Protocol Summary
Study Compound(s):  Ubrogepant
Phase:  3
Study Objective:  To evaluate the efficacy, safety, and tolerability of 2 doses of ubrogepant (25 mg and 50 mg) 
compared to placebo for the acute treatment of a single migraine attack
Clinical Hypotheses:
1.  At least 1 ubrogepant dose is superior to placebo in the acute treatment of migraine.
2.  Ubrogepant is safe and tolerable.
Study Design
Structure:  Multicenter, randomized, double-blind, placebo-controlled, parallel-group, single attack study; 
randomization to placebo, ubrogepant 25 mg, or ubrogepant 50 mg.
Duration:  The study includes a screening period of up to 14 days prior to randomization, a 60-day period in 
which to treat a single migraine attack, and a 4-week follow-up period.
Study Treatment Groups:  Ubrogepant 25 mg, ubrogepant 50 mg
Controls:  Ubrogepant placebo
Dosage/Dose Regimen:  Study participants will have up to 60 days to treat a single qualifying migraine attack of 
moderate or severe headache pain intensity at home. Patients have the option to take a second dose of 
investigational product (IP) or rescue medication if the patient has either a nonresponding migraine or a 
migraine recurrence. 
 
  
 
 
 
 
 
 
Study Population Characteristics
Number of Patients:  Approximately 1650 patients will be randomized (550 per treatment arm)
Condition/Disease:  Migraine with or without aura
Key Inclusion Criteria:  To be eligible for study participation, patients must be 18 to 75 years of age (inclusive), 
have a history of migraine with or without aura for at least 1 year consistent with a diagnosis according to the 
International Classification of Headache Disorders criteria, 3rd edition, beta version (ICHD-3 beta, 2013) and

Response Measures
Efficacy:  Rating of headache severity, absence or presence of migraine-associated symptoms, use of rescue 
medication, use of optional second dose, and recurrence of headache pain
 
 
 
 
 
General Statistical Methods and Types of Analyses:  The efficacy analyses will be based on the Modified 
Intent-to-treat (mITT) Population. The last observation carried forward (LOCF) approach will be used to impute 
missing posttreatment values. Baseline for efficacy is defined as the last nonmissing efficacy assessment before 
the initial dose of study treatment. For each primary variable, the observed response proportions will be 
provided by treatment group. The primary efficacy variable of pain freedom at 2 hours after the initial dose will 
be analyzed using a logistic regression model with categorical terms for treatment group, historical triptan 
response (triptan responder, triptan insufficient responder, or triptan naïve), use of medication for migraine 
prevention (yes/no), and baseline headache severity (moderate or severe). The primary efficacy variable of 
absence of the most bothersome symptom at 2 hours after the initial dose will be analyzed using a similar 
logistic regression model with an additional categorical term for the underlying symptom that was identified as 
the most bothersome. The respective comparisons of the ubrogepant doses versus placebo, which are the formal 
tests of the efficacy hypotheses, will be conducted using the appropriate pairwise contrasts within the logistic 
regression model. For secondary and other efficacy endpoints related to migraine headache pain severity and/or 
recurrence, migraine-associated symptoms, or use of rescue medication (including the second dose of IP), the 
observed response proportions will be analyzed using the same methods used to analyze the primary efficacy 
variables. For secondary efficacy endpoints on migraine-associated symptoms, baseline presence/absence of the 
symptom will be included as an additional covariate for the logistic regression model. The proportion of 
patients reporting satisfaction with study medication at 2 and 24 hours after the initial dose, the proportion of 
patients able to function normally at 1, 2, 4, and 8 hours after the initial dose, and the proportion of patients 
assessed by the PGIC as “much better” or “very much better” at 2 hours after the initial dose will be analyzed 
using the same methods used to analyze the primary efficacy variables. The baseline functional disability score 
will also be included as a covariate for the analysis of the proportion of patients able to function normally. For 
the change from baseline in EQ-5D-5L index value at 24 hours after the initial dose, treatment comparisons of 
ubrogepant dose groups versus placebo will be performed using an analysis of covariance (ANCOVA) model 
with categorical terms for treatment group, baseline severity, historical triptan response, and use of medication 
for migraine prevention, and with the baseline EQ-5D-5L index value as a covariate. Descriptive statistics will 
be provided for the change from baseline in the EQ VAS score at 24 hours after the initial dose by treatment 
group.

Background and Clinical Rationale
What is Migraine and How Prevalent is It?
Migraine affects 18% of women and 6% of men in the United States with a peak prevalence 
occurring between the ages of 25 to 55 years. Approximately one-third of migraineurs have 
3 or more migraine headaches per month, and over half report severe impairment or the need 
for bed rest during an attack (Lipton et al, 2007). In the United States , work loss due to 
migraine is estimated to cost ~ $13 billion annually (Hu et al, 1999). Prevalence is similar in 
Europe, with migraine headache affecting 17.6% of women and 8% of men 
(Stovner and Andree, 2010). It is currently ranked by the World Health Organization as 19th 
among causes of disability (Katsarava et al, 2012). 
Migraine is typically characterized by attacks of throbbing, unilateral headache of moderate 
or severe pain intensity, associated with nausea, vomiting, and/or sensitivity to light 
(photophobia) and sound (phonophobia). In about 25% of individuals, migraine headache 
may be preceded by focal neurological dysfunction (aura). Improving the diagnosis and 
optimizing treatments for migraine have been recognized as critically important to reduce the 
global burden of migraine (Katsarava et al, 2012).
Because there are no biological markers for migraine, diagnosis is based on clinical history, 
exam, and the exclusion of other headache disorders. Physicians apply clinical criteria to 
guide diagnoses and subsequent treatment. Episodic migraine is a syndrome diagnosis 
applied to patients with migraine (with or without aura) who have 1 to 14 headache days per 
month. Chronic migraine is a specific International Classification of Headache Disorders 
criteria, 3rd edition beta version (ICHD-3 beta) diagnosis applied to a subset of patients with 
≥15 headache days per month (ICHD-3 beta, 2013; Katsarava et al, 2012; 
Olesen et al, 2006). 
What is CGRP and What is its Relationship to Migraine?
CGRP (calcitonin gene-related peptide) is a neuropeptide implicated in the pathophysiology 
of migraine. CGRP levels in the cranial venous outflow (ie, external jugular vein) are
increased during a migraine attack (Goadsby and Edvinsson, 1993) and exogenously
administered CGRP has been shown to trigger migraine-like headache in migraineurs. The 
majority (80% to 90%) of trigeminal Aδ fibers that innervate the dura contain CGRP,
suggesting that these fibers may be involved in sterile neurogenic inflammation and
migraine pain transmission. Furthermore, the CGRP receptor is present on human meningeal
and cerebral blood vessels. These observations suggest that activation of the 
UBR-MD-02
15


Allergan Confidential
Protocol UBR-MD-02 Amendment 3
16
trigeminovascular system, with release of CGRP, may play a key role in migraine 
pathogenesis and that inhibition of CGRP function may yield a novel therapeutic approach to
treating migraine.
Establishment of CGRP Antagonism to Treat Migraine
The ability of CGRP antagonism to relieve pain in the acute treatment of migraine was
established by using an intravenous (IV) formulation of olcegepant (Olesen et al, 2004), 
and replicated by Merck & Co., Inc with an oral formulation of telcagepant, a highly
selective CGRP receptor antagonist (CGRP RA). In Phase 3 studies, telcagepant was
superior to placebo in the primary endpoints of 2-hour pain freedom, 2-hour pain relief, 
and the absence of associated symptoms (photophobia, phonophobia, and nausea), as well as
the key secondary endpoint of 24-hour sustained pain freedom (Connor et al, 2009). 
Serum alanine aminotransferase (ALT) increases were observed with telcagepant as well as 
with a second CGRP antagonist, MK-3207. For this reason, the development of these 
compounds was stopped. 
What is Ubrogepant?
Ubrogepant, a novel CGRP receptor antagonist that is chemically distinct from both 
telcagepant and MK-3207, is now being developed for the acute treatment of migraine. 
Preclinical and clinical studies conducted to date for ubrogepant have shown no evidence of 
hepatotoxicity.
A Phase 2b clinical study was conducted, which compared 1-, 10-, 25-, 50-, and 100-mg 
doses of ubrogepant to placebo in the acute treatment of migraine. Overall, all the ubrogepant 
doses tested were well tolerated and the adverse event (AE) profile of all ubrogepant doses 
did not differ significantly from placebo. For the primary efficacy endpoint of pain freedom
at 2 hours, ubrogepant doses of 1 and 10 mg did not differ from placebo, but doses of 25, 50, 
and 100 mg were better than placebo. For the primary efficacy endpoint of pain relief at 
2 hours none of the ubrogepant doses differed from placebo, probably due to a high placebo 
response rate.
The absence of migraine-associated symptoms of photophobia, phonophobia, and nausea was
assessed as key secondary endpoints. Ubrogepant doses of 50 and 100 mg were significantly 
better than placebo for absence of phonophobia and photophobia at 2 hours, whereas 25 mg 
did not differ from placebo. None of the ubrogepant doses differed from placebo for the 
endpoint of absence of nausea at 2 hours. Measures of sustained migraine headache relief 
UBR-MD-02
16


Allergan Confidential
Protocol UBR-MD-02 Amendment 3
17
(2 to 24 hours and 2 to 48 hours sustained pain freedom and sustained pain relief) generally 
suggested that ubrogepant 50 mg and 100 mg were more effective than the 25-mg dose.
The purpose of this study will be to assess the safety and efficacy of 2 doses of ubrogepant, 
25 and 50 mg, versus placebo in the acute treatment of migraine with or without aura, in a 
randomized, double-blind, placebo-controlled Phase 3 study.

Study Objectives and Clinical Hypotheses 
2.1
Study Objectives
To evaluate the efficacy, safety, and tolerability of 2 doses of ubrogepant (25 and 50 mg) 
compared to placebo for the acute treatment of a single migraine attack.
2.2
Clinical Hypotheses
1. At least 1 ubrogepant dose is superior to placebo in the acute treatment of migraine.
2. Ubrogepant is safe and tolerable.
3.
Study Design
This multicenter, randomized, double-blind, placebo-controlled, parallel-group, single attack 
study will enroll approximately 1650 patients from approximately 100 centers in the United 
States. Patients will be randomized (1:1:1) to 1 of the following 3 treatment groups:  placebo, 
ubrogepant 25 mg, or ubrogepant 50 mg.
Study participants will have up to 60 days to treat a single qualifying migraine attack of 
moderate or severe intensity at home. Patients unable to treat a qualifying migraine within 
this time will be discontinued from the study.
 
 
 
 
 
 
The planned efficacy assessments are rating of headache severity, absence or presence of 
migraine-associated symptoms, use of rescue medication, use of optional second dose, and 
UBR-MD-02

Protocol UBR-MD-02 Amendment 3
18
recurrence of headache pain. A list and description of each efficacy assessment is in 
Section 6.1 and the efficacy analyses are presented in Section 7.3.1.
The planned safety assessments are AEs, clinical laboratory tests, electrocardiograms 
(ECGs), vital signs, physical examination, and the Columbia-Suicide Severity Rating Scale 
(C-SSRS). Details regarding safety assessments are described in Section 6.5 and the safety 
analyses are presented in Section 7.3.3.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
3.1
Adjudication Committee and Data Safety Monitoring Board
An Adjudication Charter will be established and will describe the process for the blinded 
surveillance, monitoring, and adjudication by the Clinical Adjudication Committee of events 
of posttreatment elevations of ALT and/or aspartate aminotransferase (AST) ≥3 times the 
upper limit of normal (ULN) in the ubrogepant program. The purpose of this committee 
charter will be to provide a standardized process for the adjudication of data associated with 
these events in order to determine whether the elevation was related to ubrogepant.

Summary of Methods of Data Collection
An IWRS will be used to randomize patients and manage IP inventory. Data for this study 
will be collected using eCRFs via an electronic data capture system, eDiaries, and eTablets. 
Source documents will be used at the sites and may include a patient’s medical record, 
hospital charts, clinic charts, the investigator’s patient study files, as well as the results of 
diagnostic tests such as laboratory tests, ECGs, etc. Centralized vendors will be used for the 
analysis of all blood/urine samples and ECG assessments. Additional information on the 
collection and handling of samples is detailed in the respective laboratory manuals.
Patients will use an eDiary to record details associated with their migraine attack, including, 
but not limited to the date and time of dosing, efficacy assessments (eg, pain severity, 
absence or presence of migraine-associated symptoms), and other important study 
information at designated timepoints post-dose. Training for the eDiary will be provided for 
qualified patients during the Randomization Visit (Visit 2). For details regarding eDiary 
instructions to patients, see the eDiary manual.
The C-SSRS will be conducted as a clinical interview at each visit and recorded by qualified

Primary Efficacy Variables
The coprimary efficacy parameters for the United States are as follows:  

Pain freedom (PF) at 2 hours after the initial dose, defined as a reduction in headache 
severity from moderate/severe at baseline to no pain, at 2 hours after the initial dose

Absence of the most bothersome migraine-associated symptom (the most bothersome 
migraine-associated symptom will be identified at baseline for each patient) at 2 hours 
after the initial dose. 
7.2.2
Secondary Efficacy Variables
The secondary efficacy parameters for the United States are:

Pain relief (PR) at 2 hours after the initial dose, defined as the reduction of a 
moderate/severe migraine headache to a mild headache or to no headache, at 2 hours 
after the initial dose

Sustained pain relief (SPR) from 2 to 24 hours after the initial dose, defined as pain 
relief with no administration of either rescue medication or the second dose of IP, and 
with no occurrence thereafter of a moderate/severe headache during the relevant 
number of hours after dosing with the IP

Sustained pain freedom (SPF) from 2 to 24 hours after the initial dose, defined as pain 
freedom with no administration of either rescue medication or the second dose of IP, 
and with no occurrence thereafter of a mild/moderate/severe headache during the 
relevant number of hours after dosing with the IP

efficacy is defined as the last nonmissing efficacy assessment before the initial dose of study 
treatment. All statistical tests will be 2-sided hypothesis tests performed at the 5% level of 
significance for main effects. All confidence intervals will be 2-sided 95% confidence 
intervals, unless stated otherwise.

Efficacy Analyses
7.3.1.1
Primary Efficacy Analyses
For each primary variable, the observed response proportions will be provided by treatment 
group. The primary efficacy variable of pain freedom at 2 hours after the initial dose will be 
analyzed using a logistic regression model with categorical terms for treatment group, 
historical triptan response (triptan responder, triptan insufficient responder, or triptan naïve), 
use of medication for migraine prevention (yes/no), and baseline headache severity 
(moderate or severe). The primary efficacy variable of absence of the most bothersome 
symptom at 2 hours after the initial dose will be analyzed using a similar logistic regression 
model with an additional categorical term for the underlying symptom that was identified as 
the most bothersome. If the logistic regression model fails to converge due to complete or 
quasi-complete separation, Firth’s penalized likelihood method (Firth, 1993) will be used. 
The logistic regression model will be referred to as the primary model. 
The respective comparisons of the ubrogepant doses versus placebo, which are the formal 
tests of the efficacy hypotheses, will be conducted using the appropriate pairwise contrasts 
within the logistic regression model. Treatment comparisons will be based on the model-
derived odds ratios and their associated 95% confidence intervals. Two-sided p-values will 
also be provided. 
, the study will be considered a success if at least 1 ubrogepant dose is 
demonstrated to be superior to placebo on both coprimary variables after multiplicity 
adjustment. 
 
 
7.3.1.2
Secondary Efficacy Analyses 
For each secondary efficacy endpoint, the observed response proportions will be analyzed 
using the same methods used to analyze the primary efficacy variables. The respective 
comparisons of the ubrogepant doses versus placebo will be conducted using model-derived 
odds ratios, 95% confidence intervals and p-values from the logistic regression model. For 
secondary efficacy endpoints on migraine-associated symptoms, baseline presence/absence 
of the symptom will be included as an additional covariate for the logistic regression model. 
UBR-MD-02

Allergan Confidential
Protocol UBR-MD-02 Amendment 3
43
A graphical approach by Bretz et al (2009) will be used to control the overall type I error rate 
for multiple comparisons across the ubrogepant doses and the primary and secondary 
efficacy endpoints. The coprimary efficacy endpoints will serve as the gatekeepers of the 
secondary endpoints. The secondary endpoints will be tested in the same order as they appear 
in the list of secondary endpoints, except for the 3 migraine-associated symptoms which will 
be treated at the same level to allow the recycling of weights among the 3 symptom 
endpoints. Recycling of weights between the 2 doses is also allowed. The details of the 
multiple comparison procedure will be provided in the statistical analysis plan (SAP).

indicate “not done”.
8.7
Compliance with Protocol
All assessments will be conducted at the appropriate visits as outlined in Table 1, and the
timing of the visits should occur as close as possible to the specified day. At each visit, the 
patient will be asked if the patient changed the dose/regimen of any existing concomitant 
UBR-MD-02
58


Allergan Confidential
Protocol UBR-MD-02 Amendment 3
59
medications or initiated the use of any new concomitant medications since the last visit to 
ensure compliance with the protocol. 
Patients will record the requested information regarding their migraine attack and the IP 
taken in the eDiary. IP compliance will be closely monitored by counting the number of 
tablets dispensed and returned. Every effort will be made to collect all unused IP.
8.8
Early Discontinuation of Patients
A premature discontinuation will occur when a patient who signed the informed consent form 
(ICF) and has been randomized ceases participation in the study, regardless of circumstances, 
before completion of the study. Patients can be prematurely discontinued from the study for 
one of the following reasons:

AE

Protocol violation

Noncompliance with IP

Withdrawal of consent (a clear reason must be documented)

Lost to follow-up. (Every effort must be made to contact the patient; a 
certified/traceable letter must be sent.)

Lack of Qualifying Event (a qualifying migraine is not treated within 60 days from 
Randomization [Visit 2])

Pregnancy

Other reasons
Patients may voluntarily withdraw from the study at any time. Notification of early patient 
discontinuation from the study and the reason for discontinuation will be clearly documented 
on the appropriate electronic case report form (eCRF). All randomized patients who 
prematurely discontinue from the study, regardless of cause, should be seen for a final 
assessment. A final assessment will be defined as completion of the evaluations scheduled for 
Visit 3/Early Termination
 
. If 
the patient discontinues after IP is taken, the patient is also expected to return for the Safety 
Follow-up Visit (Visit 4) 4 weeks postdose.

8.9
Withdrawal Criteria
Women who become pregnant will be withdrawn from the study (see Section 4.5.1.2) and 
should refrain from taking IP. The patient should return to the clinic for early termination
procedures (Visit 3), including the safety follow-up visit (Visit 4) if IP was taken.
Patients who reply with “yes” to questions 4 or 5 in the suicidal ideation section or “yes” to 
any question in the suicidal behavior section of the C-SSRS at Visit 3 
 
 and should receive appropriate follow-up as in routine clinical practice, 
including the safety follow-up visit (Visit 4) if IP was taken.
A patient with a condition and/or a situation that, in the investigator's opinion, may put the 
patient at significant risk, may confound the study results, or may interfere significantly with 
the patient's participation in the study may be withdrawn from treatment.
 
 
 
 
 
8.11
Study Termination
Allergan may stop the study (and/or the study site) for any reason with appropriate 
notification.
9.
Adverse Events
Adverse events occurring during the study will be recorded on an AE eCRF. If AEs occur, the 
first concern will be the safety of the study participants.
9.1
Definitions
9.1.1
Adverse Event
An AE is any untoward medical occurrence in a patient or clinical investigation patient 
administered a pharmaceutical product and that does not necessarily have a causal 
relationship with this treatment. An AE can therefore be any unfavorable and unintended sign 
(including an abnormal laboratory finding), symptom, or disease temporally associated with 
UBR-MD-02
60


Allergan Confidential
Protocol UBR-MD-02 Amendment 3
61
the use of a medicinal (investigational) product, whether or not related to the medicinal 
(investigational) product. In addition, during the screening period, AEs will be assessed 
regardless of the administration of a pharmaceutical product.
Note:  AEs must be collected once informed consent has been obtained, regardless of 
whether or not the patient has been administered study drug.
Progression of treatment indication including new or worsening of anticipated clinical signs 
or symptoms, which are collected as clinical efficacy variables and assessed as unequivocally 
associated with the disease progression and /or lack of efficacy, should NOT be reported as 
AEs unless the disease progression is greater than anticipated in the natural course of the 
disease. 
Adverse events will be assessed, documented, and recorded in the eCRF throughout the study 
(ie, after informed consent has been obtained). At each visit, the investigator will begin by 
querying for AEs by asking each patient a general, non-directed question such as “How have 
you been feeling since the last visit?” Directed questioning and examination will then be 
done as appropriate. All reported AEs will be documented on the appropriate eCRF.
9.1.2
Serious Adverse Event
An SAEis any AE occurring at any dose that results in any of the following outcomes:  death, 
a life-threatening adverse event, inpatient hospitalization or prolongation of existing 
hospitalization, a persistent or significant disability/incapacity, or a congenital anomaly/birth 
defect. Important medical events that may not result in death, be life-threatening, or require 
hospitalization may be considered an SAEwhen, based upon appropriate medical judgment, 
they may jeopardize the patient and may require medical or surgical intervention to prevent 
one of the outcomes listed in this definition. (See Section 9.3 for procedures for reporting 
SAEs.)
Allergan considers all cancer AEs as SAEs. In addition, Allergan considers any abortion 
(spontaneous or nonspontaneous) as an SAE.
Preplanned surgeries or procedures for pre-existing, known medical conditions for which a 
patient requires hospitalization is not reportable as an SAE.
Any preplanned surgery or procedure should be clearly documented in the site source 
documents by the medically qualified investigator at the time of the patient’s entry into the 
study. If it has not been documented at the time of the patient’s entry into the study, then it 
should be documented as an SAE and reported to Allergan.
UBR-MD-02
61


Allergan Confidential
Protocol UBR-MD-02 Amendment 3
62
9.1.3
Severity
A clinical determination will be made of the intensity of an adverse event. The severity 
assessment for a clinical AE must be completed using the following definitions as guidelines:
Mild
Awareness of sign or symptom, but easily tolerated
Moderate
Discomfort enough to cause interference with usual activity
Severe
Incapacitating with inability to work or do usual activity
9.1.4
Relationship to Study Drug or Study Procedure
A determination will be made of the relationship (if any) between an AE and the study drug 
or study procedure, as applicable. A causal relationship is present if a determination is made 
that there is a reasonable possibility that the AE may have been caused by the drug or study 
procedure.
9.2
Procedures for Reporting Adverse Events
Any AE must be recorded on the appropriate eCRF.
All SAEs that are drug-related and unexpected (not listed as treatment-related in the current 
investigator's brochure) must be reported to the governing Institutional Review 
Board/Independent Ethics Committee (IRB/IEC) as required by the IRB/IEC, local 
regulations, and the governing health authorities. Any adverse event that is marked 
“ongoing” at the exit visit must be followed-up as appropriate.
9.3
Procedures for Reporting a Serious Adverse Event
Any SAE occurring during the study period (beginning with informed consent) and for at 
least 30 days after the last dose of study drug must be immediately reported but no later than 
24 hours after learning of an SAE. Serious adverse events must be reported to Allergan or 
Agent of Allergan (eg, contract research organization [CRO]) and recorded on the SAE form. 
All patients with an SAE must be followed up and the outcomes reported. The investigator 
must supply Allergan and the IRB/IEC with any additional requested information (eg, 
autopsy reports and discharge summaries).
In the event of an SAE, the investigator must:
UBR-MD-02
62


Allergan Confidential
Protocol UBR-MD-02 Amendment 3
63
1. Notify Allergan immediately by fax or email using the SAE form (contact details can 
be found on page 1 of the SAE form); phone numbers and relevant Allergan 
personnel contacts are also on the front page of protocol.
2. Obtain and maintain in his/her files all pertinent medical records, information, and 
medical judgments from colleagues who assisted in the treatment and follow-up of 
the patient.
3. Provide Allergan with a complete, written description of the AE(s) on the SAEform 
describing the event chronologically, including any treatment given (eg, medications 
administered, procedures performed) for the AE(s). Summarize relevant clinical 
information about the event:  signs, symptoms, diagnosis, clinical course and relevant 
clinical laboratory tests, etc. Include any additional or alternative explanation(s) for 
the causality which includes a statement as to whether the event was or was not 
related to the use of the investigational drug.
4. Promptly inform the governing IRB/IEC of the SAEas required by the IRB/IEC, local 
regulations, and the governing health authorities.
9.4
Exposure to Investigational Product during Pregnancy
Study center personnel must report every pregnancy from the time he or she signs the ICF for 
the trial until 30 days after the last dose of IP on the Pregnancy Form as soon as possible 
(within 24 hours of learning of the pregnancy to the SAE/Pregnancy fax number, 
even if no AE has occurred. Pregnancies in female partners of male patients 
must also be reported. The pregnancy must be followed to term and the outcome reported by 
completing a follow-up Pregnancy Form. If, however, the pregnancy is associated with a 
SAE (eg, if the mother is hospitalized for hemorrhage), in addition to the Pregnancy Form, a 
separate SAE Form must be filed as described in Section 9.3 with the appropriate serious 
criterion (eg, hospitalization) indicated.

9.7
Procedures for Unmasking of Investigational Product
When necessary for the safety and proper treatment of the patient, the investigator can 
unmask the patient’s treatment assignment to determine which treatment has been assigned 
and institute appropriate follow-up care. When possible, the Allergan Medical Monitor
should be notified prior to unmasking IP. The investigator should inform the Allergan 
Medical Monitor of the unmasking if there is no notification prior to the unmasking.
UBR-MD-02

Protocol Summary –
General Statistical 
Methods and Types of 
Analyses
Revised to note that PGIC will be 
completed 2 hours after the initial dose: 
…the proportion of patients assessed by 
the PGIC as “much better” or “very much 
better” at 2 24hours after the initial dose 
will be analyzed using the same methods 
used to analyze the primary efficacy 
variables.
Expert input recommended a change in 
PGIC assessment from 24 hours to 2 
hours after the initial dose to increase 
the probability of differentiating 
between treatment and placebo

Protocol Summary,

Efficacy Analyses
Revised logistic regression model as follows:
For each primary variable, the observed 
response proportions will be provided by 
treatment group. The primary efficacy variable 
of pain freedom at 2 hours after the initial dose 
will be analyzed using a logistic regression 
model with categorical terms for treatment 
group, historical triptan response (triptan 
responder, triptan insufficient responder, or 
triptan naïve), use of medication for migraine 
prevention (yes/no), and baseline headache 
severity (moderate or severe). The primary 
efficacy variable of absence of the most 
bothersome symptom at 2 hours after the initial 
dose will be analyzed using a similar logistic 
regression model with an additional categorical 
term for the underlying symptom that was 
identified as the most bothersome. 
The treatment response on the 
most bothersome symptom 
varies according to which 
symptom is identified as the 
most bothersome
Protocol Summary, 
Section 7.3.1.2 Secondary 
Efficacy Analyses
Revised logistic regression model to include:
For secondary efficacy endpoints on migraine-
associated symptoms, baseline presence/absence 
of the symptom will be included as an additional 
covariate for the logistic regression model.
The treatment response on 
migraine-associated symptoms 
is different depending on 
whether the patient had the 
symptom at predose baseline

3. Data Handling and Analysis Conventions
4.1
Study Design Summary
Structure:  Multicenter, randomized, double-blind, placebo-controlled, parallel-group, single 
attack study; randomization to placebo, ubrogepant 25 mg, or ubrogepant 50 mg.
Duration:  The study includes a screening period of up to 14 days prior to randomization, a 
60-day period in which to treat a single migraine attack, and a 4-week follow-up period.
Study Treatment Groups:  Ubrogepant 25 mg, ubrogepant 50 mg
Controls:  Ubrogepant placebo
Dosage/Dose Regimen:  Study participants will have up to 60 days to treat a single qualifying 
migraine attack of moderate or severe headache pain intensity at home. Participants have the 
option to take a second dose of investigational product (IP) or rescue medication if the 
participant has either a nonresponding migraine or a migraine recurrence. Participants who are 
randomized to ubrogepant arms will be randomly assigned at the Randomization Visit (Visit 2) to 
active treatment or placebo (1:1) for the blinded optional second dose. Participants randomized 
to the placebo arm will receive placebo for their blinded optional second dose.
Randomization/
  Participants will be randomized (1:1:1) to 1 of the following 
3 treatment groups:  placebo, ubrogepant 25 mg, or ubrogepant 50 mg. 
 
 
 
 
 
 
 
 
Number of Participants:  Approximately 1650 participants will be randomized (550 per 
treatment arm).

Methodology
Description
Note: Historical triptan response and use of medication for migraine 
prevention are stratification factors for the study. 
For the analysis of individual migraine-associated symptoms, baseline 
presence/absence of the symptom will be included as an additional covariate 
in the logistic regression model.
 
 
 
 
 
 
o
If the logistic regression model fails to converge due to complete or quasi-
complete separation, Firth’s penalized likelihood method (Firth, 1993) will be 
used. The profile penalized likelihood approach (Heinze and Schemper, 2002) 
will be used to make valid inference.

Formal test of efficacy hypothesis comparing 2 active treatments vs Placebo conducted 
using pairwise contrasts based on odds ratios and their 95% confidence intervals of the 
odds ratio

and summarized as follows:

Missing Data Handling by Endpoint Type
Parameter type
Timing
Missing Data Handling
 
Responder
Treatment Period

If missing headache severity, migraine-associated symptoms, 
satisfaction with study medication, or functional disability 
scale at scheduled postdose time points, use LOCF

Sensitivity analysis for the primary efficacy endpoints is to 
impute participants with missing data at 2 hours as non-
responders, provided that the participant has at least 1 
postdose value before 2 hours after the initial dose
 
 
 
A conservative approach will used to resolve the incompatibility between the answers to the 
headache recurrence questions at the 24- and 48-hour time points by setting the answer to the 
recurrence question at the 48-hour time point the same as the answer to the recurrence 
question at the 24-hour time point, when the 24-hour time point recurrence question indicates 
headache recurrence between 2 and 24 hours but the 48-hour time point recurrence question 
indicates either no or a less severe headache recurrence between 2 and 48 hours.

For sustained efficacy endpoints (sustained pain freedom and sustained pain relief from 2 to 24 
and 48 hours after the initial dose), the primary analysis will only include participants for whom 
the sustained efficacy endpoint in question can be determined based on all available data on 
headache severity, headache recurrence, use of rescue medication, and use of optional second 
dose. Figure 5-5 to Figure 5-8 show the diagrams for determining the sustained efficacy 
endpoints based on all available data.

A summary of the number and percentage of participants who took both the optional second dose 
and rescue medication within 24 (48) hours after the initial dose will also be provided by 
treatment sequence (placebo/placebo, ubrogepant 25 mg/25 mg, ubrogepant 25 mg/placebo, 
ubrogepant 50 mg/50 mg, ubrogepant 50 mg/placebo). The denominator is the number of
participants who took the optional second dose.
5.1.1.3.4
Multiple Comparisons Procedure for Primary and Secondary 
Endpoints
The overall familywise error rate (FWER) will be controlled at α = 0.05 for the set of primary 
and secondary endpoint comparisons between each dose level of ubrogepant vs. placebo both for 
the US analyses and for the EU analyses. 
A graphical approach by Bretz et al (2009) will be used to control the overall type I error rate for 
multiple comparisons across the ubrogepant doses and the primary and secondary efficacy 
endpoints. For the US analyses, the coprimary efficacy endpoints will serve as the gatekeepers of 
the secondary endpoints. 
 
. The secondary endpoints will be tested in the same 
order as they appear in the list of secondary endpoints, except for the 2 migraine-associated 
symptoms, photophobia and phonophobia, which will be treated at the same level to allow the 
recycling of weights among the 2 symptom endpoints. Recycling of weights between the 2 doses 
from nausea to pain freedom is also allowed.
Using graphical approach with the weighted Bonferroni-based closed test procedure, the 
endpoints are represented by circles with associated weights inside the circle. The weight is the 
fraction of α, representing local significance levels. The fraction in the rectangle, associated with 
a line connecting two circles, indicates the fraction of the local significance level of the circle at 
the beginning of the line which is added to the local significance level of the circle at the end of 
the line, if the null hypothesis at the beginning circle is rejected.

Subgroup Analyses
The following subgroup analyses will be conducted by historical triptan response. PF and 
absence of the most bothersome migraine-associated symptom at 2 hours after initial dose will 
be analyzed using similar models as the primary endpoints with the additional treatment group 
by historical triptan response interaction. Time to PF and absence of the most bothersome 
migraine-associated symptom within 2 hours after the initial dose will be analyzed by 
historical triptan response separately. 

PF at 2 hours after initial dose

Absence of the most bothersome migraine-associated symptom at 2 hours after initial 
dose (US only)

Time to PF within 48 hours after the initial dose 

Time to absence of the most bothersome migraine-associated symptom within 48 hours 
after the initial dose (US only)
A pooled analysis among triptan insufficient responders across ubrogepant pivotal studies will be 
conducted to demonstrate statistically significant efficacy in the triptan insufficient responders’ 
population.

1.5.3 Section 5.1.1.1.4, Missing Data (Pages 21-31)
Rationale: This section has been amended to update the missing data handling of sustained 
efficacy endpoints. 
The missing data section now reads as follows:
General missing data handling conventions are specified for methodologies in Section 
5.1.1.1.3 and summarized as follows:
Table 5-3
Missing Data Handling by Endpoint Type
Parameter type
Timing
Missing Data Handling
 
Responder
Treatment 
Period

If missing headache severity, migraine-associated symptoms, 
satisfaction with study medication, or functional disability 
scale at scheduled postdose time points, use LOCF

Sensitivity analysis for the primary efficacy endpoints is to 
impute participants with missing data at 2 hours as 
non-responders, provided that the participant has at least 1 
postdose value before 2 hours after the initial dose
 
 
 
 
 
 
 
 
A conservative approach will used to resolve the incompatibility between the answers to the 
headache recurrence questions at the 24- and 48-hour time points by setting the answer to the 
recurrence question at the 48-hour time point the same as the answer to the recurrence 
question at the 24-hour time point, when the 24-hour time point recurrence question indicates 
headache recurrence between 2 and 24 hours but the 48-hour time point recurrence question 
indicates either no or a less severe headache recurrence between 2 and 48 hours.

1.5.5 Section 5.1.1.3.4 Multiple Comparisons Procedure for Primary and 
Secondary Endpoints (Pages 46-48)
Rationale: This section has been modified to enhance the robustness of the testing procedure 
for efficacy at the ubrogepant 50 mg dose, in order to better reflect the relative clinical 
importance and likelihood of demonstration of effect for each endpoint.
The section now reads as follows:
A graphical approach by Bretz et al (2009) will be used to control the overall type I error rate 
for multiple comparisons across the ubrogepant doses and the primary and secondary efficacy 
endpoints. For the US analyses, the coprimary efficacy endpoints will serve as the 
gatekeepers of the secondary endpoints. 
 
. The secondary endpoints 
will be tested in the same order as they appear in the list of secondary endpoints, except for 
the 2 3 migraine-associated symptoms, photophobia and phonophobia, which will be treated 
at the same level to allow the recycling of weights among the 2 3 symptom endpoints. 
Recycling of weights between the 2 doses from nausea to pain freedom is also allowed.

1.5.6 Section 5.1.1.4.1 Study Treatment Exposure and Compliance
(Page 48)
Rationale: This section has been amended to add the summary of treatment exposure.
This section now reads as follows:
Study treatment exposure will be summarized and listed for the Safety Population. 
The summary of treatment exposure will include the number and percentage of participants 
who took the initial dose only, the number and percentage of participants who took both the 
initial dose and the optional second dose, and the number and percentage of participants who 
took the PK dose for each treatment group. 
The listing of treatment exposure will indicate whether the participant took the optional 
second dose and
 in addition to the first dose. 
Treatment compliance to the first dose of study medication will not be calculated as 
participants are only to take 1 tablet.

1.5.10Section 5.1.1.5 Subgroup Analyses
The section now reads as follows:
The following subgroup analyses will be conducted by historical triptan response. PF and 
absence of the most bothersome migraine-associated symptom at 2 hours after initial dose 
will be analyzed using similar models as the primary endpoints with the additional treatment 
group by historical triptan response interaction. Time to PF and absence of the most 
bothersome migraine-associated symptom within 2 hours after the initial dose will be 
analyzed by historical triptan response separately.
