definition of the end of trial date for individual subject: 
The end of trial date for individual subject is defined as the date of V16/Follow-up for the 
final assessment/observation.  For subjects who become lost to follow-up, the end of trial 
date for individual subject is defined as the date of their last visit/contact or the date of 
the last attempt to contact them. 
If a new drug application is filed based on the results of the phase 2b/3 trials (Trials 406-
102-00001 and 406-102-00002) before the end of this trial, an interim analysis of this 
trial will be performed.

Trial Treatments 
The IMP will be subcutaneously administered by clinical trial personnel responsible for 
administration of injections.  The IMP will be administered once every 4 weeks 
(acceptable window:  ± 5 days) for a total of 13 doses (at 225 mg once monthly [except 
for a loading dose of 675 mg in subjects with CM]) or every 12 weeks (acceptable 
window:  ± 5 days) for a total of 5 doses (at 675 mg once every 3 months).  For this trial, 
1 month refers to 4 weeks.  Subjects who visit the trial site earlier than the acceptable 
window will not receive the IMP and will be requested to return to the trial site within the 
acceptable window.

V14/Month 12. 
 
At the time of each visit, the Interactive Response Technology (IRT) will be queried and 
trial personnel will retrieve and administer a 1.5-mL volume from each syringe contained 
in the appropriately numbered kit(s). 
Recommended SC injection sites follow the National Institutes of Health clinical center 
patient education materials:  Giving a subcutaneous injection.16  The suggested sites of 
injection are the outside of upper arms, back of upper arms, abdomen, or front of thighs.  
At each visit and when 3 injections are administered at a visit, each of the injections 
should be given in a different location (eg, not in precisely the same place).  Trial 
personnel responsible for administration of injections should inspect previous injection 
sites to ensure that they are free from bruising and tenderness and that proper rotation of 
sites is performed. 
IMP should be removed from the refrigerator and allowed to equilibrate at room 
temperature for 45 to 60 minutes before IMP administration. 
The date and time of SC injections and their location will be recorded for each dosing 
visit. 
The IMP will not be administered to subjects enrolled for ADA assessment only. 
3.3 
Trial Population 
3.3.1 
Number of Subjects and Description of Population 
A total of 40 males or females with CM or EM aged 18 to 70 years, inclusive, will be 
enrolled in the trial.  Of them, approximately 30 are expected to complete the trial.  The 
enrollment procedure will be continued until the number of enrolled subjects reaches 40. 
Up to 966 subjects who have completed or discontinued either of the phase 2b/3 trials in 
patients with CM or EM (Trials 406-102-00001 and 406-102-00002) will be enrolled in 
this trial solely for the purpose of ADA assessment (the IMP will not be administered to 
these subjects in this trial).  Of these, approximately 644 subjects who have received 
TEV-48125 in either of the phase 2b/3 trials will undergo ADA assessment. 
3.3.2 
 
Subject Selection and Numbering 
After informed consent is obtained, subjects will be assigned a unique subject 
identification number (site number [3 digits] + S + subject number [5-digit in-site serial 
number]).  The site number (3 digits) will be designated by the sponsor.  The subject 
number (5-digit in-site serial number) will be given at each trial site in the chronological

order informed consent is obtained in, starting at 30001.  Following screening, subjects 
who fail to meet the eligibility criteria will be handled as screen failures.  Trial sites will 
prepare and retain a list of all consented subjects and their subject identification numbers. 
3.4 
Eligibility Criteria 
3.4.1 
Informed Consent 
Written informed consent will be freely obtained from all subjects (or legally acceptable 
representative, etc, if the subject is a minor).  Consent will be documented on a written 
informed consent form (ICF).  The written information for subjects and ICF will be 
approved by the same institutional review board or independent ethics committee/ethics 
committee (IRB/IEC/EC) that approves this protocol. 
Each information for subjects and ICF will comply with the ICH (International 
Conference on Harmonisation) Good Clinical Practice (GCP) Guideline17 and local 
regulatory requirements.  The principal investigator will ensure that the sponsor reviews 
and authorizes any written site-specific ICF used in the trial before submission to the 
IRB/IEC/EC. 
Investigators may discuss trial availability and the possibility for entry with a potential 
subject without first obtaining consent.  However, informed consent must be obtained and 
documented before initiation of any procedures that are performed solely for the purpose 
of determining eligibility for this trial, including withdrawal from current medication(s). 
Potential subjects are free to refuse entry into the trial, or withdraw from the trial at any 
time, without justification, and there will be no consequences to their further care. 
Once appropriate essential information has been provided and fully explained in 
layman’s language to the subject by the investigator (or a qualified designee), and it has 
been documented that the subject has had the opportunity to ask questions, the IRB- or 
IEC/EC-approved written ICF will be signed and dated by both the subject and the person 
obtaining consent (investigator or designee who gave the explanation), as well as by any 
other parties required by the IRB/IEC/EC.  The subject (or legally acceptable 
representative, etc, if the subject is a minor) will receive the written information for 
subjects and a copy of the signed ICF; the original shall be kept on file by the investigator. 
Subjects may be asked to sign additional ICFs if the protocol is amended to significantly 
add or change procedures. 
For DNA storage, written informed consent will be freely obtained from subjects (or 
legally acceptable representative, etc, if the subject is a minor) using a separate written 
information for subjects, by following the above-mentioned procedure.  DNA samples

(English translation, 06 Aug 2019) 
will be stored on a voluntary basis, and subject’s refusal to participate in DNA storage 
will not affect their participation in the main trial. 
If a potential subject is a minor, written informed consent will be freely obtained from his 
or her legally acceptable representative, as applicable for local laws.  If the investigator 
decides that the potential subject is able to understand the explanation of the trial, 
however, the potential subject will be given an explanation appropriate to his or her 
ability to understand and then sign and date the ICF by himself or herself.

3.7.1.1 
Screening Period 
The screening period begins on the day of informed consent and ends on the day before 
V2/Baseline. 
An appropriately signed and dated ICF will be obtained before screening procedures 
commence.  After informed consent is obtained, the investigator (or designee) will 
promptly enter the subject’s information in the IRT and obtain a subject identification 
number as described in Section 3.3.2, Subject Selection and Numbering. 
The following information will be recorded on the case report form (CRF): 
 Informed consent 
 
Date of informed consent 
 
Subject identification number 
For headache information on each day from V1/Screening through the day before 
V2/Baseline, subjects will enter headache information about the previous day into the 
electronic headache diary.  The data used for inclusion criterion 5 will be those from the 
electronic headache diary within the last 28 days prior to V2/Baseline. 
12-Lead ECGs and clinical laboratory values measured by the central laboratory, which 
cannot be assessed at V1/Screening, should be checked against inclusion/exclusion 
criteria soon after they become available to determine the subject’s eligibility. 
3.7.1.1.1 
Visit 1/Screening (Day −28; Acceptable Window:  −5 Days) 
V1/Screening will take place 28 days before V2/Baseline.  In order to determine the 
subject’s eligibility, the following assessments/tests/observations will be performed and 
recorded on the CRF.

Efficacy Assessment 
Any efficacy endpoint data will be electronically collected.  Data on headache-related 
efficacy endpoints will be collected using eDiary, and data on overall functional 
assessments, physical assessments, and other relevant assessments (Section 3.7.2.2 
through Section 3.7.2.8) will be collected using Electronic Patient-Reported Outcomes 
(ePRO). 
3.7.2.1 
Electronic Headache Diary 
Headache-related efficacy endpoints will be derived from headache variables collected 
using an eDiary.  Eligible subjects will receive comprehensive training from trial 
personnel on the use of the eDiary at V1/Screening.  On each day, the subject will be 
asked to enter headache data in the electronic headache diary for the previous 24-hour 
period.  Subjects who report headache on the previous day will answer questions about

the headache (ie, occurrence of headache, duration of headache, maximum severity of 
headache, presence/absence of associated symptoms, and use of acute headache 
medications). 
Headache data for the preceding day should be entered into the electronic headache diary 
by the data entry time limit of 2 days (48 hours).  If this time limit is exceeded, the 
subject will not be able to enter headache information for the applicable day, and it will 
be considered a missing day.  If a subject has not entered the headache data by 8 PM of 
the next day, the subject will be reminded to enter the data. 
Overall headache duration will be recorded numerically, in hours, as well as number of 
hours with headache of at least moderate severity. 
If headache is reported, then headache severity will be subjectively rated by the subject as 
follows: 
 Mild headache 
 Moderate headache 
 Severe headache 
Subjects will also record the presence or absence of photophobia, phonophobia, nausea, 
or vomiting, and the status of use of any acute headache medications. 
3.7.2.2 
Six-Item Headache Impact Test (Subjects With CM Only)  
The investigator will instruct subjects to complete the HIT-6 to assess the impact of 
headache on their social functioning, role functioning, vitality, cognitive functioning, and 
psychological distress.  Only subjects with CM will be required to complete the HIT-6. 
3.7.2.3 
Migraine Disability Assessment Questionnaire (Subjects With 
EM Only)  
The investigator will instruct subjects to complete the MIDAS questionnaire to assess the 
degree of headache-related disability based on lost days of activity in 3 domains (work, 
household work, and nonwork) over the last 3 months.  The MIDAS questionnaire is a 5-
item instrument.  The total of the scores of the first 5 questions is used for grading the 
level of disability, with scores of 0 to 5, 6 to 10, 11 to 20, and ≥ 21 interpreted as 
disability grades I (little or no disability), II (mild disability), III (moderate disability), 
and IV (severe disability), respectively.  Only subjects with EM will be required to 
complete the MIDAS questionnaire.

Two-Item Patient Health Questionnaire/Nine-Item Patient Health 
Questionnaire 
The investigator will instruct subjects to complete PHQ-2 and PHQ-9 for detection and 
monitoring depression, anxiety, and somatization during the last 2 weeks.  The PHQ is a 
9-item questionnaire with each item corresponding to 1 criterion of the Diagnostic and 
Statistical Manual for Mental Disorders fourth edition diagnostic criteria for major 
depressive disorder.  Each of the items is scored on a scale of 0 (not at all), 1 (several 
days), 2 (more than half the days), and 3 (nearly every day) based on the frequency of 
symptoms during the past 2 weeks.  The PHQ-2 was developed from the PHQ-9 to 
rapidly screen for depression and consists of the first 2 questions from the PHQ-9. 
All subjects will complete the PHQ-2.  If the PHQ-2 is positive (ie, a score of ≥ 3), 
subjects will complete questions 3 through 9 (unique questions) of the PHQ-9. 
3.7.2.5 
Migraine-Specific Quality of Life Questionnaire 
The investigator will instruct subjects to complete the MSQOL questionnaire to assess 
the impact of migraine and migraine treatment on their quality of life during the past 4 
weeks.  The MSQOL measures the degree to which performance of normal activities is 
limited by migraine (Role Function-Restrictive domain comprising 7 items), the degree to 
which performance of normal activities is prevented by migraine (Role Function-
Preventive domain comprising 4 items), and the emotional effects of migraine (Emotional 
Function domain comprising 3 items).  Scores range from 0 to 100, with higher scores 
indicating better health-related quality of life. 
3.7.2.6 
EuroQol-5 Dimension, 5 Response Level Version Questionnaire 
The investigator will instruct subjects to complete the EQ-5D-5L questionnaire to assess 
their overall state of health on the day of assessment.  The EQ-5D-5L questionnaire 
consists of 2 parts.  In Part 1, subjects rate their health state in 5 domains:  mobility, self-
care, usual activities, pain/discomfort, and anxiety/depression, using a scale of 1 to 5 
where 1 = no problems, 2 = slight problems, 3 = moderate problems, 4 = severe problems, 
and 5 = extreme problems.  In Part 2, subjects rate their health state on a 100-mm visual 
analog scale; a rating of 0 represents the worst imaginable health state, and a rating of 
100 represents the best imaginable health state. 
3.7.2.7 
Patient Global Impression of Change Scale 
The investigator will instruct subjects to complete the PGIC scale to assess overall 
change in the severity of illness following treatment.  Subjects will rate how they 
describe the change (if any) that their migraine/headaches have had in their general 
quality of life and health status since beginning the treatment in this trial on a 7-point

scale where 1 = no change (or it got worse); 2 = almost the same, hardly any change at 
all; 3 = a little better, but no noticeable change; 4 = somewhat better, but the change has 
not made any real difference; 5 = moderately better, and a slight but noticeable change; 
6 = better, and a definite improvement that has made a real and worthwhile difference; 
and 7 = a great deal better, and a considerable improvement that has made all the 
difference. 
3.7.2.8 
Work Productivity and Activity Impairment Questionnaire 
The investigator will instruct subjects to complete the generic version of the WPAI 
questionnaire to assess the overall effect of health on productivity at work and daily 
activities during the past 7 days prior to the assessment day.  The investigator will also 
instruct subjects to complete the specific health problems version of the WPAI 
questionnaire, which allows investigators to attribute productivity and activity 
impairment issues to specific health conditions.  After the employment status of a 
respondent is identified, 3 open-ended questions are asked concerning 1) hours absent 
from work due to health problems (or specific condition), 2) hours absent from work due 
to other reasons, and 3) hours actually worked.  Two additional questions are included 
that ask about the impact of health on productivity, one concerning productivity at work 
and the other concerning daily activities outside of work.  The response format of each 
item of the WPAI questionnaire consists of an 11-point scale ranging from 0 (no 
impairment) to 10 (complete impairment).

Clinical Laboratory Assessments 
Clinical laboratory assessments will be performed for the parameters listed in Table 
3.7.3.2-1.  The total volume of blood to be collected for each subject in this trial is 
approximately 109.2 mL. 
All clinical laboratory tests in this trial, excluding urine HCG tests, will be performed 
using the central laboratory selected by the sponsor.  The investigator will confirm the 
eligibility of each subject based on clinical laboratory values measured by the central 
laboratory.  Any additional clinical laboratory tests, if required besides those performed 
at scheduled time points for blood/urine collection for reasons such as AEs, will also be 
performed by the protocol-specified central laboratory.  The collection, treatment, storage,

and shipment of samples will be performed as described in a separate operational 
procedure. 
For WOCBP, a serum HCG test will be performed at V1/Screening and a urine HCG test 
will be performed at V2/Baseline and all subsequent visits.  If a urine HCG test 
performed at V3/Month 1 or any later visit is positive, the investigator will follow up 
with a confirmatory serum HCG test.  For women who have been postmenopausal for at 
least 12 months since last menses, an FSH test will be performed at V1/Screening. 
The central laboratory will report clinical laboratory test results to the investigator.  The 
investigator will confirm the results promptly, and date and sign the clinical laboratory 
test results report as an official document.  The date and time of blood/urine collection 
and whether during menses or not will be recorded on the CRF.  The results of clinical 
laboratory tests, excluding urine HCG tests, will be directly reported from the central 
laboratory to the sponsor via electronic file transfer; therefore, recording of the results on 
the CRF is not needed.  The results of urine HCG tests will be recorded on the CRF.

musculoskeletal; skin; lymph nodes; and neurological.  Physical examinations of 
individual subjects will be performed by the same site personnel to the extent possible.  
On the CRF, the date and results of assessments will be recorded at V1/Screening, and 
only the date of assessments will be recorded at V2/Baseline and subsequent visits.  Any 
clinically significant physical finding that is not observed at V1/Screening but at

V2/Baseline or any later visit will be considered an AE, recorded on the source 
documents and CRFs, and monitored until its outcome has been sufficiently evaluated. 
3.7.3.4 
Height and Weight 
Weight will be measured while minimizing fluctuations associated with clothing.  Date of 
measurement, height (up to one decimal place; cm), and weight (up to one decimal place; 
kg) will be recorded on the CRF.  Any height/weight measured up to more than one 
decimal place will be rounded up to one decimal place. 
3.7.3.5 
Vital Signs 
As vital signs, systolic and diastolic blood pressure, pulse rate, body temperature, and 
respiratory rate will be measured before other assessments (blood draws and 
questionnaires).  Before pulse rate and blood pressure are measured, the subject must be 
in a supine or semi-standing/sitting position and resting for at least 5 minutes.  The same 
position and arm should be used each time vital signs are measured for a given subject 
(however, if it is difficult to use the same position and arm due to occurrence of an AE, 
use of a different position or arm is acceptable).  Date of measurement, position, location, 
pulse rate (integer; beats/min), systolic and diastolic blood pressures (integer; mmHg), 
temperature (up to one decimal place; ºC), and respiratory rate (integer; breaths/min) will 
be recorded on the CRF.  Any vital sign value, excluding temperature, which is measured 
up to one decimal place or more will be rounded to the closest whole number, and any 
temperature value measured up to more than one decimal place will be rounded to one 
decimal place. 
3.7.3.6 
Twelve-lead Electrocardiography 
Using 12-lead ECG equipment provided by the central laboratory selected by the sponsor, 
ECGs will be conducted before other assessments (blood draws and questionnaires).  The 
ECGs should be performed after the subject has been supine for at least 5 minutes. 
Clinical evaluation of ECG results will be performed by the investigator.  A qualified 
physician at the central laboratory selected by the sponsor will interpret ECG results.  
ECGs will be measured and transmitted in accordance with a separate operational 
procedure.  If clinically significant ECG findings are detected by the investigator, a 
medical advisor should be consulted for a definitive interpretation.  Any unscheduled 
ECGs must also be transmitted to the designated central laboratory.  The central 
laboratory will report the results of ECGs to the investigator.  The investigator will 
confirm the results promptly, and date and sign the electrocardiogram report as an official 
document.  Date of ECG and the interpretation of the investigator will be recorded on the 
CRF.  The central ECG interpretations and findings will be directly reported from the

central laboratory to the sponsor via electronic file transfer; therefore, recording of the 
results on the CRF is not needed. 
3.7.3.7 
Electronic Columbia-Suicide Severity Rating Scale (eC-SSRS) 
The eC-SSRS will be used to assess the subject’s suicidal ideation (severity and intensity) 
and suicidal behavior.19  The investigator will ask the subject to complete the eC-SSRS 
Baseline/Screening version at V2/Baseline and the eC-SSRS Since Last Visit version at 
all other time points.  Any positive findings on the eC-SSRS Baseline/Screening version 
or the eC-SSRS Since Last Visit version require evaluation by the investigator. 
3.7.3.8 
Injection Site Reaction Assessments 
Injection site reaction assessments will be performed immediately and 1 hour after each 
IMP administration.  The injection site(s) will be assessed for erythema, induration, 
ecchymosis, and pain, and severity will be graded according to the following criteria.  If a 
subject has severe injection site erythema, induration, and/or ecchymosis and/or grade 3 
(severe) or grade 4 (worst possible) injection site pain at 1 hour after completion of IMP 
administration, the subject will be reassessed hourly thereafter until the reaction/pain is of 
moderate or less severity. 
 Injection-site erythema, induration, and ecchymosis will be graded according to 
measurements: 
absent, 5 to ≤ 50 mm (mild), > 50 to ≤ 100 mm (moderate), and > 100 mm (severe).  
Induration must be assessed by careful superficial palpation avoiding pressuring or 
squeezing the injection site. 
 Injection-site pain will be evaluated according to Table 3.7.3.8-1. 
For injection site assessments, the date and time and results of evaluation will be 
recorded on the CRF, and an injection site reaction (mild, moderate, or severe) is to be 
reported as an AE.  Pain caused by the puncture of the injection needle will be excluded 
from the assessment, and is not considered to be an AE.

Prior and Concomitant Therapy or Medication 
Monitoring will be performed on any prior or concomitant preventive migraine 
medication (including topiramate and onabotulinumtoxin A) that a subject takes during 
the period from 2 years before the start of IMP administration to the end of trial date for 
individual subject (including reasons for discontinuation if any of such medications has 
been discontinued before informed consent) and any other prior or concomitant 
medication or therapy that a subject takes during the period from 5 months before the 
start of IMP administration and up to the end of trial period.  For each medication or 
therapy, the following information will be recorded on the CRF:  name, indication, dose, 
frequency, route of administration, start date, and end date.

Pharmacokinetic Blood Samples 
(1) 
Timing of Blood Sampling 
 V2/Baseline (Day 1):  Predose 
 V5/Month 3 (Day 85; acceptable window:  ± 5 days):  Predose 
 V8/Month 6 (Day 169; acceptable window:  ± 5 days):  Predose 
 V14/Month 12 (Day 337; acceptable window:  ± 5 days):  Predose 
 V15/End of treatment (Day 365; acceptable window:  ± 5 days) 
 Withdrawal (acceptable window:  day of withdrawal decision + 7 days) 
 V16/Follow-up (225 days after the final dose of IMP, acceptable window:  ± 15 days) 
From V2/Baseline through V15/End of treatment, blood will be collected only from 
newly enrolled subjects who are to be treated with the IMP in this trial.  At V16/Follow-
up, blood will be collected from subjects enrolled solely for ADA assessment 225 days 
(acceptable window:  ± 15 days, the approximate equivalent of 5 half-lives of TEV-
48125) after the final dose of IMP in either of the phase 2b/3 trials (Trials 406-102-00001 
and 406-102-00002).

Blood Sampling and Measurement Methods 
Blood will be collected at the scheduled time points to obtain pharmacokinetic plasma 
samples.  The central laboratory will collect samples and transport them to the drug 
concentration measurement facility.  Detailed sample handling and shipping instructions 
are provided in Appendix 1. 
The drug concentration measurement facility will measure plasma concentrations of 
TEV-48125 in subjects treated with TEV-48125, using a validated measurement method.

(English translation, 06 Aug 2019) 
The drug concentration measurement facility will submit the electronic file of the results 
of drug concentration measurements to the sponsor. 
Blood sampling status (performed or not) and date and time of blood sampling will be 
recorded on the CRF.  The results of measurements will be directly reported from the 
drug concentration measurement facility to the sponsor; therefore, recording of the results 
on the CRF is not needed. 
(3) 
Rationale for Timing of Blood Sampling 
In order to evaluate effects of ADA on plasma concentrations of TEV-48125, it is 
planned to collect blood at the same time points as V2/Baseline, V5/Month 3, V8/Month 
6, V14/Month 12, V15/End of treatment, withdrawal, and V16/Follow-up, at which 
ADAs will be measured.  Consequently, blood will be collected from each subject at a 
maximum of 6 time points.

 V14/Month 12 (Day 337; acceptable window:  ± 5 days):  Predose 
 V15/End of treatment (Day 365; acceptable window:  ± 5 days) 
 Withdrawal (acceptable window:  day of withdrawal decision + 7 days) 
 V16/Follow-up (225 days after the final dose of IMP, acceptable window:  ± 15 days)  
 Upon observation of any severe hypersensitivity reaction (eg, anaphylaxis) 
From V2/Baseline through V15/End of treatment, blood will be collected only from 
newly enrolled subjects who are to be treated with the IMP in this trial.  At V16/Follow-
up, blood will be collected from subjects enrolled solely for ADA assessment in order to 
evaluate the immunogenicity at 225 days (acceptable window:  ± 15 days, the 
approximate equivalent of 5 half-lives of TEV-48125) after the final dose of IMP in 
either of the phase 2b/3 trials (Trials 406-102-00001 and 406-102-00002). 
See Appendix 2 for the clinical criteria for diagnosing anaphylaxis.

Blood Sampling and Measurement Methods 
Blood will be collected at the scheduled time points to obtain serum samples for ADA 
assessments.  The central laboratory will collect samples and transport them to the ADA 
measurement facility.  Detailed sample handling and shipping instructions are provided in 
Appendix 1.

The ADA measurement facility will measure anti-TEV-48125 antibodies in serum 
samples collected from subjects treated with TEV-48125, using a validated measurement 
method.  The ADA measurement facility will submit the electronic file of the results of 
ADA measurements to the sponsor. 
Blood sampling status (performed or not) and date and time of blood sampling will be 
recorded on the CRF.  The results of measurements will be directly reported from the 
ADA measurement facility to the sponsor; therefore, recording of the results on the CRF 
is not needed. 
(3) 
Rationale for Timing of Blood Sampling 
It was determined to collect blood at 1 time point before the first dose as baseline; 2 time 
points, V5/Month 3 and V8/Month 6, with an interval of 3 months, which is longer than 
the sampling interval evaluated for the phase 2b/3 trials (Trials 406-102-00001 and 406-
102-00002); and 1 time point, V14/Month 12, with an interval of 6 months.  In addition, 
blood will be collected at 1 time point, V15/End of treatment, which is 28 days after the 
final dose of IMP in consideration of assessment time points recommended in the Food 
and Drug Administration Guidance20 (approximately 30 days after the final dose) and the 
European Medicine Agency Guidelines21 (at least 4 weeks after the final dose).  In 
consideration of the potential effect of the residual drug in the blood on ADA assessment, 
blood will also be sampled at 1 time point, 225 days after the final dose of IMP, when 
plasma TEV-48125 concentrations are considered to be sufficiently decreased.  
Furthermore, blood will be collected at withdrawal.  Consequently, blood will be 
collected from each subject at a maximum of 6 time points (a single time point for 
subjects enrolled for ADA assessment only). 
3.7.4.3 
Pharmacogenomics 
3.7.4.3.1 
DNA Storage 
(1) 
Objectives 
DNA will be stored to analyze CGRP and migraine-associated genes and to thereby 
examine their association with clinical treatment responses to TEV-48125 and their 
potential to be markers predictive of migraine severity and progression (eg, efficacy, 
pharmacokinetics, tolerability, and safety features or disease susceptibility and severity 
features). 
(2) 
Target Patients 
Only trial sites that have agreed in advance to collect samples for DNA storage will 
collect the samples from subjects who have provided written informed consent to the 
storage of their DNA samples among the subjects who receive IMP in this trial.  DNA 
storage will not be performed for subjects enrolled for ADA assessment only.  DNA

(English translation, 06 Aug 2019) 
storage is voluntary.  Even if a subject withdraws his/her consent to trial participation, the 
subject is not regarded as withdrawing his/her consent to DNA storage.  DNA samples 
will be stored only if approval for DNA storage is obtained from the IRB/IEC/EC of a 
trial site.  Consent to DNA storage will be obtained from subjects before blood is 
collected for DNA storage. 
(3) 
Timing of Blood Sampling 
 V2/Baseline (Day 1) or any of subsequent visits:  Predose 
 
(4) 
Blood Sampling and Storage Methods 
Blood will be collected at the scheduled time points to obtain blood samples for DNA 
storage.  The central laboratory will collect samples and assign a new personal code to 
each sample to make it double-coded.  Then, DNA will be extracted from these samples.  
The central laboratory will transport DNA samples to the sample storage facility to store 
DNA.  DNA samples will be stored until either when 1) genomic/genetic analysis is 
judged to be no longer necessary, 2) 15 years have passed since informed consent was 
obtained from the last subject, or 3) a subject withdraws consent for DNA storage, 
whichever is earlier.  Upon request for destruction from the sponsor, the sample storage 
facility will destroy DNA samples in accordance with the relevant procedure specified by 
the facility. 
Detailed procedures related to DNA samples are provided in Appendix 1.  Blood 
sampling status (performed or not) and the date and time of blood sampling will be 
recorded on the CRF. 
(5) 
Genomic/Genetic Analysis 
Genomic/genetic analysis is performed only if it is considered useful to analyze CGRP 
and migraine-associated genes and to thereby examine their association with clinical 
treatment responses to TEV-48125 and their potential to be markers predictive of 
migraine severity and progression (eg, efficacy, pharmacokinetics, tolerability, and safety 
features or disease susceptibility and severity features).  If it is decided that 
genomic/genetic analysis is to be carried out, it will be performed in accordance with 
GCP after preparation of a separate protocol for pharmacogenomic research.  The results 
of the analysis will not be included in the clinical study report but in the 
pharmacogenomic research report that is separately prepared. 
Although target genes for genomic/genetic analysis may be genes having a potential 
association with CGRP and migraine, they are difficult to identify at this stage.  
Genomic/genetic analysis may include genome-wide association analysis performed 
using devices such as DNA chips, microarrays, and next-generation sequencers.  Also in

(English translation, 06 Aug 2019) 
this case, the results will not be used for any purposes other than those presented in 
Section 3.7.4.3.1 (1), Objectives.  The genomic/genetic analysis facility will report the 
results of genomic/genetic analysis of double-coded samples to the sponsor. 
Even if a subject withdraws from participation in the trial at his/her own request, the 
results of genomic/genetic analysis which have already been obtained before withdrawal 
will not be destroyed. 
(6) 
Disclosure of the Results of Genomic/Genetic Analysis 
As a result of genomic/genetic analysis, some genetic association may be found.  
However, the resulting findings would be exploratory in nature or at an early stage of 
research without sufficient scientific reliability in terms of accuracy, certainty, and other 
relevant elements.  Given that the disclosure of scientifically ambiguous information 
would provide no benefits to subjects, the sponsor will not disclose the results of 
genomic/genetic analysis to subjects. 
(7) 
Obtainment and Withdrawal of Consent to DNA Storage 
Subjects will be asked to sign the ICF for DNA storage and genomic/genetic analysis 
using stored DNA samples.  This consent form is prepared separately from the ICF for 
the trial.  If a subject withdraws his/her consent to DNA storage during the DNA storage 
period, the sponsor will ask the sample storage facility to destroy the DNA sample from 
the subject.  A subject’s withdrawal from trial participation is not to be regarded as 
withdrawal of his/her consent to DNA storage.  Upon request for destruction from the 
sponsor, the sample storage facility will destroy relevant DNA samples while maintaining 
their anonymity.  Even if a subject withdraws from participation in the trial at his/her own 
request, the results of genomic/genetic analysis which have already been obtained before 
withdrawal will not be destroyed. 
3.7.4.4 
Biomarkers 
(1) 
Objectives 
Exploratory analysis may be conducted on inflammatory endpoints in blood to examine 
effects of TEV-48125 in patients with migraine.  In addition, exploratory analysis of 
TEV-48125-related biomarkers may be conducted in terms of blood and urine biomarkers 
for extracellular matrix turnover, bone formation, bone resorption, and angiogenesis, in 
which involvement of CGRP is suspected.  Biomarker samples will be stored for these 
exploratory analyses. 
(2) 
Timing of Sampling 
 V2/Baseline (Day 1):  Predose 
 V8/Month 6 (Day 169; acceptable window:  ± 5 days):  Predose  
 V14/Month 12 (Day 337; acceptable window:  ± 5 days):  Predose

 V16/Follow-up (225 days after the final dose of IMP, acceptable window:  ± 15 days)  
 
(3) 
Sampling and Storage Methods 
Blood and urine will be collected at the scheduled time points to obtain biomarker 
samples (plasma, serum, ribonucleic acid [RNA], urine).  The central laboratory will 
collect samples and transport them to a sample storage facility.  Biomarker samples will 
be stored until either when 1) exploratory biomarker analysis is judged to be no longer 
necessary or 2) 15 years have passed since informed consent was obtained from the last 
subject, whichever is earlier.  Upon request for destruction from the sponsor, the sample 
storage facility will destroy relevant biomarker samples. 
Detailed procedures related to biomarker samples are provided in Appendix 1.  
Blood/urine sampling status (performed or not) and the date and time of blood/urine 
sampling will be recorded on the CRF. 
(4) 
Exploratory Biomarker Analysis 
Exploratory biomarker analysis is performed only if it is considered useful to analyze the 
relationship between effects of TEV-48125 in patients with migraine and inflammatory 
endpoints in blood and between TEV-48125 and blood and urine biomarkers for 
extracellular matrix turnover, bone formation, bone resorption, and angiogenesis, in 
which involvement of CGRP is suspected.  If it is decided to carry out exploratory 
biomarker analysis, it will be performed in accordance with GCP after preparation of a 
separate protocol for exploratory biomarker analysis.  The results of the analysis will not 
be included in the clinical study report but in the exploratory biomarker analysis report 
that is separately prepared. 
While target biomarkers for exploratory biomarker analysis may be biomarkers for 
inflammation in blood, blood and urine biomarkers for extracellular matrix turnover, 
bone formation, or bone resorption, or blood biomarkers for endothelial generation or 
angiogenesis, they are difficult to identify at this stage.  Extensive analysis may also be 
performed using a simultaneous multiple measurement panel.  Also in this case, the 
results will not be used for any purposes other than those presented in Section 3.7.4.4 (1), 
Objectives. 
Even if a subject withdraws from participation in the trial at his/her own request, the 
results of exploratory biomarker analysis which have already been obtained before 
withdrawal will not be destroyed.

End of Trial 
The end of trial date for this trial is defined as the date of the last visit/contact or the date 
of the last attempt to contact, which is to be recorded on the follow-up page of the CRF 
prepared for the last subject who completes the trial (the end of trial date for individual 
subject is defined in Section 3.1, Type/Design of Trial). 
3.8 
Stopping Rules, Withdrawal Criteria, and Procedures 
3.8.1 
Discontinuation of Entire Trial 
If the sponsor terminates or suspends the trial for any reason, prompt notification will be 
given to principal investigators, IRBs/IECs/ECs, and regulatory authorities in accordance 
with regulatory requirements. 
3.8.2 
Discontinuation at Individual Sites 
Individual trial site participation may be discontinued by the sponsor, the principal 
investigator, or the IRB/IEC/EC if judged to be necessary for medical, safety, regulatory, 
ethical, or other reasons consistent with applicable laws, regulations, and GCP.  The 
principal investigator will notify the sponsor promptly if the trial is terminated by the 
principal investigator or the IRB/IEC/EC at the trial site. 
3.8.3 
Individual Subject Discontinuation 
3.8.3.1 
Treatment Discontinuation 
After randomization, a subject may stop treatment permanently for a variety of reasons.  
Treatment discontinuations may be initiated by a subject who is not satisfied with 
treatment or may become medically necessary due to AEs, required treatment with a 
disallowed medication or therapy, or other issues, as determined by the investigator.  
However, each investigator must comprehensively review the circumstances and offer the 
subject options for continued treatment to the degree possible as described in 
Section 3.8.3.4, Procedures to Encourage Continued Trial Participation. 
If any of the following discontinuation criteria is met and it is decided to discontinue 
treatment for a subject, examinations at the time of discontinuation specified in 
Section 3.7.1.2.11, Withdrawal (Acceptable Window:  Day of Withdrawal Judgment + 7 
Days), will be performed, and the date and reasons for discontinuation (see 
Section 3.8.3.2, Documenting Reasons for Treatment Discontinuation) will be recorded 
in the source documents and the CRF. 
1) The subject’s (or the subject’s legal representative) requests for withdrawal. 
2) Occurrence of an AE making continuation of IMP administration difficult.

3) The subject meets any of the discontinuation criteria specified in the Guidance on 
Safety Monitoring (see Appendix 4). 
4) The subject uses or it is considered that the subject needs to use any prohibited 
concomitant medication or therapy. 
5) The subject is found not to have met one or more of the inclusion criteria or to 
have fallen under any of the exclusion criteria. 
6) The subject has failed to enter headache-related information at least 75% of the 
days in the electronic headache diary between the scheduled visits. 
7) A marked deviation related to IMP administration is detected. 
8) A female subject becomes pregnant, or is suspected of being pregnant, or desires 
to become pregnant (see Section 5.6, Pregnancy). 
9) Other cases where it is considered by the investigator that the subject should 
discontinue treatment for reasons such as a difficulty in complying with the 
protocol 
 
3.8.3.2 
Documenting Reasons for Treatment Discontinuation 
Concerning each subject undergoing treatment discontinuation, the investigator will 
choose one of the following main reasons for treatment discontinuation and record it on 
the CRF.  If a subject discontinues trial treatment due to an AE, the investigator or other 
trial personnel will make every effort to follow the event until it has resolved or stabilized. 
 Withdrawal by subject  
 Withdrawal by parent/guardian 
 Adverse event 
 
Continuing IMP places the subject at undue risk as determined by the investigator 
because of the onset of an AE. 
 
The subject meets any of the discontinuation criteria specified in the Guidance for 
Safety Monitoring (see Appendix 4). 
 Protocol deviation 
 
The subject uses or it is considered that the subject needs to use any prohibited 
concomitant medication or therapy. 
 
The subject is found not to have met one or more inclusion criteria or to have 
fallen under any of the exclusion criteria. 
 
The subject has failed to enter headache-related information at least 75% of the 
days in the electronic headache diary between the scheduled visits. 
 
A marked deviation related to IMP administration is detected. 
 Pregnancy 
 Lost to follow-up 
 Lack of efficacy 
 Site terminated by sponsor

3.8.3.3 
Withdrawal of Consent 
All subjects have the right to withdraw their consent from further participation in the trial 
at any time without any disadvantage.  Subjects cannot withdraw consent for use of data 
already collected as part of the trial, but only for future participation.  The investigator 
can also discontinue a subject’s participation in the trial at any time if medically 
necessary.  Unless the subject provides their written withdrawal of consent or there is 
other written documentation by the investigator confirming the subject’s verbal intent to 
completely withdraw from the trial, subjects should be followed for all protocol-specified 
evaluations and assessments, if possible. 
Complete withdrawal of consent requires a subject’s refusal of ALL of the following 
methods of follow up (these methods of follow up will also be noted in the trial ICF): 
 Participation in all follow-up procedures specified in the protocol (whether in-clinic, 
by telephone, or by an in-home visit). 
 Participation in a subset of protocol-specified follow-up procedures (a part of follow-
up procedures for which the subject withdraws his/her permission, as agreed by 
subject and trial personnel). 
 Contact of the subject by trial personnel, even if only by telephone, to assess current 
medical condition, and obtain necessary medical or laboratory reports relevant to the 
trial’s objectives. 
 Contact of alternative person(s) who have been designated in source documents as 
being available to discuss the subject’s medical condition, even if only by telephone, 
mail, or e-mail (eg, family, spouse, partner, legal representative, friend, neighbor, or 
physician). 
 Access to medical information from alternative sources (eg, hospital/clinic medical 
records, referring doctor’s notes, public records, dialysis, transplantation or vital 
registries, social media sources). 
Withdrawal of consent is a critical trial event and therefore should be approached with 
the same degree of importance and care as is used in initially obtaining informed consent.  
The reasons for a subject’s intended withdrawal need to be completely understood, 
documented, and managed to protect the rights of the subject and the integrity of the trial.  
A subject may initially express his/her desire to discontinue IMP administration, which is 
not equivalent to a complete withdrawal of consent for further participation (see 
Section 3.8.3.1, Treatment Discontinuation).  A subject may, however, indicate that 
further trial participation is creating a burden on his/her work or social schedule.  
Therefore, the investigator should follow the procedures outlined in Section 3.8.3.2, 

Protocol 406-102-00003 
Confidential - Proprietary Information 
69 
Version 5.0, 08 Jul 2019 
 
 
(English translation, 06 Aug 2019) 
Documenting Reasons for Treatment Discontinuation to determine if the subject can 
continue participation in the trial if modifications to his/her treatment and/or schedule of 
assessments can be accommodated.  Only subjects who withdraw their permission for all 
of the above degrees of follow-up are considered to have completely withdrawn their 
consent to participate in the trial. 
3.8.3.4 
Procedures to Encourage Continued Trial Participation 
In all cases of impending IMP discontinuation or consent withdrawal, investigators will 
be given instructions to meet and discuss with the subject their options of continuing in 
the trial, preferably on therapy.  The investigator should ensure understanding and 
documentation of the reasons for the subject’s desire to withdraw consent. 
3.9 
Screen Failures 
A screen failure subject is one from whom written informed consent is obtained but who 
is not randomized in the trial. 
If the subject meets the definition of a screen failure, the following information will be 
recorded on the CRF: 
 Visit date 
 Date of informed consent 
 Date of investigation 
 Birth date 
 Sex 
 Race 
 Ethnicity 
 Country 
 Results of assessment for eligibility criteria (if the subject is found to be ineligible, 
the number of the criterion that renders the subject ineligible will be recorded.) 
 Date of assessment as a screen failure 
 Reason for screen failure 
 
3.10 
Definition of Completed Subjects 
Subjects who are evaluated at the last scheduled visit during the treatment period will be 
defined as trial completers.  For the purposes of this trial, subjects who complete 
assessments at V15/End of treatment will be defined as trial completers.

3.11 
Definition of Subjects Lost to Follow-up 
Subjects who cannot be contacted on or before V15/End of treatment during the 
treatment period, who do not have a known reason for discontinuation (eg, withdrew 
consent or AE), and for whom a survival status cannot be determined will be classified as 
“lost to follow-up” as the reason for discontinuation.  Subjects who do not return to the 
trial site for V16/Follow-up will also be defined as subjects lost to follow-up.  Survival 
status can be determined from a variety of sources, either by obtaining acceptable 
documentation for death (ie, death certificate, medical records, public records, statement 
by a family member or primary care physician) or acceptable documentation for life (ie, 
direct contact with the subject, medical records, successful telephone contact with the 
subject, statement by a family member or primary care physician, or public records). 
The trial site will make 3 documented attempts to contact the subject by telephone and in 
the event the site is unable to reach the subject by telephone, the site will attempt to 
contact the subject via certified mail or an alternative similar method, where appropriate, 
before assigning a “lost to follow-up” status. 
3.12 
Protocol Deviations 
In the event of a deviation from the protocol due to an emergency, accident, or mistake 
(eg, noncompliance with GCP guidelines, violation of IMP assignment or treatment 
compliance, violation of inclusion/exclusion criteria or discontinuation criteria, or 
violation of concomitant medication criteria), the investigator or designee will contact the 
sponsor at the earliest possible time.  The investigator and sponsor will come as quickly 
as possible to a joint decision regarding the subject’s continuation in the trial.  The 
investigator will record any protocol deviation on the source documents.  Any major

Restrictions 
Use of the following medications and concomitant therapies will be prohibited or 
restricted from after informed consent (or after V1/Screening if the date of informed 
consent and V1/Screening fall on a different day) to V15/End of treatment or the time of 
withdrawal.  Restrictions in regard to pregnancy and sexual activity are detailed in 
Section 3.4.3, Exclusion Criteria.  Male patients may not donate sperm during the trial 
and for 225 days after the final dose of IMP. 
The prohibitions and restrictions related to medications and concomitant therapies 
specified in the following sections will not apply to subjects enrolled for ADA 
assessment only.  However, these subjects will be subject to restrictions in regard to 
pregnancy and sexual activity, similarly to those who receive the IMP, for 225 days after 
the final dose of IMP in the phase 2b/3 trials (Trials 406-102-00001 and 406-102-00002). 
4.1 
Prohibited/Restricted Medications 
Subjects will be allowed to use acute headache medication only at the time of occurrence 
of a headache attack, as needed, but will not be allowed to use it as preventive medication. 
Use of other medications that belong to the same classes as those of prohibited or 
restricted medications but are not included in Table 4.1.1-1 or Table 4.1.2-1 are allowed. 
4.1.1 
Prohibited Medications (Preventive Migraine Medications) 
Use of any preventive migraine medications other than the IMP (see Table 4.1.1-1) will

Restricted Concomitant Medications (Preventive Migraine 
Medications) 
A small subgroup of subjects will be allowed to use no more than 2 concomitant 
preventive migraine medications (see Table 4.1.2-1) at a stable dose and regimen during 
the trial if the medications were previously prescribed for migraine or for another 
indication.  However, such subjects on preventive medication must be on a stable dose 
and regimen for at least 2 months of consecutive use prior to informed consent.  Subjects 
will be allowed to discontinue the use of preventive medication if discontinuation is 
considered clinically necessary by the investigator (for reasons such as they are no longer 
needed or they are associated with safety concerns).  In such a case, reasons for 
discontinuation should be recorded. 
In principle, use of medicines (including Chinese herbal medicines) or supplements that 
are regarded as effective for preventing migraine will be allowed if they were previously 
used before informed consent.  Subjects on such medicines or supplements should be on 
a stable dose and regimen in so far as possible.

Reporting of Adverse Events 
5.1 
Definitions 
An AE is defined as any untoward medical occurrence in a patient or clinical trial subject 
administered a medicinal product and which does not necessarily have a causal 
relationship with this treatment.  AEs would not include information recorded as medical 
history at screening for preplanned procedures for which the underlying condition was 
known and no worsening occurred.  An adverse reaction is any untoward and unintended 
response to an IMP related to any dose administered. 
A suspected adverse reaction is any AE for which there is a reasonable possibility that the 
IMP caused the AE. 
 
An SAE includes any event that results in any of the following outcomes. 
 Death 
 Life-threatening; ie, the subject was, in the opinion of the investigator, at immediate 
risk of death from the event as it occurred.  It does not include an event that, had it 
occurred in a more severe form, might have caused death. 
 Persistent or significant incapacity/disability or substantial disruption of the ability to 
conduct normal life functions. 
 Requires in-patient hospitalization or prolongs hospitalization. 
 
Hospitalization itself should not be reported as an SAE; whenever possible the 
reason for the hospitalization should be reported. 
 
Hospitalizations or prolonged hospitalizations for social admissions (ie, those 
required for reasons of convenience or other non-medical need) are not 
considered SAEs. 
 Congenital anomaly/birth defect. 
 Other medically significant events that, based upon appropriate medical judgment, 
may jeopardize the subject and may require medical or surgical intervention to 
prevent one of the outcomes listed above; eg, allergic bronchospasm requiring 
intensive treatment in an emergency room or home, blood dyscrasias or convulsions 
that do not result in hospitalization, or the development of drug dependency or drug 
abuse.  Any potential drug-induced liver injury (DILI) case (AST or ALT ≥ 3 × upper 
limit of normal [ULN], and total bilirubin ≥ 2 × ULN or INR > 1.5) is considered an 
SAE even if it does not require hospitalization. 
Nonserious AEs are all AEs that do not meet the criteria for a “serious” AE. 
 
An immediately reportable event (IRE) is any of the following: 
 Any SAE. 

Protocol 406-102-00003 
Confidential - Proprietary Information 
74 
Version 5.0, 08 Jul 2019 
 
 
(English translation, 06 Aug 2019) 
 Any AE experienced by investigators or other trial personnel during handling of the 
IMP 
(example:  A nurse has accidental eye contact with an injection solution, which 
causes dacryorrhea.) 
 Pregnancies are also defined as IREs.  Although normal pregnancy is not an AE, it 
will mandate IMP discontinuation and must be reported on an IRE form to the 
sponsor.  Pregnancy will only be documented on the AE CRF if there is an 
abnormality or complication. 
 Any ophthalmic AE of at least moderate severity 
 Any event of suspected anaphylaxis or severe hypersensitivity reaction 
 Any infection caused by a biological pharmaceutical/IMP that is contaminated or 
suspected of being contaminated with viruses such as HBV, HCV, and HIV.  
Seasonal infections such as the common cold are not included. 
 
Clinical Laboratory Test Value Changes:  It is the investigator’s responsibility to review 
the results of all laboratory tests as they become available.  This review will be 
documented by the investigator’s dated signature on the laboratory report.  For each 
abnormal laboratory test result, the investigator needs to ascertain if this is an abnormal 
(ie, clinically significant) change from baseline for that individual subject.  This 
determination, however, does not necessarily need to be made the first time an abnormal 
value is observed.  The investigator may repeat the laboratory test or request additional 
tests to verify the results of the original laboratory tests.  If this laboratory value is 
considered medically relevant by the investigator (subject is symptomatic, requiring 
corrective treatment or further evaluation), or if the laboratory value leads to 
discontinuation, and/or fulfills a seriousness criterion, this is considered an AE. 
 
Severity:  Adverse events will be graded on a 3-point scale and reported as indicated on 
the CRF.  The intensity of an adverse experience is defined as follows: 
1 = Mild: 
Discomfort noticed, but no disruption to daily activity. 
2 = Moderate: Discomfort sufficient to reduce or affect normal daily activity. 
3 = Severe: 
Inability to work or perform normal daily activity. 
 
IMP Causality:  Assessment of causal relationship of an AE to the use of the IMP is 
defined as follows: 
Related:  
There is a reasonable possibility of a temporal and causal relationship 
between the IMP and the AE. 
Not Related:  There is no temporal or causal relationship between the IMP and the AE.

5.2 
Eliciting and Reporting Adverse Events 
The investigator will periodically assess subjects for the occurrence of AEs.  To avoid 
bias in eliciting AEs, subjects should be asked the non-leading question:  “How have you 
felt since your last visit?”  All AEs (serious and nonserious) reported by the subject must 
be recorded on the source documents and CRFs provided by the sponsor.  Adverse events 
and SAEs are to be collected during the period from the time a subject signs the ICF to 
the end of trial date for individual subject.  Also for subjects enrolled for ADA 
assessment only, AEs will be collected during the period from the time a subject signs the 
ICF for this trial to the end of trial date for individual subject in a similar manner.  
Furthermore, any AE that has not resolved by the end date of either of the phase 2b/3 
trials (Trials 406-102-00001 and 406-102-00002) will be followed in this trial, and its 
latest outcome as of the end date of this trial is to be recorded on source documents and 
the CRF provided by the sponsor. 
Use medical terminology in AE reporting.  Adverse events should be reported as a single 
unifying diagnosis whenever possible or, in the absence of a unifying diagnosis, as 
individual signs or symptoms.  Exacerbation or disease progression should be reported as 
an AE only if there are unusual or severe clinical features that were not present, or 
experienced earlier, or not expected based on the course of the condition. 
Any reported AE for which the severity or seriousness has changed after reporting should 
be reported as a new AE on the CRF. 
In addition, the sponsor must be notified immediately by telephone, fax, or e-mail of any 
IREs according to the procedure outlined in Section 5.3, Immediately Reportable Events 
(IREs).  Special attention should be paid to recording hospitalization or concomitant 
medications. 
5.3 
Immediately Reportable Events (IREs) 
The investigator must report within 24 hours after either the investigator or designee 
becomes aware of any IRE (see Section 5.1, Definitions) by telephone, fax, or e-mail to 
the sponsor (for contact information, see the cover page of this protocol).  An IRE form 
must be completed and sent by e-mail, fax, or overnight courier to the sponsor.  (Please 
note that the IRE form is not the AE page of the CRF.)  When sending an IRE form by e-
mail, etc, sufficient care and attention must be taken to protect subject privacy. 
Subjects experiencing SAEs should be followed clinically until the events are resolved, 
stabilized, or the subject is lost to follow-up.  Resolution means that the subject has 
returned to the baseline state of health and stabilized means that the investigator does not 
expect any further improvement or worsening of the subject’s condition.  It is expected

76 
Version 5.0, 08 Jul 2019 
 
 
(English translation, 06 Aug 2019) 
that the investigator will provide or arrange appropriate supportive care for the subject 
and will provide prompt updates on the subject’s status to the sponsor. 
5.4 
Potential Drug-induced Liver Injury 
See Appendix 4 for guidance on how to monitor subjects with increased liver function 
test values.  Any potential DILI case (AST or ALT ≥ 3 × ULN and total 
bilirubin ≥ 2 × ULN or INR > 1.5) requires immediate withdrawal from the trial.  All 
values measured in accordance with the guidance on monitoring will be recorded on an 
IRE form, and the case will be recorded on the CRF as an AE. 
5.5 
Events of Suspected Anaphylaxis or Severe Hypersensitivity 
Reaction 
Severe hypersensitivity reactions will be monitored using the diagnostic clinical criteria 
for anaphylaxis as outlined by the 2006 Joint National Institute of Allergy and Infectious 
Disease/Food Allergy and Anaphylaxis Network Second Symposium on Anaphylaxis22 
(see Appendix 2).  In the event of suspected anaphylaxis, vital signs, including oxygen 
saturation and respiration rate, will be measured.  Other assessments will be performed at 
the discretion of the investigator. 
5.6 
Pregnancy 
Women of child-bearing potential (WOCBP) are defined as female subjects for whom 
menstruation has started and who are not documented as sterile (ie, have had a bilateral 
oophorectomy and/or hysterectomy or who have been postmenopausal for at least 
12 months since last menses and whose FSH level is higher than 35 U/L). 
For WOCBP and for men who are sexually active, there must be a documented 
agreement that the subject and/or their partner will take effective measures 
(ie, double-barrier method) to prevent pregnancy during the course of the trial and for 
225 days after the final dose of IMP.  Unless the subject or their partner is sterile (ie, 
women who have had a bilateral oophorectomy and/or hysterectomy or who have been 
postmenopausal for at least 12 consecutive months since last menses and whose FSH 
level is higher than 35 U/L; or men who have had a bilateral orchidectomy) or remains 
abstinent, 2 of the following precautions must be used:  vasectomy, tubal ligation, vaginal 
diaphragm, intrauterine device, birth control pills, birth control depot injection, birth 
control implant, condom with spermicide, or sponge with spermicide.  Any single method 
of birth control, including vasectomy and tubal ligation, may fail, leading to pregnancy.  
The contraceptive method will be documented at each trial visit.

(English translation, 06 Aug 2019) 
Before enrolling WOCBP in this clinical trial, investigators must review the below 
guidelines about trial participation with all WOCBP.  The topics should generally 
include: 
 General information 
 ICF 
 Pregnancy prevention information 
 Drug interactions with hormonal contraceptives 
 Contraceptives in current use 
 Guidelines for the follow-up of a reported pregnancy 
 
Before trial enrollment, WOCBP must be advised of the importance of avoiding 
pregnancy during trial participation and the potential risk factors for an unintentional 
pregnancy.  The subject must sign an ICF stating that the above-mentioned risk factors 
and the consequences were discussed with her. 
A serum HCG test will be performed at V1/Screening on all WOCBP. 
During the trial, all WOCBP should be instructed to contact the investigator immediately 
if they suspect they might be pregnant (eg, missed or late menstrual cycle). 
If a subject is suspected to be pregnant before she receives IMP, the IMP administration 
must be withheld until the results of serum HCG tests are available.  If the pregnancy is 
confirmed, the subject must not receive the IMP and must not be enrolled in the trial.  If 
pregnancy is suspected while the subject is taking IMP, the IMP must be withheld 
immediately (if reasonable, taking into consideration any potential withdrawal risks) until 
the result of the serum HCG is known.  If pregnancy is confirmed, the IMP will be 
permanently discontinued in an appropriate manner (eg, dose tapering if necessary for 
subject safety) and the subject will be withdrawn from the trial. 
The investigator must immediately notify the sponsor of any pregnancy associated with 
IMP exposure during the trial and for 225 days after the final dose of IMP, and record the 
event on the IRE form and forward it to the sponsor.  The sponsor will forward Clinical 
Trial Pregnancy and Breastfeeding Exposure Form for monitoring the outcome of the 
pregnancy (including spontaneous or elective abortion). 
Protocol-required procedures for trial discontinuation and follow-up must be performed 
on the subject unless contraindicated by pregnancy (eg, x-ray studies).  Other appropriate 
pregnancy follow-up procedures should be considered, if indicated.  In addition, the 
investigator must report to the sponsor, on appropriate Clinical Trial Pregnancy and 
Breastfeeding Exposure Form, follow-up information regarding the course of the

Follow-up of Adverse Events 
For this trial, information on AEs will be collected for the period from the time the 
subject signs the informed consent form until the end of trial date for individual subject 
(the last scheduled contact).  Even after the end of trial date for individual subject, AEs 
that meet any of the cases described in Section 5.8.1, Follow-up of Nonserious Adverse 
Events, through Section 5.8.3, Follow-up and Reporting of Serious Adverse Events 
Occurring After End of Trial Date for Individual Subject (Last Scheduled Contact, will 
be followed as specified in the relevant section. 
5.8.1 
Follow-up of Nonserious Adverse Events 
Nonserious AEs that are identified at any time during the trial must be recorded on the 
AE CRF with the current status noted.  If a subject has an AE whose causal relationship 
with the IMP cannot be ruled out or has not recovered from an AE at the end of trial date 
for individual subject (the last scheduled contact), follow-up contacts will be performed 
until the event is resolved, stabilized, or the subject is lost to follow-up.  All nonserious 
events that are ongoing at the end of trial date for individual subject (the last scheduled 
contact) will be recorded as ongoing on the CRF and follow-up information obtained 
after the end of trial date for individual subject (the last scheduled contact) will be 
recorded in the subject’s medical record.  For any AE having been identified throughout 
the trial, during analysis, additional relevant medical history information may be 
requested to further ascertain causality (including, but not limited to, information such as 
risk-related behavior, family history and occupation). 
5.8.2 
Follow-up of Serious Adverse Events 
This trial requires that subjects be actively monitored for SAEs for the period from the 
time of the subject’s signing the ICF until the end of trial date for individual subject (the 
last scheduled contact). 
Serious AEs that are identified or ongoing at the end of trial date for individual subject 
(the last scheduled contact) must be recorded on the AE CRF page and reported to the 
sponsor according to the reporting procedures outlined in Section 5.3, Immediately 
Reportable Events (IREs).  This may include unresolved previously reported SAEs, or 
new SAEs.  Any SAE that is ongoing at the end of trial date for individual subject (the

last scheduled contact) is recorded as ongoing on the CRF.  The investigator will follow 
SAEs until the events are resolved, stabilized, or the subject is lost to follow-up.  The 
investigator will continue to report any significant follow-up information to the sponsor 
up to the point the event is resolved, stabilized, or the subject is lost to follow-up using an 
IRE form. 
5.8.3 
Follow-up and Reporting of Serious Adverse Events Occurring 
After End of Trial Date for Individual Subject (Last Scheduled 
Contact) 
Any new SAEs reported by the subject to the investigator that occur after the end of trial 
date for individual subject (the last scheduled contact), and are determined by the 
investigator to be reasonably associated with the use of the IMP, should be reported to the 
sponsor.  This may include SAEs that are captured on follow-up telephone contact or at 
any other time point after the defined trial period (ie, up to end date of the period of trial 
participation [the end of trial date for individual subject]).  The investigator should follow 
SAEs identified after the end of trial date for individual subject (the last scheduled 
contact) until the events are resolved, stabilized, or the subject is lost to follow-up.  The 
investigator should continue to report any significant follow-up information to the 
sponsor up to the point the event has been resolved or stabilized, or the subject is lost to 
follow-up using an IRE form.

Statistical Analysis 
7.1 
Sample Size 
Sample size was not calculated by any statistical method. 
In order to fully evaluate the long-term safety of TEV-48125 in Japanese patients, it is 
necessary to collect data from 100 Japanese patients who have completed a 1-year 
treatment with the drug at the same doses and regimens as those in the phase 2b/3 trials 
(Trials 406-102-00001 and 406-102-00002) conducted in parallel with this trial (see 
Section 2.1, Trial Rationale).  Assuming a 30% discontinuation rate in Japanese subjects 
in a multinational phase 3 long-term trial (Trial TV48125-CNS-30051), approximately 80 
patients receiving TEV-48125 are expected to complete the multinational phase 3 
confirmatory trials (Trials TV48125-CNS-30049 and TV48125-CNS-30050).  To make 
up the difference (20 patients), assuming the same discontinuation rate of 30% in this 
trial (Trial 406-102-00003), it is estimated that 30 patients are needed.  Considering the 
possibility that the discontinuation rate may exceed 30% in either the multinational phase 
3 long-term trial or this trial, in order to ensure compliance with the criteria contained in 
the ICH E1 Guideline that 100 subjects complete a year of administration, it is considered 
necessary to enroll 40 new patients in this trial. 
 
For the purpose of ADA assessment, up to 966 subjects who have completed or 
discontinued either of the phase 2b/3 trials (Trials 406-102-00001 and 406-102-00002) in 
patients with CM or EM will be enrolled in this trial.  Of these subjects, only those who 
have received TEV-48125 in either of the phase 2b/3 trials (Trials 406-102-00001 and 
406-102-00002) will be evaluated for ADAs in this trial.  Therefore, ADA assessment 
will be performed in approximately 644 subjects (approximately 360 subjects and 284 
subjects who have received TEV-48125 in Trial 406-102-00001 and Trial 406-102-00002, 
respectively).

Records Management 
9.1 
Source Documents 
Source documents are defined as the results of original observations and activities of a 
clinical investigation.  Source documents will include but are not limited to medical 
records, electronic data, screening logs, recorded data from automated instruments, 
electronic headache diary, and ePRO.  All source documents pertaining to this trial will 
be maintained by the principal investigators and made available for direct inspection by 
authorized persons.  Principal investigators/trial sites will permit trial-related monitoring, 
audits, IRB/IEC/EC review, and regulatory inspection(s) by providing direct access to 
source data/documents by authorized persons as defined in the ICF.  In all cases, subject 
confidentiality must be maintained in accordance with local regulatory requirements. 
9.2 
Data Collection 
During each subject’s visit to the trial site, the investigator will record all significant 
observations and findings in the subject’s medical records.  At a minimum, these notes 
will contain: 
 Documentation of the informed consent process, including any revised consents; 

Protocol 406-102-00003 
Confidential - Proprietary Information 
87 
Version 5.0, 08 Jul 2019 
 
 
(English translation, 06 Aug 2019) 
 Documentation of the investigator’s decision to enroll the subject into the trial, the 
review of all inclusion/exclusion criteria prior to IMP administration, and 
confirmation of the subject’s actual participation in the trial; 
 The date of the visit and the corresponding Visit or Day in the trial schedule; 
 General subject status remarks, including any significant medical findings.  The 
severity, frequency, duration, action taken, and outcome of any AEs and the 
investigator’s assessment of relationship to IMP must also be recorded; 
 Any changes in concomitant medications or dosages; 
 A general reference to the procedures completed; 
 The signature (or initials) and date of each investigator (or designee) who made an 
entry in the medical records. 
In addition, any contact with the subject via telephone or other means that provides 
significant clinical information will also be documented in the medical records as 
described above.  Any changes to information in the medical records and other source 
documents will be initialed and dated on the day the change is made by a trial site staff 
member authorized to make the change.  Changes will be made by striking a single line 
through erroneous data (so as not to obliterate the original data), and clearly entering the 
correct data (eg, wrong data  right data).  If the reason for the change is not apparent, a 
brief explanation for the change will be written in the source documents by the 
investigator.  If electronic data systems are being utilized, a full audit trail of changes 
must be maintained. 
Information from the medical records and other source documents will be entered by trial 
site staff directly onto electronic CRFs in the sponsor’s electronic data capture (EDC) 
system.  Changes to the data will be captured by an automatic audit trail.  If data are 
processed from other sources (eg, central laboratory, bioanalytical laboratory, electronic 
headache diary, and ePRO), the results will be sent to the trial site where they will be 
retained, but not entered into the EDC unless otherwise noted in the protocol.  These data 
will also be sent electronically to the sponsor from each source.  Changes to the data will 
be captured by an automatic audit trail in the source system. 
9.3 
File Management at the Trial Site 
The principal investigator will ensure that the trial site file is maintained in accordance 
with Section 8 of the ICH GCP Guideline E6 and as required by applicable local 
regulations.  The principal investigator/trial site will take measures to prevent accidental 
or premature destruction of these documents.

Records Retention at the Trial Site 
Regulatory requirements for the archival of records for this trial necessitate that 
participating principal investigators maintain detailed clinical data for the longest of the 
following 4 periods: 
 A period of at least 2 years after the date on which approval to market the drug is 
obtained (or if IMP development is discontinued, the date regulatory authorities were 
notified of discontinuation); OR 
 A period of at least 3 years after the sponsor notifies the principal investigator that the 
final report has been filed with regulatory authorities. 
 Longer, region-specific storage requirements, if applicable. 
If regional requirements are longer, the specific information for the region should be 
stated in the trial’s Operations Manual or the principal investigator’s contract. 
 Determination of the period until the termination of DNA storage or biomarker 
sample storage. 
The principal investigator must not dispose of any records relevant to this trial without 
either 1) written permission from the sponsor or 2) provision of an opportunity for 
sponsor to collect such records.  The principal investigator will be responsible to maintain 
adequate and accurate electronic or hard copy source documents of all observations and 
data generated during this trial including any data clarification forms received from the 
sponsor.  Such documentation is subject to inspection by the sponsor and relevant 
regulatory authorities.  If the principal investigator withdraws from the trial (eg, due to 
relocation or retirement), all trial-related records should be transferred to a mutually 
agreed-upon designee within a sponsor-specified timeframe.  Notice of such transfer will 
be given to the sponsor in writing. 
10 
Quality Control and Quality Assurance 
10.1 
Monitoring 
The sponsor has ethical, legal, and scientific obligations to follow this trial in accordance 
with established research principles, the ICH E6 GCP:  Consolidated Guidance, and 
applicable regulatory requirements and local laws.  As part of a concerted effort to fulfill 
these obligations (maintain current personal knowledge of the progress of the trial), the 
sponsor’s monitors will visit the trial site during the trial, as well as communicate 
frequently via telephone, e-mail, and written communications.  In addition, all 
investigators and trial site staff will undergo initial and ongoing training for this 
particular trial, and this training will be clearly documented.

(English translation, 06 Aug 2019) 
10.2 
Auditing 
The sponsor’s Quality Assurance Unit (or representative) may conduct trial site audits.  
Audits will include, but are not limited to, IMP supply, presence of required documents, 
the informed consent process, and comparison of CRFs with source documents.  The 
principal investigator agrees to cooperate with audits. 
Regulatory authorities may inspect the trial site during or after the trial.  The principal 
investigator will cooperate with such inspections and will contact the sponsor 
immediately if such an inspection occurs. 
11 
Ethics and Responsibility 
This trial must be conducted in compliance with the protocol, ICH GCP Guideline (E6), 
international ethical principles derived from the Declaration of Helsinki and Council for 
International Organizations of Medical Science (CIOMS) guidelines, and applicable local 
laws and regulations.  Each trial site will seek approval/favorable opinion by an 
IRB/IEC/EC according to regional requirements, and the principal investigator will 
provide that documentation to the sponsor.  The IRB/IEC/EC will evaluate the ethical, 
scientific, and medical appropriateness of the trial.  Further, in preparing and handling 
CRFs, IRE forms, etc, the investigator and their staff will take measures to ensure 
adequate care in protecting subject privacy.  To this end, a subject number and subject 
identification code will be used to identify each subject. 
Financial aspects, subject insurance and the publication policy for the trial will be 
documented in the agreement between the sponsor and the principal investigator. 
12 
Confidentiality 
All information generated in this trial will be considered confidential and will not be 
disclosed to anyone not directly concerned with the trial without the sponsor’s prior 
written permission.  Subject confidentiality requirements of the region(s) where the trial 
is conducted will be met.  However, authorized regulatory officials and sponsor personnel 
(or their representatives) may be allowed full access to inspect and copy the records, 
consistent with local requirements.  All IMPs, subject bodily fluids, and/or other 
materials collected shall be used solely in accordance with this protocol, unless otherwise 
agreed to in writing by the sponsor. 
Subjects will be identified only by unique subject numbers in CRFs.  If further subject 
identification is required, subjects’ full names may be made known to a regulatory 
agency or other authorized officials if necessary, subject to local regulations.

Amendment Policy 
The principal investigator will not make any changes to this protocol without the 
sponsor’s prior written consent and subsequent approval/favorable opinion by the 
IRB/IEC/EC.  Any permanent change to the protocol, whether an overall change or a 
change for specific trial site(s), must be handled as a protocol amendment.  Any 
amendment will be written by the sponsor.  Each amendment will be submitted to the 
IRB/IEC/EC, as required by local regulations.  Except for “administrative” or “non-
substantial” amendments, investigators will wait for IRB/IEC/EC approval/favorable 
opinion of the amended protocol before implementing the change(s).  Administrative 
amendments are defined as having no effect on the safety of subjects, conduct or 
management of the trial, trial design, or the quality or safety of IMP(s) used in the trial.  
A protocol change intended to eliminate an apparent immediate hazard to subjects should 
be implemented immediately after agreement by the sponsor and principal investigator, 
followed by IRB/IEC/EC notification within local applicable timelines.  The sponsor will 
submit protocol amendments to the applicable regulatory agencies within local applicable 
timelines. 
When the IRB/IEC/EC, principal investigators, and/or the sponsor conclude that the 
protocol amendment substantially alters the trial design and/or increases the potential risk 
to the subject, the currently approved written ICF will require similar modification.  In 
such cases, after approval/favorable opinion of the new ICF by the IRB/IEC/EC, repeat 
written informed consent will be obtained from subjects enrolled in the trial before 
expecting continued participation and before the amendment-specified changes in the 
trial are implemented. 
14 
Publication Authorship Requirements 
Authorship for any Otsuka-sponsored publications resulting from the conduct of this trial 
will be based on International Committee of Medical Journal Editors (ICMJE) authorship 
criteria (http://www.icmje.org/recommendations).  According to ICMJE guidelines, one 
may be considered an author only if the following criteria are met: 
1) Substantial contributions to the conception or design of the work; or the 
acquisition, analysis, or interpretation of data for the work; AND 
2) Drafting the work or revising it critically for important intellectual content; AND 
3) Final approval of the version to be published; AND 
4) Agreement to be accountable for all aspects of the work in ensuring that questions 
related to the accuracy or integrity of any part of the work are appropriately 
investigated and resolved.

Appendix 1 
Handling and Shipment of Bioanalytical Samples 
(1) 
Handling of Samples 
A label will be firmly attached to each sample storage tube.  The label contains the 
following information:  protocol number, subject identification number, visit number (eg, 
V2/Baseline, V3/Month 3), sampling date, sampling timing (eg, before administration), 
sample type (eg, pharmacokinetics, ADA, DNA, or serum for biomarkers), and aliquot 
number (eg, Aliquot 1, Aliquot 2).  Instead of the planned sampling time point, the time 
at which specimens were actually sampled should be accurately entered on the case 
report form. 
(2) 
Handling and Shipment of Pharmacokinetic Samples 
Six milliliters of blood will be collected via venipuncture or indwelling catheter into a 
dipotassium ethylenediaminetetraacetic acid (EDTA) collection tube.  Then, the 
collection tube will be inverted slowly 8 to 10 times to mix the content and will be placed 
in ice water.  This sample will be centrifuged (approximately 1300 × G) at approximately 
4ºC for approximately 10 minutes between 5 minutes and 1 hour after blood collection.  
If a refrigerated centrifuge is not available, samples should be chilled before 
centrifugation.  Plasma will be aliquoted by a standard experimental procedure into 2 
appropriately labeled tubes for storage (Aliquot 1 and 2).  The 2 aliquots of the same 
plasma sample will be stored in a freezer at a temperature of below −20ºC or −70ºC 
within 60 minutes of the end of centrifugation.  Within 3 days after sampling, the central 
laboratory will collect plasma sample Aliquots 1 and 2 and store them in a freezer at a 
temperature of below −70ºC.  During transfer, all samples will be placed in a well-
insulated container filled with a sufficient amount of dry ice.  The central laboratory will 
transport Aliquot 1 plasma samples to the drug concentration measurement facility in 
accordance with instructions of the sponsor.  The central laboratory will store Aliquot 2 
plasma samples until the clinical study report is issued unless otherwise instructed by the 
sponsor. 
(3) 
Handling and Shipment of ADA Samples 
Blood will be collected via venipuncture or indwelling catheter into a collection tube 
containing no anticoagulant (containing a coagulation accelerator, 5 mL).  Blood 
collected will be left to stand at room temperature for approximately 30 minutes to allow 
for coagulation and serum separation to occur.  The sample will then be centrifuged 
(approximately 1300 × G) at approximately 4ºC for approximately 10 minutes within 
1.5 hours of sampling.  If a refrigerated centrifuge is not available, samples should be 
chilled before centrifugation.  Serum will be aliquoted by a standard experimental 
procedure into 2 appropriately labeled tubes for storage (Aliquot 1 and 2).  The 2 aliquots 
of the same serum sample will be stored in a freezer at a temperature of below −20ºC or

−70ºC within 60 minutes of the end of centrifugation.  Within 3 days after sampling, the 
central laboratory will collect serum sample Aliquots 1 and 2 and store them in a freezer 
at a temperature of below −70ºC.  During transfer, all samples will be placed in a well-
insulated container filled with a sufficient amount of dry ice.  The central laboratory will 
transport Aliquot 1 serum samples to the ADA measurement facility in accordance with 
instructions of the sponsor.  The central laboratory will store Aliquot 2 serum samples 
until the clinical study report is issued unless otherwise instructed by the sponsor. 
(4) 
Handling and Shipment of DNA Samples 
Six milliliters of blood will be collected via venipuncture or indwelling catheter into a 
dipotassium EDTA collection tube.  Then, the collection tube will be inverted slowly 8 to 
10 times to mix the contents.  The blood sample will be transferred into an appropriately 
labeled tube for storage.  The blood sample will be stored in a freezer at a temperature of 
below −20ºC or −70ºC within 60 minutes of sampling.  Within 3 days after sampling, the 
central laboratory will collect blood samples and store them in a freezer at a temperature 
of below −70ºC.  During transfer, all samples will be placed in a well-insulated container 
filled with a sufficient amount of dry ice.  The central laboratory will assign a new 
personal code to each sample to make it double-coded.  Then, DNA will be extracted 
from these samples.  DNA samples will be stored in a freezer at a temperature of below 
−70ºC. 
(5) 
Handling and Shipment of Serum Samples for Biomarkers 
Blood will be collected via venipuncture or indwelling catheter into a collection tube 
containing no anticoagulant (containing a coagulation accelerator, 6 mL).  Blood 
collected will be left to stand at room temperature for approximately 30 minutes to allow 
for coagulation and serum separation to occur.  The sample will then be centrifuged 
(approximately 1300 × G) at approximately 4ºC for approximately 10 minutes within 1.5 
hours of sampling.  If a refrigerated centrifuge is not available, samples should be chilled 
before centrifugation.  Serum will be transferred by a standard experimental procedure 
into an appropriately labeled tube for storage.  The serum sample will be stored in a

Guidance on Safety Monitoring 
 
Guidance on Monitoring Patients With Elevated Liver Function Tests 
Liver enzymes (ALT, AST, GGT, and ALP) as well as total bilirubin and direct bilirubin 
will be measured (and indirect bilirubin will be calculated) at each trial visit. 
In any case of elevated ALT or AST to a level exceeding ≥ 2× the ULN (including 
patients whose baseline ALT or AST levels are ≥ 2 × and ≤ 3 × the ULN, who may be 
enrolled in the trial), a thorough medical history should be taken and a physical 
examination with a focus on liver disease should be performed.1  In addition, the patient 
should be instructed to refrain from alcoholic beverages. 
In cases where the symptoms are compatible with drug-induced liver injury during the 
trial, patients will be instructed to return to the trial site for an unscheduled visit to 
measure liver enzymes as soon as possible.  Solitary elevations of total or direct bilirubin, 
not accompanied by elevations of ALT or AST, should be managed based on the 
judgement of the treating physician. 
In line with Section 3.7.3.2, Clinical Laboratory Assessments, all blood testing will be 
performed at the central laboratory.  The day on which the abnormal value is received 
from the central laboratory will be considered as Day 0. 
 
Elevation of Either ALT or AST to ≥ 3× ULN 
Confirmation is required prior to investigational medicinal product (IMP) discontinuation 
in cases of elevation of either ALT or AST ≥ 3× ULN (Note:  In cases of elevation of 
ALT or AST ≥ 8× the ULN, no confirmation is required prior to IMP discontinuation, but 
the assessments below should be performed).  The following procedures should be 
followed: 
 The investigator should repeat the test for confirmation purposes [ALT, AST, ALP, 
total and direct bilirubin, complete blood count (CBC) (with differential for 
                                                 
1 Thorough medical history with a focus on liver disease:  personal or family history of liver 
disease; personal history of a systemic disease with potential liver involvement; exposure to 
alcohol, medications (prescription or over-the-counter), herbal preparations, dietary 
supplements, recreational drugs, special diets, or environmental chemical agents; potential 
exposure to infectious agents (eg, travel to developing countries, history of potential exposure 
to blood or blood products, high-risk sexual relations); and any additional information deemed 
relevant by the principal investigator.  Physical examination, including signs of chronic liver 
disease.

eosinophil count), and INR].  The investigator should also question the patient 
regarding symptoms. 
The abnormality will be regarded as confirmed in each of the following scenarios: 
 The baseline value was within the normal range and ALT or AST is still ≥ 3 × the 
ULN. 
 The baseline value was above the ULN and ALT or AST is ≥ 2 × the baseline value. 
 
Additional Tests/Evaluations: 
Upon confirmation of the abnormality as noted above, the following additional 
evaluations should be performed 
 Serology for hepatitis A (antibody and immunoglobulin M [IgM] and IgG), B (core 
antibody total, core IgM, and surface antigen), and C (antibody) viruses  
 Serology for autoimmune hepatitis:  antinuclear antibodies (titer), antismooth muscle 
antibodies, and antiliver kidney microsomal antibodies 
 Ultrasound examination of the liver and biliary tract at the investigator’s discretion 
(date of examination and the normality/abnormality judgment will be recorded in 
CRF)  
 Observation and follow-up (to be performed after the abnormality was confirmed as 
above) 
 
ALT or AST ≥ 3 × (> 3.5 × the ULN if the Baseline Value Is > 2.5 × the ULN) but 
Less Than 5 × the ULN 
In addition to the above procedures required for any elevation to levels > 3 × the ULN: 
 ALT, AST, GGT, ALP, total and direct bilirubin, CBC (including differential), and 
INR should be monitored on Days 5 (± 2 days), 8 (± 2 days), 14 (± 3 days), and 28 
(± 3 days). 
 Should the abnormality (≥ 3 × the ULN in cases where the baseline value was within 
the normal range or ≥ 2 × the ULN in cases where the baseline value was above ULN 
but still < 5 × the ULN) persist, the patient will be followed at the investigator’s 
discretion, but ALT, AST, GGT, ALP, and total and direct bilirubin should be 
monitored. 
 
ALT or AST ≥ 5 × but Less Than 8 × the ULN 
In addition to the above procedures required for any elevation to levels > 3 × the ULN: 
 ALT, AST, GGT, ALP, total and direct bilirubin, CBC (including differential), and 
INR should be monitored twice a week.

ALT or AST ≥ 8 × the ULN 
In addition to the above procedures required for any elevation to levels > 3 × the ULN: 
 The IMP should be discontinued immediately, and the early withdrawal visit should 
be performed. 
 For follow-up guidance, please see section below “Follow-up of Liver Enzymes After 
Stopping Rules Are Met.” 
 
Stopping Rules 
In the following circumstances, the IMP will be discontinued immediately: 
 Any increase in ALT or AST to ≥ 3 × the ULN, combined with INR > 1.5 × the ULN 
or total bilirubin > 2 × the ULN 
 Any increase in ALT or AST to ≥ 3 × the ULN, which is accompanied by symptoms 
clearly associated with impaired liver function (eg, vomiting, nausea, fever, rash, 
eosinophilia) and not deemed related to other diseases (eg, vomiting or nausea 
triggered by migraine) 
 Any increase in ALT or AST to levels ≥ 5 but < 8 × the ULN, which is persistent for 
≥ 2 weeks of repeated measurements 
 Any increase in ALT or AST to levels ≥ 8 × the ULN 
 In any case where monitoring of liver enzymes cannot be performed according to the 
protocol guidance 
 
Follow-up of Liver Enzymes After Stopping Rules Are Met 
 A patient who meets the above criteria for discontinuation of the IMP should be 
invited to the trial site to return the IMP.  Withdrawal visit activities should be 
performed as soon as possible. 
 Liver enzymes should be monitored until normalization or stabilization of the 
abnormality, based on the judgment of the investigator. 
 In any case, following the withdrawal visit, the minimal follow-up period will be 30 
days and will include measurement of liver enzymes at least once weekly. 
Every effort should be made to complete the additional tests/evaluations, as described 
above.
