General Design:  
This is a 16-week, multicenter, randomized, double-blind, double-dummy, placebo-controlled, 
parallel-group study to compare the efficacy and safety of 2 dose regimens of fremanezumab 
versus placebo in adult patients for the prevention of CCH. The study will consist of a screening 
visit, a run-in period lasting approximately 4 weeks (+3 days), and a 12-week double-blind 
treatment period. During the course of any CH attack, patients will be allowed to use acute 
medications to treat acute headaches, as needed (PRN). 
Patients will complete a screening visit (visit 1) after providing written informed consent, and 
eligible patients will enter a run-in period lasting at least 4 weeks (+3 days) during which they 
will enter baseline CH attack information into an electronic diary device daily. Patients will 
return to the study center after completing the run-in period (visit 2 [week 0]). Patients who had 
at least 10 CH attacks during the run-in period and who continue to meet eligibility criteria 
(including entry of CH attack information in an electronic diary, demonstrating compliance for 
85% of days during the run-in period) will be randomly assigned at visit 2 (week 0) in a 
1:1:1 ratio to 1 of 3 treatment groups as follows: 
• fremanezumab 900-mg iv loading dose group: fremanezumab at 900 mg administered 
via an approximately 1-hour iv infusion at visit 2 (week 0) followed by 
fremanezumab at 225 mg administered as single sc injections (225 mg/1.5 mL) at 
visits 3 and 4 (weeks 4 and 8, respectively) 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
11 
• fremanezumab 675-mg sc loading dose group: fremanezumab at 675 mg administered 
as 3 sc injections (225 mg/1.5 mL) at visit 2 (week 0) followed by fremanezumab at 
225 mg administered as single sc injections (225 mg/1.5 mL) at visits 3 and 
4 (weeks 4 and 8, respectively) 
• placebo group: placebo administered via an approximately 1-hour iv infusion and as 
3 sc injections at visit 2 (week 0) followed by placebo administered as single sc 
injections at visits 3 and 4 (weeks 4 and 8, respectively) 
In order to maintain blinding throughout the study, the number of infusions and injections at each 
visit will be the same for all patients regardless of the treatment group to which they are 
randomized. Thus, all patients will receive an iv infusion of test IMP or placebo IMP followed 
by 3 sc injections of test IMP or placebo IMP at visit 2 (week 0), and all patients will receive 
single sc injections of test IMP or placebo IMP at visits 3 and 4 (weeks 4 and 8, respectively). 
Patients will also return for an end of treatment (EOT) visit, approximately 4 weeks after the 
administration of the last dose of IMP, in order to evaluate ADAs, fremanezumab concentrations, 
biomarkers, and safety assessments. 
CH attack information will be captured daily during the double-blind treatment period using an 
electronic diary device. Assessments of change in quality of life and health status (using the 
Hospital Anxiety and Depression Scale, EuroQol-5 Dimension questionnaire, 12-Item Short-
Form Health Survey, Impact on Partner and Family questionnaire, and Work Productivity and 
Activity Impairment questionnaire); satisfaction with treatment (using the PPSI and Patient 
Global Impression of Change scale); safety evaluations; blood collection for pharmacokinetic, 
immunogenicity, and biomarker analyses; and urine sampling for biomarker analysis will be 
performed at prespecified time points.  
Wearable Sensor Substudy: A subset of patients in selected investigational sites will be offered 
the opportunity to participate in a substudy to understand the utility of physiological biomarker 
measures captured through wearable digital sensor devices as tools to monitor response to 
treatment and disease symptoms (eg, activity/sleep disruption).  
Brief Summary of Study Design for the Trial Registry(s): This is a 16-week study to evaluate 
the efficacy and safety of 2 dose regimens of fremanezumab versus placebo in adult patients for 
the prevention of CCH. Patients who provide written informed consent and complete a screening 
visit (visit 1) will enter a run-in period lasting at least 4 weeks (+3 days) during which they will 
enter baseline CH attack information into an electronic diary device daily. Patients will return to 
the study center after completing the run-in period (visit 2 [week 0]), and patients who continue 
to meet eligibility requirements will be randomized to receive test IMP (fremanezumab 900-mg 
iv or 675-mg sc followed by fremanezumab 225-mg sc monthly) or placebo IMP (placebo iv and 
sc followed by single placebo doses sc monthly). An EOT visit will occur approximately 
4 weeks after the administration of the last dose of IMP to evaluate ADAs, fremanezumab 
concentrations, biomarkers, and safety. 
Efficacy will be evaluated using CH attack data entered daily throughout the treatment period in 
an electronic diary and administration of questionnaires to evaluate change in quality of life, 
health status, and satisfaction with treatment. The safety of fremanezumab in patients with CH 
will be evaluated through adverse event and concomitant medication inquiries, ECGs, vital signs 
measurements, clinical laboratory tests, physical examinations, injection site reaction/pain

assessments, assessments for anaphylaxis and hypersensitivity, and administration of the 
eC-SSRS. In addition, blood will be collected for pharmacokinetic, immunogenicity, biomarker, 
and pharmacogenomic (unless not allowed per local regulation) analyses, and urine will be 
collected for biomarker analysis. 
Method of Randomization and Blinding: Randomization will be performed using electronic 
interactive response technology (IRT). Patients will be randomly assigned with stratification 
based on gender, country, and baseline concomitant preventive medications (yes/no) to the 
fremanezumab 900-mg iv loading dose group, the fremanezumab 675-mg sc loading dose group, 
or the placebo group in a 1:1:1 ratio. The sponsor, investigators, study staff (except for staff 
involved in bioanalytical analyses and interim analyses [by a third-party, unblinded statistician]), 
and patients will be blinded to treatment assignment throughout the study. 
The IRT will manage initial drug supply, maintenance of adequate IMP supplies on site, and 
study randomization centrally. In the event that the IRT system is not functioning for emergency 
unblinding, the next course of action is to contact via phone the IRT on-call customer support 
helpline for manual emergency unblinding.  
The randomization code will be generated by the IRT third-party vendor, following 
specifications from the Biostatistics Department. A Teva statistician will be responsible for 
reviewing the dummy randomization codes, and the final randomization code will be maintained 
by the third-party vendor in a secure location. 
At the time of analysis (after the end of the study), after receiving an unblinding request from the 
Teva statistician, the service provider will provide the unblinded IMP assignments according to 
the processes defined in the relevant Standard Operating Procedure.

IMP=investigational medicinal product; iv=intravenous; n/a=not applicable; sc=subcutaneous. 
The fremanezumab doses, regimens, and routes of administration to be evaluated in this 
double-blind, double-dummy, placebo-controlled study were selected on the basis of 3 key 
factors. First, simulations suggest that maximum observed concentration (Cmax) is the most 
significant pharmacokinetic parameter in the efficacy of fremanezumab (in migraine). As CH is 
considered one of the most severe forms of pain a person can experience, treatments that provide 
quick and lasting relief (ie, for the duration of the cluster period) are a priority for this patient 
population. Second, the biological nature of the disease mandates the need for any treatment to 
desensitize the third order neuron, not the second (as is the case in migraine), suggesting that 
high levels of blockade at the first neuron would be necessary. Third, the favorable safety profile 
of the drug, as well as clinical and nonclinical safety data on exposure, suggest that the proposed 
doses, regimens, and routes of administration will not present any safety concerns. 
In the current study, high doses are planned for the first dose (900 mg iv or 675 mg sc) in order 
to provide a rapid response, especially following iv infusion where higher peak plasma Cmax 
generally occurs at or shortly after the end of infusion compared with 5 to 7 days postdose for sc 
injections. The 2 forms of loading dose will provide data to confirm the benefit of either the iv or 
sc as loading dose. Monthly doses of fremanezumab at 225 mg sc were added to both the initial 
dose of 900 mg iv and 675 mg sc for maintenance of efficacy. Based on modelling, the inclusion 
of a loading dose should allow patients to reach steady state faster. The monthly doses of 225 mg 
sc in this CCH population will account for the continuous attacks, with less than 1 month free of 
headaches between attacks, seen with this CH form. 
A placebo-controlled design is appropriate given the purpose and objectives of this clinical 
study. Inclusion of a placebo-control group is consistent with the IHS guidelines for controlled 
trials of drugs in CH, first edition (Lipton et al 1995). 
Test IMP: Fremanezumab 
Reference IMP: None 
Placebo IMP: Same vehicle and excipients as those for fremanezumab 
Duration of Patient Participation and Maximal Exposure to IMP: Patient participation will 
last for approximately 16 weeks (including a run-in period lasting approximately 4 weeks 
[+3 days] and a 12-week double-blind treatment period). 
Study Duration: 24 months from Q4/2016 to Q3/2018

End of Study: End of study is defined as the date the last patient attends the EOT/early 
withdrawal visit. 
Plans for Treatment or Care after the Patient Has Ended Participation in the Study: Upon 
completion of the final study assessments, early withdrawal from the study, or discontinuation 
for any reason, patients will be offered the opportunity to enter a 32-week long-term safety study 
(as described in Study TV48125-CNS-30058) for safety and ADA evaluation without additional 
dosing. Patients who satisfactorily complete the study may be offered to enroll the long-term 
safety Study TV48125-CNC-30058 for 68 weeks (as described in this study protocol) to receive 
additional dosing and a final follow-up visit for safety and ADA evaluation. In either case, 
during the period of the long-term safety study, where patients are not receiving additional 
dosing (and are waiting for ADA evaluation), these patients should be treated with standard of 
care as appropriate. A separate protocol was issued for the long-term safety study. 
Inclusion Criteria: Patients may be included in the study only if they meet all of the following 
criteria:

w. The patient has a history of alcohol and/or drug abuse that in the investigator’s 
opinion could interfere with the study evaluations or the patient’s safety. 
Statistical Considerations:  
Sample Size Rationale: A sample size of 258 patients (86 evaluable patients completing the 
study per treatment group) will provide at least 90% power to detect a treatment difference of 
4 CH attacks in the monthly average (assuming a common standard deviation [SD] of 8 CH 
attacks) at a 2-sided alpha level of 0.05. Assuming a 14% discontinuation rate, approximately 
300 patients will be randomized in the trial. 
Analysis of Primary Endpoint: The primary efficacy endpoint for this study will be derived 
from CH attack data (ie, occurrence and number of CH attacks, duration of CH attack(s), severity 
of CH attack(s), and acute CH-specific medication and oxygen use) collected daily using an 
electronic headache diary device.  
For the purpose of this study, a CH attack will be endorsed when the following situations occur:  
1. Severe or very severe unilateral orbital, supraorbital, and/or temporal pain lasting 15 to 
180 minutes 
2. Either or both of the following: 
• at least 1 of the following symptoms or signs, ipsilateral to the headache: 
− conjunctival injection and/or lacrimation 
− nasal congestion and/or rhinorrhea 
− eyelid edema 
− forehead and facial sweating 
− forehead and facial flushing 
− sensation of fullness in the ear 
− miosis and/or ptosis 
• a sense of restlessness or agitation 
Analysis of Secondary Endpoints: Secondary efficacy endpoints will be derived from CH 
attack data (ie, occurrence and number of CH attacks, duration of CH attack(s), severity of CH 
attack(s), and acute CH-specific medication and oxygen use) collected daily using an electronic 
headache diary device. In addition, oxygen and acute treatment use will be derived from the 
concomitant medications inquiries and patient perception of improvement will be evaluated at 
time points specified in Table 2 using the PPSI. 
Primary Efficacy Analysis: The primary efficacy endpoint, the mean change from baseline 
(run-in period) in the monthly average number of CH attacks during the 12-week period after 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
18 
administration of the first dose of the IMP, will be analyzed using an analysis of covariance 
(ANCOVA). The model will include treatment, baseline number of CH attacks, baseline 
preventive medication use (yes or no), gender, and region (US or other). 
Sensitivity Analysis: A sensitivity analysis will be conducted to explore the impact of missing 
data in the primary efficacy analysis. Details will be provided in the statistical analysis plan. 
Secondary and Exploratory Efficacy Analysis: The continuous secondary efficacy endpoints 
will be analyzed using an ANCOVA method or a mixed model for repeated measures. For the 
proportion of responders, defined as 50% or more reduction from baseline in the monthly 
average number of CH attacks, data will be analyzed using a Cochran-Mantel-Haenszel test 
stratified by baseline preventive medication use (yes/no). 
Multiple Comparisons and Multiplicity: Hochberg’s step-up method will be implemented to 
test primary and secondary endpoints while controlling the overall type 1 error rate at 0.05. 
Safety 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 test IMP 
(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.  
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 the test IMP. 
Changes in laboratory, ECG, and vital signs measurements 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. 
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. 
Tolerability Analysis: Tolerability was not specifically defined 
Pharmacokinetics Analysis: Pharmacokinetics plasma concentration results (fremanezumab) 
will be tabulated descriptively at each planned sampling time point by treatment group. 
In addition, the most appropriate population pharmacokinetics model will be developed, and 
covariates that may affect it will be tested for inclusion in the model. This analysis will be 
reported separately. 
Pharmacodynamics Analysis: Not applicable 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
19 
Pharmacokinetics/Pharmacodynamics Analysis: The pharmacokinetics/pharmacodynamics 
relationship may be estimated by compartmental techniques. The pharmacokinetics parameters 
will be based on fremanezumab measurements. The pharmacodynamics parameters will be the 
efficacy response(s).  
The pharmacokinetics/pharmacodynamics relationship may be estimated using the most 
appropriate model after comparing different candidate models for their quality of fit. Covariates 
that may affect the pharmacokinetics/pharmacodynamics relationship will be tested for inclusion 
in the model. If performed, this analysis will be reported separately.  
Immunogenicity Analysis: A summary of immunogenicity results will be provided, and the 
incidence of immunogenicity will be calculated. The impact of immunogenicity on the 
pharmacokinetics profile, IMP efficacy, and clinical safety will be evaluated. This ADA-impact 
analysis will be reported separately. 
Exploratory Biomarker Analysis: Biomarker analysis will include logistic regression, receiver 
operating characteristic curves, and summary statistics. Analysis will be reported separately. 
Measurements will be made using validated assays. 
Pharmacogenomic Analysis: Pharmacogenomic analysis results will be summarized for each 
gene tested. An attempt will be made to correlate clinical observations (pharmacokinetics, safety, 
efficacy, or other effects) with the genotypes observed. Additional pharmacogenomic analysis 
may be conducted at a later time and will be reported in a separate addendum report.  
Ancillary Studies Analysis: Analysis will include summary statistics and multimodal 
algorithms to monitor physiological activity, sleep/wake activity, and treatment responses. 
Results will be reported separately. 
Planned Interim Analysis: An interim analysis for futility will be performed once 50% of 
patients (the first 150 patients) have completed 12-week assessments during the double-blind 
study period or have withdrawn from the study early. An independent statistician from a third 
party will perform the analysis.

INTRODUCTION AND BACKGROUND INFORMATION 
1.1. 
Cluster Headache 
Cluster headache (CH) is a primary headache disorder characterized by repetitive attacks of 
excruciating unilateral head pain and associated with cranial autonomic features (such as 
lacrimation, conjunctival injection, nasal congestion, nasal rhinorrhea, and partial Horner’s 
syndrome) (Rozen 2005). CH attacks last up to 180 minutes and occur from once every other day 
to 8 times a day. Cluster periods usually last a few months (typically 3 months) followed by 
remission periods of months to years (Headache Classification Committee of the International 
Headache Society [IHS] 2013). A unique feature of CH is the circadian and circannual 
periodicity nature of the headache attacks. Peak time periods for daily CH onset are 0100 to 
0200, 1300 to 1500, and after 2100, with night awakening attacks being more severe than those 
occurring during the day (Rozen 2005). Some patients tend to have seasonal attacks related to the 
duration of the photoperiod, with the highest incidence of attacks occurring in January or July 
with possible relation to solstices or equinoxes (Kudrow 1987).  
There are 2 forms of CH: episodic cluster headache (ECH), which is the most common form, 
where distinct pain-free periods lasting at least 1 month are evident, and chronic cluster headache 
(CCH) occurring for more than 1 year without remission or with remission periods lasting less 
than 1 month. About 10% to 15% of patients with CH have the CCH form (Headache 
Classification Committee of the IHS 2013).  
The pathophysiology of CH is complex and not fully understood. Current theories implicate 
mechanisms such as vascular dilation, trigeminal nerve stimulation, and circadian effects. 
Histamine release, an increase in mast cells, genetic factors, and autonomic nervous system 
activation may also contribute (Weaver-Agostoni 2013). However, 3 major features of CH are 
the main focus for understanding its pathophysiological model: trigeminal distribution of the 
pain (including association with neuropeptide level changes), ipsilateral cranial autonomic 
features, and (circadian) episodic pattern of attacks (May 2005). 
The excruciatingly severe unilateral pain is likely to be mediated by activation of the first 
(ophthalmic) division of the trigeminal nerve, whereas the autonomic symptoms such as 
lacrimation are due to activation of the cranial parasympathetic outflow from the seventh cranial 
nerve (Goadsby 2002). When the trigeminal system becomes highly activated, the excitation 
spreads to the superior salivary nucleus, resulting in excitation from the sphenopalatine ganglion 
to parasympathetic nerves of intracranial large blood vessels, lacrimal glands, and nasal mucosa. 
As a result, ipsilateral autonomic symptoms such as Horner’s sign, lacrimation, nasal congestion, 
and rhinorrhea are manifested (Goadsby 2002, Japanese Headache Society 2013). Stimulation of 
the superior sagittal sinus activates the trigeminovascular pathway, and this also results in the 
release of neuropeptides such as calcitonin gene-related peptide (CGRP) and vasoactive 
intestinal peptide (VIP) in the external jugular vein. During attacks, the levels of CGRP and VIP 
are raised in cranial venous blood in all patients.

1.1.1. 
Rationale for Fremanezumab Development as a Preventive Treatment for 
Cluster Headache 
Worldwide, there are currently no approved medications for the preventive treatment of CH, and 
medications used off-label in clinical practice for this indication lack meaningful evidence to 
support their use. Among the medications used for ECH and CCH are short-course 
corticosteroids for transitional prophylaxis and verapamil (the most common first-line 
treatment), anti-seizure drugs (valproic acid, topiramate), ergotamine, melatonin, and capsaicin 
for maintenance prophylaxis. Lithium and deep-brain stimulation have also been used as 
preventive treatments for CCH (Weaver-Agostoni 2013). Each of these treatment options is 
suboptimal due to limited evidence of efficacy, troublesome side effects, and/or an unfavorable 
risk to benefit ratio (Rozen 2005, Weaver-Agostoni 2013). 
Teva is developing fremanezumab (TEV-48125) for the preventive treatment of CH (chronic and 
episodic forms). Fremanezumab is a potent, selective CGRP binder and blocks both CGRP 
isoforms (α- and β-CGRP) from binding to the CGRP receptor. Fremanezumab is highly specific 
for CGRP and does not bind to closely related family members amylin, calcitonin, and 
intermedin. It demonstrates a very weak binding interaction with adrenomedullin (>2 µM 
equilibrium dissociation constant). Two mutations were introduced into the constant region of 
the fremanezumab heavy chain to limit antibody effector functions. This loss of function 
prevents fremanezumab 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). 
Similar to migraine, the trigeminal system plays a pivotal role in the pathophysiology of CH. 
During CH attacks, activation of the trigeminal system causes neurovascular inflammation 
mediated by CGRP and other neuropeptides (Fanciullacci et al 1995, Fanciullacci et al 1997, 
Goadsby and Edvinsson 1994). In CH, the generator appears to be in the posterior grey matter of 
the hypothalamus (third neuron) (May et al 1999). Blocking CGRP in the peripheral ganglia of 
the trigeminal system should result in desensitization of the first and second neurons of the 
trigeminal system. Fremanezumab does not cross the blood brain barrier, but its demonstrated 
safety profile (briefly summarized in Section 1.2) provides an opportunity to block the peripheral 
CGRP released in the trigeminal system, leading to a further desensitization of the third-order 
neuron in the hypothalamus. Thus, fremanezumab could potentially normalize the system and 
prevent further attacks without having central nervous system secondary effects.  
Few, if any, medical disorders are more painful than CH. Treatments that provide quick and 
lasting relief (ie, for the duration of the cluster period) and that prevent CH attacks are therefore 
a priority for this patient population. Results from the Phase 2b studies of fremanezumab in 
patients with migraine demonstrating onset of efficacy as early as 1 week after treatment and 
maintenance of effect throughout the 12-week treatment period (Bigal et al 2015a, Bigal et al 
2015b) suggest that fremanezumab may fulfil these treatment needs for patients with CH.  
1.1.2. 
Study Purpose 
The purpose of the current study is to evaluate the efficacy and safety of fremanezumab, 
administered via the intravenous (iv) and/or subcutaneous (sc) routes, in the prevention of CCH 
in adult patients.

1.2. 
Findings from Nonclinical and Clinical Studies 
Brief summaries of nonclinical pharmacology, pharmacokinetics, and toxicology studies and 
clinical studies are provided in the following sections. More detailed information is provided in 
the Investigator’s Brochure (IB). 
1.2.1. 
Nonclinical Studies 
Fremanezumab was evaluated in nonclinical pharmacology, pharmacokinetics, and toxicology 
studies. Pivotal studies were conducted under Good Laboratory Practice (GLP). 
In in-vitro studies, fremanezumab demonstrated no potential for Fcγ receptor binding, cytokine 
release, or hemolysis, up to tested concentrations of 25.5 mg/mL. The concentrations tested in 
these in vitro assays are relevant to the predicted range of concentrations for administration in 
human subjects. Fremanezumab prevents in vitro cyclic adenosine monophosphate production 
induced by CGRP while not binding to similar peptides such as amylin, calcitonin, or 
adrenomedullin. In vivo pharmacology studies of fremanezumab in animal models indicate that 
fremanezumab 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. 
Safety pharmacology studies to evaluate potential cardiovascular effect were performed. The 
data suggest no treatment-related findings after single and repeated administration up to 
6 months via once weekly administration at high dose levels (up to 300 mg/kg/week). 
Fremanezumab was tested in a series of nonclinical in vivo studies in Sprague Dawley rats and 
cynomolgus monkeys. Fremanezumab was administered to rats and monkeys by the iv or sc 
route for up to 3 months in duration and by sc route in the 6-month chronic toxicity study in 
monkeys, and no toxicological concerns were identified following chronic dosing to 
experimental animals at dose levels up to 300 mg/kg/week.  
It is relevant to note that due to the higher exposure observed in the recent clinical Study 
TV48125-PK-10078 (Japanese bridging study), a re-evaluation of the safety margins was 
performed. An internal investigation indicates that the original assay underestimated 
fremanezumab measured plasma concentrations. Comparison of the exposure parameters of 
maximum observed concentration (Cmax) and area under the plasma concentration-time curve 
from time 0 to infinity (AUC0-∞) from Study LBR-101-011 (including iv dosing), which were 
analyzed by the original bioassay, with the exposure parameters from Study TV48125-PK-
10078, which were analyzed using the newer validated assay for the 225- and 900-mg sc dose 
levels, indicates an apparent exposure difference between 2.9- and 3.5-fold in Study TV48125-
PK-10078 relative to Study LBR-101-011. Thus, the most conservative factor of 3.5 was used to 
recalculate the safety margins, meaning that LBR-101-011 exposure was assumed to be 3.5-fold 
higher than originally reported and, as such, safety margins decreased by 3.5-fold. 
For the 6-month chronic toxicity study in monkeys, the calculated safety margins based on 
exposure (area under the plasma concentration-time curve [AUC]) at 300 mg/kg/week dose, 
which was determined as the no observable adverse effect level (NOAEL), is at least 54-fold 
higher compared to the expected human exposure at a dosing regimen of 900 mg iv loading dose 
followed by the 225-mg sc monthly dose and at least 20-fold higher relative to Cmax.

Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
33 
Nevertheless, it is important to note that the change in safety margins has no impact on the safety 
profile of fremanezumab based on the overall toxicological data. 
In a GLP embryo/fetal developmental toxicity (EFD) study in rabbits, sc injection of 
fremanezumab to pregnant rabbits 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. In addition, a GLP combined fertility and EFD study in rats was conducted, and no 
treatment-related effects on gonadal function, mating behavior, reproductive performance, and 
embryo-fetal survival and development were observed in any dose group. 
The pharmacokinetics of fremanezumab in animals (rats and monkeys) is typical of a humanized 
immunoglobulin G2 (IgG2) molecule, with low mean plasma clearance (CL), low volume of 
distribution at steady state (Vss), and a long terminal elimination half-life (t½). Exposure as 
defined by Cmax and AUC increased linearly across doses following single and repeated once-
weekly dosing. No gender differences in exposure were observed in rats or monkeys. Following 
sc administration, mean systemic exposure values (calculated using AUC from time zero to 
168 hours postdose) were 65% to 67% and 81% to 92% of the equivalent iv doses for rats and 
monkey, respectively, demonstrating reasonably high sc bioavailability. 
To conclude, the overall nonclinical safety data presented in this package support the safe, 
repeated (monthly) administration of fremanezumab in human subjects for the duration of the 
Phase 3 pivotal trials (3 months) and the long-term safety extension (1 year). 
1.2.2. 
Clinical Studies 
The clinical program to date is composed of 6 completed Phase 1 clinical studies in healthy 
subjects (Studies B0141001, B0141002, B0141006, B0141007, LBR-101-008, and 
LBR-101-011) and 2 completed Phase 2b clinical studies in patients with migraine 
(Studies LBR-101-021 and LBR-101-022). In total, 484 subjects/patients (118 healthy subjects 
and 366 patients with migraine) have received at least 1 dose of fremanezumab via iv or sc 
routes of administration in these completed studies. In addition, there are 5 ongoing clinical 
studies of fremanezumab: 2 pivotal efficacy studies in patients with migraine (1 study each for 
patients with chronic migraine and patients with episodic migraine [Studies TV48125-CNS-
30049 and TV48125-CNS-30050]); a long-term safety study in patients with migraine 
(Study TV48125-CNS-30051); a pharmacokinetic, safety, and tolerability Phase 1 study in 
healthy Japanese and Caucasian subjects (Study TV48125-PK-10078); and a Phase 1 study 
(Study TV48125-BE-10114) comparing the pharmacokinetics of fremanezumab administered sc 
using a device referenced to a prefilled syringe configuration. 
Further details may be found in the current IB. 
1.2.2.1. 
Clinical Pharmacology Studies 
A total of 118 healthy subjects received fremanezumab across 6 completed Phase 1 studies in 
doses ranging from 0.2 through 2000 mg. Studies included 2 single-ascending-dose 
pharmacokinetic and pharmacodynamic studies in healthy men (Studies B0141001 and 
B0141002); a 2-cohort, placebo-controlled crossover study to examine the acute effects of 
administration of fremanezumab on capsaicin flare response in healthy men (Study B0141006); a 
parallel-group, repeat-dose study of fremanezumab in healthy subjects (Study B0141007); a 
single-dose study evaluating the safety, tolerability, and pharmacokinetics of doses up to 2000 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
34 
mg administered iv in healthy women (Study LBR-101-008 [formerly referred to as Study 
B0141008]); and a study assessing the safety, tolerability, absolute bioavailability, and 
pharmacokinetics of single iv or sc doses of fremanezumab in healthy subjects (Study LBR-101-
011). 
These Phase 1 studies were analyzed using the original bioanalytical method that has since been 
determined to underestimate measured plasma concentrations. In those analyses, fremanezumab 
pharmacokinetics appeared linear over the dose range from 100 to 2000 mg with Cmax and AUC 
generally increasing in proportion to the dose. 
A recently completed pharmacokinetic, safety, and tolerability study in healthy Japanese and 
Caucasian subjects (Study TV48125-PK-10078) dosed fremanezumab as a single sc dose of 225, 
675, or 900 mg. Plasma concentration-time profile was measured using the current validated 
bioanalytical method and the pharmacokinetic results are described below.  
The pharmacokinetics (non-compartmental analysis) of fremanezumab demonstrated an increase 
in Cmax and AUC values slightly greater than dose proportionality over the sc dose range of 225 
to 900 mg. Median time to maximum observed concentration (tmax) values generally occurred 5 
to 7 days post sc doses. Mean values for apparent total volume of distribution during the terminal 
phase (Vz/F) after a single sc dose ranged from 5.7 to 6.4 L at 225- to 900-mg sc doses. The 
mean apparent total plasma clearance (CL/F) ranged from 0.0777 to 0.0895 mL/min at this dose 
range. The mean t½ ranged from 32.2 to 36.2 days. Fremanezumab exposure parameters and 
overall pharmacokinetic profile were similar for healthy Japanese and Caucasian subjects. 
Comparison of exposure parameters (Cmax and AUC0-∞) from Studies LBR-101-011 and 
TV48125-PK-10078 at the 225-mg and 900-mg sc dose levels indicates a 2.9- to 3.5-fold higher 
exposure in Study TV48125-PK-10078 relative to Study LBR-101-011. The main reason for the 
difference in exposure appears to be the underestimated concentration values from the original 
method. 
1.2.2.2. 
Clinical Safety and Efficacy Studies 
The safety, tolerability, and efficacy of fremanezumab have been evaluated in 
2 completed Phase 2b studies, Studies LBR-101-021 and LBR-101-022, in patients with 
migraine (Bigal et al 2015a, Bigal et al 2015b). The results of both studies showed 
fremanezumab to be superior to placebo for primary and secondary endpoints (benefit at 
3 months of therapy). 
Fremanezumab was well tolerated with favorable safety profile across the 6 completed Phase 1 
and 2 completed Phase 2b studies. In addition, no new safety findings were observed in the 
ongoing Phase 1 study (Study TV48125-PK-10078), and no serious adverse events considered 
related to the investigational medicinal product (IMP) have been reported for the ongoing pivotal 
efficacy studies (Studies TV48125-CNS-30049 and TV48125-CNS-30050, as of 23 April 2016). 
The treatment-emergent adverse events reported in the Phase 1 and Phase 2b 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 fremanezumab, has not been identified; nor has a 
maximally tolerated dose been identified. Overall, the nature and occurrence of the reported 
treatment-related adverse events across the clinical program have not raised any specific safety 
concerns.

1.3. 
Known and Potential Benefits and Risks to Patients 
Information regarding the risks and benefits of fremanezumab in patients is summarized in the 
following sections. Additional information regarding benefits and risks to patients may be found 
in the IB. 
1.3.1. 
Known and Potential Benefits and Risks of the Test Investigational Medicinal 
Product(s) 
Results from Phase 2b clinical studies have demonstrated statistically significant reductions in 
mean headache hours after 1, 2, and 3 months of sc fremanezumab treatment in patients with 
chronic migraine and statistically significant reductions in monthly migraine days after 1, 2, and 
3 months of fremanezumab treatment in patients with episodic migraine. Results for several 
secondary/exploratory endpoints also showed fremanezumab to be superior to placebo.  
Fremanezumab has generally been well tolerated over the ranges of doses evaluated (single 
iv infusions at 0.02 to 2000 mg in healthy subjects, multiple iv infusions at 30 to 300 mg in 
healthy subjects, and multiple sc doses at 225 to 900 mg in healthy subjects and migraine 
patients). The most common treatment-emergent adverse events across all patients/subjects 
studied 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. 
Reports of mild to moderate transient administration site disorders/reactions, including injection 
site bruising, injection site swelling, administration site pain, injection site pain, injection site 
pruritus, injection site dermatitis, injection site rash, injection site edema, injection site 
discomfort, injection site hemorrhage, injection site irritation, injection site mass, and injection 
site hematoma, have occurred with sc administration. In addition, reports of mild and transient 
infusion site pain and swelling following iv administration have occurred. Among these events, 
the following have been identified as adverse drug reactions (identified risks): injection site 
erythema, administration site pain, injection site pain, injection site pruritus, and injection site 
dermatitis. None of these identified risks are considered important risks. 
Infusion-related reaction and drug hypersensitivity were also identified as adverse drug reactions. 
To date, 1 subject who received fremanezumab iv had a non-serious infusion-related reaction, 
and 1 patient who received fremanezumab via the sc route had a non-serious event of drug 
hypersensitivity. Both events resolved following IMP discontinuation and treatment with 
diphenhydramine and methylprednisolone. Neither of these identified risks are considered 
important risks. 
Potential risks for TEV-48125 include 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.

medicinal product (IMP), ie, based on week 0 to 12 data. 
A secondary objective of this 
study is to further demonstrate 
the efficacy of fremanezumab 
in the prevention of CCH in 
adult patients. 
The secondary efficacy endpoints to further demonstrate 
efficacy are: 
• the proportion of patients with a ≥50% reduction 
from baseline (run-in period) in the monthly 
average number of CH attacks over the 12-week 
period after the administration of the first dose of 
the IMP, ie, based on week 0 to 12 data 
• the mean change from baseline (run-in period) in 
the number of CH attacks during the 4-week period 
after administration of the first dose of the IMP, 
ie, based on week 0 to 4 data 
• the mean change from baseline (run-in period) in 
the number of CH attacks during the 4-week period 
after administration of the third dose of the IMP, 
ie, based on week 8 to 12 data 
• the mean change from baseline (run-in period) in 
the weekly average number of days with use of 
cluster-specific acute headache medications 
(triptans and ergot compounds) during the 12-week 
period after administration of the first dose of the 
IMP, ie, based on week 0 to 12 data 
• the mean change from baseline (run-in period) in 
the weekly average number of days oxygen is used 
to treat CCH during the 12-week period after 
administration of the first dose of the IMP, ie, based 
on week 0 to 12 data 
• assessment of patient’s perceived improvement, as 
measured by the Patient-Perceived Satisfactory 
Improvement (PPSI) at 1, 4, 8, and 12 weeks after

Objectives 
Endpoints 
administration of the first dose of the IMP relative 
to baseline (day 0) 
A secondary objective of this 
study is to evaluate the safety 
of fremanezumab in adult 
patients with CCH.  
The secondary safety endpoints are as follows: 
• occurrence of adverse events throughout the study 
• clinical laboratory (serum chemistry, hematology, 
coagulation, and urinalysis) test results at each visit 
• vital signs (systolic and diastolic blood pressure, 
oral temperature, and pulse rate) measurements at 
each visit. Note: Oxygen saturation will be 
measured in cases of suspected anaphylaxis and 
severe hypersensitivity. Respiratory rate will also 
be measured in these cases but not as a standard 
vital sign. 
• 12-lead electrocardiogram (ECG) findings at 
screening, baseline, and week 12 
• use of concomitant medication during the study 
• clinically significant changes in physical 
examinations, including body weight  
• injection site reaction (ie, erythema, induration, and 
ecchymosis) and injection site pain assessments  
• occurrence of hypersensitivity/anaphylaxis 
reactions 
• suicidal ideation and behavior as measured by the 
electronic Columbia Suicide Severity Rating Scale 
(eC-SSRS) 
The immunogenicity 
objective is to evaluate the 
immunogenicity of 
fremanezumab and the impact 
of antidrug antibodies (ADAs) 
on clinical outcomes in patients 
exposed to iv and sc 
fremanezumab 
The immunogenicity endpoints are ADA incidence and 
characteristics (eg, titer, kinetics, and neutralizing activities) 
2.1.1. 
Justification of Primary Endpoint 
For patients with CCH, headache attacks occur for more than 1 year without remission, or with 
remission periods lasting less than 1 month (May 2005). The duration of pain in these patients 
supports the need to evaluate time point of the primary endpoint of 12 weeks. This longer 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057

duration of assessment at 12 weeks in CCH patients should capture the effect on fluctuations in 
frequency of headaches within the clusters.

STUDY DESIGN 
3.1. 
General Design and Study Schematic Diagram 
This is a 16-week, multicenter, randomized, double-blind, double-dummy, placebo-controlled, 
parallel-group study to compare the efficacy and safety of 2 dose regimens of fremanezumab 
versus placebo in adult patients for the prevention of CCH. The study will consist of a screening 
visit, a run-in period lasting approximately 4 weeks (+3 days), and a 12-week double-blind 
treatment period. During the course of any CH attack, patients will be allowed to use acute 
medications to treat acute headaches, as needed (PRN). 
Patients will complete a screening visit (visit 1) after providing written informed consent, and 
eligible patients will enter a run-in period lasting at least 4 weeks (+3 days) during which they 
will enter baseline CH attack information into an electronic diary device daily. Patients will 
return to the study center after completing the run-in period (visit 2 [week 0]). Patients who have 
at least 10 CH attacks during the run-in period and who continue to meet eligibility criteria 
(including entry of CH attack information in an electronic diary demonstrating compliance for 
85% of days during the run-in period) will be randomly assigned at visit 2 (week 0) in a 
1:1:1 ratio to 1 of 3 treatment groups as follows: 
• fremanezumab 900-mg iv loading dose group: fremanezumab at 900 mg administered 
via an approximately 1-hour iv infusion at visit 2 (week 0) followed by 
fremanezumab at 225 mg administered as single sc injections (225 mg/1.5 mL) at 
visits 3 and 4 (weeks 4 and 8, respectively) 
• fremanezumab 675-mg sc loading dose group: fremanezumab at 675 mg administered 
as 3 sc injections (225 mg/1.5 mL) at visit 2 (week 0) followed by fremanezumab at 
225 mg administered as single sc injections (225 mg/1.5 mL) at visits 3 and 4 
(weeks 4 and 8, respectively) 
• placebo group: placebo administered via an approximately 1-hour iv infusion and as 
3 sc injections at visit 2 (week 0) followed by placebo administered as single sc 
injections at visits 3 and 4 (weeks 4 and 8, respectively) 
In order to maintain blinding throughout the study, the number of infusions and injections at each 
visit will be the same for all patients regardless of the treatment group to which they are 
randomized. Thus, all patients will receive an iv infusion of the test IMP or placebo IMP 
followed by 3 sc injections of the test IMP or placebo IMP at visit 2 (week 0), and all patients 
will receive single sc injections of the test IMP or placebo IMP at visits 3 and 4 (weeks 4 and 8, 
respectively). 
Randomization will be performed using electronic interactive response technology (IRT). 
Patients will be randomly assigned with stratification based on sex, country, and baseline 
concomitant preventive medications (yes/no) to the fremanezumab 900-mg iv loading dose 
group, the fremanezumab 675-mg sc loading dose group, or the placebo group in a 1:1:1 ratio.  
Blinded treatment will be administered once monthly (ie, approximately every 4 weeks) for a 
total of 3 months. Final study assessments will be performed at the final visit for this study 
(visit 5), approximately 12 weeks after administration of the first dose of the IMP. Upon 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
43 
completion of the final study assessments, early withdrawal from the study, or discontinuation 
for any reason, patients will be offered the opportunity to enter a 32 week long-term safety study 
(as described in Study TV48125-CNS-30058) for safety and ADA evaluation without additional 
dosing. 
Patients who satisfactorily complete the study may be offered to enroll the long-term safety 
Study TV48125-CNC-30058 for 68 weeks (as described in this study protocol) to receive 
additional dosing and a final follow-up visit for safety and ADA evaluation. In any case, during 
the period of the long-term safety study, where patients are not receiving additional dosing (and 
are waiting for ADA evaluation), these patients should be treated with standard of care as 
appropriate. A separate protocol was issued for the long-term safety study. 
CH attack information will be captured daily during the double-blind treatment period using an 
electronic diary device. Assessments of change in quality of life and health status (using the 
Hospital Anxiety and Depression Scale [HADS], EuroQol-5 Dimension [EQ-5D] questionnaire, 
12-Item Short-Form Health Survey [SF-12], Impact on Partner and Family questionnaire, and 
Work Productivity and Activity Impairment [WPAI] questionnaire); satisfaction with treatment 
(using the PPSI and Patient Global Impression of Change [PGIC] scale); safety evaluations 
(including eC-SSRS); blood collection for pharmacokinetics, immunogenicity, biomarker, and 
pharmacogenomics (unless not allowed per local regulation) analyses; and urine sampling for 
biomarker analysis will be performed at prespecified time points.  
The end of study is defined as the last visit of the last patient. 
The study duration will be approximately 24 months from Q4/2016 to Q3/2018. 
The study schematic diagram is presented in Figure 1.

Note: Patients randomized to the 900-mg iv loading dose group will receive 900 mg of fremanezumab administered 
via an approximately 1-hour iv infusion followed by 3 placebo sc injections at visit 2 (week 0) and fremanezumab at 
225 mg administered as single sc injections at visits 3 and 4 (weeks 4 and 8, respectively). Patients randomized to 
the 675-mg sc loading dose group will receive placebo administered via an approximately 1-hour iv infusion and 
fremanezumab at 675 mg administered as 3 sc injections (225 mg/1.5 mL) at visit 2 (week 0) and fremanezumab at 
225 mg administered as single sc injections at visits 3 and 4 (weeks 4 and 8, respectively). Patients randomized to 
the placebo group will receive placebo as an approximately 1-hour iv infusion followed by placebo administered as 
3 placebo sc injections at visit 2 (week 0) and placebo as single sc injections at visits 3 and 4 (weeks 4 and 8, 
respectively).  
Wearable Sensor Substudy: A subset of patients in selected investigational sites will be offered 
the opportunity to participate in a substudy to understand the utility of physiological biomarker 
measures captured through wearable digital sensor devices as tools to monitor response to 
treatment and disease symptoms (eg, activity/sleep disruption). Refer to Section 8.6 for 
additional details. 
3.2. 
Planned Number of Patients and Countries 
A total of approximately 300 patients (approximately 100 patients per treatment group) are 
planned to be enrolled in this study. Details on the definition of evaluable patients and sample 
size are given in Section 9. 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
45 
The study is planned to be conducted in approximately 12 countries in approximately 
80 investigational centers. The study is expected to start in Q4/2016 and last until approximately 
Q3/2018. 
3.3. 
Justification for Study Design and Selection of Population 
The study design follows the recommendations of the IHS guidelines for controlled trials of 
drugs in CH (Lipton et al 1995), which specify that clinical trials of prophylactic drugs for CH 
should be parallel-group, placebo-controlled studies in patients meeting the diagnostic criteria set 
forth by the International Classification of Headache Disorders, third revision beta (ICHD 3-
beta) for CCH (Headache Classification Committee of the IHS 2013). Also consistent with the 
IHS guidelines, patients will be randomized with stratification based on gender (Lipton et al 
1995). 
The study population will be composed of male and female patients, aged 18 to 70 years, 
inclusive, with a history of CCH (as defined by ICHD 3-beta criteria [Headache Classification 
Committee of the IHS 2013]) for at least 12 months prior to screening.  
CH is an intensely painful primary headache disorder, and there is a significant unmet medical 
need for preventive treatments for CH. 
3.4. 
Stopping Rules for the 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 centers to identify safety concerns. 
The study may be terminated by the sponsor for any reason at any time. For example, the 
sponsor should terminate the study in the event the following conditions happen: 
• new toxicological or pharmacological findings or safety issues invalidate the earlier 
positive benefit-risk assessment 
• development of the IMP is discontinued 
• the interim analysis (performed when 50% of patients have completed 12-week 
assessments during the double-blind study period or have withdrawn from the study 
early) supports stopping early for futility 
A patient may discontinue participation in the study at any time for any reason (eg, lack of 
efficacy, consent withdrawn, or adverse event). The investigator and/or sponsor can withdraw a 
patient from the study at any time for any reason (eg, lack of efficacy, protocol deviation as 
defined in Section 10, noncompliance, or adverse event). In addition, patients with positive 
eC-SSRS findings or abnormal hepatic laboratory values (eg, alanine aminotransferase [ALT], 
aspartate aminotransferase [AST], alkaline phosphatase [ALP], gamma-glutamyl transpeptidase 
[GGT], bilirubin [total, direct, and indirect], or international normalized ratio [INR]) may meet 
criteria for discontinuation from the IMP as summarized in Appendix J. 
Patients who are discontinued early for any reason will be offered the option to enroll in 
Study TV48125-CNS-30058 for the purpose of evaluating ADAs and safety (adverse events and 
concomitant medications).

j Women of childbearing potential only. 
k Postmenopausal women only. 
l Eligible patients will be given an electronic diary device and will be trained in its use and compliance requirements on the day of screening.  
m Patients will enter CH attack information (ie, occurrence and number of CH attacks, duration of CH attack[s], severity of CH attack[s], and acute CH-specific 
medication and oxygen use) into the electronic diary device beginning on the day after the screening visit through the EOT/early withdrawal visit. 
n Unless the patient begins participation in the long-term safety study (Study TV48125-CNS-30058) on the same day (ie, after completing all 
assessments/procedures for this visit). 
o The blood sample for pharmacokinetics analysis collected at visit 2 (week 0) prior to dosing (from either arm) and at the end of the infusion (+10 minutes) from 
the arm that is not used for the IMP infusion. All other blood samples for pharmacokinetics analysis will be collected prior to dosing (where applicable) and 
may be collected from either arm. 
p Blood samples for serum ADA assessment (5 mL) will also be collected upon observation of any severe hypersensitivity reaction and anaphylaxis. Patients 
who will not enroll in the double-blind, long-term safety study for treatment, for any reason, will be offered the option to enter the long-term safety study for 
the purpose of evaluating ADAs and safety (adverse events and concomitant medications) approximately 7.5 months after administration of the last dose of 
IMP in this study. 
q A blood sample for pharmacogenomic analysis will be collected at visit 2 (week 0) or any visit thereafter, unless the patient declines testing or local regulations 
prohibit testing. 
r Blood for further biomarkers analyses will be collected after blood collection for pharmacokinetic and immunogenicity analyses as follows: 8.5 mL for serum, 
6 mL for plasma, and 2.5 mL for PAXgene® RNA. 
s Responses will be recorded in the investigational site tablet. 
t Partners/family members will be asked to attend the study visit with the patient or to return to the investigational center within ±3 days of the patient’s visit if 
unable to appear at the same time. 
u Responses at week 1 will be recorded in the electronic diary device at home, and responses at all other time points will be entered into the investigational site 
tablet. 
v Patients will return the wearable sensor if they do not rollover into the long-term safety study (Study TV-48125-CNS-30058) or if they rollover into the 
long-term safety study but do not wish to continue participating in the wearable sensor substudy. 
w The eC-SSRS Baseline/Screening version will be completed at visit 1, and the eC-SSRS Since Last Visit version will be completed at all other visits, including 
unscheduled visits. Results from both versions will be entered into the investigational site tablet. 
x Patients randomized to the 900-mg iv loading dose group will receive 900 mg of fremanezumab administered via an approximately 1-hour iv infusion followed 
by 3 placebo sc injections at visit 2 (week 0) and fremanezumab at 225 mg administered as single sc injections at visits 3 and 4 (weeks 4 and 8, respectively). 
Patients randomized to the 675 mg sc loading dose group will receive placebo administered via an approximately 1-hour iv infusion followed by fremanezumab 
at 675 mg administered as 3 sc injections (225 mg/1.5 mL) at visit 2 (week 0) and fremanezumab at 225 mg administered as single sc injections at visits 3 and 4 
(weeks 4 and 8, respectively). Patients randomized to the placebo group will receive placebo as an approximately 1-hour iv infusion followed by placebo 
administered as 3 placebo sc injections at visit 2 (week 0) and placebo as single sc injections at visits 3 and 4 (weeks 4 and 8, respectively).  
y Patients will be assessed for hypersensitivity reactions and anaphylaxis during and after administration of the IMP (through 1 hour postdose).

opinion could interfere with the study evaluations or the patient’s safety. 
4.3. 
Withdrawal Criteria and Procedures 
Each patient is free to withdraw from the IMP and/or study at any time, without prejudice to their 
continued care. Patients must be withdrawn from the IMP and/or study if any of the following 
events occur: 
1. Patient withdraws consent or requests discontinuation from the IMP and/or study for any 
reason. 
2. Patient develops an illness that would interfere with his/her continued participation. 
3. Patient is noncompliant with the study procedures and assessments or administration of 
IMPs in the opinion of the investigator. 
4. Patient takes prohibited concomitant medications as defined. 
5. A female patient has a confirmation of pregnancy during the study from a positive 
pregnancy test. 
6. The sponsor requests withdrawal of the patient. 
7. Patient experiences an adverse event or other medical condition which indicates to the 
investigator that continued participation is not in the best interest of the patient. 
8. The investigator and/or sponsor may withdraw an individual patient from the study at any 
time for any reason (eg, lack of efficacy, protocol deviation as defined in Section 10, 
noncompliance, or adverse event). In addition, patients with positive eC-SSRS findings 
or abnormal hepatic laboratory values (eg, ALT, AST, ALP, GGT, bilirubin [total, direct, 
or indirect], or INR) may meet criteria for discontinuation from the IMP as summarized 
in Appendix J. 
In the event that a patient was incorrectly randomized and has already started taking the study 
drug, a risk/benefit evaluation should take place between the investigator and sponsor and a 
strong clinical justification must be provided if the patient is not withdrawn from study drug. 
Patients should be treated with standard of care after withdrawal from or termination of the study 
as appropriate. 
Investigators should attempt to obtain information on patients in the case of withdrawal or 
discontinuation. Results of any evaluations and observations, together with a narrative describing 
the reason(s) for withdrawal, must be recorded in the source documents. The case report form 
(CRF) must document the primary reason for withdrawal or discontinuation. 
See Appendix F for information regarding how the study will define and address lost to 
follow-up patients to help limit the amount and impact of missing data. 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
56 
If a patient is withdrawn from the study for multiple reasons that include also adverse events, the 
termination page of the CRF should indicate that the withdrawal was 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 that requires the use of a 
prohibited medication, thereby requiring discontinuation of the patient. In such a case, the reason 
for discontinuation would be “need to take a prohibited medication” and not the adverse event. 
Should a patient decide to withdraw after administration of the IMP 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 the study must be recorded on the source 
documentation and transcribed to the CRF. If a patient withdraws consent, every attempt will be 
made to determine the reason.  
All protocol-specified procedures/assessments should be performed at the early withdrawal visit 
(see Appendix B). Patients who withdraw from the study will not be replaced. Patients who 
withdraw early will be offered the opportunity to enter the long-term safety study (Study 
TV48125-CNS-30058) for the purpose of evaluation of ADAs and safety (adverse events and 
concomitant medications) approximately 7.5 months after administration of the last dose of IMP 
in this study. These patients will not receive any doses of fremanezumab after completing 
participation in the current study and should be treated with standard of care as appropriate. 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). In the case of patients lost to follow-up, attempts to contact the patient must 
be made and documented in the patient’s medical records and transcribed to the CRF. 
4.4. 
Replacement of Patients 
A patient who is randomized/enrolled but does not complete the treatment period will not be 
replaced with another eligible patient. 
4.5. 
Rescreening 
A patient who is screened and does not meet study inclusion and exclusion criteria will not be 
considered for screening again. 
4.6. 
Screening Failure 
Screening failures are defined as participants who consent to participate in the clinical study but 
are not subsequently randomized/enrolled in the study. Minimal information includes but is not 
limited to demography, screening failure details, eligibility criteria, and any adverse events or 
serious adverse events.

IMP=investigational medicinal product; iv=intravenous; n/a=not applicable; sc=subcutaneous. 
Administration of IMP will be via the iv and sc routes. At visit 2, IMP (test or placebo) will be 
administered via an approximately 1-hour iv infusion followed by 3 sc injections of IMP (test or 
placebo). At visits 3 and 4, IMP (test or placebo) will be administered as single sc injections. The 
recommended sc injection sites follow the National Institutes of Health Patient Education 
Guidelines of September 2015, which are available in Appendix U of this document and at the 
following 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. At 
each visit, the injections 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 through 4, test or placebo). A 1.5-mL volume from each 
prefilled syringe must be injected sc for dosing to be considered complete. 
5.1.1. 
Test Investigational Medicinal Product 
Fremanezumab is a fully humanized IgG2a/kappa monoclonal antibody derived from a murine 
precursor. Fremanezumab for CH is being developed for iv and sc administration.  
Additional details may be found in Table 3 and in the IB for fremanezumab.  
5.1.1.1. 
Starting Dose and Dose Levels 
Patients randomized to receive fremanezumab will receive either 900 mg or 675 mg. At visit 2 
(week 0), iv administration of treatment (IMP or placebo) will precede sc administration (IMP or 
placebo). Patients randomized to the 900-mg iv loading dose group will receive 900 mg of 
fremanezumab as an approximately 1-hour iv infusion followed by 3 placebo sc injections at 
visit 2 (week 0) and fremanezumab at 225 mg administered as single sc injections 
(225 mg/1.5 mL) at visits 3 and 4 (weeks 4 and 8, respectively). Patients in the 675-mg sc dose 
group will receive placebo as an approximately 1-hour iv infusion followed by fremanezumab at 
675 mg administered as 3 sc injections (225 mg/1.5 mL) at visit 2 (week 0) and fremanezumab at 
225 mg administered as single sc injections at visits 3 and 4 (weeks 4 and 8, respectively).  
5.1.2. 
Placebo Investigational Medicinal Product 
The placebo will be the same vehicle and excipients as those for fremanezumab. See Table 3 for 
additional details. Patients randomized to the placebo group will receive placebo administered 
via an approximately 1-hour iv infusion followed by placebo as 3 sc injections at visit 2 (week 0) 
and placebo administered as single sc injections at visits 3 and 4 (weeks 4 and 8, respectively). 
5.2. 
Preparation, Handling, Labeling, Storage, and Accountability for 
Investigational Medicinal Products 
Information pertaining to the preparation, handling, labeling, storage, and accountability for the 
IMP used in this study can be found in Appendix G. 
5.3. 
Justification for Investigational Medicinal Products 
5.3.1. 
Justification for Dose of Test Investigational Medicinal Product 
The fremanezumab doses, regimens, and routes of administration to be evaluated in this 
double-blind, double-dummy, placebo-controlled study were selected on the basis of 3 key 
factors. First, simulations suggest that Cmax is the most significant pharmacokinetic parameter in 
the efficacy of fremanezumab (in migraine). As CH is considered one of the most severe forms 
of pain a person can experience, treatments that provide quick and lasting relief (ie, for the 
duration of the cluster period) are a priority for this patient population. Second, the biological 
nature of the disease mandates the need for any treatment to desensitize the third order neuron, 
not the second (as is the case in migraine), suggesting that high levels of blockade at the first 
neuron would be necessary. Third, the favorable safety profile of the drug, as well as clinical and 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
59 
nonclinical safety data on exposure, suggest that the proposed doses, regimens, and routes of 
administration will not present any safety concerns. 
In the current study, high doses are planned for the first dose (900 mg iv or 675 mg sc) in order 
to provide a rapid response, especially following iv infusion where higher peak plasma Cmax 
generally occurs at or shortly after the end of infusion compared with 5 to 7 days postdose for sc 
injections. The 2 forms of loading dose will provide data to confirm the benefit of either the iv or 
sc as loading dose. Monthly doses of fremanezumab at 225 mg sc were added to both the initial 
dose of 900 mg iv and 675 mg sc for maintenance of efficacy. Based on modelling, the inclusion 
of a loading dose should allow patients to reach steady state faster. The monthly doses of 225 mg 
sc in this CCH population will account for the continuous attacks, with less than 1 month free of 
headaches between attacks, seen with this CH form. 
5.3.2. 
Justification for Use of Placebo Investigational Medicinal Product 
A placebo-controlled design is appropriate given the purpose and objectives of this clinical 
study. Inclusion of a placebo control group is consistent with the IHS guidelines for controlled 
trials of drugs in CH, first edition (Lipton et al 1995). 
5.4. 
Treatment after the End of the Study 
Patients who successfully complete the final visit of this study may be offered the opportunity to 
enroll in the long-term safety extension study (Study TV48125-CNS-30058), which includes a 
treatment period lasting approximately 40 weeks.  
Patients who were discontinued early for any reason or who do not enroll in this long-term study 
for treatment, for any reason, will be offered the option to enter the study for the purpose of 
evaluating ADAs and safety (adverse events and concomitant medications) at approximately 
7.5 months after administration of the last dose of the IMP. These patients will not receive any 
doses of fremanezumab after completing participation in the current study and should be treated 
with standard of care as appropriate. 
5.5. 
Restrictions 
Patients will be required to comply with the following restrictions: 
5.5.1. 
Activity 
Patients must remain at the investigational site, for safety observation, at least 60 minutes after 
infusion or according to medical judgment.  
5.5.2. 
Blood Donation 
Patients may not donate blood while taking the IMP and for 5 half-lives (7.5 months) after the 
last dose of the IMP. 
5.5.3. 
Pregnancy 
Restrictions related to pregnancy and required laboratory values (ie, serum and urine β-HCG 
tests) are provided in the inclusion and exclusion criteria (Section 4.1 and Section 4.1, 
respectively). Restrictions in regard to contraception methods are reviewed in Appendix E.

5.6. 
Prior and Concomitant Medication or Treatment 
Any prior or concomitant medication, treatment, or procedure a patient has had 3 months before 
screening visit (visit 1) and up to the end of study, including follow-up, will be recorded on the 
CRF. Trade name and INN (if available), indication, dose, and start and end dates of the 
administered medication will be recorded. The sponsor will encode all medication and treatment 
according to the World Health Organization (WHO) drug dictionary (WHO Drug). 
A maximum of 2 concomitant preventive medications for CCH are allowed. Patients must be on 
a stable dose and regimen for at least 2 weeks prior to screening and throughout the study. A list 
of permissible preventive medications is provided in Appendix H. 
For daily prescribed medications, patients must be on a stable dose and regimen for at least 
2 weeks prior to screening and throughout the study. 
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 visit. 
5.7. 
Procedures for Monitoring Patient Compliance 
The investigator will be responsible for monitoring patient compliance. A check of compliance 
with IMP intake will be performed during each visit after the IMP has been administered, and 
IMP accountability records will be completed. 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 from the study. Exposure to IMP will be 
assessed as required. 
5.8. 
Randomization and Blinding 
This is a randomized, double-blind, double-dummy, placebo-controlled study. Patients and 
investigators will remain blinded to IMP assignment during the study. 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 prefilled syringes with test IMP or 
placebo IMP. Adequate kit supply for upcoming study visits will be managed by IRT and kept 
(refrigerated at 2°C to 8°C) on site. 
Patients will be randomly assigned with stratification based on gender, country, and baseline 
concomitant preventive medication use (yes/no) to the fremanezumab 900-mg iv loading dose 
group, the fremanezumab 675-mg sc loading dose group, or the placebo group in a 1:1:1 ratio. 
The sponsor, investigators, study staff (except for staff involved in bioanalytical analyses and 
interim analyses [by a third-party, unblinded statistician]), and patients will be blinded to 
treatment assignment throughout the study. 
The IRT will manage initial drug supply, maintenance of adequate IMP supplies on site, and 
study randomization centrally.

Maintenance of Randomization and Blinding 
5.9.1. 
Maintenance of Randomization 
The randomization code will be generated by the IRT third-party vendor, following 
specifications from the Biostatistics Department. A Teva statistician will be responsible for 
reviewing the dummy randomization codes, and the final randomization code will be maintained 
by the third-party vendor in a secure location. 
At the time of analysis (after the end of the study), after receiving an unblinding request from the 
Teva statistician, the service provider will provide the unblinded IMP assignments according to 
the processes defined in the relevant Standard Operating Procedure (SOP). 
5.9.2. 
Blinding and Unblinding 
Blinded pharmacokinetics data may be assessed during the study. Personnel responsible for 
bioanalysis (pharmacokinetics and immunogenicity) will be provided with the randomization 
code to facilitate the analysis. However, the personnel responsible for bioanalysis and 
pharmacokinetics 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 the concentration data of an individual 
patient). 
The planned interim analysis (Section 9.15) will be conducted by a third-party, unblinded 
statistician. Results from the interim analysis will be reported in a manner that does not unblind 
any blinded individuals (ie, the sponsor, investigators, blinded study staff, and patients). 
For information about personnel who may be aware of IMP assignments, see Section 5.8. 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, pregnancy, or in cases when knowledge of the treatment 
assignment is needed to make treatment decisions, the investigator may unblind the patient’s 
IMP assignment as deemed necessary, mainly in emergency situations, through specialized 
access in the IRT system. If possible, the sponsor should be notified of the event before breaking 
of the code. If this is not possible, the sponsor should be notified immediately afterwards, and the 
patient’s randomization code should not be revealed. In emergency cases, breaking of the 
randomization code can be performed by the investigational center without prior approval by the 
sponsor. 
In the event that the IRT system is not functioning for emergency unblinding, the next course of 
action is to contact via phone the IRT on-call customer support helpline for manual emergency 
unblinding.  
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 an adverse event defined as a suspected unexpected serious adverse 
reaction (SUSAR) (ie, reasonable possibility; see Section 7.1.4), Global Patient Safety and

Pharmacovigilance may independently request that the treatment code be broken (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 of the study, and analysis and 
reporting of the data. 
5.9.3. 
Data Monitoring Committee 
There will be no Data Monitoring Committee for this study. 
5.10. 
Total Blood Volume 
The total blood volume to be collected for each patient enrolling in this study is approximately 
131.5 mL for scheduled tests. An additional 30 mL of blood may be collected in the event of 
follow-up for liver enzymes as detailed Appendix J. 
Details are provided in Appendix L.

ASSESSMENT OF EFFICACY 
Data from any efficacy assessments performed after the specified time will not be collected on 
the CRF. However, in the event that such data are collected, these data will not be analyzed. 
6.1. 
Electronic Diary Device 
Efficacy endpoints related to CH attacks will be derived from data collected daily using an 
electronic diary device. Eligible patients will receive comprehensive training at screening from 
the investigational site personnel on the use of the electronic diary device. Investigational site 
personnel will also instruct patients on the requirement for timely and daily completion of the 
electronic diary.  
Patients will complete electronic headache diary entries with questions about the previous day, 
starting from the day after the screening visit through the end of treatment (EOT)/early 
withdrawal visit. The electronic headache diary device will allow entry of headache information 
for up to 2 days after a given day. 
Patients who report a CH attack will answer questions about the attack (ie, occurrence and 
number of CH attacks, duration of CH attack[s], severity of CH attack[s], and acute CH-specific 
medication and oxygen use). The last day of the run-in period should be reported in the morning 
of the visit day. 
Patients will be asked about their performance at work or at school on CH attack-free days. 
Additional details can be found in the electronic diary device 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 2 days have elapsed since completion of that day. If more than 2 days 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.  
If a CH is reported, then CH intensity will be subjectively rated by the patient as follows: 
• Mild 
• Moderate 
• Severe 
• Very severe 
6.2. 
Hospital Anxiety and Depression Scale  
The HADS is a validated and reliable, 14-item scale developed by by Zigmond and Snaith 
(1983) to measure anxiety (7-items) and depression (7-items). Each item is scored on a 4-point 
scale from 0 to 3. Scores for depression and anxiety range from 0 to 21; a score of 0 to 7 is 
normal, 8 to 10 is borderline abnormal, and 11 to 21 is abnormal. 
Patients will complete the HADS in the investigational site tablet at the time points detailed in 
Table 2.

6.3. 
EuroQol-5 Dimension Questionnaire 
The 5 level EQ-5D (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 in the investigational site tablet at the time points detailed 
in Table 2. 
6.4. 
Twelve-Item Short-Form Health Survey 
The SF-12 (version 2) is a generic health survey containing 12 questions to measure functional 
health and well-being rated in 8 health domains (physical function, role limitations due to 
physical problems, bodily pain, general health perceptions, vitality, social functioning, role 
limitations due to emotional problems, and mental health) with 1 or 2 questions per domain. The 
SF-12 was developed from the 36-Item Short-Form Health Survey (Ware et al 1996). Scores 
range from 0 to 100, with higher scores indicating better health status.  
Patients will complete the SF-12 in the investigational site tablet at the time points detailed in 
Table 2. 
6.5. 
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 in the investigational site tablet at the time points 
detailed in Table 2. 
6.6. 
Impact on Partner and Family Questionnaire 
The partners/family members of patients participating in the study, if applicable, will complete 
an Impact on Partner and Family questionnaire at the time points detailed in Table 2. Responses 
will be recorded in the investigational site tablet. The questionnaire will include questions about 
the impact of CH on the patient’s ability to do chores, the number of days that the patient missed 
a family or social activity since the last assessment due to CH, and the frequency with which the 
patient avoids making plans for family/social activities due to CH. Partners/family members will 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
65 
be asked to attend the study visit with the patient or to return to the investigational center within 
±3 days of the patient’s visit if unable to appear at the same time.  
6.7. 
Patient-Perceived Satisfactory Improvement 
The PPSI was developed by ten Klooster et al (2006) for pain intensity and was adjusted for CH 
symptoms improvement. Patients will mark the level of CH-associated pain and indicate if pain 
is “much worse,” “moderately worse,” “slightly worse,” “unchanged,” “slightly improved,” 
“moderately improved,” or “much improved” compared with 4 weeks ago. PPSI will be defined 
as the change in pain that corresponds with a minimal rating of “slightly improved.” 
The PPSI will be completed in the electronic diary device at home at week 1 and in the 
investigational site tablet at the time points detailed in Table 2.  
6.8. 
Patient Global Impression of Change Scale 
The PGIC scale is a validated generic tool for the assessment of overall change in the severity of 
illness following treatment. Patients will rate the change in their overall health and wellbeing 
compared with how they felt at the start of the study (the time after the patient received the first 
IMP dose) as “much worse,” “moderately worse,” “slightly worse,” “stayed the same,” “a little 
better,” “moderately better,” or “much better.” 
Patients will record responses to the PGIC scale in the electronic diary device at home at week 1 
and in the investigational site tablet at the time points detailed in Table 2.

ASSESSMENT OF SAFETY 
In this study, safety will be assessed by qualified study personnel by evaluating reported adverse 
events, clinical laboratory test results, vital signs measurements, ECG findings, physical 
examination findings (including body weight measurements), injection site reaction/pain 
assessments, eC-SSRS scores, and use of concomitant medication. 
7.1. 
Adverse Events 
7.1.1. 
Definition of an Adverse Event 
Any untoward medical occurrence in a patient or clinical investigation subject administered a 
pharmaceutical product and which does not necessarily have to have a causal relationship with 
this treatment. 
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 
significant worsening of the disease under study, or of any concurrent disease, whether or not 
considered related to fremanezumab. 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 
• drug interactions 
• events occurring during diagnostic procedures or during any washout phase 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 treatment are not considered adverse 
events.) 
Medical occurrences that begin before dosing of the IMP but after obtaining informed consent 
will be recorded on the Medical History/Current Medical Conditions section of the CRF. 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
67 
7.1.2. 
Recording and Reporting of Adverse Events 
For recording of adverse events, the study period for this study is defined as the time period from 
signature of the ICF through the EOT/early withdrawal visit. Adverse events occurring after the 
EOT/early withdrawal visit for patients who enroll in the long-term safety study 
(Study TV48125-CNS-30058) will be recorded as part of the long-term safety study database. 
All adverse events that occur during the defined study period must be recorded on the source 
documentation and transcribed to the CRF, regardless of the severity of the event or judged 
relationship to the IMP. For serious adverse events and protocol-defined adverse events of 
special interest (see Section 7.1.7), the serious adverse event form must be completed and the 
serious adverse event or adverse event of special interest 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 and adverse events of special interest occurring 
in a patient 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, on the 
serious adverse event form. 
The clinical course of each adverse event will be monitored at suitable intervals until resolved, 
stabilized, or returned to baseline; or until the patient is referred for continued care to a health 
care professional; or until a determination of a cause unrelated to the IMP 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 IMP, treatment administered, and outcome for each adverse event must be 
recorded on the source documentation and transcribed to the CRF. 
The relationship of each adverse event to IMP and study procedures, and the severity and 
seriousness of each adverse event, as judged by the investigator, must be recorded as described 
below. 
Further details are given in the Safety Monitoring Plan 
7.1.3. 
Severity of an Adverse Event 
The severity of each adverse event must be recorded as 1 of the following: 
Mild: 
No limitation of usual activities 
Moderate: Some limitation of usual activities 
Severe: 
Inability to carry out usual activities 
For severity grading of local tolerability (injection site erythema, induration, ecchymosis, and 
pain), please refer to Section 7.11.

7.1.4. 
Relationship of an Adverse Event to the Test Investigational Medicinal Product 
The relationship of an adverse event to the test IMP is characterized as follows (Table 4): 
Table 4: 
The Relationship of an Adverse Event to the Test Investigational Medicinal 
Product 
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 IMP. 
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 IMP. 
• 
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 
IMP. 
• 
It does not reappear or worsen when the IMP 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 administration of IMP 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 IMP. 
• 
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 after 
discontinuation of the IMP, yet an IMP relationship 
clearly exists. 
• 
It follows a known pattern of response to the IMP. 
7.1.5. 
Serious Adverse Events 
For recording of serious adverse events, the study period is defined for each patient as that time 
period from signature of the ICF to the EOT/early withdrawal visit. Serious adverse events 
occurring in a patient after the EOT/early withdrawal visit should be reported to the sponsor if 
the investigator becomes aware of them, following the procedures described in Section 7.1.5.3.1. 
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: 
• results in death 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
69 
• is life-threatening adverse event (ie, the patient was at risk of death at the time of the 
event); it does not refer to an event which hypothetically might have caused death if it 
were more severe 
• requires inpatient hospitalization or prolongation of existing hospitalization, which 
means that hospital inpatient admission 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 before the patient signed the ICF will not be considered 
serious adverse events, unless there was worsening of the preexisting condition 
during the patient’s participation in this study. 
• results in persistent or significant disability/incapacity (refers to a substantial 
disruption of one’s ability to conduct normal life functions) 
• is 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. 
All occurrences of possible drug-induced liver injury that meet Hy’s law criteria, defined as all 
of the below, must be reported by the investigator to the sponsor as a serious adverse event 
(Appendix J): 
• ALT or AST increase of ≥3 × the ULN 
• total bilirubin increase of ≥2 × the ULN 
• absence of initial findings of cholestasis (ie, no substantial increase of ALP) 
• no other explanation for the observed abnormalities 
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 (RSI) by its specificity, severity, outcome, or frequency is 
considered an unexpected adverse event. The RSI for this study is the IB. 
The sponsor’s Global Patient Safety and Pharmacovigilance will determine the expectedness for 
all serious adverse events. 
For the purpose of SUSAR reporting, the version of the IB at the time of occurrence of the 
SUSAR applies.

Study TV48125-CNS-30057 
70 
7.1.5.3. 
Reporting a Serious Adverse Event 
7.1.5.3.1. Investigator Responsibility 
To satisfy regulatory requirements, all serious adverse events that occur during the study, 
regardless of judged relationship to administration of the test IMP, 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 to a patient after the last administration of IMP of that patient 
has ended 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 designee (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 and Pharmacovigilance. 
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 test IMP (no 
reasonable possibility, reasonable possibility) 
Additional information includes: 
• age and sex of patient 
• date of first dose of IMP 
• date and amount of last administered dose of IMP 
• action taken 
• outcome, if known 
• severity 
• explanation of assessment of relatedness 
• concomitant medication (including doses, routes of administration, and regimens) and 
treatment of the event 
• pertinent laboratory or other diagnostic test data 
• medical history 
• results of dechallenge/rechallenge, if known 
• for an adverse event resulting in death 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
71 
− cause of death (whether or not the death was related to IMP) 
− 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 test IMP, study 
procedures, and to underlying disease. 
Additional information (follow-up) about any serious adverse event unavailable at the initial 
reporting should be forwarded by the investigator 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 and Pharmacovigilance will distribute the 
Council for International Organizations of Medical Sciences (CIOMS) form/Extensible Markup 
Language (XML) file to the LSO/CRO for submission to the competent authorities, Independent 
Ethics Committee/Institutional Review Board (IEC/IRBs), and investigators, according to 
regulations. The investigator must ensure that the IEC/IRB is also informed of the event, in 
accordance with national and local regulations. 
For double-blind studies, blinding will be maintained for all study personnel. Therefore, in case 
of a SUSAR, only the LSO/CRO 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 test IMP or study 
procedures, the sponsor will take appropriate steps to notify all investigators participating in 
sponsored clinical studies of fremanezumab and the appropriate competent authorities (and 
IEC/IRB, as appropriate). 
In addition to notifying the investigators and competent authorities (and IEC/IRB, as 
appropriate), other action may be required, including the following: 
• altering existing research by modifying the protocol 
• discontinuing or suspending the study 
• modifying the existing consent form and informing all study participants of new 
findings 
• modifying listings of expected toxicities to include adverse events newly identified as 
related to fremanezumab 
7.1.6.

7.1.7. 
Protocol-Defined Adverse Events of Special Interest 
For purposes of this protocol, the following are considered protocol-defined adverse events of 
special interest to be sent to the sponsor’s Global Patient Safety and Pharmacovigilance 
Department for evaluation: ophthalmic related adverse events of at least moderate severity, 
events of possible drug-induced liver injury (AST or ALT ≥3 × the ULN, total bilirubin ≥2 × the 
ULN, or INR >1.5), Hy’s Law events, or events of anaphylaxis and severe hypersensitivity 
reactions. Refer to Appendix J for guidance regarding monitoring of patients with elevated liver 
function tests. Anaphylaxis and severe hypersensitivity 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 K). In the event of suspected anaphylaxis and severe 
hypersensitivity, vital signs, including oxygen saturation and respiration rate, will be measured. 
Other assessments will be performed at the discretion of the investigator. As a precaution, each 
site should have a resuscitation cart nearby. 
The process for reporting a protocol-defined adverse event of special interest is the same as that 
for reporting a serious adverse event (see Section 7.1.5.3). These events to be reported to the 
Global Patient Safety and Pharmacovigilance can be either serious or nonserious, according to 
the criteria outlined in Section 7.1.5.1. 
7.1.8. 
Protocol Deviations Because of an Adverse Event 
If a patient experiences an adverse event or medical emergency, deviations from the protocol 
may be warranted to ensure patient safety. After the event has stabilized or treatment has been 
administered (or both), the investigator or other physician in attendance must contact the 
physician 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. The same reporting 
process as for all other protocol deviations will apply. A noncompliant patient may continue 
taking the study treatment only if this does not jeopardize the patient’s safety. The sponsor will 
assess each protocol deviation and decide whether any of these noncompliances should be 
reported to the Regulatory Authority as a serious breach of Good Clinical Practice (GCP) and the 
protocol. 
7.2. 
Pregnancy 
Any female subject becoming pregnant during the study will discontinue IMP. All pregnancies 
of women participating in the study and female partners of men participating in the study, that 
occur during the study, or within at least 7.5 months after administration of the last dose of the 
IMP, 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 sponsor 
(LSO/CRO) with the completed pregnancy form. The process for reporting a pregnancy is the 
same as that for reporting a serious adverse event but using the pregnancy form (Section 7.1.5.3). 
The investigator is not required to report female subjects who are found to be pregnant between 
screening and baseline, provided no protocol-related procedures were applied. 
All female subjects or female partners of men participating in the study who become pregnant 
will be monitored for the outcome of the pregnancy (including spontaneous, elective, or 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
73 
voluntary abortion). Female partners of men participating in the study who become pregnant will 
be asked to sign an ICF. 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 withdrawal from the study will be reported as an 
adverse event or serious adverse event, as appropriate. 
If the pregnancy in the woman participating in the study and/or the female partners of men 
participating in the study 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.  
7.3. 
Medication Error and Special Situations Related to the 
Investigational Medicinal Products 
Any administration of IMP that is not in accordance with the study protocol should be reported 
as an important deviation, if it meets the important deviation criteria specified in the protocol 
(Appendix C), or as a deviation, in the patient’s source documents, regardless of whether or not 
an adverse event occurs as a result. When meeting important protocol deviation criteria, all 
instances of incorrect IMP administration should be reported in the clinical trial management 
system. A noncompliant patient may continue taking the study treatment only if this does not 
jeopardize the patient’s safety. 
The following are types of medication errors and special situations: 
1. Medication error: Any unintentional error in the prescribing, dispensing, or 
administration of a medicinal product while in the control of the healthcare professional, 
patient, or consumer. 
2. Overdose: Administration of a quantity of a medicinal product given per administration 
or cumulatively which is above the maximum recommended dose according to the 
authorized product information. Clinical judgment should always be applied. Any dose of 
IMP (whether the test IMP, reference IMP, or placebo IMP), whether taken intentionally 
or unintentionally, in excess of that prescribed must be immediately reported to the 
sponsor. When the identification of the IMP is required, the investigator must follow the 
procedures for unblinding outlined in Section 5.9.2.  
3. Misuse: Situations where the IMP is intentionally and inappropriately used not in 
accordance with the authorized product information. 
4. Abuse: Persistent or sporadic, intentional excessive use of IMP which is accompanied by 
harmful physical or psychological effects. 
5. Off-label use: Situations where an IMP is intentionally used for a medical purpose not in 
accordance with the authorized product information.

6. Occupational exposure: Exposure to an IMP, as a result of one’s professional or 
non-professional occupation. 
7. Breastfeeding: Suspected adverse reactions which occur in infants following exposure to 
a medicinal product from breast milk. 
7.4. 
Clinical Laboratory Tests 
All clinical laboratory test results outside of the reference range will be judged by the 
investigator as belonging to one of the following categories: 
• abnormal and not clinically significant 
• abnormal and clinically significant 
A laboratory test result that is judged by the investigator as clinically significant will be recorded 
on the source documentation and the CRF as an adverse event, and monitored as described in 
Section 7.1.2. An event may include a laboratory or diagnostic test abnormality (once confirmed 
by repeated testing) that results in the withdrawal of the patient from the study, the temporary or 
permanent withdrawal of IMP or medical treatment, or further diagnostic work-up. (Note: 
abnormal laboratory or diagnostic test results at the screening visit that preclude a patient from 
entering the study or receiving IMP are not considered adverse events.) 
In addition, potentially clinically significant values may be predefined by the sponsor for 
selected laboratory test variables and, if so, will be documented in the statistical analysis plan or 
other relevant documents (eg, medical monitoring plan or laboratory analysis plan). 
7.4.1. 
Serum Chemistry, Hematology, and Urinalysis 
Clinical laboratory tests (serum chemistry, hematology, and urinalysis) will be performed at the 
time points detailed in Table 2. Clinical laboratory tests will be performed using the central 
laboratory. However, in case of abnormal coagulation during screening (run-in period) or if other 
specific urgent tests are required, a local retest can be authorized by the sponsor or designee on a 
case-by-case basis. Specific laboratory tests to be performed are provided in Appendix M. 
7.4.1.1. 
Human Chorionic Gonadotropin Tests 
A serum β-HCG test will be performed for all WOCBP at screening (visit 1) and EOT (visit 5), 
and urine β-HCG tests will be performed for WOCBP at all other time points as specified in 
Table 2. Any female patient who becomes pregnant during the study will be withdrawn. 
Procedures for reporting the pregnancy are provided in Section 7.2. 
7.4.1.2. 
Follicle-Stimulating Hormone Tests 
Postmenopausal women will have a follicle-stimulating hormone test at screening (visit 1). 
7.5. 
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 2. 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 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
75 
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 in Section 7.1.2. 
7.6. 
Vital Signs 
Vital signs (blood pressure [systolic/diastolic], body temperature, and pulse) will be measured 
before other assessments (eg, blood draws and administration of questionnaires) at the time 
points detailed in Table 2. All vital signs results outside of the reference ranges will be judged by 
the investigator as belonging to one of the following categories: 
• abnormal and not clinically significant  
• abnormal and clinically significant 
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 7.6) and, if so, will be documented in the statistical analysis plan 
or other relevant documents (eg, medical monitoring plan). 
7.7. 
Electrocardiography 
Twelve-lead ECGs will be conducted before other assessments (eg, blood draws and 
administration of questionnaires) at the time points detailed in Table 2. The ECGs should be 
performed after the patient has been supine for at least 5 minutes. The ECGs will be performed 
in triplicate, with approximately 1 to 5 minutes between recordings.  
A qualified physician at a central diagnostic center will be responsible for interpreting the ECG. 
Electrocardiograms should be performed and transmitted according to the central ECG reading 
instructions provided in the ECG user manual. Electrocardiogram equipment will be provided to 
all clinical sites.  
Although the ECG interpretation will be performed centrally, the clinical evaluation remains 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). 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
76 
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. 
All ECG results outside of the reference ranges will be judged by the investigator as belonging to 
one of the following categories: 
• abnormal and not clinically significant  
• abnormal and clinically significant 
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 in the CRF, and monitored as described in Section 7.1.2. 
7.8. 
Immunogenicity 
Blood samples for serum ADA assessment will be collected at the time points detailed in 
Table 2. Blood samples for ADA assessment will also be collected upon observation of any 
severe hypersensitivity reaction and anaphylaxis. Bioanalytical personnel should be made aware 
of anaphylaxis occurrence as soon as possible in case an anti-fremanezumab IgE assay is needed. 
Patients who will not enroll in the double-blind, long-term safety study for any reason will be 
offered the option to enter the long-term safety study for the purpose of evaluating ADAs and 
safety (adverse events and concomitant medications) approximately 7.5 months after 
administration of the last dose of IMP.  
Samples from placebo-treated patients will not be analyzed unless the patient elects to enroll into 
the extension study where the patient will receive fremanezumab treatment. In this case the 
pre-dose (baseline) sample from the rolled-over placebo patient will be analyzed along with 
post-treatment samples collected in the extension study and reported in the extension study. 
7.9. 
Assessment of Suicidality 
The study population being administered fremanezumab should be monitored appropriately and 
observed closely for suicidal ideation and behavior or any other unusual changes in behavior. 
Consideration should be given to discontinuing fremanezumab in participants who experience 
signs of suicidal ideation or behavior. 
Families and caregivers of participants being treated with fremanezumab should be instructed to 
monitor participants for the emergence of unusual changes in behavior, as well as the emergence 
of suicidal ideation and behavior, and to report such symptoms immediately to the study 
investigator. 
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 1, and the eC-SSRS Since Last Visit version will be completed by the patient at 
every visit thereafter, including unscheduled visits. Any positive findings on the eC-SSRS Since 
Last Visit version requires evaluation by a physician or doctoral-level psychologist. 
A positive finding will be defined as a current suicide ideation with some intent to act and no 
plan. The investigator, based on his medical judgment, will determine if the patient should be 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
77 
seen by a mental health specialist and if he/she should continue participating in the study. If a 
patient reports current suicide ideation with specific plan and intent, then the patient should be 
immediately discontinued from the study and seen by a mental health specialist.  
Any patient should be excluded if any suicidal behaviors are reported. 
Any patient with lifetime behaviors (actual, interrupted, and aborted attempts and preparatory 
actions) should be excluded and/or discontinued from the study. 
7.10. 
Concomitant Therapy or Medication 
Concomitant therapy or medication use will be monitored throughout the study. Details of 
prohibited medications are found in Section 5.6.  
7.11. 
Injection Site Assessments 
Injection site assessments will be performed immediately (+10 minutes) and 1 hour (±15 
minutes) after receiving each dose of the IMP. The injection site(s) will be assessed for 
erythema, induration, and ecchymosis. 
Severity will be graded according to the following criteria: 
• Injection site erythema, induration, and ecchymosis will be graded according to 
measurements: absent, 5 to ≤50 mm (mild), >50 to ≤100 mm (moderate), and >100 
mm (severe). Induration must be assessed by careful superficial palpation avoiding 
pressuring or squeezing the injection site.  
• For spontaneous report of local pain after the injection, it will be measured as 
summarized in Table 5. 
Table 5:

If a patient has severe injection site induration, erythema, ecchymosis, or pain at 1 hour after 
completion of IMP administration, the patient will be reassessed at 3 hours (±15 minutes) after 
completion of IMP administration and hourly (±15 minutes) thereafter until the reaction 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 (injection site erythema, induration, ecchymosis, and pain) should be 
recorded as adverse events.

ASSESSMENT OF 
PHARMACOKINETICS/BIOMARKERS/PHARMACOGENOMIC
/IMMUNOGENICITY/ANCILLARY STUDIES 
8.1. 
Pharmacokinetics Assessment 
Sampling for pharmacokinetics will be sparse. Thus, the fremanezumab pharmacokinetics 
samples will be analyzed using a population pharmacokinetics approach and will be reported 
separately to the clinical study report.  
Blood samples (4 mL) will be collected via venipuncture/indwelling catheter at the time points 
detailed in Table 2 for plasma concentration measurements of fremanezumab. The dates and 
times of IMP administration and the date and time of each pharmacokinetics sample will be 
recorded on the source documentation and transcribed onto the CRF. 
Samples from patients who receive active IMP will be analyzed for concentration of 
fremanezumab using a validated method. Samples from patients who were randomized to receive 
placebo will not be analyzed. Details on sample handling, storage, shipment, and analysis are 
given in Appendix N.  
8.2. 
Pharmacodynamics Assessment 
Pharmacodynamics parameters are not evaluated in this study. 
8.3. 
Immunogenicity Testing 
Blood samples (5 mL) will be collected via venipuncture or indwelling catheter at the time points 
detailed in Table 2 for immunogenicity testing.  
Samples from patients who receive active IMP will be analyzed for ADA using a validated 
method. Samples from patients who receive placebo will not be analyzed unless the patient elects 
to enroll into an available extension study where the patient will receive fremanezumab 
treatment. In this case, the pre-dose (baseline) sample from the rolled-over placebo patient will 
be analyzed along with post-treatment samples collected in the extension study and values will 
be reported in the extension study. Details on sample handling, storage, shipment, and analysis 
are provided in Appendix O. 
8.4. 
Assessment of Exploratory Biomarkers 
Biomarkers are defined as biological substances that monitor physiological effects, assess drug 
activity, and predict clinical outcome, safety, and response to therapy. Details on sample 
handling, storage, shipment, and analysis are provided in Appendix P.  
CGRP-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 analysis may be conducted on 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
79 
blood (serum, plasma, and ribonucleic acid [RNA]) and urine biomarkers for 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 fremanezumab alters angiogenic markers. 
CGRP 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 fremanezumab in patients 
with CH. 
Based on the known biology of CGRP’s mechanism of action, biomarker assessment will 
potentially include markers of bone remodeling, inflammation, and angiogenesis. The validated 
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. 
8.5. 
Pharmacogenomics 
For information regarding pharmacogenomics assessments, see Appendix Q. Multiple genetic 
loci have been identified that could affect the binding affinity of the CGRP-receptor-ligand 
complex, while other genetic loci have been identified as having roles in migraine and/or 
headache onset (Anttila et al 2013). To explore the potential impact of normal variations in these 
loci on parameters in this study, a blood sample (6 mL) will be collected from each patient 
(unless the patient declines testing or local regulations prohibit testing) for pharmacogenomic 
assessment during this study. Pharmacogenomic assessment potentially includes the association 
analysis of both known and unknown DNA and RNA genetic variations. 
8.6. 
Ancillary Studies – Wearable Sensor Substudy 
At selected sites, a subset of patients (n=45, approximately 15 patients from each treatment 
group) will be asked to wear a sensor monitoring system (digital wearable device) on the wrist to 
track sleep patterns and activity patterns. The objective of this substudy is to evaluate changes in 
sleep-wake parameters and changes in activity as they relate to the occurrence of CH attacks. 
These changes will be evaluated during days when patients experience CH attacks relative to 
days free of attacks and will be evaluated for use as predictors of seasonal onset of new CH 
epoch. The relationship between sleep-wake parameters, activity levels, and the frequency, 
intensity, and duration of CH attacks will also be determined.  
Patients with CH describe their attacks to exhibit remarkable circadian and annual periodicity. 
The attacks are described to strike at predictable times of the day, mostly related to nocturnal 
sleep, and the clusters of these at specific times of the year (Barloese 2012, 2015, Rozen and 
Fishman 2012). CH attacks are also accompanied by systemic manifestations such as agitation 
and restlessness (Barloese 2015).  

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
80 
The data will be used to assess whether changes in patterns of sleep and/or activity as captured 
by the digital wearable device can be used for early prediction and possible intervention of CH 
attacks. It is anticipated that risks to patients beyond those listed in Section 1.3 are unlikely.  
Patients who are able to demonstrate appropriate use of the wearable device and are willing to 
comply with the requirements for use of the digital wearable device will be given the device and 
accessories at the baseline visit. The device will be worn continuously throughout the 12-week 
treatment period, and for patients who continue into the long-term safety study (Study TV48125-
CNS-30058), the device will be worn continuously throughout the 40-week treatment period of 
that study. Device checks and compliance checks will be done at the study center as described in 
the schedule of events shown in Table 2. The device will be collected at the time the patient 
discontinues from the study (ie, at the EOT visit if the patient will not continue participating in 
the substudy during the long-term safety study or at the early withdrawal visit).  
The digital wearable device is provided by Philips and will monitor activity during wake periods, 
which will be used to quantify relative activity. It will also monitor activity during sleep periods, 
which will be used to quantify sleep-wake parameters. Data will be obtained with an actigraphy 
device worn on the wrist. Motion data will be analyzed with either standard analysis techniques 
and/or advanced signal processing algorithms to extract the maximum amount of information 
from the data. Further information on the device and its use is provided in the substudy manual.

STATISTICS 
This section describes the statistical analysis as foreseen at the time of planning the study. 
Changes, additions, and further details about the analyses will be described in the statistical 
analysis plan. After finalization of the statistical analysis plan, any additional analyses or 
changes to analyses that may be required will be fully disclosed in the clinical study report. 
9.1. 
Sample Size and Power Considerations 
A sample size of 258 patients (86 evaluable patients completing the study per treatment group) 
will provide at least 90% power to detect a treatment difference of 4 CH attacks in the monthly 
average (assuming a common standard deviation [SD] of 8 CH attacks) at a 2-sided alpha level 
of 0.05. Assuming a 14% discontinuation rate, approximately 300 patients will be randomized in 
the trial. 
9.2. 
Analysis Sets 
9.2.1. 
Intent-to-Treat Analysis Set 
The intent-to-treat (ITT) analysis set will include all randomized patients. 
In the ITT analysis set, treatment will be assigned based on the treatment to which patients were 
randomized, regardless of which treatment they actually received. 
9.2.2. 
Safety Analysis Set 
The safety analysis set will include all randomized patients who receive at least 1 dose of IMP. 
In the safety analysis set, treatment will be assigned based on the treatment patients actually 
received, regardless of the treatment to which they were randomized, unless otherwise specified. 
9.2.3. 
Full Analysis Set 
The full analysis set will include all patients in the ITT analysis set who receive at least 1 dose of 
IMP and have at least 1 postbaseline efficacy assessment on the primary endpoint.  
9.2.4. 
Per-Protocol Analysis Set 
The per-protocol (PP) analysis set is a subset of the ITT analysis set including only patients 
without any important protocol deviations. Important protocol deviations will be determined 
before unblinding/database lock. 
In the PP analysis set, treatment will be assigned based on the treatment patients actually 
received, regardless of the treatment to which they were randomized.  
9.3. 
Data Handling Conventions 
Efficacy variables from patients who do not have diary entries completed for the entire study 
period will be imputed. Detailed data imputation rules will be described in the statistical analysis 
plan.

Handling Withdrawals and Missing Data 
Efficacy variables from patients who do not have diary data completed for the entire study period 
will be imputed. For the analyses based on the proportion of responders, patients who are 
terminated from the study early will be considered as nonresponders. For patients who complete 
the study and have intermittent missing days in the e-diary, data will be prorated to 7 days. 
Details will be provided in the statistical analysis plan. 
9.4. 
Study Population 
The ITT analysis set (see Section 9.2.1) will be used for all study population summaries unless 
otherwise specified. Summaries will be presented by treatment group and for all patients.

Data from patients screened; patients screened but not randomized and reason for not 
randomized; patients who are randomized; patients randomized but not treated; patients in the 
ITT, safety, and other analysis sets; patients who complete the study; and patients who withdraw 
from the study will be summarized using descriptive statistics. Data from patients who withdraw 
from the study will also be summarized by reason for withdrawal using descriptive statistics. 
9.4.2. 
Demographic and Baseline Characteristics 
Patient demographic and baseline characteristics, including medical history, prior medications 
and therapies, and ECG findings will be summarized using descriptive statistics. For continuous 
variables, descriptive statistics (number [n], mean, SD, median, minimum, and maximum) will 
be provided. For categorical variables, patient counts and percentages will be provided. 
Categories for missing data will be presented if necessary. 
Treatment groups will be compared for all continuous variables, using an analysis of variance 
(ANOVA) with treatment group as a factor. The categorical variables of patient sex and race will 
be summarized using descriptive statistics for each variable category. Missing categories will be

Wearable sensor substudy exploratory endpoints are the following: 
• change in total sleep time, sleep onset latency, wake after sleep onset, and sleep 
efficiency on days with and without CH attacks 
• the change in the total time of sedentary, light, moderate, and vigorous activity before 
(6-hour period), during, and after (6-hour period) CH attack relative to days free of 
attacks

9.5.4. 
Planned Method of Analysis 
The full analysis set (see Section 9.2.3) will be used for all efficacy analyses. Summaries will be 
presented by treatment group. 
9.5.4.1. 
Primary Efficacy Analysis 
The primary efficacy endpoint, the mean change from baseline (run-in period) in the monthly 
average number of CH attacks during the 12-week period after administration of the first dose of 
the IMP, will be analyzed using an analysis of covariance (ANCOVA). The model will include 
treatment, baseline number of CH attacks, baseline preventive medication use (yes or no), 
gender, and region (US or other).

9.5.4.2. 
Sensitivity Analysis 
Sensitivity analysis may be conducted to explore the impact of missing data in the primary 
efficacy analysis. Details will be provided in the statistical analysis plan. 
9.5.4.3. 
Secondary and Exploratory Efficacy Analysis 
The continuous endpoints will be analyzed using an ANCOVA or a mixed model for repeated 
measures. For the proportion of responders, defined as 50% or more reduction from baseline in 
the monthly average number of CH attacks, data will be analyzed using a 
Cochran-Mantel-Haenszel test stratified by baseline preventive medication use (yes/no). 
9.6. 
Multiple Comparisons and Multiplicity 
Hochberg’s step-up method will be implemented to test primary and secondary endpoints while 
controlling the overall type 1 error rate at 0.05. The treatment comparisons will be for the 
fremanezumab 900-mg iv loading dose group versus placebo [H01] and the fremanezumab 
675-mg sc loading dose group versus placebo [H02]. According to Hochberg step-up method, the 
rules of multiple comparisons for 2 null hypotheses for the primary endpoint are as follows: 
1. If the resulting 2-sided p-values from both comparisons are ≤0.05 (reject both null 
hypotheses), then the next comparison of interest will be interpreted inferentially at the 
alpha level of 0.05 and statistical significance will be claimed for both active dose 
groups. Testing of secondary efficacy measures will be continued. 
2. If the resulting 2-sided p-value from 1 of comparisons is >0.05 (fail to reject the null 
hypothesis) and the other resulting 2-sided p-value is ≤0.025 (α/2=0.025; reject the null 
hypothesis), the result from the comparison with p-value ≤0.025 will be interpreted 
inferentially at the alpha level of 0.05, and statistical significance will be claimed for this 
active dose group. No other comparison(s) will be interpreted inferentially. 
3. If the resulting 2-sided p-value from both comparisons are >0.05 (fail to reject both null 
hypotheses), no statistical significant will be claimed and no comparisons will be 
interpreted inferentially. 
If the resulting 2-sided p-values from both comparisons for the primary endpoint are ≤0.05 
(reject both hypotheses; case 1 as described above), testing of secondary efficacy measures will 
proceed at an error rate of 0.05 in the sequential manner as specified in Section 2.1. The same 
testing rules as described above will be followed. This process will continue either until all 
comparisons of interest for secondary endpoints are interpreted inferentially or until the point at 
which the resulting 2-sided p-value for a comparison of interest is >0.05. At the point where a 
2-sided p-value is >0.05, the testing process stops. No further comparisons will be interpreted 
inferentially. 
9.7. 
Safety Analysis 
Safety analyses will be performed on the safety analysis set (Section 9.2.2). Safety assessments 
and time points are provided in Table 2. 
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 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
87 
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 test IMP (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. 
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 IMP. 
Changes in laboratory, ECG, 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. 
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. 
9.8. 
Tolerability Analysis 
Tolerability was not specifically defined. 
9.9. 
Pharmacokinetics Analysis 
Pharmacokinetics plasma concentration results (fremanezumab) will be tabulated descriptively at 
each planned sampling time point by treatment group. 
In addition, the most appropriate population pharmacokinetics model will be developed, and 
covariates that may affect it will be tested for inclusion in the model. This analysis will be 
reported separately. 
9.10. 
Pharmacokinetic/Pharmacodynamics Analysis 
The pharmacokinetics/pharmacodynamics relationship may be estimated by compartmental 
techniques. The pharmacokinetics parameters will be based on fremanezumab measurements. 
The pharmacodynamics parameters will be the efficacy response(s).  
The pharmacokinetics/pharmacodynamics relationship may be estimated using the most 
appropriate model after comparing different candidate models for their quality of fit. Covariates 
that may affect the pharmacokinetics/pharmacodynamics relationship will be tested for inclusion 
in the model. If performed, this analysis will be reported separately.

Pharmacogenomic Analysis 
Pharmacogenomic analysis results will be summarized for each gene tested. An attempt will be 
made to correlate clinical observations (pharmacokinetics, safety, efficacy, or other effects) with 
the genotypes observed. Additional pharmacogenomic analysis may be conducted at a later time 
and will be reported in a separate addendum report. 
9.12. 
Biomarker Analysis 
Biomarker analysis will include logistic regression, receiver operating characteristic curves, and 
summary statistics. Results will be reported separately. Measurements will be made using 
validated assays. 
9.13. 
Immunogenicity Analysis 
A summary of immunogenicity results will be provided, and the incidence of immunogenicity 
will be calculated. The impact of immunogenicity on the pharmacokinetics profile, IMP efficacy, 
and clinical safety will be evaluated. This ADA impact analysis will be reported separately. 
9.14. 
Ancillary Study Analysis 
Analysis will include summary statistics and multimodal algorithms to monitor physiological 
activity, sleep/wake activity, and treatment responses. Results will be reported separately. 
9.15. 
Planned Interim Analysis 
An interim analysis for futility will be performed once 50% of patients (the first 150 patients) 
have completed 12-week assessments during the double-blind study period or have withdrawn 
from the study early. An independent statistician from a third party will perform evaluations.  
9.16. 
Reporting Deviations from the Statistical Plan 
Deviations from the statistical plan, along with the reasons for the deviations, will be described 
in protocol amendments, the statistical analysis plan, the clinical study report, or any 
combination of these, as appropriate, and in accordance with applicable national, local, and 
regional requirements and regulations.

SUMMARY OF CHANGES TO THE PROTOCOL 
16.1. 
Amendment 02 Dated 01 May 2017 
The primary reason for this amendment is to provide clarification based on feedback from 
participating investigators and regulatory agencies. This amendment is considered to be 
substantial (ie, requires approval by competent authorities, IEC, and/or IRB) by the sponsor’s 
Authorized Representative.  
These changes are unlikely to affect the safety or rights (physical or mental integrity) of the 
patients or the scientific value of the clinical study.  
Table 2 (Study Procedures and Assessments) has been revised to reflect changes described 
below.

It is relevant to note that due to the higher exposure observed 
in the recent clinical Study TV48125-PK-10078 (Japanese 
bridging study), a re-evaluation of the safety margins was 
performed. An internal investigation indicates that the original 
assay underestimated fremanezumab measured plasma 
concentrations. Comparison of the exposure parameters of 
maximum observed concentration (Cmax) and area under the 
plasma concentration-time curve from time 0 to infinity

exposure parameters from Study TV48125-PK-10078, which 
were analyzed using the newer validated assay for the 225-mg 
and 900-mg sc dose levels, indicates an apparent exposure 
difference between 2.9- and 3.5-fold in Study 
TV48125-PK-10078 relative to Study LBR-101-011. Thus, the 
most conservative factorvalue of 3.5 was used to recalculate 
the safety margins, meaning that LBR-101-011 exposure was 
assumed to be 3.5-fold higher than originally reported, and as 
such, safety margins decreased by 3.5-fold.

16.2. 
Amendment 01 Dated 30 November 2016 
The primary reason for this amendment is to update the primary endpoint based on feedback 
from regulatory agencies and the sample size for this study based on the new primary endpoint. 
This amendment is considered to be substantial (ie, requires approval by competent authorities, 
IEC, and/or IRB) by the sponsor’s Authorized Representative. This amendment also incorporates 
changes detailed in the letter of clarification 01 (Section 16.4), letter of clarification 02 
(Section 16.3), and letter of clarification 03 (Section 16.2) and other nonsubstantial changes. 
These changes are unlikely to affect the safety or rights (physical or mental integrity) of the 
patients in this clinical study or the scientific value of the clinical study. 
Table 2 (Study Procedures and Assessments) has been revised to reflect changes described 
below.

APPENDIX C. QUALITY CONTROL AND QUALITY ASSURANCE 
Protocol Amendments and Protocol Deviations 
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. 
Protocol Deviations 
Any deviation from the protocol that affects, to a significant degree, (a) the safety, physical, or 
mental integrity of the patients in the study and/or (b) the scientific value of the study will be 
considered an important protocol deviation. Important protocol deviations may include non-
adherence 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 
IMP administration; use of prohibited medications. All important protocol deviations will be 
reported to the responsible IEC/IRB, as required. 
When an important protocol deviation 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. A noncompliant patient may continue 
taking the study treatment only if this does not jeopardize the patient’s safety. The sponsor will 
assess each protocol deviation and decide whether any of these noncompliances should be 
reported to the Regulatory Authority as a serious breach of GCP and the protocol. 
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 deviation. A deviation from the eligibility criteria will always result in 
study drug discontinuation in case the patient has not been dosed. In case a patient who was 
wrongly randomized has already started taking the study drug, a risk/benefit evaluation has to 
take place and a strong clinical justification must be provided in case the patient is not withdrawn 
from the study drug. If such patient has already completed the study or has withdrawn early, no 
action will be taken but the deviation will be recorded. 
Information to Study Personnel 
The investigator is responsible for giving information about the study to all personnel 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 personnel become involved). The investigator must 
ensure that all study personnel are qualified by education, experience, and training to perform 
their specific task. These study personnel members must be listed on the investigational center 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
149 
authorization form, which includes a clear description of each personnel 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 personnel, including the 
investigator, and for ensuring they comply with the protocol. 
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 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 monitors will contact the investigator and visit the investigational center according to 
the monitoring plan. The study monitor will be permitted to review and verify the various 
records (CRFs and other pertinent source data records, including specific electronic source 
document relating to the study) to verify adherence to the protocol and to ensure the 
completeness, consistency, and accuracy of the data being recorded. 
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 personnel must agree to cooperate with the study monitor to resolve any problems, 
errors, or possible misunderstandings concerning the findings detected during the course of these 
monitoring visits or provided in follow-up written communication. 
Audit and Inspection 
The sponsor may audit the investigational center to evaluate study conduct and compliance with 
protocols, SOPs, GCP guidelines, and applicable regulatory requirements. The sponsor’s Global 
Clinical Quality Assurance, independent of Global Specialty Development, is responsible for 
determining the need for (and timing of) an investigational center audit. 
The investigator must accept that competent authorities and sponsor representatives may conduct 
inspections and audits to verify compliance with GCP guidelines.

Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
150 
APPENDIX D. ETHICS 
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 oral information about the study will be provided in a language as 
nontechnical as practical to be 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 documents. 
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. The patient’s willingness to participate in the study will be 
documented in the informed 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 informed 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 participation in the study and free to 
withdraw from the study at any time without prejudice to future treatment. 
Competent Authorities and Independent Ethics Committees/Institutional Review Boards 
Before this study starts, the protocol will be submitted to the national competent authority and to 
the respective IEC/IRB for review. As required, the study will not start at a given investigational 
center before the IEC/IRB and competent authority (as applicable) for the investigational center 
give written approval or a favorable opinion. 
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 number. 
Personal medical information may be reviewed for the purpose of patient safety or for verifying 
data in the source and the CRF. This review may be conducted by the study monitor, properly 
authorized persons on behalf of the sponsor, Global Quality Assurance (GCA), or competent 
authorities. Personal medical information will always be treated as confidential. 
Registration of the Clinical Study 
In compliance with national and local regulations and in accordance with Teva standard 
procedures, this clinical study will be registered on trials registry websites.

APPENDIX E. 
WOMEN OF CHILDBEARING POTENTIAL AND BIRTH 
CONTROL METHODS 
Assessment of likelihood of possible interaction between investigational medicinal product 
(IMP) or concomitant medications and hormonal contraception should be conducted. Hormonal 
contraception may be susceptible to interaction with the IMP, which may reduce the efficacy of 
the contraception method. 
Drug interaction studies have not been conducted with fremanezumab. Like other therapeutic 
antibodies, fremanezumab is expected to be primarily metabolized via proteolytic catabolism. 
Therefore, interaction with and impact on drug metabolizing enzymes (eg, CYP isoforms) is 
considered unlikely in humans. 
In addition, fremanezumab is not expected to indirectly influence the CYP enzymes. In general, 
protein products that are cytokine modulators have been reported to affect the metabolism or 
disposition of co-administered medication by altering CYP enzymes/transporters (FDA 2012). 
Fremanezumab is an IgG2 isotype that is directed against a non-immunologic and soluble (not 
cell bound) target. Thus, the risk of cytokine release is considered to be low in the clinical 
setting. Furthermore, fremanezumab was tested for stimulation of pro-inflammatory cytokine 
release in human whole blood (Study 111320). Fremanezumab did not elicit significant cytokine 
release (TNF-α, IL-6, INF-γ, or IL-1β) in any donor including at concentrations up to 
100 μg/mL. As such, there is no reason to suspect that fremanezumab may influence CYP 
activity. 
Women of non-childbearing potential are defined as: 
• Surgically (hysterectomy, bilateral oophorectomy, or bilateral salpingectomy) or 
congenitally sterile 
• One year postmenopausal (stable amenorrhea for 12 months without alternative 
medical cause plus high follicle-stimulating hormone (FSH) in the postmenopausal 
range) in women not using hormonal contraception or hormonal replacement therapy 
• Women in stable post-menopause, but are taking hormone replacement therapy for 
the treatment of menopausal symptoms, may be considered eligible for the study even 
with the lower serum FSH. They do not need to use other contraception. 
Highly effective birth control methods: 
 
Highly effective birth control methods are methods that can achieve a failure rate of less than 1% 
per year when used consistently and correctly are considered. Such methods include the 
following: 
• Combined estrogen and progestogen hormonal contraception (oral, intravaginal, or 
transdermal) associated with inhibition of ovulation; these should be initiated at least 
7 days  before dosing of IMP. 
• Progestogen-only hormonal contraception (oral, injectable, or implantable) associated 
with inhibition of ovulation; these should be initiated at least 7 days before dosing of 
IMP. 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
152 
• Intrauterine device (IUD) and intrauterine hormone-releasing system (IUS) need to be 
in place at least 2 months before screening. 
• Bilateral tubal occlusion  
• Vasectomized partner provided that he is the sole sexual partner and has received 
medical assessment of the surgical process. 
• Sexual abstinence is only considered a highly effective method if defined as 
refraining from heterosexual intercourse in the defined period. The reliability of 
sexual abstinence needs to be evaluated in relation to the duration of the clinical study 
and the preferred and usual lifestyle of the patient. 
• Periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods), 
declaration of abstinence for the duration of a study, and withdrawal are not 
acceptable  methods of contraception (according to Medicines and Healthcare 
Products Regulatory Agency). 
Acceptable birth control methods: 
Acceptable birth control methods that result in a failure rate of more than 1% per year include 
progestogen-only oral hormonal contraception for which the inhibition of ovulation is not the 
primary mode of action; male or female condom with or without spermicide; cap; diaphragm; or 
sponge with spermicide. The combinations of male condom with cap, diaphragm, or sponge with 
spermicide (double-barrier methods) are also considered acceptable but not highly effective 
methods of birth control. 
Unacceptable birth control methods: 
Periodic abstinence (calendar, symptothermal, or post-ovulation methods), withdrawal (coitus 
interruptus), spermicides only, and lactational amenorrhea method are not acceptable methods of 
contraception. Female condom and male condom should not be used together. 
Male contraception: 
Male subjects must always use a condom. 
Vasectomy: 
Use of contraceptive methods applies also to vasectomized men. 
Pregnant female partners of male study participants: 
Male study participants must use condoms during intercourse if their female partners are

APPENDIX F. LOST TO FOLLOW-UP 
A patient will be considered lost to follow-up if he/she repeatedly fails to return for scheduled 
visits and 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). 
The following actions must be taken if a patient fails to return to the investigational center for a 
required study visit: 
• The investigational center must attempt to contact the patient and reschedule the 
missed visit as soon as possible and counsel the patient on the importance of 
maintaining the assigned visit schedule and ascertain whether or not the patient 
wishes to and/or should continue in the study. 
• In cases in which the patient is deemed lost to follow-up, the investigator or designee 
must make every effort to regain contact with the patient (where possible, 3 telephone 
calls and, if necessary, a certified letter to the patient’s last known mailing address or 
local equivalent methods). These contact attempts should be documented in the 
patient’s medical record. 
• Should the patient continue to be unreachable, he/she will be considered to have 
withdrawn from the study with a primary reason of ‘lost to follow-up’.

APPENDIX G. HANDLING, LABELING, STORAGE, AND 
ACCOUNTABILITY FOR INVESTIGATIONAL 
MEDICINAL PRODUCT(S) 
Preparation of Investigational Medicinal Products 
Fremanezumab or placebo will be provided in prefilled syringes contained in uniquely numbered 
kits and stored accordingly (see above). At the time of each study visit, the IRT will be queried, 
and investigational site personnel will retrieve the appropriately numbered kit(s). Kit numbers 
will be entered into the CRF. 
Preparation instructions for iv infusions: Investigational medicinal product (IMP) syringes 
should be allowed to equilibrate at room temperature for 45 to 60 minutes before administration 
into the iv bag. The contents of 4 prefilled syringes, each containing fremanezumab (225 mg/1.5 
mL) or 1.5 mL of placebo, will be added to 500 mL of normal saline solution. The iv infusion 
will be administered over approximately 1 hour. 
Preparation instructions for sc injections: IMP should be allowed to equilibrate at room 
temperature for 45 to 60 minutes before sc administration. A 1.5 mL volume from each syringe 
in each visit kit(s) must be injected sc for dosing to be considered complete. Refer to 
Appendix U for additional details regarding recommended sc injection sites. 
Storage and Security 
The investigator or designee must confirm appropriate temperature conditions have been 
maintained for all IMPs received and any discrepancies are reported and resolved before use of 
the IMPs. 
The test IMP (fremanezumab) and placebo IMP must be stored refrigerated at 2°C to 8°C (36°F 
to 46°F), protected from light; the investigational site should have a process for monitoring the 
drug storage temperature. 
Diversion is considered to have occurred when the legal supply chain of prescription analgesic 
medicinal products is broken, and medicinal products are transferred from a licit to an illicit 
channel of distribution or use. 
Labeling 
Supplies of IMPs will be labeled in accordance with the current International Council for 
Harmonisation (ICH) guidelines on Good Clinical Practice (GCP) and Good Manufacturing 
Practice and will include any locally required statements. If necessary, labels will be translated 
into the local language. 
Accountability 
Each IMP shipment will include a packing slip listing the contents of the shipment, return 
instructions, and any applicable forms. 
The investigator is responsible for ensuring that deliveries of IMPs and other study materials 
from the sponsor are correctly received, recorded, handled, and stored safely and properly in 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
155 
accordance with the CFR or national and local regulations, and used in accordance with this 
protocol. 
Only patients enrolled in the study may receive IMPs and only authorized staff at the 
investigational center may supply or administer IMPs. All IMPs must be stored in a secure, 
environmentally controlled, and monitored (manual or automated) area in accordance with the 
labeled storage conditions or appropriate instructions with access limited to the investigator and 
authorized staff at the investigational center. 
The investigator, institution, or the head of the medical institution (where applicable) is 
responsible for IMP accountability, reconciliation, and record maintenance (ie, receipt, 
reconciliation, and final disposition records). 
A record of IMP accountability (ie, IMP and other study 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. Empty and partially used prefilled syringes should 
be destroyed, and the investigational site should provide a certificate of destruction. If the 
investigational site does not have the capability to destroy the used and partially used prefilled 
syringes, the prefilled syringes should be sent back to the sponsor. Unused prefilled syringes of 
IMP will be returned to the sponsor or designee.

APPENDIX J. GUIDANCE ON SAFETY MONITORING 
Guidance on Monitoring Patients with Elevated Liver Function Tests 
Liver enzymes (ALT, AST, GGT, and ALP) as well as total, direct, and indirect bilirubin will be 
measured 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.2 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, direct, or indirect 
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 IMP discontinuation in cases of elevation of either ALT or AST 
≥3 × ULN. (Note: In cases of elevation of ALT or AST ≥8 × the ULN, no confirmation is 
required prior to IMP discontinuation, but the assessments below should be performed.) The 
following procedures should be followed: 
• The 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 cell [CBC] count 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, bilirubin [total, direct, and indirect], 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 
                                                 
2 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.

Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
159 
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 immunoglobulins M and G), B (core antibody 
total, core immunoglobulin M, 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 <5 × the 
ULN 
In addition to the above procedures required for any elevation to levels >3 × the ULN: 
• Alanine aminotransferase, AST, GGT, ALP, total bilirubin, direct bilirubin, indirect 
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 bilirubin, direct bilirubin, 
indirect bilirubin should be sent to the central laboratory at least once a month. 
ALT or AST ≥5 × but <8 × the ULN 
In addition to the above procedures required for any elevation to levels >3 × the ULN: 
• Alanine aminotransferase, AST, GGT, ALP, total bilirubin, direct bilirubin, indirect 
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. 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
160 
ALT or AST ≥8 × the ULN 
In addition to the above procedures required for any elevation to levels >3 × the ULN: 
• The IMP should be discontinued immediately, and the early withdrawal visit should 
be performed. 
• For follow-up guidance, please see below section “Follow-Up of Liver Enzymes after 
Stopping Rules Are Met.” 
Stopping Rules 
In the following circumstances, the IMP will be discontinued immediately: 
• any increase in ALT or AST to ≥3 × the ULN, combined with INR >1.5 × the ULN 
or total bilirubin >2 × the ULN 
• any increase in ALT or AST to ≥3 × the ULN, which is accompanied by symptoms 
clearly associated with impaired liver function (eg, vomiting, nausea, fever, rash, and 
eosinophilia) and not deemed related to other diseases (eg, vomiting or nausea 
triggered by cluster headache) 
• any increase in ALT or AST to levels ≥5 but <8 × the ULN, which is persistent for 
≥2 weeks of repeated measurements 
• any increase in ALT or AST to levels ≥8 × the ULN 
• in any case where monitoring of liver enzymes cannot be performed according to the 
protocol guidance 
Follow-Up of Liver Enzymes After Stopping Rules Are Met 
• A patient who meets the above criteria for discontinuation of the IMP should be 
invited to the investigational site to return the IMP. 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.

APPENDIX K. CLINICAL CRITERIA FOR DIAGNOSING 
ANAPHYLAXIS 
As detailed by Sampson et al 2006, anaphylaxis is broadly defined as, “a serious allergic reaction 
that is rapid in onset and may cause death.” Diagnostic criteria defined by the National Institute 
of Allergy and Infectious Disease/Food Allergy and Anaphylaxis Network during the second 
symposium on the definition and management of anaphylaxis, modified from Sampson et al 
2006, are as follows: 
Anaphylaxis is highly likely when any 1 of the following 3 criteria is fulfilled: 
1. Acute onset of an illness (minutes to several hours) with involvement of the skin, 
mucosal tissue, or both (eg, generalized hives, pruritus or flushing, swollen lips-tongue-
uvula) and at least 1 of the following: 
a. respiratory compromise (eg, dyspnea, wheeze-bronchospasm, stridor, reduced peak 
expiratory flow [PEF], hypoxemia) 
b. reduced blood pressure or associated symptoms of end-organ dysfunction 
(eg, hypotonia [collapse], syncope, incontinence) 
2. Two or more of the following that occur rapidly after exposure to a likely allergen for 
that patient (minutes to several hours): 
a. involvement of the skin-mucosal tissue (eg, generalized hives, itch-flush, swollen 
lips-tongue-uvula) 
b. respiratory compromise (eg, dyspnea, wheeze-bronchospasm, stridor, reduced PEF, 
hypoxemia) 
c. reduced blood pressure or associated symptoms (eg, hypotonia [collapse], syncope, 
incontinence) 
d. persistent gastrointestinal symptoms (eg, crampy abdominal pain, vomiting) 
3. Reduced blood pressure after exposure to known allergen for that patient (minutes to 
several hours): 
a. adults: systolic blood pressure of <90 mm Hg or >30% decrease from that person’s 
baseline 
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. 
As a precaution, each investigational site should have a resuscitation cart nearby.

APPENDIX N. PHARMACOKINETICS SAMPLES 
Specimen Sampling and Handling 
For plasma collection, samples will be collected in anticoagulant tubes, inverted slowly 
6 to 8 times to mix the contents, and placed on water/ice (approximately 4°C). Blood samples 
will be centrifuged (1500 g, approximately 10 minutes, at 2 to 8°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 in 2 labeled 2 mL-polypropylene tubes (Sets A and B). 
Labels for samples should include study number, patient randomization number, nominal 
collection time (Visit number), Set A or B, and indication that they are pharmacokinetic samples. 
Samples will be stored at a temperature of –70ºC to -20°C (inclusive) in an upright position until 
they are shipped to the central laboratory. 
Shipment and Analysis of Samples 
Plasma samples for all patients will be shipped from the investigational center to the central 
laboratory, where they will be stored until shipped to the sponsor or designee for analysis. 
Samples will be stored in an upright position at –70ºC until assayed. The central laboratory will 
be notified before the shipment of the samples and will be sent the shipping information when 
the samples are shipped. An electronic file containing sample demographics will be emailed to 
the bioanalytical laboratory and the sponsor’s representatives from bioanalytical departments for 
each shipment. 
Set A samples will be transported frozen, with a temperature data logger and with dry ice 
sufficient for 4 days, on a monthly basis to the central laboratory. Central laboratory will ship the 
Set A samples on a monthly basis to the bioanalytical laboratory with dry ice sufficient for 4 
days and with a temperature data logger.  
Set B samples will be sent to the same laboratory as that for Set A. Instructions as to the 
disposition of the Set B samples will be provided by the sponsor. Sample shipments should be 
sent no later in the week than Wednesday morning for next‑day delivery. Samples are not to 
arrive on the weekend. 
Samples will be analyzed using an appropriate validated method. Timing of the initiation of 
sample analysis will be determined by the sponsor’s representatives of bioanalytical departments 
responsible for the bioanalysis while keeping the study blinding, if any, intact.

APPENDIX O. IMMUNOGENICITY SAMPLES 
Blood Sampling and Handling 
For serum collection, samples will be collected in Vacutainer tubes containing no anticoagulant, 
and allowed to set at room temperature for between 1 and 1.5 hours to allow for serum separation 
to occur. Samples will then be centrifuged (1500 g, approximately 10 minutes, at 2 to 8°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 in 2 labeled 
2 mL-polypropylene tubes (Sets A and B). 
Label of samples should include study number, patient randomization number, nominal 
collection time (Visit number), Set A or B, and indication that they are ADA samples. Serum 
samples will be stored at a temperature of –70ºC to -20°C (inclusive) in an upright position until 
they are shipped to the central laboratory. 
Shipment and Analysis of Samples 
Serum samples for all patients will be shipped from the investigational center to the central 
laboratory, where they will be stored until shipped to the sponsor or designee for analysis. 
Samples will be stored in an upright position at –70ºC until analysis. The central laboratory will 
be notified before the shipment of the samples and will be sent the shipping information when 
the samples are shipped. An electronic file containing sample demographics will be emailed to 
the central laboratory for each shipment. The same will be copied to the sponsor’s 
representatives of bioanalytical departments responsible for the bioanalysis. 
Set A samples will be transported frozen, with a temperature data logger and with dry ice 
sufficient for 4 days, on a monthly basis to the central laboratory. Central laboratory will ship the 
set A samples on a monthly basis to the bioanalytical laboratory with dry ice sufficient for 4 days 
and with a temperature data logger.  
Set B samples will be sent to the same laboratory as that for Set A. Instructions as to the 
disposition of the Set B samples will be provided by the sponsor. Sample shipments should be 
sent no later in the week than Wednesday morning for next‑day delivery. Samples are not to 
arrive on the weekend. 
Samples will be analyzed using an appropriate validated method. Timing of the initiation of

APPENDIX P. EXPLORATORY BIOMARKERS SAMPLES 
Blood samples (8.5 mL serum, 6 mL plasma and 2.5 mL for RNA [PAXgene]) will be collected 
via venipuncture or indwelling catheter at the time points detailed in Table 2 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 (or a later visit) for 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 code number. Following DNA 
extraction from the pharmacogenomic sample, the sample will be labeled with a new code 
(ie, double coding), so that genetic data will not be recorded with a patient number.  
Samples will be stored for a period of up to 15 years from the last patient’s last visit in the main 
study and then destroyed. 
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 the 
laboratory manual. An electronic file containing sample demographics will be emailed 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.

APPENDIX Q. PHARMACOGENOMIC ASSESSMENTS 
Blood samples (6 mL) for pharmacogenomic assessments will be collected from all patients in 
the study who signed the ICF for the pharmacogenomic assessments at the time point detailed in 
Table 2. Pharmacogenomic assessment potentially includes the association of DNA variations in 
specific genes of interest with clinical responses to test IMP (eg, efficacy, pharmacokinetics, 
tolerability, and safety features or disease susceptibility and severity features). The current list of 
genes with polymorphisms associated with either calcitonin gene-related peptide target 
engagement or cluster headache mechanism of action includes CALCA, CALCB, CALCRL, 
CRCP, RAMP, PRDM16, AJAP1, TSPAN2, MEF2D, TRPM8, TGFBR2, PHACTR1, FHL5,

APPENDIX R. PRODUCT COMPLAINTS 
Clinical Product Complaints 
A clinical product complaint is defined as a problem or potential problem with the physical 
quality or characteristics of clinical IMP supplies or clinical device supplies used in a clinical 
research study sponsored by Teva. Examples of a product complaint include but are not limited 
to: 
• suspected contamination 
• questionable stability (eg, color change, flaking, crumbling, etc) 
• defective components 
• missing or extra units (eg, primary container is received at the investigational center 
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 
• 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 an IMP, all relevant samples (eg, the remainder of the patient’s IMP supply) should be 
sent back to the sponsor for investigative testing whenever possible. 
1. Product Complaint Information Needed from the Investigational Center 
In the event that the product complaint form cannot be completed, the investigator will provide 
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 
• product name and strength for open-label studies 
• patient number, bottle, and kit numbers (if applicable) for double-blind or open-label 
studies 
• product available for return Yes/No 
• product was taken or used according to protocol Yes/No 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
169 
• description or nature of complaint 
• associated serious adverse event Yes/No 
• clinical supplies unblinded (for blinded studies) Yes/No 
• date and name of person receiving the complaint 
Note: Reporting a product complaint must not be delayed even if not all the required information 
can be obtained immediately. Known information must be reported immediately. The sponsor 
will collaborate with the investigator to obtain any outstanding information. 
2. Handling of Investigational Medicinal Product(s) at the Investigational Center(s) 
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 IMP. 
If it is determined that the investigational center must return all IMP, 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 
problem existing beyond the scope of the complaint may be a reason to unblind the clinical 
supplies for an affected patient. 
3. Adverse Events or Serious Adverse Events Associated with a Product Complaint 
If there is an adverse event or serious adverse event due to product complaint, the protocol 
should be followed for recording and reporting (Section 7.1.2 and Section 7.1.5, respectively). 
4. Documenting a Product Complaint 
The investigator will record in the source documentation a description of the product complaint, 
and 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. 
Medical device incidents, including those resulting from malfunctions of the device, must be 
detected, documented, and reported by the investigator throughout the study.

APPENDIX S. DATA MANAGEMENT AND RECORD KEEPING 
Direct Access to Source Data and Documents 
All patient data must have supportive original source documentation in the medical records, or 
equivalent, before they are transcribed to the CRF. Data may not be recorded directly on the CRF 
and considered as source data unless the sponsor provides written instructions specifying which 
data are permitted to be recorded directly to the CRF. 
If data are processed from other institutions or by other means (eg, clinical laboratory, central 
image center, or electronic diary data) the results will be sent to the investigational center, where 
they will be retained but not transcribed to the CRF, unless otherwise noted in the protocol. 
These data may also be sent electronically to the sponsor (or organization performing data 
management). 
The medical experts, study monitors, auditors, IEC/IRB, and inspectors from competent 
authority (or their agents) will be given direct access to source data and documents (eg, medical 
charts/records, laboratory test results, printouts, videotapes) for source data verification, provided 
that patient confidentiality is maintained in accordance with national and local requirements. 
The investigator must maintain the original records (ie, source documents) of each patient’s data 
at all times. The investigator must maintain a confidential patient identification list that allows 
the unambiguous identification of each patient. 
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 CDMS that meets the technical requirements described in 
21CFR Part 11 (USA) and documents of other concerned competent authorities. Before using the 
CDMS, it will be fully validated and 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. 
If data are processed from other sources (eg, central laboratory, bioanalytical laboratory, central 
image center, electronic diary data, ePRO tablet), these data will be sent to the investigational 
center, where they will be retained but not transcribed to the CRF, unless otherwise noted in the 
protocol. These data may also be sent electronically to the sponsor (or organization performing 
data management). All patient data must have supportive original source documentation in the 
medical records, or equivalent, before they are transcribed to the CRF. Data may not be recorded 
directly on the CRF and considered as source data unless the sponsor provides written 
instructions specifying which data are permitted to be recorded directly to the CRF. 
For patients who enter a study but do not meet entry criteria, at a minimum, data for screening 
failure reason, demography, and adverse events from the time of informed consent will be 
entered in the CRF.

Data Quality Control 
Data Management is responsible for the accuracy, quality, completeness, and internal 
consistency of the data from this study. 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 contract organization, 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. 
Data will be verified by the study monitor using the data source, and reviewed by Data 
Management using both automated logical checks and manual review. Data identified as 
erroneous, or data that are missing, will be referred to the investigational center for resolution 
through data queries. 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 and any discrepancies will be queried. 
Applicable terms will be coded according to the coding conventions for this study. 
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. 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. 
Archiving of Case Report Forms and Source Documents 
Sponsor Responsibilities 
The original CRFs will be archived by the sponsor. Investigational center-specific CRFs will be 
provided to the respective investigational centers for archiving. 
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 national and local laws, including, but not limited to: 
• full case histories 
• signed informed consent forms 
• patient identification lists 
• case report forms for each patient on a per-visit basis 
• data from other sources (eg, central laboratory, bioanalytical laboratory, central image 
center, electronic diary) 
• safety reports 
• financial disclosure reports/forms 
• reports of receipt, use, and disposition of the IMPs 
• copies of all correspondence with sponsor, the IEC/IRB, and any competent authority 

 
Placebo-Controlled Study–Chronic Cluster Headache 
Clinical Study Protocol with Amendment 02 
Study TV48125-CNS-30057 
172 
The investigator will retain all records related to the study and any additional records required, as 
indicated by the protocol and according to applicable laws and regulations, until the CRO or 
sponsor notifies the institution in writing that records may be destroyed. If, after 25 years from 
study completion, or earlier in the case of the investigational 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 60 days before any planned 
disposition of study records. After 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.
