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 the sponsor. 
The use of any concomitant medication or vaccine, (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. 
Concomitant therapy and/or medications considered necessary for the study participant’s welfare 
may be given at the discretion of the investigator. 
If concomitant medications may have an effect on efficacy or safety outcomes, these medications 
should be administered in dosages that remain constant throughout the course of the trial at the 
discretion of the investigator. 
If the permissibility of a specific medication/treatment is in question, please contact the sponsor.

Notification of early participant discontinuation from the study and the reason for 
discontinuation will be made to the sponsor and will be clearly documented in the appropriate 
eCRF.  
The sponsor should be consulted in advance of withdrawal whenever possible. Every effort 
should be made to retain participants in the study until completion as much as possible. 
Participants who are withdrawn from the study may not be re-enrolled but will be asked to 
undergo all early withdrawal activities. Definitions of the standard terms are provided in

7.1. 
Discontinuation of Study Intervention 
If a participant does not tolerate study injections, the participant will be observed until the 
intolerability has either resolved or satisfactorily stabilized in the judgement of the investigator 
and the participant may choose to exit the study or to remain in the study for all safety follow-up 
assessments through the EOS Visit. 
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 to remain in the study for all 
safety and efficacy follow-up assessments through the EOS visit.  
7.2. 
Participant Discontinuation/Withdrawal from the Study 
• A participant may withdraw from the study at any time at his/her own request or may be 
withdrawn at any time at the discretion of the investigator for safety, behavioral, compliance, 
or administrative reasons.

• If the participant withdraws consent for disclosure of future information, the sponsor may 
retain and continue to use any data collected before such a withdrawal of consent. 
• See the SoA for data to be collected at the time of study discontinuation and follow-up and 
for any further evaluations that need to be completed. 
7.3. 
Lost to Follow Up 
A participant will be considered lost to follow-up if he/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 or not 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. 
8. 
Study Assessments and Procedures 
• Study procedures and their timing are summarized in the SoA (Section 1.2).  
• 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 schedule of 
assessments, 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. During the Screening Period, the investigator or 
subinvestigator will assess the clinical significance of any physical examination findings. 
Any participants with abnormalities judged to meet exclusion criteria will be excluded from 
the study.

The investigator and any qualified designees are responsible for collecting, detecting, 
documenting, and recording events that meet the definition of an AE or SAE and any other 
study-specific term as relevant and remain responsible for following up AEs that are serious, 
considered related to the study intervention or study procedures, or that caused the participant to 
discontinue the study (see Section 7). 
8.3.1. 
Time Period and Frequency for Collecting Adverse Event and Serious Adverse 
Event Information 
All SAEs from the signing of the ICF until the follow-up visit will be collected at the timepoints 
specified in the SoA (Section 1.2), and as observed or reported spontaneously by study 
participants. 
All AEs from the signing of the ICF until the follow-up visit will be collected at the timepoints 
specified in the SoA (Section 1.2), 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 AE section of the eCRF. 
All SAEs will be recorded and reported to the sponsor or designee within 24 hours of awareness, 
as indicated in Appendix 3. The investigator will submit any updated SAE data to the sponsor 
within 24 hours of it being available.  
AESIs are described below in Section 8.3.6 and in Appendix 3. 
Investigators are not obligated to actively seek AE 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 AEs 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 AEs and/or SAEs. Open-ended and 
non-leading verbal questioning of the participant is the preferred method to inquire about 
AE occurrences. 
8.3.3. 
Follow-up of Adverse Events and Serious Adverse Events 
After the initial AE/SAE report, the investigator is required to proactively follow each participant 
at subsequent visits/contacts. All SAEs and AESI (as defined in Section 8.3.6) 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 AE 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. 
The investigator will submit any updated SAE data to the sponsor within 24 hours of receipt of 
the information. 
8.3.4. 
Regulatory Reporting Requirements for Serious Adverse Events 
• Prompt notification by the investigator to the sponsor of an 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. 
• Investigator safety reports must be prepared for SUSARs according to local regulatory 
requirements and sponsor policy and forwarded to investigators as necessary. 
• 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. 
8.3.5. 
Pregnancy 
• 
Details of all pregnancies in female participants will be collected after the start of study 
intervention and until the EOS. 
• 
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) are considered SAEs.

Primary and Secondary Analyses 
The proportion of responders will be analyzed using CMH tests 
 
. In addition, 2-sided 95% confidence intervals for the treatment differences in response 
rates will be provided. Between group comparisons will only be performed for each BOTOX 
group against the placebo group, and BOTOX high dose group against the BOTOX low dose 
group. 
9.4.2. 
Safety Analyses 
The safety analyses will be performed using the safety population and will be fully defined in the 
SAP. The safety parameters will include AEs and vital signs. For each safety parameter, the last 
nonmissing safety assessment before the first dose of study intervention will be used as the 
baseline for all analyses of that safety parameter. 
9.4.2.1. 
Adverse Events 
An AE will be considered a TEAE if: 
• The AE began after the first dose of study intervention; or 
• The AE was present before the first dose of study intervention, but increased in severity or 
became serious after the first dose of study intervention 
An AE will be considered a serious TEAE if it is a TEAE that additionally meets any SAE 
criteria. 
The total number and percentage of participants reporting AEs, TEAEs, treatment-related 
TEAEs, serious TEAEs, treatment-related serious TEAEs, deaths, and discontinuations due to 
TEAEs will be summarized for each treatment group. 
The number and percentage of participants reporting TEAEs in each study intervention group 
will be tabulated by system organ class, preferred term, and severity. 
The number and percentage of participants reporting serious TEAEs in each study intervention 
group will be tabulated by system organ class and preferred term. 
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 AE is coded to the same PT 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 summarizations by severity and by relationship to study intervention.  
The number and percentage of participants reporting TEAEs that are included in the possible 
distant spread of toxin (PDSOT) term list in each study intervention group will be tabulated by 
preferred term. The PDSOT term list will be provided by the medical safety physician (MSP).  
The PDSOT will be reviewed by the MSP on a monthly basis for monitoring severity, frequency, 
and trending.

Data Quality Assurance 
• All participant data relating to the study will be recorded on printed or eCRFs unless 
transmitted to the sponsor or designee electronically. The investigator is responsible for 
verifying that data entries are accurate and correct by electronically signing the eCRF.  
• The investigator must maintain accurate documentation (source data) that supports the 
information entered in the eCRF.  
• The investigator must permit study-related monitoring, audits, IRB/IEC review, and 
regulatory agency inspections and provide direct access to source data documents.  
• The sponsor or designee is responsible for the data management of this study including 
quality checking of the data.  
• Study monitors will perform ongoing source data verification to confirm that data entered 
into the CRF by authorized site personnel are accurate, complete, and verifiable from source 
documents; that the safety and rights of participants are being protected; and that the study is 
being conducted in accordance with the currently approved protocol and any other study 
agreements, ICH GCP, and all applicable regulatory requirements.  
• Records and documents, including signed ICFs, pertaining to the conduct of this study must 
be retained by the investigator as stated in the clinical trial agreement. No records may be 
destroyed during the retention period without the written approval of the sponsor. No records 
may be transferred to another location or party without written notification to the sponsor.  
10.1.7. 
Source Documents 
• Source documents provide evidence for the existence of the participant and substantiate the 
integrity of the data collected. Source documents are filed at the investigator’s site. 
• Data entered in the eCRF that are transcribed from source documents must be consistent with 
the source documents or the discrepancies must be explained. The investigator may need to 
request previous medical records or transfer records, depending on the study. Also, current 
medical records must be available. 
• Definition of what constitutes source data can be found in Section 4.0 of ICH E6, Good 
Clinical Practice: Consolidated Guidance and must follow ALCOA, ie, records must be 
attributable, legible, contemporaneous, original, and accurate.

Study and Site Closure 
The sponsor designee reserves the right to close the study site or terminate the study at any time 
for any reason at the sole discretion of the sponsor. Study sites will be closed upon study 
completion. A study site is considered closed when all required documents and study supplies 
have been collected and a study-site closure visit has been performed. 
The investigator may initiate study-site closure at any time, provided there is reasonable cause 
and sufficient notice is given in advance of the intended termination. 
Reasons for the early closure of a study site by the sponsor or investigator may include but are 
not limited to: 
• Failure of the investigator to comply with the protocol, the requirements of the IRB/IEC or 
local health authorities, the sponsor’s procedures, or GCP guidelines 
• Inadequate recruitment of participants by the investigator 
• Discontinuation of further development of study intervention

Publication Policy 
• Allergan as the sponsor has proprietary interest in this study. Authorship and manuscript 
composition will reflect joint cooperation between multiple investigators and sites and 
Allergan personnel. Authorship will be established prior to the writing of the manuscript. As 
this study involves multiple centers, no individual publications will be allowed prior to 
completion of the final report of the multicenter study except as agreed with Allergan.  
• The sponsor will comply with the requirements for publication of study results. In 
accordance with standard editorial and ethical practice, the sponsor will generally support 
publication of multicenter studies only in their entirety and not as individual site data. 
• Authorship will be determined by mutual agreement and in line with International Committee 
of Medical Journal Editors authorship requirements.

treatment. An AE can therefore be any unintended sign (including 
an abnormal laboratory finding), symptom, or disease temporally 
associated with the use of a medicinal (investigational) product, 
whether or not related to the medicinal (investigational) product.

Appendix 7: Contraceptive Guidance and Collection of Pregnancy 
Information 
Definitions: 
Woman of Childbearing Potential (WOCBP) 
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.  
Contraception Guidance: 
Female Participants 
Female participants of childbearing potential are eligible to participate if they agree to use a 
highly effective method or acceptable method of contraception consistently and correctly as 
described in Table 10–1.

• 
Etonogestrel implant (ie, Nexplanon®) 
Bilateral tubal occlusion 
Intrauterine copper contraceptive (ie, ParaGard®) 
Vasectomized Partner  
A vasectomized partner is a highly effective contraception method provided that the partner is the sole male 
sexual partner of the WOCBP and the absence of sperm has been confirmed. If not, an additional highly effective 
method of contraception should be used.  
Sexual Abstinence  
Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual 
intercourse during the entire period of risk associated with the study intervention. The reliability of sexual 
abstinence needs to be evaluated in relation to the duration of the study and the preferred and usual lifestyle of 
the participant.  
Acceptable Methods  
Acceptable birth control methods that result in a failure of more than 1% per year include: 
• 
Progestogen-only oral hormonal contraception, where inhibition of ovulation is not the primary mode of 
action 
• 
Male or female condom with or without spermicide  
• 
Cap, diaphragm, or sponge with spermicide 
• 
Nonhormonal intrauterine device  
A combination of male condom with either cap, diaphragm, or sponge with spermicide (double-barrier methods) 
are also considered acceptable, but not highly effective, birth control methods. 
a Typical use failure rates may differ from those when used consistently and correctly. Use should be consistent 
with local regulations regarding the use of contraceptive methods for participants participating in clinical 
studies.

Pregnancy Testing: 
• 
WOCBP should only be included after a confirmed menstrual period and a negative highly 
sensitive pregnancy test at screening and also a negative test on Day 1. 
• 
Additional pregnancy testing may also be performed at any other study visit at the 
investigator’s discretion and at the study exit visit, and as required locally. 
• 
Pregnancy testing will be performed whenever a menstrual cycle is missed or when 
pregnancy is otherwise suspected.  
Collection of Pregnancy Information: 
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 AE or SAE, any pregnancy complication 
will be reported as an AE 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.  
• 
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 to remain in the 
study for all safety and efficacy follow-up assessments through the end-of-study visit.

INTRODUCTION 
This statistical analysis plan (SAP) provides a more technical and detailed elaboration of 
the statistical analyses of the efficacy and safety data as outlined and/or specified in the 
protocol of Study 1936-201-008 (Amendment 1 dated 12 August 2019). Specifications of 
tables, figures, and data listings will be provided in a separate document. 
Analyses for patient-reported outcomes (PROs) will be specified in a separate document, 
and the results will be summarized in a separate report. However, analyses for the 
Participant Allergan Platysma Prominence Scale (P-APPS) will be described in this 
document. 
Study 1936-201-008 is a Phase 2, multicenter, randomized, double-blind, 
placebo-controlled, parallel-group, dose-ranging study. 
 
 
 
 
 
 Platysma prominence will be assessed at maximum contraction by the 
investigator using the C-APPS and by the participant using the P-APPS. 
The length of this study will be approximately 4 months for each participant. Signed 
informed consent from the participant will be obtained at Screening (Day -14 to Day -7) 
before any study-related procedures. After verification that the participant meets all 
inclusion and exclusion criteria, and completion of all baseline study procedures, the 
participant will be randomized in a 1:1:1 ratio to receive BOTOX® high dose, BOTOX 
low dose or placebo at Visit 2/Day 1. 
 
 
 
 
 After 
randomization on Day 1, participants will return to the research facility at Days 7, 14, 30, 
60, and 90 (Visits 3 to 7, respectively) for protocol-defined efficacy and safety 
assessments. Study exit protocol-defined assessments will occur at Day 120 (Visit 8) or at 
early termination. 
The schedule of activities is presented in Table 4-1 (footnotes refer to sections within the 
protocol).

OBJECTIVE 
The objective of this study is to evaluate the safety and efficacy of a high and low dose of 
BOTOX versus placebo in the treatment of participants with moderate to severe platysma 
prominence. See Section 3 of the protocol for additional details. 
6.0 
PARTICIPANT POPULATIONS 
6.1 
MODIFIED INTENT-TO-TREAT POPULATION 
The modified intent-to-treat (mITT) population will consist of all randomized participants 
who had at least 1 post-baseline assessment of the primary efficacy parameter, the 
C-APPS, as described in the protocol. 
6.2 
SAFETY POPULATION 
The safety population will consist of all participants who were administered study 
intervention. 
7.0 
PARTICIPANT DISPOSITION 
The number of participants in the 2 study populations (safety and mITT) will be 
summarized by study intervention and overall. 
The number of participants screened will be summarized overall. The number and 
percentage of participants who were randomized, who were treated, who completed the 
study or who prematurely discontinued will be presented for each study intervention 
group and pooled across study intervention groups for all screened participants. The 
reasons for discontinuation will also be summarized (number and percentage). 
8.0 
DEMOGRAPHICS AND OTHER BASELINE CHARACTERISTICS 
Demographic parameters (age; 
 race; 
ethnicity; sex), and baseline characteristics (weight; height; 
 
 C-APPS grade; P-APPS grade; Fitzpatrick Skin Phototype) 
will be summarized descriptively by study intervention group for the mITT population. 
Continuous variables will be summarized by number of participants, mean, standard 
deviation (SD), median, minimum, and maximum values. Categorical variables will be 
summarized by number and percentage of participants. 
Participants’ medical and surgical histories will be coded using the Medical Dictionary 
for Regulatory Activities (MedDRA), version 23.0 or newer. The number and percentage 
of participants with medical and surgical histories ongoing at screening will be

• Alternative hypothesis: BOTOX and placebo are not equally effective in the 
probability of achieving ≥ 1-grade improvement in the C-APPS score 
 
 from baseline at Day 14. 
The following set of hypotheses will be used to compare the BOTOX groups with 
placebo for the secondary endpoint analysis: 
• Null hypothesis: BOTOX and placebo are equally effective in the probability of 
achieving ≥ 1-grade improvement in the P-APPS score 
 from 
baseline at Day 14. 
• Alternative hypothesis: BOTOX and placebo are not equally effective in the 
probability of achieving ≥ 1-grade improvement in the P-APPS score 
 
 from baseline at Day 14. 
For the primary endpoint analysis, the Cochran-Mantel Haenszel (CMH) test will be used 
to evaluate the equality of responder proportions of C-APPS between study intervention 
groups. 
 
 
 The BOTOX high dose group will be compared to the placebo group, and the 
BOTOX low dose group will be compared to the placebo group using a gate-keeping 
strategy (Dmitrienko 2005). If the comparison of the BOTOX high dose group versus the 
placebo group yields a p-value at the 0.05 significance level, the BOTOX low dose group 
will then be compared with the placebo group at the same 0.05 significance level. 
Otherwise, the BOTOX low dose group will not be considered statistically significantly 
superior to the placebo group, regardless of its p-value. (see Section 11.3.) 
Similarly, for the secondary endpoint analysis, the statistical comparisons will be 
conducted for the P-APPS. 
All statistical tests will be 2-sided hypothesis tests performed at the 0.05 level of 
significance for main effects. Wald confidence intervals for proportions of responders 
and difference in the proportion of responders will also be presented. All confidence 
intervals will be 2-sided 95% confidence intervals. 
Continuous descriptive statistics include the following: the numbers of participants with 
non-missing values at both baseline and the specified post-baseline analysis visit, mean, 
SD, median, minimum, and maximum. 
Categorical variables will be summarized by number and percentage of participants. 
Efficacy analyses will be performed for all visits. The primary analysis timepoint is 
Day 14.

11.1 
PRIMARY EFFICACY ENDPOINTS 
The primary efficacy endpoint will be achievement of a ≥ 1-grade C-APPS improvement 
from baseline 
 on Day 14. 
 
 
 
 
The evaluation of the equality of the proportions of responders will be based on the CMH 
test 
 
11.2 
SECONDARY EFFICACY ENDPOINTS 
The secondary efficacy endpoint will be achievement of ≥ 1-grade P-APPS improvement 
from baseline 
 on Day 14, as rated at maximum contraction 
by the participant using the P-APPS. 
11.3 
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 of the BOTOX groups versus 
placebo. The overall serial gatekeeping multiple comparisons procedure (MCP) is 
defined as follows: 
Table 11-1 
Multiple Comparisons Procedure 
MCP

3 
C-APPS responder (BOTOX low dose vs placebo) 
Nominal p-value ≤ α 
4

Categorical and continuous descriptive statistics, including change from baseline, will be 
presented for all visits for C-APPS and P-APPS scores. Continuous descriptive statistics 
will be provided for all visits 
 
 
 
 Methods for analyzing additional PRO endpoints 
aside from the P-APPS will be described and summarized in a separate analysis plan and 
report.

SAFETY ANALYSES 
The safety analyses will be performed using the safety population. The safety parameters 
will include adverse events (AEs) and vital signs. For vital signs, the last non-missing 
safety assessment before the first dose of study intervention will be used as the baseline. 
Continuous variables will be summarized by number of participants, mean, SD, median, 
minimum, and maximum values. Categorical variables will be summarized by number 
and percentage of participants. 
12.1 
ADVERSE EVENTS 
AEs will be coded by SOC and PT using MedDRA version 23.0 (or newer).

An AE will be considered a treatment-emergent adverse event (TEAE) if the AE began or 
worsened (increased in severity or became serious) on or after the date (and time, if 
known) of the first dose of study intervention. Per case report form instructions, a new 
AE record will be created with a new AE onset date for any AE that worsens. Therefore, 
TEAEs can simply be identified as those AEs with recorded onset date (and time, if 
known) on or after the date (and time) of intervention injection. 
Procedure-related AEs due to injection are identified as, but not limited to, the following: 
localized pain, inflammation, paresthesia, hypoesthesia, tenderness, swelling/edema, 
erythema, localized infection, bleeding, and/or bruising. In addition, needle-related pain 
and/or anxiety have resulted in vasovagal responses, including transient symptomatic 
hypotension and syncope. 
If more than 1 AE is coded to the same PT for the same participant, the participant will 
be counted only once for that PT using the greatest severity and strictest causality for the 
summarization by severity and causal relationship. An AE will be considered a serious 
TEAE if it is a TEAE that additionally meets any serious AE criteria. 
The total number and percentage of participants reporting AEs, TEAEs, treatment-related 
TEAEs (ie, study drug-related TEAEs, study procedure-related TEAEs), serious TEAEs, 
treatment-related serious TEAEs, deaths, AESIs, PDSOTs, and discontinuations due to 
TEAEs will be summarized for each study intervention group. 
The number and percentage of participants reporting TEAEs will be summarized in 
descending order by SOC and PT for each study intervention group. In addition, TEAEs 
will also be summarized in descending order by PT for each study intervention group. 
The number and percentage of participants reporting treatment-related TEAEs will be 
summarized in descending order by PT for each study intervention group. 
In addition, severity of TEAE will be summarized by PT for each study intervention 
group. 
For the safety population, separate listings will be presented for all AEs, participants who 
died, serious AEs (SAEs), AEs leading to study discontinuation, and pretreatment AEs 
(ie, AEs that occur after signing of the informed consent and prior to first dose of study 
medication).

DETERMINATION OF SAMPLE SIZE 
 
 
 
 
 
 
Approximately 165 participants will be enrolled in a 1:1:1 randomization allocation ratio, 
yielding approximately 55 participants in the BOTOX high dose group, 55 participants in 
the BOTOX low dose group, and 55 participants in the placebo group. With an 
anticipated attrition rate of approximately 10%, approximately 148 participants will be 
analyzable for the primary endpoint.

Relative to the date of the first dose of intervention. Day 1 is defined as the date of the first dose of study 
intervention. There is no Day 0 or Week 0. 
 
If the assessment date (if unavailable, use visit date instead) is on or after the date of the 
first dose of study intervention, the study day is calculated by (assessment date – date of 
the first dose of study intervention + 1). If the assessment date is before the date of the 
first dose of study intervention, the study day is calculated by (assessment date – date of 
the first dose of study intervention). Therefore, a negative day indicates a day before the 
start of the study intervention. 
If there are values from multiple visits in a given window, the value collected from the 
visit closest to the scheduled visit day will be used to represent the window. If two visits 
are equidistant from the scheduled visit day, the latter non-missing value will be used to 
represent the visit assessment. 
 
 
 
 
If multiple unscheduled visits occur on the same day, but no collection times are 
available, the most conservative (ie, worst) values will be used for each parameter 
separately.  
However, the P-APPS for the baseline analysis visit must be completed prior to or on 
Day 1; otherwise, the P-APPS for baseline/Day 1 visit will be considered missing.

REPEATED OR UNSCHEDULED ASSESSMENTS OF SAFETY 
PARAMETERS 
If a participant has repeated assessments before the first dose of study intervention, the 
results from the final non-missing assessment made prior to the start of the study 
intervention administration will be used as baseline. If end-of-study assessments are 
repeated or if unscheduled visits occur, the last non-missing postbaseline assessment will 
be used as the end-of-study assessment for generating summary statistics. All 
assessments will be presented in the data listings. 
16.3 
MISSING SEVERITY ASSESSMENT FOR ADVERSE EVENTS 
If severity is missing for an AE that started before the date of the first dose of study 
intervention, an intensity of mild will be assigned. If severity is missing for an AE that 
started on or after the date of the first dose of study intervention, an intensity of severe 
will be assigned. The imputed values for severity assessment will be used for the 
incidence summary; the values will be shown as missing in the data listings. 
16.4 
MISSING CAUSAL RELATIONSHIP TO STUDY TREATMENT 
FOR ADVERSE EVENTS 
If the causal relationship to the study intervention is missing for an AE that started on or 
after the date of the first dose of study intervention, a causality of yes will be assigned. 
The imputed values for causal relationship to study intervention will be used for the 
incidence summary; however, the values will be shown as missing in the data listings. 
16.5 
MISSING DATE INFORMATION FOR ADVERSE EVENTS 
Completely missing dates will not be imputed. 
The following imputation rules only apply to cases in which the start date for AEs is 
incomplete (ie, partly missing). 
Missing month and day 
• If the year of the incomplete start date is the same as the year of the first dose of 
study intervention, the month and day of the first dose of study intervention will 
be assigned to the missing fields 
• If the year of the incomplete start date is before the year of the first dose of study 
intervention, December 31 will be assigned to the missing fields 
• If the year of the incomplete start date is after the year of the first dose of study 
intervention, January 1 will be assigned to the missing fields

Missing month only 
• If only the month is missing, the day will be treated as missing and both the 
month and the day will be replaced according to the above procedure 
Missing day only 
• If the month and year of the incomplete start date are the same as the month and 
year of the first dose of study intervention, the day of the first dose of study 
intervention will be assigned to the missing day 
• If either the year of the incomplete start date is before the year of the date of the 
first dose of study intervention or if both years are the same but the month of the 
incomplete start date is before the month of the date of the first dose of study 
intervention, the last day of the month will be assigned to the missing day 
• If either the year of the incomplete start date is after the year of the date of the 
first dose of study intervention or if both years are the same but the month of the 
incomplete start date is after the month of the date of the first dose of study 
intervention, the first day of the month will be assigned to the missing day 
If the start date of the AE is the same as the start date of the study intervention 
administration, then assign the start time of the AE to be 1 minute after the stop time of 
the last dose of study intervention administration.  
If the stop date is complete and the imputed start date as above is after the stop date, the 
start date will be imputed by the stop date. 
If the start date is completely missing and the stop date is complete, the following 
algorithm will be used to impute the start date: 
• If the stop date is after the date of the first dose of study intervention, the date of 
the first dose of study intervention will be assigned to the missing start date 
• If the stop date is before the date of the first dose of study intervention, the stop 
date will be assigned to the missing start date 
Partially missing AE stop dates can follow the missing data methods in Section 16.6.2. 
16.6 
MISSING DATE INFORMATION FOR PRIOR OR 
CONCOMITANT MEDICATIONS OR PROCEDURES 
For prior or concomitant medications or procedures, including rescue medications, 
incomplete (ie, partly missing) start dates and/or stop dates will be imputed. When the 
start date and the stop date are both incomplete for a participant, the start date will be 
imputed first.

Incomplete Start Date 
The following rules will be applied to impute the missing numeric fields for an 
incomplete prior or concomitant medication or procedure start date. If the stop date is 
complete (or imputed) and the imputed start date is after the stop date, the start date will 
be imputed using the stop date.

16.6.2 
Incomplete Stop Date 
The following rules will be applied to impute the missing numeric fields for an 
incomplete prior or concomitant medication or procedure stop date. If the imputed stop 
date is before the start date (imputed or nonimputed start date), the imputed stop date will 
be equal to the start date.
