1. Synopsis 
Title of Study:   
A Phase 2, Double-Blind, Placebo-Controlled, 3-Month Trial of LY3298176 versus Placebo in 
Patients with Type 2 Diabetes Mellitus 
Rationale:   
Study I8F-MC-GPGF is a 3-month Phase 2 study designed to examine the efficacy and 
tolerability of subcutaneously administered once-weekly (QW) LY3298176 compared with 
placebo in patients with type 2 diabetes mellitus (T2DM) who have inadequate glycemic control 
with diet and exercise alone or with a stable dose of metformin.  This study will use 3 different 
titration schemes of LY3298176 to reach the highest planned dose.  The primary endpoint will be 
the change from baseline in hemoglobin A1c (HbA1c) at the end of study drug treatment.  
Efficacy and tolerability data from this study and from the large Phase 2 study I8F-MC-GPGB 
(GPGB) will be used to set doses and titration scheme for the Phase 3 studies. 
Objectives/Endpoints:   
Objectives 
Endpoints 
Primary 
 To demonstrate that at least 1 LY3298176 titration 
scheme is superior to placebo in hemoglobin A1c 
(HbA1c) reduction at 3 months in patients with type 2 
diabetes mellitus (T2DM) inadequately controlled 
with diet and exercise alone or treated with a stable 
dose of metformin 
 
 Change in HbA1c from baseline 
Secondary 
Efficacy 
 To compare each titration scheme to placebo at 
3 months for secondary efficacy parameters 
 
 
 Proportion of patients achieving HbA1c target of 
<7.0%  
 The change in fasting blood glucose (FBG; central 
laboratory) from baseline  
 The change in body weight from baseline  
 The change in waist circumference from baseline 
Safety 
 To compare each titration scheme to placebo for 
selected safety parameters at 3 months 
 
 Treatment-emergent adverse events (TEAEs) and 
serious adverse events (SAEs) 
 Incidence of nausea, vomiting, and diarrhea 
 Discontinuation of study drug due to adverse events 
(AEs) 
 Incidence and rate of hypoglycemia (severe, total, 
documented symptomatic, and nocturnal) 
 Incidence of anti-LY3298176 antibodies 
Pharmacokinetics  
 To evaluate the pharmacokinetics (PK) of LY3298176 
 
 PK trough samples

Summary of Study Design:
LY3298176 is being investigated for its potential use in the treatment of T2DM.  LY3298176 is 
a long-acting, dual incretin receptor co-agonist that binds to both the glucose-dependent 
insulinotropic polypeptide (GIP) receptor and the glucagon-like peptide-1 (GLP-1) receptor.  
Study GPGF is a Phase 2, multicenter, randomized, double-blind, parallel-arm, placebo-
controlled titration study designed to evaluate efficacy, tolerability, and safety of LY3298176 in 
patients with T2DM with inadequate glycemic control on diet and exercise alone or on a stable 
dose of metformin monotherapy.  
Treatment Arms and Duration:
Study GBGF includes 4 treatment arms: 3 titration arms of LY3298176 and matching placebo.
Patients will be randomized in a 1:1:1:1 ratio to 1 of the 3 LY3298176 titration groups or 
placebo. Study participants will be treated for 3 months after randomization in a double-blind 
manner, followed by a 4-week safety evaluation. 
Number of Patients:
A total of approximately 92 patients (23 patients per titration group or placebo) will be 
randomized, and approximately 80 are expected to complete the treatment period.  
Statistical Analysis:
Efficacy:  The primary analysis for the endpoint of the primary objective, change from baseline 
in HbA1c at 3 months, will be mixed model for repeated measures (MMRM) analysis. It will be 
performed on the modified intent-to-treat (mITT) analysis data set.  This model will include
baseline body mass index (BMI; <30, 30), metformin use, treatment, visit, and treatment-by-
visit as fixed effects, and baselineHbA1c value as a covariate.  
Additional covariates may be added and will be detailed in the statistical analysis plan (SAP).
The mean weight change from baseline at 3 months will be analyzed using similar MMRM
models as the primary analysis with treatment, visit, treatment-by-visit, metformin use, baseline 
HbA1C category (<8.5%, ≥8.5%) as fixed effects, and baseline body weight as covariate.  The 
change from baseline of fasting blood glucose (FBG) and waist circumference will be analyzed 
using a similar MMRM-based model.  Summaries will include descriptive statistics for 
continuous measures (sample size, mean, standard deviation [SD], median, minimum, and 
maximum) and for categorical measures (sample size, frequency, and percentage).
Safety:  The summary statistics for continuous variables will be sample size, mean, SD, median, 
minimum, and maximum.  The summary statistics for categorical variables will be sample size, 
frequency, and percentage.  Exposure to each therapy during the treatment period of the study 
will be calculated for each patient and summarized by treatment group.  Additional analyses, 
such as concentration–safety lab plots, may be performed if warranted upon review of the data. 
Pharmacokinetics (PK)/Pharmacodynamics (PD):  Trough PK samples collected over the course 
of this study will be used to assess that LY3298176 exposures in the study are consistent with
known LY3298176 PK. Additionally, PK/PD data from this study may be used as a validation 
dataset to enable evaluation of PK/PD models developed from the core Phase 2 study GPGB

data. These analyses may be conducted using nonlinear mixed-effects modeling implemented
with the NONMEM software. If positive antibody titers to LY3298176 are observed, the 
relationship between antibody titer and LY3298176 PK or any relevant PD parameters will be 
evaluated.

a Telephone visits occur during the week following a dose escalation and should be done 3 to 6 days after a site visit for dose escalation and administration.  At 
telephone visits, the sites should call the patient, ask how the patient is, and ask whether the patient would like to come to the site for assistance with the next 
study drug dilution and administration.  Sites should also remind patients to write down any AEs in their diaries at the telephone visits (as well as at all site 
visits). 
b Visit should occur approximately 1 week after the last dose (Dose 12). 
c Additional physical examinations may be performed throughout the study if determined necessary due to patient symptoms. 
d Visit should occur 4 weeks after the last dose of study drug or 3 weeks after Visit 10. 
e ECGs should be collected prior to all blood draws and study drug administrations.  Local ECGs will be collected for screening (Visit 1) and Early 
Termination.  Centralized ECGs, collected in supine position and in triplicate, should be collected for all other designated visits. 
f Screening laboratory tests include serum hepatitis B surface Ag, hepatitis C antibody (Ab), and human immunodeficiency virus (HIV) Ab tests for all patients 
(see Appendix 2). 
g Serum pregnancy test will be performed by central laboratory at Visit 1 for women of child-bearing potential.  For the remainder of the study, a urine 
pregnancy test may be performed at the investigator’s discretion if pregnancy is suspected during the study (local laboratory).  A urine pregnancy test (local) 
should be given to all women of child-bearing potential at Visit 3 prior to administration of first dose of study drug to confirm lack of pregnancy. 
h Collect serum FSH in women whose menopausal status needs to be determined.

3. Introduction  
3.1. Study Rationale 
Study I8F-MC-GPGF (GPGF) is a 3-month Phase 2 study designed to examine the efficacy, 
safety, and tolerability of subcutaneously administered once-weekly (QW) LY3298176 
administered in 3 different titration schemes compared with placebo in patients with type 2 
diabetes mellitus (T2DM) who have inadequate glycemic control with diet and exercise alone or 
with a stable dose of metformin monotherapy.  The primary endpoint will be the change in 
hemoglobin A1c (HbA1c) at the end of study drug treatment.  These data will support selection 
of doses and a titration scheme to attain the highest dose for Phase 3 trials.

5. Study Design
5.1.
Overall Design
Study GPGF is a randomized, multicenter, placebo-controlled, double-blind, parallel arm, Phase 
2 titration study in T2DM patients who have inadequate glycemic control with diet and exercise 
with or without a stable dose of metformin monotherapy. The study is designed to measure the 
change in HbA1c at the end of study treatment compared with placebo.  These data will support 
dose selection and the optimal titration scheme that minimizes GI-related AEs for Phase 3 trials.
The study will consist of 3 treatment periods: approximately 1-week lead-in period, followed by 
a 3-month treatment period, and a 4-week safety follow-up period (see Figure GPGF.1).  A
double-dummy dose administration scheme will be employed to ensure patients and investigators 
(as well as sponsor study team and monitors) remain blind to the LY3298176 and placebo
treatment assignments within each titration group.

LY3298176
Study Period I (Screening and Lead-In):
Screening (Visit 1)
Throughout the study, patients treated with metformin will remain on the same dose they were 
receiving at Visit 1 unless changes need to be made for safety reasons.  All patients will be 
encouraged to maintain their prestudy diet and exercise levels through the course of the study.
The purpose of screening procedures at Visit 1 is to establish initial eligibility (see Section 6) and 
to obtain blood samples for laboratory assessments needed to confirm eligibility.  Patients who 
meet all applicable inclusion criteria and none of the applicable exclusion criteria at Visit 1 will 
continue on to Visit 2.
Lead-In (Visit 2 to Visit 3)
During the lead-in period, eligible patients should continue their prestudy therapy, metformin 
(same formulation and dose), in order to allow reliable assessment of HbA1c at baseline 
(Visit 3).  During the lead-in period, patients will be trained on disease monitoring and disease 
management procedures, glucometer use, study diaries, and study procedures.  Patients will 
receive training on routine blood glucose monitoring and paper diary completion required during 
the study.  Patients should follow the investigator’s instructions related to frequency of blood 
glucose testing but should test their glucose a minimum of 3 times per week.  Patients will also 
be required to conduct a 7-point self-monitoring glucose test (SMBG) prior to randomization 
(Visit 3) and return the results in their diary at Visit 3 (see Section 9.1.2.1). Patients will also
receive education on how to dilute study drug in the vials, perform SC injections, appropriate 
injection site locations, injection technique, and the signs and symptoms of local adverse 
reactions including injection site reactions.  Patients will receive instructions on timing of doses
(Table GPGF.3 and Section 7.1), and will be instructed to record the date and time of all 
injections administered throughout the study in their study diaries.  Study site staff will observe 
each patient diluting the study drug vials and self-injecting for training purposes at all site visits 
beginning with Visit 3.  
Visit-specific subject diaries will be dispensed at Visit 2 and at each visit thereafter, until the last 
study visit (see Schedule of Activities, (Section 2).  Patients should be instructed to record all 
AEs in their diaries.
Study Period II (Treatment Period):
Randomization (Visit 3)
At Visit 3, patients will undergo study procedures that are required prior to randomization.
Patients who continue to be eligible will then be randomized in a 1:1:1:1 ratio to 1 of the titration 
schemes (Group 1, Group 2, or Group 3) or placebo.  Placebo patients will be distributed within 
each titration group in order to maintain treatment blinding.  After randomization, the patient will 
dilute the study drug vial and inject the first dose of study drug while at the study site.  Although 
patients will be diluting study drug and injecting themselves at home between study site visits, 
they will be required to dilute the vials and inject themselves under the supervision of site 

I8F-MC-GPGF Clinical Protocol
Page 21
LY3298176
personnel at every scheduled site visit.  However, unscheduled visits to help patients with 
diluting study drug in the vials and self-injecting are permitted whenever the patient needs or 
wants additional support.
Following randomization, patients will participate in a 3-month treatment period that consists of 
dose titrations to reach and maintain the highest scheduled dose level of LY3298176. 
Treatment Phase (Visit 3 to Visit 10)
During the treatment phase, the dose of LY3298176 will be escalated within each titration group 
according to 1 of 3 dose titration schedules as outlined in Figure GPGF.1.  
At each dosing time point, the study drug will be self-administered as 1 to 3 SC injections of 
LY3298176 or matched placebo (number of injections will be determined by where the patient is 
in the dose titration scheme) (see Section 7.1).  
The last treatment visit, Visit 10, will occur approximately 1 week after the last dose of study 
drug for collection of efficacy and safety parameters.
In addition to the clinic visits, 2 telephone visits will be scheduled during this period and will 
occur 3 to 6 days after a site visit for dose escalation and will be scheduled to occur prior to the 
next dose administration.  At the telephone visit, the site is to check on the patient and ask if the 
patient needs to come to the site for an unscheduled visit for help with diluting and self-injecting
the study drug.  Patients are also to be reminded to write down any AEs in their study diaries.  At 
each of the scheduled site visits, procedures will include assessments of study drug compliance, 
hypoglycemic events, concomitant medications, and AEs.  
General Considerations
At each visit, patients should be reminded to write down any AEs in their study diaries, including 
any events associated with self-injecting study drug when at the study site visit. 
Patients will undergo or perform study procedures listed in the Schedule of Activities 
(Section 2).  
Patients taking a stable dose of metformin at study entry will continue to use concomitant 
metformin throughout the treatment period.  Discontinuation or changes to dose are generally not 
permitted, except in the situations of patient safety (for further details, see Section 7.1).
Patients will be instructed to perform fasting blood glucose (FBG) measurements and to record 
all results in diaries; these results will be used for glucose management only.  
Patients who develop severe, persistent hyperglycemia based on prespecified thresholds (see 
Section 9.2.1.2.4) will receive a new glucose-lowering intervention (or rescue therapy) based on 
clinical judgment of the investigator, and the patient will discontinue study drug.  Patients who 
need rescue therapy for this reason will be asked to remain in the trial until they complete all 
study visits for collection of safety information.  Patients who discontinue study drug due to AEs 
will also be asked to continue in the trial for collection of safety information.  Patients who are 
unable or unwilling to continue in the study because of an AE or any other reason will perform 

I8F-MC-GPGF Clinical Protocol
Page 22
LY3298176
an early termination (ET) visit as their final study visit.  If the patient is discontinuing during an 
unscheduled visit, that visit should be performed as the ET visit.  If the patient is discontinuing 
during a scheduled visit, that visit should be considered the ET visit.  At this visit, patients will 
perform procedures listed in the Schedule of Activities (Section 2).
Study Period III (Safety Follow-Up, Visit 801):
All randomized patients who complete the treatment period will complete the safety follow-up 
approximately 4 weeks after their last visit on treatment.  
Patients randomized to LY3298176 who have treatment-emergent anti-LY3298176 antibodies or 
antibodies to native GIP or GLP-1 at the last visit may be monitored after the last visit (see 
Section 9.9).
5.2.
Number of Participants
Approximately 150 participants will be screened to achieve 92 randomized and 80 evaluable 
participants for an estimated total of 20 evaluable participants per treatment group.
5.3.
End of Study Definition
End of the trial is the date of the last visit or last scheduled visit shown in the Schedule of 
Activities (Section 2) for the last patient.
5.4.
Scientific Rationale for Study Design
Study GPGF is a 3-month Phase 2 study designed to evaluate the efficacy, safety, and tolerability 
of 3 different titration schemes of LY3298176 compared with placebo in patients with T2DM
inadequately controlled with diet and exercise with or without stable metformin monotherapy.
The titration algorithms to be used in Study GPGF have been chosen based on tolerability data 
from the Phase 1 study GPGA, and the highest dose and dose titration scheme being evaluated in 
the Phase 2 study GPGB.  Study GPGF is designed to explore titration schemes different from 
those in Study GPGB.  In Study GPGB, the 15 mg dose is attained using a dose titration of 5 mg 
for the first 2 weeks, followed by 10 mg for 4 weeks, before reaching 15 mg at Week 7.  This 
approach for titrating a drug with GLP-1 RA activity is expected to allow patients to reach the 
15 mg dose with minimal GI-related AEs.  However, there may be other titration schemes that 
that are superior for minimizing the GI-related AEs that were observed in the Phase 1 study 
GPGA at the 15 mg dose.  It is possible that giving patients a very low first dose of 2.5 mg may 
improve tolerability of higher doses; thus, a 2.5 mg dose will be utilized in Study GPGF.  Study 
GPGF also contains 1 titration scheme with the highest LY3298176 dose level of 12 mg.  The 
12 mg dose was chosen in order to compare the tolerability and efficacy of 12 mg with 15 mg.  
The 12 mg dose may provide efficacy similar to that of the 15 mg dose but with superior 
tolerability, and this titration scheme provides additional data for dose and dose titration 
decisions for Phase 3.  Efficacy, safety, and tolerability data from both Study GPGB and Study 
GPGF will be used to set doses and the titration scheme for the Phase 3 development program.

I8F-MC-GPGF Clinical Protocol

LY3298176
The current study will enroll patients with inadequate glycemic control based on HbA1c values 
ranging from 7.0% to 10.5%, inclusive.  Similar ranges of screening HbA1c have been used in 
numerous studies of T2DM treatments.
Patients treated with diet and exercise alone, or in combination with stable metformin 
monotherapy (1000 mg/day), will be enrolled.  Patients on a second oral antihyperglycemic 
medication (OAM) may also be eligible if the second OAM was discontinued 3 months prior to 
Visit 1 (refer to Section 6.2, Exclusion Criterion 35).  Stable metformin treatment for at least 
3 months is required to minimize glucose variability prior to study entry.
5.5.
Justification for Dose
The highest dose to be evaluated in Study GPGF is 15 mg, which is the highest dose being 
evaluated in the Phase 2 study GPGB.  Depending on the safety, tolerability, and efficacy data in 
Study GPGB, the LY3298176 15 mg dose may be the high dose tested in the Phase 3 program.  
The 15 mg dose was considered safe in the Phase 1 study GPGA although not well tolerated.  
Based on experience with other GLP-1 RAs, higher doses may be attained through dose titration 
to minimize GI-related AEs. The 3 titration schemes to reach either LY3298176 12 mg or 15 mg 
were selected based on the following:

Phase 1 tolerability data in T2DM patients utilizing the dose titration scheme of QW 
LY3298176 doses of 5 mg for the first 2 weeks, 10 mg for the third week, and 15 mg the 
fourth week showed that this titration scheme to reach 15 mg was too rapid and resulted 
in more incidents of vomiting following the 15 mg dose than had been observed with 
other titration schemes with lower LY3298176 doses.  Thus, a more gradual titration may 
be needed to reach 15 mg.

The current titration scheme for Study GPGB is LY3298176 5 mg for the first 2 weeks, 
followed by 10 mg for 4 weeks before reaching the first 15 mg dose at Week 7, and 
continuing on 15 mg for the duration of the study.  This titration scheme is expected to be 
tolerated; however, other titration schemes may have improved tolerability or patient and 
physician convenience.  This will be explored in different titration schemes in Study 
GPGF.

It is possible that a slightly lower dose (>10 mg but <15 mg) would have improved 
tolerability with comparable efficacy compared with 15 mg.  Therefore, LY3298176 
12 mg was chosen as the high dose for 1 titration scheme.

Prospective approval of protocol deviations to recruitment and enrollment criteria, also known as 
protocol waivers or exemptions, are not permitted.
6.1.
Inclusion Criteria
Patients are eligible to be included in the study only if they meet all of the following criteria at 
screening:
Type of Patient and Disease Characteristics
[1]
Have T2DM for at least 6 months before screening based on the disease 
diagnostic criteria (Appendix 5).
[2]
Have an HbA1c value at screening of 7.0% and 10.5% and treated with diet 
and exercise alone or a stable dose of metformin (either immediate release or 
extended release, 1000 mg/day and not more than the locally approved dose)
for at least 3 months prior to screening/Visit 1.  
Patient Characteristics
[3]
Male or female patients 18 to 75 years of age, inclusive.
[3a] Male patients:
Male patients should be willing to use reliable contraceptive methods 
throughout the study and for at least 3 months after last injection (see 
Appendix 6).
[3b] Female patients:
Women not of child-bearing potential may participate and include those 
who are:

infertile due to surgical sterilization (hysterectomy, bilateral oophorectomy, 
or tubal ligation), congenital anomaly such as mullerian agenesis; or

postmenopausal – defined as 
o
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
o
at least 6 months of spontaneous amenorrhea with a follicle-stimulating 
hormone (FSH) >40 mIU/mL; or
o
A woman 55 or older not on hormone therapy, who has had at least 
6 months of spontaneous amenorrhea; or
o
A woman at least 55 years of age with a diagnosis of menopause prior to 
starting hormone replacement therapy.
Women of child-bearing potential (not surgically sterilized and between 
menarche and 1-year postmenopausal) may participate.  In order to 
participate, they must:

I8F-MC-GPGF Clinical Protocol
Page 25
LY3298176

Women of child-bearing 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.

Otherwise, women of child-bearing potential participating must agree to use 
1 highly effective method (<1% failure rate) of contraception, or a 
combination of 2 effective methods of contraception for the entirety of the 
study:
o
Women of child-bearing potential must test negative for pregnancy prior 
to initiation of treatment as indicated by a negative serum pregnancy test 
at the screening visit and followed by a negative urine pregnancy test 
within 24 hours prior to exposure. (Any pregnancy testing subsequent to 
this initial test should be based on compound specific concerns and is 
not mandated by this guidance.)
o
Either 1 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.

Not be breastfeeding.

Lifestyle Restrictions
Study participants should be instructed not to donate blood or blood products during the study or 
for 60 days following the study.
6.4.
Screen Failures
Individuals who do not meet the criteria for participation in this study (screen failures) may be 
rescreened only once at the discretion of the investigator.  Before rescreening is performed, the 
patient must sign a new informed consent form (ICF) and receive a new identification number.  
If, in the opinion of the investigator, an ineligible lab test result is the result of an error or 
extenuating circumstance, then that parameter can be retested once (if feasible within the time 
constraints of the screening period) without the patient having to be rescreened.  However, 
screen failures for HbA1c may not be retested or rescreened.

7. Treatments
7.1.
Treatments Administered
In this study, patients will receive treatment with 1 of 3 LY3298176 titration schemes for 
3 months to assess the reduction in HbA1c compared with placebo.  The titration doses of 
LY3298176 will range from 2.5 mg through 15 mg to reach either 12 mg or 15 mg as the highest 
titrated maintained dose.  Study drug will be supplied as lyophilized drug in a vial and each vial 
will contain 5 mg.  There will be matching placebo vials.  Patients will receive 1 to 3 injections 
of study drug per week depending on which dose the patient is scheduled to receive in the
titration schedule.  At the highest dose attained, 12 mg or 15 mg, patients will receive 
3 injections per week (to be taken at the same time).  Each SC dose administration of study drug 
should be in different quadrants of the abdomen. If the recommendation following the first 
interim analysis of Study GPGB is to lower the highest dose of 15 mg to 12.5 mg, then the 
highest dose administered for Groups 1 and 2 of this study, GPGF, will also be lowered to 
12.5 mg from 15 mg.  The high dose for Group 3, 12 mg, will be unchanged.  If this change 
occurs, it will be prior to the first patient visit for Study GPGF.  Furthermore, patient user 
materials will be modified to indicate that the highest titrated LY3298176 dose for Groups 1 and 
2 will be 12.5 mg.
This study will involve dose titration in 2.5 mg, 4 mg, 5 mg, or 7.5 mg dose increments 
(Table GPGF.3).  Although the investigators and patients will know which titration group the 
patients are assigned, they will not know whether they are receiving LY3298176 or a 
complementary volume of placebo.
Patients will be required to dilute study drug in the vials and administer injections of the study 
drug or matching placebo at approximately the same time each week. The study site will send 
vials, diluent (Sterile Water for Injection), and syringes with needles home with patients.  For all 
clinical site visits, the patient should dilute the vials and administer the study drug at the clinical 
research site under the supervision of study personnel in order to reinforce patient understanding 
and confidence.  Patients will be diluting study drug in the vials and self-injecting at home 
during weeks without a clinical site visit and instructions will be provided.  The investigator or 
site staff may assist patients with vial reconstitution and study drug injection any time they deem 
necessary.

Abbreviation:  N/S= none scheduled.
Note:  For each of the groups, visits are scheduled to occur on the day of the next scheduled titrated dose.  For non-
scheduled visits, it is expected that the patient will dilute study drug and self-inject at home.  However, the 
investigator may have the patient come to the site for an unscheduled visit to dilute the vials and self-inject at any 
time the investigator feels that the patient would benefit from added instruction and supervision.  Visit 10 (not 
shown) will occur 1 week after the last dose of study drug (Dose 12).
Patients taking background metformin (either immediate release or extended release) are 
strongly encouraged to remain on the same type of metformin during the trial, if possible.  
Changing formulations or manufacturers of metformin during the study participation should be 
minimized.  If a dose change (ie, conversion of extended release to immediate release or vice 
versa) is required, the investigator should determine the most appropriate clinically equivalent 
metformin dose.  The metformin dose should be at least 1000 mg/day and not more than the 
highest dose allowed per local label.
The patient receiving metformin should continue the baseline dose of metformin, unless the 
patient experiences documented hypoglycemia, in which case the dose may be reduced.
The investigator or his/her designee is responsible for the following:

explaining the correct use of the investigational agents to the patient or the patient’s legal 
representative

verifying that instructions are followed properly

maintaining accurate records of investigational product dispensing and collection

at the end of the study returning all unused medication to Lilly, or its designee, unless the 
sponsor and sites have agreed that all unused medication is to be destroyed by the site, as 
allowed by local law.
Patients will be instructed to contact the investigator as soon as possible if he/she has a complaint 
or problem with the study drug so that the situation can be assessed.
7.1.1. Packaging and Labeling
Clinical trial materials will be labeled according to the regulatory requirements.  LY3298176 and 
the matched placebos will be supplied by Lilly.  
 
CCI

I8F-MC-GPGF Clinical Protocol
Page 33
LY3298176
 
 
 Patients will 
inject the dose volume appropriate for their treatment group, including placebo patients within a 
group.  LY3298176 vials must always be stored in a secure location with access limited to 
designated study staff members.
Instructions for the reconstitution of study drug will be provided separately to each patient and 
the investigator.  
 
  The reconstituted LY3298176 or placebo solution should be 
used immediately after reconstitution.
Study drug must be stored in a refrigerator at 2C to 8C (36F to 46F).  Temperature logs must 
be maintained to verify correct storage conditions at the investigator site, throughout the study. 
Patients should be instructed to store the study drug in their refrigerator but are not required to 
maintain temperature logs.  Sterile water vials may be stored at room temperature.
7.1.2. Medical Devices
The manufactured medical devices provided for patient use in the study are glucose meters and 
lancet devices.
7.2.
Method of Treatment Assignment
A unique 4-digit patient number will be assigned to each patient when the patient signs the ICF.
Patients will be assigned to placebo or 1 of 3 LY3298176 titration groups.  Patients who meet all 
criteria for enrollment will be randomized at Visit 3 and assigned to their respective treatment 
arms via IWRS using the following stratification variables: baseline HbA1c (<8.5%, 8.5%), 
metformin use (Yes, No), and BMI (<30, 30).  There will be approximately an equal 
randomization to the treatment arms (1:1:1:1).  
The randomization algorithm will be performed using IWRS that will ensure balance between 
treatment arms.
7.2.1. Selection and Timing of Doses
Assignment to 1 of 3 LY3298176 titration groups or placebo will occur at randomization.  There 
are no restrictions on the time of day each QW dose is given, but it is advisable to administer SC 
injections on the same day and same time each week. Patients should be instructed to record the 
actual date and time of all dose administrations in the diary provided.  The actual date and time 
of all dose administrations will be recorded in the subject’s case report form (CRF). If a dose of 
study drug, including placebo, is missed, the patient should take it as soon as possible and 
contact the study site for further instructions on timing of the next scheduled dose.
7.2.2.
Specific Restrictions/Requirements
Prior to beginning the study, patients will complete informed consent and baseline tests.
CCI
CCI

I8F-MC-GPGF Clinical Protocol
Page 34
LY3298176
Throughout the study, patients may undergo medical assessments and compliance reviewed 
before continuing in the study.
Patients will report to the clinical research site for safety assessments and will remain in the 
clinic until all procedures for that visit are complete and the investigator has deemed it safe to 
release the patient from the clinic.  There will be no inpatient stays.  
Meals/Diet – Patients shall fast for at least 8 hours overnight prior to each outpatient visit where
fasting samples are drawn or weight measurements taken.
Alcohol – Alcohol will not be permitted 8 hours prior to the dosing day, until the patient has 
been discharged from the clinical research site.
Exercise – Patients will be advised to maintain their regular levels of physical activity/exercise 
during the study.  When certain study procedures are in progress at the site, patients may be 
required to remain recumbent or sitting.
Blood donation – Study participants should be instructed not to donate blood or blood products 
during the study or for 8 weeks following the study.
Contraception – Male patients or their female partners of child-bearing potential must use 
reliable contraception during intercourse throughout the treatment period and for 3 months after 
the last dose of study drug as the risk of LY3298176 to the unborn fetus is unknown.  Female 
patients of child-bearing potential, if sexually active, should use 2 forms of effective 
contraception, where at least 1 form is highly effective for the duration of the trial and for
30 days thereafter. Please see Appendix 6 for further details regarding contraception.
7.3.
Blinding
This is a double-blind study.  Although the patient and the investigator will know which dose 
titration group (Group 1, Group 2, or Group 3) the patient is assigned to, they will not know 
whether the patient is receiving LY3298176 or placebo.
To preserve the blinding of the study, a minimum number of Lilly personnel will see the 
randomization table and treatment assignments before the study is complete.
Emergency codes, generated by a computer drug-labeling system, will be available to the 
investigator.  These codes, which reveal the patient’s treatment group when opened, may be 
opened during the study ONLY if the patient’s well-being requires knowledge of the patient’s 
treatment assignment.
Emergency unblinding for AEs may be performed through the IWRS, which may supplement or 
take the place of emergency codes generated by a computer drug-labeling system.  This option 
may be used ONLY if the patient’s well-being requires knowledge of the patient’s treatment 
assignment.  All calls resulting in an unblinding event are recorded and reported by the IWRS.
If an investigator, site personnel performing assessments, or patient is unblinded, the patient
must be discontinued from the study.  In cases where there are ethical reasons to have the patient

I8F-MC-GPGF Clinical Protocol
Page 35
LY3298176
remain in the study, the investigator must obtain specific approval from a Lilly clinical research 
physician (CRP)/clinical research scientist (CRS) for the patient to continue in the study.
In case of an emergency, the investigator has the sole responsibility for determining if unblinding 
of a patient’s treatment assignment is warranted for medical management of the event.  Patient 
safety must always be the first consideration in making such a determination.  If a patient’s 
treatment assignment is unblinded, Lilly must be notified immediately.  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.
Dosage Modification
Generally, no adjustment in study drug doses (LY3298176 or placebo) will be allowed.
However, if a patient is unable to tolerate a titrated dose for 2 weeks due to vomiting or moderate 
to severe nausea, the site should call the study CRS/CRP to discuss whether the patient should 
have the dose lowered to the previous dose level.  Dosing of required concomitant metformin is 
discussed in Section 7.7.
The highest dose of Groups 1 and 2, LY3298176 15 mg, may be reduced to 12.5 mg prior to first 
patient visit of this study, GPGF, if the first interim analysis of the large Phase 2 study GPGB 
indicates that the 15 mg dose is not well tolerated.  In that case, sites will be informed at the 
start-up meeting and in training materials.  Patients will be provided dosing instructions for the 
12.5 mg dose rather than the 15 mg dose.
7.5.
Preparation/Handling/Storage/Accountability
The study site must store the study drug in a locked and secure environment. The study drug 
must be refrigerated (not frozen) at 2C to 8C. Dry ice should not be used for cooling. Patients 
will be provided with double-blinded vials containing lyophilized LY3298176 or placebo and 
Sterile Water for Injection (along with syringes), at clinic visits according to the Schedule of 
Activities (Section 2). The patients will also receive insulated bags with cooling gel packs for 
use in transporting the study drug from the site to the home. Study drug in each participating 
country will be labeled according to the country’s regulatory requirements.
Commercial metformin may be made available during the treatment period to patients who 
entered the trial on this agent. Appropriate use and storage information will be available by 
referring to the package insert.
7.6.
Treatment Compliance
During the study, patients will be asked to return their study drug vials and completed diaries to 
the site so that their compliance may be assessed.
Patients who are significantly noncompliant will be permanently discontinued from study
medication.  A patient will be considered significantly noncompliant if he/she misses 2 doses of 
study medication.  Similarly, a patient will be considered significantly noncompliant if he/she is 

I8F-MC-GPGF Clinical Protocol
Page 36
LY3298176
judged by the investigator to have intentionally or repeatedly taken more or less than the 
prescribed amount of medication.
7.7.
Concomitant Therapy
Treatment with drugs that are excluded in the entry criteria (Section 6.2) is not permitted.
The only concomitant antihyperglycemic medication permitted during this study is metformin, 
unless glycemic criteria for rescue therapy are met (see Section 7.8.1).  Metformin treatment 
must be stable for at least 3 months prior to screening at a daily dose of 1000 mg/day.  Patients
who enter the study on diet and exercise alone will not be allowed to initiate metformin therapy 
after study entry unless criteria for rescue therapy are met.
Patients who are being treated with metformin upon entering this study should remain on the 
same (or equivalent if switching to sustained release) metformin dose throughout the course of 
the study unless a change in dose is required to protect patient safety.
If a patient switches from the immediate-release formulation of metformin to the 
sustained-release formulation, the change will be on a milligram-per-milligram basis.
In certain situations (such as during a hospitalization or perioperatively), it may be necessary for 
a patient to be treated with insulin(s).  Treatment with insulin will be allowed for up to 
14 consecutive days prior to or during the trial.  If a patient requires treatment with insulin for 
>14 consecutive days, that patient will be considered a “rescue” patient and may remain in the 
study but will not receive additional study drug.
Doses of antihypertensive and lipid-lowering therapies must be stable for 30 days prior to 
screening.  Doses of antihypertensive and lipid-lowering agents should not be changed during 
this study unless necessary to protect patient safety on an emergency basis (eg, hypertensive 
crisis).
Doses of other prescription medications (eg, thyroxine, estrogen or progesterone replacement, or 
selective estrogen receptor modulators) for treatment of concurrent medical conditions should 
remain constant during the study whenever possible.
If the need for additional concomitant medication arises, the patient may be continued in the 
study on study medication if, in the investigator’s opinion, the addition of the new medication 
does not pose a safety risk. If an additional concomitant medication is started, the sponsor 
should be informed as soon as possible. Nausea and/or vomiting during this study may be 
treated with antiemetics but should not be used prophylactically.  Nonsteroidal anti-inflammatory 
medications (including ibuprofen, aspirin), acetaminophen, cough suppressants, antihistamines, 
vitamin/mineral supplements, antibiotics, and topical ointments may be used on an as-needed 
basis without notifying the sponsor and are not restricted by the stable dosing requirements listed
above. Any additional medication used during the course of the study (including those not 
requiring sponsor notifications) must be documented on the appropriate electronic case report 
form (eCRF).
Specifically excluded concomitant medications include the following:

I8F-MC-GPGF Clinical Protocol
Page 37
LY3298176

Chronic use of drugs that directly reduce GI motility including but not limited to 
anticholinergics, antiemetics, and opiates (eg, metoclopramide, phenergan, dicyclomine, 
and morphine)

Chronic use of medications that directly promote motility (eg, bethanechol and cisapride)

Prescription or OTC medications to promote weight loss

Systemic glucocorticoid therapy of >14 consecutive days’ duration (with the exception of 
topical, intranasal, intraocular, intra-articular, and inhaled preparations)

Central nervous system stimulants (eg, Ritalin-SR)

Any drug, other than those provided in this study, that has not received regulatory 
approval.
7.8.
Treatment after the End of the Study
7.8.1. Special Treatment Considerations (Rescue Therapy)
Investigators will be trained on how to apply decision criteria for the timing and method of 
intervention in patients who do not reach glycemic targets during the 12-week treatment period.  
An additional therapeutic intervention should be considered in patients who meet the following 
criteria:

The patients are fully compliant with assigned therapeutic regimen.
AND

In the absence of any acute condition that raises blood glucose either of the following 
occurs:
o
During the first 6 weeks post-randomization: An average fasting glucose level 
>270 mg/dL (15.0 mmol/L) occurs over at least a 2-week period (at least 
3 values/week must be available).
OR
o
Any time after the first 6 weeks post-randomization:  An average fasting glucose 
level >240 mg/dL (13.3 mmol/L) occurs over at least a 2-week period (at least 
4 values/week must be available).
If these conditions are met, then patients may begin treatment with another antihyperglycemic 
agent as determined by their physician.  If treatment with another antihyperglycemic agent is 
instituted, then study drug should be permanently discontinued.  Patients may remain in the study 
for safety follow-up, but the date at which they begin rescue therapy will be the last date for 
collection of efficacy measures.

8.
Discontinuation Criteria
8.1.
Discontinuation from Study Treatment
8.1.1. Permanent Discontinuation from Study Treatment

Discontinuation due to a hepatic event or liver test abnormality.  Patients who are 
discontinued from investigational product due to a hepatic event or liver test abnormality 
should have additional hepatic safety data collected via case report form (eCRF).
Discontinuation of the investigational product for abnormal liver tests should be
considered by the investigator when a patient meets one of the following conditions after 
consultation with the Lilly designated medical monitor:  
o
Abnormal liver tests or when a patient meets one of the following conditions:

ALT or aspartate aminotransferase (AST) >8ULN

ALT or AST >5ULN for >2 weeks

ALT or AST >3ULN and total bilirubin level >2ULN or prothrombin 
time >1.5ULN

ALT or AST >3ULN with the appearance of fatigue, nausea, vomiting, 
right upper-quadrant pain or tenderness, fever, rash, and/or eosinophilia 
(>5%)

Alkaline phosphatase (ALP) >3ULN

ALP >2.5ULN and total bilirubin >2x ULN

ALP >2.5ULN with the appearance of fatigue, nausea, vomiting, right 
quadrant pain or tenderness, fever, rash, and/or eosinophilia (>5%).

Investigator decision
o
The investigator decides that the patient should be discontinued from the study 
medication.

Any medication for weight loss is given for >1 week.

Adverse event.

When any one of the following events occur, Lilly or its designee is to be alerted 
immediately:
o
Pancreatitis or pancreatic cancer (refer to Section 9.2.1.2.5 for details)
o
eGFR <30 mL/min/1.73 m2
o
Any severe injection site reaction or ≥2 moderate injection site reactions 
occurring a week or more apart
o
Any study drug-related hypersensitivity reaction
o
Any nonfatal major CV events (refer to Section 9.2.1.2.6 for details)
o
Any other treatment-emergent adverse event (TEAE), serious adverse event 
(SAE), or clinically significant laboratory value for which the investigator 
believes that permanent study drug discontinuation is the appropriate measure to 
be taken.

I8F-MC-GPGF Clinical Protocol
Page 39
LY3298176

If the patient, for any reason (including protocol-mandated institution of rescue therapy; 
see Section 7.8.1), requires treatment for >1 week with another therapeutic agent that has 
been demonstrated to be effective for treatment of diabetes.  Also, a change in dose of 
metformin is not allowed (except for incidences of hypoglycemia; see Section 7.1).  
However, a change to an equivalent dose strength from immediate-release to 
extended-release (or vice versa) formulation is allowed.

If the patient misses 2 doses (consecutive or not) of study medication or intentionally or 
repeatedly takes more than the prescribed dose of study medication (see Section 9.3).

If the patient develops any exclusion criteria, such as pregnancy or nursing.
If study drug is permanently discontinued, the patient should remain in the study if possible.
Patients discontinuing from the investigational product prematurely for any reason should 
complete adverse event and other follow-up procedures per Section 2 (Schedule of Activities), 
Section 9.2 (Adverse Events), and Section 9.4 (Safety) of this protocol.
8.1.2. Temporary Discontinuation from Study Treatment
After randomization, the investigator may temporarily discontinue study drug, for example, due 
to an AE (eg, nausea and vomiting), or a clinically significant laboratory value.  If study drug 
discontinuation is due to an AE, the event is to be followed and documented.  Every effort 
should be made by the investigator to maintain patients in the study and to restart study drug 
promptly after any temporary discontinuation, as soon as it is safe to do so.  The dates of study 
drug discontinuation and restart will be documented.  Patient noncompliance should not be 
recorded as temporary discontinuation of study drug on the eCRF.  If ≥2 doses of study 
medication (consecutive or not) are missed for any reason, then the patient should be 
permanently discontinued from study medication.
In the event that the patient requires the discontinuation of the study drug, he/she may continue 
participation in the study, attend all visits, and undergo all protocol procedures, and patient data 
from the time of discontinuation of study drug will not be included in the primary analyses.
After study drug discontinuation, patients may commence any standard diabetes therapy in line 
with local or regional standards of care, and as considered appropriate by the investigator.
8.1.3. Discontinuation of Inadvertently Enrolled Patients
If the sponsor or investigator identify a patient who did not meet enrollment criteria and was 
inadvertently enrolled, then the patient should be discontinued from study treatment unless there 
are extenuating circumstances that make it medically necessary for the patient to continue on 
study treatment.  If the investigator and the sponsor CRP/CRS agree it is medically appropriate 
to continue, the investigator must obtain documented approval from the sponsor CRP/CRS to 
allow the inadvertently enrolled patient to continue in the study with or without treatment with 
investigational product. Safety follow up is as outlined in Section 2 (Schedule of Activities), 
Section 9.2 (Adverse Events), and Section 9.4 (Safety) of the protocol.

Discontinuation from the Study
Some possible reasons that may lead to permanent discontinuation include the following:

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

Sponsor decision
o
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 patient should be discontinued from the study.

Subject decision
o
The patient requests to be withdrawn from the study.
Patients discontinuing from the study prematurely for any reason should complete adverse event 
and other safety follow-up per Section 2 (Schedule of Activities), Section 9.2 (Adverse Events), 
and Section 9.4 (Safety) of this protocol.
8.3.
Lost to Follow-Up
A patient will be considered lost to follow-up if he/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 patients who fail to return for a scheduled visit or were otherwise 
unable to be followed up by the site.
Site personnel, or an independent third party, will attempt to collect the vital status of the patient 
within legal and ethical boundaries for all patients randomized, including those who did not get 
investigational product.  Public sources may be searched for vital status information.  If vital 
status is determined, this will be documented and the patient will not be considered lost to 
follow-up.
Lilly personnel will not be involved in any attempts to collect vital status information.

9. Study Assessments and Procedures
Section 2 lists the Schedule of Activities, with the study procedures and their timing (including 
tolerance limits for timing).
Appendix 2 lists the laboratory tests that will be performed for this study.
Unless otherwise stated in the 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
9.1.1. Primary Efficacy Assessments
The primary efficacy measure is HbA1c, as determined by the central laboratory.  Blood samples 
for HbA1c measurements will be collected at specific clinical visits as summarized in Section 2. 
9.1.2. Secondary Efficacy Assessments
The following secondary efficacy measures will be collected at the times shown in Section 2.

HbA1c target of <7.0% 

Body weight: Patients will be weighed on an electronic (digital) scale in a light hospital 
gown at approximately the same time in the morning after an overnight fast and 
evacuation of any bowel and bladder contents (see Appendix 7).  The scale’s 
performance will be monitored at least monthly using standard weights, and records of 
these assessments will be kept in the study binder.

FBG 

Waist circumference:  Waist circumference should be measured at the midpoint between 
the lower margin of the least palpable rib and the top of the iliac crest.  The patient
should stand with feet close together, arms at the side, and body weight evenly 
distributed, and should wear a hospital gown. The patient should be relaxed, and the 
measurements should be taken at the end of a normal expiration.  The measurement 
should be repeated.  If the difference between the 2 measurements exceeds 1 cm, the 
2 measurements should be repeated.
9.1.2.1.
Exploratory Efficacy Assessments
Seven-point SMBG profiles consisting of blood glucose measurements should be obtained 
before each meal, approximately 2 hours after each meal, and at bedtime on a day during the 
week before the relevant scheduled clinic visit.  Patients will record their SMBG levels in their 
diaries, according to instructions.  The complete 7-point profile must be collected on a single 
day.  If a patient does not complete the entire profile on a single day, all 7 points must be 
collected on a subsequent day.

I8F-MC-GPGF Clinical Protocol

9.1.3. Appropriateness of Assessments
All measures are widely used and generally recognized as reliable, accurate, and relevant with 
respect to the management of T2DM.
9.2.
Adverse Events
Investigators are responsible for monitoring the safety of patients 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 patient.
The investigator is responsible for the appropriate medical care of patients 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 investigational 
product or the study, or that caused the patient to discontinue the investigational product before 
completing the study.  The patient 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.
Lack of drug effect is not an AE in clinical studies, because the purpose of the clinical study is to 
establish drug effect.
After the ICF is signed, study site personnel will record via eCRF the occurrence and nature of 
each patient’s preexisting conditions, including clinically significant signs and symptoms of the 
disease under treatment in the study.  In addition, site personnel will record any change in the 
condition(s) and any new conditions as AEs. Investigators should record their assessment of the 
potential relatedness of each AE to protocol procedure or investigational product via eCRF.
The investigator will interpret and document whether or not an AE has a reasonable possibility 
of being related to study treatment, study device, or a study procedure, taking into account the 
disease, 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.
The investigator answers yes/no when making this assessment.
In addition to records of observations made at specific times, unexpected signs and symptoms 
and concomitant medications will be recorded in the clinical trial records throughout the study.
Planned surgeries and nonsurgical interventions should not be reported as AEs unless the 
underlying medical condition has worsened during the course of the study.
If a patient’s investigational product is discontinued as a result of an AE, study site personnel 
must report this to Lilly or its designee via eCRF, clarifying if possible the circumstances leading 
to any dosage modifications or discontinuations of treatment.

I8F-MC-GPGF Clinical Protocol

LY3298176
9.2.1. Serious Adverse Events
An SAE is any AE from this study that results in one of the following outcomes:

Death

Initial or prolonged inpatient hospitalization

A life-threatening experience (ie, immediate risk of dying)

Persistent or significant disability/incapacity

Congenital anomaly/birth defect

Considered significant by the investigator for any other reason.  Important medical events 
that may not be immediately life-threatening or result in death or hospitalization but may 
jeopardize the patient or may require intervention to prevent one of the other outcomes 
listed in the definition above.  Examples of such medical events include allergic 
bronchospasm requiring intensive treatment in an emergency room or at home, blood 
dyscrasias or convulsions that do not result in inpatient hospitalization, or the 
development of drug dependency or drug abuse.

When a condition related to the investigational device 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.
All AEs occurring after signing the ICF are recorded in the eCRF and assessed for serious 
criteria.  The SAE reporting to the sponsor begins after the patient has signed the ICF and has 
received investigational product.  However, if an SAE occurs after signing the ICF, but prior to 
receiving investigational product, the SAE should be reported to the sponsor as per SAE 
reporting requirements and timelines (see Section 9.2) if it is considered reasonably possibly 
related to study procedure.
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 by official notification on study-specific SAE forms.  This 
24-hour notification requirement refers to the initial SAE information and all follow-up SAE 
information.
Pregnancy (during 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.
Investigators are not obligated to actively seek AEs or SAEs in subjects once they have 
discontinued and/or completed the study (the patient 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.
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.  

I8F-MC-GPGF Clinical Protocol
Page 44
LY3298176
United States 21 CFR 312.32 and European Union Clinical Trial Directive 2001/20/EC and the 
associated detailed guidances or national regulatory 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.
9.2.1.2.
Adverse Events of Special Interest
The following adverse events of special interest (AESIs) of varying clinical significance will be 
used to determine the tolerability of LY3298176 over the range of doses selected for this clinical 
trial.  All AESIs should be captured and reported to Lilly on the AE eCRF or on a specific eCRF, 
if applicable (see below).  Any AESI that meets the definition of an SAE (see Section 9.2.1) 
must be reported as an SAE.
When any one of the following events occur, Lilly or its designee must be alerted immediately, 
whether it is assessed as an SAE or not:

Confirmed pancreatitis or pancreatic cancer

Any severe injection site reaction or 2 moderate injection site reactions occurring a 
week or more apart

Any study drug-related hypersensitivity reaction

Any other TEAE, SAE, or clinically significant laboratory value for which the 
investigator believes that permanent study drug discontinuation is the appropriate 
measure to be taken.
9.2.1.2.1. Nausea, Vomiting, and Diarrhea
Nausea, vomiting, and diarrhea events will be recorded on a specific eCRF.  They should not be 
recorded as AEs unless the event meets an SAE criterion.  For each event, assessment of severity, 
duration, and investigator’s opinion of relatedness to study drug and protocol procedure will be 
captured.
9.2.1.2.2. Injection Site Reactions
All injection site reactions, including reports of pain and burning, and information regarding 
their time of day, time relative to injection, size, amount of erythema, induration, and pruritus, as 
well as severity, will be recorded on specific eCRFs.  In addition, if the reaction is clinically 
significant, the site should attempt to contact the sponsor for potential follow-up procedures.  
Injection site reactions do not need to be recorded as AEs unless they meet SAE criteria.
9.2.1.2.3. Hypersensitivity Reactions
All hypersensitivity reactions will be reported by the investigator as either AEs or, if any serious 
criterion is met, as SAEs.  Study drug should be temporarily discontinued for any individual 
suspected of having a severe or serious allergic/hypersensitivity reaction to study drug.  Study 
drug may be restarted if, in the opinion of the investigator, the event was not related to study 
drug and when/if it is safe to do so.  If study drug is permanently discontinued, the patient should 
remain in the study.

I8F-MC-GPGF Clinical Protocol
Page 45
LY3298176
9.2.1.2.4. Hypoglycemia
Hypoglycemia episodes will be recorded on a specific eCRF. Information regarding severity, 
time of day, and investigator’s opinion of relatedness to study drug and procedure will be 
recorded.  Hypoglycemia episodes should not be recorded as AEs unless the event meets serious 
criteria.  Hypoglycemia will be classified as follows (American Diabetes Association 2005):

Documented Symptomatic Hypoglycemia:  Any time a patient feels that he/she is 
experiencing symptoms and/or signs associated with hypoglycemia and has a plasma 
glucose level of 3.9 mmol/L (70 mg/dL).

Asymptomatic Hypoglycemia: An event not accompanied by typical symptoms of 
hypoglycemia, but with 3.9 mmol/L (70 mg/dL) plasma glucose.

Severe Hypoglycemia: An episode requiring the assistance of another person to actively 
administer carbohydrate, glucagon, or other resuscitative actions.  These episodes may be 
associated with sufficient neuroglycopenia to induce seizure or coma.  Plasma glucose 
measurements may not be available during such an event, but neurological recovery 
attributable to the restoration of plasma glucose to normal is considered sufficient 
evidence that the event was induced by a low plasma glucose concentration.

Nocturnal Hypoglycemia:  Any hypoglycemic event that occurs between bedtime and 
waking.

Probable Symptomatic Hypoglycemia: An event during which symptoms of 
hypoglycemia are not accompanied by a plasma glucose determination (but that was 
presumably caused by a plasma glucose concentration 3.9 mmol/L [70 mg/dL]).
9.2.1.2.5. Acute Pancreatitis
Acute pancreatitis is defined as an AE of interest for this study. Acute pancreatitis is an acute 
inflammatory process of the pancreas that may also involve peripancreatic tissues and/or remote 
organ systems (Banks et al. 2006). The diagnosis of acute pancreatitis requires 2 of the 
following 3 features:

abdominal pain, characteristic of acute pancreatitis (generally located in the epigastrium 
and radiates to the back in approximately half the cases [Banks et al. 2006; Koizumi et al. 
2006]; the pain is often associated with nausea and vomiting);

serum amylase (total and/or pancreatic) and/or lipase 3ULN;

characteristic findings of acute pancreatitis on computed tomography (CT) scan or 
magnetic resonance imaging (MRI).
If acute pancreatitis is suspected, appropriate laboratory tests (including levels of pancreatic 
amylase and lipase) should be obtained via the central laboratory (and locally, if needed). 
Imaging studies, such as abdominal CT scan with or without contrast, MRI, or gallbladder 
ultrasound, should be performed.  If laboratory values and/or abdominal imaging support the 
diagnosis of acute pancreatitis, the patient must discontinue therapy with investigational product,
but will continue in the study on another glucose-lowering regimen (see Section 7.8.1 for details 
on rescue intervention).  The most appropriate diabetes therapeutic regimen will be decided by 
the investigator, based on the patient’s clinical status.  A review of the patient’s concomitant 
medications should be conducted to assess any potential causal relationship with pancreatitis.

I8F-MC-GPGF Clinical Protocol
Page 46
LY3298176
Each case of AE of pancreatitis must be reported. If typical signs and/or symptoms of 
pancreatitis are present and confirmed by laboratory values (lipase or amylase [total and/or 
pancreatic]) and imaging studies, the event must be reported as an SAE. For a potential case that 
does not meet all of these criteria, it is up to the investigator to determine the seriousness of the 
case (AE or SAE) and the relatedness of the event to study drug.
In addition to the diagnostic assessment in patients who develop symptoms of acute pancreatitis, 
each patient will have measurements of pancreatic amylase and lipase at screening, baseline, and 
during the study, including follow up, to assess any potential effects of LY3298176 on the 
exocrine pancreas (refer to Section 2, Schedule of Activities).  Further diagnostic assessment per 
Lilly algorithm for assessment of asymptomatic pancreatic hyperenzymemia will be required 
whenever lipase and/or pancreatic amylase are 3ULN at any time during the study.  If this 
situation occurs at Visit 801 (Week 15), the patient will be required to undergo this additional 
workup, and the data will be collected in the clinical trial database.
All suspected cases of acute or chronic pancreatitis, as well as cases of confirmed lipase or 
pancreatic amylase values 3ULN, will be adjudicated by an independent committee of expert 
physicians. In addition, AEs of severe or serious abdominal pain of unknown etiology will also 
be submitted to the adjudication committee to assess for possible pancreatitis or other pancreatic 
disease. Relevant data from patients with acute or chronic pancreatitis, those with severe or 
serious abdominal pain, and those that undergo additional assessments due to confirmed 
hyperenzymemia will be entered into a specifically designed eCRF page by study site or Lilly 
staff. The adjudication committee representative will enter the results of adjudication in a 
corresponding eCRF page.
9.2.1.2.6. Major Adverse Cardiovascular Events
Deaths (CV and non-CV), nonfatal MIs, supraventricular arrhythmias, and nonfatal strokes that 
occur during the treatment period or follow-up period will be adjudicated by an independent 
adjudication committee in compliance with a study-specific adjudication charter.  Investigative 
sites will also be asked to submit any cases of TIA or hospitalization for unstable angina for 
adjudication as well to ensure that all true stroke and MI events are captured.  Hospitalizations 
for heart failure and coronary interventions (such as coronary artery bypass graft or percutaneous 
coronary intervention) will also be submitted for adjudication.
Cardiovascular event definitions will be based on the Standardized Definitions for 
Cardiovascular and Stroke Endpoint Events in Clinical Trials (Hicks et al. 2015) and the 
ESC/ACCF/AHA/WHF Expert Consensus Document Third Universal Definition of Myocardial 
Infarction (Thygesen et al. 2012).  An adjudication committee will enter the results of 
adjudication in the corresponding eCRF page.
9.2.1.2.7. Thyroid C-Cell Hyperplasia and C-Cell Neoplasms
Individuals with personal or family history of certain thyroid or nonthyroid endocrine 
abnormalities or certain preexisting laboratory and genetic characteristics will be excluded from 
the study (see Section 6.2).  The assessment of thyroid safety during the trial will include 
reporting of thyroid TEAEs and measurements of calcitonin according to Section 2 at screening

I8F-MC-GPGF Clinical Protocol
Page 47
LY3298176
and Visit 10 (end of treatment) or ET visit.  The purpose of calcitonin measurements is to assess 
the potential of LY3298176 to affect thyroid C-cell function, which includes development of 
C-cell hyperplasia and neoplasms.
Patients who develop serum calcitonin increases 50% of the mean of the screening values AND 
an absolute value 20 pg/mL and <35 pg/mL at Visit 10 (end of treatment) or at ET will be 
asked to repeat the measurement within 1 month.  If this repeat value is increasing (10% 
increase), the patient will be encouraged to undergo additional endocrine assessment and longer
term follow-up by an endocrinologist to exclude a serious adverse effect on the gland.
For patients who require additional endocrine assessment because of increased calcitonin 
concentration per criteria provided in this section, data from the follow-up assessment will be 
collected in the specific section of the eCRF.
9.2.2. Complaint Handling
Lilly collects product complaints on investigational products and drug delivery systems used in 
clinical studies in order to ensure the safety of study participants, monitor quality, and to 
facilitate process and product improvements.
Patients will be instructed to contact the investigator as soon as possible if he/she has a complaint 
or problem with the investigational product or drug delivery system so that the situation can be 
assessed.
9.3.
Treatment of Overdose
For patients with suspected or confirmed overdose with LY3298176, there is no specific 
antidote.  The patient should be watched for GI symptoms and hypoglycemia.  Treatment is 
supportive, depending on the patient’s symptoms.
9.4.
Safety
9.4.1. Electrocardiograms
For each patient, 12-lead ECGs should be collected according to Section 2. Patients must be 
supine for approximately 5 to 10 minutes before ECG collection and remain supine, but awake, 
during ECG collection.
Electrocardiograms should be recorded in triplicate using standardized equipment provided by 
the sponsor.
Consecutive replicate ECGs will be obtained at approximately 1-minute intervals.  
Electrocardiograms may be obtained at additional times, when deemed clinically necessary.  
Collection of more ECGs than expected at a particular time point is allowed when needed to 
ensure high-quality records.
Electrocardiograms will initially be interpreted by a qualified physician (the investigator or 
qualified designee) at the site as soon after the time of ECG collection as possible, and ideally 
while the patient is still present, to determine whether the subject meets entry criteria and for 

I8F-MC-GPGF Clinical Protocol
Page 48
LY3298176
immediate subject management, should any clinically relevant findings be identified.  Any 
clinically significant findings from ECGs that result in a diagnosis and that occur after the patient 
receives the first dose of the investigational treatment should be reported to Lilly or its designee 
as an AE.  The investigator (or qualified designee) is responsible for determining if any change 
in patient management is needed, and must document his/her review of the ECG printed at the 
time of evaluation.
After enrollment, if a clinically significant increase in the QT/QTc interval from baseline or 
other clinically significant quantitative or qualitative change from baseline is identified, the 
patient will be assessed by the investigator for symptoms (eg, palpitations, near syncope, and 
syncope) and to determine whether the patient can continue in the study.  The investigator or 
qualified designee is responsible for determining if any change in patient management is needed 
and must document his/her review of the ECG printed at the time of evaluation from at least 1 of 
the replicate ECGs from each time point.
All digital ECGs will be obtained using centrally provided ECG machines and will be 
electronically transmitted to a designated central ECG laboratory.  The central ECG laboratory 
will perform a basic quality control check (eg, demographics and study details) and then store the 
ECGs in a database.  At a future time, the stored ECG data may be overread by a cardiologist at 
the central ECG laboratory for further evaluation of machine-read measurements or to meet 
regulatory requirements.
The machine-read ECG intervals and heart rate may be used for data analysis and report-writing 
purposes, unless a cardiologist overreading of the ECGs is conducted prior to completion of the 
final study report (in which case, the overread data would be used).
In addition, for each patient, a single ECG will be recorded at screening and if the patient 
discontinues from the study prematurely (Section 2) for immediate patient management. These 
ECGs will be stored at the investigation site.
Any treatment-emergent clinically significant ECG finding resulting in a diagnosis should be 
reported as an AE in the eCRF.
9.4.2. Vital Signs
Sitting BP and PR will be measured using standardized equipment provided by the sponsor.
Vital sign measurements should be taken before obtaining an ECG tracing and before collection 
of blood samples for laboratory testing, at visits where required (see Section 2). The participant 
should be required to sit quietly for 5 minutes before vital sign measurements are taken. An 
appropriately sized cuff (cuff bladder encircling at least 80% of the arm) should be used to 
ensure the accuracy of BP measurements.  The arm used for the BP measurement should be 
supported at heart level. At Visit 1 (screening), to determine which arm should be used to collect 
BP and PR throughout the study, BP and PR will be measured once in each arm, and the arm that 
had the higher systolic BP should be used to collect all 3 measurements of both BP and PR at all 
study visits.  For each parameter (PR, systolic BP, and diastolic BP), 3 measurements will be 
taken using the same arm; the recordings should be taken at least 1 minute apart, and each 

I8F-MC-GPGF Clinical Protocol
Page 49
LY3298176
measurement of sitting PR and BP will be recorded in the eCRF.  Any AE related to changes in 
BP and PR should be reported.
9.4.3. Laboratory Tests
For each patient, laboratory tests detailed in Appendix 2 should be conducted according to the 
Schedule of Activities (Section 2).
Any clinically significant findings from laboratory tests that result in a diagnosis and that occur 
after the patient receives the first dose of investigational product should be reported to Lilly or its 
designee as an AE.
9.4.4. Safety Monitoring
Lilly will periodically review evolving aggregate safety data within the study by appropriate 
methods.  In addition, the study team will review safety reports in a blinded fashion according to 
the schedule provided in the Trial-Level Safety Review plan.  Lilly will also review SAEs within 
time frames mandated by company procedures.  The Lilly CRP/CRS will, as appropriate, consult 
with the functionally independent Global Patient Safety therapeutic area physician or clinical 
scientist.
In addition, specific safety measures are included in the protocol to ensure appropriate 
monitoring of pancreatic, thyroid, and liver safety.  Laboratory findings that trigger pancreatic 
and thyroid safety monitoring per Lilly standards are provided in Sections 9.2.1.2.5 and
9.2.1.2.7, respectively.  Details of liver safety monitoring are provided in Section 8.1.1. If a 
study patient experiences elevated ALT 3ULN or elevated total bilirubin 2ULN, clinical 
and laboratory monitoring should be initiated by the investigator.  Details for hepatic monitoring 
depend upon the severity and persistence of observed laboratory test abnormalities.  To ensure 
patient safety and comply with regulatory guidance, the investigator is to consult with the Lilly 
CRP/CRS regarding collection of specific recommended clinical information and follow-up 
laboratory tests (see Appendix 4).
9.5.
Pharmacokinetics
Blood samples for PK analyses will be collected from all randomized patients in accordance with 
the Schedule of Activities (Section 2) and at ET.  However, only samples from patients assigned 
to treatment with LY3298176 will be analyzed for drug concentration.
Date and time of each sample and the most recent LY3298176 dose prior to PK blood draw must 
be recorded.  Scheduled PK samples must be collected prior to dose administration at scheduled 
visits.
Drug concentration information that would unblind the study will not be reported to study sites 
or blinded personnel while the study is blinded.
Bioanalytical samples collected to measure study drug concentration will be retained for a 
maximum of 1 year following the last patient visit for the study.

I8F-MC-GPGF Clinical Protocol

9.6.
Pharmacodynamics
Samples to evaluate the PD properties of LY3298176 are included in the secondary efficacy 
measures and not applicable here.
9.7.
Pharmacogenomics
Not applicable.
9.8.
Biomarkers
Collection of samples for other biomarker research is part of this study.  Blood samples will be 
collected as specified in Section 2.
Biomarker research is performed to address questions of relevance to drug disposition, target 
engagement, PD, mechanism of action, variability of patient response (including safety), and 
clinical outcome.  Sample collection is incorporated into clinical studies to enable examination of 
these questions through measurements of biomolecules, including DNA, RNA, proteins, lipids, 
and other cellular elements.
Serum and plasma ethylenediaminetetraacetic acid (EDTA) samples for nonpharmacogenetic 
biomarker research will be collected at the times specified in the Schedule of Activities 
(Section 2) where local regulations allow.
Samples will be used for research on the drug target, disease process, variable response to 
LY3298176, pathways associated with diabetes, mechanism of action of LY3298176, and/or 
research method or in validating diagnostic tools or assay(s) related to diabetes.
Samples will be retained for a maximum of 15 years after the last patient visit for the study, or 
for a shorter period if local regulations and ERBs impose shorter time limits, at a facility selected 
by Lilly.  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 LY3298176 or after LY3298176 becomes commercially available.
9.9.
Health Economics
Not applicable.
9.10. Samples for Immunogenicity Research
Samples from all patients will be tested for antidrug antibodies (ADA) against LY3298176.  A 
blood sample will be collected at specific study visits according to the Schedule of Activities
(Section 2).  All samples for immunogenicity should be taken predose when applicable.  To 
interpret the results of immunogenicity, a PK sample should be collected at the same time point 
as an the immunogenicity sample.  In the event of drug hypersensitivity reactions (immediate or 
nonimmediate), additional samples will be collected as close to the onset of the event as possible, 
at the resolution of the event, and 30 days following the event.  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.

I8F-MC-GPGF Clinical Protocol
Page 51
LY3298176
Immunogenicity will be assessed using a validated ligand-binding assay designed to detect and 
titer ADA in the presence of LY3298176 at a laboratory approved by the sponsor. Confirmed 
positive samples for LY3298176 ADA will be titrated and then evaluated for cross-reactive 
binding to native GIP and GLP-1 using a validated ligand-binding assay. They may also be 
tested for their ability to neutralize the activity of assigned treatment (LY3298176-neutralizing 
antibodies) in separate cell-based neutralizing assays over-expressing the GIP and GLP-1 
receptors.  Antidrug antibody samples that test positive for neutralizing activity against 
LY3298176 and/or for cross-reactive binding to native GIP and GLP-1 may then be further
tested for neutralizing activity against native GLP-1 and GIP using cell-based neutralizing 
assays.  
All patients will have an ADA sample measured at ET or at the follow-up visit (Visit 801) 
approximately 1 month after the last dose of LY3298176.  A risk-based approach will be used to 
monitor patients who have clinically significant treatment-emergent antidrug antibodies (TE-
ADA) at the last visit.  Treatment-emergent ADA are defined as those with a titer 2‑fold 
(1 dilution) greater than the minimum required dilution if no ADA were detected at baseline or 
those with a 4-fold (2 dilutions) increase in titer compared to baseline if ADA were detected at 
baseline. Clinically significant TE-ADA will be defined as any TE-ADA at the follow-up visit 
(Visit 801) with:

A high titer (1280) or an increasing titer from last measured value

An association of TE-ADA with a moderate to severe injection site reaction or 
infusion-related reaction

Cross-reactive and/or neutralizing binding of an ADA with endogenous GLP-1 or GIP.
Patients who have clinically significant TE-ADA should be followed with ADA testing every 
3 months for approximately 1 year or until the ADA titers have returned to baseline ADA titer 
(defined as ADA titer within 2-fold of baseline).  A PK sample may be collected at the follow-up 
immunogenicity assessment(s) if warranted and agreed upon between both the investigator and 
sponsor.
Every attempt should be made to contact patients for the follow-up immunogenicity assessment; 
however, if patients are unwilling or unable to return for the visit, this is not considered a 
protocol violation.
Patients followed for at least 1 year since last dose who have not returned to baseline, as defined 
above, will be assessed for safety concerns and, if no clinical sequelae is recognized by the 
clinical team, no further follow-up will be required.
Patients who have clinical sequelae that are considered potentially related to the presence of 
TE-ADA may also be asked to return for additional follow-up testing.
Samples will be retained for a maximum of 15 years after the last patient visit for the study, or 
for a shorter period if regulations and ERBs impose shorter time limits, at a facility selected by 
Lilly.  The duration allows the sponsor to respond to future regulatory requests related to 
LY3298176.  Any samples remaining after 15 years will be destroyed.

Statistical Considerations
10.1. Sample Size Determination
Approximately 92 patients will be randomized to placebo or 1 of 3 LY3298176 titrations arms 
assuming a 13% dropout rate resulting in approximately 20 completers per arm.
Assuming a standard deviation of 1.1, 20 patients per arm will provide at least 90% power to 
detect a statistically significant difference between LY treatments to placebo with a dose 
response assumption as shown in Table GPGF.4.

10.2. Populations for Analyses
For purposes of analysis, the following populations are defined in Table GPGF.5.
Table GPGF.5.
Definitions of Populations to Be Analyzed in Study GPGF
Population
Description
Enrolled
All participants who sign informed consent.
ITT (intention-to-treat)
All randomized patients.
mITT (modified ITT)
All randomized patients with at least 1 postbaseline measurement according to the 
treatment the patients were assigned.
PP (per-protocol)
All randomized patients who were compliant with study drug and completed the protocol.
Safety
All randomized participants who take at least 1 dose of study treatment.  Participants will 
be included in the treatment group to which they were randomized.  In the event of a 
treatment error, participants will be analyzed according to the treatment they actually 
received.
10.3. Statistical Analyses
10.3.1. General Statistical Considerations
Statistical analysis of this study will be the responsibility of Lilly or its designee.  Any change to 
the statistical methods described in the protocol will require an amendment only if it changes a 
principal feature of the protocol.  Any other change to the statistical analyses and the justification 
for the change will be described in the statistical analysis plan (SAP) and/or clinical study report
(CSR).  Additional exploratory analyses of the data may be performed as deemed appropriate.  
Analyses will be fully detailed in the SAP.
The intention-to-treat (ITT) population is defined as all randomized patients.  Statistical analyses 
(including the primary analysis) will be conducted on the modified ITT (mITT) population.  The 
mITT population is defined as all randomized patients with at least 1 postbaseline measurement 
according to the treatment the patients were assigned.  The per-protocol (PP) population is 
defined as all randomized patients who were compliant with study drug and completed the 

I8F-MC-GPGF Clinical Protocol
Page 53
LY3298176
protocol and is a subset of the mITT population.  The safety population is defined as all 
randomized patients who have received at least 1 dose of study drug.  Safety analyses will be 
performed on the safety population.
Some efficacy measures will also be analyzed on the PP dataset.  The PP analysis will include 
patients who meet the following additional criteria:

Have been appropriately randomized

Have not discontinued from the study for any of the early discontinuation criteria

Have not missed 2 doses during the treatment period

Have not been rescued or taken a concomitant antihyperglycemic medication besides 
metformin for >7 cumulative days during the treatment period.
Patients who have had rescue therapy will be included in the mITT population, but not the PP 
population. The efficacy measures will be censored at the time of rescue for analyses using 
mITT population.
No adjustments for multiplicity will be performed.
All tests of treatment effects will be conducted at a one-sided alpha level of 0.1 and/or one-sided 
90% confidence interval, unless otherwise stated.
The baseline value used for the analyses will be the last scheduled baseline value obtained for 
each patient prior to randomization.
10.3.2. Treatment Group Comparability
10.3.2.1. Patient Disposition
All patients who discontinue 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.  The 
primary reasons for discontinuation will be listed and will be summarized by treatment.  The 
percentage of patients discontinuing from each treatment will be compared using the Fisher’s 
exact test.
10.3.2.2. Patient Characteristics
Demographic and baseline characteristics will be summarized by treatment group.  Categorical 
variables will be summarized by frequencies and percentages.  For categorical variables, 
comparisons between treatment groups will be assessed using a Pearson Chi-Square test.  
Continuous variables will be summarized by means and SDs.  For continuous variables, 
comparisons between the treatment groups will be performed using a 1-way analysis of variance 
with treatment as the fixed effect.
10.3.2.3. Concomitant Therapy
Listings and summary of concomitant therapies will be provided by treatment group.
10.3.2.4. Treatment Compliance
Treatment compliance will be listed using all randomized patients and summarized using the 
mITT population.  For a given patient, overall compliance for treatment period is defined as not 

I8F-MC-GPGF Clinical Protocol
Page 54
LY3298176
missing 2 doses of the assigned treatment at any point in the study.  Patients who miss 2 doses 
at any point during the study will be considered significantly noncompliant and will be 
permanently discontinued from study medication.  These patients will not be included in the PP 
analysis.
10.3.3. Efficacy Analyses
10.3.3.1. Primary Analyses
The primary outcome is the difference in HbA1c change from baseline between treatment groups 
based on the mITT population at the planned end of the treatment period of 3 months.  The 
primary analysis model will be a mixed model for repeated measures (MMRM) for HbA1c 
change from baseline to 3 months in the mITT population with treatment, visit, treatment-by-
visit,  baseline BMI category, and metformin use (yes, no) as fixed effects, and baseline HbA1c 
as a covariate. The dependent variable will be the postbaseline change from baseline values.  An 
unstructured covariance structure will be used to model the within-patient errors. If this model 
fails to converge, the following covariance structures will be tested in order:

toeplitz with heterogeneity

autoregressive with heterogeneity, by visit

compound symmetry with heterogeneous variances by visit 

toeplitz

autoregressive

compound symmetry without heterogeneous variances, by visit

compound symmetry.
The first covariance structure that converges will be used.
The treatment p-value will be used as evidence of difference between active drug and placebo, 
while the comparison of least-squares (LS) means versus placebo (unadjusted for multiple 
comparisons) will provide magnitude and significance of this difference. The primary analysis 
model, MMRM, will be repeated using the PP population.  If the conclusion differs from that of 
the mITT population, the data and analyses will be further investigated.  
Descriptive statistics by treatment for HbA1c and HbA1c change from baseline at the 12-week 
endpoint will be presented using all observed data with no imputations and no elimination of 
patients with protocol violations.  The descriptive statistics will be presented by visit and will 
include sample size, mean, SD, median, minimum, and maximum.
10.3.3.2. Secondary Analyses
10.3.3.2.1.Analyses on Secondary Efficacy Endpoints
In addition to the primary efficacy analysis of HbA1c, the following secondary efficacy 
outcomes will be analyzed on the mITT population:

Body weight change from baseline to 3 months

Percentage of patients reaching the HbA1c target of 7.0%

Change from baseline of FBG at 3 months

I8F-MC-GPGF Clinical Protocol
Page 55
LY3298176

Change from baseline of waist circumference at 3 months.
The secondary continuous efficacy measures (change from baseline in body weight, waist 
circumference, and FBG) will also be analyzed using the MMRM models described above (with 
censoring data collected after initiation of rescue intervention).  The MMRM model will include 
the model terms given for the previously described primary analysis model except the baseline of 
the corresponding variable replacing the baseline of HbA1c, and with the addition of the HbA1c 
strata (<8.5% or ≥8.5%). Baseline BMI category will be dropped from the analysis models for 
body weight change from baseline.
The percentage of patients reaching the HbA1c target of 7.0% at 3 months will be analyzed 
using a logistic regression analysis with fixed effects of treatment and stratification factors, and 
baseline as a covariate.
In addition to change from baseline in weight and waist circumference, change from baseline in 
BMI will be listed and summarized.
Descriptive statistics for each outcome will be presented by treatment group.  For continuous 
variables, the descriptive statistics will include sample size, LS means, LS means standard error, 
mean, SD, median, minimum, and maximum.  For categorical variables, the descriptive statistics 
will include sample size, frequency, and percentage.
10.3.3.3. Exploratory Analyses
The change from baseline of 7-point SMBG profiles will be analyzed using analysis of 
covariance model (ANCOVA) with treatment, baseline strata (metformin category, BMI 
category, and HbA1C category) as fixed effects, and the corresponding baseline as covariate.  
10.3.4. Safety Analyses
10.3.4.1. Clinical Evaluation of Safety
The safety population will be used for safety analyses.  
Safety measures will include vital signs, body weight, TEAEs (including SAEs and AESIs), and 
laboratory measures (including anti-LY3298176 antibodies).  Summary statistics will be 
presented by treatment for the safety measures.
The summary statistics for continuous variables will be sample size, mean, SD, median, 
minimum, and maximum.
The summary statistics for categorical variables will be sample size, frequency, and percentage.
Exposure to each therapy during the treatment period of the study will be calculated for each 
patient and summarized by treatment group.
In addition, percent of patients requiring rescue therapy will be summarized.
Additional analysis, such as concentration–safety lab plots, may be performed if warranted upon 
review of the data.

I8F-MC-GPGF Clinical Protocol

LY3298176
10.3.4.2. Adverse Events
Adverse events will be listed by patient, actual term, preferred term, severity, and relationship to 
the treatment.  Adverse events will be summarized as TEAEs (defined as events that are newly 
reported after randomization or reported to worsen in severity from baseline).  The incidence of 
patients with at least 1 TEAE and the incidence of TEAEs by preferred term and system organ 
class will be presented by treatment group.  The frequency and percentage of TEAEs will be 
presented.  The incidence of patients with at least 1 TEAE assessed as possibly related to the 
investigational drug will be summarized by treatment group, in addition to the incidence of these 
possibly related TEAEs by preferred term.  In addition, a summary of TEAEs by severity will be 
presented descriptively by treatment group.
Reported thyroid and adjudicated CV and pancreatic-related AEs will be listed by patient, and if 
there are a sufficient number of cases, they may be summarized by treatment group.
All SAEs will be listed by patient.  If a sufficient number of SAEs are reported, incidence 
summaries similar to incidence of TEAEs will be included.
Discontinuations due to TEAEs will be listed by patient and summarized by treatment group.
10.3.4.3. Vital Signs
All vital signs will be listed using all randomized patients.
Descriptive statistics for the actual measurements and changes from baseline for systolic and 
diastolic BP and PR will be presented by treatment arm and visit.  Corresponding figures may be 
presented.
Vital signs will be analyzed using a similar MMRM-based model as for the primary analysis.
10.3.4.4. Laboratory Measures
Summary statistics will be provided for laboratory measures, by visit.
A listing of laboratory measurements for individual patients will be presented by visit.  An 
additional listing will be presented for all laboratory measurements that are outside the normal 
range.
Descriptive statistics for the laboratory analyses will be presented by treatment group and visit, 
including safety off-treatment visits.
Laboratory analyses with categorical responses will be summarized by visit and treatment group 
using frequency and percentage.
Shift tables will be evaluated at endpoint (last observation carried forward [LOCF]); the 
maximum/minimum postbaseline observation (as applicable for a lab) will be compared to the 
baseline observation by examining the proportion of patients whose test values are within and 
outside the reference ranges.
10.3.4.5. Evaluation of Immunogenicity
The frequency of antibody formation (including titers) to LY3298176 will be determined.  If a
cross-reactivity or neutralization assay is performed, the frequency of antibodies will be 

I8F-MC-GPGF Clinical Protocol
Page 57
LY3298176
determined.  If there are a sufficient number of patients with positive antibodies to LY3298176, 
the change of antibodies (negative to positive) will be summarized using shift tables.
The relationship between the presence of antibodies, antibody titers, and clinical parameters (eg, 
AEs, efficacy measures) may be assessed.  Likewise, the relationship between antibody titers, the 
PK parameters, and PD response to LY3298176 may be assessed.
10.3.4.6. Adverse Events of Special Interest
Hypoglycemia, hypersensitivity reactions, injection site reactions, acute pancreatitis, major 
adverse CV events, and selected GI events such as nausea, vomiting, and diarrhea, are defined as 
AESIs.
Descriptive statistics for the AESIs will be presented by treatment group and visit.  Continuous 
responses will be summarized using sample size, mean, SD, median, minimum, and maximum, 
whereas categorical responses will be summarized using frequencies and percentages.
Summaries and analyses for incidence, time to onset, duration, and severity of GI events (nausea, 
vomiting, and diarrhea) will be provided for each treatment group during the 12-week treatment 
period and by visit. The planned reports will be detailed in the statistical analysis plan.
Additional analyses will be performed if necessary.
10.3.4.7. Hypoglycemic Episodes
Hypoglycemic episodes will be defined as follows:  documented symptomatic hypoglycemia, 
asymptomatic hypoglycemia, probable symptomatic hypoglycemia,  nocturnal hypoglycemia,
and severe hypoglycemia.  Total or overall hypoglycemia is defined as any event meeting the 
criteria for documented symptomatic hypoglycemia, asymptomatic hypoglycemia, or probable 
symptomatic hypoglycemia.
The total hypoglycemia monthly rate per patient will be summarized where 1 month is defined as 
a 30-day period.  This will be calculated by dividing the total number of hypoglycemic events by 
the total number of days between visits and multiplying by 30 days.  This rate will also be 
calculated per patient for nocturnal hypoglycemia episodes, and summarized by treatment.
The incidence and rate of total hypoglycemic episodes and nocturnal hypoglycemic episodes will 
be presented for each visit (incidence between visits) and overall.  Nocturnal hypoglycemia 
episodes are episodes that occur between bedtime and waking.  The incidence of hypoglycemic 
episodes during a time period on treatment is defined as patients with at least 1 hypoglycemic 
episode occurring within that period of time.  
Listings of hypoglycemic episodes and severe hypoglycemic episodes will be presented by visit 
for each patient.  If a sufficient number of severe hypoglycemic episodes are reported, then 
incidence summaries similar to incidence of hypoglycemic episodes will be included.
10.3.5. Pharmacokinetic/Pharmacodynamic Analyses
LY3298176 trough PK samples collected over the course of this study will be used to assess that 
exposures in the study are consistent with known LY3298176 PK. 

I8F-MC-GPGF Clinical Protocol
Page 58
LY3298176
Additionally, PK/PD data from this study may be used as a validation dataset to enable 
evaluation of PK/PD models built based on data from the core Phase 2 study GPGB.  These 
analyses may be conducted using nonlinear mixed-effects modeling implemented with the 
NONMEM software.
If antidrug antibody titers are detected from immunogenicity testing, then the impact of 
immunogenicity titers on LY3298176 PK or any relevant PD parameters may also be examined.
10.3.6. Other Analyses
10.3.6.1. Subgroup Analyses
Subgroup analyses of important factors, including age, race, ethnicity, gender, duration of 
diabetes, baseline HbA1c (<8.5%, 8.5%), metformin use (Yes/No) at baseline, BMI, and other 
factors to be specified in the SAP are planned for the key outcomes of HbA1c.
These will be conducted using the ANCOVA model with strata, treatment, factor, 
treatment-by-factor interaction as fixed effects, and baseline as covariate.
Other exploratory subgroup analyses may be performed as deemed appropriate.
10.3.6.2. Interim Analyses
No interim analyses are planned for this study.  If an unplanned interim analysis is deemed 
necessary, the appropriate Lilly medical director, or designee, will be consulted to determine 
whether it is necessary to amend the protocol.

Criteria for Diagnosing Type 2 Diabetes 
Appendix 5.
Mellitus (American Diabetes Association 2017)
Criteria for Diabetes Diagnosis:  4 Options

Fasting blood glucose (FBG) ≥126 mg/dL (7.0 mmol/L)
Fasting is defined as no caloric intake for at least 8 hours.*

2-hr plasma glucose (PG) ≥200 mg/dL (11.1 mmol/L) during oral glucose tolerance test 
(OGTT)
The test should be performed as described by the World Health Organization (WHO), 
using a glucose load containing the equivalent of 75 g anhydrous glucose dissolved in 
water.*

A1c ≥6.5% (48 mmol/mol)
The test should be performed in a laboratory using a method that is National 
Glycohemoglobin Standardization Program (NGSP)-certified and standardized to the 
Diabetes Control and Complications Trial (DCCT) assay.*

In a patient with classic symptoms of hyperglycemia or hyperglycemic crisis, a random 
PG ≥200 mg/dL (11.1 mmol/L).
* In the absence of unequivocal hyperglycemia, results should be confirmed by repeat testing.

Contraceptive Methods
Appendix 6.
Men
Male patients with female partners of child-bearing potential will be required to use a condom in 
conjunction with a spermicidal gel, foam, cream, or suppository.  In addition, the female partner, 
will be requested to use an additional effective form of contraception, which can be any of the 
following:

diaphragm with spermicide

cervical sponge

cervical cap with spermicide

combined oral contraceptive pill and mini-pill

NuvaRing

implantable contraceptives

injectable contraceptives (such as Depo-Provera)

intrauterine device (such as Mirenaand ParaGard)

true abstinence, when in line with the preferred and usual lifestyle of the patient.
Men who have had a vasectomy with appropriate postvasectomy documentation of the absence 
of sperm in the ejaculate are not required to use contraception.  In addition, Inclusion 
Criterion 3b (Section 6.1) provides a specific definition of women not of child-bearing potential; 
these subjects will not be required to use contraception.  Male patients with a female partner 
meeting the definition of a woman not of child-bearing potential will not be required to use 
contraception.
Women of Child Bearing Potential
Women of child-bearing potential will be required to use contraception, which can be any of the 
following:

Abstinence: 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.

Birth Control:  Use of 1 highly effective method (<1% failure rate) of contraception, or a 
combination of 2 effective methods of contraception for the entirety of the study:
o
Either 1 highly effective method of contraception (such as combination oral 
contraceptives, implanted contraceptives, or intrauterine device) 
o
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. 

I8F-MC-GPGF Clinical Protocol
Page 75
LY3298176
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.

World Health Organization Standardized 
Appendix 7.
Protocols for the Measurement of Height and Weight
The following information has been adapted from standardized physical measurement protocols 
for the World Health Organization’s STEPwise approach to Surveillance (STEPS) (WHO 2017).
Measuring Height
Step 1.  Ask the patient to remove their footwear and any headgear (light headgear worn for 
religious reasons can remain, but this should be worn by the patient at every clinic visit when 
their weight is measured).
Step 2.  Ask the patient to stand on the calibrated height measuring board (stadiometer) or 
against a wall with their feet together and their knees straight with their heels against the back 
board or the stadiometer or the wall.
Step 3.  Ask the patient to look straight ahead without tilting their head up.
Step 4.  Ask the patient to breathe in and stand tall. If using a stadiometer or fixed measuring 
device, move the device’s measurement arm gently down onto the top of the patient’s head. 
Record the patient’s height in centimeters (cm).
Measuring Weight
Body weight measurements should be done in a consistent manner using a calibrated scale 
(digital). All weights for a given patient should be measured using the same scale, whenever 
possible, after the patient has emptied their bladder. Patients should wear a light hospital gown 
while their weight is measured.
Step 1. Ask the patient to remove their outer clothing and footwear (underwear may remain on), 
and change into a light hospital gown.
Step 2. Make sure the scale is placed on a firm, flat, even surface (not on carpet or on a sloping 
surface or a rough uneven surface).
Step 3. Ask the patient to step onto the scale with one foot on each side of the scale.
Step 4. Ask the patient to stand still with their arms by their sides and then record their weight in 
kilograms (kg).
