SC doses (200 and 400 mg) in healthy 
Chinese subjects.

Including Cmax, AUC(0-tlast), AUC(0-∞), and 
tmax of LY3074828.
Abbreviations:  AUC(0-∞) = area under the concentration versus time curve from time zero to infinity; 
AUC(0-tlast) = area under the concentration versus time curve from time zero to time t, where t is the last 
sample with a measurable concentration; Cmax = maximum observed drug concentration; IV = intravenous; 
PK = pharmacokinetic; SC = subcutaneous; TEAE = treatment-emergent adverse event; tmax = time to 
maximum observed drug concentration; VAS = visual analog scale.
Summary of Study Design:
Study I6T-MC-AMBD (AMBD) is a subject- and investigator-blinded, randomized, parallel-group, 
placebo-controlled, Phase 1 single-dose study of LY3074828 in healthy Chinese subjects.  Native Chinese subjects 
born in China, with all 4 grandparents and both parents of Chinese origin will be enrolled.  The study will consist of 
5 planned dose cohorts:  3 intravenous (IV) dose cohorts (300 mg, 600 mg, and 1200 mg) and 2 subcutaneous (SC)
dose cohorts (200 mg and 400 mg).  Subjects will be randomized within each cohort to receive LY3074828 
(10 subjects) or placebo (2 subjects).
Subjects will report to the clinical research unit (CRU) on Day -1.  After randomization, study drug will be 
administered by investigative site staff by either IV administration using a forearm vein or SC injection in the 
abdomen using pre-filled syringes in the morning of Day 1 after an overnight fast.  Subjects will remain at the CRU 
until the scheduled procedures have been completed on Day 2, and will then be discharged.  Subjects will be 
followed for approximately 12 weeks following dose administration.

LY3074828
Safety and tolerability will be explored by clinical laboratory tests, vital sign measurements, 12-lead 
electrocardiograms, recording of adverse events, physical examinations/medical assessments, immunogenicity, and 
injection-site assessments.  Pain assessments will be made using a subject-assessed injection-site pain visual analog 
scale.
Dosing Regimen Arms and Duration:  
Subjects will be randomized within each cohort to receive study drug or placebo:

Cohort 1:  a single dose of LY3074828 300 mg or placebo IV infused over at least 30 minutes (n=12; 
10 LY3074828, 2 placebo)

Cohort 2:  a single dose of LY3074828 600 mg or placebo IV infused over at least 60 minutes (n=12; 
10 LY3074828, 2 placebo)

Cohort 3:  a single dose of LY3074828 1200 mg or placebo IV infused over at least 2 hours (n=12; 
10 LY3074828, 2 placebo)

Cohort 4:  a single dose of LY3074828 200 mg or placebo SC (n=12; 10 LY3074828, 2 placebo)

Cohort 5:  a single dose of LY3074828 400 mg or placebo SC (n=12; 10 LY3074828, 2 placebo)
Dosing of cohorts may be conducted in parallel or sequentially at the discretion of the investigator.  Total duration 
of the study for each subject will be up to approximately 16 weeks (screening period ≤28 days, residential period of 
3 days/2 nights, and outpatient follow-up period of approximately 12 weeks).
Number of Subjects:
Sixty subjects who fulfill the eligibility criteria may be enrolled into the study to try to ensure that approximately 
50 subjects complete (10 subjects per cohort are required in order to provide the necessary safety and PK data). 
Furthermore, every effort should be made to enroll subjects so that at least 4 subjects per cohort are female. Each 
subject will participate in 1 of the 5 cohorts.  Subjects who withdraw from the study will not be replaced.  For 
analytical purposes, 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.
Statistical Analysis:
Safety parameters will be listed and summarized using standard descriptive statistics, as applicable.
Additional safety and tolerability analyses will be performed if warranted upon review of the data.
The frequency of formation of antibodies to LY3074828 will be listed.  If a neutralization assay is performed, the 
frequency of neutralizing antibodies will be listed.
Pharmacokinetic parameter estimates for LY3074828 will be calculated by standard noncompartmental methods of 
analysis.  The primary parameters for PK analysis will be 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).  The secondary parameter for 
analysis will be the time to maximum observed drug concentration (tmax) of LY3074828.  Other noncompartmental 
parameters, such as bioavailability following SC administration, half-life, clearance, and volume of distribution 
(apparent clearance and apparent volume of distribution for SC administration), may be reported.

3. Introduction
3.1.
Study Rationale
Study I6T-MC-AMBD (AMBD) is a clinical evaluation of LY3074828 in Chinese subjects, and is being conducted 
to investigate the safety, tolerability, and pharmacokinetics (PK) of single-dose administration of LY3074828 in this 
population.  Data from completed preclinical and clinical studies support the administration to healthy Chinese 
subjects within the dose range planned for this study.  This study will support future Phase 3 clinical studies in 
Chinese patients.
3.2.
Background
LY3074828 is a humanized immunoglobulin G4-variant monoclonal antibody that is directed against the 
p19 subunit of interleukin-23 (IL-23) and does not bind interleukin-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, there were approximately 819 participants in studies of 
LY3074828.  These included 245 patients with psoriasis, 248 patients with ulcerative colitis, 85 patients with 
Crohn’s disease (CD), 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 
subcutaneous (SC).  
Data from the clinical pharmacology development program are available for 1 completed Phase 1 study and 4 
ongoing Phase 1 studies, as follows.  
Completed Phase 1 study:

Study I6T-MC-AMAA (AMAA):  LY3074828 has been evaluated in 5 healthy subjects (single 120-mg 
SC doses) and in a total of 33 subjects with plaque psoriasis (single ascending IV doses of 5, 20, 60, 120, 
200, 350, or 600 mg).  
Ongoing Phase 1 studies:

I6T-MC-AMBD(c) Clinical Pharmacology Protocol

single IV doses of 60, 200, 600, 1200, or 2400 mg LY3074828 (or placebo), or single SC doses of 200 mg 
LY3074828 (or placebo).

Study I6T-MC-AMAL (AMAL):  A total of 67 healthy subjects were administered single IV or SC doses 
of 250 mg LY3074828.  


mg or 500 mg LY3074828; the study is evaluating relative bioavailability of solution compared to 
lyophilized formulations.  

Study I9O-MC-AABA (AABA):  A total of 72 healthy subjects were administered single IV doses of 1200 
mg LY3074828, or single SC doses of 250, 1000, or 2400 mg LY3074828 (SC doses coadministered with 
LY9999QS).
No deaths, serious adverse events (SAEs), or discontinuations due to an adverse event (AE) were reported in any of 
the Phase 1 studies, as of the IB cutoff date.
In the completed Study AMAA, a total of 82 treatment-emergent adverse events (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.  
There were no obvious trends in the pattern of AEs across studies apart from injection-site reactions.  Injection-site 
pain, of short duration (usually hours), has been reported in both the completed and ongoing clinical pharmacology 
studies.  In Study AMAA, injection-site pain (related to study drug) was reported in 3 out of 5 healthy subjects 
receiving 120 mg LY3074828 via SC administration; however, no infusion reactions were reported.  Preliminary 
data from Studies AMAE and AMAL showed that most injection-site reactions were mild or moderate in severity, 
with severe injection-site pain reported in 2% of injection-site reactions in the 250-mg SC test formulation group.  
 
 
 
 
 
  
 
 
 
 
  
LY3074828 is currently being evaluated in 3 ongoing Phase 2 studies, as follows:
Study I6T-MC-AMAC (AMAC) is being conducted in approximately 250 subjects with ulcerative colitis.  Three IV 
doses of 50, 200, or 600 mg LY3074828 (or placebo) are administered every 4 weeks (Q4W) during the induction 
period.  Subjects with a clinical response are subsequently administered SC doses of 200 mg LY3074828 (or 
placebo) Q4W or 200 mg LY3074828 every 12 weeks during the 92-week maintenance period.  Subjects with no 
CCI

I6T-MC-AMBD(c) Clinical Pharmacology Protocol

LY3074828
clinical response in the induction period may be administered 3 further 1000 mg LY3074828 IV doses Q4W, 
followed by 200 mg LY3074828 SC Q4W for 80 weeks. During the open-label extension portion of this study in 
which IV infusions of 1000 mg of LY3074828 were administered, a patient experienced an acute anaphylactic 
reaction.  As a result of this SAE, LY3074828 was discontinued for this patient.

Study I6T-MC-AMAF (AMAF) is being conducted in approximately 200 subjects with plaque psoriasis.  
Two SC doses of 30, 100, or 300 mg LY3074828 (or placebo) are administered every 8 weeks (Q8W) 
during the induction period, followed by 30, 100, or 300 mg Q8W or as required during the 88-week 
maintenance period.

Study I6T-MC-AMAG (AMAG) is being conducted in subjects with CD (85 subjects randomized, 
approximately 180 subjects planned).  Three IV doses of 200, 600, or 1000 mg LY3074828 (or placebo) 
are administered Q4W.  LY3074828-treated subjects with an improvement in CD score either continue 
with this dose regimen (with SC placebo to maintain blind), or are administered 300 mg LY3074828 SC 
(with IV placebo) Q4W, through Week 48.  Subjects who receive placebo or who did not have a clinical 
improvement in CD score receive 1000 mg LY3074828 IV (with SC placebo) Q4W through Week 48.  
Subjects with clinical benefit may continue with 300 mg LY3074828 SC Q4W for an additional 52 weeks
(open-label).  Two events of anaphylaxis were reported in this study, with 1 occurring during an infusion of 
LY3074828. The other event also occurred during an intravenous infusion, but the study team remained
blinded to study treatment.  In both cases, the infusions of study medication were stopped and patients were 
treated with antihistamines, which resulted in resolution of the patients’ symptoms.  Both patients were 
discontinued from the study.
To date, evaluation of the unblinded safety data from Studies AMAF and AMAC have not revealed any dose-related 
safety or tolerability issues.  
Pharmacokinetic results obtained from Study AMAA indicated that serum exposure of LY3074828 increases in a 
dose-proportional manner, and that the mean half-life associated with the terminal rate constant (t1/2) was 10.5 days, 
which did not appear to be dependent on dose.  Maximum concentrations were observed 3 days postdose following 
SC administration and, based on the area under the concentration versus time curve (AUC), the SC bioavailability 
was 40%.
A lyophilized SC formulation was used in Studies AMAA and AMAD and is currently being used in the Phase 2 
Studies AMAC, AMAF, and AMAG.  Data from Study AMAL indicate that the PK of LY3074828 following SC 
administration is similar in subjects receiving the lyophilized formulation versus the solution formulation that will 
be used in Phase 3 studies.  Preliminary data from Study AMAE also indicate that SC administration of the solution 
formulation using a pre-filled syringe (PFS) provides comparable LY3074828 exposure as the lyophilized SC 
formulation used in Phase 1 and 2 studies.
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 

I6T-MC-AMBD(c) Clinical Pharmacology Protocol
Page 18
LY3074828
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.  
 
 
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 1200-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, 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 to be found in the IB.

5. Study Design
5.1.
Overall Design
Study I6T-MC-AMBD (AMBD) is a subject- and investigator-blinded, randomized, placebo-controlled, parallel-
group, Phase 1 single-dose study of LY3074828 in healthy Chinese subjects.  Safety, tolerability, and PK of 
LY3074828 will be evaluated.
Native Chinese subjects born in China will be enrolled; all 4 biological grandparents and both biological parents 
must be of Chinese origin.  Every effort should be made to enroll subjects so that at least 4 subjects in each cohort 
will be female.  However, if the desired number of female subjects is not achieved, this will not constitute a protocol 
deviation.
Screening Period (≤28 days):  Subjects will be evaluated for study eligibility ≤28 days prior to enrollment.
Residential Period (3 days/2 nights):  A total of approximately 60 subjects (12 subjects per cohort) who fulfill the 
eligibility criteria will be enrolled into the study.  Subjects will be randomized within each cohort to receive study 
drug or placebo:

Cohort 1:  a single dose of LY3074828 300 mg or placebo IV infused over at least 30 minutes (10 
LY3074828, 2 placebo)

Cohort 2:  a single dose of LY3074828 600 mg or placebo IV infused over at least 60 minutes (10 
LY3074828, 2 placebo)

Cohort 3:  a single dose of LY3074828 1200 mg or placebo IV infused over at least 2 hours (10 
LY3074828, 2 placebo)

Cohort 4:  a single dose of LY3074828 200 mg or placebo SC (10 LY3074828, 2 placebo)

Cohort 5:  a single dose of LY3074828 400 mg or placebo SC (10 LY3074828, 2 placebo)
Dosing of cohorts may be conducted in parallel or sequentially at the discretion of the investigator.  Subjects will 
report to the clinical research unit (CRU) on Day -1.  After randomization, study drug will be administered by 
investigative site staff by IV administration using a forearm vein or SC injection in the abdomen using PFSs in the 
morning of Day 1 after an overnight fast.  Subjects will remain at the CRU until the scheduled procedures have been 
completed on Day 2, and will then be discharged.
Outpatient Follow-up Period (12 weeks):  The follow-up period will include outpatient visits for a total of 
approximately 12 weeks (Days 4, 8, 11 [SC only], 15, 22, 29, 43, 57, 71, and 85) following dose administration on 
Day 1 to assess the safety, tolerability, and PK of LY3074828 in healthy Chinese subjects.
Safety and tolerability will be explored by clinical laboratory tests, vital sign measurements, 12-lead 
electrocardiograms (ECGs), recording of AEs, physical examinations/medical assessments, immunogenicity, and 
injection-site assessments.  Pain assessments will be made using a subject-assessed injection-site pain visual analog 
scale (VAS).

5.2.
Number of Participants
Sixty subjects may be enrolled into the study to try to ensure that approximately 50 subjects complete (10 subjects 
per cohort are required in order to provide the necessary safety and PK data).  Furthermore, every effort should be 
made to enroll subjects so that at least 4 subjects per cohort are female.  Each subject will participate in 1 of the 5
cohorts.  Subjects who withdraw from the study will not be replaced. For analytical purposes, 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.
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
A subject- and investigator-blinded, randomized, and placebo-controlled design is being used to minimize bias on 
safety and tolerability assessments.
The parallel group design has been chosen due to the long half-life of LY3074828 and to determine the incidence of 
ADA formation.
It is not considered necessary to conduct safety data reviews of previous cohorts (lower dose levels) prior to dosing.  
This is because sufficient safety cover has already been obtained from previous studies to dose the highest IV and 
SC doses planned in this study (see Section 5.5).  Although sequential dosing of cohorts is not considered necessary 
from a safety perspective, it is anticipated that it may be preferred for logistical reasons.  The relative dosing of 
cohorts (parallel or sequential) will therefore be at the discretion of the investigator.  
A single dose on Day 1 will be given in order to evaluate the safety, tolerability, and PK profile of LY3074828 in 
healthy Chinese subjects.
Monoclonal antibody therapy has been associated with hypersensitivity reactions, including injection-site reactions.  
Follow-up details on injection-site reactions 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.

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 
requirements

Men should refrain from sperm donation for the duration of the study and for 12 weeks 
following dosing with the study drug
[1b] female subjects:

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 (e.g., 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)
o
Women of childbearing potential participating must test negative for pregnancy 
prior to initiation of treatment as indicated by a negative serum pregnancy test at 
the screening visit followed by a negative serum pregnancy test within 24 hours 
prior to exposure of study drug

I6T-MC-AMBD(c) Clinical Pharmacology Protocol
Page 23
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 a reliable or 
acceptable method.  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 mullerian 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 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

LY3074828 will be administered using a forearm vein as a slow IV infusion at an infusion rate of no greater than 10 
mg per minute. The duration of the placebo infusions will match those of the LY3074828 infusions to maintain 
subject and investigator blinding to study treatment.  Subcutaneous administration of the 200-mg dose of 
LY3074828 or placebo will be given by investigative site staff as 2 x 1-mL injections, with 1 injection into the 
skinfold of the left lower abdominal wall and the other into the skinfold of the right lower abdominal wall.  The SC 
administration of the 400-mg dose of LY3074828 will be given by investigative site staff as 4 x 1-mL injections, 
with the first 2 injections given into separate lower abdominal quadrants, and the final 2 injections given into 
separate upper abdominal quadrants.
The actual date and time of all dose preparation and administration will be documented, and drug accountability 
records will be maintained by the site pharmacy.
The investigator or designee is responsible for returning all unused medication to Lilly or its designee at the end of 
the study.
The site may destroy used syringes 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 materials.  

I6T-MC-AMBD(c) Clinical Pharmacology Protocol

LY3074828
7.1.1. Packaging and Labeling
LY3074828 and placebo will be supplied to the investigator by Lilly or its designee.  Clinical trial materials will be 
labeled according to the country’s regulatory requirements.  All IPs will be stored, inventoried, reconciled, and 
destroyed according to applicable regulations.  Clinical trial materials are manufactured in accordance with current 
good manufacturing practices.
Study drug will be supplied as a single-use solution vial or a single-use PFS containing LY3074828 or placebo with 
study-specific labels.  The 15-mL vial of LY3074828 is manufactured to deliver 300 mg (20 mg/mL).  The 1-mL 
PFS is manufactured to deliver 100 mg (100 mg/mL).  LY3074828 cannot be distinguished visually from placebo.  
Vials and PFSs will be supplied in cartons, with the appropriate quantity specific to the planned dispensing schedule 
of the IP.  
7.2.
Method of Treatment Assignment
Subjects will be randomized to LY3074828 or placebo within each cohort.
Randomization will be performed using a randomization table.
7.2.1. Selection and Timing of Doses
The actual time of all dose administrations will be recorded in the subject’s electronic case report form (eCRF).
7.3.
Blinding
This is a subject- and investigator-blinded study. The Sponsor and site pharmacists will be unblinded.  Blinding will 
be maintained throughout the conduct of the study.
Emergency codes will be available to the investigator.  A code, which reveals the treatment for a specific study 
subject, may be opened during the study only if the subject’s well-being requires knowledge of the subject’s 
treatment assignment.
In case of an emergency, the investigator has the sole responsibility for determining if unblinding of a subject’s
treatment assignment is warranted for medical management of the event.  The subject’s safety must always be the 
first consideration in making such a determination.  If the investigator decides that unblinding is warranted, it is the 
responsibility of the investigator to promptly document the decision and rationale and notify Lilly as soon as 
possible.
Upon completion of the study, all codes must be returned to Lilly or its designee.
7.4.
Dose Modification
Dose adjustments are not permitted in this study.
7.5.
Preparation/Handling/Storage/Accountability
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.

I6T-MC-AMBD(c) Clinical Pharmacology Protocol
Page 29
LY3074828
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, institution, or the head of the medical institution (where applicable) 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, until the subject’s last visit.  However, stable doses of oral contraceptive or 
hormone-replacement therapy (estrogen and thyroid) are permitted at the discretion of the investigator.
Paracetamol/acetaminophen (up to 2 g/day) is permitted at the discretion of the investigator.  Additional drugs are to 
be avoided during the study, unless required to treat an AE.
If the need for concomitant medication arises, inclusion or continuation of the subject may be at the discretion of the 
investigator after 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.

8. Discontinuation Criteria
8.1.
Discontinuation from Study Treatment
Randomized subjects who discontinue the study prematurely for any reason should complete the early 
discontinuation 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, 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.  
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

Investigator Decision
o
the investigator decides that the subject should be discontinued from the study

Subject Decision
o
the subject, or legal representative, requests to be withdrawn from the study.
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.

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.
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 for 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, or that caused the subject to discontinue 
the IP before completing 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.  
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, concomitant treatment, or pathologies.  
A “reasonable possibility” means that there is a potential 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

I6T-MC-AMBD(c) Clinical Pharmacology Protocol
Page 32
LY3074828

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 subject or may require intervention to prevent one of the other outcomes listed in 
the definition above

when a condition related to the investigational device (for example, drug delivery system) 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, 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 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 be related to an issue with the use of the study device (PFS) 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 (PC) should also be reported.
For the purpose of this protocol, “unanticipated” adverse device effect means any SAE alleged to be associated with 
or related to the device, and which has been confirmed as such by the Sponsor.  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 PC 
should also be reported.

I6T-MC-AMBD(c) Clinical Pharmacology Protocol
Page 33
LY3074828
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 PFS in this clinical study.
Adverse events of special interest for LY3074828 are:

infection

injection-site reactions

allergic/hypersensitivity reactions.
If infections, injection-site reactions, 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.
Although an increased risk of malignancy may be associated with immunomodulatory therapies, such effects will 
not be monitored in this study as subjects will only receive a single dose of LY3074828 or placebo.
Depression and suicidality may be increased with certain autoimmune disorders.  For this program of work, and 
where consistent with the study protocols, patients should be monitored for signs and symptoms of such behavior.  
Specific monitoring (e.g. Columbia Suicide Severity Rating Scale, Hamilton Depression Rating Scale) is not 
considered necessary for this study as the study population is healthy subjects (i.e. do not have autoimmune 
disorders such as ulcerative colitis or CD) and only single doses will be administered.  
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.
9.2.1.4.
Adverse Event Monitoring with a Systematic Questionnaire
Before the self-assessed pain VAS is conducted (see Section 9.4.4.2.3), study site personnel will question the subject 
about any change in the preexisting condition(s) (first assessment time point only) and the occurrence and nature of 
any AEs.  
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.
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 that is associated with a product 
quality issue or complaint must be returned to Lilly.
The investigator or his/her designee is responsible for handling the following aspects of the PC process in 
accordance with the instructions provided for this study:

I6T-MC-AMBD(c) Clinical Pharmacology Protocol
Page 34
LY3074828

recording a complete description of the PC reported and any associated AEs using the study-specific 
complaint forms provided for this purpose,

faxing the completed Product Complaint Form within 24 hours to Lilly or its designee.
If the investigator is asked to return the product for investigation, he/she will return a copy of the 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, clinical laboratory tests detailed in Appendix 2 should be conducted according to the Schedule of 
Activities (Section 2).
With the exception of safety laboratory test results that may unblind the study, Lilly or its designee will provide the 
investigator with the results of laboratory tests analyzed by a local laboratory used for the study.
9.4.2. Vital Signs
For each subject, vital sign measurements 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.
Unscheduled orthostatic vital signs should be assessed where considered appropriate by the investigator.  If 
orthostatic measurements are required, subjects should be supine for at least 5 minutes and stand for at least 3 
minutes.  If the subject feels unable to stand, supine vital signs only will be recorded.  
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 for safety or PK tests.  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 by the investigator.  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.  

I6T-MC-AMBD(c) Clinical Pharmacology Protocol
Page 35
LY3074828
If a clinically significant finding is identified (including, but not limited to, changes in QT/corrected QT 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 
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 
which includes a QuantiFERON-TB Gold test or TB T-Spot 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.
Subcutaneous Injection-site Assessments
9.4.4.2.1.
Subcutaneous Injection-Site Reactions
Injection-site reactions will be evaluated through the collection of pain assessments and specific site assessments for 
local tolerability which will evaluate erythema, induration, categorical pain, pruritus, edema, and bruising as
indicated in the Schedule of Activities (Section 2).  Data from injection site evaluations (including pain VAS 
[9.4.4.2.3]) which are recorded as a result of specific questionnaires will not be reported as AEs.  Any spontaneous 
reports by the subject will be reported as AEs.  Additionally, if during the assessment of the injection sites, a 
clinically significant reaction (including pain) is observed by site staff, an AE will be reported at the discretion of 
the Investigator.  For injection site reactions reported as an AE, additional characterization of the event will be 
documented using the injection site eCRF form.  
9.4.4.2.2.
Subcutaneous 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.  Injection site bleeding may be recorded as AE at the discretion of the investigator.
9.4.4.2.3.
Subcutaneous Injection-site Pain Visual Analog Scale
Pain measurements will be quantified using the 100-mm validated VAS 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 on a scale of 0 to 100 mm on the line immediately (approximately within 5 minutes) 
following the start of the first 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.

I6T-MC-AMBD(c) Clinical Pharmacology Protocol
Page 36
LY3074828
Lilly will review SAEs within time frames mandated by company procedures.  The Lilly CP or CRP will review the 
following data:

trends in safety data

laboratory analytes

AEs, including monitoring of incidence of any nature of any infections, injection-site reactions, and 
allergic/hypersensitivity reactions

PCs.
When appropriate, the Lilly CP or CRP will consult with the functionally independent Global Patient Safety (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 creatinine kinase 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 immunogenic response with any biological agent, including hypersensitivity reactions
(including non-immediate hypersensitivities), anaphylactic reactions, and infusion-related reactions.  Symptoms and 
signs that may occur as part of such a response include, but are not limited to, fever, chills, weakness of limbs, rash, 
itching, urticaria, dizziness, headache, tightening of throat, and wheezing.  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.  Any potential hypersensitivity events will be evaluated, during the trial level safety review and/or the 
preparation of the study report, by a Lilly CRP based on accepted criteria (Sampson et al. 2006).  
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 

I6T-MC-AMBD(c) Clinical Pharmacology Protocol
Page 37
LY3074828
be collected at additional time points during the study if warranted and agreed upon between 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.
Drug concentration information that may unblind the study will not be reported to investigative site or blinded 
personnel until the study has been unblinded.
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.  Analyses of 
samples collected from placebo-treated subjects are not planned.
Bioanalytical samples collected to measure IP concentrations will be retained for a maximum of 1 year following 
last subject visit for the study.

Statistical Considerations and Data Analysis
10.1. Sample Size Determination
Sixty subjects who fulfill the eligibility criteria may be enrolled into the study to try to ensure that approximately 50 
subjects (10 subjects per cohort) complete.  The number of subjects in Study AMBD is not sufficient for any formal 
ethnic comparison, but the safety, tolerability, and PK data will be assessed in Chinese subjects and will be used to 
support the inclusion of Chinese subjects in future studies involving LY3074828.  
The sample size is customary for Phase 1 studies evaluating safety and PK, and is not powered on the basis of 
statistical hypothesis testing.
Subjects who withdraw from the study will not be replaced.  For analytical purposes, 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.
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, 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 data from all subjects who receive IP and have evaluable PK. Safety 
analyses will be conducted for all enrolled subjects, whether or not they completed all protocol requirements.
Analysis will be according to the treatment the subjects actually received.  
Additional exploratory analyses of the data will be conducted as deemed appropriate.  
 
 
  
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 
CCI

I6T-MC-AMBD(c) Clinical Pharmacology Protocol
Page 40
LY3074828
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 sites immediately (approximately within 1 minute after start of first injection, 
designated as “0-hour assessment”) following the start of the first injection will be evaluated, as reported by the 
subject and measured according to the 0 to 100 mm VAS. Assessments will also be performed at 0.25, 0.5, 1, 2, and 
4 hours post first injection; however, the 0-hour assessment will be considered the primary endpoint for 
injection-site pain assessment.
Descriptive statistics will be used to summarize the intensity of pain at each time point as captured by the VAS.
10.3.1.2.2.Injection-site Assessments
Incidence of erythema, induration, categorical pain, pruritus, edema, bleeding, and bruising will be listed.
10.3.1.2.3.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 analysis 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 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) for LY3074828.  The secondary parameter for analysis will be the time to maximum observed 
drug concentration (tmax) of LY3074828.  Other PK parameters, such as bioavailability following SC 
administration, t1/2, clearance, and volume of distribution (apparent clearance and apparent volume of distribution 
for SC administration), may be reported.
10.3.2.2. Pharmacokinetic Statistical Inference
No formal statistical analysis will be performed for this study.  The PK parameters will be summarized by treatment 
and listed.  Additional analyses may be conducted as 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.

10.3.6. 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.  
10.3.7. Interim Analyses
No interim analyses are planned for this study.  If an unplanned interim analysis is deemed necessary, the Lilly CP, 
CRP/investigator, or designee will consult with the appropriate medical director or designee to determine if it is 
necessary to amend the protocol.

Summary
A Single-Dose Study to Assess the Safety, Tolerability, and 
Pharmacokinetics of LY3074828 in Healthy Chinese 
Subjects 
Overview
Protocol I6T-MC-AMBD, “A Single-Dose Study to Assess the Safety, Tolerability, and Pharmacokinetics of 
LY3074828 in Healthy Chinese Subjects”, has been amended.  The new protocol is indicated by Amendment (c) and 
will be used to conduct the study in place of any preceding version of the protocol.
The overall changes and rationale for the changes made to this protocol are as follows:

The statement that this is a single-site study has been removed throughout in order to allow flexibility in the 
number of sites at which the study may be conducted.    

A description of how the final report coordinating investigator will be identified if the study is conducted at 
more than 1 site has been added.
