Introduction
Study Rationale
The purpose of this placebo-controlled, pivotal study is to evaluate the safety and efficacy of 
MT10109L for the treatment of GL in participants with moderate to severe GL 
 
Background
 
 
 
 
 
Glabellar lines are deep furrows or frown lines in the glabellar area of the face, and LCL (or 
CFL) are horizontal smile lines by the sides of the eyes. Both types of facial lines result from the 
repetitive functional action of the underlying mimetic facial musculature during animation 
(Blitzer 1993). When injected at therapeutic doses, MT10109L produces partial chemical 
denervation of the muscle, resulting in localized reduction in muscle activity. Because GL and 
LCL 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 remain because of 
constant muscle tone (Ferreira 2004; Garcia 1996).
The development of facial lines (such as GL and LCL) 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).

The popularity of BoNT/A cosmetic treatment of GL and LCL 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).
Benefit/Risk Assessment
Generally, the popularity of BoNT/A cosmetic treatment of GL and LCL 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, 
MT10109L provides additional benefits. For one, it is provided as a ready-to-use liquid product. 
Secondly, it is manufactured without human- or animal-derived products. MT10109L also offers

potential efficacy and safety advantages in addition to convenience since it does not require 
reconstitution and has shown sustained benefit in the treatment of GL.

The adverse drug reactions of eyelid ptosis, facial pain, facial paresis, and muscular weakness
usually are mild in severity, reversible, and have a low incidence. Therefore, no treatment for 
these reactions is recommended. If these reactions are moderate or severe, medical help should 
be sought as needed.
8.3.1
Time Period and Frequency for Collecting Adverse Event and Serious Adverse 
Event Information
For participants who received study intervention, all adverse events from the signing of the ICF 
until 30 days after the last study visit will be collected at the timepoints specified in the SoA
 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.
All SAEs from the signing of the ICF until at least 12 weeks after the last administration of study 
intervention will be collected at the timepoints specified in the SoA (Section 1.3), and as 
observed or reported spontaneously by study participants.
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 who received study intervention at subsequent visits/contacts. All TEAEs/SAEs, 
including AESIs
 will be followed until resolution, stabilization, the event is 
otherwise explained, or the participant is lost to follow-up 
.

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.
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 investigator’s brochure and will notify the IRB/IEC, if 
appropriate according to local requirements.
8.3.5
Pregnancy

Urine pregnancy testing will be conducted for women of childbearing potential prior to each 
study intervention, and at the study exit visit. See Appendix 7 for detailed information on 
definition of women of childbearing potential, use of contraceptives, and pregnancy.

To minimize the risk of pregnancy, all women of childbearing potential must agree to use a 
highly effective or acceptable contraception method (Appendix 7) consistently and correctly 
throughout the duration of the study. 

Women who test positive for urine pregnancy test will NOT receive further treatment and 
will be discontinued from the study.

Women who test positive for urine pregnancy test should complete end-of-study procedures 
and be followed up for pregnancy outcome.


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 abortion, fetal death, stillbirth, congenital 
anomalies, ectopic pregnancy) or genetic abnormalities (whether leading to an elective 
abortion or not) are considered SAEs.
 
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 or comparator as applicable. See Section 8.4 for information on the 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.
Treatment of Overdose
Overdose of MT10109L 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 MT10109L is administered as injections by physicians, for this study, the chance of 
overdose is extremely low. Should accidental injection or oral ingestion 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. For GL or LCL, eyelid ptosis, diplopia, and vision blurred are known local 
effects of the toxin. 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 educate the participant, monitor the course of 
overdose, contact the medical safety physician as needed, document the quantity of the excess 
dose, associated adverse events as well as the duration of the overdose in the eCRF.

Statistical Considerations
Statistical Hypotheses
For US FDA:
The primary efficacy analysis will be performed on the ITT population, which consists of all 
randomized participants. The following hypotheses will be used to compare MT10109L 20 U 
with placebo:

Null hypothesis: MT10109L 20 U and placebo are equally effective in reducing GL severity 
at maximum frown as measured by the proportion of responders with a ≥ 2-grade 
improvement from baseline based on both the investigator- and participant-rated FWS at 
Day 30.

Alternative hypothesis: MT10109L 20 U and placebo are not equally effective in reducing 
GL severity at maximum frown as measured by the proportion of responders with a 
≥2-grade improvement from baseline based on both the investigator- and participant-rated 
FWS at Day 30.

Primary Efficacy Endpoints
For the US FDA, the composite efficacy endpoints are the proportion of participants with a 
≥2-grade improvement from baseline on the FWS according to both investigator and participant 
assessments of GL severity at maximum frown at Day 30 using the ITT population after a single 
IM injection of MT10109L or placebo in the GL.
 
9.4.1.2
Primary Analyses
The primary efficacy analysis will be based on the comparison of GL efficacy for MT10109L 
20 U versus placebo at the primary timepoint of Day 30 of the first treatment period. The 
evaluation of the equality of the proportions of responders will be based on CMH test stratified 
by investigator-assessed baseline GL severity at maximum frown. Relative risk and 95% CI for 
relative risk will be presented. Missing values will be imputed up to Day 180 using multiple 
imputation methods. SAS Proc MI procedure will be used

Adverse Events
An adverse event will be considered a TEAE if:

The adverse event began on or after the date of the first dose of study intervention; or

The adverse event was present before the date of the first dose of study intervention, but 
increased in severity or became serious on or after the date of the first dose of study 
intervention
An adverse event that occurs more than 30 days after study exit 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.

Appendix 3: Adverse Events: Definitions and Procedures for 
Recording, Evaluating, Follow-up, and Reporting
Definition of AE
AE Definition

An AE is any untoward medical occurrence in a patient or clinical study participant, 
temporally associated with the use of study intervention, whether or not considered 
related to the study intervention.

An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease (new or exacerbated) temporally associated 
with the use of study intervention.
Events Meeting the AE Definition 

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) 
or other safety assessments (eg, ECGs, radiological scans, vital signs measurements), 
including those that worsen from baseline, considered clinically significant in the 
medical and scientific judgment of the investigator (ie, not related to progression of 
underlying disease); for example:
o
The test result is associated with accompanying symptoms, and/or
o
The test result requires additional diagnostic testing or medical/surgical 
intervention, and/or
Approval Date: 30-Sep-2020 22:56:38 (GMT)


CONFIDENTIAL
Protocol MT10109L-001 AMD 4
MT10109L
62
o
The test result leads to a change in study dosing (outside of any protocol-specified 
dose adjustments) or discontinuation from the study, significant additional 
concomitant drug treatment, or other therapy, and/or
o
The test result is considered to be an AE by the investigator or sponsor.

Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or intensity of the condition

New condition detected or diagnosed after study intervention administration even 
though it may have been present before the start of the study

Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction

Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
intervention or a concomitant medication. Overdose per se will not be reported as an 
AE or SAE unless it is an intentional overdose taken with possible 
suicidal/self-harming intent. Such overdoses should be reported regardless of 
sequelae.

Lack of efficacy or failure of expected pharmacological action per se will not be 
reported as an AE or SAE. Such instances will be captured in the efficacy 
assessments. However, the signs, symptoms, and/or clinical sequelae resulting from 
lack of efficacy will be reported as AEs or SAEs if they fulfil the definition of an AE 
or SAE.
Events NOT Meeting the AE Definition

Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments that are associated with the underlying disease, unless judged by the 
investigator to be more severe than expected for the participant’s condition. Merely 
repeating an abnormal test, in the absence of any of the above conditions, does not 
constitute an AE. Any abnormal test result that is determined to be an error does not 
require recording as an AE.

The disease/disorder being studied or expected progression, signs, or symptoms 
(clearly defined) of the disease/disorder being studied, unless more severe than 
expected for the participant’s condition

Medical or surgical procedure (eg, endoscopy, appendectomy): the condition that 
leads to the procedure is the AE

Situations in which an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital)
Approval Date: 30-Sep-2020 22:56:38 (GMT)


CONFIDENTIAL
Protocol MT10109L-001 AMD 4
MT10109L
63

Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present 
or detected at the start of the study that do not worsen
Definition of SAE
SAEs must meet both the AE criteria described above and the seriousness criteria listed below.
An SAE is defined as any untoward medical occurrence that, at any dose:
a.
Results in death
b.
Is life threatening
The term life threatening in the definition of serious refers to an event in which the 
participant was at risk of death at the time of the event. It does not refer to an event, 
which hypothetically might have caused death, if it were more severe.
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
Approval Date: 30-Sep-2020 22:56:38 (GMT)


CONFIDENTIAL
Protocol MT10109L-001 AMD 4
MT10109L
64
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.
Recording and Follow-Up of AEs and/or SAEs
AE and SAE Recording

When an AE or SAE occurs, it is the responsibility of the investigator to review all
documentation (eg, hospital progress notes, laboratory reports, and diagnostics 
reports) related to the event.

The investigator will then record all relevant AE or SAE information in the eCRF.

It is not acceptable for the investigator to send photocopies of the participant’s 
medical records to the sponsor in lieu of completion of the AE or SAE eCRF page.

There may be instances when copies of medical records for certain cases are 
requested by the sponsor. In this case, all participant identifiers, with the exception 
of the participant number, will be redacted on the copies of the medical records 
before submission to the sponsor.

The investigator will attempt to establish a diagnosis of the event based on signs, 
symptoms, and/or other clinical information. Whenever possible, the diagnosis (not 
the individual signs/symptoms) will be documented as the AE/SAE.
Approval Date: 30-Sep-2020 22:56:38 (GMT)


CONFIDENTIAL
Protocol MT10109L-001 AMD 4
MT10109L
65
Assessment of Intensity
MILD
A type of adverse event that is usually transient and may require only minimal 
treatment or therapeutic intervention. The event does not generally interfere 
with usual activities of daily living.
MODERATE
A type of adverse event that is usually alleviated with additional specific 
therapeutic intervention. The event interferes with usual activities of daily 
living, causing discomfort but poses no significant or permanent risk of harm 
to the research participant.
SEVERE
A type of adverse event that interrupts usual activities of daily living, or 
significantly affects clinical status, or may require intensive therapeutic 
intervention.
An event is defined as serious when it meets at least one of the predefined outcomes as 
described in the definition of an SAE, NOT when it is rated as severe.
Assessment of Causality

The investigator is obligated to assess the relationship between study intervention
and each occurrence of each AE or SAE.

A reasonable possibility of a relationship conveys that there are facts, evidence, 
and/or arguments to suggest a causal relationship, rather than a relationship cannot 
be ruled out.

The investigator will use clinical judgment to determine the relationship.

Alternative causes, such as underlying disease(s), concomitant therapy, and other 
risk factors, as well as the temporal relationship of the event to study intervention
administration will be considered and investigated.

The investigator will also consult the IB and/or product information, for marketed 
products, in his/her assessment.

For each AE or SAE, the investigator must document in the medical notes that 
he/she has reviewed the AE or SAE and has provided an assessment of causality.

There may be situations in which an SAE has occurred and the investigator has 
minimal information to include in the initial report to the sponsor. However, it is 
very important that the investigator always make an assessment of causality for 
every event before the initial transmission of the SAE data to the sponsor.

66

The investigator may change his/her opinion of causality in light of follow-up 
information and send an SAE follow-up report with the updated causality 
assessment.

The causality assessment is one of the criteria used when determining regulatory 
reporting requirements.
Reporting of SAEs
SAE Reporting
 

In rare circumstances and in the absence of facsimile equipment, notification by 
telephone is acceptable with a copy of the SAE form, sent by overnight mail or 
courier service.

Initial notification via telephone does not replace the need for the investigator to 
complete and sign the SAE form within the designated reporting time frames.

DEMOGRAPHICS AND OTHER BASELINE CHARACTERISTICS
Demographic parameters and baseline characteristics will be summarized by treatment group for 
ITT 
.  Continuous variables will be summarized by number of participants 
and mean, SD, median, minimum, and maximum values. Categorical variables will be 
summarized by number and percentage of participants.
Demographic parameters include age, age group (< 65 and ≥ 65), race, ethnicity and sex.  
Baseline characteristics include weight, height, body mass index (BMI, calculated as weight 
[kg]/ height[m]2), FWS scores of GL severity at maximum frown and at rest (assessed by 
investigators and participants), 
 
. The distribution of the baseline characteristics will be summarized 
by treatment group. 
The number and percentage of participants with abnormalities in medical and surgical histories 
in each system organ class (SOC) and preferred term (PT) will be summarized by treatment 
group for the ITT population.
Prior medications include all medications taken any time prior to the Day 1 baseline visit, 
whether or not medication is continuing beyond the Baseline Visit. 
Concomitant medications encompass all medicinal products that the participant was taking prior 
to the Day 1 baseline visit which are ongoing at the visit, in addition to all medications that have 
a start date on or after the Day 1 visit date. 
WHODrug 
will be used to classify prior and concomitant medications by 
therapeutic class and drug name.
Both prior and concomitant medications will be coded by drug name and therapeutic class. The 
use of prior and concomitant medications will be summarized by drug class and drug name in 
each treatment group for the ITT population.

MT10109L-001 Statistical Analysis Plan Amendment 1
The following hypothesis will be used to compare the MT10109L groups with placebo:

Null hypothesis:  MT10109L 20 U and placebo are equally effective in reducing GL 
severity at maximum frown as measured by the proportion of responders with a ≥2-grade 
improvement from baseline based on both the investigator- and participant-rated FWS at 
Day 30 of Treatment Cycle 1.

Alternative hypothesis:  MT10109L 20 U and placebo are not equally effective in 
reducing GL severity at maximum frown as measured by the proportion of responders 
with a ≥2-grade improvement from baseline based on both the investigator- and 
participant-rated FWS at Day 30 of Treatment Cycle 1.

CLINICAL LABORATORY EVALUATIONS
Hematology and non-fasting blood chemistry assays will be collected at screening visit only and 
performed by a central laboratory. The clinical laboratory parameters include the following:
Hematology:
Hemoglobin, hematocrit, red blood cell count (RBC), RBC morphology, 
white blood cell count (WBC), neutrophils, lymphocytes, monocytes, 
basophils, eosonophils, and platelets

DATA HANDLING CONVENTIONS

The level of significance used for all statistical tests will be 0.05, 2-sided, unless stated 
otherwise. P-values ≤0.050 will be considered as statistically significant.
 

Descriptive statistics for continuous variables include the sample size (N), mean, standard 
deviation, median, minimum (min), and maximum (max).

Summary statistics for categorical variables include the sample size (N), frequency count, 
and percent.
 
 

The Medical Dictionary for Regulatory Activities (MedDRA) will be used to code all adverse 
events (AEs) and medical history.

World Health Organization Drug Dictionary Enhanced (WHO DDE) preferred name and 
MedDRA will be used to code all medications.

REPEATED OR UNSCHEDULED ASSESSMENTS OF SAFETY 
PARAMETERS
If a participant has repeated assessments before the start of the first treatment, the results from 
the final nonmissing assessment made prior to the start of the study intervention will be used as 
baseline. If end-of-study assessments are repeated or if unscheduled visits occur, the last 
nonmissing postbaseline assessment will be used as the end-of-study assessment for generating 
summary statistics.

15.6
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.
15.7
MISSING CAUSAL RELATIONSHIP TO STUDY INTERVENTION 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; the 
values will be shown as missing in the data listings.
15.8
MISSING DATE INFORMATION FOR ADVERSE EVENTS
Partial adverse event onset date will be imputed as follows:  1) if day is missing but month is not, 
impute the date as the first day of the month; 2) if both day and month are missing, impute the 
date as 01 Jan; 3) if imputed onset date is before the first treatment, yet the corresponding 
adverse event was not observed pre-treatment, then impute the onset date as the first treatment 
date.  Imputed partial adverse event onset date will only be used to determine the adverse event 
onset cycle.  
Other partial adverse event dates will not be imputed.  All partial dates will be listed “as is” in 
the data listings.
15.9
MISSING DATE INFORMATION FOR PRIOR OR CONCOMITANT 
MEDICATIONS
There will be no imputation for missing or partially reported medication start and/or end dates. 
However, reported partial information will be utilized in classification of prior and concomitant 
medications, when appropriate. For example, a medication may be classified as a pre-study 
medication if the partial end date provided is determined to definitively have occurred prior to 
the study intervention date (for example, the partial end date provided is “2017”, and Day 1 
occurred on August 29, 2018).
If start and/or stop dates for medications are only partially reported but can be classified as 
having occurred prior to Day 1, then the medications will be included in this summary of prior 
medications.
If stop dates for medications are only partially reported and cannot be definitively classified as 
having occurred prior to Day 1, then the medications will be included in this summary of 
concomitant medications.
