INTRODUCTION 
This descriptive study is intended to provide feedback from participants about their 
experience using the lebrikizumab pen when delivering a simulated injection into an injection 
pad. The participant’s experience will be evaluated based on their responses to the modified 
Subcutaneous Administration Assessment Questionnaire (mSQAAQ), a PRO questionnaire 
for evaluating one’s experience (e.g., ease of use and confidence in using) with a device to 
administer a SC injection.9,10 
 
Participants will perform a simulated injection and provide their feedback on the experience.  
The participants will perform the tasks independently after training by the study team. Since 
there is active drug in the pen, the site staff will remain in the room with the participant 
during their simulated injection into the injection pad. After the simulated injection, a trained 
study site staff will distribute the mSQAAQ for the participant to complete independently 
onsite.

BACKGROUND   
5.1 
Description of the Drug Product 
Lebrikizumab (LY3650150) is an IgG4 mAb that binds with high affinity and slow off-rate 
to IL-13 and selectively inhibits IL-13 signaling through the IL-4Rα/IL-13Rα1 pathway, 
thereby blocking the downstream effects of IL-13 with high potency. Lebrikizumab-bound 
IL-13 can still bind IL-13Rα2, allowing subsequent internalization and natural clearance of 
IL-13. Blockade of IL-13 signaling is expected to be of benefit in diseases in which IL-13 is 
a central cytokine to the disease pathogenesis, such as atopic dermatitis (AD). 
Lebrikizumab has been investigated for the treatment of AD, asthma, COPD, IPF, and RHL. 
Currently, lebrikizumab is being actively developed for the treatment of AD. Lebrikizumab is 
also being investigated for the treatment of perennial allergic rhinitis (PAR) and chronic 
rhinosinusitis with nasal polyps (CRSwNP). 
An Investigator’s Brochure for the drug provides a summary of the clinical studies conducted 
for lebrikizumab and the associated findings.  
5.2 
Description of the Investigational Device  
The lebrikizumab pen has a drug product container assembled inside the pen (Figure 1). The 
combined container and pen form a prefilled, single-use, injection device that delivers a fixed 
dose of drug product subcutaneously. The drug will remain in the container until the drug is 
injected. The pen uses a fixed needle injection depth that is inserted perpendicular to the skin 
without the need to raise a skinfold (i.e., a flat-surface injection) to deliver an SC injection. 
 
To facilitate understanding of the operation of the pen, refer to Figure 1 and the J2T-MC-
KGBY instructions for use (IFU). Further guidance and information for the final disposition 
of unused study interventions are provided in the Pharmacy Manual7 and Dose Preparation 
Instructions8. 
 
The solution in the pen requires storage under refrigerated conditions (2oC to 8oC). Prior to 
use, the pen is removed from the refrigerator and allowed to warm to room temperature for 
45 minutes. The pen can remain at room temperature for up to 8 hours. If the pen is not used 
within the allowed timeframe, it should be returned to refrigerated conditions and the 
temperature excursion process should be followed. Further guidance on the excursion process 
is provided in the Pharmacy Manual7.  
 
The pen is prepared by removing the Twist-off Cap that pulls the syringe needle shield off. 
The pen base is placed flat and firmly onto the patient’s skin at the injection site. The base of 
the device helps to orient the needle perpendicular to the skin. After placement on the skin,

the device is unlocked by turning the Lock Ring to align the raised plastic feature (lock 
indicator) to the Unlock Symbol. The device can be activated only when the lock indicator is 
aligned with the Unlock Symbol. The user activates the device by pressing the Injection 
Button. This generates an audible and tactile click and the device automatically performs the 
following steps: 
 
1. Inserts needle into the skin 
2. Injects the solution 
3. Delays needle retraction to ensure complete delivery 
4. Retracts the needle. 
 
The user must hold the device firmly against the skin during the injection cycle but is not 
required to maintain pressure on the Injection Button. The device generates an audible and 
tactile click at the end of the needle retraction process. The device locks the retracted needle 
in place for disposal of the used pen into a sharp container. 
 
The pen was developed according to the requirements established by the ISO and standards 
for needle-based injection systems for medical use (ISO 11608-1 and ISO 11608-5). An 
Investigator’s Brochure for the device outlines the testing and associated findings for the 
device.

Intended Participant Environment 
The participant environment will be non-clinical and emulate the noise, lighting, and 
surroundings of a home environment.  In order to observe the participants, the rooms are 
equipped with 1-way mirrors, cameras, and remote monitoring equipment.   
5.4 
Rationale for Study Design 
Autoinjectors (AI) and prefilled syringes (PFS) are commonly accepted as safe and effective 
for their intended use. Thus, the development of the AI to deliver lebrikizumab is based on 
the evidence of benefit, as observed in similar approved AIs. Whereas other commercially 
available AIs are designed to deliver 1 mL of the drug product, the lebrikizumab AI is 
designed to deliver 2 mL of the study drug. The 2-mL AI has been used in the lebrikizumab 
clinical development program in Studies J2T-DM-KGAA (KGAA) and J2T-MC-KGBG 
(KGBG).4  The results of these studies demonstrate that the 2-mL AI is a viable device for 
the SC administration of lebrikizumab. The 2-mL AI for delivering lebrikizumab will be 
referred to as the lebrikizumab pen for the purposes of this study. 
The study design for the current ease of use study is descriptive in nature (51 participants) 
and intended to provide relevant information about the participant experience with the 
lebrikizumab pen. The population will be comprised of individuals with AD with no prior AI 
or pen experience, although those with experience with other injectables will be permitted.  
Evaluation of the participant’s experience will be based on the mSQAAQ9,10, an instrument 
for assessing ease of use and confidence in use of a subcutaneous device.    
5.5 
Study Benefit and Risk Assessment 
While there are no direct therapeutic benefits to participants participating in this study, the 
results from this study will offer valuable insights into the participant’s experience with the 
lebrikizumab pen as related to ease of use and confidence in injection. The risks associated 
with participation in this study will be minimized because the simulated injections will be 
performed into injection pads and participants will be under the direct supervision of study 
staff when handling the injection devices. Participants are not injecting themselves in this 
study.  
5.6 
 Risks and Foreseeable Adverse Events/Device Effects  
The following is a list of potential risks associated with participation in this study:  
• 
Accidental needle stick injury  
• 
Accidental exposure to drug product (accidental self-injection)

• 
Injection site reaction or hypersensitivity event associated with exposure to drug 
product via accidental injection  
The following is a list of potential risks associated with the study devices:  
• 
Improper functioning and/or mechanical failure of the device or its components (for 
example, no injection, slow injection into injection pad, partial injection into injection 
pad, cracked syringes, high force to operate device, damaged needle)  
• 
Skin reaction due to exposure of drug product on skin   
5.7 
Methods to Minimize Risks  
Training on the study device will be provided by study staff prior to the participant 
performing the simulated injection. Training for correct sharps handling/disposal is part of 
the study training, and no cross contamination is expected due to each participant receiving 
their own device, as well as injecting drug into an injection pad. Participants will be 
instructed to place the base cap in the sharps container once it is removed from the device, so 
they do not have the temptation to recap. Study staff will monitor the participants at all times 
in the room and intervene should a dangerous situation occur.  
Participants will be under direct supervision of the study staff when handling the device.   
The following controls will be in place to prevent an accidental dose of drug product:  
1. The participants will only handle the devices under direct supervision of study staff 
after receiving training.  
2. Participants will be told that they should not inject themselves, and these devices will 
only be used for simulated injections into an injection pad.  
3. If a participant appears to begin injecting themselves rather than the injection pad, the 
site staff will immediately interrupt the process and stop the participant from 
completing this self-injection.  
4. In the unlikely circumstance that a participant does have an accidental needle stick or 
accidental injection, it is not likely the participant would receive a full dose since a 
full dose takes up to 15 seconds for delivery.    
If a needlestick injury occurs or if a patient is exposed to drug, medical personnel will be 
available to address any potential medical issues or concerns. Clinical staff members will 
follow (monitor) the participant as per clinical judgment for a potential adverse event (AE) 
and follow the appropriate device-reporting procedures for 7 days following the visit.  
 More detailed information about the known and expected benefits and risks of lebrikizumab 
may be found in the lebrikizumab investigator’s brochure (IB)3.

DESCRIPTION OF DESIGN AND TRIAL POPULATION 
6.1 
Overall Trial and Design and Plan 
This study is an open-label, single site, ease of use study of the lebrikizumab pen and consists 
of a single study visit for approximately 56 adult participants. All participants will receive 
training and perform simulated injections on a practice pad using the pen.  Participants will 
be under the supervision of a study interviewer when handling the pen and will complete the 
mSQAAQ9,10 following the simulated injection.  
No treatment will be administered to the participants. 
6.2 
Administrative Structure of the Trial 
This is an ease-of-use study (with a simulated injection) with a planned analysis population 
of 51 participants. The participant will be taken to a non-clinical observation room equipped 
with a 1-way mirror and cameras. The setting is a non-clinical setting arranged similar to a 
home environment with similar lighting and sound.  
The participant will be given training on the use of the pen and then given an opportunity to 
simulate administration of a dose into an injection pad. Following the injection experience, 
the participant will self-administer the mSQAAQ9,10.  
6.3 
Selection of Participant Population 
The participants will be recruited from the site database. A log of all participants enrolled 
into the study (i.e. having signed the Informed Consent Form) will be maintained by the 
research site. Minimal personal health information (PHI) will be gathered which will include  
the approximate date of their AD diagnosis, any previous or current treatments, any known 
experience with administering drugs by injection to self or others, and if the individual is of 
child-bearing potential (see Section 9.2.1) , they will be tested to rule out pregnancy given 
the risk of accidental exposure to drug.  
Individuals who self-report having been diagnosed with AD will be pre-screened by phone 
based on the inclusion and exclusion criteria. Those who qualify (i.e. inclusion criteria apply, 
and exclusion criteria do not apply) will be scheduled for a 1-visit study at the research site. 
The enrolled study population of approximately N=56 will be comprised of adults, ages 18 
and older. 
While there will be no other assigned quota groups, additional characteristics of the study 
population will be diverse and may include age, gender, education, literacy, or other patient 
characteristics.

The REALM test2 will be given to all enrolled individuals to identify participant health 
literacy levels.  The REALM is based on a list of 66 words, which participants are asked to 
read out loud.  The number of correctly pronounced words is noted on a scoring sheet.  Those 
scoring 61 and above are categorized as having normal literacy and those scoring 60 or 
below as having limited literacy.  Scores of 60 or lower correspond to a 7-8th grade reading 
level or lower (See Table 1).

This study will require one visit. Participants will be enrolled and completed at Visit 1. A 
Study Flowchart can be found in Figure 2 and a Schedule of Events is located in Table 2. 
9.2 
Details of Study Procedures  
9.2.1 
Recruitment and Pre-Screening 
Participants will be recruited by the research site who will access their site database 
comprised individuals who have participated in previous studies and/or expressed interest in 
participating in future studies.  Potential participants will be pre-screened by phone with the 
inclusion and exclusion criteria including any previous pen experience.  Participants who 
qualify (i.e. inclusion criteria apply, and exclusion criteria do not apply) will be referred to 
the research site.   
9.2.2 
Visit 1 
This is a single center, single visit simulated use study.  All participants will be completed at 
the end of Visit 1.  There is no treatment period; this study involves a simulated injection 
with a pen device into an injection pad followed by a self-administered questionnaire 
(mSQAAQ)9,10 about the participant’s experience.  
9.2.3 
Enrollment and Visit 1 Activities 
Participants arriving at the research site will be given an informed consent document to read 
and sign. The participant will be given an opportunity to ask any questions and will be 
reminded that participation is voluntary and that the option exists to withdraw at any time. 
Inclusion and exclusion criteria will be re-confirmed as well as demographic information and 
previous pen experience; for this study, all participants are required to be pen and AI naïve 
(i.e., no prior experience with a pen or AI). 
Participants who were assigned female at birth (AFAB) will be asked to take a urine 
pregnancy test to confirm they are not pregnant. Individuals not of childbearing potential 
(INOCBP) will be exempt from a urine pregnancy test. Individuals AFAB are considered 
INOCBP if they are not capable of producing ova or embryo, and/or are not capable of 
potentially gestating a fetus. Such individuals include those who have a congenital anomaly 
such as Müllerian agenesis resulting in confirmed infertility, are infertile due to surgical 
sterilization, or are menopausal. Acceptable surgical sterilization methods are hysterectomy, 
bilateral salpingo-oophorectomy, bilateral salpingectomy, or bilateral oophorectomy.

The Rapid Estimate of Adult Literacy in Medicine (REALM)2 test will be administered to 
assess health literacy. A brief medical history will be conducted to gather information about 
the approximate date of participants’ AD diagnosis and any previous or current AD 
treatments. No laboratory assessments will be required, and no samples will be taken from 
study participants. Participants will then be given a brief study overview about the nature of 
the study in which they will simulate use of the pen into an injection pad.  
9.2.4 
Device Training 
Training will be provided to participants in advance of the simulated injection.  This training 
will be in the form of a clinical study training video describing parts of the lebrikizumab pen, 
pen operation instructions, and a demonstration of dose delivery into an injection pad.  Study 
staff will also provide additional training and guidance such as introducing study materials to 
the participant, directing participant to review the IFU, assisting with attachment of the 
injection pad, and providing the mSQAAQ9,10 following injection simulation. Participants 
will be allowed to ask questions on training instructions to site staff during training. 
9.2.5 
Simulated Injection 
Participants will be provided with IFU (Appendix 14.1), an injection pad and a pen device.  
The pen device will be taken out of the refrigerator at least 45 minutes prior to the 
simulation.  The injection pad will be placed on the participant’s thigh or abdomen, based on 
their preference. Participants will be directed to simulate an injection using the pen device by 
injecting directly into the injection pad. 
The pen device contains active drug.  Should a participant inadvertently stick themselves 
with the needle, follow-up care will be provided and an Adverse Event CRF and Product 
Complaint Form (if applicable) will be completed. Devices involved in product complaints or 
adverse events will need to be labeled and stored by site for future investigation by the 
Sponsor.   Adverse events will be gathered from the point that the informed consent is signed 
until participant leaves site on date of visit. Participants with adverse events during the Visit 
will be followed for 7-days post visit (See Section 12). 
9.2.6 
mSQAAQ 
After the simulated injection, participants will be provided with a self-administered 
questionnaire, the mSQAAQ to complete.9,10 After the mSQAAQ is completed, the visit will 
be completed.

10 DATA COLLECTION, MANAGEMENT, AND ANALYSIS 
10.1 Data Collection 
Case Report Form (CRF) data will be collected using a 21 CFR Part 11 compliant electronic 
data capture system (EDC), the IQVIA Research Management Platform (RMP) v2.6. Data 
from recruitment and pre-screening will be captured separately and not entered into the RMP 
EDC system. Since the study is being conducted in person, a paper informed consent and a 
paper 24-hour SAE report form will be used.  
CRF data will include: 
• Confirmation of inclusion and exclusion criteria 
• Participant demographics 
• REALM2 score 
• Confirmation of pen/AI experience (i.e., pen/AI naïve, any other experience with 
injectables) 
• Pregnancy test results for participants AFAB unless considered INOCBP  
• Brief medical history (approximate date of AD diagnosis and previous or current 
treatments) 
• Responses to the 10 questions in the mSQAAQ9,10 
• Adverse events (AE) 
• Serious adverse events (SAE) 
10.2 Sample Size 
The planned final sample size of 51 is sufficient to provide descriptive insights about the 
study population. Given the nature of the study it is expected that 
%+ of participants 
enrolled will complete the study and provide full analyzable data.  
 
Under the assumption that 
% of the participants will respond “agreed” or “strongly 
agreed” to the device being “easy to use” and “they are confident they can use the device” we 
will have 95% confidence that the response rate is located in this range of proportions: [
% 
- 
%]. Table 3 shows a variety of possible sample sizes. For the purpose of the intended 
claims the 95% CI lower bound should remain above 
%, preferably above 
%, and the 
parameters for the calculation of sample size have been selected for that.

10.3 Data Management & Statistical Analysis 
10.3.1 
Data Analysis 
A descriptive analysis will be conducted to assess the ease of use and confidence of use of the 
lebrikizumab pen. All participants having given an informed consent will be included in the 
analysis population. 
The main endpoint of the study will be assessed via the mSQAAQ9,10. The primary outcome 
reported from each individual question will be the proportion of participants responding 
“agreed” or “strongly agreed” to the question. Participants who do not complete an individual 
item in the mSQAAQ will have their remaining questions analyzed per instrument instructions.  
Collected demographic information and health literacy level of study participants will be 
presented for the total analysis population as well as any selected sub-populations. A 
descriptive analysis of any AEs and/or product complaints reported during the study will be 
included for the total analysis population.

Practices (GCP). Study site supervisory staff will be trained regarding all study procedures, 
including, quality control, CRFs, mSQAAQ, 9,10 documentation and communication with the 
CRO.  
Quality checks will be performed by the data management team at Concentrics Research on 
all data collected to ensure completeness, accuracy and consistency of the data captured (e.g. 
all required fields are completed, follow-up questions were asked where appropriate). Any 
discrepancies or questions with respect to the data will be handled via queries sent to the 
research site for clarification and/or resolution.    
10.4 Interim Analysis 
There is no plan to perform interim analyses for this study.  
10.5 Handling of Missing Data 
Any participants who attend a study visit but do not complete the simulated injection and 
mSQAAQ9,10 will be excluded from the analysis. Partial completion of the mSQAAQ will be 
analyzed per the instrument instructions.

11 Monitoring 
Risk-based monitoring will be conducted for this study. The pre-study visit has been waived 
by the CRO.  
The Site Initiation Visit will be combined with a virtual Investigator’s Meeting. During this 
meeting the study protocol, objectives, methods, data collection and data entry procedures 
and adverse event procedures will be reviewed. 
During the course of the study there will be 3 interim monitoring visits. Some visits will be 
on-site, and some will be remote. The CRA will review the eCRFs and source documents and 
review Study Device accountability.  
One close-out visit is planned. At this visit, a final review of all documentation and data entry 
will be completed. Study Device accountability will be reviewed and the plan for Study 
Device return or destruction will be discussed.

12 Safety 
12.1 Adverse Event Definition 
An AE is defined as any untoward medical occurrence in a participant or clinical 
investigation (vital signs, physical change, etc.) that does not necessarily have a causal 
relationship with the treatment. An AE can be any unfavorable or unintended sign 
(including an abnormal finding on vital signs, physical change, etc.), symptom, or disease 
temporally associated with the use of an IP, whether or not related to the IP. 
This includes any adverse occurrence that is new in onset or aggravated in severity, duration, 
or frequency from the baseline condition (including the physical examination), or abnormal 
results of diagnostic procedures (including vital sign abnormalities). 
Examples of untoward medical events that should be considered AEs are those that: 
• resulted in discontinuation from the study, 
• required treatment or any other therapeutic intervention, 
• required further diagnostic evaluation (excluding a repetition of the same 
procedure to confirm the abnormality), 
• are associated with clinical signs or symptoms judged by the Investigator to 
have a significant clinical impact. 
Examples of what an AE is not: 
• A surgical procedure 
• A situation where an untoward event did not occur, (e.g. a social 
hospitalization) 
• The disease being studied, unless progression is more severe than anticipated 
•  Baseline conditions that have not worsened in severity or frequency 
• Abnormal findings or test results (unless considered clinically significant in the 
opinion of the investigator or specifically defined elsewhere in the protocol) 
related to the disease being studied (unless more severe than expected). 
12.2 Adverse Device Effect Definition 
An adverse device effect (ADE) is any adverse event related to the use of an investigational 
medical device (This definition includes adverse events resulting from insufficient or 
inadequate instructions for use, deployment, implantation, installation, or operation, or any 
malfunction of the investigational medical device. Includes any event resulting from use 
error or from intentional misuse of the investigational medical device. Also includes 
‘comparator’ if the comparator is a medical device.).

12.3 Procedures 
Adverse events will be gathered from the point that the informed consent is signed until 
participant leaves site on date of visit. Participants with unrelated adverse events will be 
followed for 7-days post AE. All SAEs, and related AEs will be followed until the event has 
resolved. This is a 1-visit study. 
A description of the event or diagnosis including dates, severity, relationship to the device 
and/or IP, action taken and outcome, and whether or not the event was also serious, must be 
reported on the AE Case Report Form (CRF) for each adverse event. 
12.4 Severity 
Adverse events are graded according to seriousness and severity. The seriousness of an event 
is determined by the regulatory criteria in Section 13.7.  
The Investigator will evaluate the severity of each AE. Adverse event severity will be graded 
as follows: 
Mild:   
Awareness of symptoms but easily tolerated  
Moderate: 
Discomfort enough to interfere with but not prevent daily activity 
Severe: 
Unable to perform usual activity 
12.5 Relationship 
The Investigator will judge the likelihood that the AE was related to the device or IP  
according to the following criteria: 
• Not related: There is no possible temporal and/or causal relationship to the 
device or IP 
• Related: There is a possible temporal and/or causal relationship to the device or 
IP  
12.6 Action Taken and Outcome 
 Action Taken with IP or device will not be collected given the nature of this study. The 
Outcome of each AE will be entered as either: Recovered/Resolved, Recovered/Resolved 
with Sequelae, Not Recovered/Not Resolved, Fatal, or Unknown. 
12.7 Adverse Event Follow-up 
Investigators will follow unrelated AEs until 7-days after the study visit. All SAEs, and 
related AEs will be followed until the event has resolved.

12.8 Serious Adverse Events 
An AE or ADE that results in any of the following outcomes is serious: 
• Death (note that death is the outcome of an SAE, and the cause of death should 
be listed as the AE) 
• Life-threatening event. An event, in the view of either the investigator or 
sponsor, which places the patient or participant at immediate risk of death. (It 
does not include an adverse event or suspected adverse reaction that, had it 
occurred in a more severe form, might have caused death) 
• In-patient hospitalization or prolongation of existing hospitalization 
• A persistent or significant incapacity, permanent damage or disability or 
substantial disruption of the ability to conduct normal life functions 
• Congenital anomaly or birth defect 
• Other important medical event that may not result in death, be life-threatening, 
or require hospitalization may be considered serious when, based upon 
appropriate medical judgment, it may jeopardize the participant or may require 
medical or surgical intervention to prevent one of the outcomes listed in this 
definition. 
• Hospitalization for elective surgery for a prior condition that did not worsen or 
for social reasons will not be treated as serious. 
A serious adverse device effect (SADE) is a serious event that has resulted in any of the 
consequences characteristic of a serious adverse event. For the purpose of this study, the term 
SAE will include SADEs. 
12.8.1 
Serious Adverse Event Reporting 
Any SAE which occurs after the Informed Consent document is signed until participant 
leaves site on date of visit must be reported to Lilly. Lilly must be notified within 24 hours 
after the site/investigator becomes aware of the SAE.  
If the Principal Investigator determines that the event is serious, the following procedures 
will be implemented: 
• The Investigator will report the SAE directly to Lilly. Contacts for SAE 
reporting can be found in site training materials. 
• Investigator will provide, at a minimum, the protocol number, participant’s 
initials, participant number, date of the SAE, SAE term and relationship to IP 
and/or device. The SAE report form should be submitted with any supporting 
data available or copies of CRF pages. 
• Advarra IRB will be notified of the SAE by the site within the timeframes 
described below: 

Protocol #23037/J2T-MC-KGBY 
 
 
 
12APR2024_v1.0

Concentrics Research,  
 
CONFIDENTIAL 
an IQVIA Business  
1. Unanticipated problems that are serious adverse events should be 
reported to the IRB within 10 business days of the investigator 
becoming aware of the event. 
2. Any other unanticipated problem should be reported to the IRB within 
10 business days of the investigator becoming aware of the problem. 
An initial report followed promptly by a complete report will be forwarded to Advarra IRB. 
12.8.2 
Serious Adverse Event Follow-up 
Investigators will follow all SAEs until the SAE has resolved. 
The Investigator and Medical Monitor will determine if additional follow-up is required. 
Follow-up information relating to an SAE must be submitted to Lilly as soon as additional 
data related to the event are available. All efforts must be taken to obtain follow-up 
information promptly. 
Follow-up information may consist of: 
• A hospital discharge summary for participants who are hospitalized or 
hospitalized over a prolonged period due to the SAE. If possible, the discharge 
summary should be obtained when it becomes available. 
• A copy of the autopsy report, if a death occurs and an autopsy is performed, 
should be obtained if possible when it becomes available. 
Any SAE that is ongoing at the end of visit 1 should be followed as described above. Data 
after visit 1 should be recorded on the source documents and submitted to Lilly on an SAE 
report form. For ongoing SAEs, the Principal Investigator must submit follow-up reports 
to Lilly regarding the participant’s subsequent course until the case is closed. 
12.9 Unexpected Adverse Event 
As defined by 21 CFR 312.32 (a), an unexpected adverse drug experience is:  
“An adverse event or suspected adverse reaction is considered “unexpected” if it is not 
listed in the investigator brochure or is not listed at the specificity or severity that has been 
observed; or, if an investigator brochure is not required or available, is not consistent with 
the risk information described in the general investigational plan or elsewhere in the 
current application, as amended. For example, under this definition, hepatic necrosis 
would be unexpected (by virtue of greater severity) if the investigator brochure referred 
only to elevated hepatic enzymes or hepatitis. Similarly, cerebral thromboembolism and 
cerebral vasculitis would be unexpected (by virtue of greater specificity) if the investigator 
brochure listed only cerebral vascular accidents. “Unexpected,” as used in this definition, 
also refers to adverse events or suspected adverse reactions that are mentioned in the 

Protocol #23037/J2T-MC-KGBY 
 
 
 
12APR2024_v1.0

Concentrics Research,  
 
CONFIDENTIAL 
an IQVIA Business  
investigator brochure as occurring with a class of drugs or as anticipated from the 
pharmacological properties of the drug but are not specifically mentioned as occurring 
with the particular drug under investigation.” 
The study sponsor will expedite reporting all serious unexpected suspected adverse 
reactions (SUSARs): initial reporting by the sponsor for nonfatal or non-life threatening 
SUSARs must be submitted as soon as possible but no later than within 15 calendar days 
following the sponsor’s initial receipt of the information, and for fatal or life-threatening 
SUSARs, initial reports must be submitted no later than 7 calendar days following the 
sponsor’s initial receipt of the information. Any relevant additional information obtained by 
the sponsor that pertains to a previously submitted IND safety report must be submitted as a 
Follow-up IND Safety Report without delay as soon as the information is available but no 
later than 15 calendar days after the sponsor receives the information. 
Such expedited reports will comply with the applicable regulatory requirements and with 
the FDA’s Guidance for Industry and Investigators Safety Reporting Requirements for 
INDs and BA/BE Studies (21 CFR 312.32). 
12.9.1 
Unanticipated Adverse Device Effect 
As defined by 21 CFR 812.3 (s), an unanticipated adverse device effect (UADE) is: 
"any serious adverse effect on health or safety or any life-threatening problem or death 
caused by, or associated with, a device, if that effect, problem, or death was not previously 
identified in nature, severity, or degree of incidence in the investigational plan or 
application (including a supplementary plan or application), or any other unanticipated 
serious problem associated with a device that relates to the rights, safety, or welfare of 
participants." 
The PI will report evaluation results for any unanticipated adverse device effect per 21 CFR 
812.150 (b)(1) within 10 days working days to the reviewing IRB(s). 
All unanticipated adverse device effects will be evaluated and reported as warranted within 
10 working days after sponsor first receives notice of the effect per 21 CFR 812.46 (b) and 
21 CFR 812.150 (b)(1). 
12.9.2 
Definition of Product Complaints  
A product complaint is any written, electronic, or oral communication that alleges 
deficiencies related to the identity, quality, durability, reliability, safety, effectiveness, or 
performance of a study intervention. When the ability to use the study intervention safely is 
impacted, the following are also product complaints: 
• deficiencies in labeling information 

Protocol #23037/J2T-MC-KGBY 
 
 
 
12APR2024_v1.0 
 37 
Concentrics Research,  
 
CONFIDENTIAL 
an IQVIA Business  
• use errors for device or drug-device combination products due to ergonomic 
design elements of the product. 
Product complaints related to study interventions used in clinical trials are collected to ensure 
the safety of participants, monitor quality, and to facilitate process and product 
improvements. 
If the participant identifies a product complaint or a problem with the study intervention, 
investigators will instruct participants to contact the site as soon as possible so that the 
situation can be assessed. 
An event may meet the definition of both a product complaint and an AE/SAE. In such cases, 
it should be reported as both a product complaint and as an AE/SAE. 
Device deficiencies are product complaints. 
12.9.3 
Recording and Follow-Up of AE and/or SAE and Product Complaints  
When an AE/SAE/product complaint occurs, it is the responsibility of the investigator to 
review all documentation (for example, hospital progress notes, laboratory reports, and 
diagnostics reports) related to the event. 
The investigator will then record all relevant AE/SAE/product complaint information in the 
participant’s medical records, in accordance with the investigator’s normal clinical practice. 
AE/SAE information is reported on the appropriate CRF page and product complaint 
information is reported on the Product Complaint Form. 
Note: An event may meet the definition of both a product complaint and an AE/SAE. In such 
cases, it should be reported as both a product complaint and as an AE/SAE. 
It is not acceptable for the investigator to send photocopies of the participant’s medical 
records to the sponsor or designee in lieu of completion of the CRF page for AE/SAE and the 
Product Complaint Form for product complaints. 
There may be instances when copies of medical records for certain cases are requested by the 
sponsor or designee. 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 or designee. 
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.

13 INVESTIGATOR OBLIGATIONS 
13.1 Ethical and Regulatory Considerations 
This study will be conducted in accordance with Good Clinical Practice (GCP) Guidelines 
E6 (2)5  and the Code of Federal Regulations ( Title 21 CFR Parts 11, 50, 54, and 56).6 
13.2 Institutional Review Board 
The Concentrics Research will ensure that an appropriately constituted Institutional Review 
Board (IRB), in compliance with the requirements of 21 CFR 56, reviews and approves the 
clinical study before the study is initiated. IRB approval must refer to the study by exact 
protocol title, number, and amendment number (if applicable), identify the documents 
reviewed, and state the date of review. 
Concentrics Research will ensure that Lilly approves any changes to the Informed Consent 
template prior to submission to the IRB. 
Should changes to the Informed Consent document become necessary during the study, 
Concentrics Research will ensure that the changes are approved by Lilly prior to submission 
to the IRB. Should changes to the study protocol become necessary, the protocol amendment 
will be approved by the IRB prior to implementation. Protocol administrative changes will be 
reviewed by the IRB. 
13.3 Informed Consent 
A properly executed, written Informed Consent, in compliance with 21 CFR Part 50 and 
HIPAA authorization, will be obtained from each participant prior to enrollment and the 
initiation of screening evaluations required by this protocol. A copy of the Informed 
Consent document will be reviewed and approved by Lilly for acceptability and submitted 
by or on behalf of the Investigator, together with the protocol, to the IRB for review and 
approval prior to the start of the study. The Informed Consent will be written in language 
fully comprehensible to the prospective participant. 
13.4 Participant Confidentiality 
All communications, reports, and participant samples will be identified only by a coded 
number and/or initials to maintain participant confidentiality. All records will be kept 
confidential to the extent permitted by law. If a waiver or authorization separate from the 
statement in the Informed Consent is required for permitting access to a participant’s medical 
records (e.g. HIPAA), the investigator will obtain such authorization prior to enrolling a 
participant in the study. The Principal Investigator will keep a separate log of participants,

Q. 
What if the needle did not retract after my injection?  
A. 
Do not touch the needle or replace the gray base cap. Put the Pen in a safe place to avoid an 
accidental needlestick and contact your study staff. 
 
Q. 
How can I tell if my injection is complete?  
A. 
After you press the purple injection button, you will hear 2 loud clicks. The second loud click tells you 
that your injection is complete. You will also see the gray plunger at the top of the clear base. The 
injection may take up to 15 seconds. 
 
Q. 
What if I remove the Prefilled Pen before the second loud click or before the gray plunger stops 
moving?  
A. 
You may not have given the full dose. Contact study staff. 
 
Q. 
What if I heard more than 2 clicks during my injection, 2 loud clicks and 1 soft one. Did I give a 
complete injection?  
A. 
Some people may hear a soft click right before the second loud click. That is the normal operation of 
the Prefilled Pen. Do not remove the Prefilled Pen from the injection pad until you hear the second 
loud click.
