
The primary efficacy measure is the investigator’s assessments of GL at maximum frown 
using the FWS.

Participants will undergo a Screening Visit up to 30 days before randomization on Day 1. 
All screening data must be available to the investigator prior to randomization on Day 1.

On Day 1, participants will be randomly assigned in a 3:1 ratio to receive AGN-151586 
or placebo. Enrollment stratification will be by baseline GL severity at maximum frown, 
assessed by the clinician (principal investigator or physician subinvestigator) using the
FWS. 

Study intervention on Day 1 will be administered as 5 injections in the glabellar complex 
(1 in the procerus and 2 in each corrugator).

Participants will remain in the clinic for the first 12 hours after administration of study 
intervention for serial assessments at Hours 4, 8 and 12. Thereafter, participants return to 
the clinic on Day 2 (Hour 24 and Hour 36), Day 3 (Hour 48 and Hour 60), Day 7, 
Day 14, Day 21, Day 28, Day 35, and Day 42.  

For each dose group, an internal data monitoring committee (DMC), independent from 
the study team, will review select safety and efficacy data from a subset of participants 
(n ≥16) with data through 14 days postintervention (in addition to cumulative data from 
the prior cohort[s]).

The DMC may recommend proceeding with the nominal dose for the next cohort, request 
additional data (eg, data from additional participants in the cohort, data from visits after 
Day 14), request to repeat the current dose or a lower dose, request an intermediate dose 
be evaluated (between the dose of the current cohort and the nominal dose for the next 
cohort), or request dose escalation be terminated.
Number of Participants:
Approximately 200 participants will be enrolled. Accounting for a dropout rate of 10%, it is 
anticipated that approximately 180 participants will complete the study. A total of up to 5 dose 
cohorts are planned with a randomization allocation of 3:1 for AGN-151586 (n = 30) and 
placebo (n = 10) for each cohort.
Number of Sites:
Approximately 10 US investigational sites

Introduction

Study Rationale
The purpose of this Phase 2b study is to evaluate the safety and efficacy of AGN-151586 over a 
range of doses for the treatment of moderate to severe GL.
2.2.
Background
Botulinum Neurotoxin Serotype E
The bacterium clostridium botulinum produces several distinct serotypes of botulinum 
neurotoxins designated A through G (Barash 2014; Keller 2006). These neurotoxins are some of 
the most potent molecules in nature, and all have the capability to block skeletal muscle 
contraction by blocking presynaptic acetylcholine release at the neuromuscular nerve junction.
Even though they have similar modes of action, each serotype has distinct properties that 
differentiate them from each other. 
Botulinum Neurotoxin Serotype E has been shown to inhibit muscle contraction by preventing 
the acetylcholine release at the neuromuscular junction. This effect has been shown in animals as 
well as humans (Adler 2001; Eleopra 1998). Epidemiologic studies in humans who have 
contracted botulism caused by BoNT/E have shown classic signs of systemic disease 
characterized by flaccid paralysis with earlier onset than classic botulism with BoNT/A 
(McLaughlin 2004).
In the published literature, BoNT/E has a distinct profile with a faster onset and shorter duration 
of effect compared with BoNT/A. Nonclinical studies have shown BoNT/E to have faster 
translocation in neurons (Keller 2004) and faster inhibition on neuromuscular transmission
(Wang 2008), suggesting its potential effect of faster onset of action in comparison with 
BoNT/A. A clinical trial in humans showed that participants recovered faster from paralysis after 
BoNT/E was injected into extensor digitorum brevis muscles, suggesting its duration of 
conferring paralytic effect might be shorter than BoNT/A (Eleopra 1998). 
Indication
Glabellar lines are deep furrows or frown lines in the glabellar area of the face and result from 
the repetitive functional action of the underlying mimetic facial musculature during animation 
(Blitzer 1993). The development of facial lines (such as GL) is an age-related change of the face 
that occurs because of the repetitive muscle contractions that are associated with common facial 
expressions. Thus, these facial lines can be observed with contraction (dynamic rhytides) or in 
more severe cases in repose (static rhytides). Increasing severity in the appearance of facial lines 
has been associated with a patient’s perception of reduced attractiveness and a negative effect on 
self-esteem and sense of well-being (Koblenzer 1996). Furthermore, the appearance of these 
facial lines can lead to a miscommunication of an emotional state of anger, anxiety, disapproval, 
or sadness (Khan 2001), causing distress and affecting social interactions (Finn 2003).

Evidence supports that unattractive or aging skin is indeed related to psychological and 
psychosocial impacts (Farage 2010). Psychological or psychosocial impacts can be characterized 
as changes in confidence, attractiveness, self-esteem, emotional burdensomeness, self-
perceptions of appearance or age, emotional distress, and state of bother. The evaluation of 
psychological or psychosocial impacts associated with aging facial skin should be assessed from 
patients’ perspectives since these impacts are dependent on their perceptions.
The popularity of BoNT/A cosmetic treatment of GL in adults is related to its proven efficacy for 
reducing moderate to severe facial lines (Beer 2006); well documented safety profile
(Brin 2009); and positive impact on psychological well-being and the resulting psychosocial 
benefits (Finn 2003).
When injected at therapeutic doses, it is expected that BoNT/E, like BoNT/A, produces partial 
chemical denervation of the muscle, resulting in localized reduction in muscle activity. Because 
GL result from muscular activity, the muscle relaxation leads to a temporary relief of facial lines. 
While it was previously thought that these facial lines were structural and permanent, the effects 
of these injections demonstrate the lines are part functional and may be associated with persistent 
increased muscle tone (Garcia 1996; Le Louarn 2007).
Based on published data for BoNT/E, in addition to preclinical and clinical experiences with 
AGN-151586, it is anticipated that at a clinically efficacious dose, AGN-151586 will exhibit a 
faster onset of improvement in GL severity compared with BoNT/A, with shorter duration of 
treatment effect.
AGN-151586
AGN-151586 (previously referred to as EB-001) is a BoNT/E and has been evaluated in clinical 
studies for various indications up to a total dose of 
U. These studies are briefly summarized 
below. For additional information and details, please refer to the IB.
The first-in-human study (EB001-GL201) determined that over a limited range of doses up to 
U, AGN-151586 was well tolerated when injected in the glabellar complex (procerus and 
bilateral corrugator muscles) and exhibited a trend of fast onset (within 24 hours) and a limited
duration of clinical effect (approximately 2 weeks) compared with the well characterized clinical 
profile of BoNT/A for the treatment of GL. 
In a Phase 2 exploratory study (EB001-SR201), a single dose of
U AGN-151586 was 
administered as 5 injections (divided equally) to the frontalis muscle during Mohs surgery in the 
forehead. The data suggested favorable safety and tolerability at the tested dose. During the 
wound healing and acute scar formation phase (up to Day 30), descriptive results of some of the 
exploratory analyses were consistent with the hypotheses that AGN-151586 may improve overall 
scar appearance, decrease itch and pain associated with the surgical wound, and improve the scar 
color and stiffness. However, it should be noted that only a single dose of AGN-151586 was 
evaluated, which may not have been sufficient to capture the optimal efficacy response for 
postsurgical scar reduction. 
The safety and efficacy of AGN-151586 injections in reducing postsurgical musculoskeletal pain 
in participants undergoing elective augmentation mammoplasty was evaluated in

Study EB001-MA201. Six doses of AGN-151586 (ranging from 
U) were 
evaluated. No dose response was observed, and there was no statistically significant difference in 
pain reduction between any dose group compared with placebo. This study showed favorable 
safety and tolerability.
The safety and efficacy of AGN-151586 in reducing musculoskeletal pain was also evaluated in 
Study EB001-ABD201 in participants undergoing elective abdominoplasty. This study evaluated
3 doses of AGN-151586 ranging from 
U. The study was terminated early as a 
result of a business decision. The available data suggested favorable safety and tolerability, but 
no efficacy conclusion could be drawn.
AGN-151586 has been evaluated in a series of pharmacology and nonclinical toxicology studies 
in mice, rats, and monkeys. In addition to faster onset and shorter duration of effect when 
compared with BoNT/A in these animal models, it is also less potent in terms of extent of muscle 
paralysis at peak efficacy. The magnitude of lower potency of BoNT/E compared with BoNT/A 
is varied, depending on the species and on the assays (Donald 2018). Higher doses may be 
needed to achieve demonstrable therapeutic responses.
For additional information, please refer to the IB.
2.3.
Benefit/Risk Assessment
Generally, the popularity of BoNT/A cosmetic treatment of GL in adults is related to its proven
efficacy for reducing moderate to severe facial lines (Beer 2006); well documented safety profile
(Brin 2009); and positive impact on psychological well-being and the resulting psychosocial 
benefits (Finn 2003). Compared with the general class of BoNT/A treatments, AGN-151586 may 
provide additional benefits. For one, it is provided as a ready-to-use liquid product and requires 
no reconstitution. Secondly, it offers the potential for faster onset of efficacy compared with the 
BoNT/A products.
Four controlled, Phase 2 clinical studies with AGN-151586 have been completed. In total, 103
participants have received a single study intervention cycle of AGN-151586 (highest exposure 
was 
U, and 41 participants have received placebo (identical to AGN-151586 but without 
toxin). Of those who received AGN-151586, headache (n = 2), vital capacity decreased (n = 2), 
pruritus/pruritus generalized (n = 2), and nausea (n = 1) were the only adverse events considered 
treatment-related by the investigator. These adverse events were mild to moderate in severity and 
resolved. The adverse event profile associated with AGN-151586 showed no unusual findings; 
no safety signal was identified.
The relevant anatomy and any alterations to the anatomy due to prior surgical procedures must 
be understood prior to administering AGN-151586, and care should be taken when injecting in 
or near vulnerable anatomic structures. Caution should also be exercised when AGN-151586 is 
used in the presence of inflammation at the proposed injection site(s) or when excessive 
weakness or atrophy is present in the target muscle. As is expected for any injection procedure, 
localized pain, inflammation, paresthesia, hypoesthesia, tenderness, swelling/edema, erythema, 
localized infection, bleeding, and/or bruising may be associated with the injection of

AGN-151586 or placebo. Needle-related pain and/or anxiety could result in vasovagal responses, 
including transient symptomatic hypotension and syncope.
In some cases, botulinum toxin effect may be observed beyond the site of local injection. The 
symptoms are consistent with the mechanism of action of botulinum toxin and may include 
asthenia, generalized muscle weakness, diplopia, ptosis, dysphagia, dysphonia, dysarthria, 
urinary retention, and breathing difficulties. These symptoms have been reported hours to weeks 
after injection. Swallowing and breathing difficulties can be life threatening, and there have been 
reports of death related to spread of toxin effects. The risk of symptoms is probably greatest in 
children treated for spasticity, but symptoms can also occur in adults treated for spasticity and 
other conditions, and particularly in those patients who have an underlying condition that would 
predispose them to these symptoms.
Reduced blinking has been reported after BoNT/A product injection to the orbicularis muscle, 
and can lead to corneal exposure, persistent epithelial defect, and corneal ulceration with 
perforation. For treatment of blepharospasm using a BoNT/A product, corneal perforation in an 
aphakic eye requiring corneal grafting has occurred because of this effect. Although these effects 
mentioned above have not been reported for BoNT/E, these may be anticipated because the 
mechanism of action of BoNT/E is similar to BoNT/A.
In addition to investigator and the sponsor’s MSP oversight, a DMC has been instituted to 
provide oversight in this study. The dose-escalation design of this study allows for careful review 
of select safety and efficacy data by the DMC to perform informed risk/benefit assessments prior 
to escalation to the next higher dose. The DMC may recommend proceeding with the nominal 
dose for the next cohort, request additional data, request to repeat the current dose or a lower 
dose, request an intermediate dose be evaluated (between the dose of the current cohort and the 
nominal dose for the next cohort), or request dose escalation be terminated.
More detailed information about the known and expected benefits and risks, reasonably expected 
adverse events of AGN-151586, and measures to control these risks can be found in the IB.

Study Design
4.1.
Overall Design

This is a multicenter, double-blind, randomized, placebo-controlled, dose-escalation 
study to evaluate the safety and efficacy of a single study intervention cycle of 
AGN-151586 in participants with moderate to severe GL.  

Participants are adults 18 to 65 years old, with moderate to severe GL at maximum frown 
(as assessed by the investigator using the FWS).

Up to 5 doses of AGN-151586 will be evaluated and compared with placebo in a 
sequential cohort design, starting with the lowest dose.

Each cohort will enroll a balanced distribution of participants with moderate or severe 
GL severity at maximum frown per investigator assessment (at least 40% and no more 
than 60% of either).

The primary efficacy measure is the investigator’s assessments of GL at maximum frown 
using the FWS.

Participants will undergo a Screening Visit up to 30 days before randomization on Day 1. 
All screening data must be available to the investigator prior to randomization on Day 1.

On Day 1, participants will be randomly assigned in a 3:1 ratio to receive AGN-151586 
or placebo. Enrollment stratification will be by baseline GL severity at maximum frown, 
assessed by the clinician (principal investigator or physician subinvestigator) using the
FWS.  

Study intervention on Day 1 will be administered as 5 injections in the glabellar complex 
(1 in the procerus and 2 in each corrugator).

Data Monitoring Committee
An internal DMC, independent from the study team, has been instituted to provide oversight in 
this study. Starting with Cohort 1, the DMC will convene to review select safety and efficacy 
data after the first subset of participants in Cohort 1 have completed the Day 14 visit. Following 
this review, the DMC will determine whether the study will proceed to Cohort 2 of dose 
escalation. After Cohort 2 proceeds, a similar review process will occur to determine whether 
Cohort 3 will proceed. This pattern repeats prior to the start of each new cohort. At each DMC 
review, data through Day 14 from a subset of participants (n ≥16) for any given cohort will be 
reviewed. Additionally, cumulative data from participants from the prior cohort(s) will also be 
included in the DMC review.  
At each DMC review, the DMC may recommend proceeding with the nominal dose for the next 
cohort, request additional data (eg, data from additional participants in the cohort, data from 
visits after Day 14), request to repeat the current dose or a lower dose, request an intermediate 
dose be evaluated (between the dose of the current cohort and the nominal dose for the next 
cohort), or request dose escalation be terminated. 
The dose-escalation design of this study allows for careful review of select safety and efficacy 
data by the DMC to assess risk/benefit prior to escalation to the next higher dose. Details of the 
activities and composition of the DMC are further described in the DMC charter.
4.1.1.
Clinical Hypotheses
Efficacy: A single study intervention cycle of AGN-151586 within the dose range evaluated is 
more effective than placebo in the treatment of GL, measured by investigators’ assessments of 
GL severity at maximum frown using the FWS.
Safety: A single study intervention cycle of AGN-151586 has an acceptable safety profile at the 
doses evaluated. 
4.2.
Scientific Rationale for Study Design
AGN-151586 is a BoNT/E product being developed for IM injections in the treatment of GL. 
Currently, this indication is commonly treated with BoNT/A products. AGN-151586 may offer a 
different treatment option to patients with its potential for faster onset of treatment effect. This 
study is designed to evaluate the tolerability and efficacy profiles of AGN-151586 for the

Study Intervention Compliance
Participants will receive all doses under the direct supervision of study center personnel. Study
intervention compliance will not be calculated because participants will receive all doses under 
the direct supervision of study center personnel.
The study site will keep an accurate drug disposition record that specifies the amount of study 
intervention administered to each participant and the date of administration.
6.5.
Concomitant Therapy
Concomitant therapy and/or medications considered necessary for the study participant’s welfare 
may be given at the discretion of the investigator.
The use of any medication during the study (including prescription or over-the-counter
medication, vitamins, and/or herbal supplements) is to be recorded on the participant’s eCRF at 
each visit along with the reason the medication is taken, dates of use, and dosing regimen.
Study site personnel must notify the sponsor immediately if a participant uses any concomitant 
medications not permitted by the protocol. Participants who admit to using prohibited 
concomitant medications may be discontinued from the study at the discretion of the investigator 
or sponsor.
6.5.1.
Prohibited Interventions
The decision to administer a prohibited medication/treatment is done with the safety of the 
participant as the primary consideration. When possible, the sponsor must be notified before the 
prohibited medication/treatment is administered. Co-administration of aminoglycosides or agents 
that could interfere with neuromuscular transmission (eg, curare-like agents) or muscle relaxants 
must be used with caution as the effects of the toxin, theoretically, could be potentiated.
No other facial cosmetic procedures or treatments are to be performed throughout the duration of 
the study. Prohibited treatments and procedures include, but are not limited to:

Oral retinoids

New or changes to regimen of topical hormone cream to the face

New or changes to regimen of topical retinoids to the face

Microdermabrasion to the face

Medium depth to deep facial chemical peels (ie, TCA and phenol)

Energy-based facial treatments (eg, intense pulsed light, Clear + Brilliant®, monopolar 
radiofrequency, microfocused ultrasound)

Facial lift (mid or full face)

Blepharoplasty

Synthetic implantation (eg, Gore-Tex) to the upper half of the face

Lost to Follow Up
A participant will be considered lost to follow-up if he or she repeatedly fails to return for 
scheduled visits and is unable to be contacted by the study site.
The following actions must be taken if a participant fails to return to the clinic for a required 
study visit:

The site must attempt to contact the participant and reschedule the missed visit as soon as 
possible and counsel the participant on the importance of maintaining the assigned visit 
schedule and ascertain whether the participant wishes to and/or should continue in the 
study.

Before a participant is deemed lost to follow-up, the investigator or designee must make 
every effort to regain contact with the participant (where possible, 3 telephone calls and,
if necessary, a certified letter to the participant’s last known mailing address or local
equivalent methods). These contact attempts will be documented in the participant’s 
medical record.

Should the participant continue to be unreachable, he/she will be considered to have 
withdrawn from the study.
Discontinuation of specific sites or of the study as a whole is handled as part of Appendix 1.

Study Assessments and Procedures

Study procedures and their timing are summarized in the SoA. Protocol waivers or 
exemptions are not allowed.

Immediate safety concerns should be discussed with the sponsor immediately upon 
occurrence or awareness to determine if the participant should continue or discontinue 
study intervention.

Adherence to the study design requirements, including those specified in the SoA, is 
essential and required for study conduct.

All screening evaluations must be completed and reviewed to confirm that potential 
participants meet all eligibility criteria. The investigator will maintain a screening log to 
record details of all participants screened and to confirm eligibility or record reasons for 
screening failure, as applicable.

The maximum amount of blood collected from each participant over the duration of the 
study for clinical laboratory and immunogenicity tests, including any extra assessments 
that may be required, will not exceed 250 mL. Repeat or unscheduled samples may be 
taken for safety reasons or for technical issues with the samples.

Facial Photography
Standardized digital facial photography will be performed prior to injection of study intervention 
for all participants and at the times shown in the SoA (Section 1.3). Images will be taken of each 
participant’s face from the front at rest and at maximum frown. Each site will receive 
documented training and instructions on taking photographs. 
Conditions of photography will be standardized across all photographs, including camera 
equipment, exposure, background, lighting, and focal length. Ideally, the same photographer will 
take all required photographs. A qualified third-party vendor will provide instructions for taking
photographs and processing digital photographs. All digital images will be transferred to the 
sponsor at the end of the study. 
Photographs will be taken for research purposes, and may also be used for education,
commercial, and/or marketing purposes. To participate in this study, the participant must consent
to having photographs taken for research but may still participate if he/she declines use of the
photographs for other purposes. The sponsor shall have full ownership rights to any photographs
derived from the study.

8.2.1.
Adverse Events
The investigator will question the participant to ascertain whether any adverse events were 
experienced since the previous visit. Additionally, the participants will be observed for at 
least 30 minutes following study intervention. All pertinent information regarding adverse events
(ie, date of onset and stop date, duration, outcome, seriousness, severity, relationship to study 
intervention, treatment required, action taken with study intervention, etc) will be obtained and 
recorded in the source documents and appropriate eCRF page.
8.2.2.
Physical Examinations
A full physical examination will be conducted at the Screening Visit and at the End-of-
Study/Early Exit Visit and includes the assessment of general appearance, HEENT, 
heart/cardiovascular function, lungs, abdomen, extremities, back, musculoskeletal function, 
lymphatic function, neurologic function, and skin. Abbreviated physical examinations will be 
conducted throughout the study as described in the SoA and limited to an examination of general 
appearance, heart, lungs, and abdomen.
Before study intervention, if the physical examination finding is clinically significant, the finding 
must be captured in the medical history eCRF. After study intervention, if the pre-existing 
finding becomes worse and is clinically significant or the new physical examination finding is 
clinically significant, it must be captured as an adverse event in the adverse event eCRF.
8.2.3.
Neurologic Assessment
The neurologic assessment comprises 2 elements, a Focused Symptoms Questionnaire and 
Focused Neurologic Examination that will be performed by trained physician investigators as 
described in the SOA. The neurologic assessment must be performed prior to randomization on 
Day 1, and is to be performed after adverse event assessment at all subsequent timepoints. See 
Appendix 8 for instructions for both elements.
Participants with any abnormal findings at Screening or Day 1 (prior to randomization), which 
meet exclusion criteria or may impact a participant’s safety or the interpretation of efficacy, will 
be excluded from the study. For participants who meet the inclusion/exclusion criteria, images of 
the face at natural smile and at rest will be captured at Day 1 (prior to randomization) in order to 
document baseline gross facial symmetry. These images will be referenced for the Focused 
Neurologic Examination.
8.2.4.
Vital Signs
Vital signs will be assessed as follows:

Pulse rate (beats per minute): Participants are to be seated for at least 2 minutes, and 
pulse rate will be counted over 60 seconds and recorded in the source document and 
eCRF as beats per minute.

Blood pressure (mm Hg): Participants are to be seated for at least 2 minutes, and 
systolic/diastolic blood pressure will be measured.

Respiration rate (breaths per minute): Participants are to be seated for at least 2 minutes, 
and breaths will be counted for 30 seconds and multiplied by 2.

When applicable, vital sign data will be collected prior to blood draws.

Body temperature will be taken.
Before study intervention, if the vital sign finding is clinically significant, it must be captured in 
the medical history eCRF. After study intervention, if the pre-existing finding becomes worse 
and is clinically significant or the new vital sign finding is clinically significant, it must be 
captured as an adverse event in the adverse event eCRF.
8.2.5.
Electrocardiograms

All participants will undergo conventional 12-lead ECG using standardized equipment 
and electrode placement at the visits outlined in the SoA. Participants are to be in a 
semirecumbent position for at least 10 minutes prior to starting the tracing. During 
screening, a 12-lead ECG trace will be taken to assess entry eligibility.

A qualified third-party vendor will read the ECGs and report the findings as normal, 
abnormal, or unable to evaluate.

For screening ECGs, prespecified significant abnormal findings will be flagged as 
exclusion alerts, and a third-party vendor will generate an exclusion alert for the site and 
the sponsor. Exclusion alerts are considered exclusionary for study eligibility (see 
Exclusion Criterion 1.05 in Section 5.2 which excludes any participant with a ‘clinically 
significant ECG abnormality at the Screening Visit’). For all subsequent ECGs, a 
qualified third-party vendor will also report the appearance of any new, prespecified 
significant abnormal findings and generate a protocol alert for the site and the sponsor.

The cardiologists will be blinded to participant study intervention assignments. If the 
ECG finding is abnormal, they will specify the abnormality or give a diagnosis, whenever 
it is possible. Electrocardiogram reports will be provided to the investigator and the 
sponsor via a secure portal within 24 hours of screening and within 72 hours for all other 
visits.

Before study intervention, if the ECG finding is clinically significant, it must be captured
in the medical history eCRF. After study intervention, if the pre-existing finding becomes 
worse and is clinically significant or the new ECG finding is clinically significant, it must 
be captured as an adverse event in the adverse event eCRF. Hard copies of the ECG 
tracings will be kept in the study files at the investigator’s site.

The ECG will be assessed for the following: heart rate, QRS duration, QT interval, QTcB 
interval, QTcF interval, ST segment, RR interval, PR interval, and qualitative results.
8.2.6.


At screening, the investigator will assess the clinical significance of any values outside 
the reference ranges provided by the laboratory, and participants with abnormalities 
judged to be clinically significant will be excluded from the study.

The investigator must review the laboratory report, document this review, and record any 
clinically relevant changes occurring during the study in the adverse event section of the 
eCRF. The laboratory reports must be filed with the source documents. Clinically 
significant abnormal laboratory findings are those which are not associated with the 
underlying disease, unless judged by the investigator to be more severe than expected for 
the participant’s condition.

All laboratory tests with values considered clinically significant during participation in 
the study, including the End-of-Study/Early Exit Visit, should be repeated until the values 
return to normal or baseline or are no longer considered clinically significant by the 
investigator or MSP.
o
If such values do not return to normal/baseline within a period of time judged
reasonable by the investigator, the etiology should be identified and the sponsor 
notified.
o
All protocol-required laboratory assessments, as defined in Appendix 2, must be 
conducted in accordance with the laboratory manual and the SoA.
o
If laboratory values from nonprotocol specified laboratory assessments performed 
at the institution’s local laboratory require a change in participant management or 
are considered clinically significant by the investigator (eg, SAE or adverse event
or dose modification), then the results must be recorded in the eCRF.
8.2.7.
Urine Pregnancy Test
Urine dipstick kits will be used to conduct pregnancy tests at the timepoints specified in the SoA, 
or more frequently at the investigator’s discretion.
8.2.8.
Suicidal Risk Monitoring
Suicidal risk monitoring is not applicable for this study.
8.3.
Adverse Events and Serious Adverse Events
The definitions of an adverse event or SAE can be found in Appendix 3.
Adverse events will be reported by the participant.
The investigator and any qualified designees are responsible for detecting, documenting, and 
recording events that meet the definition of an adverse event or SAE and remain responsible for 
following up adverse events that are serious, considered related to the study intervention or study 
procedures, or that caused the participant to discontinue the study intervention (see Section 7).

8.3.1.
Time Period and Frequency for Collecting Adverse Event and Serious Adverse 
Event Information
All SAEs and adverse events from the signing of the ICF will be collected at the timepoints 
specified in the SoA (Section 1.3), and as observed or reported spontaneously by study 
participants.
Medical occurrences that begin before the start of study intervention, but after obtaining 
informed consent will be recorded in the adverse event section of the eCRF and will be 
considered pretreatment adverse events.
All SAEs will be recorded and reported to the sponsor or designee within 24 hours, as indicated 
in Appendix 3. The investigator will submit any updated SAE data to the sponsor within 
24 hours of it being available.
Investigators are not obligated to actively seek adverse event or SAE information after 
conclusion of the study participation. However, if the investigator learns of any SAE, including a 
death, at any time after a participant has been discharged from the study, and he/she considers 
the event to be reasonably related to the study intervention or study participation, the investigator 
must promptly notify the sponsor.
The method of recording, evaluating, and assessing causality of adverse events and SAEs and the 
procedures for completing and transmitting SAE reports are provided in Appendix 3.
8.3.2.
Method of Detecting Adverse Events and Serious Adverse Events
Care will be taken not to introduce bias when detecting adverse events and/or SAEs. Open-ended 
and nonleading verbal questioning of the participant is the preferred method to inquire about 
adverse event occurrences.
8.3.3.
Follow-up of Adverse Events and Serious Adverse Events
After the initial adverse event/SAE report, the investigator is required to proactively follow each 
participant at subsequent visits/contacts. All adverse events/SAEs will be followed until 
resolution, stabilization, the event is otherwise explained, or the participant is lost to follow-up 
(as defined in Section 7.3).
The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as medically indicated or as requested by the sponsor to 
elucidate the nature and/or causality of the adverse event or SAE as fully as possible. This may 
include additional laboratory tests or investigations, histopathological examinations, or 
consultation with other health care professionals.
If a participant dies during participation in the study or during a recognized follow-up period, the 
investigator will provide the sponsor with a copy of any postmortem findings including 
histopathology. 
New or updated information will be recorded in the originally completed eCRF.

Regulatory Reporting Requirements for Serious Adverse Events

Prompt notification by the investigator to the sponsor of a SAE is essential so that legal 
obligations and ethical responsibilities towards the safety of participants and the safety of 
a study intervention under clinical investigation are met. 

The sponsor has a legal responsibility to notify both the local regulatory authority and 
other regulatory agencies about the safety of a study intervention under clinical 
investigation. The sponsor will comply with country-specific regulatory requirements 
relating to safety reporting to the regulatory authority, IRBs/IECs, and investigators.

An investigator who receives an investigator safety report describing an SAE or other 
specific safety information (eg, summary or listing of SAEs) from the sponsor will 
review and then file it along with the IB and will notify the IRB/IEC, if appropriate 
according to local requirements.

Investigator safety reports must be prepared for SUSARs according to local regulatory 
requirements and sponsor policy and forwarded to investigators as necessary.
8.3.5.
Pregnancy

Details of all pregnancies, including pregnancy outcome, in female participants and 
consented female partners of male participants will be collected; pregnancies include 
those with onset after study intervention, and until 10 weeks after study intervention for 
female participants and until 6 weeks after study intervention for female partners of male 
participants.

At each visit, site personnel must discuss with WOCBP and males with partners who are 
WOCBP compliance with contraceptive use.

Urine pregnancy testing will be conducted for WOCBP at the Screening Visit, prior to 
randomization at Day 1, at the study exit visit, and at the discretion of the investigator. 
See Appendix 7 for detailed information on definition of WOCBP, use of contraceptives,
and pregnancy.

Women who test positive for urine pregnancy test prior to randomization will NOT 
receive treatment and will be discontinued from the study.

If a pregnancy is confirmed after the participant has received study intervention, the 
participant may choose to exit the study after appropriate safety follow-up or remain in 
the study for all safety and efficacy follow-up assessments.

Any termination of pregnancy will be reported, regardless of fetal status (presence or 
absence of anomalies) or indication for the procedure.


If a pregnancy is reported, the investigator should inform the sponsor within 24 hours of 
learning of the pregnancy and should follow the procedures outlined in Appendix 7.

Abnormal pregnancy outcomes (eg, spontaneous or elective abortion, fetal death, 
stillbirth, congenital anomalies, ectopic pregnancy) or genetic abnormalities (whether 
leading to an elective abortion or not) are considered SAEs.
8.3.6.
Adverse Events of Special Interest
There are no AESIs for this study because they are not clinically indicated. 
8.3.7.
Medication Errors
Medication error refers to any unintended error in the dosing and/or administration of the study 
intervention as per instructions in the protocol. Medication errors generally fall into 4 categories 
as follows:

Wrong study intervention

Wrong dose (including dosing regimen, strength, form, concentration, amount)

Wrong route of administration

Wrong participant (ie, not administered to the intended participant)
Medication errors include occurrences of overdose and underdose of the study intervention.
Overdose: Unintentional administration of a quantity of the study intervention given per 
administration that is above the maximum recommended dose according to the protocol for the 
study intervention. See Section 8.4 for information of treatment of overdose.
Underdose: Unintentional administration of a quantity of the study intervention given per 
administration that is under the minimum recommended dose according to the protocol. 
8.4.
Treatment of Overdose
Overdose of AGN-151586 is a relative term and depends upon dose, site of injection, and 
underlying tissue properties. Signs and symptoms of overdose are likely not to be apparent 
immediately postinjection. Excessive doses may produce local, or distant, generalized and
profound neuromuscular paralysis.
Because AGN-151586 is administered as injections by physicians, for this study, the chance of 
overdose is extremely low. Should accidental injection occur or overdose be suspected, the 
participant should be medically monitored for up to several weeks for progressive signs or 
symptoms of systemic muscular weakness that could be local or distant from the site of injection, 
which may include ptosis, diplopia, dysphagia, dysarthria, generalized weakness, or respiratory 
failure. Eyelid ptosis, diplopia, or vision blurred are known local effects of BoNT/A during 
treatment of glabellar lines, which may also occur with BoNT/E. These participants should be 
considered for further medical evaluation and appropriate medical therapy immediately
instituted, which may include hospitalization.

If the musculature of the oropharynx and esophagus is affected, aspiration may occur, which may 
lead to development of aspiration pneumonia. If the respiratory muscles become paralyzed or 
sufficiently weakened, intubation and assisted respiration may be necessary until recovery takes 
place. Supportive care could involve the need for a tracheostomy and/or prolonged mechanical 
ventilation, in addition to other general supportive care.
In the event of an overdose, the investigator should:
1. Contact the MSP immediately.
2. Closely monitor the participant for any AE/SAE.
3. Document the quantity of the excess dose in the eCRF.

Biomarkers and Other Assessments
Immunogenicity Assessments
Validated assays will be used to assess the presence of antidrug antibodies to AGN-151586, 
using blood samples collected during the course of the study.  
Blood samples for immunogenicity testing will be collected from each participant at Screening, 
and at the Day 7, Day 28, and End-of-Study visits. Collected samples (approximately 20 mL per 
sample) will be processed to yield serum for analysis.
Detection of binding antibodies against AGN-151586 in participants’ serum will be carried out
using the validated ELISA in a 3-tier format (screening, confirmation, and titering). Only 
samples that are confirmed positive in the confirmatory assay will be stored and analyzed for
presence of neutralizing antibodies to AGN-151586 when a validated assay becomes available.
These samples may also be used for additional characterization of antibody response to other 
neurotoxin subtype(s). The findings from this exploratory analysis will be documented in the 
clinical study report or in a separate report. The ICF will contain a separate appendix that 
addresses the use of immunogenicity samples for this optional exploratory research. The

Statistical Considerations
9.1.
Statistical Hypotheses
The following hypotheses will be used to compare each dose group of AGN-151586 with
placebo:

Null hypothesis: AGN-151586 and placebo are equally effective in the probability of 
reducing GL severity at maximum frown as measured by a ≥2-grade improvement from
baseline based on the investigator-rated FWS at any posttreatment timepoint through Day 7.

Alternative hypothesis: AGN-151586 and placebo are not equally effective in the 
probability of reducing GL severity at maximum frown as measured by a ≥2-grade
improvement from baseline based on the investigator-rated FWS at any posttreatment 
timepoint through Day 7.
9.2.
Sample Size Determination
For each cohort, there will be approximately 40 participants (AGN-151586: n = 30; placebo: 
n = 10) with a 3:1 randomization allocation; up to 5 dose cohorts are planned. For a cohort of 30 
participants treated with AGN-151586, there is an approximately 60% chance of detecting an
adverse event which occurs at a 3% incidence (eg, eyelid ptosis).
Approximately 200 participants will be randomized to have approximately 180 participants 
complete the study based on an anticipated dropout rate of 10%. Approximately 150 participants
are expected to have a single dose exposure to AGN-151586 with an approximately 78% chance to
detect any adverse event at a 1% incidence, and a 95% chance to detect any adverse event at a 
2% incidence.
The primary efficacy analysis will be conducted on the mITT population, which consists of 
randomized participants who have been dosed and have a posttreatment measurement of 
investigator-rated FWS at maximum frown. A sample size of 40 participants per cohort will have 
approximately 87% power to detect a difference between an AGN-151586 dose group and the 
placebo group, assuming a 10% dropout rate and responder rates of 70% for the AGN-151586 
study intervention group and 10% for the placebo group.
The calculation is based on a 2-sided Chi-squared test (Fisher’s exact test) with a 0.05 
significance level using nQuery Advisor version 7.0. 
9.3.
Populations for Analyses
For the efficacy analyses, the mITT population will be used and include all randomized 
participants who received study intervention and who had a posttreatment investigator-rated 
FWS measurement at maximum frown. The safety analysis will be performed using the safety 
population that includes all participants who received study intervention. All analyses will be 
performed on an as-treated basis.

Statistical Analyses
The SAP will be developed and finalized before database lock and unblinding, and will describe 
the participant populations to be included in the analyses, along with procedures for accounting 
for missing, unused, and spurious data. This section is a summary of the planned statistical 
analyses of the primary and exploratory endpoints.
9.4.1.
Efficacy Analyses
9.4.1.1.
Primary Efficacy Endpoints
The efficacy endpoint is the achievement of a ≥ 2-grade improvement from baseline on the FWS 
according to investigator assessments of GL severity at maximum frown at any postintervention 
timepoint through Day 7.
9.4.1.2.
Primary Efficacy Analyses
The purpose of the primary analyses is to test for the primary endpoint, that is, the achievement 
of a ≥2-grade improvement in FWS according to investigator assessments of GL severity at 
maximum frown from Day 1 through Day 7 for each cohort. Safety will be assessed by the 
DMC.

The purpose of the primary analyses will be to test for the primary endpoint (ie, at least a
2-grade improvement response from investigator) during any timepoint after study
intervention administration through Day 7 for each AGN-151586 intervention dose group 
versus placebo group for each cohort. For example, if it is determined by the investigator-
rated FWS that participants have at least a 2-grade improvement at any postintervention 
assessment through Day 7, they will meet the responder definition for each assessment 
timepoint this applies.

The proportion of responders for the primary endpoint for each AGN-151586 study 
intervention group versus placebo will be analyzed using CMH tests stratified by baseline 
GL severity at maximum frown, using observed data without imputation or adjustment 
for multiplicity. In addition, 2-sided 95% CIs for the treatment differences in response 
rates will be provided. Between group comparisons will only be performed for each 
AGN-151586 group against the placebo group. Nominal p-values will be presented for 
each statistical test.

Observed data without imputation will be used with stratification based on baseline GL 
severity for the primary analysis described above. In addition, sensitivity analyses of the 
primary efficacy variable will be performed to establish consistency and robustness and
further characterize the extent of participants’ responses (eg, missing as 
nonresponder). In addition, placebo groups across cohorts can be pooled to compare with 
each AGN-151586 group as a supportive analysis.  Details will be provided in the SAP.

Baseline and posttreatment values will be summarized using descriptive statistics for the AGN-
151586 dose groups and placebo group for each cohort at each assessment timepoint. Details will 
be provided in the SAP.
9.4.2.
Safety Analyses
The safety analysis will be performed using the safety population and will be defined in the SAP. 
The safety parameters will include:

Incidence of adverse events, including adverse event severity and causality as assessed by 
the investigator

Change from baseline and values over time in clinical laboratory tests, physical 
examinations, vital signs, and ECGs
9.4.2.1.
Adverse Events
An adverse event will be considered a TEAE if:

The adverse event began on or after the date and time of the study intervention; or

The adverse event was present before the date and time of the study intervention, but 
increased in severity or became serious on or after the date and time of the study 
intervention.
An adverse event that occurs after the End-of-Study Visit (Day 42) will not be counted as a 
TEAE.
An adverse event will be considered a TESAE if it is a TEAE that additionally meets any SAE 
criteria.
The number and percentage of participants reporting TEAEs in each study intervention group
will be tabulated by system organ class and preferred term and by system organ class, preferred
term, and severity.
The number and percentage of participants reporting treatment-related TEAEs in each study 
intervention group will be tabulated by system organ class and preferred term.
If more than 1 adverse event is coded to the same preferred term for the same participant, the 
participant will be counted only once for that preferred term using the most severe and most 
related occurrence for the summaries by severity and causality.
The causality and severity of all adverse events will be assessed by the investigator.
The number and percentage of participants reporting TEAEs that are included in the PDSOT 
term list will be tabulated by study intervention group. The PDSOT term list will be included in 
the SAP.

Summary tables will be provided for participants with TESAEs and participants with TEAEs
leading to discontinuation if 5 or more participants reported such events. Listings of all adverse 
events, SAEs, and adverse events leading to discontinuation by participant will be presented.
The definitions of an adverse event and SAE can be found in Appendix 3.
9.4.2.2.
Clinical Laboratory Assessments
Descriptive statistics for clinical laboratory values (in SI units) at baseline (screening) and 
changes from baseline at each assessment will be presented by study intervention for each 
clinical laboratory assessment.
The criteria for PCS laboratory values will be detailed in the SAP. The number and percentage of 
participants who have PCS postbaseline clinical laboratory values will be tabulated by study 
intervention at each assessment. The percentages will be calculated relative to the number of 
participants who have available non-PCS baseline values and at least 1 postbaseline assessment. 
The numerator will be the total number of participants with at least 1 PCS postbaseline value. A 
supportive listing of participants with PCS postbaseline values will be provided for the safety 
population. 
9.4.2.3.
Vital Signs
Descriptive statistics for vital signs (systolic and diastolic blood pressure, pulse rate, respiration 
rate, body temperature) at baseline prior to receiving study intervention (or screening value just 
prior to baseline if baseline values are not available) and changes from baseline at each 
assessment will be presented by study intervention.
The criteria for PCS vital signs will be detailed in the SAP. The number and percentage of 
participants who have PCS postbaseline vital signs will be tabulated by study intervention at 
each assessment. The percentages will be calculated relative to the number of participants who 
have available non-PCS baseline values and at least 1 postbaseline assessment. The numerator 
will be the total number of participants with at least 1 PCS postbaseline value. A supportive 
listing of participants with PCS postbaseline values will be provided for the safety population.
9.4.2.4.
Electrocardiograms
Electrocardiogram evaluations by investigators are captured in the eCRF and are classified into 3 
categories: normal, abnormal, or not evaluable. These data will be summarized by study 
intervention group as the number and percent of participants in each category at each visit. Data 
listings which include ECG basic parameters and any ECG abnormalities will be produced.

c.
Requires inpatient hospitalization or prolongation of existing hospitalization
In general, hospitalization signifies that the participant has been detained (usually 
involving at least an overnight stay) at the hospital or emergency ward for observation 
and/or intervention that would not have been appropriate in the physician’s office or 
outpatient setting. Complications that occur during hospitalization are AEs. If a 
complication prolongs hospitalization or fulfills any other serious criteria, the event is 
serious. When in doubt as to whether hospitalization occurred or was necessary, the AE 
should be considered serious.
Hospitalization for elective intervention of a pre-existing condition that did not worsen 
from baseline is not considered an AE.
d.
Results in persistent disability/incapacity

The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions.

This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhea, influenza, 
and accidental trauma (eg, sprained ankle) which may interfere with or prevent 
everyday life functions but do not constitute a substantial disruption.
e.
Is a congenital anomaly/birth defect
f.
Other situations:

Medical or scientific judgment should be exercised in deciding whether SAE 
reporting is appropriate in other situations such as important medical events that may 
not be immediately life threatening or result in death or hospitalization but may 
jeopardize the participant or may require medical or surgical intervention to prevent 
one of the other outcomes listed in the above definition. These events should usually 
be considered serious.
Examples of such events include invasive or malignant cancers, intensive 
intervention in an emergency room or at home for allergic bronchospasm, blood 
dyscrasias or convulsions that do not result in hospitalization, or development of 
drug dependency or drug abuse.

Appendix 7: Contraceptive Guidance and Collection of Pregnancy 
Information
Definitions:
Woman of Childbearing Potential
A woman is considered fertile following menarche and until becoming postmenopausal unless 
permanently sterile (see below).
Women in the following categories are not considered WOCBP:
1. Premenarchal
2. Premenopausal female with 1 of the following:

Documented hysterectomy

Documented bilateral salpingectomy

Documented bilateral oophorectomy
Note: Documentation can come from the site personnel’s review of the participant’s 
medical records, medical examination, or medical history interview.
3. Postmenopausal female

A postmenopausal state is defined as no menses for 12 months without an alternative 
medical cause. A high follicle-stimulating hormone (FSH) level in the postmenopausal 
range may be used to confirm a postmenopausal state in women not using hormonal 
contraception or hormonal replacement therapy (HRT). However, in the absence of 
12 months of amenorrhea, a single FSH measurement is insufficient. 

Females on HRT and whose menopausal status is in doubt will be required to use one of
the nonestrogen hormonal highly effective contraception methods if they wish to continue 
their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation 
of postmenopausal status before study enrollment.
Contraception Guidance:
Male Participants
Nonvasectomized male participants with female partners of childbearing potential are eligible to 
participate if they agree to ONE of the following during the study and for at least 6 weeks after 
administration of study intervention: 

Are abstinent from penile-vaginal intercourse as their usual and preferred lifestyle 
(abstinent on a long-term and persistent basis) and agree to remain abstinent


Agree to use a male condom with spermicide plus partner use of a contraceptive method 
with a failure rate of < 1% per year as described in Table 10-2 when having penile-vaginal 
intercourse with a woman of childbearing potential who is not currently pregnant
In addition, nonvasectomized male participants must refrain from donating sperm for the 
duration of the study and for at least 6 weeks after study intervention.
Nonvasectomized male participants with a pregnant or breastfeeding partner must agree to 
remain abstinent from penile-vaginal intercourse or use a male condom during each episode of 
penile penetration during the study and for at least 6 weeks after administration of study 
intervention.

Pregnancy Testing:

Pregnancy testing will be performed according to instructions provided in the pregnancy 
test kit.

WOCBP should only be included after a confirmed menstrual period and a negative urine
pregnancy test at Day 1.

Additional pregnancy testing is not required during the study other than at the End-of-
Study/Early Exit Visit.

Pregnancy testing will be performed whenever a menstrual cycle is missed or when 
pregnancy is otherwise suspected at the discretion of the investigator.
Collection of Pregnancy Information:
Male Participants with Partners Who Become Pregnant 

The investigator will attempt to collect pregnancy information on any male participant’s 
female partner who becomes pregnant while the male participant is in this study. This 
applies only to male participants who receive study intervention.

After obtaining the necessary signed informed consent from the pregnant female partner 
directly, the investigator will record pregnancy information on the appropriate form and 
submit it to the sponsor within 24 hours of learning of the partner’s pregnancy. The female 
partner will also be followed to determine the outcome of the pregnancy. Information on 
the status of the mother and child will be forwarded to the sponsor. Generally, the follow-
up will be no longer than 6 to 8 weeks following the estimated delivery date. Any 
termination of the pregnancy will be reported regardless of fetal status (presence or 
absence of anomalies) or indication for the procedure. 
Female Participants Who Become Pregnant 

The investigator will collect pregnancy information on any female participant who 
becomes pregnant while participating in this study. Information will be recorded on the 
appropriate form and submitted to the sponsor within 24 hours of learning of a 
participant’s pregnancy. The participant will be followed to determine the outcome of the 
pregnancy. The investigator will collect follow-up information on the participant and the 
neonate, and the information will be forwarded to the sponsor. Generally, follow-up will 
not be required for longer than 6 to 8 weeks beyond the estimated delivery date. Any 
termination of pregnancy will be reported, regardless of fetal status (presence or absence 
of anomalies) or indication for the procedure.


While pregnancy itself is not considered to be an adverse event or SAE, any pregnancy 
complication will be reported as an adverse event or SAE. A spontaneous or elective 
abortion is always considered to be an SAE and will be reported as such. Any poststudy 
pregnancy-related SAE considered reasonably related to the study intervention by the 
investigator will be reported to the sponsor as described in Section 8.3.4. While the 
investigator is not obligated to actively seek this information in former study participants, 
he or she may learn of an SAE through spontaneous reporting. 

Any female participants who becomes pregnant while participating in the study after 
receiving study intervention may choose to exit the study after appropriate safety follow-
up or remain in the study for all safety and efficacy follow-up assessments.
