General Design:
This is a 68-week extension study to evaluate the long-term safety and efficacy of fremanezumab
in adult patients with CH. During the course of any CH attack, patients will be allowed to use 
acute medications to treat acute headaches, as needed (PRN).
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 TV 48125-CNS-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. 
Prior to 15 June 2018, up to 360 eligible patients with ECH and CCH rolling over from the 
pivotal studies (Studies TV48125-CNS-30056 and TV48125-CNS-30057, respectively) will 
receive fremanezumab during this study as summarized in Table 1. After 15 June 2018, only 
patients who participated in the ECH study (Study TV48125-CNS-30056) will be enrolled in this 
study for active treatment. At the time of unblinding the treatment code in 
Study TV48125-CNS-30057 (planned for Q4 2018), those CCH patients who were receiving 
placebo in Study TV48125-CNS-30057 (ie, never received any study drug) will not be required 
to complete additional safety follow-up visits, and will be discharged from the study.

a In order to maintain blinding throughout the study, the number of sc injections at each visit will be the same for all 
patients rolling over from Study TV48125-CNS-30056, regardless of their assigned treatment group. Thus, 
patients will receive 3 sc injections of test IMP (1.5 mL-injections each containing fremanezumab at a 
concentration of 150 mg/mL) or 1 injection of test IMP (1.5-mL injection containing fremanezumab at a 
concentration of 150 mg/mL) and 2 sc injections of placebo IMP (1.5-mL injections) at visits 1, 4, 7, and 10, and a 
single sc injection of test IMP or placebo IMP at visits 2, 3, 5, 6, 8, and 9.
b In order to maintain blinding throughout the study, the number of sc injections at each visit will be the same for all 
patients rolling over from Study TV48125-CNS-30057, regardless of their assigned treatment group. Thus, 
patients will receive 3 sc injections of either test IMP (1.5-mL injections each containing fremanezumab at a 
concentration of 150 mg/mL) or 1 sc injection of test IMP (1.5-mL injection containing fremanezumab at a 
concentration of 150 mg/mL) and 2 sc injections of placebo IMP (1.5-mL injections) at visit 1, and patients will 
receive a single sc injection of test IMP (1.5-mL injection containing fremanezumab at a concentration of 
150 mg/mL) at all other visits.
c Fremanezumab at 900 mg iv at visit 2 (week 0) of the pivotal study and fremanezumab at 225 mg sc at visits 3 and 
4 (weeks 4 and 8, respectively) of the pivotal study.

Patients with a diagnosis of ECH who experience CH remission, defined as no CH attacks for 
12 successive weeks at any time after starting IMP (ie, administration of the first dose of IMP in 

Uncontrolled Study–Cluster Headache

the pivotal study), will be offered the possibility to stop treatment and continue to attend the 
subsequent scheduled visits. If treatment is stopped and CH attacks resume within 12 weeks after 
stopping treatment, patients will restart treatment at their previous dose regimen through 
week 36. If treatment is stopped and CH attacks resume after more than 12 weeks after stopping 
treatment, patients will restart fremanezumab treatment at 675 mg subcutaneous (sc) quarterly 
through week 36.
Patients with a diagnosis of CCH who experience CH remission, defined as no CH attacks for 
24 successive weeks at any time after starting IMP (ie, administration of the first dose of IMP in 
the pivotal study), will be offered the possibility to stop treatment and continue to attend the 
subsequent scheduled visits. If treatment is stopped and CH attacks resume within 12 weeks after 
stopping treatment, patients will restart fremanezumab treatment at 225 mg sc monthly through 
week 36. If treatment is stopped and CH attacks resume after more than 12 weeks after stopping 
treatment, patients will restart fremanezumab treatment with a 675-mg sc loading dose followed 
by 225-mg sc monthly through week 36. After 15 June 2018, only patients who participated in 
the ECH study (Study TV48125-CNS-30056) will be enrolled for active treatment. All CCH 
patients included in this study have been asked to discontinue treatment and are encouraged to 
continue in the ADA and safety follow-up portion of this study.
All patients will return to the study center approximately every 4 weeks after administration of 
the first dose of the IMP (visit 1 [week 0]) through the end-of-treatment (EOT) visit (visit 11 
[week 40]), which will occur approximately 4 weeks after administration of the last dose of the 
IMP (week 36). Patients will return for a follow-up visit (visit 12) to evaluate ADAs, biomarkers, 
and safety (adverse events and concomitant medications) approximately 7.5 months after the last 
dose of the IMP. Patients who withdraw from the study before completing the 40-week treatment 
period will have EOT visit procedures and assessments performed on the last day the patients 
received the IMP or as soon as possible thereafter, and they will be asked to return for a 
follow-up visit approximately 7.5 months after their last dose of the IMP.
Patients who enter the long-term safety follow-up study for safety follow-up only will not follow 
the same visit schedule as that for patients receiving treatment. The procedures and assessments 
for the patients participating in the safety follow-up are described in Table 5. 
CH attack information will be captured daily throughout the treatment period (ie, visit 1 [week 0] 
through visit 11 [week 40]) using an electronic diary device. Assessments of change in quality of 
life, satisfaction with treatment, 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 Patient Perceived Satisfactory Improvement 
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 pre-specified time points.
The long-term 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 assessments, assessments for anaphylaxis and 
hypersensitivity, and administration of the eC-SSRS.

Wearable Sensor Substudy: Patients rolling over from the Phase 3 pivotal efficacy studies who 
also enrolled in the wearable sensor substudy will be allowed to continue in this substudy during 
this long-term safety extension study provided they consent to continuing their participation. 
These patients will return to the investigational center for up to 2 additional visits after any dose 
of the IMP for blood sampling for pharmacokinetics analysis, triplicate 12-lead ECGs, and 
inquiries about adverse events and concomitant medications. After 15 June 2018, only patients 
who participated in the ECH study (Study TV48125-CNS-30056) will be enrolled for active 
treatment. All CCH patients included in this study have been asked to discontinue treatment and 
are encouraged to continue in the ADA and safety follow-up portion of this study.
Brief Summary of Study Design for the Trial Registry(s):
This is a 68-week extension study to evaluate the long-term safety and efficacy of fremanezumab 
in adult patients with CH. Patients who complete the pivotal studies and enroll into the current 
study (at visit 1 [week 0]) will visit the investigational center approximately every 4 weeks for 
36 weeks for IMP administration (fremanezumab at 675 mg sc quarterly, 225 mg sc monthly, or 
a loading dose of 675 mg sc followed by 225 mg sc monthly), safety assessments, and blood and 
urine collections for pharmacokinetics, immunogenicity (ADAs), and biomarker analyses. An 
EOT visit will occur approximately 4 weeks after administration of the last dose of IMP. Patients 
will return to the investigational center for a follow-up visit to evaluate ADAs, biomarkers, and 
safety (adverse events and concomitant medications) approximately 7.5 months after the last 
dose of IMP.
The long-term 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 assessments, assessments for anaphylaxis and 
hypersensitivity, and administration of the eC-SSRS. 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, satisfaction with treatment, and health status. 
In addition, blood will be collected for pharmacokinetics, immunogenicity, and biomarkers, 
(blood for pharmacogenomics is collected during the pivotal studies), and urine will be collected 
for biomarker analysis.
Method of Randomization and Blinding:
This is a double-blind study; blinding will be retained from the pivotal studies and throughout 
this long-term safety extension study. Patients will be assigned to treatments as described in 
Table 1 based on their randomization in the pivotal studies (Studies TV48125-CNS-30056 and 
TV48125-CNS-30057). Refer to the protocols for the pivotal studies 
(Studies TV48125-CNS-30056 and TV48125-CNS-30057) for details regarding randomization 
of patients in this study. After 15 June 2018, only patients who participated in the ECH study 
(Study TV48125-CNS-30056) will be enrolled for active treatment.
Packaging vendor(s) will package test IMP and placebo IMP into single-visit kits according to 
Good Manufacturing Practice procedures. Kits will be identical in appearance. Adequate kit 
supply for upcoming study visits will be managed by interactive response technology (IRT) and 
kept (refrigerated at 2°C to 8°C) at the investigational centers.

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04

At visits 1 through 10, the IRT will be queried, and investigational center personnel will retrieve 
and administer each prefilled syringe contained in the appropriately numbered kit(s). Kit 
numbers will be entered into the case report form.
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.

Patients who received fremanezumab during the pivotal studies at 225 mg sc monthly after a 
loading dose of 900-mg intravenously or 675 mg sc or fremanezumab at 675 mg sc quarterly 
during the pivotal studies will continue receiving the same dose (ie, 225 mg sc monthly or 
675 mg sc quarterly depending upon their diagnosis and randomization in the pivotal studies) 
during this long-term safety extension study. These dose regimens are expected to maintain
steady state at a blood concentration level that will provide clinical efficacy. The doses and

dosing regimens also account for the natural history of the 2 forms of CH; patients with ECH are 
likely to remit after initial treatment whereas CCH patients are continuously inflicted by pain. 
Patients who received placebo during the pivotal studies will be assigned to receive either 
fremanezumab 675 mg sc quarterly (patients with ECH from Study TV48125-CNS-30056) or a 
loading dose 675 mg sc followed by monthly fremanezumab at 225 mg sc monthly (patients with 
CCH from Study TV48125-CNS-30057). This will provide these patients with the opportunity to 
receive potential benefit from therapeutic doses including the loading dose of 675 mg sc. After 
15 June 2018, only patients who participated in the ECH study (Study TV48125-CNS-30056) 
will be enrolled for active treatment. All CCH patients included in this study have been asked to 
discontinue treatment and are encouraged to continue in the ADA and safety follow-up portion 
of this study. At the time of unblinding the treatment code in Study TV48125-CNS-30057 
(planned for Q4 2018), those CCH patients who were receiving placebo in 
Study TV48125-CNS-30057 (ie, never received any study drug) will not be required to complete
further safety follow-up visits and will be discharged from the study.
When the cluster cycle is almost over in ECH, the number of headache attacks per day start to 
decrease with associated mild to moderate intensity. Patients often look for preventive options in 
the very early part of the headache cycle in an attempt to reduce its duration. Equally, when 
complete remission is achieved patients with ECH consider stopping their medication and thus 
withdraw from treatment when the cluster period is over (May 2005). Accordingly, continuous 
long-term treatment in ECH might not be needed as these patients may have long remission 
periods between the cluster episodes. Patients with CCH may face a different situation, where the 
remission period is very short (less than a month). These patients might be more inclined to 
continue with long-term preventive treatment. Thus, the current study will evaluate the concept 
of intermittent treatment in both ECH and CCH; IMP administration may be discontinued in 
patients with CH remission (defined in ECH as patients with at least 12 successive weeks of no 
CH attacks at any time after starting IMP and in CCH as patients with at least 24 successive 
weeks of no CH attacks at any time after starting IMP).
Differentiating between remission periods lasting 12 weeks or less and remission period lasting 
more than 12 weeks after treatment has been stopped, dictates the need for the administration of 
a loading dose of fremanezumab at 675 mg sc when remission lasted for more than 12 weeks (as 
most of the drug is eliminated after 12 weeks). Thereafter, the doses and dosing regimens are 
identical to those in the pivotal studies for each CH form (ie, 225 mg sc monthly for CCH and 
675 mg sc quarterly for ECH). If treatment is stopped and headache attacks restart within 
12 weeks of stopping the treatment, patients will proceed with their previous dose, which is 
expected to re-establish efficacy and which maintains the differentiation between the 2 CH 
forms. After 15 June 2018, only patients who participated in the ECH study 
(Study TV48125-CNS-30056) will be enrolled for active treatment.

Statistical Considerations:
Sample Size Rationale: Up to 600 patients from the Phase 3 pivotal efficacy studies 
(Studies TV48125-CNS-30056 and TV48125-CNS-30057) are expected to enroll in this study. 
The sample size for each of the pivotal studies TV48125-CNS-30056 for ECH and 
TV48125-CNS-30057 for CCH is approximately 300 patients. All of the 600 patients 
participating in the pivotal studies will roll over to the long-term safety study. Approximately 
360 patients (out of the completers from the pivotal studies) will be offered to receive treatment 
during 40 weeks and these patients will return for a follow-up visit approximately 7.5 months 
after the last dose of the IMP. Approximately 240 patients (including early termination patients 
in the pivotal studies) will be offered to continue in a long-term safety evaluation collecting AEs, 
SAEs, and for ADA evaluation approximately 7.5 months after administration of the last dose of 
the IMP. 
Prior to 15 June 2018, patients from ECH TV48125-CNS-30056 and CCH 
TV48125-CNS-30057 studies were enrolled. After 15 June 2018, only patients who participated 
in the ECH study (Study TV48125-CNS-30056) will be enrolled for active treatment.

All efficacy variables will be summarized descriptively overall, by indication (ECH or CCH), 
and by treatment group. For continuous variables, descriptive statistics (number of patients [n], 
mean, standard deviation [SD], and standard error of mean, median, minimum, and maximum) 
will be provided for actual values and changes from baseline to each visit. For categorical 
variables, frequency and percentage will be provided.
Baseline is defined as the baseline in the pivotal efficacy studies.
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. Summaries will 
be presented by treatment group and for all patients. 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 measurements data will be summarized 
descriptively. All values will be compared with pre-specified 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.
Suicidal ideation and behavior will be measured using the eC-SSRS. Data for patients with 
positive findings will be listed.
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: Pharmacokinetic plasma concentration results (fremanezumab) 
will be tabulated descriptively at each planned sampling time point by diagnosis (ECH or CCH) 
and by treatment.
In addition, the most appropriate population pharmacokinetic 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

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
20
Pharmacokinetics/Pharmacodynamics Analysis: The pharmacokinetics/pharmacodynamics 
parameters may be estimated by compartmental techniques. The pharmacokinetics parameters 
will be based on fremanezumab measurements. The pharmacodynamics parameters will be the 
efficacy/safety 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 parameters 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 
pharmacokinetic profile, IMP efficacy, and clinical safety will be evaluated. This ADA-impact 
analysis will be reported separately.
Exploratory Biomarker Analysis: Exploratory biomarker measurements will be made using 
appropriately validated assays. Results, if generated, will typically be expressed as % change 
from baseline and reported in a separate addendum report.
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 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.
Planned Interim Analysis: Not applicable

INTRODUCTION AND BACKGROUND INFORMATION
1.1.
Introduction
1.1.1.
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.

1.1.2.
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 
 
. 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.
1.1.3.
Study Purpose
The purpose of the current study is to evaluate the long-term safety and efficacy of 
fremanezumab administered subcutaneously (sc) to adult patients with CH.

Prior to 15 June 2018, patients rolled over from the episodic TV48125-CNS-30056 and chronic 
TV48125-CNS-30057 cluster headache studies into the Long Term Safety study 
(TV48125-CNS-30058). 
As of 15 June 2018, CCH Study TV48125-CNS-30057 was terminated based on the study 
meeting pre-specified stopping criteria (conditional power < 25%) during a planned interim 
analysis. The planned interim analysis was for futility evaluation based on 50% of patients (ie, 
the first 150 patients who had completed the study or withdrawn from the study early). An 
independent unblinded statistician from a third party performed the analysis. The futility 
evaluation was assessed using conditional power. The sponsor was notified that the conditional 
power was less than 25% for both comparisons (fremanezumab 900 mg iv loading dose group 
versus placebo or fremanezumab 675 mg sc loading dose group versus placebo). Thus, all CCH 
patients included in this study have been asked to discontinue treatment and are encouraged to 
continue in the ADA and safety follow-up portion of this study.
At the time of unblinding the treatment code in Study TV48125-CNS-30057 (planned for 
Q4 2018), those CCH patients who were receiving placebo in Study TV48125-CNS-30057 (ie,
never received any study drug) will not be required to complete additional safety follow-up 
visits, and will be discharged from the study.
As of 15 June 2018, only patients from the ECH study (Study TV48125-CNS-30056) will enroll 
in this study for active treatment.
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 

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
34
monkeys, and no toxicological concerns were identified following chronic dosing to 
experimental animals at dose levels up to 300 mg/kg/week. 
 
 
 
 
 
 
 
 
 
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.
 
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, 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 

Uncontrolled Study–Cluster Headache

Study TV48125-CNS-30058
35
(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
The clinical pharmacology development (Phase 1) program for fremanezumab in migraine 
includes 8 completed studies. A total of 318 healthy subjects were enrolled, of which 
256 subjects received at least 1 dose of fremanezumab. 
 
 
. A description of the objectives of these 6 Phase 1 studies is as follows:

Studies B0141001 and B0141002 were iv single-dose escalation PK and PD studies 
in healthy men.

Study B0141006 was a 2-cohort, placebo-controlled crossover study to examine the 
acute effects of iv administration of fremanezumab on capsaicin flare response in 
healthy men.

Study B0141007 was a parallel-group, repeat-dose PK and PD study of iv 
administration of fremanezumab in healthy men and women.

Study LBR-101-008 was a single-dose study examining the safety, tolerability, PK, 
and PD of doses up to 2000 mg of fremanezumab administered iv to healthy women.

Study LBR-101-011 was a randomized, placebo-controlled, double-blind, 
parallel-group study examining the safety, tolerability, absolute bioavailability (BA), 
and PK of 2 different single doses of fremanezumab administered iv or sc to healthy 
men and women.
Two additional Phase 1 studies, Studies TV48125-PK-10078 and TV48125-BE-10114, were 
conducted using the current validated bioanalytical method. A description of the objectives of 
these 2 Phase 1 Studies is as follows:

Study TV48125-PK-10078 was a randomized, double-blind, placebo-controlled study 
to assess the PK, safety, and tolerability of single-dose sc administration of 
fremanezumab (single ascending doses and single doses up to 900 mg) in Japanese 
and Caucasian healthy subjects.

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
36

Study TV48125-BE-10114 was an open-label, single-dose, randomized, parallel, 
bioequivalence study to compare the PK of fremanezumab administered sc using an 
auto-injector or a pre-filled syringe in healthy adult men and women.
Additional ongoing bioequivalence study (TV48125-BE-10145) is another open-label, 
single-dose, randomized, parallel, bioequivalence study to compare the PK of fremanezumab 
administered sc using an auto-injector or a pre-filled syringe in healthy adult men and women.
The pharmacokinetics (non-compartmental analysis; Study TV48125-PK-10078) of 
fremanezumab demonstrated an increase in Cmax and AUC values slightly greater than the dose 
proportionality over the sc dose range of 225 to 900 mg. Median time to maximum observed 
concentration (tmax) values was generally 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-mg 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. 
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. 
No clinically relevant changes in clinical laboratory values, vital signs measurements, or 
electrocardiogram (ECG) findings have been observed in any of the studies to date. 
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.

37
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 swelling, injection site pain, injection site pruritus, injection site dermatitis, injection site 
rash, injection site edema, 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, injection site rash, injection site induration, and injection site pruritus. 
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 fremanezumab 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. 
1.3.2.
Overall Benefit and Risk Assessment for This Study
In summary, the benefit and risk assessment for fremanezumab is favorable following review of 
the outlined data. 
The benefit and risk assessment for fremanezumab has been re-assessed for patients with CCH. 
As of 15 June 2018, the CCH study (Study TV48125-CNS-30057) was terminated based on the 
study meeting pre-specified stopping criteria (conditional power < 25%) during a planned 
interim analysis. Thus, all CCH patients included in this study have been asked to discontinue 
treatment and are encouraged to continue in the ADA and safety follow-up portion of this study.

Objectives
Endpoints
The immunogenicity 
objective is to evaluate the 
immunogenicity of 
fremanezumab and the impact 
of antidrug antibodies (ADAs) 
on clinical outcomes in patients 
exposed to fremanezumab
The immunogenicity endpoints are ADA incidence and 
characteristics (eg, titer, kinetics, and neutralizing activities)
2.1.1.
Justification of Primary Endpoint
The primary endpoints are standard safety endpoints for clinical studies to evaluate the long-term 
safety of a drug. Endpoints related to injection site reactions/injection site pain and 
anaphylaxis/hypersensitivity reactions are included based on identified risks of fremanezumab

STUDY DESIGN
3.1.
General Design and Study Schematic Diagram
This is a 68-week extension study to evaluate the long-term safety and efficacy of fremanezumab
in adult patients with CH. During the course of any CH attack, patients will be allowed to use 
acute medications to treat acute headaches, as needed (PRN).
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 this study protocol) 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-CNS-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.
Prior to 15 June 2018, up to 360 eligible patients with ECH and CCH rolling over from the 
pivotal studies (Studies TV48125-CNS-30056 and TV48125-CNS-30057, respectively) will 
receive fremanezumab during this study, as summarized in Table 3. After 15 June 2018, only 
patients who participated in the ECH study (Study TV48125-CNS-30056) will be enrolled in this 
study for active treatment. At the time of unblinding the treatment code in
Study TV48125-CNS-30057 (planned for Q4 2018), those CCH patients who were receiving 
placebo in Study TV48125-CNS-30057 (ie, never received any study drug) will not be required 
to complete additional safety follow-up visits, and will be discharged from the study.

a In order to maintain blinding throughout the study, the number of sc injections at each visit will be the same for all 
patients rolling over from Study TV48125-CNS-30056, regardless of their assigned treatment group. Thus, 
patients will receive 3 sc injections of test IMP (1.5-mL injections each containing fremanezumab at a 
concentration of 150 mg/mL) or 1 sc injection of test IMP (1.5-mL injection containing fremanezumab at a 
concentration of 150 mg/mL) and 2 sc injections of placebo IMP (1.5-mL injections) at visits 1, 4, 7, and 10, and a 
single sc injection of test IMP or placebo IMP at visits 2, 3, 5, 6, 8, and 9.
b In order to maintain blinding throughout the study, the number of sc injections at each visit will be the same for all 
patients rolling over from Study TV48125-CNS-30057, regardless of their assigned treatment group. Thus, 
patients will receive 3 sc injections of either test IMP (1.5-mL injections each containing fremanezumab at a 
concentration of 150 mg/mL) or 1 sc injection of test IMP (1.5-mL injection containing fremanezumab at a 
concentration of 150 mg/mL) and 2 sc injections of placebo IMP (1.5-mL injections) at visit 1, and patients will 
receive a single sc injection of test IMP (1.5-mL injection containing fremanezumab at a concentration of 
150 mg/mL) at all other visits.
c Fremanezumab at 900 mg iv at visit 2 (week 0) of the pivotal study and fremanezumab at 225 mg sc at visits 3 and 
4 (weeks 4 and 8, respectively) of the pivotal study.

CCH=chronic cluster headache; ECH=episodic cluster headache; IMP=investigational medicinal product; 
iv=intravenous; sc=subcutaneous.
Patients with a diagnosis of ECH who experience CH remission, defined as no CH attacks for 
12 successive weeks at any time after starting IMP (ie, administration of the first dose of IMP in 
the pivotal study), will be offered the possibility to stop treatment and continue to attend the 

Uncontrolled Study–Cluster Headache

44
subsequent scheduled visits. If treatment is stopped and CH attacks resume within 12 weeks after 
stopping treatment, patients will restart treatment at their previous dose regimen through 
week 36. If treatment is stopped and CH attacks resume after more than 12 weeks after stopping 
treatment, patients will restart fremanezumab treatment at 675 mg sc quarterly through week 36.
Patients with a diagnosis of CCH who experience CH remission, defined as no CH attacks for 
24 successive weeks at any time after starting IMP (ie, administration of the first dose of IMP in 
the pivotal study), will be offered the possibility to stop treatment and continue to attend the 
subsequent scheduled visits. If treatment is stopped and CH attacks resume within 12 weeks after 
stopping treatment, patients will restart fremanezumab treatment at 225 mg sc monthly through 
week 36. If treatment is stopped and CH attacks resume after more than 12 weeks after stopping 
treatment, patients will restart fremanezumab treatment with a 675-mg sc loading dose followed 
by 225-mg sc monthly through week 36. After 15 June 2018, only patients who participated in 
the ECH study (Study TV48125-CNS-30056) will be enrolled for active treatment. All CCH 
patients included in this study have been asked to discontinue treatment and are encouraged to 
continue in the ADA and safety follow-up portion of this study.
All patients will return to the investigational center approximately every 4 weeks after 
administration of the first dose of the IMP (visit 1 [week 0]) through the end-of-treatment (EOT) 
visit (visit 11 [week 40]), which will occur approximately 4 weeks after administration of the last 
dose of the IMP (week 36). Patients will return for a follow-up visit (visit 12) to evaluate ADAs, 
biomarkers, and safety (adverse events and concomitant medications) approximately 7.5 months 
after the last dose of the IMP. Patients who withdraw from the study before completing the 
40-week treatment period will have EOT visit procedures and assessments performed on the last 
day the patients received the IMP or as soon as possible thereafter, and they will be asked to 
return for a follow-up visit approximately 7.5 weeks after their last dose of IMP.
Patients who enter the long-term safety follow-up study for safety follow-up only will not follow 
the same visit schedule as that for patients receiving treatment. The procedures and assessments 
for the patients participating in the safety follow-up are described in Table 5.
CH attack information will be captured daily throughout the treatment period (ie, visit 1 [week 0] 
through visit 11 [week 40]) 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 Patient-Perceived Satisfactory 
Improvement [PPSI] and the Patient Global Impression of Change [PGIC] scale); safety 
evaluations; blood collection for pharmacokinetic, immunogenicity, and biomarker analyses; and 
urine sampling for biomarker analysis will be performed at pre-specified time points (Table 4). 
The long-term 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 assessments, assessments for anaphylaxis and 
hypersensitivity, and administration of the electronic Columbia-Suicide Severity Rating Scale 
(eC-SSRS).
The end of study is defined as the date the last patient attends the follow-up visit.
The study duration will be for approximately 42 months, from Q1/2017 to Q2/2020.

a As of 15 June 2018, only patients from the ECH study (Study TV48125-CNS-30056) will enroll in this study. As of 15 June 2018, all CCH patients included in 
this study have been asked to discontinue treatment, and are encouraged to continue in the ADA and safety follow-up portion of this study. At the time of 
unblinding the treatment code in Study TV48125-CNS-30057 (planned for Q4 2018), those CCH patients who were receiving placebo in Study 
TV48125-CNS-30057 (ie, never received any study drug) will not be required to complete additional safety follow-up visits, and will be discharged from the 
study.
b The run-in period for patients with ECH lasted at least 7 days (+3 days), and the run-in period for patients with CCH lasted at least 28 days (+3 days).
c Screening will occur at visit 1 of the Phase 3 pivotal efficacy studies. After 15 June 2018, only patients who participated in the ECH study
(Study TV48125-CNS-30056) will be enrolled for active treatment. 
d Visit 1 of this study corresponds to the EOT visit (visit 5) of the pivotal efficacy studies. The EOT visit procedures/assessments for the pivotal efficacy study 
must be completed before beginning visit 1 procedures/assessments. EOT visit procedures/assessments will not be repeated at visit 1 of this study. The EOT 
visit procedures/assessments are detailed in the protocols for Studies TV48125-CNS-30056 and TV48125-CNS-30057.

Wearable Sensor Substudy: This substudy is being conducted 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). Patients 
rolling over from the Phase 3 pivotal efficacy studies who also enrolled in the wearable sensor 
substudy will be allowed to continue in this substudy during this long-term safety extension 
study.
 
 
 
After 15 June 2018, only patients who participated in the ECH study
(Study TV48125-CNS-30056) will be enrolled for active treatment. All CCH patients included in 
this study have been asked to discontinue treatment and are encouraged to continue in the ADA 
and safety follow-up portion of this study.
3.2.
Planned Number of Patients and Countries
Prior to 15 June 2018, up to 600 patients from the Phase 3 pivotal efficacy studies (Studies 
TV48125-CNS-30056 and TV48125-CNS-30057) are expected to enroll in this study. After 
15 June 2018, only patients who participated in the ECH study (Study TV48125-CNS-30056)
will be enrolled in this study for active treatment.
The study is planned to be conducted in approximately 12 countries in approximately 
80 investigational centers. The study is expected to start in Q1/2017 (first patient in) and last 
until approximately Q2/2020 (last patient last visit).
3.3.
Justification for Study Design and Selection of Population
It is very important to recognize the significant difficulty of asking patients with CH to continue 
in a double-blind, placebo-controlled study beyond 3 months. Hence, in the current study, all 
patients will receive fremanezumab so that all patients have the opportunity to receive potential 
benefit from therapeutic doses including the loading dose of 675 mg sc. The dosing regimens 
planned for this study are consistent with dosing regimens in the pivotal studies. Refer to 
Section 5.3 for additional details regarding the rationale for the doses and dose regimens.
This study is double-blind to ensure impartiality in evaluating the long-term safety and efficacy 
of different dose regimens of fremanezumab and to avoid unblinding the pivotal studies before 
they are completed. The blind will be maintained according to standard blinding procedures (see 
Section 5.9.2) and through the use of dummy injections to ensure that number of injections is the 
same at each visit for patients with ECH and patients with CCH (see Section 5.1.1.1). After 
15 June 2018, only patients who participated in the ECH study (Study TV48125-CNS-30056)
will be enrolled for active treatment.
The study population will be composed of male and female patients, aged 18 to 70 years, 
inclusive, with a history of CCH or ECH (as defined by International Classification of Headache 
Disorders-third edition beta [ICHD-3 beta] criteria [Headache Classification Committee of the 
IHS 2013]) for at least 12 months prior to screening. Concomitant medications that are 
commonly prescribed for the preventive treatment of CH (listed in Appendix H) are prohibited 
throughout this study so that effects of the test IMP can be distinguished from effects of these 
concomitant preventive medications. Thus, patients who were taking concomitant preventive 

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
49
medications during the pivotal studies will be required to taper off these medications during the 
first month of treatment in this study.
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
There are no formal rules for early termination of this study. During the conduct of the study, 
serious adverse events will be reviewed (see Section 7.1.5) as they are reported from the 
investigational 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 that:

new toxicological or pharmacological findings or safety issues invalidate the earlier 
positive benefit-risk assessment

discontinuation of the development of the IMP
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 Appendix C, 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, or indirect], or international normalized ratio [INR]) may meet 
criteria for discontinuation from the IMP as summarized in Appendix J.
3.5.
Schedule of Study Procedures and Assessments
Study procedures and assessments with their time points for patients enrolling in this study from 
the pivotal efficacy studies for treatment are presented in Table 4. Assessments and procedures 
for patients rolling over from the pivotal efficacy studies for the purpose of evaluating ADAs and 
safety (adverse events and concomitant medications) only is presented in Table 5. Detailed 
descriptions of each method of procedures and assessments are provided in Section 6 (efficacy 
assessments), Section 7 (safety assessments), and Section 8 (pharmacokinetics and other 
assessments). Study procedures and assessments by visit are listed in Appendix B.

a An unscheduled visit may be performed at any time during the study at the patient’s request and as deemed necessary by the investigator. The date and reason 
for the unscheduled visit will be recorded on the CRF as well as any other data obtained from procedures and assessments.
b Visit 1 of the current study corresponds with the EOT visit (visit 5) of the pivotal efficacy studies. EOT visit procedures/assessments must be completed before 
the patient begins participation in this study, and the EOT procedures/assessments will not be repeated at visit 1 of this study. The EOT visit 
procedures/assessments are detailed in the protocols for Studies TV48125-CNS-30056 and TV48125-CNS-30057. 
c For patients who discontinue the study early and patients who achieve CH remission (ie, meaning they stop and may restart treatment depending upon whether 
or not CH attacks recur), the follow-up visit will be approximately 7.5 months after the last dose of IMP.
d In addition to the patient, the partner or family member who will complete the Impact on Partner and Family questionnaire, if applicable, will also provide 
written informed consent. 
e Patients participating in the wearable sensor substudy will be asked to provide consent to continue participating in the substudy during this long-term safety 
study.
f Current preventive medication should be tapered over 1 month from the beginning of participation in this study.
g Procedure/assessment will be performed before blood draws and administration of questionnaires.
h Electrocardiograms will be performed in triplicate, with approximately 1 to 5 minutes between recordings.
i Adverse events will be recorded from the time informed consent for this study is obtained through the end of study participation. Inquiries about adverse events 
will be made at every visit. At visits 1 through 10 inquiries about adverse events will be made before and after dosing of the IMP.

medication and oxygen use) daily into the electronic diary device through visit 11 (week 40). 
r Blood samples for pharmacokinetic analysis will be collected prior to dosing, where applicable. Patients who signed consent for the wearable sensor substudy 
(at the pivotal studies) only will return to the investigational center for up to 2 additional visits after any dose of the IMP for blood sampling for 
pharmacokinetics analysis, triplicate12-lead ECGs, and inquiries about adverse events and concomitant medications. These visits should occur during the 
following time periods relative to any dose of the IMP: 3 to 10 days or 15 to 20 days after IMP.
s Blood samples for serum ADA assessment (
) will also be collected upon observation of any severe hypersensitivity reaction and anaphylaxis.
t 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.
u 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.
v In addition to the time points presented in this table, patients will also complete this procedure/assessment at week 1. Patients will record responses at week 1 in 
the electronic diary, and responses at all other time points will be recorded in the site tablet.
w Patients rolling over from the Phase 3 pivotal efficacy studies who also enrolled in the wearable sensor substudy will be allowed to continue in the substudy 
during this long-term safety study provided they consent to continuing their participation at visit 1. Patients will be required to wear the digital wearable device 
on the wrist continuously throughout the treatment period of this study.
x Doses/dosing regimens will be assigned based on randomization in the pivotal studies, and dummy placebo sc injections will be administered to maintain 
blinding. Refer to Table 3 and Section 5.1.1.1 for additional details.
y Injection sites will be assessed for erythema, induration, ecchymosis, and pain immediately (+10 minutes) and 1 hour (±15 minutes) after IMP administration. 
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 
3 hours (±15 minutes) after IMP administration and hourly (±15 minutes) thereafter until the reaction is of moderate or less severity.

SELECTION AND WITHDRAWAL OF PATIENTS
Prospective waivers (exceptions) from study inclusion and exclusion criteria to allow patients to 
be enrolled are not granted by Teva (Appendix C). Any deviation from the eligibility criteria will 
result in study drug discontinuation in the event that a patient has not been dosed.
4.1.
Patient Inclusion Criteria
Patients may be included in the treatment portion of the study only if they meet all of the 
following criteria:
a.
The patient is a male or female and 18 to 70 years of age, inclusive, at the start of the 
pivotal study.
b. The patient signs and dates the informed consent document.
c.
The patient completes either the Phase 3 pivotal study for ECH 
(Study TV48125-CNS-30056) or the Phase 3 pivotal study for CCH 
(Study TV48125-CNS-30057) without important protocol deviations related to 
patient safety and patient compliance and at least 75% diary data completion during 
the pivotal study. Prior to 15 June 2018, patients from the ECH study and the CCH 
study were enrolled. After 15 June 2018, only patients who participated in the ECH 
study (Study TV48125-CNS-30056) will be enrolled for active treatment.

In addition, patients who do not complete the pivotal efficacy studies, and patients 
who complete the pivotal efficacy studies but do not wish to continue treatment 
during this long-term safety study, will be offered to enroll in this 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 the 
IMP.
d. Women may be included only if they have a negative beta-human chorionic 
gonadotropin (β-HCG) test at visit 1, are sterile or postmenopausal, and are not 
lactating (not applicable for patients participating in safety follow-up only). 
Definitions of sterile and postmenopausal are given in Appendix E.
e.
Women of childbearing potential (WOCBP) whose male partners are potentially 
fertile (ie, no vasectomy) must use highly effective birth control methods 
(see Appendix E) for the duration of the study and for 7.5 months after 
discontinuation of IMP.
Men must be sterile or, if they are potentially fertile/reproductively competent (not 
surgically [eg, vasectomy] or congenitally sterile), and their female partners are of 
childbearing potential, must agree to use, together with their female partners, 
acceptable birth control methods for the duration of the study and for 7.5 months after 
administration of IMP. 
Definitions of women of non-childbearing potential, sterile and postmenopausal 
women; male contraception; and highly effective and acceptable birth control 
methods, including examples, are given in Appendix E.

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
56
f.
The patient must be willing to stop concomitant medications used in clinical practice 
for the prevention of CH (ie, verapamil, topiramate, valproate, lithium, or 
methysergide) for the duration of this study. Patients must begin tapering these 
preventive medications as soon as they begin this study. The period of time needed to 
taper off these medications will be based on the investigator’s medical judgment but 
should not exceed 1 month from the beginning of participation in this study 
(Appendix H) (not applicable for patients participating in safety follow-up only).
g. The patient is in good health in the opinion of the investigator, as determined by a 
medical and psychiatric history; medical examination; 12-lead ECG; and serum 
chemistry, hematology, coagulation, and urinalysis (not applicable for patients 
participating in safety follow-up only).
h. The patient must be willing and able to comply with study restrictions to remain at 
the clinic for the required duration during the study period and to return to the clinic 
for the follow-up evaluations, as specified in this protocol.
4.2.
Patient Exclusion Criteria
Patients will be excluded from participating in the treatment portion of this study if they meet 
any of the following criteria:
a.
The patient has a history of any suicide attempt in the past or current active suicidal 
ideation, as measured by the eC-SSRS.
b. Any finding in the 12-lead ECG performed as part of the EOT visit (visit 5) 
procedures for the pivotal studies considered clinically significant in the judgment of 
the investigator.
c.
Any finding that, in the judgment of the investigator, is a clinically significant 
abnormality, including serum chemistry, hematology, coagulation, and urinalysis test 
values (abnormal tests may be repeated for confirmation).
d. Hepatic enzymes (ALT and AST) >1.5 × the upper limit of the normal range (ULN) 
after confirmation in a repeat test or suspected hepatocellular damage that fulfills 
criteria for Hy’s law.
e.
Serum creatinine >1.5 × the ULN or evidence of clinically significant renal disease in 
the judgment of the investigator.
Patients rolling over only for safety follow-up and ADA who are not receiving study medication 
are not required to fulfil all inclusion exclusion criteria.
4.3.
Withdrawal Criteria and Procedures for the Patient
Each patient is free to withdraw from this study at any time, without prejudice to their continued 
care. Patients must be withdrawn from this study if any of the following events occur:
1. Patient withdraws consent or requests discontinuation from this study for any reason.
2. Patient develops an illness that would interfere with his/her continued participation.

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
57
3. Patient is noncompliant with the study procedures and assessments or administration of 
IMPs (including noncompliance with wearable sensor substudy, if applicable) in the 
opinion of the investigator.
4. Patient takes prohibited concomitant medications as defined in this protocol.
5. A female patient has a confirmation of pregnancy during the study from a positive 
pregnancy test result.
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 enrolled 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.
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. 

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
58
All protocol-specified procedures/assessments should be performed at the early withdrawal visit 
(see Table 4). Patients who withdraw from the study will not be replaced. 
A patient should only be designated as lost to follow-up if the investigational center 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 enrolled but does not complete the treatment period will not be replaced.
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.

5.1.1.
Test Investigational Medicinal Product
Fremanezumab is a fully humanized IgG2a/kappa monoclonal antibody derived from a murine 
precursor. Additional details may be found in Table 6 and in the IB for fremanezumab. 
5.1.1.1.
Starting Dose and Dose Levels
Patients rolling over from Study TV48125-CNS-30056 with ECH:

Patients who were in the fremanezumab 900-mg iv loading dose group will receive 
fremanezumab at 225 mg sc as a single injection at visit 1 and every 4 weeks 
thereafter through week 36 (visit 10). For blinding, these patients will also receive 
2 placebo sc injections at visits 1, 4, 7, and 10.

Patients who were in the placebo group and the fremanezumab 675-mg sc quarterly 
group will receive fremanezumab at 675 mg sc as 3 injections (225 mg/1.5 mL) at 
visit 1 and every 12 weeks thereafter through week 36 (visit 10). For blinding, 
patients will receive 1 single placebo sc injections at visits 2, 3, 5, 6, 8, and 9.
 
 
 
 
 
 
After 15 June 2018, only patients who participated in the ECH study
(Study TV48125-CNS-30056) will be enrolled for active treatment. Patients with CCH will be 
rolled over from Study TV48125-CNS-30057 until 15 June 2018 as follows (after 15 June 2018 
no additional CCH patients will be enrolled):

Patients who were in the fremanezumab 900-mg iv loading dose group and the 
fremanezumab 675-mg sc loading dose group will receive fremanezumab at 225 mg 
as a single sc injection (225 mg/1.5 mL) at visit 1 and every 4 weeks thereafter 
through week 36 (visit 10). For blinding, these patients will also receive 2 sc placebo 
injections at visit 1. 

Patients who were in the placebo group will receive a loading dose of fremanezumab 
at 675 mg as 3 sc injections (225 mg/1.5 mL) at visit 1 and fremanezumab at 225 mg 
administered as a single sc injection every 4 weeks thereafter through week 36 
(visit 10). 
 
 
 
 
 
 After 15 June 2018, only patients who participated in 

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
61
the ECH study (Study TV48125-CNS-30056) will be enrolled for active treatment. All CCH 
patients included in this study have been asked to discontinue treatment and are encouraged to 
continue in the ADA and safety follow-up portion of this study. At the time of unblinding the 
treatment code in Study TV48125-CNS-30057 (planned for Q4 2018), those CCH patients who 
were receiving placebo in Study TV48125-CNS-30057 (ie, never received any study drug) will 
not be required to complete additional safety follow-up visits, and will be discharged from the 
study.
Of note, blinding of the pivotal studies and the initial treatments during this long-term safety 
extension study will be maintained throughout study participation.
5.1.2.
Placebo Investigational Medicinal Product
The placebo will be the same vehicle and excipients as those for fremanezumab. See Table 6 for 
additional details. 
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
As noted in Section 5.1.1.1, as of June 15 2015, CCH patients are no longer enrolling in this
study.
Patients who received fremanezumab at 225 mg sc monthly after a loading dose of 900-mg iv or 
675 mg sc or fremanezumab at 675 mg sc quarterly during the pivotal studies will continue 
receiving the same dose (ie, 225 mg sc monthly or 675 mg sc quarterly depending upon their 
diagnosis and randomization in the pivotal studies) during this long-term safety extension study. 
These dose regimens are expected to maintain steady state at a blood concentration level that will 
provide clinical efficacy. The doses and dosing regimens also account for the usual course of the 
2 forms of CH; patients with ECH are likely to remit after initial treatment whereas CCH patients 
are continuously inflicted by pain. 
Patients who received placebo during the pivotal studies will be assigned to receive either 
fremanezumab 675 mg sc quarterly (patients with ECH from Study TV48125-CNS-30056) or a 
loading dose 675 mg sc followed by monthly fremanezumab at 225 mg sc monthly (patients with 
CCH from Study TV48125-CNS-30057). This will provide these patients with the opportunity to 
receive potential benefit from therapeutic doses including the loading dose of 675 mg sc.
In addition to evaluating maintenance of efficacy in this long-term safety extension study, the 
planned treatments account for the need to adjust treatment duration, which is of particular 
relevance for ECH. When the cluster cycle is almost over in ECH, the number of headache 
attacks per day start to decrease with associated mild to moderate intensity. Patients often look 
for preventive options in the very early part of the headache cycle in an attempt to reduce its 
duration. Equally, when complete remission is achieved, patients with ECH consider stopping 

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
62
their medication and thus withdraw from treatment when the cluster period is over (May 2005). 
Accordingly, continuous long-term treatment in ECH might not be needed as these patients may 
have long remission periods between the cluster episodes.
 
 
 
 
 
 
 
 
 
 
 
. 
5.4.
Restrictions
Patients will be required to comply with the following restrictions:
5.4.1.
Activity
Patients must remain at the investigational center for safety observation for at least 60 minutes 
after IMP administration. Patients may be asked to remain at the investigational center longer if 
it is judged to be medically necessary. 
5.4.2.
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.
5.4.3.
Pregnancy
Restrictions in regard to pregnancy are provided in the inclusion criteria (Section 4.1). 
Restrictions in regard to sexual activity are also detailed in the inclusion and exclusion criteria 
(Section 4.1), and contraception methods are reviewed in Appendix E.
In addition, male patients may not donate sperm for the duration of the study and for 7.5 months 
(approximately 5 half-lives of the active IMP) after administration of the last dose of the IMP.
5.5.
Prior and Concomitant Medication or Therapy
Any concomitant medication, treatment, or procedure from the time of consent up to the end of 
the study, including follow-up, will be recorded on the CRF. Trade name and International 
Nonproprietary Names (if available), indication, dose, and start and end dates of the administered 

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
63
medication will be recorded. The sponsor will encode all medication and treatment according to 
the World Health Organization drug dictionary.
Patients taking concomitant preventive medications (ie, verapamil, topiramate, valproate, 
lithium, or methysergide) during the pivotal studies must begin tapering as soon as they begin 
participation in this study, and they must be off these medications within 1 month from the 
beginning of participation in this study (not applicable for patients participating in safety follow-
up only). See Appendix H for details. 
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.
5.6.
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.
5.7.
Temporary Discontinuation of Investigational Medicinal Product
Patients who experience CH remission, defined as no CH attacks for 12 successive weeks and 
24 successive weeks for patients with ECH and CCH, respectively, at any time after starting IMP 
(ie, administration of the first dose of IMP in the pivotal study) will be offered the possibility to 
stop treatment. Patients will restart fremanezumab treatment if treatment is stopped and CH 
attacks resume during the 36-week double blind treatment period. Refer to Section 5.1.1.1 for 
additional details regarding treatment of these patients. After 15 June 2018, only patients who 
participated in the ECH study (Study TV48125-CNS-30056) will be enrolled for active 
treatment.
5.8.
Randomization and Blinding
This is a double-blind study; blinding will be retained from the pivotal studies and throughout 
this long-term safety extension study. Patients will be assigned to treatments as described in 
Table 3 and Section 5.1.1.1 based on their randomization in the pivotal studies 
(Studies TV48125-CNS-30056 and TV48125-CNS-30057).

Maintenance of Randomization and Blinding
5.9.1.
Maintenance of Randomization
Refer to the protocols for the pivotal studies (Studies TV48125-CNS-30056 and 
TV48125-CNS-30057) for details regarding randomization of patients in this study. 
Packaging vendor(s) will package test IMP and placebo IMP into single-visit kits according to 
Good Manufacturing Practice (GMP) procedures. Kits will be identical in appearance. Adequate 
kit supply for upcoming study visits will be managed by interactive response technology (IRT) 
and kept (refrigerated at 2°C to 8°C) at the investigational centers. 
At visits 1 through 10, the IRT will be queried, and investigational center personnel will retrieve 
and administer each prefilled syringe contained in the appropriately numbered kit(s). Kit 
numbers will be entered into the CRF. 
5.9.2.
Blinding and Unblinding
Blinding will be retained from the pivotal studies and throughout this long-term safety extension 
study.
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).
For information about personnel who may be aware of IMP assignments, see Section 5.8 of the 
pivotal efficacy protocols. These individuals will not be involved in conduct of any study 
procedures or assessment of any adverse events.
In the event of an emergency, it will be possible to determine which treatment group and dose 
the patient has been allocated to by accessing the Randomization and Trial Supply Management 
(RTSM) system. All investigational centers will be provided with details of who can access the 
system for code breaking at the start of the study. The Medical Monitor or equivalent should be 
notified following unblinding. Any unblinding of the IMP performed by the investigator must be 
recorded in the source documents.
In case of a serious adverse event, pregnancy, or in cases when knowledge of the IMP 
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 RTSM system. Breaking of the treatment code can always be performed by the 
investigator without prior approval of the sponsor; however, the sponsor should be notified that 
the code was broken, but the patient’s IMP assignment should not be revealed to the sponsor. In 
the event that the RTSM system is not functioning for emergency unblinding, the next course of 
action is to contact via phone the RTSM on-call customer support helpline for manual 
emergency unblinding.

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
65
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.

ASSESSMENT OF EFFICACY
6.1.
Assessments of Efficacy
There is no primary efficacy measure.
6.2.
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). 
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
6.3.
Hospital Anxiety and Depression Scale 
The HADS is a validated and reliable, 14-item scale developed 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 at the time points detailed in Table 4. Responses will be 
recorded in the site tablet.

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 at the time points detailed in Table 4. Responses will be 
recorded in the site tablet.
6.5.
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 at the time points detailed in Table 4. Responses will be 
recorded in the site tablet.
6.6.
Work Productivity and Activity Impairment Questionnaire
The generic version of the WPAI questionnaire measures the overall effect of health on 
productivity at work and daily activities. The specific health problems version of the WPAI 
questionnaire allows investigators to attribute productivity and activity impairment issues to 
specific health conditions. After the employment status of a respondent is identified, 
3 open-ended questions are asked concerning (1) hours absent from work due to health problems 
(or specific condition), (2) hours absent from work due to other reasons, and (3) hours actually 
worked. Two additional questions are included that ask about the impact of health on 
productivity, 1 concerning productivity at work and the other concerning daily activities outside 
of work. The response format of each item of the WPAI questionnaire consists of an 11-point 
scale ranging from 0 (no impairment) to 10 (complete impairment) (Reilly et al 1993). 
Patients will complete the WPAI questionnaire at the time points detailed in Table 4. Responses 
will be recorded in the site tablet.
6.7.
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 4. Responses 
will be recorded in the 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 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. 
6.8.
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 at time points detailed in Table 4. Responses at week 1 will be 
entered into the electronic diary device, and responses at all other time points will be entered into 
the site tablet.
6.9.
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.”
The PGIC scale will be completed at the time points detailed in Table 4. Responses at week 1 
will be entered into the electronic diary device, and responses at all other time points will be 
entered into the site tablet.

ASSESSMENT OF SAFETY
In this study, safety will be assessed by qualified study personnel by evaluating reported adverse 
events, reported anaphylaxis/hypersensitivity reactions, clinical laboratory test results, vital signs 
measurements, ECG findings, physical examination findings (including body weight 
measurements), injection site assessment results, eC-SSRS responses, 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 the 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 or diagnostic 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 the 1st dose of IMP but after obtaining informed consent 
will be recorded on the Medical History/Current Medical Conditions section of the CRF.

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 informed consent form (ICF) through the follow-up visit. 
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), 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 7):
Table 7:
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.
IMP=investigational medicinal product.
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 end of the follow-up period. Serious adverse events 
occurring in a patient after the end of the follow-up 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.

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04

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

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:

ALT or AST increase of ≥3 × the ULN

total bilirubin increase of ≥2 × 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.
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

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
74

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

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 Boards (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.
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

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04

75

modifying listings of expected toxicities to include adverse events newly identified as 
related to fremanezumab
7.1.6.
Protocol-Defined Adverse Events not for Expedited Reporting
Not applicable
7.1.7.
Protocol-Defined Adverse Events of Special Interest
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 
adverse events of at least moderate severity, events of possible IMP-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 
reactions will be monitored using the diagnostic criteria for anaphylaxis as outlined by the 2006 
Joint National Institute of Allergy and Infectious Disease/Food Allergy and Anaphylaxis 
Network Second Symposium on Anaphylaxis (Sampson et al 2006) (also see Appendix K). 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 center 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 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 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).

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
76
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 
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 non-compliant 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.

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
77
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, transcribed to 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 cessation of treatment with IMP or medical treatment, or further 
diagnostic workup. (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 4. Clinical laboratory tests will be performed using the central 
laboratory. However, 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
Serum and urine β-HCG tests will be performed for all WOCBP at time points specified in 
Table 4. Any female patient who becomes pregnant during the study will be withdrawn. 
Procedures for reporting the pregnancy are provided in Section 7.2.

Physical Examinations
Physical examinations, including weight, will be performed at the time points detailed in
Table 4. A complete physical examination will include the following organ systems: general 
appearance; head, eyes, ears, nose, and throat; chest and lungs; heart; abdomen; musculoskeletal; 
skin; lymph nodes; and neurological. Any physical examination finding that is judged by the 
investigator as a potentially clinically significant change (worsening) compared with a baseline 
value will be considered an adverse event, recorded on the CRF, and monitored as described in
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 4. 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 4. 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 investigational centers. 
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 

Uncontrolled Study–Cluster Headache

definitive interpretation. All communications and diagnoses should be filed in the source 
documentation file. The investigator's interpretation will be recorded in the CRF regardless of 
the central reading interpretation. Any abnormal findings assessed by the investigator as 
clinically significant should be recorded in the relevant CRF modules (eg, adverse event, medical 
history).
Objective alerts are predefined as described in the central ECG reading manual. In these cases, 
the investigational center 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 clinically significant (except at the 
screening visit) 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 4
(patients enrolling in this study from the pivotal efficacy studies) and Table 5 (patients rolling 
over from the pivotal efficacy studies for evaluation of ADAs and safety [adverse events and 
concomitant medications] only). 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. After 15 June 2018, only patients who participated in the 
ECH study (Study TV48125-CNS-30056) will be enrolled for active treatment. All CCH patients 
included in this study have been asked to discontinue treatment, and are encouraged to continue 
in the ADA and safety follow-up portion of this study. At the time of unblinding the treatment 
code in Study TV48125-CNS-30057 (planned for Q4 2018), those CCH patients who were 
receiving placebo in Study TV48125-CNS-30057 (ie, never received any study drug) will not be 
required to complete additional safety follow-up visits, and will be discharged from the 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.

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
80
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 Since Last Visit version will be completed by the 
patient at every visit, 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 
seen by a mental health specialist and if he/she should continue participating in the study. If a 
patient reports current suicide ideation with a 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 usage will be monitored throughout the study. Details of 
prohibited medications are found in Section 5.5. 
7.11.
Injection Site Assessments
Injection site assessments will be performed immediately (+10 minutes) and 1 hour 
(±15 minutes) after administration of each dose of the IMP (see Table 4). The injection sites 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 mm to ≤50 mm (mild), >50 to ≤100 mm (moderate), and 
>100 mm (severe). Induration must be assessed by careful superficial palpation 
avoiding pressuring or squeezing the injection site. 

For spontaneous report of local pain after the injection, it will be measured as 
summarized in Table 8.
Table 8:

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.

ASSESSMENT OF PHARMACOKINETICS/BIOMARKERS/ 
IMMUNOGENICITY/ANCILLARY STUDIES
8.1.
Pharmacokinetics Assessment
Sampling for pharmacokinetics will be sparse. Thus, the fremanezumab pharmacokinetics 
samples will be analyzed using a population pharmacokinetic approach and will be reported 
separately from the clinical study report.
Blood samples 
 will be collected via venipuncture/indwelling catheter at the time points 
detailed in Table 4 (patients enrolling in this study from the pivotal efficacy studies). 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 all patients will be analyzed for concentration of fremanezumab using a validated 
method. Details on sample handling, storage, shipment, and analysis are given in Appendix G. 
8.2.
Pharmacodynamics Assessment
Pharmacodynamics parameters are not evaluated in this study.
8.3.
Immunogenicity Testing
Blood samples 
 will be collected via venipuncture or indwelling catheter at the time points 
detailed in Table 4 (patients enrolling in this study from the pivotal efficacy studies) and Table 5
(patients rolling over from the pivotal efficacy studies for evaluation of ADAs and safety 
[adverse events and concomitant medications] only) for immunogenicity testing. 
Samples from all patients will be analyzed. 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 preclinical models, CGRP can promote angiogenesis in ischemia, capsaicin-induced synovitis, 
and neovascularization of tumors.
 

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
83
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.
 
 
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 will be collected from each patient (unless the 
patient declines testing or local regulations prohibit testing) for pharmacogenomic assessment 
during the pivotal efficacy study. Pharmacogenomic assessment potentially includes the 
association analysis of both known and unknown DNA and RNA genetic variations.
8.6.
Ancillary Study – Wearable Sensor Substudy
At selected sites, a subset of patients (n=90, approximately 45 from each Phase 3 pivotal study) 
will be asked to wear a sensor monitoring system (digital wearable device) on the wrist to track 
sleep patterns and activity patterns. 
 
 
 
 
 
 After 15 June 2018, only patients 
who participated in the ECH study (Study TV48125-CNS-30056) will be enrolled for active 
treatment.

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
There are no statistical considerations for the sample size. Up to 600 patients from the Phase 3 
pivotal efficacy studies (Studies TV48125-CNS-30056 and TV48125-CNS-30057) are expected 
to enroll in this study
The sample size for each of the pivotal studies TV48125-CNS-30056 for ECH and 
TV48125-CNS-30057 for CCH is 300 patients. All of the 600 patients participating in the pivotal 
studies will roll over to the long-term safety study. Approximately 360 patients (out of the 
completers from the pivotal studies) will be offered to receive treatment during 40 weeks, and 
these patients will return for a follow-up visit approximately 7.5 months after the last dose of the 
IMP. Approximately 240 patients (including early termination patients in the pivotal studies) will 
be offered to continue in a long-term safety evaluation collecting AEs, SAEs, and for ADA 
evaluation approximately 7.5 months after administration of the last dose of the IMP.
Prior to 15 June 2018, patients from the ECH study and the CCH study were enrolled. After 
15 June 2018, only patients who participated in the ECH study (Study TV48125-CNS-30056) 
will be enrolled for active treatment. At the time of unblinding the treatment code in 
Study TV48125-CNS-30057 (planned for Q4 2018), those CCH patients who were receiving 
placebo in StudyTV48125-CNS-30057 (ie, never received any study drug) will not be required to 
complete additional safety follow-up visits, and will be discharged from the study.
9.2.

SUMMARY OF CHANGES TO THE PROTOCOL
16.1.
Amendment 04 Dated 28 August 2018
The primary reason for this amendment is to describe the way in which patients who participated 
in the double-blind study for CCH TV48125-CNS-30057 will continue to participate in this 
Long Term Safety study (Study TV48125-CNS-30058), since the CCH study has been 
terminated. 
Prior to 15 June 2018, patients rolled over from the episodic TV48125-CNS-30056 and chronic 
TV48125-CNS-30057 cluster headache studies into the Long Term Safety study 
(TV48125-CNS-30058).
As of 15 June 2018, the CCH Study TV48125-CNS-30057 was terminated based on the study 
meeting pre-specified stopping criteria (conditional power < 25%) during a planned interim 
analysis. Thus, all CCH patients included in this study have been asked to discontinue treatment 
and are encouraged to continue in the ADA and safety follow-up portion of this study.
After 15 June 2018, only patients who participated in the ECH study
(Study TV48125-CNS-30056) will be enrolled for active treatment. At the time of unblinding the 
treatment code in Study TV48125-CNS-30057 (planned for Q4 2018), those CCH patients who 
were receiving placebo in Study TV48125-CNS-30057 (ie, never received any study drug) will 
not be required to complete additional safety follow-up visits, and will be discharged from the 
study.
The Amendment History table has been updated to correct some inadvertent errors.
Updated standardized text has been added to Section 5.9.2.
Additional changes to the protocol are presented below.
Letters of Clarification 05, 06, and 08 and the USM Letter of Clarification have been included. 
They were inadvertently omitted from being attached to previous protocol amendments. 
However, all changes to the protocol based on these letters were made at the applicable time 
points and are noted in the correct amendments. The letters are presented at the end of this 
amendment.
Letter of Clarification 07 was inadvertently noted and was applicable only to other studies in 
Sweden (Studies TV48125-CNS-30056 and TV48125-CNS-30057).
Appropriate areas of the protocol have been updated as outlined in the table below.

planned interim analysis was for futility evaluation 
based on 50% of patients (ie, the first 150 patients 
who had completed the study or withdrawn from the 
study early). An independent unblinded statistician 
from a third party performed the analysis. The 
futility evaluation was assessed using conditional 
power. The sponsor was notified that the conditional 
power was less than 25% for both comparisons 
(fremanezumab 900 mg iv loading dose group versus 
placebo or fremanezumab 675 mg sc loading dose 
group versus placebo).Thus, all CCH patients 
included in this study have been asked to discontinue 
treatment, and are encouraged to continue in the anti-
ADA and safety follow-up portion of this study.

Section 3.3 Justification for Study Design and Selection of Population
This study is double-blind to ensure impartiality in 
evaluating the long-term safety and efficacy of
different dose regimens of fremanezumab and to 
avoid unblinding the pivotal studies before they are 
completed. The blind will be maintained according to 
standard blinding procedures (see Section 5.9.2) and 
through the use of dummy injections to ensure that 
number of injections is the same at each visit for 
patients with ECH and patients with CCH (see 
Section 5.1.1.1). After 15 June 2018, only patients 
who participated in the ECH study 
(Study TV48125-CNS-30056) will be enrolled for 
active treatment.

Amendment 03 Dated 26 April 2018
The primary reason for this amendment is to provide clarification on concomitant preventive 
medications allowed in the treatment arm of this long-term safety study (Study 
TV48125-CNS-30058). Patients who satisfactorily complete pivotal double-blind studies 
TV48125-CNS-30056 or TV48125-CNS-30057 may be offered the opportunity to enroll in 
Study 30058 either for treatment or for ADA safety follow-up, independent of their concomitant 
preventive medications (ie, verapamil, topiramate, valproate, lithium, or methysergide). For 
those continuing to receive active treatment, tapering of all concomitant preventive medications 
used in the pivotal studies will be required, which is in line with clinical practice. Tapering will 
be based on the investigator’s medical judgment but should not exceed 1 month from the 
beginning of participation in Study 30058 to avoid any potential safety concerns with abrupt 
discontinuation of these concomitant preventive medications. 
Patients in the treatment arm of Study 30058 who restart preventive medication will have to 
discontinue participation in the study per the current protocol; such cases will be treated as 
important protocol deviations. No other exceptions to the protocol will be permitted.
The number of patients who will be offered the opportunity to roll over into the treatment arm 
has been increased: approximately 360 patients may roll over for treatment. The overall sample 
size of the entire 30058 study will not change and will remain at 600 patients. Consequently, the 
number of patients who may roll over for ADA and safety follow-up only is correspondingly 
decreased: approximately 240 patients may roll over for ADA and safety follow-up. The 
justification behind this change is driven from the natural history of patients with chronic CH, 
which is characterized as less than 1 attack-free month in 1 year. Therefore, these patients want 
and have a necessity to continue treatment. This change will offer these patients the opportunity 
to roll over into the treatment arm.
Additionally, the duration of the study has been extended by 6 months because the study 
recruitment rate into Studies 30056 and 30057 has been lower than initially expected. The 
duration will be approximately 42 months, from Q1/2017 to Q2/2020. Extension of the study 
period is needed in order to meet the number of patients planned for this protocol. There is no 
change to the individual treatment period per patient. There is also no change to the procedures 
for patients in the study.
It has been clarified that pharmacogenomics samples are taken only during the pivotal studies 
and will not be collected in Study 30058. 
The assessment “Perform triplicate 12-lead ECGs” at visit 8 (week 28 ± 3 days) has been deleted 
from Appendix B. It was mistakenly added and does not align with Table 4, Study Procedures 
and Assessments for Treated Patients, which schedules triplicate 12-lead ECGs at weeks 12, 24, 
36, and 40/ end-of-study visit.
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.

Section 3.3, Justification for Study Design and Selection of Population
Concomitant medications that are commonly 
prescribed for the preventive treatment of CH (listed 
in Appendix H) are prohibited throughout this study 
so that effects of the test IMP can be distinguished 
from effects of these concomitant preventive 
medications. Thus, patients who were taking 
concomitant preventive medications (up to 2) during 
the pivotal studies will be required to stop taking
taper off these medications during the first month of 
treatment in this study.

potential safety concerns with abrupt discontinuation of 
these concomitant preventive medications. 
Section 4.1, Patient Inclusion Criteria
f. The patient must be willing to stop concomitant 
medications used in clinical practice for the 
prevention of CH (ie, verapamil, topiramate, 
valproate, lithium, or methysergide) for the duration 
of this study. (Note: Patients taking verapamil during

Appropriate tapering of these concomitant preventive 
medications can avoid risks to patients and mitigate 
causing adverse health effects.
Section 4.3, Withdrawal Criteria and Procedures for the Patient
In the event that a patient was incorrectly 
randomized enrolled 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.

Section 9.1, Sample Size and Power Considerations
All of the 600 patients participating in the pivotal 
studies will roll over to the long-term safety study. 
Approximately 300360 patients (out of the 
completers from the pivotal studies) will be offered 
to receive treatment during 40 weeks, and these 
patients will return for a follow-up visit

Amendment 02 Dated 03 May 2017
The primary reason for this amendment is to provide clarification on feedback from participating 
investigators and regulatory agencies and to incorporate nonsubstantial changes to maintain 
alignment with the protocols with protocol Amendment 02 for Studies TV48125-CNS-30056 
and TV48125-CNS-30057. 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.

Eligible patients with ECH and CCH rolling over from the pivotal 
studies (Studies TV48125-CNS-30056 and TV48125-CNS-30057, 
respectively) will receive fremanezumab during this study, as 
summarized in Table 3.
All patients will return to the investigational center approximately 
every 4 weeks after administration of the first dose of the IMP 
(visit 1 [week 0]) through the end-of-treatment (EOT) visit (visit 11 
[week 40]), which will occur approximately 4 weeks after 
administration of the lastfinal dose of the IMP (week 36). Patients 
will return for a follow-up visit (visit 12) to evaluate ADAs, 
fremanezumab concentrations, biomarkers, and safety (adverse 
events and concomitant medications) approximately 7.5 months 
after the last dose of the IMP. This visit is for the purpose of 
evaluating ADAs, fremanezumab concentrations, biomarkers, and 
safety only. Patients who withdraw from the study before 
completing the 40-week treatment period will have EOT visit 
procedures and assessments performed on the last day the patients 
received the IMP or as soon as possible thereafter, and they will be 
asked to return for a follow-up visit approximately 7.5 weeks after 
their last dose of IMP. 
Patients who enter the long-term safety follow-up study for safety 
follow-up only will not follow the same visit schedule as that for 
patients receiving treatment. The procedures and assessments for 
the patients participating in the safety follow-up are described in 
Table 5.

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.

discontinued from the study.
A positive finding will be defined as 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 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

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 Independent Ethics 
Committee/Institutional Review Board (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 Good Clinical Practice (GCP) 
guidelines; noncompliance to investigational medicinal product administration; and use of 
prohibited medications. All 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 Good Clinical Practice (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 enrolled 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 

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
183
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 
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 standard operating procedures (SOPs), the protocol, and other written 
instructions and regulatory guidelines.
The study monitor is the primary association between the sponsor and the investigator. The main 
responsibilities of the study monitor(s) are to visit the investigator before, during, and after the 
study to ensure adherence to the protocol; that all data are correctly and completely recorded and 
reported; and that informed consent is obtained and recorded for all patients before they 
participate in the study and when changes to the consent form are warranted, in accordance with 
IEC/IRB approvals.
The study monitor(s) will contact the investigator and visit the investigational center according 
to the monitoring plan. The study monitor will be permitted to review and verify the various 
records (case report forms [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 04
Study TV48125-CNS-30058
184
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 
Independent Ethics Committee/Institutional Review Board (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 (ICF), 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 ICFs, and copies will be given to the patient. It will also be explained to 
the patient that a 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 the 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 confidential at all times. In case report forms 
(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, 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 products 
(IMPs) 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, cytochrome P450 
[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 immunoglobulin G2 isotype, which 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 proinflammatory 
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. Such methods include:

Combined estrogen and progestogen hormonal contraception (oral, intravaginal, 
transdermal) associated with inhibition of ovulation; these should be initiated at least 
7 days before dosing of IMP.

Progestogen-only hormonal contraception (oral, injectable, implantable) associated 
with inhibition of ovulation; these should be initiated at least 7 days before dosing of 
IMP.

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
186

Intrauterine device and intrauterine hormone-releasing system 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; and cap, 
diaphragm, or sponge with spermicide. The combination of male condom with either 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, postovulation 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 patients 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 
pregnant.

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, 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 and placebo will be provided in prefilled syringes contained in uniquely 
numbered kits and stored (refrigerated at 2°C to 8°C) at the investigational center. At the time of
each study visit, the interactive response technology will be queried, and site personnel will 
retrieve the appropriately numbered kit(s). Kit numbers will be entered into the case report form.
Preparation instructions for subcutaneous (sc) injections: 
 
 
 A 1.5 mL volume from each syringe in each visit’s 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) and protected from light; the investigational center should have a process for monitoring 
the IMP storage temperature.
Diversion is considered to have occurred when the legal supply chain of prescription 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 
accordance with the Code of Federal Regulations 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 

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
189
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 center should provide a certificate of destruction. If the 
investigational center 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 
the IMP will be returned to the sponsor or designee.

GUIDANCE ON SAFETY MONITORING
Guidance on Monitoring Patients with Elevated Liver Function Tests
Liver enzymes (alanine aminotransferase [ALT], aspartate aminotransferase [AST], 
gamma-glutamyl transpeptidase [GGT], and alkaline phosphatase [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 upper limit of the normal 
range (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 investigational 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 international normalized ratio (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
                                                
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.


the baseline value was above the ULN and ALT or AST is ≥2 × the baseline value
Additional Tests/Evaluations:
Upon confirmation of the abnormality as noted above, the following additional evaluations 
should be performed and results should be recorded in the case report form:

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.

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
195
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 center 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], and hypoxemia)
b. reduced blood pressure or associated symptoms of end-organ dysfunction 
(eg, hypotonia [collapse], syncope, and 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, and swollen 
lips-tongue-uvula)
b. respiratory compromise (eg, dyspnea, wheeze-bronchospasm, stridor, reduced PEF, 
and hypoxemia)
c.
reduced blood pressure or associated symptoms (eg, hypotonia [collapse], syncope, 
and 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 center 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, Set A or B, and indication that they are pharmacokinetic samples. Samples will 
be stored at a temperature of –70°C to -20°C (inclusive) in an upright position until they are 
shipped to the central laboratory.
Shipment and Analysis of Samples
Serum or 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 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, for approximately 10 minutes, at 2 C 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, polypropylene tubes (Sets A and B).
Label of samples should include study number, patient randomization number, nominal 
collection time, Set A or B, and indication that they are antidrug antibody (ADA) samples. 
Serum samples will be stored at a temperature of -70 ºC to -20°C 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 
sample analysis will be determined by the sponsor’s representatives of bioanalytical departments

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 investigational medicinal product (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)

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
204

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 7.1.5.3, 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 
the equivalent, before they are transcribed to the case report form (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, Independent Ethics Committee/Institutional 
Review Board (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, and 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 clinical data management system (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, and site 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 standard operating procedures (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, and electronic diary)

safety reports

financial disclosure reports/forms

reports of receipt, use, and disposition of the investigational medicinal products

copies of all correspondence with sponsor, the IEC/IRB, and any competent authority

Uncontrolled Study–Cluster Headache
Clinical Study Protocol with Amendment 04
Study TV48125-CNS-30058
207
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 contract 
research organization 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.
