1. Protocol Synopsis
Title of Study:
An Absolute Bioavailability Study of LY3314814 in Healthy Subjects Using an Intravenous Tracer Method
Rationale:  
Absolute bioavailability data are required by regulatory agencies in some geographical areas.  Knowledge of 
absolute bioavailability is helpful in the interpretation of pharmacokinetic (PK) data, and may be helpful in the 
design of clinical pharmacology studies.
Objectives/Endpoints:  
Objectives
Endpoints
Primary
The primary objective is to estimate the absolute 
bioavailability of LY3314814 following simultaneous 
administration of a single oral dose of 50 mg 
LY3314814 and a 2-hour intravenous (IV) infusion of 
approximately 100 g [13C4
15N3]-LY3314814(+)-
Camsylate (referred to as [13C4
15N3]-LY3314814 from 
this point forward) in healthy subjects.
The primary endpoint is LY3314814 absolute 
bioavailability, as calculated based on the ratio of the 
dose-adjusted area under the drug concentration-time 
curve (AUC) from zero to infinity (AUC[0-∞]) of 
LY3314814 and [13C4
15N3]-LY3314814.
Secondary
The secondary objectives are:
To assess the safety of LY3314814 following 
simultaneous administration of a single oral dose of 
50 mg LY3314814 and a 2-hour IV infusion of 
approximately 100 g [13C4
15N3]-LY3314814 in 
healthy subjects;
To characterize the PK parameters of LY3314814
and [13C4
15N3]-LY3314814 following simultaneous 
administration of a single oral dose of 50 mg 
LY3314814 and a 2-hour IV infusion of 
approximately 100 g [13C4
15N3]-LY3314814 in 
healthy subjects.
Secondary endpoints include:
Incidence of treatment-emergent adverse events
(AEs) and serious AEs;
LY3314814 and [13C4
15N3]-LY3314814 PK 
parameters:  AUC(0-∞), AUC from time zero to 
time tlast (AUC[0-tlast]), where tlast is the last time
point with a measurable concentration, maximum 
observed drug concentration (Cmax), time of 
maximum observed drug concentration (tmax), and 
half-life associated with the terminal elimination 
phase (t1/2).
Summary of Study Design:  
Study I8D-MC-AZEP is a Phase 1, single-center, open-label, single-period study to determine the absolute 
bioavailability of LY3314814 in healthy male and female subjects not of childbearing potential.
Treatment Arms and Duration:  
On Day 1, following an overnight fast of at least 8 hours, subjects will receive a single oral dose of 50 mg 
LY3314814 and at approximately the same time an IV infusion of approximately 100 g [13C4
15N3]-LY3314814 will 
be started.  The infusion will run for 2 hours.  

I8D-MC-AZEP(d) Clinical Pharmacology Protocol
Page 8
LY3314814
Number of Subjects:  
Up to 8 subjects may be enrolled and dosed to ensure that at least 6 subjects complete and have evaluable PK data.  
Statistical Analysis:  
Pharmacokinetic:  To quantify the absolute bioavailability of LY3314814, a mixed-effect analysis of variance model 
will be applied to the log-transformed dose-adjusted AUC of LY3314814 obtained after oral dosing and that of the 
IV administered [13C4
15N3]-LY3314814.  The model will contain formulation (oral or IV) as a fixed effect and 
subject as a random effect.  The absolute bioavailability will be expressed as the ratio of the least-squares geometric 
means of the formulations (oral : IV) along with its corresponding 90% confidence interval.  The PK parameter 
estimates for LY3314814, and [13C4
15N3]-LY3314814 will be summarized using appropriate descriptive statistics.  
Additional analysis may be conducted if deemed appropriate.
Safety:  All investigational product and protocol procedure AEs 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 investigational product as perceived by the investigator.  Each 
symptom will be classified by the most suitable term from the medical regulatory dictionary.  The number of 
investigational product-related serious AEs will be reported.  Safety parameters that will be assessed include clinical 
lab parameters, vital signs, and electrocardiograms. The clinical lab parameters will be listed.  Vital signs will be 
listed and summarized using standard descriptive statistics.  Electrocardiograms and physical examinations will be 
performed for safety monitoring purposes and will not be presented.  Additional analysis may be performed if 
warranted upon review of the data.

3. Introduction
3.1.
Study Rationale
Absolute bioavailability data are required by regulatory agencies in some geographical areas.  
Knowledge of absolute bioavailability is helpful in the interpretation of pharmacokinetic (PK)
data, and may be helpful in the design of clinical pharmacology studies.
3.2.
Background
LY3314814, also known as AZD3293, is a brain-permeable inhibitor of human beta-site amyloid 
precursor protein cleaving enzyme 1 being developed to slow disease progression in patients 
with early Alzheimer’s disease (AD) (defined as the continuum of mild cognitive impairment 
due to AD and mild dementia of the Alzheimer’s type).  
Clinical Experience
3.2.1.
As of 28 November 2016, approximately 429 subjects/patients have been exposed to LY3314814
in completed Phase 1 trials, of which 417 were healthy subjects and 12 were patients with AD.  
Single oral doses ranging from 1 to 750 mg and multiple daily doses up to 150 mg were explored 
in 11 completed clinical pharmacology studies. 
An additional Phase 1 trial (I8D-MC-AZEB) evaluating the effect of LY3314814 on rosuvastatin 
in healthy subjects and 3 Phase 3 trials (Study I8D-MC-AZET, Study I8D-MC-AZES, Study
I8D-MC-AZFD) evaluating daily doses of 20 mg and 50 mg LY3314814 in patients with mild 
cognitive impairment and mild AD dementia, are currently ongoing.
LY3314814 has not previously been administered as an intravenous (IV) dose.
3.2.1.1.
Clinical Pharmacokinetic Data
LY3314814 PK have been evaluated following single oral doses of 1 to 750 mg and at 
steady-state from 15 to 150 mg.  Following oral dosing, LY3314814 time of maximum observed 
drug concentration (tmax) is approximately 1 to 2 hours postdose and then follows a 
bi-exponential elimination profile.  The LY3314814 half-life associated with the terminal 
elimination phase (t1/2) is approximately 18 hours.  Upon multiple dosing, exposure increases 
modestly with an accumulation ratio of approximately 1.46, based on area under the drug 
concentration-time curve (AUC).  Steady-state appears to be achieved 4 to 8 days following the 
initiation of dosing, consistent with LY3314814 t1/2.  Over the dose range from 15 to 150 mg, 
the PK of LY3314814 appears dose proportional.  No meaningful differences in PK have been 
observed between young and elderly healthy subjects, or between healthy subjects and patients 
with AD.  Renal clearance was approximately 1.0 to 1.5 L/h 5% to 10% of total body clearance), 
suggesting that renal clearance is a minor elimination pathway.  A food effect study was 
completed demonstrating that administration of 50 mg LY3314814 with food resulted in a 
minimal (approximately 17%) reduction in maximum observed drug concentration (Cmax),
although AUC was not impacted. These results suggest that food reduces the rate, although not 
the extent, of absorption.  The PK results for the major metabolite AZ13569724 mirrored those 
of the parent.

I8D-MC-AZEP(d) Clinical Pharmacology Protocol
Page 13
LY3314814
LY3314814 is a substrate of CYP3A, as shown by drug interaction studies where strong 
inhibitors of CYP3A activity increased LY3314814 exposure by up to 2.85-fold. LY3314814
co-administration resulted in minor changes in exposure of the sensitive CYP3A4 substrate 
midazolam, suggesting that there is no clinically-meaningful effect of LY3314814 on CYP3A 
activity.
In vitro data suggests that LY3314814 is a substrate and inhibitor of Pgp.  A regimen of 50 mg 
LY3314814 once daily increased dabigatran mean AUC from zero to infinity (AUC[0-∞]) and 
Cmax by 15% and 17%, respectively, when a single 150-mg dose of dabigatran etexilate
(P-glycoprotein [Pgp] substrate) was administered at the same time as LY3314814 in healthy 
subjects.  These data suggest that LY3314814 is a relatively modest inhibitor of Pgp.  
Additional information regarding LY3314814 PK may be found in the Investigator’s Brochure 
(IB).
3.2.1.2.
Clinical Safety Data
No clinically significant safety or tolerability concerns have been identified to date in the 
LY3314814 Phase 1 program up to the highest dose given (750-mg single dose; 150-mg daily 
dosing for up to 12 days).  Across the 11 completed studies as of 28 November 2016, 2 serious 
adverse events (SAEs) were reported in 2 patients (severe ventricular tachycardia in a patient 
with a previously undisclosed cardiomyopathy, and cellulitis).  Both SAEs were judged by the 
investigator as not related to LY3314814.  
In completed studies, the most frequent treatment-emergent adverse events (TEAEs) reported by 
healthy subjects and patients with AD during LY3314814 treatment or wash-out (occurring in 
1% to 10% of subjects) periods include headache, orthostatic hypotension, dizziness, 
constipation, back pain, rash, dry skin, diarrhea, nausea, and pruritus. In general, there have 
been no clinical laboratory or ECG safety concerns identified in the completed Phase 1 studies.
Safety reviews of the ongoing Phase 3 trials are completed by an Independent Data Monitoring 
Committee (IDMC) which meets quarterly.  The recommendations of the IDMC at all meetings 
thus far for each study have been to continue without any modification.
More information about the known and expected benefits, risks, and reasonably anticipated AEs 
may be found in the IB.  
3.3.
Benefit/Risk Assessment
Study AZEP will include standard safety assessments, including spontaneous reporting of AEs, 
clinical laboratory tests, 12-lead ECGs, vital signs and physical examinations. Additionally, 
there are exclusion criteria in the protocol designed to prevent enrollment of subjects who may 
be at increased risk of potential adverse effects.
Potential risks of LY3314814 identified from non-clinical studies or completed phase 1 studies
include, but are not limited to, elevated liver enzymes, QT-prolongation in overdose, 
hypopigmentation of skin or hair, rash, retinal changes, and potential interactions with other 
drugs, including simvastatin, and strong CYP3A inducers or inhibitors, strong Pgp inducers or 
inhibitors, and BCRP inhibitors or inducers.  Of note, no LY3314814-related effects on male 

I8D-MC-AZEP(d) Clinical Pharmacology Protocol

LY3314814
reproductive potential were identified in rats.  No additional safety signals or potential risks have 
been identified to date during Phase 3 development.
Overall, in the opinion of the sponsor, Study AZEP has been carefully designed to safeguard 
participants against potential risks. Although no benefit is expected for the healthy subjects 
participating in this study, the information obtained from this study will benefit the development 
of this molecule and patients with AD who may use this molecule for therapeutic benefit in the 
future, for whom there are currently no approved disease-modifying treatments.
More information about the known and expected benefits, risks, SAEs, and reasonably 
anticipated AEs of LY3314814 may be found in the IB.

bioavailability of LY3314814 in healthy male and female subjects not of childbearing potential.
Each subject will provide informed consent for study participation and will undergo a screening 
examination within 28 days prior to enrollment.  
Subjects will be admitted to the clinical research unit (CRU) on Day -1 and will remain resident 
in the CRU for at least 48 hours after the start of infusion, followed by outpatient visits on Days
4, 5, 6, and 7 (follow-up visit).  On Day 1, following an overnight fast of at least 8 hours, 
subjects will receive a single oral dose of 50 mg LY3314814 and at approximately the same time 
an IV infusion of approximately 100 g [13C4
15N3]-LY3314814 will be started.  The infusion will 
run for 2 hours.  Blood samples will be collected predose and up to 120 hours postdose to 
measure LY3314814, and [13C4
15N3]-LY3314814 concentrations.  During the infusion and for at 
least 4 hours post-infusion, the PK blood samples will be taken from the arm contralateral to the 
infusion site.  A follow-up visit will occur at least 7 days postdose.
Safety and tolerability will be assessed throughout the study by means of vital sign 
measurements, clinical laboratory tests, ECGs, physical examinations (as indicated), and AE 
recording.
5.2.
Number of Participants
Up to 8 subjects may be enrolled and dosed to ensure that at least 6 subjects complete and have 
evaluable PK data.
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
This study will be open-label as the primary endpoint is objective rather than subjective; 
therefore, investigators and subjects do not need to be blinded.
The label or tracer method allows simultaneous oral and IV dosing which provides less 
variability in the absolute bioavailability estimate, and ensures the systemic clearance is 
equivalent for the IV and oral doses.  
The IV dose of [13C4
15N3]-LY3314814 will be administered at a constant rate of infusion over 
2 hours duration, so that the end of the IV dose occurs approximately at the tmax of the 
LY3314814 oral dose.  

I8D-MC-AZEP(d) Clinical Pharmacology Protocol

5.5.
Justification for Dose
An oral dose of 50 mg LY3314814 was selected based on current clinical data.  LY3314814 
doses up to 750 mg were well tolerated in the single ascending dose study.  The 50-mg dose of 
LY3314814 selected for this study is the highest dose that is being used in the ongoing Phase 3
studies.
The approximate 100-μg dose of [13C4
15N3]-LY3314814 to be delivered intravenously is 0.20%
of the 50-mg oral dose and is expected to have minimal impact on exposure and tolerability.  
This small fraction of the oral dose obviates the need for toxicology studies with IV 
administration.  In addition, the IV dose is within the anticipated sensitivity that can be achieved 
using liquid chromatography-tandem mass spectrometry (LC/MS/MS) for the tracer.  The 2-hour 
infusion duration is intended to align the oral and IV tmax (at 2 hours).

6. Study Population
Eligibility of subjects for study enrollment will be based on the results of screening medical 
history, physical examination, vital signs, clinical laboratory tests, and safety ECG.  
The nature of any conditions present at the time of the physical examination and any preexisting 
conditions will be documented.
Screening may 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.

Blinding
This is an open-label study.
7.4.
Dose Modification
Dose adjustments are not allowed for this study.
Special Treatment Considerations
7.4.1.
7.4.1.1.
Premedication for Infusions
Premedication for the infusion is not planned.  However, if an infusion reaction occurs, 
appropriate medication may be used as determined by the study investigator.  
7.4.1.2.
Management of Infusion Reactions
The risk of an infusion reaction is anticipated to be small; however, because this is the first 
administration of IV [13C4
15N3]-LY3314814, all subjects should be monitored closely.
Symptoms and signs that may occur as part of an infusion reaction include, but are not limited to, 
fever, chills, nausea, headache, bronchospasm, hypotension, angioedema, throat irritation, rash, 
pruritus, myalgia, and dizziness.  In the event that a significant infusion reaction occurs, the 
following guidance should be followed:

the investigational product infusion should be slowed or stopped, depending on the 
symptoms/signs present
o
if slowed, the infusion should be completed at the slower rate, as tolerated
o
if stopped, no further attempts to administer the investigational product will be 
made

I8D-MC-AZEP(d) Clinical Pharmacology Protocol
Page 24
LY3314814
o
supportive care should be employed in accordance with the symptoms/signs
7.4.1.3.
Safety Protocol in the Event of a Retrospective Positive Sterility Finding 
from Extemporaneously Prepared Study Treatment
If a positive sterility finding arises in the terminally sterile filtered product, the subjects who 
were dosed from the impacted batch should be immediately contacted and asked to return to the 
CRU for a full medical examination. This should include a physical examination/medical 
assessment, including blood pressure, pulse rate, and body temperature. Blood samples should 
be collected for culture and assayed for inflammatory markers such as C-reactive protein and 
elevations in white blood cell counts. If the signs and symptoms indicate a subject is suffering 
from possible infection(s), they will be clinically managed, treated, and followed up until 
resolution. Any AEs will be recorded as appropriate.
7.5.
Preparation/Handling/Storage/Accountability
Only participants enrolled in the study may receive investigational product and only authorized 
site staff may supply or administer study treatment.  All study treatments 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).
The [13C4
15N3]-LY3314814 solution for IV infusion will be prepared at the study site.  Details of 
the preparation and storage of the IV solution will be provided in separate instructions to the site.
7.6.
Treatment Compliance
The investigational product will be administered at the clinical site, and documentation of 
treatment administration will occur at the site.
7.7.
Concomitant Therapy
Drugs or substances that are known strong inducers or inhibitors of CYP3A, strong inhibitors or 
inducers of Pgp, or inhibitors of BCRP are specifically excluded within 14 days prior to the 
administration of study drug and during the study.  Additional drugs are to be avoided during the 
study unless required to treat an AE or for the treatment of an ongoing medical problem.
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).  Occasional acetaminophen (paracetamol) up to a 2-gram dose 
in a 24-hour period may be used at the discretion of the investigator.  Any additional medication 
used during the course of the study must be documented.
7.8.
Treatment after the End of the Study
Not applicable for this study.

8. Discontinuation Criteria
8.1.
Discontinuation from Study Treatment
Subjects who discontinue the investigational product early will have procedures performed as 
shown in the Schedule of Activities (Section 2).
Discontinuation of Inadvertently Enrolled Subjects
8.1.1.
If the investigator identifies a subject who did not meet enrollment criteria and was inadvertently 
enrolled prior to any dosing, the subject will be discontinued from the study with no further data 
collection or study procedures performed.  If the investigator identifies a subject who did not 
meet enrollment criteria and was inadvertently enrolled and dosed, the subject will be 
discontinued from the study and early discontinuation procedures performed.
8.2.
Discontinuation from the Study
Subjects will be discontinued in the following circumstances:

enrollment in any other clinical trial involving an investigational product 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 (GCP)

investigator decision
o
the investigator decides that the subject should be discontinued from the study

subject decision
o
the subject, requests to be withdrawn from the study
Subjects who discontinue the study early will have early discontinuation 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.

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 4 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.
Investigators must document their review of each laboratory safety report.
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.
The investigator remains responsible for following, through an appropriate health care option, 
AEs that are serious or otherwise medically important, considered related to the investigational 
product or the study, or that caused the subject to discontinue the investigational product 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 (ICF) is signed, study site personnel will record, via eCRF, the 
occurrence and nature of each subject’s preexisting conditions, including clinically significant 
signs and symptoms of the disease under treatment in the study.  Additionally, site personnel will 
record any change in the condition(s) and the occurrence and nature of any AEs.  
Any clinically significant findings from ECGs, labs, vital sign measurements, and other 
procedures should be reported as an AE to Lilly or its designee.
The investigator will interpret and document whether or not an AE has a reasonable possibility 
of being related to study treatment or a study procedure, taking into account the concomitant 
treatment or pathologies.  
A “reasonable possibility” means that there is a cause and effect relationship between the 
investigational product, study device, and/or study procedure and the AE.

I8D-MC-AZEP(d) Clinical Pharmacology Protocol
Page 27
LY3314814
Planned surgeries should not be reported as AEs unless the underlying medical condition has 
worsened during the course of the study.
If a subject’s investigational product is discontinued as a result of an AE, study site personnel 
must report this to Lilly or its designee via eCRF.
Serious Adverse Events
9.2.1.
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

events considered significant by the investigator based upon appropriate medical 
judgment
Study site personnel must alert Lilly, 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 begins 
after the subject has signed informed consent and has received investigational product.  
However, if an SAE occurs after signing informed consent, but prior to receiving investigational 
product, 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 investigational product) 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.
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 identifies as related to investigational product or procedure.  
United States 21 Code of Federal Regulations 312.32 and European Union Clinical 
Trial Directive 2001/20/EC and the associated detailed guidances or national regulatory 

I8D-MC-AZEP(d) Clinical Pharmacology Protocol
Page 28
LY3314814
requirements in participating countries require the reporting of SUSARs.  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.
Complaint Handling
9.2.2.
Lilly will forward product complaints on LY3314814 to AstraZeneca 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 investigational product so that the situation can be assessed.
The investigator or his/her designee is responsible for handling the following aspects of the 
product complaint process in accordance with the instructions provided for this study:

recording a complete description of the product complaint reported and any associated 
AEs

communicating the product complaint 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 correspondence with the product.
9.3.
Treatment of Overdose
For the purposes of this study, an overdose of LY3314814 is considered any dose higher than 
planned.  There is no specific antidote for LY3314814.  In case of known or suspected overdose, 
monitoring of cardiac and hepatic effects and appropriate standard supportive therapy should be 
initiated as clinically indicated.
9.4.
Safety
Laboratory Tests
9.4.1.
For each subject, clinical laboratory tests detailed in Appendix 2 should be conducted according 
to the Schedule of Activities (Section 2).  
Vital Signs
9.4.2.
For each subject, vital sign measurements should be conducted according to the Schedule of 
Activities (Section 2).  
Supine blood pressure and pulse rate should be measured after at least 5 minutes supine rest.  .
Unscheduled orthostatic vital signs should be assessed, if possible, during any AE of dizziness or 
posture-induced symptoms.  Additional vital signs may be measured during study if clinically
indicated or at the investigator’s discretion.
Body temperature will be measured as specified in the Schedule of Activities (Section 2) and as 
clinically indicated.

I8D-MC-AZEP(d) Clinical Pharmacology Protocol
Page 29
LY3314814
Electrocardiograms
9.4.3.
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.  All ECGs recorded should be stored at the 
investigational site.
Electrocardiograms will be interpreted by a qualified investigator (or 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 or 
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 new clinically relevant finding should be 
reported to Lilly, or its designee, as an AE.  
Physical Examination
9.4.4.
Physical examinations and medical review with targeted examinations will be conducted as 
specified in the Schedule of Activities (Section 2) and as clinically indicated.  
Body Weight
9.4.5.
Body weight will be recorded as specified in the Schedule of Activities (Section 2) and as 
clinically indicated.
Safety Monitoring
9.4.6.
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 consult with the functionally independent Global Patient Safety therapeutic area 
physician or clinical research scientist when appropriate, and periodically review:

trends in safety data

laboratory analytes 

AEs
In the event a subject experiences a suspected drug-induced rash, the following procedures 
should be followed:

The subject should be referred to a dermatologist for an expert opinion.

A photograph of the rash should be taken.

I8D-MC-AZEP(d) Clinical Pharmacology Protocol
Page 30
LY3314814

A blood sample should be drawn for PK analysis, if >12 hours since the last PK sample.
If treatment is discontinued due to a suspected drug-induced rash, the Lilly-designated medical 
monitor should be notified as soon as possible, even if the rash did not meet the definition of an 
SAE.
9.4.6.1.
Hepatic Safety
If a study subject experiences elevated ALT ≥3X ULN, ALP ≥2X ULN, or elevated total 
bilirubin ≥2X ULN, liver tests (Appendix 4) should be repeated within 3 to 5 days including 
ALT, AST, ALP, TBL, direct bilirubin, gamma-glutamyl transferase (GGT), 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 clinical pharmacologist 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 ≥ [5X] ULN on two or more consecutive blood tests

elevated serum TBL to ≥[2X] ULN (except for cases of known Gilbert’s 
syndrome)

elevation of serum ALP to ≥ [2X] ULN on 2 or more consecutive blood tests 

subject discontinued from treatment due to a hepatic event or abnormality of liver 
tests

hepatic event considered to be a SAE
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 plasma concentrations of 
LY3314814, and [13C4
15N3]-LY3314814.  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 24-hour clock time of each sampling will be 
recorded.
Bioanalysis
9.5.1.
Samples will be analyzed at a laboratory approved by the sponsor and stored at a facility 
designated by the sponsor.
Concentrations of LY3314814, and [13C4
15N3]-LY3314814 will be assayed using a validated 
LC/MS/MS method.  
Bioanalytical samples collected to measure investigational product concentrations will be 
retained for a maximum of 2 years following last subject visit for the study.  During this time, 
samples remaining after the bioanalyses may be used for exploratory analyses such as 
metabolism and/or protein binding work.

Pharmacodynamics
This section is not applicable for this study.
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 response to LY3314814 and to 
investigate genetic variants thought to play a role in AD.  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 ethical review boards (ERBs) 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 LY3314814 or after LY3314814 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
Up to 8 subjects may be enrolled and dosed to ensure that at least 6 subjects complete and have 
evaluable PK data.
This sample size is considered adequate for Phase 1 studies evaluating absolute bioavailability 
and is not intended to meet any a priori statistical requirement.
10.2. Populations for Analyses
Study Participant Disposition
10.2.1.
A detailed description of subject disposition will be provided at the end of the study. All 
subjects who discontinue from the study will be identified, and the extent of their participation in 
the study will be reported.  If known, a reason for their discontinuation will be given.
Study Participant Characteristics
10.2.2.
The subject’s age, sex, weight, height, BMI, race/sub-race, tobacco/nicotine habits, or other 
demographic characteristics will be recorded and may be used in the PK and safety analyses as 
quantitative or classification variables.
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 subjects receiving the investigational product and who have evaluable data.  If a subject 
has an AE of vomiting that occurs at or before 2 times median tmax after dosing then that subject 
may be excluded from the PK summary statistics and statistical analysis.  Safety analyses will be 
conducted for all enrolled subjects, whether or not they completed all protocol requirements.
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.  
Safety Analyses
10.3.1.
10.3.1.1. Clinical Evaluation of Safety
All investigational product and protocol procedure AEs 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 investigational product as perceived by the investigator.  Symptoms reported to occur prior 
to enrollment 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.

I8D-MC-AZEP(d)Clinical Pharmacology Protocol
Page 33
LY3314814
The number of investigational product-related SAEs will be reported.
10.3.1.2.Statistical Evaluation of Safety
Safety parameters that will be assessed include clinical lab parameters, vital signs, and ECGs.  
The clinical lab parameters will be listed.  Vital signs will be listed and summarized using 
standard descriptive statistics.  Electrocardiogramsand physical examinationswill be performed 
for safety monitoring purposes and will not be presented.  Additional analysis maybe performed 
if warranted upon review of the data.
Pharmacokinetic Analyses
10.3.2.
10.3.2.1.Pharmacokinetic Parameter Estimation
Pharmacokinetic parameter estimates for LY3314814, and [
13C4
15N3]-LY3314814will be 
calculated by standard noncompartmental methods of analysis.
The primary parameters for analysis will beAUC(0-∞) and AUC(0-t
last).  Secondary
 parameters 
will be Cmax, t
max, and t
1/2.  Other noncompartmental parameters, such as total body clearance 
of drug calculated after IV administration(CL), apparent clearance(CL/F), apparent volume of 
distribution during the terminal phase(Vz and Vz/F), and apparent volume of distributionat 
steady state (V
ssand Vss/F),may be reported.
The absolute bioavailability of LY3314814 will be calculated using the LY3314814 AUC 
estimates calculated after oral dosing with LY3314814 and IV administration of
[
13C4
15N3]-LY3314814, with adjustment for dose.
10.3.2.2.Pharmacokinetic Statistical Inference
To quantify the absolute bioavailability of LY3314814, a mixed-effect analysis of variance 
model will be applied to the log-transformed dose-adjusted AUC of LY3314814 obtained after 
oral dosing and that of the IV administered [
13C4
15N3]-LY3314814.  The model will contain 
formulation (oral or IV) as a fixed effect and subject as a random effect.  The absolute 
bioavailability will be expressed as the ratio of the least-squares geometric means of the 
formulations (oral :IV) along with its corresponding 90% confidence interval.
The PK parameter estimates for LY3314814, and [
13C4
15N3]-LY3314814will be summarized 
using appropriate descriptive statistics.
Additional analysis maybe conducted if deemed appropriate.
Interim Analyses
10.3.3.
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 
An Absolute Bioavailability Study of LY3314814 in 
Healthy Subjects Using an Intravenous Tracer Method
Protocol I8D-MC-AZEP, An Absolute Bioavailability Study of LY3314814 in Healthy Subjects 
Using an Intravenous Tracer Method, has been amended. The new protocol is indicated by 
Amendment (d) and will be used to conduct the study in place of any preceding version of the 
protocol.
The protocol now states that 
If the investigator identifies a subject who did not meet enrollment criteria and was inadvertently 
enrolled prior to any dosing, the subject will be discontinued from the study with no further data 
collection or study procedures performed.  If the investigator identifies a subject who did not 
meet enrollment criteria and was inadvertently enrolled and dosed, the subject will be 
discontinued from the study and early discontinuation procedures performed (Section 8.1.1.).

Revised Protocol Sections
Note:
All deletions have been identified by strikethroughs.
All additions have been identified by the use of underscore.
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 with or without continued treatment 
with investigational product.
If the investigator identifies a subject who did not meet enrollment criteria and was inadvertently 
enrolled prior to any dosing, the subject will be discontinued from the study with no further data 
collection or study procedures performed.  If the investigator identifies a subject who did not 
meet enrollment criteria and was inadvertently enrolled and dosed, the subject will be 
discontinued from the study and early discontinuation procedures performed.
