CLINICAL STUDY PROTOCOL SYNOPSIS
Study TV48125-CNS-30050
Title of Study: A Multicenter, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study Comparing 
the Efficacy and Safety of 2 Dose Regimens of Subcutaneous Administration of TEV-48125 Versus Placebo for the 
Preventive Treatment of Episodic Migraine
Sponsor: Teva Branded Pharmaceutical Products R&D, Inc.
IND Number: 106,533
EudraCT Number: 2015-004598-34
Name of Active Ingredient: Humanized anti-calcitonin gene-related peptide (CGRP) monoclonal antibody
Name of Investigational Product: TEV-48125
Phase of Clinical Development: 3
Number of Investigational Centers Planned: Approximately 140
Countries Planned: Approximately 15
Planned Study Period: 1Q/2016 (first patient in) to 3Q/2017 (last patient last visit)
Number of Patients Planned: A total of 768 patients (256 patients per treatment group) are planned to be enrolled
in this study to have 675 completers (225 completers per treatment group); a 12% drop-out rate is anticipated. 
Patients will be randomized 1:1:1 to the following treatment groups:

monthly subcutaneous (sc) administration of TEV-48125 at 225 mg

sc administration of TEV-48125 at 675 mg followed by monthly sc placebo

monthly sc administration of placebo
(Note: For this study, monthly dosing refers to dosing approximately every 4 weeks [28 days].)
Study Population: The study population will be composed of female and male patients, aged 18 to 70 years,
inclusive, with a history of migraine (as defined by International Classification of Headache Disorders, 3rd revision 
[ICHD-3] criteria [Classification Committee of the IHS, 2013]) for at least 12 months prior to screening and 
episodic migraine (EM) prospectively documented via a review of headache data recorded daily in an electronic 
daily headache diary device during a 28-day run-in period.
Because headache consortium guidelines recommend preventive therapies for patients with EM occurring on 4 or 
more days per month due to the frequency of headaches and high degree of disability, patients using no more than 
1 preventive medication at the time of study enrollment will be allowed to remain on the medication if the 
medication has at least moderate evidence of efficacy for migraine (Silberstein et al 2012). Patients on concomitant 
preventive medications must be on a stable dose for at least 2 months of consecutive use prior to study entry (ie, 
before the run-in period), without anticipated changes during the study. A list of preventive medications is presented 
in Appendix A. The total number of patients receiving concomitant preventive medication during the study will not 
exceed 30% of the total sample size of the study. This subset will be randomized independently.

General Design and Methodology: This is a 16-week, multicenter, randomized, double-blind, placebo-controlled, 
parallel-group study to compare the safety, tolerability, and efficacy of 2 dose regimens of sc TEV-48125 and
placebo. 

monthly sc administration of TEV-48125 at 225 mg

sc administration of 675 mg of TEV-48125 at visit 2 followed by monthly sc placebo 

monthly sc administration of placebo 
Randomization will be performed using electronic interactive response technology (IRT). Patients will be stratified 
based on gender, country, and baseline preventive migraine medication use (yes, no) to ensure balance for the 
covariates (treatment group, preventive medication use, country, and gender).
Blinded treatment will be administered sc once monthly (approximately every 4 weeks) for a total of 3 doses. First
treatment administration will occur at visit 2 (day 0), and additional doses will be administered at visits 3 and 4. 
Final study assessments will be performed at visit 5 (end-of-treatment [EOT] visit), approximately 4 weeks after 
administration of the 3rd and final dose of study drug. Upon completion of the final study assessments, patients may 
enter a long-term safety and efficacy study (Study TV48125-CNS-30051), consisting of a 12-month double-blind 
treatment period and a 6.5-month follow-up period. In the long-term safety extension study, patients receiving active 
study drug in the current study will continue receiving the same treatment (ie, monthly sc TEV-48125 at 225 mg or 
quarterly sc TEV-48125 at 675 mg), and patients receiving placebo in the current study will be randomized in a 1:1 
ratio to receive monthly sc TEV-48125 at 225 mg or quarterly sc TEV-48125 at 675 mg during the long-term safety 
and efficacy study. Patients who do not enroll in the long-term safety and efficacy study for any reason will be 
offered to enter the long-term safety extension for the purpose of evaluating ADA approximately 7.5 months
(225 days[the approximate equivalent of 5 half-lives]) after receiving the last dose of study drug in this study.
Method of Blinding and Randomization: The sponsor, investigators, study staff (except for staff involved in 
bioanalytical analyses), and patients will be blinded to treatment assignment. A computer-generated master

randomization list will be provided to drug packaging facilities. Packaging vendor(s) will package active and 
placebo into single-visit kits according to Good Manufacturing Practice procedures. Kits will be identical in 
appearance and contain 1 prefilled syringe with active drug or placebo. Adequate kit supply for upcoming study 
visits will be managed by IRT and kept (refrigerated at 2°C to 8°C) on site.
This is a randomized study with stratification based on gender, country, and baseline preventive medication use (yes, 
no). Each patient will undergo randomization in a 1:1:1 ratio within the stratum to which he or she belongs to 
receive 1 of the 2 TEV-48125 dose regimens or placebo, as assigned by the IRT. The IRT will manage initial drug 
supply, maintenance of adequate study drug supplies on site, and study randomization centrally. At the time of each 
study visit, the IRT will be queried, and site personnel will retrieve and administer a 1.5-mL volume from each
syringe contained in the appropriately numbered kit(s).
The total number of patients receiving concomitant preventive medication during the study will not exceed 30% of 
the total sample size of the study.
Study Drug Dose, Mode of Administration, and Administration Rate: Prefilled syringes (active or placebo) will 
be contained in uniquely numbered kits and stored (refrigerated at 2°C to 8°C) on site. Active syringes will contain 
150 mg/mL of TEV-48125, and placebo syringes will contain the same vehicle and excipients as those for active 
injections. Each kit will contain 1 prefilled syringe.
Study drug will be administered by qualified study personnel as sc injections approximately every 4 weeks (28 days)
for a total of 3 doses, as follows:

Patients randomized to receive TEV-48125 at 225 mg will receive 225 mg of TEV-48125 as 1 active 
injection (225 mg/1.5 mL) and two 1.5-mL placebo injections at visit 2 and 225 mg of TEV-48125 as 
1 active injection (225 mg/1.5 mL) at visits 3 and 4.

Patients randomized to receive TEV-48125 675 mg/placebo will receive 675 mg of TEV-48125 as 
3 active injections (225 mg/1.5 mL) at visit 2 and placebo as single 1.5-mL injection at visits 3 and 4.

Patients randomized to receive placebo will receive three 1.5-mL placebo injections at visit 2 and 
single 1.5-mL placebo injection at visits 3 and 4.
The recommended sc injection sites follow the National Institutes of Health Patient Education Guidelines of 
June 2012, which are available in Appendix C and at http://www.cc.nih.gov/ccc/patient_education/pepubs/subq.pdf. 
The suggested sites of injection are back of upper arms, lower abdomen/belly/waistline, and front of thighs. Each of 
the injections at visit 2 should be given in a different location (eg, not in precisely the same place), and study staff 
member(s) responsible for administration of injections should inspect previous injection sites to ensure that they are 
free of bruising and tenderness and that proper rotation of sites is performed.
The total number of sc injections and their locations will be recorded for each dosing visit (visits 2, 3, and 4). A 
1.5-mL volume from each syringe in each visit’s kit(s) must be injected sc for dosing to be considered complete.
Investigational Product: TEV-48125
Reference Therapy: 
Placebo: Same vehicle and excipients as those for active injection
Comparison Drug: Not applicable
Duration of Patient Participation: Patient participation will last for approximately 4 months (including a 28-day 
run-in period and a 12-week, double-blind treatment period); after which, patients may enter into a double-blind, 
long-term safety and efficacy study. Patients who do not enroll in the double-blind, long-term safety and efficacy 
study for any reason will be offered to enter the long-term safety extension for the purpose of evaluating ADA

Measures and Time Points:
Primary Efficacy Measure and Time Point: The primary efficacy endpoint for this study will be derived from 
headache data (ie, occurrence of headache, duration of headache, maximum severity of headache, and acute
migraine-specific medication use) collected daily using an electronic headache diary device.
Eligible patients will receive training on the use of the electronic headache diary device and will be informed of 
compliance requirements at screening. Patients will complete electronic headache diary entries with questions 
about the previous day daily, beginning on day –27 (the day after the screening visit) through the EOT/early 
withdrawal visit. The electronic headache diary device will allow entry of headache information for up to 
48 hours after a given day.
Secondary Efficacy Measures and Time Points: Secondary efficacy endpoints will be derived from headache 
data (ie, occurrence of headache, duration of headache, maximum severity of headache, and acute

Immunogenicity Measures and Time Points: Blood samples for immunogenicity will be collected at the time 
points specified in Table 1.
Biomarker Measures and Time Points: Biomarker blood and urine samples will be collected from all patients at 
the time points specified in Table 1, and a blood sample will be collected from patients who consent to 
pharmacogenomic analysis at visit 2 or any visit thereafter.
Allowed and Disallowed Medications Before and During the Study:
Prior Medications and Therapeutic Failures of Migraine Preventives: Details regarding excluded prior migraine 
preventive treatments and therapeutic failures of migraine preventives are described in the exclusion criteria.
Concomitant (Current) Therapy: Up to 30% of patients will be allowed to remain on stable doses of no more than 
1 preventive migraine medication for the duration of the study provided the medication has at least moderate 
evidence of efficacy as defined by guidelines (Silberstein et al 2012) and presented in Appendix A. Patients on 
preventive medication must be on a stable dose for at least 2 months of consecutive use prior to study entry. 
Alternatively, patients must have discontinued the preventive medication at least 5 half-lives prior to screening.
Patients will be allowed to use acute medications to treat acute migraine attacks as needed.
All concomitant medications taken during the study must be recorded with indication, daily dose, and start and stop 
dates of administration. All patients will be questioned about concomitant medication at each clinic visit.
Statistical Considerations:
Sample Size Rationale: A sample size of 675 randomized (ie, 225 evaluable patients completing the study per 
treatment group) is needed for 90% power to show a 1.6 difference in migraine days (assuming a common standard 
deviation [SD] of 5.2 days) at an alpha level of 0.05. Assuming a 12% discontinuation rate, 256 patients per 
treatment group will be randomized.
Efficacy Analysis: For the purpose of this study, a migraine day is endorsed when at least 1 of the following 
situations occur:

a calendar day (0:00 to 23:59) demonstrating at least 2 consecutive hours of a headache meeting 
criteria for migraine with or without aura

a calendar day (0:00 to 23:59) demonstrating at least 2 consecutive hours of a headache meeting 
criteria for probable migraine, a migraine subtype where only 1 migraine criterion is missing

a calendar day (0:00 to 23:59) demonstrating a headache of any duration that was treated with 
migraine-specific medications (triptans and ergot compounds)

Analysis of Primary Efficacy Endpoint: The primary efficacy endpoint, the mean change from baseline (28-day 
run-in period) in the monthly average number of migraine days during the 12-week period after the 1st dose of study 
drug, will be analyzed using an analysis of covariance method. The model will include treatment, gender, country, 
and baseline preventive medication use as fixed effects, and baseline number of migraine days and years since onset 
of migraines as covariates. Ninety-five percent confidence intervals will be constructed for the least squares mean
differences between each TEV-48125 group and the placebo group.
Analysis of Secondary and Exploratory Efficacy Endpoints: The same analysis used for the primary efficacy 
endpoint will be performed for the continuous secondary and exploratory efficacy endpoints. For the proportion of 
responders, defined as 50% or more reduction from baseline in the monthly average number of migraine days, 
Cochran-Mantel-Haenszel test will be used.
Multiple Comparisons and Multiplicity: A fixed-sequence (hierarchical) testing procedure will be implemented to 
control the type 1 error rate at 0.05. The sequence of comparisons will be described in detail in the statistical 
analysis plan.
Safety and Tolerability Analyses: All adverse events will be coded using the Medical Dictionary for Regulatory 
Activities. Each patient will be counted only once in each preferred term or system organ class category for the 
analyses of safety. Summaries will be presented for all adverse events (overall and by severity), adverse events 
determined by the investigator to be related to study drug (defined as related or with missing relationship) (overall 
and by severity), serious adverse events, and adverse events causing withdrawal from the study. Patient listings of 
serious adverse events and adverse events leading to withdrawal will be presented.
Local tolerability findings will be listed and summarized descriptively.
Changes in laboratory and vital signs measurement data will be summarized descriptively. All values will be 
compared with prespecified boundaries to identify potentially clinically significant changes or values, and such 
values will be listed.
The use of concomitant medications will be summarized by therapeutic class using descriptive statistics. 
Concomitant medications will include all medications taken while the patient is treated with study drug.
Safety data will be summarized descriptively overall and by treatment group. For continuous variables, descriptive 
statistics (n, mean, SD, median, minimum, and maximum) will be provided for actual values and changes from 
baseline to each time point. For categorical variables, patient counts and percentages will be provided. Descriptive 
summaries of serious adverse events, patient withdrawals due to adverse events, and potentially clinically significant 
abnormal values (clinical laboratory or vital signs) based on predefined criteria will also be provided.
If any patient dies during the study, a listing of deaths will be provided, and all relevant information will be 
discussed in the patient narrative included in the clinical study report.
Pharmacokinetic Analysis: Pharmacokinetic plasma concentration results (TEV-48125) will be tabulated 
descriptively at each planned sampling time point by treatment group.
Pharmacokinetic/Pharmacodynamic Analysis: The pharmacokinetic/pharmacodynamic relationship will be 
estimated by compartmental techniques. The pharmacokinetic parameters will be based on TEV-48125 
measurements. The pharmacodynamic will be the efficacy responses. 
The pharmacokinetic/pharmacodynamic relationship will be estimated using the most appropriate model after 
comparing different candidate models for their quality of fit. Covariates that may affect the 
pharmacokinetic/pharmacodynamic relationship will be tested for inclusion in the model. This analysis will be 
reported separately.

Immunogenicity Analysis: Summary of immunogenicity results will be provided, and the incidence of 
immunogenicity will be calculated. The impact of immunogenicity on the pharmacokinetic profile, drug efficacy, 
and clinical safety will be evaluated. This impact analysis will be reported separately.
Biomarker Analysis: Biomarker analysis will include logistic regression, receiver operating characteristic curves, 
and summary statistics. Results will be reported separately.

BACKGROUND INFORMATION
1.1.
Introduction
Migraine is a prevalent condition characterized by attacks of headache and associated symptoms 
(such as nausea, photophobia, or phonophobia). The 2 most common forms of migraine, 
migraine without aura and migraine with aura, occur on less than 15 days per month and are 
referred to as episodic forms of migraine (ie, EM) (Lipton et al 2007). However, approximately
3% of individuals with EM evolve, in any given year, to a significantly more disabling condition 
called CM (Bigal et al 2008, Lipton et al 2007,Scher et al 2003). Individuals with CM present 
with headaches of any severity on 15 or more days per month and have full-blown migraine on at 
least 8 days per month (Classification Committee of the International Headache Society [IHS],
2013). A sizable proportion of individuals with CM experiences daily headaches and, therefore, 
faces considerable disability (Bigal and Lipton 2008).
The pathophysiology of migraine involves central and peripheral events. Activation of structures 
in the brainstem are involved in the modulation of sensory activity, which is impaired during 
migraine attacks. Chronic dysfunction in these structures predisposes migraineurs not only to 
migraine attacks, but to increased headache frequency (Goadsby and Hargreaves 2008). 
Furthermore, the activation of these structures is also associated with inflammation and protein 
extravasation at the level of the meningeal blood vessels, muscles and other structures innervated 
by the trigeminal nerve. This combination of peripheral insults (inflammation and plasma protein 
extravasation) with impairment of the inhibitory pain mechanisms at the level of brainstem is 
paramount to frequent migraines (Goadsby et al 2002).
Calcitonin gene-related peptide (CGRP) is a well-studied neuropeptide found at the centers of 
the migraine processes, both centrally and peripherally (Eftekhari and Edvinsson 2010). Its role 
in migraine pathophysiology was suggested more than 20 years ago (Edvinsson and Goadsby 
1990, Goadsby et al 1990). Jugular levels of CGRP are increased during migraine attacks, and 
intravenous (iv) CGRP administration induces migraine-like headache in most individuals with 
migraine (Ashina et al 2000, Hansen et al 2010). Calcitonin gene-related peptide is therefore 
involved in the pathophysiology of migraine at all levels, peripherally (vasodilation, 
inflammation and protein extravasation), at the trigeminal ganglion, and inside the brain (Ho et al 
2010). Inhibition of CGRP has demonstrated efficacy in the treatment of EM (Hewitt et al 2011,
Ho et al 2008, Olesen et al 2004).
The goals of migraine treatment are to relieve pain, restore function, reduce headache frequency, 
and to prevent progression of EM to CM. Pharmacological interventions for the treatment of 
migraine include acute (symptomatic) treatments and daily preventive medications. The latter is 
indicated for patients with CM and may be appropriate patients with EM who have significant 
disability with migraine attacks (>3 days per month with headache-related disability), 
contraindications to triptans or other vasoactive medications, significant adverse effects from 
triptans, and patients with severe or prolonged attacks (Lipton and Silberstein 2015). Currently 
available drug therapies for preventive treatment of migraine include antiepileptic drugs, 
beta-blockers, triptans, antidepressants, angiotensin receptor blockers, angiotensin-converting 
enzyme inhibitors, serotonergic agents, calcium channel blockers, nonsteroidal 
anti-inflammatory drugs, opioids, and direct vascular smooth muscle relaxants. Although there

are more than 40 medications within these classes of drugs that are used with varying response 
rates to prevent migraine, only 5 marketed drugs are approved by the Food and Drug 
Administration (FDA) in the United States (US) for the preventive treatment of migraine; 4 of 
them are approved for the prophylaxis of migraine: propranolol, timolol maleate, divalproex 
sodium, and topiramate. The clinical trials (Brandes et al 2004, Klapper 1997, Mathew et al 
1995, Nadelmann et al 1986, Silberstein et al 2004) that supported registration of these drugs for 
this indication were conducted before the establishment of CM as a single entity and generally 
included patients with headaches on less than 15 days per month. Only 1 medication, 
onabotulinumtoxinA, is approved for prophylaxis of CM (Lipton and Silberstein 2015).
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; these 
activities can lead to unwanted consequences such as cell lysis, opsonization, and cytokine 
release and inflammation (Armour et al 1999, Zeller et al 2008).
The pharmacokinetics and tolerability of TEV-48125 (iv doses ranging from 0.2 to 2000 mg and 
subcutaneous [sc] doses of 225 mg and 900 mg) has been well-characterized in the Phase 1 
development program (see Section 1.3.2.1). Furthermore, the safety and effectiveness of 
TEV-48125 has been demonstrated in a randomized double-blind, placebo controlled Phase 2 
study 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 2 study of 2 sc dosing regimens of TEV-48125 (monthly 
TEV-48125 at 675 or 225 mg) in patients with EM (see Section 1.3.2.2). The acceptable 
tolerability, long terminal elimination half-life (t½, approximately 45 days) and ability to 
administer sc make TEV-48125 an attractive therapeutic candidate for the preventive treatment 
of CM and EM.
1.2.
Name and Description of Investigational Product
TEV-48125 (formerly LBR-101, PF-04427429, or RN307) is a fully humanized IgG2a/kappa 
monoclonal antibody derived from a murine precursor. TEV-48125 is being developed for 
administration by the sc route. A more detailed description of the product is given in Section 3.9.
1.3.
Findings from Nonclinical and Clinical Studies
1.3.1.
Nonclinical Studies
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 monkey.

Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
35
Safety pharmacology parameters of TEV-48125 were assessed in the pivotal 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 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 iv or sc. 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 pivotal 6-month chronic toxicity study in 
monkeys following once-weekly sc dosing at dosage levels of up to 300 mg/kg/week, achieving 
high exposure throughout the study, no microscopic findings 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 typical of a humanized 
IgG2 molecule, with low mean plasma clearance, low volume of distribution at steady state, and 
a long t½. Exposure as defined by the maximum observed plasma drug 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, pivotal 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.
Further details may be found in the current Investigator’s Brochure.
1.3.2.
Clinical Studies
To date, TEV-48125 has been studied in 6 Phase 1 studies in healthy volunteers and 
2 Phase 2b studies in migraine patients. In total, 484 subjects (118 healthy volunteers and 
366 migraine patients) received at least 1 dose of TEV-48125 via iv or sc administration.
A brief summary of clinical pharmacology and clinical safety and efficacy studies of TEV-48125 
follows. Further details may be found in the current Investigator’s Brochure.
1.3.2.1.
Clinical Pharmacology Studies
A total of 118 subjects received at least 1 dose of TEV-48125 across 6 completed Phase 1 studies 
at doses ranging from 0.2 through 2000 mg. Studies included 2 single-dose-escalation 
pharmacokinetic and pharmacodynamic studies in healthy men (Studies B0141001 and 

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
36
B0141002); a 2-cohort, placebo-controlled, cross-over study to examine the acute effects 
administration of TEV-48125 on capsaicin flare response in healthy men (Study B0141006); a 
parallel-group, repeat-dose study of TEV-48125 in healthy men and women (Study B0141007); 
a single-dose study evaluating the safety, tolerability, and pharmacokinetics of doses up to 
2000 mg administered to healthy women (Study LBR-101-008); and a single-dose study 
comparing the safety, tolerability, absolute bioavailability, and pharmacokinetics if sc and iv 
TEV-48125 in healthy men and women (Study LBR-101-011).
Based on noncompartmental analysis, TEV-48125 exposure increases with dose in an 
approximately dose-proportional manner from 225 to 900 mg following sc administration and 
over the dose range from 100 to 2000 mg following iv infusion. The Cmax occurred near the end 
of the iv infusion (median time to Cmax [tmax] of 1 to 5 hours after the start of the infusion), and 
Cmax was prolonged as indicated by the delayed tmax (median tmax 96 to 108 hours postdose) after 
sc administration. The mean t½ following sc administration was similar to that observed after iv 
administration for each dose level. The t½ ranged from approximately 642 to 770 hours 
(approximately 27 to 32 days) at the 225-mg dose level, and the t½ ranged from approximately 
1140 to 1200 hours (approximately 48 to 50 days) at the 900-mg dose level. Absolute 
bioavailability of the sc dose was approximately 55%.
TEV-48125 was well tolerated with favorable safety profile. The treatment-emergent adverse 
events reported in the Phase 1 studies were predominantly mild to moderate in severity. A 
specific “pattern of adverse events” that could be associated with a dose or a dose range of 
TEV-48125 has not been identified, nor has a maximally tolerated dose been identified. The 
most common treatment-emergent adverse events reported were headache, nasopharyngitis, 
gastroenteritis, and back pain. There were no deaths. One serious adverse event reported as 
“thoracic aortic aneurysm aggravated” in an individual receiving a single iv 300-mg TEV-48125 
dose resolved.
TEV-48125 does not appear to be 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 studies.
1.3.2.2.
Clinical Safety and Efficacy Studies
The safety, tolerability, and efficacy of TEV-48125 was evaluated in migraine patients in 
2 Phase 2b studies. The first study was a multicenter, randomized, double-blind, 
placebo-controlled, parallel-group study comparing the efficacy, safety, tolerability, and 
pharmacokinetics of 2 doses of TEV-48125 with placebo in 264 patients with CM 
(Study LBR-101-021). Following a 28-day run-in period, participants were randomized and 
treated sc once monthly for 3 months. One active group received a 1st dose of 675 mg followed 
by 225 mg on the subsequent 2 months. The other active group received 900 mg per month. The 
mean change in headache hours relative to baseline for each TEV-48125 dose arm was 
significantly different from the placebo arm at 3 months (primary endpoint), and the study was 

Placebo-Controlled Study–Episodic Migraine

Study TV48125-CNS-30050
37
also positive at 2 and 1 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 serious treatment-related adverse events 
were reported. Most adverse events were mild to moderate. No safety signals were observed in 
the clinical laboratory tests, vital signs, physical examination, or ECGs.
The second study was a multicenter, randomized, double-blind, placebo-controlled, 
parallel-group study comparing the efficacy, safety, tolerability, and pharmacokinetics of 2 doses 
of TEV-48125 with placebo in 297 patients with EM (Study LBR-101-022). Following a 28-day 
run-in period, participants were randomized and treated sc once monthly for 3 months. Two 
active doses 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 at month 3 relative to baseline for both 
TEV-48125 dose arms was significantly different from placebo at 3 (primary endpoint), 2, and 
1 months. Secondary and exploratory endpoints were also positive for the duration of the study. 
Both doses were well tolerated, and no serious treatment-related adverse events were reported. 
Most adverse events were mild to moderate and the lowest dose had a numerically lower number 
of adverse events relatively to placebo. No safety signals were observed in the clinical laboratory 
tests, vital signs, physical examination, or ECGs.

Known and Potential Risks and Benefits of TEV-48125 
Information regarding risks and benefits of TEV-48125 to human patients may be found in the 
current Investigator’s Brochure.
1.4.1.1.
Risks of TEV-48125
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. None of the identified risks are considered 
important risks.
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.
As described in Section 1.3.2.2, sc TEV-48125 has generally been well tolerated over the ranges 
of doses evaluated (single doses of 0.02 to 2000 mg in healthy volunteers, multiple doses of 
30 to 300 mg in healthy volunteers, and multiple doses of 225 to 900 mg in migraine patients). 
The most common treatment-emergent adverse events were mild to moderate transient general 
administration site disorders/reactions. Other commonly reported treatment-emergent adverse 
events were headache, back pain, and upper respiratory tract infection.

Benefits of TEV-48125
As described in Section 1.3.2.2, results from Phase 2 clinical studies have demonstrated 
statistically significant reductions in mean headache hours after 1, 2, and 3 months of 
TEV-48125 treatment in patients with CM and statistically significant reductions in monthly

migraine days after 1, 2, and 3 months of TEV-48125 treatment in patients with EM. Results for 
several secondary/exploratory endpoints also showed TEV-48125 to be superior to placebo.

Overall Risk and Benefit Assessment for This Study
Based on the current safety profile and the demonstrated efficacy of the sc TEV-48125 dosage 
form, the overall risk and benefit assessment for this study is favorable.
1.5.
Selection of Drugs and Dosages
A detailed description of study drug administration is presented in Section 5.1.
1.5.1.
Justification for Dosage of Active Drug
The TEV-48125 doses and dosing regimens to be evaluated in this double-blind study were 
selected on the basis of animal pharmacodynamic and pharmacokinetic data, 
6 pharmacokinetic/safety studies in healthy volunteers, 2 safety/efficacy study in patients with 
migraine, and population pharmacokinetic and pharmacokinetic/pharmacodynamic modeling and 
simulations.
The pharmacodynamics of TEV-48125 were examined in animal models by characterization of 
the ability of TEV-48125 to block CGRP functions in vivo (see Section 1.3.1). Specifically,
neurogenic vasodilation by capsaicin application on the skin was used to induce a 
CGRP-mediated increase in vasodilatation or skin blood flow in cynomolgus monkeys. In this 
study, TEV-48125 (dosed as a single iv bolus at 1, 10, or 100 mg/kg) produced a dose-dependent 
inhibition of the capsaicin-induced skin flare response. The magnitude and duration of the 
inhibition produced by TEV-48125 were dose-dependent, with the 10 and 100 mg/kg doses 
showing inhibition out to 56 days postdose. Based on body surface area conversion, these doses 
are equivalent to single doses of approximately 225 and 2000 mg, respectively, in patients with 
migraine. Therefore, the 225-mg dose was considered to be a reasonable and pragmatic choice 
for the lowest dose with potential for effectiveness.
Based on data from the pharmacokinetic and pharmacodynamic studies in animal models and the 
pharmacokinetics, safety, and tolerability of TEV-48125 from Phase 1 studies in healthy 
volunteers, 2 dose regimens were selected for sc administration in the Phase 2b study in patients 
with EM for a treatment period of 3 months. The 2 active arms were 225 and 675 mg 
administered monthly. The results of the Phase 2b study demonstrated that both dose regimens 
are effective, safe, and well tolerated by EM patients. The mean change in number of migraine 
days relative to baseline for both TEV-48125 dose arms were significantly different from the 
placebo arm at 3 months (primary endpoint), and the study was also strikingly positive at 
2 months and 1 month. Although a maximum tolerated dose was not reached in the Phase 2b 
study, and doses up to 2000 mg were observed to be safe in healthy volunteers, it is considered 
best practice to select the lowest effective dose known for administration. Therefore, the lowest 
dose from the Phase 2b study, 225 mg TEV-48125 administered monthly, was preserved for the 
Phase 3 study in patients with EM. A 2nd active treatment group will receive TEV-48125 at 
675 mg quarterly to examine the potential for loss of efficacy within a 3-month treatment period 
following a single sc administration. In a simulation, a low dose of 225 mg once in 3 months was 
evaluated and found to be with limited efficacy. Thus, the next supported higher dose of 675 mg 
was selected for this regimen.

Compliance Statement
This study will be conducted in full accordance with the International Conference on 
Harmonisation (ICH) Good Clinical Practice (GCP) Consolidated Guideline (E6) and any 
applicable national and local laws and regulations (eg, Title 21 Code of Federal Regulations 
[21CFR] Parts 11, 50, 54, 56, 312, and 314, European Union [EU] Directive 2001/20/EC on the 
approximation of the laws, regulations and administrative provisions of the Member States 
relating to the implementation of GCP in the conduct of clinical studies on medicinal products 
for human use). Any episode of noncompliance will be documented.
The investigator is responsible for performing the study in accordance with this protocol and the 
applicable GCP guidelines referenced above for collecting, recording, and reporting the data 
accurately and properly. Agreement of the investigator to conduct and administer this study in 
accordance with the protocol will be documented in separate study agreements with the sponsor 
and other forms as required by national authorities in the country where each investigational 
center is located.
The investigator is responsible for ensuring the privacy, health, and welfare of the patients during 
and after the study and must ensure that trained personnel are immediately available in the event 
of a medical emergency. The investigator and the applicable study staff must be familiar with the 
background to, and requirements of, the study and with the properties of the study drug(s) as 
described in the Investigator’s Brochure or prescribing information.
The principal investigator at each investigational center has the overall responsibility for the 
conduct and administration of the study at that center and for contacts with study management, 
with the Independent Ethics Committee (IEC)/Institutional Review Board (IRB), and with local 
authorities.
1.7.
Population to be Studied and Justification
The study population will be composed of female and male patients, aged 18 to 70 years,
inclusive, with a history of migraine (as defined by International Classification of Headache 
Disorders, 3rd revision [ICHD-3] criteria [Classification Committee of the IHS, 2013]) for at least 
12 months prior to screening and EM prospectively documented via a review of headache data 
recorded daily during a 28-day run-in period in an electronic headache diary device.
Because headache consortium guidelines recommend preventive therapies for patients with EM 
occurring on 4 or more days per month due to the frequency of headaches and high degree of 
disability, patients using no more than 1 preventive medication at the time of study enrollment 
will be allowed to remain on the medication if the medication has at least moderate evidence of 
efficacy for migraine (Silberstein et al 2012). Patients must be on a stable dose and regimen of 
the preventive medication for at least 2 months prior to study entry (ie, before the run-in period), 
and they cannot change the dose and regimen during the study. The total number of patients 

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
40
receiving concomitant preventive medication during the study will not exceed 30% of the total 
sample size of the study.
Episodic migraine is a highly prevalent condition and a significant cause of disability, especially 
in patients with high frequency EM. Furthermore, 3% to 6% of patients with EM evolve in any 
given year to CM, which is significantly more disabling (Scher et al 2003). Risk factors for 
evolution from EM to CM include high headache frequency and the use of specific classes of 
acute medication, including barbiturates and opiates (Bigal et al 2008).
Aside from limiting migraine-associated disability, it is expected that effective preventive 
migraine medications should decrease the likelihood that a patient with EM will evolve to CM. 
However, available preventive medications have variable response rates and are associated 
adverse effects. In addition, only 4 are approved for preventive treatment of EM (Lipton and 
Silberstein 2015, Shamiliyan et al 2013).
1.8.
Location and Timing of Study 
This study is planned to be conducted in approximately 15 countries, including North and South 
America, the European Union, and Asia Pacific, at approximately 140 centers. It is expected to 
start in in 1Q 2016 and have a duration of approximately 21 months. Additional centers will be 
added, if needed. Expected duration of the study may also be extended dependent on enrollment 
speed and other factors.

STUDY DESIGN
3.1.
General Design and Study Schema
This is a 16-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group 
study to compare the safety, tolerability, and efficacy of 2 dose regimens of sc TEV-48125 and 
placebo in adults with EM. The study consists of a screening visit, a 28-day run-in period, and a 
12-week (84-day) treatment period, including a final evaluation at week 12 (end-of-treatment 
[EOT] visit, approximately 4 weeks [28 days] after the final dose of study drug).
The study population will be composed of female and male patients, aged 18 to 70 years, 
inclusive, with a history of migraine (as defined by ICHD-3 criteria [Classification Committee of 
the IHS, 2013]) for at least 12 months prior to screening and EM prospectively documented via a 
review of headache data recorded daily during a 28-day run-in period in an electronic headache 
diary device.
Patients using no more than 1 preventive medication at the time of study enrollment will be 
allowed to remain on the medication if the medication has at least moderate evidence of efficacy 
for migraine (Silberstein et al 2012). Patients should not be using concomitant preventive 
migraine medications (presented in Appendix B) at the time of the screening visit, and will not 
be allowed to initiate these medications after study start. A small subgroup of patients 
(approximately 30%) will be allowed to use concomitant migraine preventive medications 
(presented in Appendix A), and no changes in these medications will be allowed until the last
study assessments are complete. Patients will be allowed to use acute medications to treat acute 
migraine attacks as needed.
After completing the informed consent process (screening visit [visit 1]), patients will be 
screened for eligibility. Eligible patients will enter a 28-day run-in period. Headache information 
will be captured daily throughout study participation using the electronic headache diary device. 
After completing the run-in period, patients will be asked to return to the study center on day 0 
(visit 2). Patients who have confirmed EM with headache of any type on 6 to 14 days and 
migraine on at least 4 days and meet all other eligibility criteria (including electronic headache 
diary compliance criteria during the 28-day run-in period) will be randomly assigned in a 
1:1:1 ratio to 1 of 3 treatment groups:

monthly sc administration of TEV-48125 at 225 mg

sc administration of 675 mg of TEV-48125 at visit 2 followed by monthly sc placebo

monthly sc administration of placebo
(Note: For this study, monthly dosing refers to dosing approximately every 4 weeks [28 days].)
Randomization will be performed using electronic interactive response technology (IRT). 
Patients will be stratified based on gender, country, and baseline preventive migraine medication 
use (yes, no) to ensure balance for the covariates (treatment group, preventive migraine
medication use, country, and gender). The total number of patients receiving concomitant 
preventive medication during the study will not exceed 30% of the total sample size of the study.

49
Blinded treatment will be administered sc once monthly (ie, approximately every 4 weeks) for a 
total of 3 doses. First treatment administration will occur at visit 2 (day 0), and additional doses 
will be administered at visits 3 and 4. Final study assessments will be performed at visit 5 (EOT 
visit), approximately 4 weeks after administration of the 3rd and final dose of study drug.
Headache information will be captured daily during the entire study using an electronic headache 
diary device. Assessments of migraine-related disability and change in quality of life (using the 
MIDAS questionnaire, PHQ-2/PHQ-9, MSQOL questionnaire, EQ-5D-5L questionnaire, and 
PGIC scale, and WPAI questionnaire); safety evaluations; blood draws for pharmacokinetic, 
immunogenicity, and biomarker analysis; and urine sampling for biomarker analysis will be 
performed throughout the study according to the schedule of assessments (Table 1). In addition, 
patients who consent to pharmacogenomic assessment will provide a blood sample for testing.
Upon completion of the final study assessments patients who complete all scheduled visits may 
be eligible to enter a long-term safety and efficacy study (Study TV48125-CNS-30051), 
consisting of a 12-month double-blind treatment period and a 6.5-month follow-up period. 
Patients receiving active study drug in the current study will continue receiving the same 
treatment (ie, monthly sc TEV-48125 at 225 mg or quarterly sc TEV-48125 at 675 mg), and 
patients receiving placebo in the current study will be randomized in a 1:1 ratio to receive 
monthly sc TEV-48125 at 225 mg or quarterly sc TEV-48125 at 675 mg during the long-term 
safety and efficacy study. This long-term safety and efficacy study is beyond the scope of this 
protocol. A separate protocol will be issued. Patients who withdraw from the study before 
completing the 12-week evaluation period will have EOT visit (visit 5) procedures and 
assessments performed on the last day they receive the study drug or as soon as possible 
thereafter. Those patients who do not enter the long-term safety and efficacy study for any reason 
will be offered to enter the long term safety extension for the purpose of evaluating ADA 
approximately 7.5 months (225 days [the approximate equivalent of 5 half-lives]) after 
administration of the last (3rd) dose of study drug in this study.
The assessments and procedures performed during each study visit are detailed in Table 1 and 
Section 3.14. The study schema is presented in Figure 1.
The end of the study is defined as the date the last patient attends the EOT/early withdrawal visit 
(visit 5).
A total of 768 patients are planned to be randomized in a 1:1:1 ratio (256 patients per treatment 
group) to receive 3 monthly sc doses of TEV-48125 at 225 mg, 1 monthly sc dose of TEV-48125 
at 675 mg followed by 2 monthly sc doses of matching placebo, or 3 monthly sc doses of 
matching placebo.

3.2.
Justification for Study Design
A randomized, double-blind, placebo-controlled, parallel-group design is appropriate given the 
objectives of this study. Furthermore, this design is consistent with the recommendations of the 
Classification Committee of the IHS for controlled trials of preventive drugs in migraine (Tfelt-
Hansen et al 2012).
The dose planned for administration at visit 2 (1st dose) for patients randomized to receive 
TEV-48125 at 675 mg followed by monthly sc placebo requires administration of 3 × 1.5-mL 
injections. In order to blind the treatment arms based on both dose-volume and number of 
injections, each patient will receive three 1.5-mL sc injections at visit 2: three 1.5-mL sc 
injections of active drug, one 1.5-mL sc injection of active drug and two 1.5-mL injections of 
placebo, or three 1.5-mL injections of placebo. Each patient will receive a single 1.5-mL sc 
injection of active drug (225 mg) or placebo at visits 3 and 4 according to their randomized 
treatment.

Primary and Secondary Efficacy Measures and Time Points
A description of the efficacy measures is provided in Section 6.
3.3.1.
Primary Efficacy Measure and Time Points
The primary efficacy endpoint for this study will be derived from headache data (ie, occurrence 
of headache, duration of headache, maximum severity of headache, and acute migraine-specific 
medication use) collected daily using an electronic headache diary device. 
Eligible patients will receive training on the use of the electronic headache diary device and will 
be informed of compliance requirements at screening. Patients will complete electronic headache 
diary entries with questions about the previous day beginning on day -27 (the day after the 
screening visit) through the EOT/early withdrawal visit. The electronic headache diary device 
will allow entry of headache information for up to 48 hours after a given day.
3.3.2.
Secondary Efficacy Measure and Time Points
The secondary efficacy endpoints will be derived from headache data (ie, occurrence of 
headache, duration of headache, maximum severity of headache, and acute migraine-specific 
medication use) collected daily using an electronic headache diary device. In addition, 
migraine-related disability will be assessed using the MIDAS questionnaire, completed at time 
points specified in Table 1.
3.4.
Safety and Tolerability Measures and Time Points
Safety and tolerability will be assessed at time points specified in Table 1 using the following 
measures:

inquiries about adverse events

inquiries about concomitant medication usage

safety laboratory tests (serum chemistry, hematology, coagulation, and urinalysis)

serum/urine beta-human chorionic gonadotropin (β-HCG) test (women of 
childbearing potential only)

12-lead ECGs

vital signs measurements (systolic and diastolic blood pressure, pulse, temperature, 
and respiratory rate)


Pharmacokinetic, Biomarker, and Immunogenicity Measures and 
Time Points
A description of the pharmacokinetic, biomarker, and immunogenicity measures is provided in 
Section 8.
3.5.1.
Pharmacokinetic Measures and Time Points
Blood samples for pharmacokinetics analysis of TEV-48125 will be collected from all patients at 
time points specified in Table 1 for the purpose of pharmacokinetic/pharmacodynamic 
relationship assessment. The pharmacodynamic parameters will be the efficacy responses.
The actual date and time of each blood sample, as well as the date and time of the last study drug 
dose prior to the sample, will be recorded in the case report form (CRF).
TEV-48125 plasma concentration will be measured using a validated assay.
3.5.2.
Immunogenicity Measures and Time Points
Blood samples for immunogenicity analysis will be collected at time points specified in Table 1.
3.5.3.
Biomarker Measures and Time Points
Biomarker blood and urine samples will be collected from all patients at time points specified in 
Table 1, and a blood sample will be collected from patients who consent to pharmacogenomic 
analysis at visit 2 or any visit thereafter.
3.6.
Exploratory/Other Efficacy Measures and Time Points
The following exploratory efficacy measures will be assessed at time points specified in Table 1:

exploratory efficacy endpoints derived from headache data (ie, occurrence of 
headache, duration of headache, maximum severity of headache, and acute 
migraine-specific medication use), which are collected daily using an electronic 
headache diary device

PHQ-2/PHQ-9 (Note: Patients will first respond to the PHQ-2. They will respond to 
questions 3 through 9 [unique questions] of the PHQ-9 only if the PHQ-2 is positive.)



PGIC scale completed

WPAI questionnaire
3.7.
Randomization and Blinding
The sponsor, investigators, study staff (except for staff involved in bioanalytical analyses), and 
patients will be blinded to treatment assignment. A computer-generated master randomization 
list will be provided to drug packaging facilities. Packaging vendor(s) will package active drug
and placebo into single-visit kits according to Good Manufacturing Practice procedures. Kits will 
be identical in appearance and contain 1 prefilled syringe with active drug or placebo. Adequate 

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
53
kit supply for upcoming study visits will be managed by IRT and kept (refrigerated at 2°C to 
8°C) on site.
This is a randomized study with stratification based on gender, country, and baseline preventive 
medication use (yes, no). Each patient will undergo randomization in a 1:1:1 ratio within the 
stratum to which he or she belongs to receive 1 of the 2 TEV-48125 dose regimens or placebo, as 
assigned by the IRT. The IRT will manage initial drug supply, maintenance of adequate study 
drug supplies on site, and study randomization centrally. At the time of each study visit, the IRT 
will be queried, and site personnel will retrieve and administer a 1.5-mL volume from each 
syringe contained in the appropriately numbered kit(s).
3.8.
Maintenance of Randomization and Blinding
3.8.1.
Randomization
Patient randomization codes will be maintained in a secure location within Teva Global 
Biometrics or in a secure location with the vendor contracted to create the list. At the time of 
analysis, when treatment codes are needed, the Teva statistician assigned to the study will make 
a request to unblind and will receive the unblinded codes.
3.8.2.
Blinding/Unblinding
Pharmacokinetic data may be assessed during the study. Personnel responsible for bioanalysis 
will be provided with the randomization code in order to facilitate the analysis. However, the 
personnel responsible for bioanalysis will not have access to clinical safety and efficacy data and 
will provide concentration data to other personnel in a manner that will not identify individual 
patients (ie, a dummy patient identifier will be linked to an individual patient’s concentration 
data).
For information about personnel who may be aware of treatment assignments, see Section 3.7. 
These individuals will not be involved in conduct of any study procedures or assessment of any 
adverse events.
In case of a serious adverse event or pregnancy, or in cases when knowledge of the study drug 
assignment is needed to make treatment decisions, the investigator may unblind the patient’s 
drug assignment as deemed necessary, mainly in emergency situations. Individual treatment 
codes, indicating the treatment randomization for each randomized patient, will be available to 
the investigator(s) and/or pharmacist(s) at the study center via the IRT, both via telephone and 
internet. If possible, the sponsor should be notified of the event prior to breaking of the code. If 
this is not possible, the sponsor should be notified immediately afterwards, and the patient’s drug 
code assignment should not be revealed. Breaking of the treatment code can always be 
performed by the site without prior approval by the sponsor.
When a blind is broken, the patient will be withdrawn from the study, and the event will be 
recorded onto the CRF. The circumstances leading to the breaking of the code should be fully 
documented in the investigator’s study files and in the patient’s source documentation. 
Treatment assignment should not be recorded in any study documents or source document.
In blinded studies, for adverse events that are defined as: suspected unexpected serious adverse 
reaction (SUSAR) (ie, reasonable possibility; see Section 7.1.4), Global Patient Safety and 

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
54
Pharmacovigilance may independently request that the treatment code be revealed (on a 
case-by-case basis) to comply with regulatory requirements. The report will be provided in an 
unblinded manner for regulatory submission. If this occurs, blinding will be maintained for the 
investigator and for other personnel involved in the conduct, analysis, and reporting of the data.

Drugs Used in the Study
A description of administration procedures is given in Section 5.1. Additional details may also be 
found in the current version of the Investigator’s Brochure for TEV-48125.
3.9.1.
Investigational Product
TEV-48125 will be provided as a sterile, unpreserved, colorless to slightly yellow, aqueous 
solution for injection, supplied in a 2.25-mL prefilled syringe for single-use administration, 
containing 150 mg/mL in 16±2.5 mM L-histidine, 0.2-mg/mL polysorbate 80, 84-mg/mL 
sucrose, and 0.136-mg/mL ethylenediaminetetraacetic acid (EDTA).
TEV-48125 will be administered sc at a dose of 225 mg at visit 2 (for patients randomized to 
both TEV-48125 dosing regimens), and TEV-48125 will be administered sc at a dose of 225 mg 
at visits 3 and 4 (for patients randomized to the monthly TEV-48125 at 225 mg dosing regimen). 
Each dose will be separated by approximately 28 days. A more detailed description of 
administration procedures is given in Section 5.1.
3.9.2.
Placebo
Placebo will be provided as a sterile solution of 16±2.5 mM L-histidine, 0.2-mg/mL 
polysorbate 80, 84-mg/mL sucrose, and 0.136-mg/mL EDTA, presented as 2.25 mL per syringe.
Placebo will be administered sc at visits 2, 3, and 4 (for patients randomized to the placebo 
treatment group) or visits 3 and 4 (for patients randomized to the TEV-48125 
675 mg/placebo/placebo dosing regimen). A more detailed description of administration 
procedures is given in Section 5.1.
3.10.
Drug Supply and Accountability
3.10.1.
Drug Storage and Security
The study drug (TEV-48125 and placebo) must be stored refrigerated at 2°C to 8°C (36°F to 
46°F), protected from light; the site should have a process for monitoring the drug storage 
temperature. TEV-48125 and placebo supplies must be kept in a secure area (eg, locked 
refrigerator). 
3.10.2.
Drug Accountability
Each study drug shipment will include a packing slip listing the contents of the shipment, drug 
return instructions, and any applicable forms.

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
55
Each investigator is responsible for ensuring that deliveries of study drug and other study 
materials from Teva are correctly received, recorded, handled, stored, accounted for, and used in 
accordance with this protocol. In addition, each investigator is responsible for ensuring that study 
drug and other materials from Teva are correctly, safely, and properly disposed of in accordance 
with local regulations.
A record of study drug accountability (ie, study drug and other materials received, used, retained, 
returned, or destroyed) must be prepared and signed by the principal investigator or designee, 
with an account given for any discrepancies.
3.11.
Duration of Patient Participation and Justification
This study will consist of a screening visit, a 28-day run-in period, and a 12-week (84-day) 
double-blind treatment period. Patients are expected to participate in this study for approximately 
16 weeks. Patients completing this study may enroll in the double-blind, long-term safety and 
efficacy study (Study TV48125-CNS-30051). Those patients who do not enter the long-term 
safety and efficacy study for any reason will be offered to enter the long-term safety extension 
for the purpose of evaluating ADA approximately 7.5 months (225 days) after administration of 
the last (3rd) dose of study drug in this study. Thus, patient participation for these patients will 
last approximately 10.5 months.
See Section 12.4 for the definition of the end of the study.
The durations of the run-in and double-blind treatment periods align with Classification 
Committee of the IHS guidelines for controlled trials for the preventive treatment of migraine 
(Tfelt-Hansen et al 2012).
Patients who do not enroll in the long-term safety and efficacy study for any reason but who 
enter the long-term safety extension for the purpose of evaluating ADA will return 
approximately 7.5 months (225 days, the approximate equivalent of 5 half-lives) after the last 
dose of study drug. This is consistent with the 2009 FDA Guidance for Industry on Assay 
Development for Immunogenicity Testing of Therapeutic Proteins; a complete washout of the 
drug from the circulating blood is expected after approximately 7.5 months (≥5 half-lives), 
allowing a more precise evaluation of ADA.
3.12.
Stopping Rules and Discontinuation Criteria
There are no formal rules for early termination of this study. During the conduct of the study, 
serious adverse events will be reviewed (see Section 7.1.5) as they are reported from the 
investigational center to identify safety concerns. The study may be terminated by the sponsor at 
any time.
A patient may discontinue participation in the study at any time for any reason (eg, lack of 
efficacy, consent withdrawn, and adverse event). The investigator and/or sponsor can withdraw a 
patient from the study at any time for any reason (eg, protocol violation or deviation as defined 
in Section 11.1.2, noncompliance, or adverse event). In addition, patients with abnormal hepatic 
laboratory values (eg, ALT, AST, ALP, gamma-glutamyl transpeptidase [GGT], total bilirubin, 
or international normalized ratio [INR]) may meet criteria for discontinuation from the study 
drug as summarized in Appendix E.

3.13.
Source Data Recorded on the Case Report Form
All patient data must have supportive original source documentation in the medical records, or 
equivalent, before they are transcribed onto the CRF. Data may not be recorded directly onto the 
CRF and considered as source data unless the sponsor provides written instructions specifying 
which data are permitted to be recorded directly onto the CRF.
Source data, including test results and/or assessments (eg, clinical laboratory, central ECG 
evaluation center, and electronic headache diary data) collected by other institutions outside of 
the study center, are sent to the investigational center where they are retained, but not entered 
into the CRF unless otherwise noted in the protocol. These data may also be sent electronically 
to the sponsor (or organization performing data management) for direct entry into the clinical 
database (see Section 13.1). All data from other institutions will be available to the investigator.
The CRFs are filed in the sponsor’s central file.
3.14.
Study Procedures
Study procedures and assessments with their timing are summarized in Table 1. Detailed by-visit 
information is provided in the sections following the table. Detailed descriptions of each 
assessment are provided in Section 6 (efficacy assessments), Section 6.2 (safety assessments), 
and Section 8 (pharmacokinetic and other assessments).

3.14.1.
Procedures for Screening (Visit 1[Day –28])
A signed and dated informed consent form will be obtained before screening procedures 
commence (see Section 12.1). Evaluations obtained as part of routine medical care and 
performed during the screening period may be used in place of the protocol-specific evaluations. 
In addition, disease-specific assessments performed within a specified time frame before 
informed consent may be used for the study. Patients will acknowledge and agree to the possible 
use of this information for the study by giving informed consent.
After informed consent is obtained, patients who are screened will be assigned an 8-digit 
identification number such that all patients from each country are given consecutive 
identification numbers in successive order of inclusion. The first 2 digits of the screening number 
will be the number assigned to the country where the investigational center is located, the next 
3 digits will be the investigational center number, and the last 3 digits will be the patient number 
assigned at the investigator center (eg, the 3rd patient screened in the US [country 01] at 
center 101 would be assigned the number of 01101003). The screening number is the permanent 
number assigned to the patient for the duration of study.
After confirmation of study eligibility, patients will be screen failed or randomized into 
Study TV48125-CNS-30049 (ie, patients with CM) or the current study (ie, patients with EM).
For randomized patients, an enrollment number will be assigned consisting of the 8-digit 
screening number and the last 2 digits of the assigned protocol (ie, 49 for Study TV48125-CNS-
30049 or 50 for the current study; in the example above, the enrollment number would be 
01101003-50 for this study).
A patient who is screened and does not meet study entry criteria will not be considered for 
screening again.
The screening visit (visit 1) will take place approximately 28 days before the baseline visit. The 
following procedures will be performed at visit 1:

Obtain written informed consent before any other study-related procedures are 
performed.

Record demographic characteristic including race.

Review inclusion/exclusion criteria.

Review medical and psychiatric history.

Review medication history.

Perform vital signs measurements (includes systolic and diastolic blood pressure, 
pulse, body temperature, and respiratory rate).

Perform triplicate 12-lead ECGs.

Perform a physical examination, including height and weight. Body mass index will 
be calculated from the screening height and weight.

Perform clinical laboratory tests (serum chemistry, hematology, coagulation, and 
urinalysis).

s.
The patient cannot participate or successfully complete the study, in the opinion of 
their healthcare provider or the investigator, for any of the following reasons:

mentally or legally incapacitated or unable to give consent for any reason

in custody due to an administrative or a legal decision, under guardianship, or 
institutionalized

unable to be contacted in case of emergency

has any other condition, which, in the opinion of the investigator, makes the 
patient inappropriate for inclusion in the study
t.
The patient is a study center or sponsor employee who is directly involved in the 
study or the relative of such an employee
4.3.
Justification for Key Inclusion and Exclusion Criteria
The inclusion and exclusion criteria select for patients who meet ICHD-3 revision criteria for 
EM (Classification Committee of the IHS, 2013). Because headache consortium guidelines 
recommend preventive therapies for patients with EM occurring on 4 or more days per month 
due to the frequency of headaches and the high degree of disability, Inclusion Criterion e allows 
for the use of 1 concomitant preventive medication for migraine.
4.4.
Withdrawal Criteria and Procedures
In accordance with the Declaration of Helsinki (in accordance with the applicable country’s 
acceptance), each patient is free to withdraw from the study at any time. The investigator also 
has the right to withdraw a patient from the study in the event of intercurrent illness, adverse 
events, pregnancy (see Section 7.2), or other reasons concerning the health or well-being of the 
patient, or in the event of lack of cooperation. In addition, a patient may be withdrawn from the 
study as described in Sections 3.8, 3.12, 3.14.4, 5.4, and 7.1.7.
Should a patient decide to withdraw after administration of study drug, or should the investigator 
decide to withdraw the patient, all efforts will be made to complete and report all observations up 
to the time of withdrawal. A complete final evaluation at the time of the patient’s withdrawal 
should be made and an explanation given as to why the patient is withdrawing or being 
withdrawn from the study.
The reason for and date of withdrawal from study drug treatment and the reason for and date of 
withdrawal from the study must be recorded on the source documentation and transcribed onto 
the CRF. If a patient withdraws consent, every attempt will be made to determine the reason. If
the reason for withdrawal is an adverse event or a potentially clinically significant abnormal 
laboratory test result, monitoring will be continued at the discretion of the investigator (eg, until 
the event has resolved or stabilized, until the patient is referred to the care of a health care 
professional, or until a determination of a cause unrelated to the study drug or study procedure is 
made). The specific event or test result must be recorded on the source documentation and 
transcribed onto the CRF.
All protocol-specified procedures/assessments should be performed at the EOT/early withdrawal 
visit (see Table 1). Patients who withdraw from the study will be offered to enter the long-term

safety extension for the purpose of evaluating ADA approximately 7.5 months (225 days [the 
approximate equivalent of 5 half-lives]) after their last dose of study drug in this study. A patient 
should only be designated as lost to follow up if the site is unable to establish contact with the 
patient after 3 documented attempts via 2 different methods (phone, text, e-mail, certified letter, 
etc).

TREATMENT OF PATIENTS
5.1.
Drugs Administered During the Study
Following the baseline assessments, eligible patients will be randomly assigned with 
stratification based on gender, country, and baseline use of preventive migraine medication 
(yes, no) to receive monthly TEV-48125 at 225 mg, TEV-48125 at 675 mg followed by monthly 
placebo, or monthly placebo.
Study drug will be administered by qualified study personnel as sc injections approximately 
every 28 days for a total of 3 doses, as follows:

Patients randomized to receive monthly TEV-48125 at 225 mg will receive 225 mg of 
TEV-48125 as 1 active injection (225 mg/1.5 mL) and two 1.5-mL placebo injections 
at visit 2 and 225 mg of TEV-48125 as 1 active injection (225 mg/1.5 mL) at visits 3 
and 4. 

Patients randomized to receive TEV-48125 at 675 mg/placebo/placebo will receive 
675 mg of TEV-48125 as 3 active injections (225 mg/1.5 mL) at visit 2 and placebo 
as a single 1.5-mL injection at visits 3 and 4.

Patients randomized to receive placebo will receive three 1.5-mL placebo injections 
at visit 2 and a single 1.5-mL placebo injection at visits 3 and 4.
The 4-week (28-day) period will be determined relative to the planned dosing day provided the 
patient returns to the study center within the tolerance window (±3 days). If the patient returns to 
the study center more than 3 days late, then the 4-week period will be determined from the actual 
dosing day rather than the planned dosing day.
Individual, uniquely numbered visit kits containing 1 prefilled syringe with a staked 
27 G ½” needle will be provided.
At the time of each study visit, the IRT will be queried, and site personnel will retrieve and 
administer 1.5 mL from each syringe contained in the appropriately numbered kit(s).
Recommended sc injection sites follow the National Institutes of Health Patient Education 
Guidelines of June 2012, which are available in Appendix C of this document and in this 
website: http://www.cc.nih.gov/ccc/patient_education/pepubs/subq.pdf. The suggested sites of 
injection are back of upper arms, lower abdomen/belly/waistline, and front of thighs. Each of the 
injections at visit 2 should be given in a different location (eg, not in precisely the same place), 
and study staff member(s) responsible for administration of injections should inspect previous 
injection sites to ensure that they are free of bruising and tenderness and that proper rotation of 
sites is performed.
Study drug should be removed from the refrigerator and allowed to equilibrate at room 
temperature for 15 to 30 minutes before study drug administration.
A 1.5-mL volume from each syringe in each visit’s kit(s) must be injected sc for dosing to be 
considered complete. The total number of sc injections and their locations will be recorded for 
each dosing visit (visits 2, 3, and 4).

5.2.
Restrictions
Medications prohibited before and/or during the study are described in Section 5.3 and the 
exclusion criteria (Section 4.2). Restrictions in regard to pregnancy and required laboratory 
values are provided in the inclusion and exclusion criteria (Section 4.1 and Section 4.2, 
respectively). Restrictions in regard to sexual activity are also detailed in the inclusion and 
exclusion criteria (Section 4.1 and Section 4.2, respectively), and highly effective contraception 
methods are reviewed below.
Highly effective contraception methods include the following hormonal and other methods of 
birth control:

combined (estrogen and gestagen) oral contraceptives, hormone implants, hormone 
rings, contraceptive patch, and hormone injectables initiated at least 7 days before 
study drug administration

intrauterine device in place for a period of at least 2 months before study drug 
administration

barrier methods of contraception: condoms with spermicide for males, diaphragm 
with spermicide for females, and portio cap with spermicide for females

vasectomy for male partners of female patients
There were no additional restrictions in this study.
In addition, male patients may not donate sperm for the duration of the study and for 7.5 months 
after discontinuation of study drug.
5.3.
Prior and Concomitant Therapy or Medication
Any prior or concomitant therapy, medication, or procedure that a patient has had within 6 
months before study drug administration and up to the end of the study period will be recorded 
on the CRF. Generic or trade name, indication, and dosage will be recorded. In addition, 
migraine preventive medication that a patient took within 2 years before study drug 
administration will be recorded on the CRF. The sponsor will encode all therapy and medication 
according to the World Health Organization drug dictionary.
5.3.1.
Prior Medications and Therapeutic Failures of Migraine Preventives:
Details regarding excluded prior medications, including migraine preventive treatments, and 
therapeutic failures of migraine preventives are described in the exclusion criteria (Section 4.2).
5.3.2.
Concomitant Therapies and Medications
Up to 30% of patients will be allowed to remain on stable doses of no more than 1 preventive 
migraine medication for the duration of the study provided the medication has at least moderate 
evidence of efficacy as defined by guidelines (Silberstein et al 2012) and presented in 
Appendix A. Patients on preventive medication must be on a stable dose for at least 2 months of 
consecutive use prior to study entry. Alternatively, patients must have discontinued the 
preventive medication at least 5 half-lives prior to screening. Preventive migraine medications 
disallowed for at least 70% of patients for the duration of the study are presented in Appendix B.

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01

73
Patients will be allowed to use acute medication to treat acute migraine attacks, as needed.
All concomitant medications taken during the study, including over-the-counter medications, 
vitamins, or herbal or nutritional supplements, must be recorded with indication, daily dose, and 
start and stop dates of administration. All patients will be questioned about concomitant 
medication use at each visit.
5.4.
Procedures for Monitoring Patient Compliance
The investigator will be responsible for monitoring patient compliance. If the investigator or the 
sponsor determines that the patient is not in compliance with the study protocol, the investigator 
and the sponsor should determine whether the patient should be withdrawn. The IEC/IRB should 
be notified.
5.5.

ASSESSMENT OF EFFICACY
6.1.
Primary Efficacy Measure and Justification
The primary efficacy endpoint (and secondary and exploratory efficacy endpoints as well) will 
be derived from headache variables collected daily using an electronic headache diary device. 
Eligible patients will receive comprehensive training from site personnel on the use of the 
electronic headache diary device. Site personnel will also instruct patients on the requirement for 
timely and daily completion of the electronic diary.
On each day, the patient will be asked to record diary data for the previous 24-hour period. 
Patients may be asked about their performance at work, at school, and when doing household 
chores (ie, functional assessments). Patients who report headache on the previous day will 
answer questions about the headache (ie, the number of hours with headache, presence of 
associated symptoms, and use of acute migraine medications). Additional details regarding the 
questions patients will answer can be found in the electronic headache diary training manual.
If a patient fails to complete the diary for the preceding day, the patient will be prompted to enter 
the missed day’s information the next time he/she accesses the electronic diary provided no more 
than 48 hours have elapsed since completion of that day. If more than 48 hours have elapsed 
since completion of a diary day, the patient will not be allowed to enter diary information for that 
day, and it will be considered a missed day.
Rating of headache severity and duration of headache for each day will be completed in the 
electronic diary. 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 patient as 
follows:

mild headache

moderate headache

severe headache
Patients will also record whether photophobia, phonophobia, nausea, and vomiting are present, 
and they will record any migraine medications (name of drug, number of tablets/capsules, and 
the dose in milligrams per tablet/capsule) taken on each day.
6.2.
Migraine Disability Assessment
The MIDAS questionnaire is a 5-item instrument developed to assess headache-related disability
based on lost days of activity in 3 domains (work, household work, and nonwork) over the 
previous 3 months. The total of the scores of the first 5 questions is used for grading of disability, 
with scores of 0 to 5, 6 to 10, 11 to 20, and ≥21 interpreted as disability grades 1 (little or no 
disability), 2 (mild disability), 3 (moderate disability), and 4 (severe disability), respectively. It 
has been shown to be reliable and valid for migraine, with substantially higher scores in migraine 
cases than non-migraine cases (Stewart et al 1999a, Stewart et al 1999b).

Placebo-Controlled Study–Episodic Migraine

The PHQ is a 9-item questionnaire with each item corresponding to 1 criterion of the Diagnostic 
and Statistical Manual for Mental Disorders 4th 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 (Spitzer et al 1999). 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. The PHQ-2 and the PHQ-9 
are validated measures for detecting and monitoring depression, anxiety, and somatization 
(Kroenke et al 2010).
Patients will complete the PHQ-2 at baseline (visit 2) and the EOT visit (visit 5). If the PHQ-2 is 
positive (ie, a score of ≥3), patients will complete questions 3 through 9 (unique questions) of the 
PHQ-9.
6.4.
Migraine-Specific Quality of Life Questionnaire
The MSQOL, version 2.1 is a 14-item questionnaire that assesses the impact of migraine and 
migraine treatment on a patient’s quality of life during the previous 4 weeks, which has been 
shown to be a reliable and valid tool for use in CM and EM (Bagley et al 2012). 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.
Patients will complete the MSQOL at baseline (visit 2), visits 3 and 4, and the EOT visit 
(visit 5).
6.5.
EuroQol-5 Dimension Questionnaire
The EQ-5D-5L is a standardized questionnaire that assesses overall state of health. The 
EQ-5D-5L consists of 2 parts. In Part 1, patients rate their health state in 5 domains: mobility, 
self-care, usual activities, pain/discomfort, and mood, 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, patients 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.
Patients will complete the EQ-5D-5L at baseline (visit 2) and the EOT visit (visit 5).
6.6.
Patient Global Impression of Change Scale
The PGIC scale is a validated generic tool for assessment of overall change in the severity of 
illness following treatment. Patients 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 study on a 7-point scale where 1=no change (or condition has got worse);

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
76
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.
Patients will complete the PGIC scale before study drug administration at visits 3 and 4 and at 
the EOT visit (visit 5).
6.7.
Work Productivity and Activity Impairment Questionnaire
The generic version of the WPAI questionnaire measures the overall effect of health on 
productivity at work and daily activities. The specific health problems version of the WPAI 
questionnaire 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, 1 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) (Reilly et al 1993). 
Patients will complete the WPAI questionnaire at baseline (visit 2) and at the EOT visit (visit 5).

ASSESSMENT OF SAFETY
In this study, safety will be assessed by qualified study personnel by evaluating the following: 
reported adverse events, clinical laboratory test results, vital signs measurements, 12-lead ECG 
findings, physical examination findings (including body weight measurements), eC-SSRS scores,
local injection site assessments, and concomitant medication usage.
7.1.
Adverse Events
7.1.1.
Definition of an Adverse Event
An adverse event is any untoward medical occurrence in a patient administered a pharmaceutical 
product, regardless of whether it has a causal relationship with this treatment.
In this study, any adverse event occurring after the clinical study patient has signed the informed 
consent form should be recorded and reported as an adverse event.
An adverse event can, therefore, be any unfavorable and unintended physical sign, symptom, or 
laboratory parameter that develops or worsens in severity during the course of this study or a
significant worsening of the disease under study or of any concurrent disease, whether or not 
considered related to the study drug. A new condition or the worsening of a pre-existing 
condition will be considered an adverse event. Stable chronic conditions (such as arthritis) that 
are present before study entry and do not worsen during this study will not be considered adverse 
events.
Accordingly, an adverse event can include any of the following:

intercurrent illnesses

physical injuries

events possibly related to concomitant medication

significant worsening (change in nature, severity, or frequency) of the disease under 
study or other pre-existing conditions (Note: A condition recorded as pre-existing that 
is intermittently symptomatic [eg, headache] and that occurs during this study should 
be recorded as an adverse event.)

drug interactions

events occurring during diagnostic procedures of this study or during any follow-up 
period of this study

laboratory or diagnostic test abnormalities that result in the withdrawal of the patient 
from the study, are associated with clinical signs and symptoms or a serious adverse 
event, require medical treatment or further diagnostic work-up, or are considered by 
the investigator to be clinically significant (Note: Abnormal laboratory test results at 
the screening visit that preclude a patient from entering the study or receiving study 
drug are not considered adverse events.)

all events of possible drug-induced liver injury with hyperbilirubinemia (defined as 
AST or ALT ≥3 times the ULN, plus either total bilirubin ≥2 times the ULN or INR

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
78
>1.5) or Hy’s Law events require immediate study treatment cessation and reporting 
as a serious adverse event. Refer to Appendix E for guidance regarding monitoring 
patients with elevated liver function tests.
Migraine exacerbations, including acute headache, requiring headache medications will be 
collected as part of the efficacy assessment in this study. Migraine exacerbations (including acute 
headache) should be recorded as an adverse event only if the presentation and/or outcome is 
more severe than would typically be expected from the normal course of the disease in a 
particular patient or if they are severe enough to require hospitalization of the patient, in which 
case they are recorded as serious adverse events.
7.1.2.
Recording and Reporting Adverse Events
For adverse event recording, the study period is defined for each patient as the time period from 
signature of the informed consent form through completion of visit 5 or the early withdrawal 
visit for patients who withdraw from the study for any reason. Adverse events will be collected 
at each visit via adverse event inquiry.
All adverse events that occur during the defined study period must be recorded on the source 
documentation and transcribed onto the CRF, regardless of the severity of the event or judged 
relationship to the study drug. For serious adverse events, the serious adverse event form must be 
completed, and the serious adverse event must be reported immediately (see Section 7.1.5.3.1).
The investigator does not need to actively monitor patients for adverse events once the study has 
ended. Serious adverse events occurring after the defined study period should be reported to the 
sponsor if the investigator becomes aware of them, following the procedures described in 
Section 7.1.5.3.1.
At each contact with the patient, the investigator or designee must question the patient about 
adverse events by asking an open-ended question such as, “Have you had any unusual symptoms 
or medical problems since the last visit? If yes, please describe.” All reported or observed signs 
and symptoms will be recorded individually, except when considered manifestations of a 
medical condition or disease state. A precise diagnosis will be recorded whenever possible. 
When such a diagnosis is made, all related signs, symptoms, and any test findings will be 
recorded collectively as a single diagnosis on the CRF and, if it is a serious adverse event, also 
on the serious adverse event form.
The clinical course of each adverse event will be monitored at suitable intervals until it resolves, 
stabilizes, or returns to baseline; until the patient is referred for continued care to a another health 
care professional; or until a determination of a cause unrelated to the study drug or study 
procedure is made.
The onset and end dates, duration (in case of adverse event duration of less than 24 hours), action 
taken regarding study drug, treatment administered, and outcome for each adverse event must be 
recorded on the source documentation and transcribed onto the CRF.
The relationship of each adverse event to study drug and study procedures, and the severity and 
seriousness of each adverse event, as judged by the investigator, must be recorded, as described 
below.

Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
79
7.1.3.
Severity of an Adverse Event
The severity of each adverse event must be recorded as 1 of the choices on the following scale:
Mild: 
No limitation of usual activities
Moderate: Some limitation of usual activities
Severe: 
Inability to carry out usual activities
7.1.4.
Relationship of an Adverse Event to the Study Drug
The relationship of an adverse event to the study drug is characterized as follows:
Term
Definition
Clarification
No reasonable 
possibility
(not related)
This category applies to adverse 
events that, after careful 
consideration, are clearly due to 
extraneous causes (disease, 
environment, etc) or to adverse 
events that, after careful medical 
consideration at the time they are 
evaluated, are judged to be unrelated 
to the study drug.
The relationship of an adverse event may be considered 
“no reasonable possibility” if it is clearly due to 
extraneous causes or if at least 2 of the following apply:

It does not follow a reasonable temporal sequence 
from the administration of the study drug.

It could readily have been produced by the patient’s 
clinical state, environmental, or toxic factors or other 
modes of therapy administered to the patient.

It does not follow a known pattern of response to the 
study drug. 

It does not reappear or worsen when the study drug is 
re-administered. 
Reasonable 
possibility
(related)
This category applies to adverse 
events for which, after careful 
medical consideration at the time 
they are evaluated, a connection with 
the study drug administration cannot 
be ruled out with certainty.
The relationship of an adverse event may be considered 
“reasonable possibility” if at least 2 of the following 
apply:

It follows a reasonable temporal sequence from 
administration of the study drug.

It cannot be reasonably explained by the known 
characteristics of the patient’s clinical state, 
environmental, or toxic factors or other modes of 
therapy administered to the patient.

It disappears or decreases on cessation or reduction in 
dose. There are important exceptions when an 
adverse event does not disappear upon 
discontinuation of the study drug, yet a drug 
relationship clearly exists.

It follows a known pattern of response to the study 
drug.

7.1.5.
Serious Adverse Events
7.1.5.1.
Definition of a Serious Adverse Event
A serious adverse event is an adverse event occurring at any dose that results in any of the 
following outcomes or actions:

death

a life-threatening adverse event (ie, the patient was at immediate risk of death from 
the event as it occurs); does not include an event that, had it occurred in a more severe 
form, might have caused death

inpatient hospitalization or prolongation of existing hospitalization, which means that 
hospital inpatient admission and/or prolongation of hospital stay were required for 
treatment of an adverse event, or that they occurred as a consequence of the event. 
Hospitalizations scheduled prior to study entry will not be considered serious adverse 
events, unless there was worsening of the pre-existing condition during the patient’s 
participation in this study

persistent or significant disability or incapacity (refers to a substantial disruption of
one’s ability to conduct normal life functions)

a congenital anomaly/birth defect

an important medical event that may not result in death, be life-threatening, or require 
hospitalization, but may jeopardize the patient and may require medical intervention
to prevent one of the outcomes listed in this definition. Examples of such events are 
intensive treatment in an emergency room or at home for allergic bronchospasm, 
blood dyscrasias or convulsions that do not result in hospitalization, or the 
development of drug dependency or drug abuse. Note: Any suspected transmission of 
an infectious agent via a medicinal product is considered an important medical event.
An adverse event that does not meet any of the criteria for seriousness listed above will be 
regarded as a nonserious adverse event.
7.1.5.2.
Expectedness
A serious adverse event that is not included in the Adverse Reaction section of the relevant 
reference safety information by its specificity, severity, outcome, or frequency is considered an 
unexpected adverse event. The reference safety information for this study is the Investigator’s 
Brochure.
The sponsor’s Pharmacovigilance Department will determine the expectedness for all serious 
adverse events.
For the purpose of SUSAR reporting, the version of the reference safety information document at 
the moment of the occurrence of the SUSAR applies.

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
81
7.1.5.3.
Reporting a Serious Adverse Event
7.1.5.3.1. Investigator Responsibility
To satisfy regulatory requirements, all serious adverse events (as described in Section 7.1.5.1) 
that occur during the defined study period, regardless of judged relationship to treatment with the 
study drug, must be reported to the sponsor by the investigator. The event must be reported
within 24 hours of when the investigator learns about it. Completing the serious adverse event 
form and reporting the event must not be delayed, even if not all the information is available.
The investigator does not need to actively monitor patients for adverse events once this study has
ended. Serious adverse events occurring in a patient after the defined study period should be 
reported to the sponsor if the investigator becomes aware of them.
The serious adverse event form should be sent to the local safety officer (LSO) or other 
designated personnel (a contract research organization [CRO] in a country without a sponsor 
LSO; contact information is in the Clinical Study Personnel Contact Information section); the 
LSO will forward the report to the sponsor’s Global Patient Safety & Pharmacovigilance 
Department.
The following information should be provided to record the event accurately and completely:

study number

investigator and investigational center identification

patient number

onset date and detailed description of adverse event

investigator’s assessment of the relationship of the adverse event to the study drug 
(no reasonable possibility, reasonable possibility)
Additional information may include the following:

age and sex of patient

date of 1st dose of study drug

date and amount of last administered dose of study drug

action taken

outcome, if known

severity

explanation of assessment of relatedness

concomitant therapy (including doses, routes, and regimens) and treatment of the 
event

pertinent laboratory or other diagnostic test data

medical history

results of dechallenge/rechallenge, if known

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
82

for an adverse event resulting in death:

cause of death (whether or not the death is related to study drug)

autopsy findings (if available)
Each report of a serious adverse event will be reviewed and evaluated by the investigator and the 
sponsor to assess the nature of the event and the relationship of the event to the study drug, study 
procedures, and underlying disease.
Additional information (follow-up) about any serious adverse event unavailable at the initial 
reporting should be forwarded by the investigational center within 24 hours of when it becomes 
known to the same address as the initial report.
For all countries, the sponsor’s Global Patient Safety & Pharmacovigilance Department will 
distribute the Council for International Organizations of Medical Sciences form/extensible 
markup language file to the LSO and/or CRO for local submission to the regulatory authorities, 
IEC/IRBs, and investigators, according to regulations. The investigator is responsible for 
ensuring that the IRB/IEC is also informed of the event, in accordance with local regulations.
Blinding will be maintained for the people who are involved directly in the study. Therefore, in 
case of a SUSAR, only the LSO or CRO personnel involved with safety regulatory submissions 
will receive the unblinded report for regulatory submission; the others will receive a blinded 
report.
Note: Although pregnancy is not a serious adverse event, the process for reporting a pregnancy is 
the same as that for reporting a serious adverse event, but using the pregnancy form (see 
Section 7.2).
7.1.5.3.2. Sponsor Responsibility
If a serious unexpected adverse event is believed to be related to the study drug or study 
procedures, the sponsor will take appropriate steps to notify all investigators participating in 
sponsored clinical studies of TEV-48125 and the appropriate regulatory authorities (and 
IEC/IRB, if appropriate).
In addition to notifying the investigators and regulatory authorities (and IEC/IRB, if appropriate), 
other measures may be required, including the following:

altering existing research by modifying the protocol

discontinuing or suspending the study

altering the process of informed consent by modifying the existing consent form and 
informing current study participants of new findings

modifying listings of expected toxicities to include adverse events newly identified as 
related to TEV-48125
7.1.6.
Protocol-Defined Adverse Events of Special Interest
The following are considered protocol-defined adverse events to be sent to the sponsor’s Global 
Patient Safety and Pharmacovigilance Department for evaluation: ophthalmic adverse events of 
at least moderate severity, events of possible drug-induced liver injury (AST or ALT ≥3 × the 

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
83
ULN, total bilirubin ≥2 × the ULN or INR >1.5), Hy’s Law events, or events of suspected 
anaphylaxis and severe hypersensitivity reactions. Severe hypersensitivity reactions will be 
monitored using the diagnostic criteria for anaphylaxis as outlined by the 2006 Joint National 
Institute of Allergy and Infectious Disease/Food Allergy and Anaphylaxis Network Second 
Symposium on Anaphylaxis (Sampson et al, 2006 [also see Appendix F]). 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.
The process for reporting a protocol-defined adverse event is the same as that for reporting a 
serious adverse event (see Section 7.1.5.3). Protocol-defined adverse events for reporting to 
Pharmacovigilance Department can be either serious or nonserious according to the criteria 
outlined in Section 7.1.5.
7.1.7.
Withdrawal Due to an Adverse Event
Any patient who experiences an adverse event may be withdrawn from the study or from study 
drug at any time, at the discretion of the investigator. If a patient is withdrawn because of an 
adverse event, both the adverse events page and termination page of the CRF will be completed 
at that time.
The patient will be monitored at the discretion of the investigator (eg, until the event has 
resolved or stabilized, until the patient is referred to the care of a health care professional, or 
until a determination of a cause unrelated to the study drug or study procedure is made). The 
investigator must inform the clinical project physician/clinical leader as soon as possible of all 
patients who are being considered for withdrawal due to adverse events. Additional reports must 
be provided when requested.
If a patient is withdrawn from the study or study drug for multiple reasons that include adverse 
events, the termination page of the CRF should indicate that the withdrawal is related to an 
adverse event. An exception to this requirement will be the occurrence of an adverse event that, 
in the opinion of the investigator, is not severe enough to warrant discontinuation but requires the 
use of a prohibited medication, thereby requiring discontinuation of the patient. In such a case, 
the reason for discontinuation would be the need to take a prohibited medication, not the adverse 
event.
7.1.8.
Overdose of Study Drug
Any dose of study drug (whether the investigational product or placebo), whether taken 
intentionally or unintentionally, in excess of that prescribed must be immediately reported to the 
sponsor. When the identification of the study drug must be known, the investigator must follow 
the procedures outlined in Section 3.8.
7.1.9.
Protocol Deviations Because of an Adverse Event
If a patient experiences an adverse event or medical emergency, departures from the protocol 
may be allowed on a case-by-case basis. After stabilization and/or treatment has been 
administered to ensure patient safety, the investigator or other physician in attendance must 
contact the individual identified in the Clinical Study Personnel Contact Information section of 
this protocol as soon as possible to discuss the situation. The investigator, in consultation with 
the sponsor, will decide whether the patient should continue to participate in the study.

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
84
7.2.
Pregnancy
All pregnancies of women participating in the study that occur during the study, or within
7.5 months after the last administration of TEV-48125, are to be reported immediately to the 
individual identified in the Clinical Study Personnel Contact Information section of this protocol, 
and the investigator must provide the LSO and/or CRO with the pregnancy form. The process for 
reporting a pregnancy is the same as that for reporting a serious adverse event (see 
Section 7.1.5.3).
Any female patient becoming pregnant during the study will discontinue the study drug. All 
patients who become pregnant will be monitored for the outcome of the pregnancy (including 
spontaneous or voluntary termination). If the pregnancy continues to term, the outcome (health 
of the infant up to 8 weeks of age), including details of birth and presence or absence of any birth 
defect, congenital abnormalities, or maternal and newborn complications, will be reported to the 
sponsor. Any complication of pregnancy during the study and any complication of pregnancy 
that the investigator becomes aware of after termination from the study will be reported as an 
adverse event or serious adverse event, as appropriate.
If the pregnancy does not continue to term, 1 of the following actions will be taken:

For a spontaneous abortion, report as a serious adverse event.

For an elective abortion due to developmental anomalies, report as a serious adverse 
event.

For an elective abortion not due to developmental anomalies, report on the pregnancy 
form; do not report as an adverse event.
For pregnancies of partners of men participating in the study, the Teva Pharmacovigilance 
Department will determine the procedure to appropriately follow up after notification as 
described above. All partners who become pregnant and provide appropriate consent to the Teva 
Pharmacovigilance Department will be monitored to the completion or termination of the 
pregnancy.
7.3.
Clinical Laboratory Tests
All clinical laboratory test results outside of the reference range will be interpreted by the 
investigator as belonging to 1 of the following categories:

abnormal but not a clinically significant worsening from baseline

abnormal and a clinically significant worsening from baseline
A laboratory test result that has significantly worsened (according to medical judgment) from the 
baseline result will be recorded on the source documentation, transcribed onto the CRF as an 
adverse event, and monitored as described in Section 7.1.2. An adverse event includes a 
laboratory or diagnostic test abnormality (once confirmed by repeat testing) that results in the 
withdrawal of the patient from the study, the temporary or permanent cessation of treatment with 
study drug, or medical treatment or further diagnostic work-up.
In addition, potentially clinically significant values will be predefined by the sponsor for selected 
laboratory parameters and will be detailed in the statistical analysis plan.

Other Clinical Laboratory Tests
7.3.5.1.
Human Chorionic Gonadotropin Tests
Serum β-HCG tests will be performed for women of childbearing potential at screening (visit 1), 
and urine β-HCG tests will be performed for women of childbearing potential at visits 2 
through 5. Any patient who becomes pregnant during the study will be withdrawn. Procedures 
for reporting the pregnancy are provided in Section 7.2. 
7.3.5.2.
Follicle-Stimulating Hormone Tests
Postmenopausal women will have an FSH test at screening (visit 1).
7.4.
Vital Signs
Vital signs (pulse, systolic and diastolic blood pressure, body temperature, and respiratory rate) 
will be measured before other assessments (eg, blood draws and administration of 
questionnaires) at the time points detailed in Table 1.
Before pulse and blood pressure are measured, the patient must be in a supine or 
semi-erect/seated 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 patient. For any abnormal vital sign 
finding, the measurement should be repeated as soon as possible. Any vital sign value that is 
judged by the investigator as a clinically significant change (worsening) from a baseline value 
will be considered an adverse event, recorded on the source documentation and transcribed onto 
the CRF, and monitored as described in Section 7.1.2.
In addition, potentially clinically significant values may be predefined by the sponsor for 
selected vital signs (see Section 9.7.2) and, if so, will be documented in the statistical analysis 
plan or other relevant documents (eg, medical monitoring plan).
7.5.
Electrocardiography
Twelve-lead ECGs will be conducted before other assessments (eg, blood draws and 
administration of questionnaires) at the time points detailed in Table 1. The ECGs should be 
performed after the patient has been supine for at least 5 minutes. The ECGs will be performed 
in triplicate.
A qualified physician at a central diagnostic center will be responsible for interpreting the ECG. 
ECGs should be performed and transmitted according to the central ECG reading instructions 
provided in the ECG user manual. ECG equipment will be provided to all clinical sites.

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
88
Although the ECG interpretation will be performed centrally, the clinical evaluation remains 
under the Investigator’s responsibility.
The ECG will be evaluated by the Investigator at the time of recording (signed and dated), and 
the printout should be kept in the source documentation file. When potentially clinically 
significant findings are detected by the Investigator, a cardiologist should be consulted for a 
definitive interpretation. All communications and diagnoses should be filed in the source 
documentation file. The Investigator’s interpretation will be recorded in the CRF regardless of 
the central reading interpretation. Any abnormal findings assessed by the Investigator as 
clinically significant should be recorded in the relevant CRF modules (eg, adverse event, medical 
history).
Objective alerts are predefined as described in the central ECG reading manual. In these cases, 
the site and the sponsor will be informed immediately.
Any unscheduled ECGs must also be submitted for central ECG reading.
Any ECG finding that is judged by the investigator as a potentially clinically significant change 
(worsening) compared with a baseline value will be considered an adverse event, recorded on the 
source documentation and transcribed onto the CRF, and monitored as described in 
Section 7.1.2.
7.6.
Physical Examinations
Physical examinations, including height (to be obtained at the screening visit only) and weight 
will be performed at the time points detailed in Table 1.
A complete physical examination will include the following organ systems: general appearance; 
head, eyes, ears, nose, and throat; chest and lungs; heart; abdomen; musculoskeletal; skin; lymph 
nodes; and neurological. Any physical examination finding that is judged by the investigator as a 
potentially clinically significant change (worsening) compared with a baseline value will be 
considered an adverse event, recorded on the CRF, and monitored as described in Section 7.1.2.
7.7.
Electronic Columbia-Suicide Severity Rating Scale
The eC-SSRS will be used to assess the patient’s suicidal ideation (severity and intensity) and 
behavior (Posner et al 2011). The eC-SSRS Baseline/Screening version will be completed by the 
patient at visit 2, and the eC-SSRS Since Last Visit version will be completed by the patient at 
all other time points, as described in Table 1. Any positive findings on the eC-SSRS Since Last 
Visit version requires evaluation by a physician or doctoral-level psychologist.
7.8.
Concomitant Therapy or Medication
Concomitant therapy or medication usage will be monitored throughout the study. Details of 
prohibited medications are found in Section 5.3. 
7.9.
Immunogenicity
Blood samples for serum ADA assessment will be collected at visits 2, 3, and the EOT/early 
withdrawal visit. Only the samples from TEV-48125-treated patients will be analyzed for ADA. 
Blood samples for ADA assessment will also be collected upon observation of any severe

hypersensitivity reaction (eg, anaphylaxis). See Appendix F for the clinical criteria for 
diagnosing anaphylaxis. Bioanalytical personnel should be made aware of any anaphylaxis 
occurrence as soon as possible in case an anti-TEV-48125 immunoglobulin E assay is required.
7.10.
Injection Site Assessments
Injection site assessments will be performed immediately and 1 hour after administration of each 
dose of study drug (Table 1). The injection site(s) will be assessed for erythema, induration, 
ecchymosis, and pain, and severity will be graded according to the following criteria:

Injection-site erythema, injection-site induration, and injection-site ecchymosis will 
be graded according to measurements: absent, 5 mm 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 measured as summarized in Table 3.
Table 3:
Severity of Pain Scale for Injection Site Assessments

If a patient has severe injection site induration, erythema, and/or ecchymosis and/or grade 3 
(severe) or grade 4 (worst possible) injection site pain at 1 hour after completion of study drug 
administration, the patient will be reassessed at 3 hours after study drug administration and 
hourly thereafter until the reaction/pain is of moderate or less severity.
Appropriate treatment may be provided if necessary, in which case it must be recorded as 
concomitant medication.
Injection site reactions will also be recorded as adverse events as described in Section 7.1.
7.11.
Methods and Timing of Assessing, Recording, and Analyzing Safety 
Data
All adverse events will be reviewed on a periodic basis by the clinical project physician/medical 
monitor according to the safety monitoring plan (eg, scheduled safety reviews for TEV-48125)
as interim/preliminary safety databases become available. Safety data will additionally be 
evaluated periodically and ad hoc (if necessary) in the Product Safety Group.
Methods and timing of assessing safety data are discussed in Section 3.14. Procedures for 
recording safety data are discussed in Section 13.1 and methods of analyses are discussed in 
Section 9.7.2.

ASSESSMENT OF PHARMACOKINETICS/ BIOMARKERS/ 
IMMUNOGENICITY
8.1.
Pharmacokinetic Variables
Sampling for pharmacokinetics will be sparse. Thus, the TEV-48125 pharmacokinetic samples 
will be analyzed using a population pharmacokinetic approach and will be reported separately to 
the clinical study report.
Samples from patients who receive active study drug will be analyzed for TEV-48125 using a 
validated method. Samples from patients who receive placebo will not be analyzed.
8.1.1.
Specimen Sampling and Handling
Blood samples (4 mL) will be collected via venipuncture or indwelling catheter at the time points 
detailed in Table 1 for plasma concentration measurements of TEV-48125.
The dates and times of study drug administration and the date and time of each pharmacokinetic 
sample will be recorded on the source documentation and transcribed onto the CRF.
For plasma collection, samples will be collected into dipotassium EDTA collection tubes, 
inverted slowly 6 to 8 times to mix the contents, and placed on water/ice (~4°C). Blood samples 
will be centrifuged (1500g, ~10 minutes, 2°C to 6°C) between 5 minutes and 1 hour after 
sampling. If a refrigerated centrifuge is not available, samples should be chilled before 
centrifugation. Other measures should be taken as appropriate to prevent samples from heating 
significantly during centrifugation. Separated plasma will be transferred in approximately equal 
portions into 2 labeled, 2-mL polypropylene tubes (sets A and B).
Labels for samples should include study number, patient number, period, nominal collection 
time, set (A or B), and indication that they are pharmacokinetic samples. Samples will be stored 
at a temperature within the range of -70°C ±20°C in an upright position until they are shipped to 
the central laboratory.
8.1.2.
Shipment and Analysis of Samples
Plasma samples for all patients will be shipped frozen on dry ice from the investigational center 
to the central laboratory, where they will be stored until shipment to the sponsor or its designee
for analysis.

Set A samples will be transported (frozen) with a temperature data logger, by 
next-day courier, to the central laboratory.

Set B samples will either be sent to the same laboratory as that for set A on a 
subsequent day, by next-day courier, or be retained at the investigational center until 
the study is completed and the clinical study report has been issued (unless shipment 
to another facility is requested by the sponsor).
Samples will be analyzed using a validated method. Timing of the initiation of sample analysis 
will be determined by the Teva Pharmaceuticals bioanalytical representative responsible for the 
bioanalysis. Refer to the laboratory manual for additional details.

Immunogenicity Testing
8.2.1.
Blood Sampling and Handling
Samples from patients who receive active study drug will be analyzed for ADA using a validated 
method. Samples from patients who receive placebo will not be analyzed.
Blood samples (5 mL) will be collected via venipuncture or indwelling catheter at the time points 
detailed in Table 1 for immunogenicity testing.
For serum collection, samples will be collected into Vacutainer tubes containing no 
anticoagulant, and allowed to set at room temperature less than 30 minutes to allow for serum 
separation to occur. Samples will then be centrifuged (1500g, approximately 10 minutes, 2°C to 
6°C). If a refrigerated centrifuge is not available, samples should be chilled before centrifugation. 
Other measures should be taken as appropriate to prevent samples from heating significantly 
during centrifugation. Separated serum will be transferred in approximately equal portions into 
2 labeled, 2-mL polypropylene tubes (sets A and B).
Sample labels should include study number, patient number, period, nominal collection time, set 
(A or B), and indication that they are ADA samples. Serum samples will be stored at a 
temperature within the range of -70°C ± 20°C in an upright position until they are shipped to the 
central laboratory.
8.2.2.
Shipment and Analysis of Samples
Serum samples for all patients will be shipped frozen on dry ice from the investigational center 
to the central laboratory, where they will be stored until shipment to the sponsor or its designee
for analysis.

Set A samples will be transported (frozen) with a temperature data logger, by 
next-day courier, to the central laboratory.

Set B samples will either be sent to the same laboratory as that for set A on a 
subsequent day, by next-day courier, or be retained at the investigational center until 
the study is completed and the clinical study report has been issued (unless shipment 
to another facility is requested by the sponsor).
Samples will be analyzed using an appropriate validated method. Timing of the initiation of 
sample analysis will be determined by the Teva Pharmaceuticals department representative 
responsible for the bioanalysis. Refer to the laboratory manual for additional details.
8.3.
Assessment of Exploratory Biofluid Biomarkers
Biomarkers are defined as biological substances that monitor physiological effects, assess drug 
activity, and predict clinical outcome, safety, and response to therapy.
Calcitonin gene-related peptide-containing nerve fibers are prevalent in bone tissue and have 
been hypothesized to be important in the regulation of bone metabolism, response to bone injury,
and the perception of bone pain. In vitro, CGRP is anabolic to osteoblasts and can inhibit 
maturation to osteoclasts. Preclinical studies suggest CGRP antagonism may have benefit in 
osteoarthritis (Benschop et al 2014) and bone-related pain. In the current study, exploratory 

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
92
analysis may be conducted on blood (serum, plasma, and RNA) and urine biomarkers, 
extracellular matrix turnover, bone formation, and bone resorption.
In preclinical models, CGRP can promote angiogenesis in ischemia, capsaicin-induced synovitis, 
and neovascularization of tumors. Exploratory analysis will be conducted on 
endothelial/angiogenic markers to determine if TEV-48125 alters angiogenic markers.
Calcitonin gene-related peptide is known to act directly on macrophage and dendritic cells by 
inhibiting them from producing inflammatory cytokines and presenting antigens to T cells. It has 
been hypothesized that CGRP may act as a regulator of the innate immune response. Exploratory 
analysis will be conducted on inflammatory endpoints in blood to examine effects of TEV-48125 
in patients with migraine.
Based on the known biology of CGRP’s mechanism of action, biomarker assessment will 
potentially include markers of bone remodeling, inflammation, and angiogenesis. Multiplex 
immunoassay panels will be applied to measure changes in urine, serum, plasma, and RNA
biomarkers.
The planned biomarker analysis will be detailed in a separate document, which may be updated 
at a later stage before the analysis to allow updating with new scientific information.
8.3.1.
Pharmacogenomic Assessment
A blood sample (6 mL) will be collected from each patient who signs the separate informed 
consent form for pharmacogenomic assessment during this study. Pharmacogenomic assessment 
potentially includes the association analysis of both known and unknown DNA and RNA genetic 
variations. In the current study, known CGRP and migraine-associated genes will be examined to 
determine their association with clinical treatment responses to study drug 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). The current list of 
genes with polymorphisms associated with either CGRP target engagement or migraine 
mechanism of action includes CALCA, CALCB, CALCRL, CRCP, RAMP, PRDM16, AJAP1, 
TSPAN2, MEF2D, TRPM8, TGFBR2, PHACTR1, FHL5, C7orf10, MMP16, ASTN2, LRP1, 
APOA1BP, TBC1D7, FUT9, STAT6, ATP5B, and MTHFR (Anttila et al 2013). The final list of 
genes that may be investigated may be edited at a later time before the analysis to allow updating 
with new scientific information. Genetic analysis could also include sequencing of the whole 
genome and/or RNA transcripts, if required.
Pharmacogenomic assessment will be performed based on study results. Samples will be used for 
investigations related to headache, indications where CGRP pathways are implicated, and 
indications that may be associated with the risk of headache or those that are common 
comorbidities associated with headache and/or response to study drug or related investigational 
drugs.
8.3.2.
Specimen Sampling and Handling
Blood samples (a total of 18.5 mL; 6 mL each for plasma and serum and 6.5 mL for RNA 
[PAXgene]) will be collected via venipuncture or indwelling catheter at the time points detailed 
in Table 1 for serum, plasma, and RNA biomarker measures. Urine will be collected in parallel 
with blood collection. In addition, a 6-mL whole blood sample will be collected at baseline for 

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
93
DNA. Details for processing and handling of each type of biomarker sample will be outlined in 
the laboratory manual.
All blood and urine tubes will be labeled with the patient coded number. Following DNA 
extraction from pharmacogenomic sample, the sample will be labeled with a new code 
(ie, double coding), so that genetic data will not be recorded having a patient number.
Samples will be stored for a period of up to 15 years from the last patient last visit in the main 
study and then destroyed.
8.3.3.
Shipment and Analysis of Samples
Biomarker samples for serum, plasma, RNA, and urine will be stored at –70°C and sent to the 
central laboratory on dry ice, per instructions in the laboratory manual. Sample labels should 
include study number, patient randomization number, visit code, collection date and time, and 
indication that they are biomarker samples. Shipments should be made as specified in laboratory 
manual. An electronic file containing sample demographics will be e-mailed to the respective 
biomarker laboratory and the sponsor’s biomarker representative for each shipment.
Following DNA extractions of whole blood, the samples will be stored at –70°C and labeled 
with a new code (ie, double coding), so that genomic data will not be recorded with a patient 
number. Data will be kept confidential and stored separately.
The biomarker sample analyses will be performed if and when required. Since new techniques 
continue to be developed, the method and laboratory that will be recommended for the future 
biomarker analysis cannot be anticipated.

Methods and Timing of Assessing, Recording, and Analyzing Clinical 
Pharmacology Data
Methods and timing of assessing clinical pharmacology data are discussed in Section 3.14. 
Procedures for recording clinical pharmacology data are discussed in Section 13.1, and methods 
of analyses are discussed in Section 9.5.4.

STATISTICS
This study is a Phase 3, multicenter, randomized, double-blind, placebo-controlled parallel-group 
study to assess the efficacy and safety of 2 dose regimens of sc administration of TEV-48125 
compared with placebo for preventive treatment of EM. Eligible patients will be randomized in a 
1:1:1 ratio to receive monthly TEV-48125 at 225 mg, TEV-48125 at 675 mg followed by 
monthly placebo, or monthly placebo. Randomization will be stratified by gender, country, and
baseline preventive medication use (yes, no).
9.1.
Sample Size and Power Considerations
A total of 768 patients are planned to be randomized in this study to have 675 completers 
(225 completers per treatment group); a 12% drop-out rate is anticipated. A sample size of 
675 patients (ie, 225 evaluable patients completing the study per treatment group) will provide 
90% power to detect a 1.6 difference in migraine days between an active arm and placebo arm at 
an alpha level of 0.05, assuming a common standard deviation (SD) of 5.2 days.
9.2.
Analysis Sets
9.2.1.

The intent-to-treat (ITT) analysis set will include all randomized patients. In this population, 
treatment will be assigned based on the treatment to which patients are randomized, regardless of 
which treatment they actually received.
9.2.2.
Safety Analysis Set
The safety analysis set will include all patients who receive at least 1 dose of study drug. In this 
population, treatment will be assigned based upon the treatment patients actually receive, 
regardless of the treatment to which they are randomized.

Primary Efficacy Analysis
The primary efficacy endpoint, the mean change from baseline (28-day run-in period) in the 
monthly average number of migraine days during the 12-week period after the 1st dose of study 
drug, will be analyzed using an analysis of covariance method. The model will include treatment, 
gender, country, and baseline preventive medication use as fixed effects, and baseline number of 
migraine days and years since onset of migraines as covariates. Ninety-five percent confidence 
intervals will be constructed for the least squares mean differences between each TEV-48125 
group and the placebo group. A hierarchical procedure will be used to control type 1 error rate. 
9.5.4.2.
Sensitivity Analysis
Sensitivity analysis may be conducted to explore the impact of missing data in the primary 
efficacy analysis.
9.5.4.3.
Secondary Efficacy Analysis
The same analysis used for the primary efficacy endpoint will be performed for the secondary 
efficacy endpoints. For the proportion of responders defined as 50% or more reduction from 
baseline in the monthly average number of migraine days, Cochran-Mantel-Haenszel test will be 
used.
9.5.4.4.
Exploratory Efficacy Analysis
The same analyses used for the primary and secondary efficacy endpoints will be performed for 
the exploratory efficacy endpoints, as appropriate.
9.6.
Multiple Comparisons and Multiplicity
A fixed-sequence (hierarchical) testing procedure will be implemented to control the type 1 error 
rate at 0.05. The sequence of comparisons will be described in detail in the statistical analysis 
plan.

9.7.2.
Safety Analysis
All adverse events will be coded using the Medical Dictionary for Regulatory Activities. Each 
patient will be counted only once in each preferred term or system organ class category for the 
analyses of safety. Summaries will be presented for all adverse events (overall and by severity), 
adverse events determined by the investigator to be related to study treatment (ie, reasonable 
possibility; see Section 7.1.4) (defined as related or with missing relationship) (overall and by 
severity), serious adverse events, and adverse events causing withdrawal from the study. Patient 
listings of serious adverse events and adverse events leading to withdrawal will be presented.
Injection site erythema, induration, ecchymosis, and pain will be assessed as described in 
Section 7.9, and findings will be listed and summarized.
Changes in laboratory and vital signs measurement data will be summarized descriptively. All 
values will be compared with prespecified boundaries to identify potentially clinically significant 
changes or values, and such values will be listed.
The use of concomitant medications will be summarized by therapeutic class using descriptive 
statistics. Concomitant medications will include all medications taken while the patient is treated 
with study drug.
Safety data will be summarized descriptively overall and by treatment group. For continuous 
variables, descriptive statistics (n, mean, SD, median, minimum, and maximum) will be provided 
for actual values and changes from baseline to each time point. For categorical variables, patient 
counts and percentages will be provided. Descriptive summaries of serious adverse events, 
patient withdrawals due to adverse events, and potentially clinically significant abnormal values

DIRECT ACCESS TO SOURCE DATA/DOCUMENTS
The medical experts, study monitors, auditors, IEC/IRB, and health authority inspectors (or their 
agents) will be given direct access to source data and documentation (eg, medical charts/records, 
laboratory test results, printouts, and videotapes) for source data verification, provided that 
patient confidentiality is maintained in accordance with local requirements.
The investigator must maintain the original records (ie, source documents) of each patient’s data 
at all times. Examples of source documents are hospital records, office visit records, examining 
physician’s finding or notes, consultant’s written opinion or notes, laboratory reports, drug 
inventory, study drug label records, diary data, protocol-required worksheets, and CRFs that are 
used as the source (see Section 3.13).
The investigator will maintain a confidential patient identification list that allows the 
unambiguous identification of each patient. All study-related documents must be kept until 
notification by the sponsor.

QUALITY CONTROL AND QUALITY ASSURANCE
11.1.
Protocol Amendments and Protocol Deviations and Violations
11.1.1.
Protocol Amendments
No changes from the final approved (signed) protocol will be initiated without the prior written 
approval or favorable opinion of a written amendment by the IEC/IRB and national and local 
competent authorities, as applicable, except when necessary to address immediate safety 
concerns to the patients, or when the change involves only nonsubstantial logistics or 
administration. The principal investigator at each investigational center, the coordinating 
investigator (if applicable), and the sponsor will sign the protocol amendment.
11.1.2.
Protocol Violations
Any deviation from the protocol that affects, to a significant degree, (a) the safety, physical, or 
mental integrity of the subjects of the study and/or (b) the scientific value of the study will be 
considered a protocol violation. Protocol violations may include nonadherence on the part of the 
patient, the investigator, or the sponsor to protocol-specific inclusion and exclusion criteria, 
primary objective variable criteria, or GCP guidelines; noncompliance to study drug 
administration; and use of prohibited medications. Protocol violations will be identified and 
recorded by investigational center personnel in the CRF. All protocol violations will be reported 
to the responsible IEC/IRB, as required.
When a protocol violation is reported, the sponsor will determine whether to discontinue the 
patient from the study or permit the patient to continue in the study, with documented approval 
from the medical expert. The decision will be based on ensuring the safety of the patient and 
preserving the integrity of the study.
Changes in the inclusion and exclusion criteria of the protocol are not prospectively granted by 
the sponsor. If investigational center personnel learn that a patient who did not meet protocol 
inclusion and exclusion criteria was entered in a study, they must immediately inform the 
sponsor of the protocol violation. If such patient has already completed the study or has 
withdrawn early, no action will be taken but the violation will be recorded.
11.2.
Information to Study Personnel
The investigator is responsible for giving information about the study to all staff members 
involved in the study or in any element of patient management, both before starting the study and 
during the course of the study (eg, when new staff members become involved). The investigator 
must assure that all study staff members are qualified by education, experience, and training to 
perform their specific responsibilities. These study staff members must be listed on the 
investigational center authorization form, which includes a clear description of each staff 
member’s responsibilities. This list must be updated throughout the study, as necessary.
The study monitor is responsible for explaining the protocol to all study staff, including the 
investigator, and for ensuring that they comply with the protocol. Additional information will be 

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
103
made available during the study when new staff members become involved in the study and as 
otherwise agreed upon with either the investigator or the study monitor.
11.3.
Study Monitoring
To ensure compliance with GCP guidelines, the study monitor or representative is responsible 
for ensuring that patients have signed the informed consent form and the study is conducted 
according to applicable standard operating procedures (SOPs), the protocol, and other written 
instructions and regulatory guidelines.
The study monitor is the primary association between the sponsor and the investigator. The main 
responsibilities of the study monitor(s) are to visit the investigator before, during, and after the 
study to ensure adherence to the protocol, that all data are correctly and completely recorded and 
reported, and that informed consent is obtained and recorded for all patients before they 
participate in the study and when changes to the consent form are warranted, in accordance with 
IEC/IRB approvals.
The study monitor(s) will contact the investigator and visit the investigational center at regular 
intervals throughout the study. The study monitor will be permitted to check and verify the 
various records (CRFs and other pertinent source data records, including specific electronic 
source documentation [see Section 3.13]) relating to the study to verify adherence to the protocol 
and to ensure the completeness, consistency, and accuracy of the data being recorded. If 
electronic CRFs are used for the study, the study monitor will indicate verification by 
electronically applying source document verification flags to the CRF and will ensure that all 
required electronic signatures are being implemented accordingly.
As part of the supervision of study progress, other sponsor personnel may, on request, 
accompany the study monitor on visits to the investigational center. The investigator and 
assisting staff must agree to cooperate with the study monitor to resolve any problems, errors, or 
possible misunderstandings concerning the findings detected in the course of these monitoring 
visits and/or provided in follow-up written communication.
11.4.
Clinical Product Complaints
A clinical product complaint is defined as a problem or potential problem with the physical 
quality or characteristics of clinical drug supplies and/or clinical device supplies used in a 
clinical research study sponsored by Teva. Examples of a product complaint include, but are not 
limited to, the following:

suspected contamination

questionable stability (eg, color change, flaking, crumbling, etc)

defective components

missing or extra units (eg, primary container is received at the site with more or less 
than the designated number of units inside)

incorrect packaging or incorrect or missing labeling/labels

unexpected or unanticipated taste or odor (or both)

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
104

device not working correctly or appears defective in some manner
Each investigational center will be responsible for reporting a possible clinical product complaint 
by completing the Product Complaint Form provided by Teva and emailing it to 
within 48 hours of becoming aware of the issue.
For complaints involving a device or other retrievable item, it is required that the device (or 
item) be sent back to the sponsor for investigative testing whenever possible. For complaints 
involving a drug product, all relevant samples (eg, the remainder of the patient’s drug supply) 
should be sent back to the sponsor for investigative testing whenever possible.
11.4.1.
Product Complaint Information Needed from the Investigational Center
In the event that the Product Complaint Form cannot be completed, the investigator will obtain 
the following information, as available:

investigational center number and principal investigator name

name, phone number, and address of the source of the complaint 

clinical protocol number

patient identifier (patient study number) and corresponding visit numbers, if 
applicable

patient number, bottle, and kit numbers (if applicable)

product available for return (yes, no)

product was taken or used according to protocol (yes, no)

description or nature of complaint

associated serious adverse event (yes, no)

clinical supplies unblinded (yes, no)

date and name of person receiving the complaint
Note: Reporting a complaint must not be delayed because not all the required information can be 
immediately obtained. Known information must be immediately reported. The sponsor will 
collaborate with the investigator to obtain any outstanding information.
11.4.2.
Handling the Study Drug at the Investigational Center
The investigator is responsible for retaining the product in question in a location separate from 
the investigator’s clinical study supplies. The sponsor may request that the investigator return the 
product for further evaluation and/or analysis. If this is necessary, the clinical study monitor or 
designee will provide the information needed for returning the study drug.
If it is determined that the investigational center must return all of the study drug, the sponsor 
will provide the information needed to handle the return.
The integrity of the randomization code and corresponding blinded clinical supplies will be 
maintained whenever possible. A serious adverse event or the potential for a product quality 

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
105
problem existing beyond the scope of the complaint may be a reason to unblind the clinical 
supplies for an affected patient.
11.4.3.
Adverse Events or Serious Adverse Events Associated with a Product Complaint
If there is an adverse event or serious adverse event, the protocol should be followed.
11.4.4.
Documenting a Product Complaint
The investigator will record a description of the product complaint in the source documentation 
as well as any actions taken to resolve the complaint and to preserve the safety of the patient. 
Once the complaint has been investigated by the sponsor and the investigator, if necessary, an 
event closure letter may be sent to the investigational center where the complaint originated or to 
all investigational centers using the product.
11.5.
Audit and Inspection
The sponsor may audit the investigational center to evaluate study conduct and compliance with 
protocols, SOPs, GCPs, and applicable regulatory requirements. The sponsor’s Global Clinical 
Quality Assurance department, independent of the Global Clinical Development department, is 
responsible for determining the need for (and timing of) an investigational center audit.
The investigator must accept that regulatory authorities, and sponsor representatives may 
conduct inspections to verify compliance with GCP guidelines.

ETHICS
Details of compliance with regulatory guidances and applicable laws are provided in Section 1.6.
12.1.
Informed Consent
The investigator, or a qualified person designated by the investigator, should fully inform the 
patient of all pertinent aspects of the study, including the written information approved by the 
IEC/IRB. All written and/or oral information about the study will be provided in a language as 
nontechnical as practical and understood by the patient. The patient should be given ample time 
and opportunity to inquire about details of the study and to decide whether or not to participate in 
the study. The above should be detailed in the source documentation.
Written informed consent will be obtained from each patient before any study-specific 
procedures or assessments are done and after the aims, methods, anticipated benefits, and 
potential hazards are explained, according to the IEC/IRB requirements. The patient’s 
willingness to participate in the study will be documented in a consent form, which will be 
signed and personally dated by the patient and by the person who conducted the informed 
consent discussion. The investigator will keep the original consent forms, and copies will be 
given to the patients. It will also be explained to the patients that the patient is free to refuse entry 
into the study and free to withdraw from the study at any time without prejudice to future 
treatment.
Patients will be asked to sign a separate informed consent form if they agree to provide blood 
samples for pharmacogenomic assessment.
12.2.
Health Authorities and Independent Ethics Committees/Institutional 
Review Boards
Before this study starts, the protocol will be submitted to the national/local health authorities and 
to each IEC/IRB for review. As required, the study will not start at a given investigational center 
before the IEC/IRB and health authority (where applicable) for the center to give written 
approval or a favorable opinion.
12.3.
Confidentiality Regarding Study Patients
The investigator must ensure that the privacy of the patients, including their identity and all 
personal medical information, will be maintained at all times. In CRFs and other documents or 
image material submitted to the sponsor, patients will be identified not by their names, but by an 
identification code (ie, identification number).
Personal medical information may be reviewed for the purpose of patient safety and/or verifying 
data in the source and transcribed onto the CRF. This review may be conducted by the study 
monitor, properly authorized persons on behalf of the sponsor, the quality assurance unit, and/or 
regulatory authorities. Personal medical information will always be treated as confidential.

DATA HANDLING, DATA QUALITY CONTROL, AND RECORD 
KEEPING
13.1.
Data Collection
Data will be collected using CRFs that are specifically designed for this study. The data collected 
on the CRFs will be captured in a clinical data management system (CDMS) that meets the 
technical requirements described in 21CFR Part 11. The CDMS will be fully validated to ensure 
that it meets the scientific, regulatory, and logistical requirements of the study before it is used to 
capture data from this study. Before using the CDMS, all users will receive training on the 
system and study-specific training. After they are trained, users will be provided with individual 
system access rights.
Data will be collected at the investigational center by appropriately designated and trained 
personnel, and CRFs must be completed for each patient who provided informed consent. Patient 
identity should not be discernible from the data provided on the CRF. Data will be verified using 
the data source by the study monitor, and reviewed for consistency by Data Management using 
both automated logical checks and manual review. All data collected will be approved by the 
investigator at the investigational center. This approval acknowledges the investigator’s review 
and acceptance of the data as being complete and accurate.
If data are processed from other sources (eg, central laboratory, bioanalytical laboratory, central 
image center, electronic diary data, or ePRO Tablet), the results will be sent to the investigational 
center, where they will be retained but not entered into the CRF, unless otherwise specified in the 
protocol. These data may also be sent electronically to the sponsor (or organization performing 
data management) for direct entry into the clinical database. Laboratory test results will not be 
entered into the CRF, unless otherwise noted in the protocol. All data from other sources will be 
available to the investigators.
For patients who enter a study but do not meet entry criteria, at a minimum, data for screen 
failure reason, demography, and adverse events from the time of informed consent will be 
entered into the CRF. 
13.2.
Data Quality Control 
Data Management is responsible for the accuracy, quality, completeness, and internal 
consistency of the data from this study. Data handling, including data quality control (QC), will 
comply with international regulatory guidelines, including ICH GCP guidelines. Data 
management and control processes specific to this study, along with all steps and actions taken 
regarding data management and data QC, will be described in a data management plan.
Case report forms received will be processed and reviewed for completeness, consistency, and 
the presence of mandatory values. Applicable terms will be coded according to the coding 
conventions for this study. Logical checks will be implemented to ensure data quality and 
accuracy. Any necessary changes will be made in the clinical database, and data review and 
validation procedures will be repeated as needed. Data from external sources will be compared 
with the information available in the CDMS. Discrepancies found will be queried.

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
109
Data corrections in the CDMS will be made using the CDMS update function. The system 
requires a reason for each change and keeps a complete audit trail of the data values, dates and 
times of modifications, and authorized electronic approvals of the changes.
At the conclusion of the study, the CDMS and all other study data will be locked to further 
additions or corrections. Locking the study data represents the acknowledgement that all data 
have been captured and confirmed as accurate.
13.3.
Archiving of Case Report Forms and Source Documents
13.3.1.
Sponsor Responsibilities
The sponsor will have final responsibility for the processing and QC of the data. Data 
management oversight will be carried out as described in the sponsor’s SOPs for clinical studies.
Day-to-day data management tasks for this study are delegated to a CRO, and these functions 
may be carried out as described in the SOPs for clinical studies at that organization. These SOPs 
will be reviewed by the sponsor before the start of data management activities. The original 
CRFs will be archived by the sponsor. Center-specific CRFs will be provided to the respective 
investigational centers for archiving.
13.3.2.
Investigator Responsibilities
The investigator must maintain all written and electronic records, accounts, notes, reports, and 
data related to the study and any additional records required to be maintained under country, 
state/province, or other local laws, including, but not limited to, the following:

full case histories

signed informed consent forms

patient identification lists

CRFs for each patient on a per-visit basis

data results from other sources (eg, central laboratory, bioanalytical laboratory, 
central image center, and electronic diary data)

safety reports

Placebo-Controlled Study–Episodic Migraine
Clinical Study Protocol with Amendment 01
Study TV48125-CNS-30050
110
The investigator will retain all records related to the study until the CRO or sponsor sends 
written notification that records may be destroyed. If, after 10 years from study completion, or 
earlier (in the case of the investigative center closing or going out of business), the investigator 
reasonably determines that study record retention has become unduly burdensome, and sponsor 
has not provided written notification of destruction, then the investigator may submit a written 
request to sponsor at least sixty 60 days before any planned disposition of study records. Upon 
receipt of such request, the sponsor may make arrangements for appropriate archival or 
disposition, including requiring that the investigator deliver such records to the sponsor. The 
investigator shall notify the sponsor of any accidental loss or destruction of study records.

SUMMARY OF CHANGES TO PROTOCOL TV48125-CNS-30049
17.1.
Amendment 01 Dated 30 March 2016
The primary reasons for this amendment are as follows:

To incorporate required revisions based on health authority input from the European 
Medicines Agency, FDA, and Pharmaceuticals and Medical Devices Agency.

To provide clarifying language for the inclusion and exclusion criteria.

To clarify allowed and disallowed preventive medications

To revise protocol-defined adverse events of special interest, and to add clinical 
criteria for diagnosing anaphylaxis

To update and/or clarify versions of certain exploratory endpoints, including the 
EQ-5D (now -5L) and PGIC, respectively.
This revision is considered to be substantial by the sponsor’s Authorized Representative. Other 
nonsubstantial revisions have been made to the protocol (and protocol synopsis, as appropriate). 
These changes are unlikely to affect to a significant degree the safety or rights (physical or 
mental integrity) of the patients in the clinical study or the scientific value of the clinical study.
Where indicated, Table 1 (Study Procedures and Assessments) has been revised to reflect 
changes described below.

BACKGROUND INFORMATION
1.1 Introduction (Other sections affected by this change: Section 16)
However, approximately 3% to 6% of individuals 
with EM evolve, in any given year, to a significantly 
more disabling condition called chronic migraine 
(CM) (Bigal et al 2008, Lipton et al 2007, Scher et 
al 2003). Individuals with CM present with 
headaches of any severity on 15 or more days per 
month and have full-blown migraine on at least 8 
days per month (Classification Committee of the 
IHS, 2013). A sizable proportion of individuals with 
CM experiences daily headaches and, therefore, faces
considerable disability (Bigal and Lipton 2008).
[…]
Calcitonin gene-related peptide (CGRP) is a well-
studied neuropeptide found at the centers of the 
migraine processes, both centrally and peripherally 
(Eftekhari and Edvinsson 2010, Olesen 2011).

these classes of drugs that are used with varying 
response rates to prevent migraine, only 5 marketed 
drugs are approved by the Food and Drug 
Administration (FDA) in the United States (US) 
for the preventive treatment of migraine; 4 of 
them are approved for the prophylaxis of 
migraine: propranolol, timolol maleate, 
divalproex sodium, and topiramate. The clinical 
trials (Brandes et al 2004, Klapper 1997, Mathew 
et al 1995, Nadelmann et al 1986, Silberstein et al 
2004) that supported registration of these drugs 
for this indication were conducted before the 
establishment of CM as a single entity and 
generally included patients with headaches on less 
than 15 days per month. 4 (propranolol [Inderal®, 
Akrimax Pharmaceuticals], timolol [Blocadren®, 
Merck & Co, Inc.], divalproex sodium [Depakote®, 
AbbVie, Inc.], and topiramate [Topamax®, Jannsen]) 
are approved by the United States Food and Drug 
Administration (FDA) for the prevention or 
prophylaxis of EM and only 1 (onabotulinumtoxinA 
[Botox®, Allergan, Inc.]) is approved for the 
prevention of CM Only 1 medication, 
onabotulinumtoxinA, is approved for prophylaxis 
of CM (Lipton and Silberstein 2015). Notably, 
despite evidence suggesting that inhibition of CGRP 
is effective as a preventive migraine treatment, no 
available treatment directly targets CGRP.

[…]
The inflammation was consideredsuspected to be the 
result of immune complex formation/deposition from 
the monkeys’ immunogenic response to the drug 
(TEV-48125) and was not considered to be clinically 
relevant. In the pivotal 6-month chronic toxicity 
study in monkeys following once-weekly sc dosing at 
dosage levels of up to 300 mg/kg/week, achieving 
high exposure throughout the study, no 
microscopic findings 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 typical of a humanized IgG2 
molecule, with low mean plasma clearance, low 
volume of distribution at steady state, and a long 
t½. Exposure as defined by the maximum observed 
plasma drug 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, pivotal reproductive and developmental 
toxicity studies in animalsrabbits and rats with 
TEV-48125 were conducted. The in life portion was

Blinding/Unblinding
Pharmacokinetic data may be assessed during the 
study. For patients who have pharmacokinetic sample 
bioanalysis and/or data analysis conducted, the 
individuals responsible for sample bioanalysis and 
other responsible personnel will know who received 
each TEV 48125 dose regimen and who received 
placebo during the study (of those patients only).
Personnel responsible for bioanalysis will be 
provided with the randomization code in order to 
facilitate the analysis. However, the personnel 
responsible for bioanalysis and pharmacokinetic data 
analysis will not have access to clinical safety and 
efficacy data and will provide concentration data to 
other personnel in a manner that will not identify 
individual patients (ie, a dummy patient identifier 
will be linked to an individual patient’s concentration 
data).

study and/or (b) the scientific value of the study 
will be considered a protocol violation. Protocol 
violations include enrolling patients in violation of key 
eligibility criteria designed to ensure a specific subject 
population, failing to collect data necessary to 
interpret primary endpoints, Protocol violations may 
include nonadherence on the part of the patient, 
the investigator, or the sponsor to protocol-specific 
inclusion and exclusion criteria, primary objective 
variable criteria, or GCP guidelines; noncompliance 
to study drug administration,; use of prohibited 
medications, GCP noncompliance, or any other 
deviations that may have an impact on the processes 
put in place for the care and safety of the patients or 
compromise the scientific value of the trial. 
Protocol violations will be identified and recorded by 
investigational center personnel onin the CRF. All 
protocol violations will be reported to the responsible 
IEC/IRB, as required.
When a protocol violation is reported, the sponsor will 
determine whether to discontinue the patient from the 
study or permit the patient to continue in the study, 
with documented approval from the medical 
representativeexpert. The decision will be based on 
ensuring the safety of the patient and preserving the 
integrity of the study. 
Deviations from Changes in the inclusion/ and

APPENDIX E. GUIDANCE ON SAFETY MONITORING
Guidance on Monitoring Patients with Elevated Liver Function Tests
Liver enzymes (ALT, AST, GGT, and ALP) as well as total and direct bilirubin will be measured 
(and indirect bilirubin will be calculated) at each study 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 study), a 
thorough medical history and physical examination with a focus on liver disease should be 
undertaken.1 In addition, the patient should be instructed to refrain from alcoholic beverages.
In case of symptoms compatible with drug-induced liver injury during the study, patients will be 
instructed to return to the study center for an unscheduled visit or to go to the emergency room 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 according to the discretion of the 
treating physician.
Elevation of Either ALT or AST to ≥3× ULN
Confirmation is required prior to study drug 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 study drug discontinuation, but the assessments below should be performed). 
The following procedures should be followed:

The day in which the abnormal value is received from the laboratory will be 
considered as day 0.

The investigator should repeat the test for confirmation purposes (this may be 
performed in a local laboratory along with complete blood count [CBC] and 
differential to assess for eosinophilia. In general, in case a blood sample is sent to a 
local laboratory, the following assessments [and reference ranges] are mandatory: 
ALT [serum glutamic pyruvic transaminase], AST [serum glutamic oxaloacetic 
transaminase], ALP, total and direct bilirubin, CBC [with differential for eosinophil 
count, separate tube], and INR [separate tube; not to be sent in a confirmatory test]). 
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
                                                
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 investigator. Physical examination, including signs of chronic liver disease.

163
Additional Tests/Evaluations:
Upon confirmation of the abnormality as noted above, the following additional evaluations 
should be performed and results should be recorded in the CRF:

serology for hepatitis A (antibody and immunoglobulin M [IgM] and IgG), B (core 
antibody total, core IgM, and surface antigen), and C viruses (central laboratory)

serology for autoimmune hepatitis: anti-nuclear antibodies (titer), anti-smooth muscle 
antibodies, and anti-liver kidney microsomal antibodies (central laboratory); further 
testing may be required in case of a positive result for hepatitis B or C

ultrasound examination of the liver and biliary tract at the investigator’s discretion

other diagnostic tests/consultations as deemed necessary by the investigator 
(eg, serology for hepatitis E virus in case of travel to endemic geography)

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:

Alanine aminotransferase, AST, GGT, ALP, total and direct bilirubin, CBC and 
differential (to assess for eosinophilia), and INR should be monitored on days 5 
(±2 days), 8 (±2 days), 14 (±3 days), and 28 (±3 days). On at least 1 of these days, the 
test should be performed centrally. (The INR should be sent to a local laboratory 
only.)

In cases where a local laboratory is used, the results should be recorded in the CRF, 
accompanied by the reference range of the relevant measurements.

Should the abnormality (≥3× the ULN in case baseline was within the normal range 
or ≥2× the ULN in case the baseline value was above ULN but still <5× the ULN) 
persist further, the patient will be followed according to the investigator’s discretion, 
but a blood sample for ALT, AST, GGT, ALP, and total and direct bilirubin should 
be sent to the central laboratory at least once a month.
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:

Alanine aminotransferase, AST, GGT, ALP, total and direct bilirubin, CBC and 
differential count (to assess for eosinophilia), and INR should be monitored twice a 
week.

At least for every other measurement, the tests should be sent to the central 
laboratory. The rest of the tests may be sent to a local laboratory. The INR should 
always be sent to a local laboratory.

ALT or AST ≥8× the ULN
In addition to the above procedures required for any elevation to levels >3× the ULN:

The study drug should be discontinued immediately, and the early withdrawal visit 
should be performed.

For follow-up guidance, please see below section “Follow-Up of Liver Enzymes 
After Stopping Rules Are Met.”
Stopping Rules
In the following circumstances, the study drug 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 study drug should be 
invited to the site to return the study drug. Early withdrawal visit activities should be 
performed as soon as possible.

Liver enzymes should be monitored until normalization or stabilization of the 
abnormality, according to the discretion of the investigator.

In any case, following the early withdrawal visit, the minimal follow-up period will 
be 30 days and will include measurement of liver enzymes at least once weekly (may 
be performed in local laboratory, with at least 1 test being sent to the central 
laboratory).

Every effort should be made to complete the additional tests/evaluations, as described 
above.
