1. Protocol Synopsis
Title of Study:
A Safety, Tolerability, and Pharmacokinetic Study of Injections of LY3074828 Solution Using Investigational 
1-mL Pre-filled Syringes and Investigational 1-mL Autoinjector in Healthy Subjects
Rationale: 
Study I6T-MC-AMBE (AMBE) will assess the pharmacokinetics (PK), safety and tolerability of, and pain 
associated with, a 125-mg subcutaneous (SC) dose of LY3074828 solution formulation administered using an 
investigational manual 1-mL pre-filled syringe (PFS) or an investigational 1-mL autoinjector (AI).  Both methods of 
administration will be evaluated at 3 different injection sites (arm, thigh, and abdomen) in order to expand the 
options for administration in patient use.  The study will provide data to bridge PFS administration of LY3074828, 
with the investigational AI device planned for use in subsequent studies and patient use.
Objectives/Endpoints:

Summary of Study Design:
Study I6T-MC-AMBE (AMBE) is a single-center, randomized, parallel-arm, open-label, Phase 1 single-dose study 
of LY3074828 solution formulation in healthy subjects.  Pharmacokinetics, safety and tolerability of, and pain 
associated with, 125-mg SC doses administered using a PFS or an investigational AI at 3 different injection sites 
will be evaluated.
Subjects will be randomized to a 1-mL PFS administration to the arm, thigh, or abdomen or a 1-mL AI
administration to the arm, thigh, or abdomen.  Subjects will report to the clinical research unit (CRU) on Day -1 and 
will remain at the CRU until the scheduled procedures have been completed on Day 2.  Study drug will be 
administered by investigative site staff by SC injection per the randomization scheme in the morning of Day 1 after 
an overnight fast.  Subjects will be followed for 12 weeks following dose administration.
Safety and tolerability will be assessed by clinical laboratory tests, vital sign measurements, 12-lead 
electrocardiograms, recording of adverse events and product complaints, physical examinations/medical 
assessments, immunogenicity, and injection-site assessments.  Pain assessments will be made using an injection-site 
pain visual analog scale (VAS).
Dosing Regimen Arms and Duration for an Individual Subject:  
Subjects will receive a 125-mg SC dose of LY3074828 and will be randomized to 1 of 6 dosing regimen arms:

Test 1:  1-mL AI injector containing 125 mg LY3074828 solution to be administered in the arm

Test 2:  1-mL AI injector containing 125 mg LY3074828 solution to be administered in the thigh

Test 3:  1-mL AI injector containing 125 mg LY3074828 solution to be administered in the abdomen

Reference 1:  1-mL PFS containing 125 mg LY3074828 solution to be administered in the arm

Reference 2:  1-mL PFS containing 125 mg LY3074828 solution to be administered in the thigh

Reference 3:  1-mL PFS containing 125 mg LY3074828 solution to be administered in the abdomen
Total duration of the study for each subject will be approximately 16 weeks (screening period ≤28 days, residential 
period of 2 days, and outpatient follow-up period of 12 weeks).
Number of Subjects:
A total of approximately 66 subjects who fulfill the eligibility criteria will be randomized to 1 of 6 dosing regimen 
arms, with 11 subjects randomized to each arm to ensure completion of 10 subjects in each (60 subjects completed 
in total).  A subject’s study participation is considered as complete if he/she receives the study drug as per the 
protocol requirements and completes all activities up to and including at least Day 57.  A maximum of 2 subjects per 
arm may be replaced if multiple subjects do not complete the study.
Statistical Analysis:
The area under the concentration versus time curve (AUC) from time zero to infinity (AUC[0-∞]), AUC from time 
zero to time t, where t is the last sample with a measurable concentration (AUC[0-tlast]), and maximum observed 
drug concentration (Cmax) will be log-transformed and analyzed using a linear fixed-effects model.  The model will 
include device and injection location as fixed effects.  The dosing regimen differences between AI and PFS 

I6T-MC-AMBE Clinical Pharmacology Protocol

LY3074828
administrations will be back-transformed to present the ratios of geometric least squares (LS) means and the 
corresponding 90% confidence interval (CI).
The time to Cmax (tmax) of LY3074828 between AI and PFS administrations will be analyzed using a Wilcoxon rank 
sum test.  Estimates of the median difference, 90% CIs, and p-values from the Wilcoxon rank sum test will be 
calculated.
Additional PK analyses may be conducted if deemed appropriate.
A linear fixed-effects model will be used to analyze the post-injection pain VAS scores.  The model will include 
device and injection location as fixed effects.  The LS means and differences in LS means will be presented along 
with the corresponding 90% CI. 
Safety parameters will be listed and summarized using standard descriptive statistics, as appropriate.

Study Rationale
Study I6T-MC-AMBE (AMBE) will assess the pharmacokinetics (PK), safety and tolerability of, 
and pain associated with, a 125-mg subcutaneous (SC) dose of LY3074828 solution formulation 
administered using an investigational manual 1-mL pre-filled syringe (PFS) or an investigational 
1-mL autoinjector (AI).  Both devices will be evaluated at 3 different injection sites (arm, thigh, 
and abdomen) in order to expand the options for administration in patient use.  The study will 
provide data to bridge PFS administration of LY3074828, with the investigational AI device 
planned for use in subsequent studies and patient use.
3.2.
Background
LY3074828 is a humanized immunoglobulin G4-variant monoclonal antibody that is directed 
against the p19 subunit of interleukin (IL)-23 and does not bind IL-12.  LY3074828 is being 
developed for the treatment of autoimmune diseases in which the IL-23 pathway is thought to 
have a significant pathogenic role.  Neutralization of IL-23 with an anti-mouse IL-23 surrogate 
antibody (directed against the p19 subunit) significantly reduced the development of arthritis and 
inhibited ileal inflammation in a mouse model of spondyloarthropathy with bowel inflammation 
(Ruutu et al. 2012).  Additionally, neutralization of IL-23 significantly reduced the disease score 
in the relapsing-remitting experimental autoimmune encephalomyelitis (multiple sclerosis-like) 
model in mice.  Anti-IL-23 antibody also demonstrated some efficacy in preclinical arthritis 
models, depending on the timing of intervention (Cornelissen et al. 2013).  
Psoriasis is one of the most common immune-mediated chronic inflammatory skin diseases, 
affecting about 2% to 3% of the world's population (Nestle et al. 2009; Perera et al. 2012).  A 
typical organ-specific T-cell-driven inflammatory disease, psoriasis, had been considered a 
T helper (Th) 1-type skin disease for decades until a new Th population, Th17, was identified 
(Lew et al. 2004; Steinman 2007; Weaver et al. 2007).  However, substantial clinical and basic 
research observations now suggest that the IL-23/Th17 axis is essential in the pathogenesis of 
psoriasis (Di Cesare et al. 2009).  Treatment of psoriasis with biologic therapy, particularly with 
those agents targeting the IL-23/Th17 axis, has demonstrated clinical activity in patients with 
psoriasis (Crow 2012).
As of the Investigator’s Brochure (IB) cutoff date (02 February 2018 for Phase 1 studies), there 
have been approximately 819 participants in studies of LY3074828.  These include 245 patients 
with psoriasis, 248 patients with ulcerative colitis, 85 patients with Crohn’s disease, and 
241 healthy subjects who were exposed to either placebo or LY3074828 at single doses ranging 
from 5 to 1200 mg and multiple doses up to a maximum of 1000 mg intravenous (IV) and 
300 mg SC.
Data from the clinical pharmacology development program are available for 2 completed 
Phase 1 studies (Studies I6T-MC-AMAA [AMAA] and I6T-MC-AMAE [AMAE]) and 

I6T-MC-AMBE Clinical Pharmacology Protocol

LY3074828
4 ongoing Phase 1 studies (Studies I6T-JE-AMAD [AMAD], I6T-MC-AMAL [AMAL],
I9O-MC-AABA [AABA], and I6T-MC-AMAQ [AMAQ]).
No deaths, serious adverse events (SAEs), or discontinuations due to an adverse event (AE) have 
been reported in any of the Phase 1 studies.
In the completed Study AMAA, a total of 82 treatment-emergent AEs (TEAEs) were reported by 
37 subjects.  The most commonly reported TEAEs in this study were nasopharyngitis and 
headache.  There were no drug-related TEAEs of National Cancer Institute Common 
Terminology Criteria for Adverse Events Grade 2 or higher reported in Study AMAA.  
In the completed Study AMAE, the incidence of TEAEs was similar between the 125 mg
LY3074828 lyophilized formulation and the 125 mg LY3074828 PFS solution formulation, with 
a notably higher number of TEAEs reported by healthy subjects who received 500 mg 
LY3074828 solution formulation.  The most common TEAEs related to study treatment were 
events occurring at the site of injection, including injection-site reaction (ISR) and injection-site 
hemorrhage.  Across all formulations, the majority of TEAEs reported during the study were 
mild, with only 1 TEAE that was moderate in severity but not related to study drug.  
There were no obvious trends in the pattern of AEs across studies apart from ISRs.  Injection-site 
pain, of short duration (usually hours), has been reported in both the completed and ongoing 
clinical pharmacology studies.  Preliminary data from Studies AMAE and AMAL showed that 
most ISRs were mild or moderate in severity, with severe injection-site pain reported in 2% of 
ISRs in the 125-mg SC solution test formulation group.
Immunogenicity evaluations were performed in Study AMAA. Blood samples to evaluate 
anti-drug antibody (ADA) were collected at baseline and approximately 22, 43, and 85 days 
postdose. Anti-drug antibody data were available for 45 subjects: 38 who received LY3074828 
and 7 who received placebo. All subjects who received placebo were ADA negative at baseline 
and post-baseline. Only 1 subject who received LY3074828 was positive at baseline. Thirty-one
subjects who received LY3074828 (81.6%) were negative at all post-baseline time points
evaluated. Seven subjects who received LY3074828 had a post-baseline positive titer; however,
only 3 of those subjects (7.9% of LY3074828-treated individuals) developed treatment-emergent 
ADA (TE-ADA). Treatment-emergent positive ADA was defined as ADA that developed 
following study drug administration with an increase to ≥1:20 titer (2 dilutions/4-fold increase) 
after a negative baseline result OR preexisting ADA (ADA positive at baseline) that was 
increased at least 2 dilutions/4-fold over baseline following study drug administration. None of 
these cases of TE-ADA were associated with treatment-emergent adverse events (TEAEs) or 
changes in the clearance of LY3074828 in this study.
Study AMAE evaluated the relative bioavailability of LY3074828 solution formulation in PFSs 
and a lyophilized formulation.  A total of 8 subjects (14.8%) were ADA positive at predose 
(pre-existing reactivity); none of the pre-existing reactivity confirmed as positive for neutralizing 
antibodies. The incidence of TEADAs was similar across formulations, with 7 subjects (38.9%) 
administered 250 mg LY3074828 lyophilized formulation, 6 subjects (33.3%) administered 
250 mg LY3074828 PFS solution formulation, and 7 subjects (38.9%) administered 500 mg 

I6T-MC-AMBE Clinical Pharmacology Protocol

LY3074828
LY3074828 PFS formulation testing positive for TEADAs. Most TEADAs were treatment-
induced (33.3% of subjects), with only 2 subjects having treatment-boosted TEADAs. Only 
1 subject had an ADA titer >1:1000 and there was no obvious trend towards a particular 
formulation having higher titers.
One subject had a TEADA titer greater than 1:1000 and met the protocol-defined requirement to 
have follow-up samples tested until titers were trending back to baseline. Multiple attempts were 
made to contact this subject for follow-up visits, but there was no response and the subject was 
considered lost to follow-up. The subject’s last recorded titer was 1:2560 at the final study visit
on Day 85.
3.3.
Benefit/Risk Assessment
Based on LY3074828 nonclinical and preliminary clinical data, there are no anticipated risks 
requiring monitoring beyond those for a typical humanized monoclonal antibody in human 
studies.  As with other immunomodulatory therapies, LY3074828 may increase the risk of 
developing an infection or may exacerbate an existing serious infection.  These may include 
opportunistic infections and reactivation of latent infections, such as tuberculosis (TB) and 
hepatitis B.  Subjects will therefore be screened for hepatitis B/C, human immunodeficiency 
virus (HIV), and TB.  Immunomodulatory therapies may increase the risk of malignancies; 
however, due to only single doses of LY3074828 being administered in this study, it is not 
considered necessary to monitor for such effects.  
Based on available data from Studies AMAA and AMAD, TE-ADAs have been observed in 2 of 
the 11 healthy subjects that received SC doses of LY3074828; however, titers were ≤1:160.  In 
the 33 patients with psoriasis who received single IV doses of LY3074828, TE-ADAs were 
detected in 3 subjects (Study AMAA).
No clinically significant safety or tolerability concerns have been identified in patients or healthy 
subjects to date for LY3074828 up to the highest doses given (single 2400-mg IV doses and 
2400-mg SC doses).  
Healthy subjects are not expected to derive any benefit from participating in studies with 
administration of LY3074828.  
As this study will use PFS and AIs, device-based risks will be evaluated.  Possible device-based 
risks include local effects such as pain at the injection sites from either the needle or the solution 
entry into the SC tissue, swelling, erythema, bleeding, and bruising.  These risks are mitigated by 
training of investigative site staff on proper injection techniques.  Systemic effects may include 
sweating, feeling faint, or fever, as a sign of infection.  
More information about the known and expected benefits, risks, SAEs, and reasonably 
anticipated AEs of LY3074828 are found in the compound IB, and risks as well as reasonably 
anticipated adverse device effects of the AI are found in the device IB.

5. Study Design
5.1.
Overall Design
Study I6T-MC-AMBE (AMBE) is a single-center, randomized, parallel-arm, open-label, Phase 1 
single-dose study of LY3074828 solution formulation in healthy subjects.  Pharmacokinetics, 
safety and tolerability of, and pain associated with, 125-mg SC doses administered using a PFS 
or AI at 3 different injection sites will be evaluated.
Screening Period (≤28 days):  Subjects will be evaluated for study eligibility ≤28 days prior to 
enrollment.
Residential Period (2 days):  A total of approximately 66 subjects who fulfill the eligibility 
criteria will be randomized to 1 of 6 dosing regimen arms, with 11 subjects randomized to each 
arm to ensure completion of 10 subjects in each:

Test 1:  1-mL AI injector containing 125 mg LY3074828 solution to be administered in 
the arm

Test 2:  1-mL AI injector containing 125 mg LY3074828 solution to be administered in 
the thigh

Test 3:  1-mL AI injector containing 125 mg LY3074828 solution to be administered in 
the abdomen

Reference 1:  1-mL PFS containing 125 mg LY3074828 solution to be administered in 
the arm

Reference 2:  1-mL PFS containing 125 mg LY3074828 solution to be administered in 
the thigh

Reference 3:  1-mL PFS containing 125 mg LY3074828 solution to be administered in 
the abdomen
Subjects will report to the clinical research unit (CRU) on Day -1 and will remain at the CRU 
until the scheduled procedures have been completed on Day 2.  Study drug will be administered 
by investigative site staff by SC injection per the randomization scheme in the morning of Day 1 
after an overnight fast.  
Safety and tolerability will be assessed by clinical laboratory tests, vital sign measurements, 
12-lead electrocardiograms (ECGs), recording of AEs and product complaints (PCs), physical 
examinations/medical assessments, immunogenicity, and injection-site assessments.  Pain 
assessments will be made using an injection-site pain visual analog scale (VAS).
Outpatient Follow-up Period (12 weeks):  The follow-up period will include outpatient visits 
for a total of 12 weeks (Days 4, 8, 11, 15, 22, 29, 43, 57, 71, and 85) following dose 
administration on Day 1 to assess the PK, safety and tolerability of, and pain associated with 
LY3074828 PFS and AI administrations.  Assessment of pain at the Follow-up visits does not 
include VAS score.

5.2.
Number of Participants
A total of approximately 66 subjects who fulfill the eligibility criteria will be randomized to 1 of 
6 dosing regimen arms, with 11 subjects randomized to each arm to ensure completion of
10 subjects in each.  A subject’s study participation is considered as complete if he/she receives 
the study drug as per the protocol requirements and completes all activities up to and including at 
least Day 57.  A maximum of 2 subjects per arm may be replaced if multiple subjects do not 
complete the study.
5.3.
End of Study Definition
End of the study is the date of the last visit or last scheduled procedure shown in the Schedule of 
Activities (Section 2) for the last subject.
5.4.
Scientific Rationale for Study Design
Conducting the study in healthy subjects mitigates the potential confounding effects of the 
disease state and concomitant medications in patients.  A population of healthy subjects is
frequently used in the assessment of bioavailability of both small and large molecules.
Single doses of LY3074828 and the PK sampling time points have been selected to generate PK 
profiles sufficient to fulfill the study objectives.  This study is not blinded due to the physical 
difference in devices being evaluated.  Subjects and site staff will be aware of the administration 
route and treatment.
A parallel-group design was chosen because a crossover design is impractical for compounds 
that have long half-lives, such as monoclonal antibodies.  Additionally, a crossover study design 
could confound PK data if subjects develop neutralizing ADAs.
Monoclonal antibody therapy has been associated with hypersensitivity reactions, including 
ISRs.  Follow-up details on ISRs will be collected by the investigative site regarding the severity, 
duration, type, and timing of the start of the event in relation to the start of study drug 
administration in order to further characterize these events.
Methods of administration will be evaluated at 3 different injection sites (arm, thigh, and 
abdomen) in order to expand the options for administration in patient use.  
5.5.
Justification for Dose
The doses for this study are based on the volume of solution that can be delivered by the PFS or 
AI (1 mL) and the solubility of LY3074828 (125 mg/mL), resulting in a dose of 125 mg
LY3074828.  
Intravenous doses up to 2400 mg and SC doses up to 2400 mg were found to be well tolerated in 
healthy subjects in the single-dose Studies AMAD and AABA.  Subcutaneous bioavailability 
was approximately 40% in Study AMAA.  In addition, 125 mg is one of the doses that are being 
evaluated in the Phase 3 development program.

6. Study Population
Eligibility of subjects for study enrollment will be based on the results of medical history, 
physical examination, vital signs, clinical laboratory tests, and ECG.  
The nature of any conditions present at the time of the physical examination and any preexisting 
conditions will be documented.
Screening will occur up to 28 days prior to enrollment.  Subjects who are not enrolled within 
28 days of screening may be subjected to an additional medical assessment and/or clinical 
measurements to confirm their eligibility.
Prospective approval of protocol deviations to recruitment and enrollment criteria, also known as 
protocol waivers or exemptions, are not permitted.
6.1.
Inclusion Criteria
Subjects are eligible for inclusion in the study only if they meet all of the following criteria at 
screening and/or enrollment:
[1]
are overtly healthy male or female subjects, as determined by medical 
history and physical examination
[1a]
male subjects:

no male contraception required except in compliance with specific local 
government study requirement
[1b]
female subjects:

All female subjects must test negative for pregnancy prior to initiation of treatment 
as indicated by a negative serum pregnancy test at the screening visit. Women of 
childbearing potential must also have a negative serum pregnancy test within 
24 hours prior to initial exposure.  Women not of childbearing potential due to 
postmenopausal status must have follicle-stimulating hormone >40 mIU/mL at the 
screening visit

Women of childbearing potential who are abstinent (if this is complete abstinence, 
as their preferred and usual lifestyle) or in a same-sex relationship (as part of their 
preferred and usual lifestyle) must agree to either remain abstinent or stay in a 
same-sex relationship without sexual relationships with males.  Periodic abstinence 
(eg, calendar, ovulation, symptothermal, post-ovulation methods), declaration of 
abstinence just for the duration of a trial, and withdrawal are not acceptable 
methods of contraception

Otherwise, women of childbearing potential participating must agree to use one 
highly effective method (less than 1% failure rate) of contraception, or a 
combination of 2 effective methods of contraception (for 12 weeks following 
dosing with the study drug)

I6T-MC-AMBE Clinical Pharmacology Protocol
Page 21
LY3074828
o
Either one highly effective method of contraception (such as combination 
oral contraceptives, implanted contraceptives, or intrauterine device) or a 
combination of 2 effective methods of contraception (such as male or 
female condoms with spermicide, diaphragms with spermicide, or cervical 
sponges) will be used.  The subject may choose to use a double-barrier
method of contraception.  Barrier protection methods without concomitant 
use of a spermicide are not reliable or acceptable methods.  Thus, each 
barrier method must include use of a spermicide.  It should be noted that the 
use of male and female condoms as a double-barrier method is not 
considered acceptable due to the high failure rate when these methods are 
combined

Women not of childbearing potential may participate and include those who are: 
o
infertile due to surgical sterilization (hysterectomy, bilateral oophorectomy, 
or tubal ligation) or congenital anomaly such as Müllerian agenesis; or 
o
postmenopausal – defined as either:

A woman at least 50 years of age with an intact uterus, not on 
hormone therapy, who has had either:

cessation of menses for at least 1 year; or 

at least 6 months of spontaneous amenorrhea with a 
follicle-stimulating hormone >40 mIU/mL; or 

A woman 55 years of age or older not on hormone therapy, who has 
had at least 6 months of spontaneous amenorrhea; or 

A woman at least 55 years of age with a diagnosis of menopause 
prior to starting hormone-replacement therapy
[2]
are between 18 and 65 years of age, inclusive, at time of screening
[3]
have a body mass index (BMI) of 18.0 to 32.0 kg/m2, inclusive, at time of 
screening

have venous access sufficient to allow for blood sampling as per the 
protocol
[6]
are reliable and willing to make themselves available for the duration of the 
study and are willing to follow study procedures
[7]
are able and willing to give signed informed consent

7. Dosing Regimens
7.1.
Dosing Regimens Administered
This study will evaluate the PK, safety and tolerability of, and pain associated with 125-mg SC 
doses administered using 1-mL PFS or an investigational 1-mL AI at 3 different injection sites.
Using the investigational 1-mL AI, the targeted injection duration will be approximately 5 to 
10 seconds.  Manual injection using the PFS should target an injection duration of about 5 to 
10 seconds to approximate the injection time range for the AI.  Approximate injection durations 
for AIs and PFSs will be obtained using a calibrated stopwatch and recorded in the electronic 
case report form (eCRF).  
Drug and device accountability records will be maintained by the site pharmacy.
Table AMBE.2 shows the dosing regimens for the study.

LY3074828
Prior to the PFS or AI injection, the investigator or his/her designee will prepare the subject’s 
skin per Instructions for Use (IFU).  Injections into the arm, thigh, or abdomen will be 
administered by investigative site staff according to the instructions provided by the sponsor.  All 
study injection sites will be marked using a template for size and with a surgical marker in order 
to identify study injection sites for later assessments.  Further information regarding SC 
administration will be included in the device IFU for the PFS and in the device IB (which 
contains IFU) for the AI.
In some cases, the site may destroy the material if, during the investigative site selection, the 
evaluator has verified and documented that the site has appropriate facilities and written 
procedures to dispose of clinical trial materials. 
7.1.1. Packaging and Labeling
LY3074828 will be supplied by the sponsor or its designee in accordance with current good 
manufacturing process, and labeled according to the country’s regulatory requirements.  All IPs
will be stored, inventoried, reconciled, and returned or destroyed according to applicable 
regulations. The following products will be supplied by Lilly:

pre-assembled LY3074828 PFSs, 1 mL

pre-assembled investigational LY3074828 AIs, 1 mL
Each investigational device will be individually identified and labeled according to US 
regulatory requirements for investigational devices.
7.2.
Method of Treatment Assignment

Preparation/Handling/Storage/Accountability
The IPs for this study will be:

LY3074828 in PFSs

LY3074828 in investigational AIs
Investigational product will be stored refrigerated at 2°C to 8°C (36°F to 46°F) in its original 
carton to protect from light.  Investigational product should not be frozen or shaken.  Sites will 
be required to monitor temperature of the on-site storage conditions of the IP.  The investigator 
or designee must confirm appropriate temperature conditions have been maintained, as 
communicated by sponsor, during transit for all IP received and any discrepancies are reported 
and resolved before use of the study treatment.
The AIs and PFSs containing LY3074828 should be allowed to warm to room temperature 
before use.  
Only participants enrolled in the study may receive IP or study materials, and only authorized 
site staff may supply or administer IP.  All IP should be stored in an environmentally controlled 
and monitored (manual or automated) area in accordance with the labeled storage conditions 
with access limited to the investigator and authorized site staff.
The investigator is responsible for study treatment accountability, reconciliation, and record 
maintenance (such as receipt, reconciliation, and final disposition records).
7.6.
Treatment Compliance
The IP will be administered at the clinical site, and documentation of treatment administration 
will occur at the site.
7.7.
Concomitant Therapy
Over-the-counter or prescription medications, including herbal medication, are not permitted 
within 14 days prior to dosing and throughout the study.  However, stable doses of oral 
contraceptive or hormone-replacement therapy are permitted at the discretion of the investigator.
Paracetamol/acetaminophen (up to 2 g/day) is permitted at the discretion of the investigator, but 
should be avoided during the 4-hour postdose period when pain assessments are made.  
Additional drugs are to be avoided during the study, unless required to treat an AE.
If the need for concomitant medication arises per Investigator discretion, continuation of the 
subject may be at the discretion of the investigator in consultation with a Lilly clinical 
pharmacologist (CP) or clinical research physician (CRP).  Any additional medication used 
during the course of the study must be documented.
7.8.

8. Discontinuation Criteria
8.1.
Discontinuation from Study Treatment
Randomized subjects who discontinue the study prematurely for any reason should complete the 
early discontinuation (ED) procedures as shown in the Schedule of Activities (Section 2).  The 
reason for and the date of discontinuation will be collected for all subjects.
8.1.1. Discontinuation of Inadvertently Enrolled Subjects
If the sponsor or investigator identifies a subject who did not meet enrollment criteria and was 
inadvertently enrolled, a discussion must occur between the Lilly CP or CRP and the investigator 
to determine if the subject may continue in the study.  If both agree it is medically appropriate to 
continue, the investigator must obtain documented approval from the Lilly CP or CRP to allow 
the inadvertently enrolled subject to continue in the study.  Any subjects that are inadvertently 
enrolled will be followed for safety.
8.2.
Discontinuation from the Study
Subjects will be discontinued in the following circumstances:

Enrollment in any other clinical study involving an IP or enrollment in any other type of 
medical research judged not to be scientifically or medically compatible with this study

Participation in the study needs to be stopped for medical, safety, regulatory, or other 
reasons consistent with applicable laws, regulations, and good clinical practice

The investigator decides that the subject should be discontinued from the study

The subject requests to be withdrawn from the study
Subjects who discontinue the study early will have ED procedures performed as shown in the 
Schedule of Activities (Section 2).
8.3.
Subjects Lost to Follow-up
A subject will be considered lost to follow-up if he or she repeatedly fails to return for scheduled 
visits and is unable to be contacted by the study site.  Site personnel are expected to make 
diligent attempts to contact subjects who fail to return for a scheduled visit or were otherwise 
unable to be followed up by the site.

I6T-MC-AMBE Clinical Pharmacology Protocol

9. Study Assessments and Procedures
Section 2 lists the Schedule of Activities, detailing the study procedures and their timing 
(including tolerance limits for timing).
Appendix 2 lists the clinical laboratory tests that will be performed for this study.
Appendix 5 provides a summary of the maximum number and volume of invasive samples, for
all sampling, during the study.
The specifications in this protocol for the timings of safety and sample collection are given as 
targets to be achieved within reasonable limits.  Modifications may be made to the time points 
based upon emerging clinical information.  The scheduled time points may be subject to minor 
alterations; however, the actual time must be correctly recorded in the eCRF.  Late collection 
outside the stipulated time allowances or failure to obtain samples due to clinical issues, such as 
problems with equipment, venous access, or subject defaulting on a scheduled procedure, will 
not be considered as protocol deviations but the site will still be required to notify the sponsor in 
writing via a file-note.
Unless otherwise stated in subsections below, all samples collected for specified laboratory tests 
will be destroyed within 60 days of receipt of confirmed test results.  Certain samples may be 
retained for a longer period, if necessary, to comply with applicable laws, regulations, or 
laboratory certification standards.
9.1.
Efficacy Assessments
This section is not applicable to this study.
9.2.
Adverse Events
Investigators are responsible for monitoring the safety of subjects who have entered this study 
and for alerting Lilly or its designee to any event that seems unusual, even if this event may be 
considered an unanticipated benefit to the subject.
The investigator is responsible for the appropriate medical care of subjects during the study.
Investigators must document their review of each laboratory safety report.
The investigator remains responsible for following, through an appropriate health care option, 
AEs that are serious or otherwise medically important, considered related to the IP or the study.  
The subject should be followed until the event resolves, stabilizes with appropriate diagnostic 
evaluation, or is reasonably explained.  The frequency of follow-up evaluations of the AE is left 
to the discretion of the investigator.
After the informed consent form is signed, study site personnel will record, via eCRF, the 
occurrence and nature of each subject’s preexisting conditions.  Additionally, site personnel will 
record any change in the condition(s) and the occurrence and nature of any AEs.  

I6T-MC-AMBE Clinical Pharmacology Protocol
Page 30
LY3074828
The investigator will interpret and document whether or not an AE has a reasonable possibility 
of being related to study treatment, study device, or a study procedure, taking into account 
concomitant treatment or pathologies.  
A “reasonable possibility” means that there is a cause and effect relationship between the IP, 
study device, and/or study procedure and the AE.
Planned surgeries should not be reported as AEs unless the underlying medical condition has 
worsened during the course of the study.
9.2.1. Serious Adverse Events
An SAE is any AE from this study that results in one of the following:

death

initial or prolonged inpatient hospitalization

a life-threatening experience (that is, immediate risk of dying)

persistent or significant disability/incapacity

congenital anomaly/birth defect

important medical events that may not be immediately life-threatening or result in death 
or hospitalization but may jeopardize the patient or may require intervention to prevent 
one of the other outcomes listed in the definition above

when a condition related to the investigational device (PFS or AI) necessitates medical or 
surgical intervention to preclude either permanent impairment of a body function or 
permanent damage to a body structure, the serious outcome of “required intervention” 
will be assigned.
Study site personnel must alert the Lilly CRP/CP, or its designee, of any SAE as soon as 
practically possible.
Additionally, study site personnel must alert Lilly Global Patient Safety (GPS), or its designee, 
of any SAE within 24 hours of investigator awareness of the event via a sponsor-approved 
method.  If alerts are issued via telephone, they are to be immediately followed with official 
notification on study-specific SAE forms.  This 24-hour notification requirement refers to the 
initial SAE information and all follow-up SAE information.
Although all AEs are recorded in the eCRF after signing informed consent, SAE reporting to the 
sponsor begins after the subject has signed informed consent and has received IP.  However, if 
an SAE occurs after signing informed consent, but prior to receiving IP, AND is considered 
Reasonably Possibly Related to a study procedure then it MUST be reported.
Investigators are not obligated to actively seek AEs or SAEs in subjects once they have 
discontinued from and/or completed the study (the subject summary eCRF has been completed).  
However, if the investigator learns of any SAE, including a death, at any time after a subject has 

I6T-MC-AMBE Clinical Pharmacology Protocol
Page 31
LY3074828
been discharged from the study, and he/she considers the event reasonably possibly related to the 
study treatment or study participation, the investigator must promptly notify Lilly. 
Pregnancy (maternal or paternal exposure to IP) does not meet the definition of an AE.  
However, to fulfill regulatory requirements any pregnancy should be reported following the SAE 
process to collect data on the outcome for both mother and fetus.
9.2.1.1.
Adverse Device Effects
Any AE believed to have a reasonable possibility of being related or associated to an issue with 
the AI or PFS, such as a malfunction or a deficiency, is considered an adverse device event.  
These events must be clearly indicated as such in the eCRF, and reported to the sponsor. A 
Product Complaint should also be reported.
For the purpose of this protocol, “unanticipated” serious adverse device effect means any SAE
alleged to have a reasonable possibility to be associated or related to the device, which was not 
previously defined as anticipated in study documents, such as the device IB or IFU.  The SAE 
relatedness must be clearly indicated as such in the eCRF, and reported to the sponsor within 
24 hours of site knowledge of the event.  A Product Complaint should also be reported.
9.2.1.2.
Adverse Events of Special Interest
The following AEs of special interest will be used to determine the safety and tolerability of 
LY3074828 injections administered by either PFS or investigational AI in this clinical study.
Adverse events of special interest for LY3074828 are:

infection

ISRs

allergic/hypersensitivity reactions
If infections, ISRs, or allergic/hypersensitivity reactions are reported, sites will provide details on 
these events as instructed on the eCRF.  Investigators will also educate subjects about the 
symptoms of allergic/hypersensitivity reactions and will provide instructions on dealing with 
these reactions.  A blood sample will be collected when possible for any subject who experiences 
an AE of allergic/hypersensitivity reaction during the study.
9.2.1.3.
Suspected Unexpected Serious Adverse Reactions 
Suspected unexpected serious adverse reactions (SUSARs) are serious events that are not listed 
in the IB and that the investigator reports as related to IP or procedure.  Lilly has procedures that 
will be followed for the recording and expedited reporting of SUSARs that are consistent with 
global regulations and the associated detailed guidances.
9.2.2. Complaint Handling
Lilly collects PCs on IPs and drug delivery systems used in clinical trials in order to ensure the 
safety of study participants, monitor quality, and to facilitate process and product improvements.

I6T-MC-AMBE Clinical Pharmacology Protocol
Page 32
LY3074828
Subjects should be instructed to contact the investigator as soon as possible if he or she has a 
complaint or problem with the IP or drug delivery system so that the situation can be assessed.  
A PFS or AI that is associated with a product quality issue or complaint must be returned to 
Lilly.
The investigator or his/her designee is responsible for reporting and handling the following 
aspects of the Product Complaints (PC) process in accordance with instructions on the Product 
Complaints form, and the instructions provided for this study:

recording a complete description of the PC reported and any associated AEs using the 
study-specific complaint forms provided for this purpose

forwarding via email or fax the completed Product Complaint form within 24 hours to 
Lilly or its designee if associated to an SAE, otherwise within 1 business day.
If the investigator is asked to return the product for investigation, he/she will return a copy of the
completed Product Complaint form with the product.
9.3.
Treatment of Overdose
For the purposes of this study, an overdose of LY3074828 is considered any dose higher than the 
dose assigned through randomization.
There is no specific antidote for LY3074828.  In the event of an overdose, the subject should 
receive appropriate supportive care and any AEs should be documented.
Refer to the study drug IB for further details.
9.4.
Safety
9.4.1. Laboratory Tests
For each subject, laboratory tests detailed in Appendix 2 should be conducted according to the 
Schedule of Activities (Section 2).
Lilly or its designee will provide the investigator with the results of laboratory tests analyzed by 
a central vendor, if a central vendor is used for the study.
9.4.2. Vital Signs
For each subject, vital sign measurements (blood pressure, pulse rate, and temperature) should be 
conducted according to the Schedule of Activities (Section 2).  Additional vital signs may be 
measured during the study if warranted.
Blood pressure and pulse rate should be measured after at least 5 minutes supine.
If orthostatic measurements are required, subjects should be supine for at least 5 minutes and 
stand for at least 2 minutes.

I6T-MC-AMBE Clinical Pharmacology Protocol
Page 33
LY3074828
If the subject feels unable to stand, supine vital signs only will be recorded. 
Unscheduled orthostatic vital signs should be assessed, if possible, during any AE of dizziness or 
posture-induced symptoms.  
9.4.3. Electrocardiograms
For each subject, a single 12-lead digital ECG will be collected according to the Schedule of 
Activities (Section 2).  Electrocardiograms must be recorded before collecting any blood 
samples.  Subjects must be supine for at least 5 minutes before ECG collection and remain 
supine but awake during ECG collection.  Electrocardiograms may be obtained at additional 
times, when deemed clinically necessary.  All ECGs recorded should be stored at the 
investigational site.
Electrocardiograms will be interpreted by the investigator or qualified designee at the site as 
soon after the time of ECG collection as possible, and ideally while the subject is still present, to 
determine whether the subject meets entry criteria at the relevant visit(s) and for immediate 
subject management, should any clinically relevant findings be identified.  
If a clinically significant finding is identified (including, but not limited to, changes in QT/QTc 
interval from baseline) after enrollment, the investigator will determine if the subject can 
continue in the study.  The investigator, or qualified designee, is responsible for determining if 
any change in subject management is needed, and must document his/her review of the ECG 
printed at the time of collection.  
Any clinically significant findings from ECGs that result in a diagnosis and that occur after the 
subject receives the first dose of the IP should be reported to Lilly, or its designee, as an AE via 
eCRF.
9.4.4. Other Tests
9.4.4.1.
Tuberculosis Testing
Subjects will be tested as indicated in the Schedule of Activities (Section 2) for evidence of 
active or latent TB using the QuantiFERON-TB Gold test.  If the test is indeterminate, 1 retest is 
allowed.  If the retest is indeterminate, the subject will be excluded from the study.
Subjects who have had household contact with a person with active TB must be excluded unless 
appropriate and documented prophylaxis treatment for TB has been completed.
Subjects with any history of active TB are excluded from the study, regardless of previous or 
current TB treatments.
9.4.4.2.
Injection Duration Assessments
Injection duration will be measured by a calibrated stopwatch by qualified trained study staff.  
The duration of injection for the PFS will be defined as the time between when the plunger rod is 
pressed down and when all of the LY3074828 solution is injected.  The duration of injection for 
the AI will be defined as the time between the first audible click after the injection button is 

I6T-MC-AMBE Clinical Pharmacology Protocol
Page 34
LY3074828
pressed and the last audible click, which indicates that the needle has retracted and the injection 
is complete.  
9.4.4.3.
Injection-Site Assessments
Injection site findings (including erythema, induration, pruritus, and edema) will be captured on 
a separate ISR form, as indicated in the Schedule of Activities (Section 2).
Data from injection site evaluations (including pain) which are recorded as a result of specific 
questionnaire/s will not be reported as AEs. If the investigator determines that the ISR is
clinically significant or if it is an unsolicited event (volunteered by subject), the event will be 
captured in the subject’s eCRF as an AE.  
If an ISR is deemed to be an AE, the ISR form will be used to capture specific information about 
this reaction (eg, degree and area of erythema).
Injection-site tenderness on contact reported by subjects may be recorded as an AE, but is not 
required to be captured in ISR form.
9.4.4.4.
Bleeding Assessment
All injection sites will be observed at the times indicated in the Schedule of Activities (Section 2) 
by the investigator or designee, and the presence of visible bleeding will be recorded on the 
eCRF.  A bandage may be placed on the injection site after assessment.
9.4.4.5.
Injection-Site Pain
Pain measurements will be quantified using the 100-mm validated VAS pain score for all 
subjects, whether or not they report injection pain.  The VAS is a well-validated tool 
(Williamson and Hoggart 2005) to assess injection-site pain; it is presented as a 100-mm line 
anchored by verbal descriptors, usually “no pain” and “worst possible pain.”  The subject will be 
asked to rate any pain at the injection site on a scale of 0 to 100 mm on the line immediately 
(within 1 minute) following the injection and at the time points listed in the Schedule of 
Activities (Section 2).
9.4.5. Safety Monitoring
The Lilly CP or CRP/scientist will monitor safety data throughout the course of the study.
Lilly will review SAEs within time frames mandated by company procedures.  The Lilly CP or 
CRP will periodically review the following data:

trends in safety data

laboratory analytes

AEs, including monitoring of incidence of any nature of any infections, and ISRs

PCs

I6T-MC-AMBE Clinical Pharmacology Protocol
Page 35
LY3074828
When appropriate, the Lilly CP or CRP will consult with the functionally independent GPS 
therapeutic area physician, GPS device physician, or GPS clinical research scientist.
9.4.5.1.
Hepatic Safety
If a study subject experiences elevated alanine aminotransferase (ALT) ≥3× upper limit of 
normal (ULN), alkaline phosphatase (ALP) ≥2× ULN, or elevated total bilirubin (TBL) 
≥2× ULN, liver tests (Appendix 4) should be repeated within 3 to 5 days including ALT, 
aspartate aminotransferase, ALP, TBL, direct bilirubin, gamma-glutamyl transferase, and 
creatine phosphokinase to confirm the abnormality and to determine if it is increasing or 
decreasing.  If the abnormality persists or worsens, clinical and laboratory monitoring should be 
initiated by the investigator based on consultation with the Lilly CP or CRP.  Monitoring should 
continue until levels normalize and/or are returning to approximate baseline levels. 
Additional safety data should be collected if 1 or more of the following conditions occur: 

elevation of serum ALT to ≥5× ULN on 2 or more consecutive blood tests

elevated serum TBL to ≥2× ULN (except for cases of known Gilbert’s syndrome)

elevation of serum ALP to ≥2× ULN on 2 or more consecutive blood tests 

hepatic event considered to be an SAE
9.4.5.2.
Monitoring of Hypersensitivity Reactions
There is a risk of systemic hypersensitivity reactions with any biological agent, including acute 
anaphylaxis and delayed hypersensitivities to LY3074828.  Symptoms and signs that may occur 
as part of these hypersensitivity reactions include, but are not limited to: fever, chills, joint and 
muscle pain, rash, itching, urticaria, dizziness, headache, throat irritation, and shortness of 
breath.  Less commonly, life-threatening anaphylactic reactions may occur, which may include 
vascular collapse and/or respiratory compromise.
All subjects will be closely monitored for signs and symptoms of hypersensitivity reactions 
following administration of the study drug, and appropriate medical care should be provided.  
Hypersensitivity reactions will be evaluated by examination of TEAEs and SAEs, and through 
the use of a follow-up form which will be completed by the investigator.  Potential 
hypersensitivity events will be evaluated by a Lilly CRP based on accepted criteria (Sampson et 
al. 2006).
In the event of drug hypersensitivity reactions (immediate or non-immediate), additional samples 
will be collected as close to the onset of the event as possible, at the resolution of the event, and
approximately 30 days following the event to evaluate ADA, PK, and additional exploratory 
biomarkers of hypersensitivity which could include tryptase, complement levels and cytokine 
measurements. Instructions for the collection and handling of blood samples will be provided by 
the sponsor. The actual date and time (24-hour clock time) of each sampling will be recorded.

I6T-MC-AMBE Clinical Pharmacology Protocol

9.5.
Pharmacokinetics
At the visits and times specified in the Schedule of Activities (Section 2), venous blood samples 
of approximately 2 mL each will be collected to determine the serum concentrations of 
LY3074828.  A maximum of 3 samples may be collected at additional time points during the 
study if warranted and agreed upon between both the investigator and sponsor.  Instructions for 
the collection and handling of blood samples will be provided by the sponsor.  The actual date 
and time (24-hour clock time) of each sampling will be recorded.
9.5.1. Bioanalysis
Samples will be analyzed at a laboratory approved by the sponsor and stored at a facility 
designated by the sponsor.  Concentrations of LY3074828 will be assayed using a validated 
enzyme-linked immunosorbent assay.  
Bioanalytical samples collected to measure IP concentrations will be retained for a maximum of 
1 year following last subject visit for the study.  During this time, samples remaining after the 
bioanalysis may be used for exploratory metabolism or exploratory analyses such as 
bioanalytical assay validation or cross-validation exercises.
9.6.
Pharmacodynamics
9.6.1. Immunogenicity Assessments
Blood samples for immunogenicity testing will be collected to determine antibody production 
against LY3074828, as specified in the Schedule of Activities (Section 2).  Additional samples 
may be collected if there is a possibility that an AE is immunologically mediated.  If additional 
immunogenicity testing samples are taken, matching PK sample collections will also be required.  
Immunogenicity will be assessed by a validated assay designed to detect ADAs in the presence 
of the IP.  Antibodies may be further characterized and/or evaluated for their ability to neutralize 
the activity of the IP.  
A risk-based approach will be used to monitor subjects who develop TE-ADAs during and 
following treatment with LY3074828.
Subjects will have ADA sampling at the visits specified in the Schedule of Activities (Section 2).
Subjects who have clinical sequelae that are considered potentially related to the presence of 
TE-ADA may be asked to return for additional follow-up testing.
Samples will be retained for a maximum of 15 years after the last subject visit, or for a shorter 
period if local regulations and institutional review boards (IRBs) allow, at a facility selected by 
the sponsor.  The duration allows the sponsor to respond to future regulatory requests related to 
the IP.  Any samples remaining after 15 years will be destroyed.

I6T-MC-AMBE Clinical Pharmacology Protocol

LY3074828
9.7.
Genetics
A blood sample will be collected for pharmacogenetic analysis as specified in the Schedule of 
Activities (Section 2), where local regulations allow.  
Samples will not be used to conduct unspecified disease or population genetic research either 
now or in the future.  Samples will be used to investigate variable exposure or response to 
LY3074828 and to investigate genetic variants thought to play a role in autoimmune and 
inflammatory diseases.  Assessment of variable response may include evaluation of AEs or 
differences in efficacy.  
All samples will be coded with the subject number.  These samples and any data generated can 
be linked back to the subject only by the investigative site personnel.  
Samples will be retained for a maximum of 15 years after the last subject visit, or for a shorter 
period if local regulations and/or IRB impose shorter time limits, for the study at a facility 
selected by Lilly or its designee.  This retention period enables use of new technologies, response 
to regulatory questions, and investigation of variable response that may not be observed until 
later in the development of LY3074828 or after LY3074828 is commercially available.  
Molecular technologies are expected to improve during the 15-year storage period and therefore 
cannot be specifically named.  However, existing approaches include whole genome or exome 
sequencing, genome wide association studies, multiplex assays, and candidate gene studies.  
Regardless of technology utilized, data generated will be used only for the specific research 
scope described in this section.

Statistical Considerations and Data Analysis
10.1. Sample Size Determination
Approximately 66 subjects will be enrolled with a target of 60 subjects completing the study 
(10 completers per treatment). 
Data from AMAL (2 x 1-mL doses of 125 mg LY3074828) and AMAE (2 x 1-mL PFS doses of 
125 mg LY3074828) studies showed that the geometric coefficient of variation ranged from 55% 
to 40% for the PK measurements (ie, area under the concentration versus time curve [AUC] from 
time zero to infinity [AUC(0-∞)], AUC from time zero to time t, where t is the last sample with a 
measurable concentration [AUC(0-tlast)], and maximum observed drug concentration [Cmax]).
Thus, the geometric coefficient of variation was assumed to be 55% when calculating precision.
A sample size of 60 subjects will provide a precision (ie, half-width of 90% of confidence 
interval [CI] with a coverage probability of 90%), in log scale, of approximately 0.48 for 
the geometric means ratio of reference versus test for AUC(0-∞), AUC(0-tlast), and Cmax. 
Equivalently, there is a 90% probability that the distance between the lower limit of the 90% CI 
and the point estimate of the geometric means ratio is not larger than 38%.
Subjects who are randomized but not administered treatment, or subjects (maximum of
2 subjects per dose regimen arm) that are administered treatment but do not have PK and ADA 
samples collected up to and including Day 57, may be replaced to ensure that approximately 
10 subjects from each treatment arm may complete the study.
10.2. Populations for Analyses
10.2.1. Study Participant Disposition
A detailed description of subject disposition will be provided at the end of the study. 
10.2.2. Study Participant Characteristics
The subject’s age, sex, weight, BMI, height, race/subrace, and other demographic data will be 
summarized by dosing regimen and overall.
10.3. Statistical Analyses
Statistical analysis of this study will be the responsibility of Eli Lilly and Company or its 
designee.
Pharmacokinetic analyses will be conducted on the full analysis set.  This set includes all data 
from all randomized subjects receiving the dose of LY3074828 with evaluable PK data.  Safety 
analyses will be conducted for all subjects receiving a dose of LY3074828, whether or not they 
completed all protocol requirements.

I6T-MC-AMBE Clinical Pharmacology Protocol
Page 39
LY3074828
Additional exploratory analyses of the data will be conducted as deemed appropriate.  Study 
results may be pooled with the results of other studies for population PK analysis purposes to 
avoid issues with post-hoc analyses and incomplete disclosures of analyses.  
No adjustments for multiple comparisons will be made.
10.3.1. Safety Analyses
10.3.1.1. Clinical Evaluation of Safety
All IP and protocol procedure AEs and PCs will be listed, and if the frequency of events allows, 
safety data will be summarized using descriptive methodology.
The incidence of symptoms for each treatment will be presented by severity and by association 
with IP as perceived by the investigator.  Symptoms reported to occur prior to study entry will be 
distinguished from those reported as new or increased in severity during the study.  Each 
symptom will be classified by the most suitable term from the medical regulatory dictionary.
The number of IP- and device-related SAEs and any related PCs will be reported.
10.3.1.2. Statistical Evaluation of Safety
10.3.1.2.1.Injection-Site Pain
The intensity of pain at the injection site within 1 minute of the end of injection and 5 minutes 
after the end of the injection will be evaluated, as reported by the subject and measured 
according to the 0- to 100-mm VAS.  VAS scores will be categorized into mild (0- to 30-mm), 
moderate (31- to 70-mm), and severe (71- to 100-mm).  Assessments will also be performed at 
15, 30, 60, and 120 minutes post-injection; however, the primary endpoints will be the 1- and 
5-minute assessments. 
Descriptive statistics will be used to summarize the intensity of pain at each time point.
A linear fixed-effects model will be used to analyze the 1- and 5-minute post-injection pain VAS 
scores separately.  The model will include device and injection location as fixed effects.  The 
least squares (LS) means and differences in LS means will be presented along with the 
corresponding 90% CI overall and by location as subgroups.  The distribution of the data will be 
explored prior to analysis to determine whether data transformation is required.  It is possible 
that the pain scores will be 0, so if the distribution of the data implies that a log-transformation is 
required then the score may be updated to log(VAS+1) to allow for the inclusion of the 0 values 
in the analysis.  If the assumptions of this model appear violated, a non-parametric method may 
be used.
10.3.1.2.2.Duration of Injection
The duration of the injection (measured in seconds) will be summarized for each drug delivery 
device for each injection site.

I6T-MC-AMBE Clinical Pharmacology Protocol
Page 40
LY3074828
10.3.1.2.3.Injection-Site Assessments
The incidence of the following AEs will be listed and summarized for each drug delivery device 
for each injection site: erythema, induration, pruritus, and edema.  Occurrence of bleeding will 
be listed.  
10.3.1.2.4.Statistical Evaluation of Other Safety Parameters
Other safety parameters that will be assessed include clinical laboratory parameters and vital 
signs.  The parameters and changes from baseline (predose), where appropriate, will be listed 
and summarized using standard descriptive statistics.  Additional analyses will be performed if
warranted upon review of the data.
10.3.2. Pharmacokinetic Analyses
10.3.2.1. Pharmacokinetic Parameter Estimation
Pharmacokinetic parameter estimates for LY3074828 will be calculated by standard 
noncompartmental methods of analysis.
The primary parameters for analysis will be AUC(0-∞), AUC(0-tlast), and Cmax for LY3074828.  
The secondary parameter for analysis will be the time to maximum observed drug concentration 
(tmax) of LY3074828.  Other noncompartmental parameters, such as half-life associated with the 
terminal rate constant (t1/2), apparent total body clearance of drug calculated after extra-vascular 
administration (CL/F), and apparent volume of distribution during the terminal phase after 
extra-vascular administration (Vz/F), may be reported.
10.3.2.2. Pharmacokinetic Statistical Inference
The AUC(0-∞), AUC(0-tlast), and Cmax will be log-transformed and analyzed using a linear 
fixed-effects model.  The model will include device and injection location as fixed effects.  The 
dosing regimen differences between AI and PFS administrations will be back-transformed to 
present the ratios of geometric LS means and the corresponding 90% CI.  Comparisons will be 
made between the 2 devices and then between the 3 injection locations.
The tmax of LY3074828 between AI and PFS administrations will be analyzed using a Wilcoxon 
rank sum test.  Estimates of the median difference, 90% CIs, and p-values from the Wilcoxon 
rank sum test will be calculated.
Additional PK analyses may be conducted if deemed appropriate.
10.3.3. Pharmacodynamic Analyses
This section is not applicable for this study.
10.3.4. Pharmacokinetic/Pharmacodynamic Analyses
This section is not applicable for this study.

10.3.5. Evaluation of Immunogenicity
The frequency of formation of antibodies to LY3074828 will be determined.  
Treatment-emergent ADAs are those that are induced or boosted by exposure to study drug, with 
a 4-fold or greater increase in titer compared to baseline if ADAs were detected at baseline, or a 
titer 2-fold greater than the minimum required dilution (1:10) if no ADAs were detected at 
baseline.
If a neutralization assay is performed, the frequency of neutralizing antibodies will be 
determined.  The relationship between the presence (or absence) of antibodies and clinical 
parameters (AEs) will be assessed.  Likewise, the relationship between the presence of 
antibodies and the PK parameters or concentrations of LY3074828 may be assessed if deemed 
appropriate.
10.3.6. Data Review During the Study
Data may be accessed and analyzed while the trial is ongoing, but no changes to the study design 
are planned.  An assessment committee will not be formed.
Available safety data will be reviewed at approximately Day 30 of the last cohort dosed in order 
to review emerging safety and tolerability data.
10.3.7. Interim Analyses
No formal interim analysis will be conducted. Data may be accessed as described in 
Section 10.3.6.
