2. Synopsis
Study Rationale
This prospective, randomized clinical trial will provide clinical information on the use of human 
regular U-500 insulin (Humulin® R U-500; U-500R) in high-dose insulin-requiring patients with 
type 2 diabetes mellitus (T2DM).  Gaps in scientific and clinical knowledge for U-500R include 
initial dosing and transition from high-dose U-100 insulin therapy, dose titration including use of 
multiple daily injections (MDI) delivered three times daily (TID), administration safety in 
combination with antihyperglycemic agents (AHAs), and transition from U-500R MDI to 
continuous subcutaneous insulin infusion (CSII).  Delivery of U-500R by CSII is used in patient 
care in United States (US) clinical practice (Reutrakul et al. 2011; Lane et al. 2013; Eby et al. 
2014), but this mode of administration is not approved by the US Food and Drug Administration 
(FDA).  A prospective, randomized clinical trial is needed to evaluate the efficacy and safety of 
U-500R delivered by CSII as compared to U-500R by MDI delivered TID, using a novel version 
of the OmniPod® Insulin Management System that is intended to deliver U-500 insulin with 
dosage in insulin units (U) without converting to U-100 “pump units” (Lane et al. 2009; Segal et 
al. 2010; Lane et al. 2010; Cochran et al. 2014), which is what would be required if U-500 
insulin were to be used in a U-100 insulin system.

Title of Study:  Safety and Efficacy of Human Regular U-500 Insulin Administered by Continuous Subcutaneous 
Insulin Infusion versus Multiple Daily Injections in Subjects with Type 2 Diabetes Mellitus: A Randomized, Open-
Label, Parallel Clinical Trial (VIVID:  Evaluating U-500R Infusion versus Injection in Type 2 Diabetes Mellitus)
Number of Planned Subjects: Approximately 320 subjects requiring high dose insulin without use of glucagon-
like peptide-1 (GLP-1) receptor agonists or sodium-glucose transporter protein (SGLT2) inhibitors (Group A) and 
approximately 64 to 96 additional subjects with use of GLP-1 receptor agonists or SGLT2 inhibitors (Group B),
with or without other insulins/AHAs will be randomized based on a 1:1 ratio to two treatment arms.  After Group A 
has been fully enrolled, Lilly may stop enrollment for Group B, even if the minimum recruitment goal for Group B 
has not been met.  Approximately 240 (Group A) and 48 to 72 (Group B) subjects are expected to complete the 26-
week treatment period (assuming a 25% dropout rate).  
Entered: Approximately 586 subjects (450 in Group A plus an additional 90 to 136 in Group B)
Enrolled/Randomized: Approximately 416 subjects (320 in Group A plus an additional 64 to 96 in Group B)
Completed: Approximately 312 subjects (240 in Group A plus an additional 48 to 72 in Group B)
Phase of Development:  3b
Length of Study:  18 months
Estimated first patient visit:  October 2015                           Estimated last patient visit:  December 2016
Objectives:
The primary objective is to demonstrate the change in glycated hemoglobin A1c (HbA1c) of U-500R administered 
by CSII is noninferior to U-500R administered by MDI therapy from baseline to the 26-week in high-dose insulin-
requiring patients with T2DM who have inadequate glycemic control on high-dose non U-500R (>200 and ≤600 
units per day) insulins (CSII or MDI) and/or high-dose U-500R insulin (MDI) without use of GLP-1 receptor 
agonists or SGLT2 inhibitors and with or without other insulins/AHAs. This population is referred to as Group A.
The following hypothesis will be tested for the primary objective: 
H1: CSII is noninferior to MDI in change in HbA1c using a noninferiority margin (NIM) of 0.4%.
The family-wise type I error rate for the primary objective and the following key secondary objectives will be 
controlled at a two-sided 5% level by the graphical approach.
Key Secondary Objectives:
The following 4 key (alternative hypotheses [H#]) secondary objectives at Week 26 are to demonstrate for the main 
study population (Group A [without use of GLP-1 receptor agonists or SGLT2 inhibitors]) that:
H2: CSII is superior to MDI in change in fasting plasma glucose (FPG).
H3: CSII is superior to MDI in proportions of subjects achieving HbA1c targets/values <7.0%.
H4: CSII is superior to MDI in change in HbA1c.
H5: CSII is superior to MDI in proportions of subjects achieving HbA1c targets/values <7.5%.
The following 5 key (alternative hypotheses [H#]) secondary objectives are to demonstrate the objectives at Week 
26 for the total study population (Group A [without use of GLP-1 receptor agonists or SGLT2 inhibitors] and Group 
B [those who use GLP-1 receptor agonists or SGLT2 inhibitors use]) that:
H6: CSII is noninferior to MDI in change in HbA1c using a NIM of 0.4%.
H7: CSII is superior to MDI in change in fasting plasma glucose (FPG).
H8: CSII is superior to MDI in proportions of subjects achieving HbA1c targets/values <7.0%.
H9:  CSII is superior to MDI in change in HbA1c.
H10: CSII is superior to MDI in proportions of subjects achieving HbA1c targets/values <7.5%.

Statistical Methods:  
Approximately 320 subjects requiring high-dose insulin without use of GLP-1 receptor agonists or SGLT2 inhibitors
(Group A) and approximately 64 to 96 additional subjects with use of GLP-1 receptor agonists or SGLT2 inhibitors
(Group B) will be randomized based on a 1:1 ratio to two treatment arms.  Approximately 240 (Group A) and 48 to 
72 (Group B) subjects are expected to complete the 26-week treatment period (assuming a 25% dropout rate).
The sample size was calculated based on the first primary objective for subjects without use of GLP-1 receptor 
agonists or SGLT2 inhibitors (Group A).  The 240 completers will provide 80% statistical power to demonstrate the 
noninferiority (NIM is 0.4%; SD=1.1%) of U-500R insulin CSII versus U-500R MDI in change in HbA1c at 26 
weeks at a 2-sided alpha = 0.05.
Adjustment for Multiplicity:  A graphical approach will be used to adjust multiplicity for the primary and key 
secondary objectives.  This approach will control the family-wise Type 1 error rate at alpha=0.05.

Randomization Details:  Stratify by entry HbA1c ≥8.5% or <8.5%, nonusers versus users of GLP-1 receptor agonists
or SGLT2 inhibitors, and U-500-R at entry versus other insulins.
Safety Committee and Interim Analysis:
Trial level safety reviews (TLSRs) using selected blinded safety data will be conducted throughout the study by the 
study team.  In addition, a DMC (Data Monitoring Committee) will have access to unblinded data for their 
review(s).  Only the DMC is authorized to evaluate unblinded interim safety analyses.  The DMC will be composed 
of individuals internal and external to Lilly who are not part of the study team and will monitor the safety of U-500R
administered CSII or MDI and may recommend changes to the protocol, including termination.  Unblinding details 
are specified in the unblinding plan section of the Statistical Analysis Plan (SAP) and/or DMC Charter.  The timing 
and frequency of these data reviews will be stated in the DMC charter.  In the event of any patient safety concerns, 
the DMC will communicate to the study team so that the clinical research physician/clinical research scientist can 
inform the investigator of appropriate action.  Study sites will receive information about interim results ONLY if 
they need to know for the safety of their subjects. 
If an unplanned interim analysis is deemed necessary, the appropriate Lilly regulatory scientist will be consulted to 
determine whether it is necessary to amend the protocol.
Primary Efficacy: 
The primary efficacy measure is change from baseline (last nonmissing value at or prior to the treatment starting at 
Visit 4) to the 26-week HbA1c value, which will be summarized and analyzed using a mixed-model repeated 
measures (MMRM) approach for the All Randomized Set (ARS) population.  The baseline is selected to be the last 
value on or prior to the treatment starting visit: Visit 4 (Week 0).  Neither last-observation-carried-forward (LOCF) 
method nor other imputation methods will be used for the outcome measures. However, LOCF method will be used 
for sensitivity analysis.  The MMRM model adjusts for missing data through an observed-data-likelihood-based 
approach.  The model will include the following fixed effects:  treatment (U-500R CSII, U-500R MDI), weeks on 
treatment, the interaction between treatment and weeks, and the appropriate stratification factor (nonusers versus 
users of GLP-1 receptor agonists or SGLT2 inhibitors and U-500R at entry versus other insulins).  The model will 
also include baseline HbA1c as a covariate.  An unstructured covariance matrix will be first modeled for the 
repeated measures of each subject.  If the analysis fails to converge, the following variance-covariance matrix will 
be used (in order) until one converges:
1.
Heterogeneous compound symmetry;
2.
Compound symmetry;
3.
First-order autoregressive.
The test for the first primary objective of noninferiority will be performed at the 0.05 significance level using the 
least-squares (LS) mean estimate of the difference in change in HbA1c between the two treatments at Week 26.  
Noninferiority will be established if the upper limit of a 2-sided 95% confidence interval (CI) for the difference 
(U 500R CSII minus U-500R TID) is below the NIM of 0.4%.
Using the LS mean estimate of the difference in change in HbA1c between the 2 treatments, superiority will be 
established if the upper limit of a two-sided 95% CI for the difference (U-500R CSII minus U-500R MDI) is 
below 0.
The following supportive and sensitivity analyses will also be conducted:

If the following sets are different from the ARS, then similar MMRM analyses will be done for the Full 
Analysis Set (subjects who were randomized and received at least 1 dose of the study insulin through the 
administration method they were assigned to), All Completer Set (subjects who complete the study), and the 
Per-Protocol Population (subjects included in the ARS who have completed the study without significant 
protocol violations).

An ‘analysis of covariance’ model with similar fixed effects as in the MMRM analysis using LOCF method 
for the ARS population.
Secondary Efficacy:
Similar MMRM models for the ARS population will be used to analyze the change from baseline for the following 

B5K-MC-IBHD Clinical Protocol

LY041001
values at week 26:
1)
FPG (by laboratory measurement)
2)
7-point SMBG
3)
Total Daily Insulin dose (TDD)
Baseline values will be the last value obtained for each subject at or prior to the randomization visit: Visit 4, unless 
otherwise stated.  The MMRM model will include similar fixed effects as in the primary analysis, with the 
corresponding baseline measures included as a covariate.  The model specifications will be carefully adjusted as 
appropriate.
For the following values at week 26:

Proportions of subjects achieving HbA1c targets/values (≤6.5%; <7.0%; <7.5% and <8.0%). 

Proportions of subjects achieving HbA1c targets/values (≤6.5%; <7.0%; <7.5% and <8.0%) without 
documented symptomatic hypoglycemia (SMBG <50 mg/dL).
Treatment comparisons will be analyzed using a repeated-measure logistic regression model including subject to 
account for the repeated measurements and similar fixed effects as in the above MMRM models.  The proportion of 
subjects achieving HbA1c targets with no documented symptomatic hypoglycemia (from baseline to corresponding 
visit) will be analyzed using a similar repeated-measure logistic regression model including the baseline documented 
symptomatic hypoglycemia event rate as a covariate.
Safety Analyses:
All of the secondary objectives related to safety will be analyzed for Group A and for the total study population 
(Groups A and B combined). All safety measures will be summarized for ARS by treatment and by visit for the 
26-week treatment period. Safety measures will also be listed for those patients who discontinue study treatment but 
still remain in the study for safety monitoring purpose. These listings will contain data after the patients discontinue 
study treatment. For treatment comparisons of frequency and proportion of event variables (such as AEs and 
hypoglycemia events), the conventional Fisher’s exact test or Pearson’s chi-square test are appropriate to use. 
Hypoglycemia:  (documented [documented symptomatic, asymptomatic, and unspecified], severe, and nocturnal
episodes):  The rate per 30 days calculated between 2 visits is defined as the total number of episodes for all subjects 
between the visits divided by the total actual number of exposure days between the visits, and then multiplied by 
30 days.  A similar definition will be used to calculate the rate per subject per 365 days (year).  For documented 
(documented symptomatic, asymptomatic and unspecified), severe, and nocturnal hypoglycemic episodes, the 
following analyses will be conducted.  The incidence and percentage of subjects with at least 1 hypoglycemic event 
will be analyzed using Fisher’s exact test or Pearson’s chi-square test, as appropriate.  The rate of hypoglycemia 
events per 30 days and per 365 days will be analyzed using a repeated-measure negative binomial regression model 
with similar fixed effects as in the primary analysis model.  Baseline hypoglycemia event rate for the corresponding 
category of the dependent hypoglycemia variable will be included as a covariate, as well as the stratification factors.
Body Weight:  The body weight change will be analyzed separately by MMRM models similar to that which will be 
used in the primary analysis for the ARS population.  The model specifications will be adjusted as appropriate.

B5K-MC-IBHD Clinical Protocol

LY041001
TEAEs and serious adverse events (SAEs): Adverse events will be listed by subject, system organ class, preferred 
term, severity, and relationship to the study disease, drug, device, or procedure.  Adverse events will be summarized 
as TEAEs during treatment period (defined as events that are newly reported after randomization Visit 4 or reported 
to be worsened in severity from randomization Visit 4) for ARS by treatment and visit. The frequency and 
proportion of subjects experiencing at least 1 of each reported TEAE will be summarized for treatment period.  The 
frequency and proportion comparisons will be analyzed using Fisher’s exact test or Pearson’s chi-square test, as 
appropriate.  The frequency and proportion of subjects experiencing at least 1 of each reported TEAE that are 
assessed as possibly related to the study disease, drug, device, or procedures will also be summarized. All SAEs 
(including severe hypoglycemic events) will be listed by subject with similar information as the AE listing.  If a 
sufficient number of SAEs are reported, then a frequency and proportion summary, similar to the summary for 
TEAEs, will be included for the ARS.  
Vital Signs:  Systolic and diastolic blood pressures and pulse will be summarized by visit and for endpoints (LOCF).  
Change from baseline to the last visit of each period for actual endpoint and endpoint (LOCF) will be summarized.
Study Treatment Exposure:  Exposure to each treatment will be calculated for each subject and summarized by 
treatment.  Total subject-years will be included in the summaries.
Laboratory Measures (chemistry, hematology, lipids): Treatment-emergent high, low, and abnormal values will be 
summarized for each lab measure.
Further details of analyses will be provided in the SAP.  
Patient Reported Outcome Measures: As an exploratory objective, the TRIM-D and TRIM-DD measures will be 
used to compare the change in diabetes treatment and diabetes treatment device on patient’s functioning, well-being 
and quality-of-life outcomes from baseline to the 26-week values between treatment groups.  These analyses will be 
performed on the ARS using a MMRM model (similar to the primary/secondary analyses).  Summaries of the 
continuous variables will include sample size, mean, SD, median, minimum, maximum, LS mean and standard error 
(SE) of LS mean.

5. Introduction
Although human regular U-500 insulin (Humulin® R U-500; U-500R) has been available in the 
United States (US) market for more than 50 years, its clinical use has increased over the past 
5 years due to the worsening epidemics of type 2 diabetes mellitus (T2DM) and obesity (Lane et 
al. 2009; Segal et al. 2010; Cochran et al. 2014).  
According to published clinical reports and expert clinical reviews, high-dose insulin-treated
insulin-resistant patients (requiring >200 units of U-100 insulin) have been treated successfully 
and safely with U-500R by injection, resulting in improved glycemic control (glycated 
hemoglobin A1c [HbA1c] reductions between 1% and 2%) with uncommon reports of severe 
hypoglycemia (Neal 2005; Ballani et al. 2006; Lane et al. 2009; Nayyar et al. 2010; Dailey et al. 
2010; Quinn et al. 2011; Ziesmer et al. 2012; Boldo and Comi 2012; Reutrakul et al. 2012; Jones 
and Idris 2013; Hood et al. 2015). U-500R is typically dosed utilizing multiple-daily injections 
(MDI) with either twice daily (BID) or three times daily (TID) dosing (Humulin R U-500 
package insert; de la Peña et al. 2011; Reutrakul et al. 2012). One small (N=28) randomized 
controlled trial of U-500R was recently published reporting a significant mean HbA1c reduction
of 1.0% to 1.7% from baseline to 24-week endpoint (p=0.0001) with no reported episodes of 
severe hypoglycemia when combined with metformin and/or exenatide (Distiller et al. 2014).  
The effect of U-500R begins within 30 minutes, has a peak similar to that observed with human 
regular U-100 insulin (U-100R), and has a relatively long duration of activity (up to 24 hours) 
following a single dose as compared with U-100R (de la Peña et al. 2011). Similarly, a U-500R 
pharmacokinetic/pharmacodynamics simulation modeling study indicated the steady-state basal 
pharmacokinetic/pharmacodynamics effect from both BID and TID dosing appears to support 
use of U-500R as insulin monotherapy (de la Peña. 2014). A recently completed randomized, 
controlled Phase 4 trial (B5K-US-IBHC) comparing TID versus BID U-500R monotherapy over 
24 weeks in 325 subjects demonstrated that U-500R as insulin monotherapy is safe and 
efficacious (HbA1c reduction of 1.1% to 1.2% [Hood et al. 2015]). 
Clinical expert reviews recommend MDI delivered TID injections for all dosage ranges of 
U-500R (Cochran et al. 2005; Lane et al. 2009; Segal et al. 2010; Reutrakul et al. 2012; Cochran 
et al. 2014).  A number of clinical case series (Knee et al. 2003; Schwartz 2004; Lane 2006; 
Bulchandani et al. 2007; Lane et al. 2010; and Reutrakul et al. 2011) have also reported use of 
U-500R by continuous subcutaneous insulin infusion (CSII), a practice that may account for 
approximately one quarter of current U-500R therapy according to recent large retrospective 
real-world claims database analysis (Eby et al. 2014).  These U-500 CSII therapy case series 
have shown improvements in HbA1c from 1.2% (Lane et al. 2010) to 3.5% (Knee et al. 2003), 
and a mean reduction of 1.64% in a review by Reutrakul et al. (2012) which reported severe 
hypoglycemia in 2 (n=55) subjects.  The largest and longest case series (N=59; mean duration of 
follow up 49 months [range: 12 to 114 months]; Lane et al. 2013) reported 1.0% mean decrease 
in HbA1c (from 8.3% to 7.3%) sustained over 66 months of U-500 CSII therapy with severe 
hypoglycemia rate (defined by blood glucose [BG] ≤50 mg/dL or “blood glucose requiring 
treatment [regardless of value])”) at 0.1 episodes per patient per year.  

B5K-MC-IBHD Clinical Protocol
Page 21
LY041001
The aforementioned studies with U-500R in CSII therapy lacked controls, were predominately 
retrospective, and included a small number of subjects (60 subjects per study; total: 
114 subjects).  Additionally, delivery by CSII in currently marketed insulin pumps requires dose 
transition to “U-100 insulin pump units” (one-fifth of actual U-500R dose per volume; Lane et 
al. 2006; Lane et al. 2009; Lane et al. 2010; Segal et al. 2010; and Cochran et al. 2014), which 
has the potential to result in dosing confusion and medication errors.
In summary, there is a clear clinical need to study the use of U-500 by CSII in a prospective, 
randomized clinical trial. Thus, Lilly has developed protocol B5K-MC-IBHD to evaluate the
efficacy and safety of U-500R delivered by CSII as compared to U-500R MDI delivered TID.
The CSII system uses a novel insulin pump device that is not commercially available with 
internal software appropriate for U-500 insulin dosage in U-500 insulin units.  
Input obtained from T2DM patient interviews for this protocol development indicates a wide 
spectrum of knowledge and ability to utilize CSII features by patients.  The current trial design 
was developed to meet the needs of high-dose insulin-requiring patients who could benefit from 
improved glycemic control with CSII.  The unique properties of U-500R demonstrate that it can 
be used as both basal and bolus therapy in MDI or CSII regimens (CSII 50% basal and 50% 
bolus) (Hirsch 2010; de la Peña et al. 2011; Hood et al. 2015). The functionality of the OmniPod 
U-500 system in the trial allows for those patients requiring simpler interface, as well as those 
who would benefit from increased individualization.  For example, the CSII treatment arm will 
initially utilize 2 basal rates for simplicity but allow for individualization up to 4 basal rates if 
needed.  Additionally, a variety of bolus options will be available including boluses based on 
carbohydrate (CHO) counting, fixed meal doses, or doses based on meal sizes (small, medium,
or large). 
It is estimated that 10% to 18% of patients treated with U-500R are on concomitant noninsulin 
injectable therapy, including glucagon-like peptide-1 (GLP-1) receptor agonist therapy (Eby et 
al. 2013, 2014 and Data on File).  Although the percentage of U-500R used in combination with 
sodium-glucose co-transporter 2 (SGLT2) inhibitors is unknown, combination of SGLT2 
inhibitors with U-100 insulin has risen by 4-fold to 1.4% (July 2013 to April 2014 [IMS Data on 
File]).  GLP-1 receptor agonists and SGLT2 inhibitors have been used in insulin-sparing and 
weight attenuating strategies and have shown clinical utility in combination with U-500R or 
U-100 insulin (Lane et al. 2011; Rosenstock et al. 2014).  Two study population groups 
(Groups A and B) will be stratified by nonuse or use of these therapies.  Subjects in each group 
will be randomly assigned equally between treatment arms.  Study population Group A will 
include patients who are not using GLP-1 receptor agonists or SGLT2 inhibitors. The study 
population Group B will include patients who are using GLP-1 receptor agonists or SGLT2
inhibitors.  Group A will be the primary analysis population.  Combined Groups A and B will be 
included in the key and other secondary objectives. The use of GLP-1 receptor agonists or
SGLT2 inhibitors is also intended for exploratory analyses.  
Appropriate testing supporting use of the U-500R in the OmniPod U-500 Insulin Management 
System in clinical trials has been completed.  More detailed information about the known and 
expected benefits and risks of U-500R may be found in the U-500R package insert.  More

6. Objectives
6.1.
Primary Objective
The primary objective is to demonstrate the change in HbA1c of U-500R administered by CSII is 
noninferior to U-500R administered by MDI therapy from baseline to the 26-week in high-dose 
insulin-requiring patients with T2DM who have inadequate glycemic control on high-dose non 
U-500R (>200 and ≤600 units per day) insulins (CSII or MDI) and/or high-dose U-500R insulin 
(MDI) without use of GLP-1 receptor agonists or SGLT2 inhibitors and with or without other 
insulins/antihyperglycemic agents (AHAs).  This population is referred to as Group A. 
The following hypothesis will be tested for the primary objective:
H1: CSII is noninferior to MDI in change in HbA1c using a noninferiority margin (NIM)
of 0.4%.
The family-wise type I error rate for the primary objective and the following key secondary 
objectives will be controlled at a two-sided 5% level by the graphical approach, which will be 
discussed in detail in the Statistical Analysis Plan (SAP).

Summary of Study Design
Study B5K-MC-IBHD is a Phase 3b, multicenter, randomized, open-label, parallel clinical trial 
comparing U-500R administered by CSII (OmniPod U-500 system) to U-500R administered
MDI in high-dose insulin-requiring patients with T2DM who have inadequate glycemic control
on high-dose non U-500R (>200 and ≤600 units per day) insulins (CSII or MDI) and/or U-500R 
insulin (MDI) with or without other insulins/AHAs.  The trial design includes: 1-week screening
period, 2-week lead-in period, and a 26-week treatment period (2 week transition to U-500R
MDI administered TID, 12 weeks titration and 12 weeks maintenance U-500R CSII or MDI).  
As shown in the following recruitment plan (Table IBHD.7.1), approximately 320 subjects 
requiring high-dose insulin without use of GLP-1 receptor agonists or SGLT2 inhibitors (Group 
A) and approximately 64 to 96 additional subjects who are using GLP-1 receptor agonists or
SGLT2 inhibitors (Group B) with or without other AHAs will be randomized based on a 1:1 
ratio to two treatment arms.  After Group A has been fully enrolled, Lilly may stop enrollment 
for Group B, even if the minimum recruitment goal for Group B has not been met.  
Approximately 240 (Group A) and 48 to 72 (Group B) subjects are expected to complete the 
26-week treatment period (assuming a 25% dropout rate).

7.1.1. Diaries
As indicated in the study schedule (Attachment 1), starting at Visit 1 (Week -3) subjects will be 
given a study diary at each office visit and instructed to record 4- point, and 7-point SMBG 
values, insulin doses, hypoglycemic episodes, adverse events (AEs), illnesses, concomitant 
medications, infusion site changes, and reasons for nonroutine infusion site changes (post-
randomization and transition to U-500R) through the end of participation in the study or at ET, if 
applicable.  Investigators should encourage subjects to measure BG values during the symptoms 
of hypoglycemia and record BG values in their study diaries.  Investigative staff will review the 
study diaries and transfer data to electronic case report forms (eCRFs) at each office visit 
beginning at Visit 2 (Week -2), with the exception of 4-point SMBG values. Investigative staff 
will also record any additional AEs and episodes of hypoglycemia that are reported by subjects 
and that have occurred since the previous entry on the eCRFs, even when the event was initially 
not entered into the study diary. Study diaries are considered source information and are to be 
returned to the investigator (or designee) at each office visit.

B5K-MC-IBHD Clinical Protocol

7.1.2. Type 2 Diabetes Lifestyle Counseling
Per the study schedule (Attachment 1), qualified medical staff will provide diabetes management 
counseling including diet, exercise, and education about the signs, symptoms, and treatment of 
hypoglycemia, should it occur.  Subjects should continue their usual exercise habits and 
generally follow stable meal plans (consistent meal size and time of day) throughout the course 
of the study.  Instruction on how to assess CHO content and caloric content of meals may be 
incorporated into the counseling.  Dietary counseling may be reviewed throughout the study as 
needed.  Subjects are not to initiate a weight loss program during the trial.
7.1.3. Blood Glucose Monitoring
The U-500R dosage will be based on subjects’ individual needs, as assessed by SMBG results
obtained from monitoring at home.  Site personnel may request additional BG monitoring from 
subjects and/or assess BG values at other times during the study in order to make dose
adjustment decisions.  Subjects should record both 4- and 7-point SMBG measurements, as well 
as insulin doses, in the subject diary provided.
4-Point SMBG
7.1.3.1.
Subjects will be instructed to record 4-point SMBGs daily beginning with the screening period.  
The 4-point SMBG consists of BG measurements at:

Pre-morning meal (fasting)

Pre-midday meal

Pre-evening meal

Bedtime (at least 2 hours after the evening meal)
7-Point SMBG
7.1.3.2.
All subjects will be instructed to record 7-point SMBG profiles on any 2 nonconsecutive days in 
the 2 weeks prior to visits as outlined in the study schedule (Attachment 1); profiles should 
include weekend day(s), if possible.  The timing of the 7-point SMBG measurement over a 
24-hour period is as follows:

Pre-morning meal (fasting)

2 hours after the morning meal

Pre-midday meal

2 hours after the midday meal

Pre-evening meal

2 hours after the evening meal

0300 hours

B5K-MC-IBHD Clinical Protocol
Page 28
LY041001
0300 Hours SMBG
7.1.3.3.
Subjects will also be instructed to record their 0300 hours BG within 48 hours of each increase in 
insulin dose titration at telephone and office visits (preferably the first night after the dosage 
adjustment).  The investigator or site personnel will ask the subjects about these BG 
measurements and the investigator will recommend dosage titrations based on glucose targets 
within the CSII (Section 9.8.1.1) and MDI (Section 9.8.2.1) algorithms during telephone and 
office visits.
7.1.4. Screening Period
This study contains a 1-week screening period between Visit 1 (Week -3) and Visit 2 (Week -2),
which allows for the evaluation and assessment of potential subjects’ eligibility against the 
inclusion and exclusion criteria (Sections 8.1 and 8.2, respectively).  Subjects may be 
prescreened for inclusion/exclusion criteria that are available from their subject files, including 
any laboratory values on file collected within the previous 30 days, in compliance with local 
privacy regulations.  Subjects will continue their pre-study insulin and AHA regimens and doses 
(per inclusion/exclusion criteria in Sections 8.1 and 8.2).  Refer to Attachment 1 for the study 
schedule of screening period activities.
7.1.5. Lead-In Period
Eligible subjects will begin a 2-week lead-in period at Visit 2 (Week -2) according to the Study 
Schedule (Attachment 1).  The lead-in period is intended to stabilize HbA1c related to study 
effect (Gale et al. 2007) and verify insulin dose.  Subjects entering the trial at Visit 1 will 
continue their pre-study insulin regimen.  Subjects will also continue taking pre-study AHA
regimens and doses (per inclusion/exclusion criteria in Sections 8.1 and 8.2) and should not 
discontinue or change doses during the study, apart from specific instructions provided in 
Section 9.11.
7.1.6. Randomization 
Study subjects who have completed all screening procedures will be randomized at a 1:1 ratio to 
the two treatment arms (U-500R CSII or MDI) using interactive web-response system (IWRS) at
Visit 4 (Section 9.6).
A review of subjects’ understanding of daily glucose monitoring and emphasis on adherence, 
4-point and 7-point SMBG profile, use of glucose meters, hypo- and hyperglycemia, and 
completion of subjects’ diary will be conducted.
7.1.7. Treatment Period
At Visit 4 through Visit 17 or ET, subjects will be treated with U-500R based on titration 
algorithms.  The total treatment period for this study will be 26 weeks (2 week transition to 
U-500R MDI administered TID, 12 weeks titration and 12 weeks maintenance U-500R CSII or 
MDI).  
During the Treatment Period, Visits 8, 9, 11, 12, 14, and 16 will be telephone visits only and 
subjects will not be required to return to the study site.  At office visits (Visits 5, 6, 7, 10, 13, 15,

B5K-MC-IBHD Clinical Protocol
Page 29
LY041001
and 17), clinical assessments and required procedures should occur as outlined in the Study 
Schedule (Attachment 1).  Adverse event and product complaint collection should occur at each 
office and telephone visit.
Apart from scheduled telephone visits, per the Study Schedule (Attachment 1), subjects will be 
instructed to call the study site office if a serious adverse event (SAE) or device-related event 
occurs, or for any concern at any time.  Specific reasons may include but are not limited to:  
hospital admission for any reason, persistent or severe hypoglycemia, recommendations for 
changes of medication from another provider, injection device or study glucose meter 
malfunction, questions about study treatment and dose changes, or scheduled surgical or dental 
procedures.
Subjects will continue taking noninsulin pre-study AHAs (per inclusion/exclusion criteria in 
Sections 8.1 and 8.2 and allowed concomitant therapies in Section 9.11) and should not 
discontinue or change doses during the study.
Transition to U-500R MDI
7.1.7.1.
A 2-week transition period is included in the 26-week treatment period and will follow 
randomization. The transition period is intended to transition all subjects safely from their 
current insulin regimen to U-500R TID 40:30:30 (Section 9.5), and to titrate U-500R according 
to the TID algorithm (Section 9.8.2.1). The highest 24-hour TDD from the past 3 days will be 
utilized for calculation of the U-500R TID dose and the dose split into the ratio of 40:30:30. 
Those subjects already on U-500R TID at entry can continue their pre-entry U-500R TID 
proportions at the discretion of the investigator.  At Visit 6 through Visit 17 or ET, subjects will 
be treated with either U-500R CSII (Section 9.8.1.1) or U-500R MDI delivered TID 
(Section 9.8.2.1) based on titration algorithms and the treatment to which they are randomized. 
U-100 Insulin Syringe for Administering U-500R MDI
7.1.7.2.
All subjects will receive training on the appropriate use of U-100 insulin syringes for drawing up 
and administering correct doses of U-500R, including the conversion of insulin units of U-500R 
to the unit markings (one-fifth of actual volume) on the U-100 insulin syringe (Section 9.7.1).
CSII Pump Training
7.1.7.3.
Subjects assigned to U-500R CSII treatment will receive training on the OmniPod U-500 system
at 2 visits (Visit 5 [Week 1] and Visit 6 (Week 2).  At Visit 5, subjects will be introduced to the 
basics of pump usage (ie, basal rates, boluses, and filling Pods).  At Visit 6, subjects will receive 
hands-on training on the U-500 OmniPod System.  Additional subject training can be considered 
at the investigator’s discretion after consulting with Lilly clinical research physician 
(CRP)/clinical research scientist (CRS) (Section 9.7.2).
7.2.
Discussion of Design and Control
This is a randomized, open-label, parallel study comparing U-500R administered by CSII 
(OmniPod U-500 system) to U-500R administered by MDI in high-dose insulin-requiring
patients with T2DM who have inadequate glycemic control on existing high-dose non U-500R 
(>200 and ≤600 units per day) insulins (CSII or MDI), and/or U-500R insulin MDI with or 

B5K-MC-IBHD Clinical Protocol
Page 30
LY041001
without other insulins/AHAs.  Delivery of U-500R insulin by CSII in currently marketed insulin 
pumps requires dose conversion to “U-100 pump units” (one-fifth of U-500R insulin dose per 
volume), which potentially could result in dosing confusion.  The OmniPod Insulin Management 
System for use with U-500 insulin (OmniPod U-500 system) software has been developed so that 
1 unit of insulin is delivered with every 4 pulses of the drive mechanism (for example, the 
OmniPod U-500 system would deliver 0.25 units per pulse compared to 0.05 units per pulse in 
the conventional U-100 OmniPod insulin pump).  The volume delivered in 1 pulse is the same 
for the U-100 and U-500 insulin pumps; thus due to higher concentration, fewer pulses are 
required by the U-500 pump to deliver the same insulin dose (4 pulses for 1-unit for U-500 
insulin versus 20 pulses for 1-unit for U-100 insulin).  
The majority (86%) of patients currently using U-500R have T2DM (Eby et al. 2013).  Because 
patients with type 1 diabetes mellitus (T1DM) constitute a small proportion of U-500R users and 
could have a different response to the algorithms and/or CSII delivery system, they are excluded 
from this study.
The total treatment period for this study will be 26 weeks.  The 26-week duration of treatment in 
this study was selected because it allows enough time for insulin therapy to be intensified, and 
permits sufficient time to show glycemic improvement and stabilization as measured by HbA1c, 
FPG, SMBG values, and TDD.  
After Visit 1 (screening), subjects who meet all of the inclusion criteria (Section 8.1) and none of 
the exclusion criteria (Section 8.2) will remain on their pre-study treatment for a 2 week lead-in 
period at Visit 2 (Week -2).  This lead-in period is intended to stabilize HbA1c related to study 
effect (Gale et al. 2007) and verify actual insulin dose.  Following the lead-in, subjects will be 
randomized at Visit 4 (Week 0) in an open-label fashion based on a 1:1 ratio to U-500R 
treatment by MDI or U-500R treatment by CSII.  A 2-week transition to U-500R by MDI 
administered TID, regardless of insulin or combination thereof at Visit 2 (Week -2) (Section 9.5) 
will begin after randomization (Visit 4 [Week 0]) utilizing the TID algorithm with weekly 
titrations (Section 9.8.2.1).  The transition period is to ensure safe transition to U-500R insulin 
from entry insulin (as applicable).  After completion of the 2-week transition period, 24-weeks of 
U-500R delivered by MDI versus CSII will begin. 
The primary and key secondary objectives will be assessed in subjects from Group A (without
use of GLP-1 receptor agonists or SGLT2 inhibitors) and combined for the total study population 
Group A and Group B (those who use GLP-1 receptor agonists or SGLT2 inhibitors). 
The study will be performed open-label since blinding of the investigators, subjects, and study 
site personnel could not be accomplished given the differing modes of delivery of U-500R (CSII 
versus MDI). To minimize bias, aggregate review of summary data by the study team (that is, 
CRP/CRS overseeing the global conduct of the study, statisticians, and statistical analysts) will 
remain blinded until after the final database is locked (Section 9.10).

8. Study Population
Individuals who do not meet the inclusion criteria for participation in this study (screen failure) 
may be re-screened once.  The interval between screen and re-screen should be at least 2 weeks.  
When re-screening is performed, the individual must sign a new informed consent form (ICF) 
and will be assigned a new identification number.
Entered subjects who meet all inclusion criteria ([1] through [7]) and are not excluded by 
exclusion criteria ([8] through [28]) will initiate the lead-in period at Visit 2 (Week -2).
Prior to randomization at Visit 4, all subjects will be re-confirmed for inclusion criteria [1], [2]
and [7] and exclusion criteria [18].
Prospective approval of protocol deviations to recruitment and enrollment criteria, also known as 
protocol waivers or exemptions, is not permitted.

B5K-MC-IBHD Clinical Protocol
Page 34
LY041001
Are unwilling or unable to independently perform study procedures, such as 
[28]
monitoring SMBG levels, recording diary data, and/or administering medication 
via syringe or CSII as applicable, or have any illness or condition (including 
known drug or alcohol abuse or psychiatric disorder) within the 6 months prior to 
Visit 1, that precludes subject from following and completing the protocol 
according to the investigator’s judgment.  Subjects may not use a proxy to 
perform collection procedures, administer medication, or record data.
8.2.1. Rationale for Exclusion of Certain Study Candidates
Exclusion criterion [8] ensures that subjects with T1DM or other types of diabetes (except 
T2DM) will be excluded from the study due to the potentially different response to the 
algorithms and/or device.  Exclusion criteria [9], [10], [13], [14], [16], [17], [21], and [23]
represent clinical situations that may prevent subjects from completing the protocol, or may 
influence the efficacy or safety of study regimens, or are serious conditions that pose a risk for 
morbidity and mortality.  Exclusion criterion [11] addresses the potential difficulty of 
distinguishing if severe hypoglycemia is related to study drugs, or to counter-regulatory 
deficiencies, or to the natural history of the disease in subjects with recurring episodes.  
Exclusion criterion [12] relates to the potential of sub-optimal glycemic control and possible
changes in quality of life when changing from U-500R CSII therapy.  Exclusion criterion [15]
relates to the negative effect of steroid therapy on the management of diabetes and need for 
altered dosing titration of insulin.  Exclusion criterion [18] excludes medications that are 
restricted by product label (exenatide), may cause HbA1c-lowering not attributable to the study 
insulin regimens or the combination of AHAs being studied, or which could confound 
interpretation of the results, or may influence the safety of study regimens.  Exclusion criteria
[19], [20] and [27] prevent a situation in which positive or negative outcomes may not be clearly 
attributable to the regimens in this study.  Exclusion criterion [22] would prevent the subject 
from safely using the OmniPod U-500 system.  Exclusion criterion [24] ensures the safety of 
unborn or newborn children.  Exclusion criteria [25] and [26] reduce potential bias due to 
conflict of interest.  Exclusion criterion [28] excludes subjects who may be unwilling or unable 
to perform study procedures per protocol instructions for their safety.
8.3.
Discontinuations
8.3.1. Discontinuation of Inadvertently Enrolled Subjects
The criteria for enrollment must be followed explicitly.  If the investigator site identifies a 
subject who did not meet enrollment criteria and who was inadvertently enrolled, the sponsor 
must be notified.  If the sponsor identifies a subject who did not meet enrollment criteria and 
who was inadvertently enrolled, the investigator site will be notified.  A discussion must occur 
between the sponsor CRP/CRS and the investigator to determine whether the subject may 
continue in the study, with or without study treatment.  Inadvertently enrolled subjects may be 
maintained in the study and on study treatment when the Lilly CRP/CRS agrees with the 
investigator that it is medically appropriate for that subject. The subject may not continue in the 
study with or without study treatment if the Lilly CRP/CRS does not agree with the 

B5K-MC-IBHD Clinical Protocol
Page 35
LY041001
investigator’s determination it is medically appropriate for the subject to continue.  The 
investigator must obtain documented approval from the Lilly CRP/CRS to allow the 
inadvertently enrolled subject to continue in the study with or without study treatment.
8.3.2. Discontinuation of Study Treatment
Subjects will be discontinued from the study treatment in the following circumstances:

If Exclusion Criteria [9] (with the exception of the hepatic laboratory values; 
Section 10.4.5), [11] to [15], [18] to [21], [23] and [24] are observed or 
develop after study enrollment, the subject will be discontinued from the study 
treatment at the next visit or sooner. 

If in the investigators judgment, the subject is not at least 80% compliant with 
study treatment (i.e.; investigator recommended dose adjustments based on 
algorithms)

If the subject is off study medication for more than 7 consecutive days during 
the study treatment period.
In the event that the subject is discontinued from the study treatment, the investigator should 
encourage the subject to remain in the study for continued safety monitoring. 
8.3.3. Subject Discontinuation from the Study
If exclusion criterion [25] through [28] is observed or develops after entry or enrollment,
the subject will be discontinued from the study at the next site visit or sooner in the event 
of a safety exclusion criterion.  
Subjects who discontinue the study early will have ET procedures performed as shown in the 
Study Schedule (Attachment 1).  For information as to how efficacy and safety analyses will be 
conducted for subjects who are discontinued from study treatment, see Sections 12.2.3 and
12.2.10, respectively.
The subject may be discontinued from the study if:

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.

Investigator decision
o
The investigator decides that the subject should be discontinued from the study
(this can be for safety reasons, such as for recurrent hypoglycemia, or it can be for 
any reason).
o
If the subject, for any reason, requires treatment with another therapeutic agent 
that has been demonstrated to be effective for treatment of the study indication, 
discontinuation from the study occurs prior to introduction of the new agent.

Subject decision 
o
The subject requests to be withdrawn from the study.


Sponsor decision
o
Lilly or its designee stops the study or stops the subject’s participation in the 
study for medical, safety, regulatory, or other reasons consistent with applicable 
laws, regulations, and good clinical practice (GCP).

Adverse event 
o
If the investigator decides that the subject should be withdrawn because of a SAE, 
treatment emergent adverse event (TEAE), or a clinically significant laboratory 
value, study treatment is to be discontinued and appropriate measures are to be 
taken.  Lilly or its designee is to be alerted immediately.  Refer to Safety 
Evaluations Section 10.4.
8.3.4. Subjects Lost to Follow-Up
A subject will be considered lost to follow-up if he or she repeatedly fails to return for scheduled 
visits and is unable to be contacted by the study site.  Site personnel are expected to make 
diligent attempts to contact subjects who fail to return for a scheduled visit or were otherwise 
unable to be followed up by the site.
Site personnel, or an independent third party, will attempt to collect the vital status of the subject
within legal and ethical boundaries for all subjects randomized, including those who did not get 
study treatment.  Public sources may be searched for vital status information.  If vital status is 
determined, this will be documented and the subject will not be considered lost to follow up.
Lilly personnel will not be involved in any attempts to collect vital status information.
8.3.5. Discontinuation of Study Sites
Study site participation may be discontinued if Lilly, the investigator, or the ethical review board 
(ERB) of the study site judges it necessary for medical, safety, regulatory, or other reasons 
consistent with applicable laws, regulations, and GCP.
8.3.6. Discontinuation of the Study
The study will be discontinued if Lilly judges it necessary for medical, safety, regulatory, or 
other reasons consistent with applicable laws, regulations, and GCP.

The investigator or his/her designee is responsible for the following:

explaining the correct use of the investigational agent(s) to the subject/site 
personnel,

verifying that subject clearly understands instructions and is able to demonstrate 
understanding, maintaining accurate records of study treatment dispensing and 
collection, and returning all unused medication or devices to Lilly or its designee 
at the end of the study.
Note:  In some cases, sites may destroy the material if, during the investigator site selection, the 
evaluator has verified and documented that the site has appropriate facilities and written 
procedures to dispose of clinical trial materials.  In all other cases, the site has to return used or 
unused material to Lilly or designee.
Subjects will be instructed to contact the investigator as soon as possible if he or she has a 
complaint or problem with study treatment or drug delivery system so that the situation can be 
assessed.
9.2.
Materials and Supplies
Subjects should continue taking their noninsulin pre-study AHA doses throughout the study, as 
applicable.  Pre-study AHAs must be used as described in their respective product labeling.
Supplies and appropriate instructions for use will be provided for both treatment groups 
beginning at screening Visit 1 (Week -3). Study drug and additional supplies will be provided at 
Visits 4, 5, and as needed thereafter per the Study Schedule (Attachment 1).
Subjects will be assigned to treatment arm at randomization Visit 4 (Week 0).  Appropriate pump 
training will be provided for the CSII group (Section 9.7.2).  The OmniPod U-500 system

supplies for infusion including PDM and Pod with fill syringe will be provided at Visit 6 
(Week -2) and as needed thereafter per the study schedule.  
U-500R will be provided in 20-mL vials (10,000 U) for use by CSII or MDI.  Unopened U-500R
vials or U-500R vials not in-use should be stored in a refrigerator (2° to 8°C [36° to 46°F]), but 
not in the freezer. Once opened, the U-500R vial can be kept unrefrigerated as long as it is kept 
as cool as possible (below 30°C [86°F]) and away from heat and light.  In-use vials must be used 
within 40 days or be discarded, even if they still contain U-500R.  
The respective labeling information will be provided with the insulin pump and supplies, the 
disposable syringes, and the study drug as applicable.  In addition, a commercially available BG 
meter will be provided with necessary supplies and instructions at Visit 1 (Week -3). Clinical 
trial materials will be labeled according to the respective country’s regulatory requirements.

Method of Assignment to Treatment
Subjects will continue on their pre-study insulin regimens until Visit 4 (Week 0). After re-
confirmation of eligibility, subjects who meet specific criteria (Section 8) for enrollment will be 
randomized at Visit 4 (Week 0) to open-label treatment with U-500R administered by one of two 
treatment regimens:  MDI or CSII. However, subjects randomized to CSII will not initiate U-
500R administered by CSII until transition to U-500R is complete (Section 9.7). Assignment to 
treatment arms will be determined by a computer-generated random sequence using an IWRS.  
9.4.
Rationale for Selection of Doses in the Study
Protocol IBHD dosing transition to U-500R MDI and titration regimens for the CSII and MDI
treatment groups are guided by initial insulin TDD (based on the highest TDD recorded in the 
3 days before Visit 2), screening HbA1c (Visit 1), subsequent glucose monitoring, literature 
expert reviews (Lane 2006; Lane et al. 2009; Hirsch 2010, Lane et al. 2010; Segal et al. 2010; 
Reutrakul et al. 2012), efficacy and safety results from one Phase 4 clinical study 
(B5K-US-IBHC [Hood et al, 2015]), results from simulations performed using a systems 
physiology model of diabetes (Entelos PhysioLab® Modeler) based on data from previous 
pharmacodynamics/pharmacokinetics studies (de la Peña et al. 2011) of U-500R and U-100 
Humulin regular insulin) and on expert protocol consultant advice.
Fasting and bolus for CSII and MDI therapy plasma-equivalent glucose target ranges are 80 to
140 mg/dL. Recommended administration of U-500R bolus doses, within approximately

B5K-MC-IBHD Clinical Protocol
Page 39
LY041001
30 minutes before meals by CSII or MDI dosing, is based on label advice and recent 
pharmacodynamics/pharmacokinetics study results in obese, healthy subjects that demonstrate 
both prandial and basal activity of U-500R (de la Peña et al. 2011).  Administration of U-500R 
bolus doses 15 minutes before meals will be assessed in a subset of subjects participating in the 
continuous glucose monitoring (CGM) addendum to demonstrate glycemic impact.  If the shorter 
bolus time period is found to be equally efficacious, there may be a potential benefit on
adherence.
9.5.
Lead-in Period 
The 2-week lead-in period of the trial includes the interval between Visit 2 and Visit 4.  
Subjects’ current diet (particularly caloric intake) and exercise levels will be reviewed during 
lead-in and at subsequent visits throughout the study, as needed, to assess adherence to the 
lifestyle advice discussed at Visit 2 (Week -2) as part of subject training and education.  Subjects 
should be encouraged to eat 3 meals a day plus a snack before bedtime (21 grams CHO Extend 
Bar®, Extend Nutrition, St. Louis, MO or equivalent) to support U-500R dosing per CSII or MDI
during the study.  
Subjects will continue taking prestudy AHAs and doses (per inclusion/exclusion criteria in 
Sections 8.1 and 8.2 and allowed concomitant therapies in Section 9.11) and should not 
discontinue or change doses during the study. Refer to Study Schedule for details of events 
(Attachment 1).
9.6.
Randomization
At Visit 4 (Week 0), if subjects have been re-confirmed for trial eligibility (Section 8), they will 
be randomized at a 1:1 ratio to the two treatment arms (CSII or MDI) using IWRS (Section 9.3). 
Subjects will be stratified by entry HbA1c ≥8.5% or <8.5%, nonusers versus users of GLP-1
receptor agonists or SGLT2 inhibitors, and U-500R at entry versus other insulins.
Subjects in the study will continue taking noninsulin pre-study AHA regimens (per 
inclusion/exclusion criteria in Sections 8.1and 8.2) and allowed concomitant therapies. Subjects 
should not discontinue or change doses during the study (Section 9.11).  Subjects will transition 
to U-500R MDI for 2 weeks and then initiate 24 weeks of CSII or MDI treatment (Section 9.7).
Subjects who discontinue prior to randomization will be considered screen failures.  No ET 
activities will be applicable.
9.7.
Transition to U-500R MDI 
All subjects will administer U-500R MDI delivered TID (40:30:30 unless otherwise noted) 
during the transition period (Weeks 0-2).  Transition to U-500R MDI will follow the criteria 
below in Table IBHC.9.3.  Subjects will have their insulin adjusted weekly by the investigator 
using the algorithm from Section 9.8.2.1.

Abbreviations: HbA1c = hemogloblin A1c; SMBG=self-monitored blood glucose; MDI = multiple daily injections;

Subjects treated with U-100 and/or other concentrated insulin (with or without U-500R) at 
screening Visit 1 (Week -3) with HbA1c levels >8% and a mean SMBG (recorded prior to 
Visit 4 [Week 0]) value >183 mg/dL (corresponding to HbA1c value of >8.0% [estimated 
average glucose; Nathan et al. 2008]) at Visit 4 should be transitioned to U-500R using 1:1 
dosage conversion.  
Subjects treated with U-100 and/or other concentrated insulin (with or without U-500R) at 
screening Visit 1 (Week -3) with HbA1c levels >8% and a mean SMBG (recorded prior to 
Visit 4 [Week 0]) value ≤183 mg/dL (corresponding to HbA1c value of ≤8.0%) at Visit 4, should 
transition by reducing their U-500R TDD by 20%.
Subjects treated with U-100 and/or other concentrated insulin (with or without U-500R) at 
screening Visit 1 (Week -3) with HbA1c ≤8% should transition to U-500R at Visit 4 (Week 0)
by reducing their U-500R TDD by 20%, regardless of SMBG value.
Subjects treated with U-500R insulin only at screening Visit 1 (Week -3) should transition to 
U-500R TID with proportion 40:30:30 using a 1:1 dosage conversion at Visit 4 (Week 0), 
regardless of HbA1c and/or SMBG.  Those subjects already on U-500R TID at entry can 
continue their pre-entry U-500R TID proportions at the discretion of the investigator. 
Investigators may also deviate from the proportion, if deemed necessary, for the safety or 
well-being of the subject (that is, due to a safety concern).  Any major deviation from the 
recommended proportion must be discussed with Lilly CRP/CRS.
9.7.1. Dosing Using U-100 Insulin Syringes
The units marked on a U-100 insulin syringe do not accurately reflect the unit dose of U-500R 
insulin because U-500R is 5 times more concentrated than U-100 insulin, and thus only one-fifth
of the volume is needed to give an equivalent dose to U-100 insulin.  Site personnel should 
instruct subjects on the dose conversion of calculated U-500R to the U-100 insulin syringe unit 
markings (examples below and conversion charts are also provided in the U-500R package insert
and Subject Information on U-500R).
The U-100 insulin 0.5 mL syringes should be used for administration for all U-500R doses 
≤250 U.  All U-500R doses >250 units should be administered using 1.0 mL U-100 insulin 
syringes. 

B5K-MC-IBHD Clinical Protocol
Page 41
LY041001
For example:

155 units of U-500R has a volume equivalent to 31 units markings on a 0.5 mL 
U-100 insulin syringe (155 divided by 5=31).

100 units of U-500R has a volume equivalent to 20 units markings on a 0.5 mL 
U-100 insulin syringe (100 divided by 5=20).

300 units of U-500R has a volume equivalent to 60 units markings on a 1.0 mL 
U-100 insulin syringe (300 divided by 5=60).
9.7.2. CSII Training 
Subjects randomized to the CSII treatment arm will be trained on the use of the OmniPod U-500 
system after randomization at Visits 5 and 6 (Weeks 1 and 2). CSII training will include but not 
be limited to pre-pump training regarding basal rates and bolus dosing, initial PDM and Pod 
setup, setting basal rates (including temporary basal rate) and boluses (CHO counting, fixed 
dosages or meal sizes), and responding to hazard alarms. The OmniPod U-500 system basics of 
pump usage (ie, basal rates, boluses, and filling Pods) will be introduced to subjects at Visit 5 
(Week 1) and the hands on training will occur at Visit 6 (Week 2) (Section 7.1.7.3.).
9.7.3. Intensified Dose Titration Period
The 12-week intensified dose titration period of the trial will extend from Visit 6 (Week 2) to 
Visit 13 (Week 14) and will include investigator-driven dosage titration according to the 
titration algorithms (Sections 9.8.1.1 and 9.8.2.1) at weekly intervals starting on Visit 6 through 
8 (Weeks 2 through 4) and biweekly starting at Visit 9 through 13 (Weeks 6 through 14) 
(Attachment 1).  Additional dosage titrations per algorithms may be made more frequently if 
needed per investigator’s judgment during this period.
9.7.4. Maintenance Dose Titration Period
The 12-week maintenance dose titration period of the trial will extend from Visit 13 (Week 14) 
to the final visit, Visit 17 (Week 26) or ET visit.  Dose titrations by the investigator will be 
completed in an identical manner to those during the intensified dose titration period 
(Sections 9.8.1.1 and 9.8.2.1) but will be at 3-week intervals (Attachment 1).  Additional dosage 
titrations per algorithms may also be made more frequently if needed per investigator’s judgment 
during this period.
9.8.
Treatment Periods
9.8.1. CSII
The OmniPod U-500 system is designed to deliver U-500 insulin in insulin units without 
converting to U-100 insulin ‘pump units’ (Section 7.2).  Beginning at Visit 6 (Week 2), all CSII 
subjects will be instructed to change their OmniPod U-500 system Pod every 2 to 3 days
(depending on TDD) during the treatment period.  Subjects will be instructed to inspect Pod 
cannula insertion sites for signs of redness, swelling, or leakage and to respond to any CSII 
alarms (Bolderman et al. 2013).

B5K-MC-IBHD Clinical Protocol
Page 42
LY041001
For subjects randomized to CSII: 

The OmniPod U-500 system Pod should be filled in the clinic with U-500R 
during Visit 6.

The highest 24-hour TDD from the past 3 days will be utilized for calculation of 
the CSII doses.  

50% of the TDD will be basal split into 2 rates:
o
2100 to 0600 hours 10% basal rate reduction  
o
0600 to 2100 hours for the calculated basal rate 

50% of the TDD will be bolus split into the following ratio:
o
40:30:30 (Section 9.8.1.3) for fixed bolus doses.
o
Suggested initial setting for insulin:  CHO ratio should be programmed between
1:3 and 1:5.
CSII Treatment Group Algorithms
9.8.1.1.
Subjects in the CSII group will have their basal rates (Table IBHD.9.4) and bolus doses 
(Table IBHD.9.5) adjusted at each study visit (office and telephone) by the investigator
according to the CSII titration algorithms. Investigators may deviate from the algorithms, if 
deemed necessary, for the safety or well-being of the subject (that is, due to illness or other 
safety concern).  Any major deviation from the algorithm must be discussed with Lilly. The 
CSII bolus titration scheme (Table IBHD.9.5) will be divided into 2 dosing bins:  TDD 
<400 units and TDD ≥400 units.  Subjects will have their U-500R adjusted according to the TDD 
at the time of adjustment.
Subjects taking <400 units TDD at Visit 6 (Week 2) should use a 1:10 correction factor with a 
target of 100 mg/dL starting at 25 mg/dL above target for all mealtime boluses.  Subjects taking 
≥400 units TDD at Visit 6 (Week 2) should use a 1:5 correction factor with a target of 
100 mg/dL starting at 25 mg/dL above target for all mealtime boluses.  If, in the opinion of the 
investigator, the subject would benefit from a different correction factor, the investigator should 
discuss this with the Sponsor.  
Note:  Subjects should be instructed to hold their U-500R bolus dose if a meal is skipped.

(preferably most recent 3 days).
b
Any plasma glucose (SMBG or lab) measurement <50 mg/dL, investigator should reduce corresponding bolus 
dose by 10-20% as soon as it occurs or notification of the reading occurs. 
c
If the algorithm adjustment leads to overlapping basal and bolus adjustments, the investigator has the discretion 
to reduce the bolus adjustment for safety.
d
If the subject is using CHO meal sizes or CHO counting for boluses and their SMBGs are not in the target range 
for the corresponding meal at the visits (telephone or office) for algorithm titrations, then the principal 
investigator should adjust (increase or decrease) the insulin CHO ratio by approximately 10% to 15%.
e
In the event that nocturnal hypoglycemia occurs requiring a reduction in the overnight basal rate, the investigator 
may reduce the pre-dinner dose even if the bedtime SMBG median is in the target range of 80-140 mg/dL.
Note:  All CSII basal and bolus doses will be rounded to the nearest 0.25 units.

B5K-MC-IBHD Clinical Protocol
Page 44
LY041001
CSII Basal Rate
9.8.1.2.
The overnight basal rate from 2100 to 0600 hours is adjusted based on the median fasting pre-
breakfast SMBG from the past 3 values (most recent 3 days recommended) and the basal rate 
from 0600 to 2100 hours is adjusted based on pre-dinner SMBG (most recent 3 days 
recommended).  The principal investigator may increase the number of basal rates up to 4 basal 
rates during the trial, if in the investigator’s opinion the subject needs further individualization of 
basal rates based on blood sugar trends, such as nocturnal hypoglycemia or the dawn 
phenomenon indicating a need for the change(s).
9.8.1.2.1. Adding a Basal Rate for Nocturnal Hypoglycemia
If a subject has persistent nocturnal hypoglycemia, an additional basal rate reduction can be 
added.  For example, if a subject has persistent nocturnal hypoglycemia between 2100 hours and 
midnight after the initial 10% reduction in the basal rate between 2100 and 0600 hours, an 
additional basal rate reduction can be added in the time period from 2000 hours to midnight (that 
is, 20% reduction between 2000 hours and midnight with 10% reduction continuing between 
midnight and 0600 hours).  Alternatively, the investigator may decide to suspend the basal rate 
overnight.
9.8.1.2.2. Adding a Basal Rate for Dawn Phenomenon
If a subject has significant dawn phenomenon leading to persistent hyperglycemia, an additional 
basal rate increase can be added based on investigator discretion.  For example, if a subject has 
persistent hyperglycemia from 0600 to 1000 hours, an additional basal rate increase of 10% can 
be added from 0600 to 1000 hours.
CSII Bolus Dosing
9.8.1.3.
Subjects should bolus 30 minutes prior to meals except for a subset of the subjects in the CGM 
addendum who will be assigned to bolus 15 minutes prior to meals.  
Subjects should be encouraged to eat a bedtime snack (Extend Bar 21 gm CHO or equivalent)
without administering a bolus for the snack.  Note:  If the subject has an allergy or intolerance to 
the Extend Bar, then the subject may substitute a bedtime snack between 15 and 25 grams CHO.
9.8.1.3.1. CSII Bolus Settings
The investigator has the option of prescribing 3 bolus options. Table IBHD.9.5 should be 
followed for dosage adjustments. The U500 OmniPod system bolus calculator should be set to 
one of the following bolus options (according to principal investigator discretion):

Use fixed bolus regimen based on previous mealtime insulin requirements.  Bolus 
dose will be imputed manually (that is, the user would enter their BG value and 
answer ‘use for bolus calcs?’ with ‘yes’; answer ‘are you going to eat now’ with
‘no’ and then override the suggested bolus based on the fixed bolus dose size). 

A mealtime bolus utilizing CHO meal sizes. Adjust dose based on a preset CHO meal 
size (for example:  small = 30 gram CHO; medium = 60 gram CHO; and large = 90 gram 
CHO).

A mealtime bolus for the corresponding meal if the subject is using CHO counting.

B5K-MC-IBHD Clinical Protocol
Page 45
LY041001
Note: Subjects should be encouraged to maintain the bolus option throughout the study.
All subjects should have the insulin-on-board (IOB) setting programmed at 6 hours except for a 
subset of the subjects participating in the CGM Addendum who will have the IOB set at 8 hours. 
The clinical protocol addendum will assess alternative IOB based on U-500R time action profile.
9.8.2. MDI
For MDI subjects, initial doses of U-500R will be determined according to Section 9.7; dosage 
titrations per bolus titration schedule (Table IBHD.9.6) will occur at the same visits (telephone or 
office) as for CSII subjects.  
MDI subjects should also bolus U-500R 30 minutes prior to meals except for a subset of 
the subjects participating in the CGM addendum who will bolus 15 minutes prior to 
meals.  
Subjects should be instructed to eat a bedtime snack (Extend Bar 21 gm CHO or 
equivalent).
Subjects should be instructed to use a U-100 insulin syringe to draw up the U-500R dose
(Section 9.7.1).  All bolus doses will be rounded to the nearest 5 units.
MDI Treatment Group Algorithms
9.8.2.1.
Subjects in the MDI group will have their insulin dosages adjusted at each study visit (office and 
telephone) by the investigator according to the TID titration algorithm (Table IBHD.9.6).  The 
MDI bolus titration scheme will be divided into 2 dosing bins; TDD <400 units and TDD 
≥400 units.  Subjects will have their U-500R adjusted according to the TDD at the time of 
adjustment.
Note:  Subjects should be instructed to reduce their U-500R dose by 50% if a meal is skipped.

Special Treatment Considerations 
9.9.1. Rescue Therapy
Rescue therapy should be initiated in the following circumstances:

If median of 3 fasting SMBG >300 mg/dL over a 3-day period is unexplained from 
previous week, starting at Visit 10 through Visit 13 (Weeks 8 through 14).

If HbA1c value at Visit 13 (Week 14) is ≥10.0% and decreased by <0.4% compared to 
Visit 10 (Week 8) HbA1c.

If HbA1c value at Visit 15 (Week 20) is ≥10.0% and decreased by <0.4% compared to 
Visit 13 (Week 14) HbA1c.
Subjects receiving U-500R MDI will be rescued by the addition of a bedtime U-500R dose 
(increase injections to 4-times daily therapy).  A suggested starting dose for the rescue dose 
would be 10% of TDD, but this may be modified based on investigator judgment.
Subjects receiving CSII U-500R will be rescued by the addition of a bedtime U-500R dose 
delivered by CSII.  A suggested starting dose for the rescue dose would be 5% to 10% of TDD, 
but this may be modified based on investigator judgment.
Subjects should be instructed to record their 0300-hour BG within 24 hours after adding a rescue 
dose and subjects should also be encouraged to record their 0300-hour BG 2 to 3 times the first 
2 weeks after adding a rescue dose.
Every attempt should be made to keep these subjects in the study.  Change in treatment regimen 
should be recorded in the eCRF.

9.9.2. Continued Access to Study Treatment
The U-500R insulin used in this study is commercially available in the US and is therefore 
available for subjects after the conclusion of this study.
9.10. Blinding
This is an open-label study.  Treatment blinding of the investigators, subjects, and study site 
personnel is not feasible due to differences in the appearance and functionality of the delivery 
devices.  To minimize bias, aggregate review of summary data by the study team (that is, 
CRP/CRS overseeing the global conduct of the study, statisticians, and statistical analysts) will 
remain blinded until after the final database is locked. Unblinding of the subject study treatment 
assignment may occur in the course of individual subject consultation between the investigator 
and the study team (principally between the investigator and the CRP/CRS) or during review of 
SAEs. No systematic unblinding of study treatment assignments will be solicited by the study 
team.  
9.11. Concomitant Therapy
All concomitant therapies that are part of routine care are allowed and may be used during the 
study with the exception of those specifically outlined in Sections 8.1 and 8.2.  Subjects who 
take any excluded concomitant therapy will be discontinued from the study treatment at the next 
visit or sooner.  In emergency/urgent situations, subjects may cease taking study medication for 
7 consecutive days and may be treated instead with nonstudy insulin during that time.  If a 
subject takes nonstudy insulin for more than 7 consecutive days, then discontinuation criteria 
apply (Section 8.3.2).
9.11.1. Concomitant Medications Including Antihyperglycemic Agents
Subjects will be allowed to continue to use any concomitant medications with the exception of
those listed in the exclusion criteria.  A list of selected concomitant medications that have an 
effect on glucose metabolism, and their conditions for use, is presented in Table IBHD.9.7.  The 
subject should be encouraged to report any new concomitant medications after initiating the 
medication.  Please check with the study team if you have any concerns or questions about a 
medication the subject is taking.

9.12. Treatment Compliance
Subject compliance with study medication will be assessed at each applicable study visit.  
Compliance will be based on adherence to the Study Schedule (Attachment 1), compliance with 
appropriate assigned injection method (CSII versus MDI), completion of the subject’s diary, and 
any other parameters the investigator deems necessary.  Compliance will be assessed by direct 
questioning and returned study materials.  
Subjects who are deemed significantly noncompliant will be discontinued from the study
treatment.  A subject will be considered significantly noncompliant if he or she:

misses more than 7 consecutive days of study medication during the study. 

is judged by the investigator to have intentionally or repeatedly taken more than the 
prescribed amount of medication that may cause patient safety concerns. 

is not at least 80% compliant with study treatment (ie, PI recommended doses 
adjustments based on algorithms).

Efficacy, Patient Reported Outcomes, Safety 
Evaluations, Sample Collection and Testing, and 
Appropriateness of Measurements
Study procedures and their timing (including tolerance limits for timing) are summarized in the 
Study Schedule (Attachment 1).
10.1. Efficacy Measures 
10.1.1. Primary Efficacy Measure
The primary efficacy measure for this study is change in HbA1c from baseline (last nonmissing 
value at or prior to the treatment starting Visit 4) to the 26-week value.
10.1.2. Secondary Efficacy Measures
The following secondary efficacy measures will be collected at the times shown in the Study 
Schedule (Attachment 1).  The secondary objectives are summarized in Section 6.2.
Fasting Plasma Glucose
10.1.2.1.
Change in mean FPG levels will be compared between treatments.
7-point SMBG
10.1.2.2.
Mean plasma glucose will be analyzed for each individual time point using the 7-point SMBG.  
The 7-point SMBG is a subject self-administered plasma glucose test that utilizes measurements 
at specific time points over a 24-hour period.  The timing of the 7-point SMBG measurement is 
described in Section 7.1.3.2.
Total Daily Insulin Dose
10.1.2.3.
Change in TDD (unit and unit/kg) as basal/bolus for the CSII arm and by bolus dosing for the 
MDI arm from baseline to 26-week value will be calculated and analyzed.
10.2. Patient Reported Outcomes
The self-reported questionnaires will be administered, according to the Study Schedule 
(Attachment 1).  
10.2.1. TRIM-D and TRIM-D Device
The TRIM-D and TRIM-DD scales are valid and reliable patient-reported outcome (PRO) 
measures, which capture the full range of impact of diabetes treatment on subject functioning 
and well-being across T1DM and T2DM subjects, as well as across all currently available 
delivery systems and treatments (oral agents, GLP-1 receptor agonist pens, inhaled- or pump-
delivered insulin, and insulin delivered with syringe/pens) (Brod et al. 2009).  The TRIM-D 
consists of 28 items, and the TRIM-DD consists of 8 items.  In both of these PROs, items are 
measured on a 5-point scale, where the higher score indicates a better health state.  In addition to 
an overall score, the TRIM-D items make up the 5 domains of impact:  Treatment Burden 
(6 items), Daily Life (5 items), Diabetes Management (5 items), Compliance (4 items), and 

B5K-MC-IBHD Clinical Protocol
Page 50
LY041001
Psychological Health (8 items).  In addition to an overall score, the TRIM-DD items include the 
domain’s device function (5 items) and bother of device (3 items).
The TRIM-D and TRIM-DD will be administered at Visit 4 (Week 0, prior to randomization), at 
Visit 13 (Week 14) and at Visit 17 (Week 26) or ET if subjects do not complete the full 26 weeks 
of the study.
10.3. OmniPod U-500 System Exit Questionnaire
An OmniPod U-500 system exit questionnaire will be administered to subjects in the CSII group 
at Visit 17 (Week 26) or at ET if subjects terminate.
10.4. Safety Evaluations
Investigators are responsible for monitoring the safety of subjects who have entered this study 
and for alerting Lilly or its designee to any event that seems unusual, even if this event may be 
considered an unanticipated benefit to the subject.
The investigator is responsible for the appropriate medical care of subjects during the study.
The investigator remains responsible for following, through an appropriate health care option, 
AEs that are serious, considered related to the study treatment or the study, related to the study 
device (U-500 OmniPod system), or that caused the subject to discontinue before completing the 
study.  The subject should be followed until the event is resolved or explained.  Frequency of 
follow-up evaluation is left to the discretion of the investigator.
Safety evaluations include the following:

Frequency and incidence of AEs and TEAEs

Incidence/rate of hypoglycemia (documented [documented symptomatic, 
asymptomatic, and unspecified], severe, and nocturnal)

Body weight

Vital signs

Study treatment exposure

Clinical laboratory tests abnormalities

Product complaints
10.4.1. Adverse Events
Lilly has standards for reporting AEs that are to be followed regardless of applicable regulatory 
requirements that may be less stringent.  
Lack of drug effect is not an AE in clinical studies because the purpose of the clinical study is to 
establish drug effect.

B5K-MC-IBHD Clinical Protocol
Page 51
LY041001
Cases of pregnancy that occur during maternal or paternal exposures to study treatment or drug 
delivery system should be reported.  Data on fetal outcome and breastfeeding are collected for 
regulatory reporting and drug safety evaluation.
Study site personnel will record the occurrence and nature of each subject’s preexisting 
conditions, including clinically significant signs and symptoms of the disease under treatment in 
the study.
After the ICF is signed, site personnel will record any change in the condition(s) and the 
occurrence and nature of any AEs.  All AEs related to protocol procedures are reported to Lilly 
or designee.
In addition, all AEs occurring after the subject receives the first dose of study treatment must be 
reported to Lilly or its designee via the eCRF.
Any clinically significant findings (vital sign measurements, laboratory measures, and treatment 
exposure) that result in a diagnosis should be reported to Lilly or its designee.
Investigators will be instructed to report to Lilly or its designee their assessment of the potential 
relatedness of each AE to protocol procedure, study treatment, and/or drug delivery system via 
eCRF.  
The investigator decides whether he or she interprets the observed AEs as either related to 
disease, to the study medication, study procedure, study device, or other concomitant treatment 
or pathologies.  To assess the relationship of the AE to study treatment, the following 
terminologies are defined:
Related:  a direct cause and effect relationship between the study treatment and the AE is 
likely
Possibly related:  a cause and effect relationship between the study treatment and the AE 
has not been demonstrated at this time and is not probable, but is also not impossible
Unrelated:  without question, the AE is definitely not associated with the study 
treatment.
As per Lilly’s standard operating procedures, all “related” and “possibly related” AEs and SAEs 
will be defined as related to study treatment.
If a subject’s dosage is reduced, or treatment is discontinued as a result of an AE, study site 
personnel must clearly report to Lilly or its designee via eCRF the circumstances and data 
leading to any such dosage reduction or discontinuation of treatment.
Serious Adverse Events
10.4.1.1.
Serious adverse event collection begins after the subject has signed informed consent and has 
received study treatment.  If a subject experiences an SAE after signing informed consent, but 
prior to receiving study treatment, the event will NOT be reported as serious unless the 
investigator feels the event may have been caused by a protocol procedure.

B5K-MC-IBHD Clinical Protocol
Page 52
LY041001
Planned surgeries should not be reported as SAEs unless the underlying medical condition has 
worsened during the course of the study.
Study site personnel must alert Lilly or its designee of any SAE within 24 hours of investigator 
awareness of the event via a Sponsor-approved method.  If alerts are issued via telephone, they 
are to be immediately followed with official notification on study-specific SAE forms.  This 
24-hour notification requirement refers to the initial SAE information and all follow-up SAE 
information.  
An SAE is any AE from this study that results in one of the following outcomes:

Death 

Severe hypoglycemia (as defined in Section 10.4.2)

Initial or prolonged inpatient hospitalization

A life-threatening experience (that is, 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 result in death, be life-threatening, or require 
hospitalization may be considered serious adverse drug events when, based upon appropriate 
medical judgment, they may jeopardize the subject and may require medical or surgical 
intervention to prevent one of the outcomes listed in this definition.
When a condition related to the U-500 OmniPod system necessitates medical or surgical 
intervention to preclude either permanent impairment of a body function or permanent damage to 
a body structure, the serious outcome of “required intervention” will be assigned.
Serious adverse events occurring up to and including the subject’s last study visit will be 
collected, regardless of the investigator’s opinion of causation, in the clinical data collection 
database and the pharmacovigilance system at the sponsor.
The investigator does not need to actively monitor subjects for AEs once the trial has ended, 
unless provided otherwise in the protocol.  However, if an investigator becomes aware of SAEs
occurring to a subject after the subject’s participation in the trial has ended, the investigator 
should report the SAEs to the Sponsor, regardless of the investigator’s opinion of causation; the 
SAEs will be entered in the pharmacovigilance system by the sponsor.
Information on SAEs expected in the study population independent of drug exposure and that 
will be assessed by the Sponsor in aggregate periodically during the course of the trial may be 
found in the USPI.
10.4.1.1.1.Suspected Unexpected Serious Adverse Reactions
Suspected unexpected serious adverse reactions (SUSARs) are serious events that are not listed 
in the USPI and that the investigator identifies as related to study treatment or procedure.  United 

B5K-MC-IBHD Clinical Protocol
Page 53
LY041001
States 21 CFR 312.32 and European Union Clinical Trial Directive 2001/20/EC, and the 
associated detailed guidance 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 guidance.
10.4.2. Hypoglycemia
As a secondary objective, the rate/incidence of hypoglycemia will be analyzed and compared 
between treatment groups.  Subjects are encouraged to perform SMBG whenever hypoglycemia 
may be suspected, either by symptoms experienced or perceived increased risk as related to 
dietary intake, physical activity, or inadvertent or atypical insulin dosing.  All subjects will be 
instructed to treat a SMBG ≤70 mg/dL as hypoglycemia by ingesting 15 gram of CHO (for 
example, 4 ounces of juice or 3 to 5 gram glucose tabs). All subjects will be advised to contact 
the site if they experience severe hypoglycemia or SMBG <50 mg/dL.
Hypoglycemia is defined as ≤70 mg/dL (Seaquist et al. 2013) and categorized as follows:

Documented hypoglycemia
o
Documented symptomatic – an event that: 
1. is accompanied by with signs/symptoms of hypoglycemia, and
2. is accompanied by a measured SMBG concentrations of ≤70 mg/dL.  
o
Asymptomatic hypoglycemia an event that:
1. is not accompanied with signs/symptoms of hypoglycemia, and
2. is accompanied with a measured SMBG concentration of ≤70 mg/dL.
o
Unspecified hypoglycemia an event during that:
1. no relative signs/symptoms of hypoglycemia are recorded, and
2. is accompanied with a measured SMBG concentration of ≤70 mg/dL. 

Severe hypoglycemia: An event accompanied by neuroglycopenic symptoms 
that result in cognitive impairment such that the patient requires assistance of 
another person to actively administer CHO, glucagon, or perform other 
resuscitative actions.  During these episodes, the patient has an altered mental 
status, and cannot assist in their care, is semiconscious or unconscious, or 
experienced coma with or without seizures, and may require parenteral therapy.  
Plasma glucose measurements may not be available during such an event, but 
neurological recovery attributable to the restoration of SMBG concentration to 
normal is considered sufficient evidence that the event was induced by a low 
SMBG concentration (≤70 mg/dL).

Nocturnal hypoglycemia:  Any hypoglycemic event (documented hypoglycemia 
or severe hypoglycemia) that occurs between bedtime and waking. 

B5K-MC-IBHD Clinical Protocol
Page 54
LY041001
10.4.3. Body Weight
The scale should be zeroed out before the subject is weighed.  Subjects should remove their 
shoes and any additional layers of clothing (such as sweaters or coats) and empty their pockets 
before being weighed.  If possible, subjects should also be given the opportunity to empty 
bladder/bowel before being weighed.  The weight value should be recorded in the source 
documentation and the eCRF.
10.4.4. Other Safety Measures
Vital signs
10.4.4.1.
Blood pressure and pulse, as well as height and weight, will be measured and recorded at the 
indicated visits per the Study Schedule (Attachment 1).  Blood pressure will be measured using a 
standard blood pressure meter to obtain the systolic and diastolic pressures with the subject
sitting for at least 5 minutes prior to the measurement.
Physical Examinations
10.4.4.2.
Complete physical examinations will be performed at Visit 1 according to the Study Schedule 
(Attachment 1).
Electrocardiograms
10.4.4.3.
For each subject, 12-lead digital electrocardiograms (ECGs) will be performed locally at Visit 1 
according to the Study Schedule (Attachment 1).  Subjects must be supine for approximately 
5 to 10 minutes before ECG collection and remain supine but awake during ECG collection.  
The ECGs will 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 subject is still 
present, to determine whether the subject meets entry criteria at the relevant visit(s) and for 
immediate subject management, should any clinically relevant findings be identified.  
Investigators must document their review of ECG reports.
Clinical Laboratory Tests
10.4.4.4.
Clinical laboratory tests will be conducted at the indicated visits per the Study Schedule 
(Attachment 1) and Clinical Laboratory Tests (Attachment 2).
Concomitant Medications
10.4.4.5.
Concomitant medication usage will be assessed at office visits, per the Study Schedule 
(Attachment 1).  Concomitant medications allowed in this study are discussed in Section 9.11
and Table IBHD.9.7.
Functionality and Safe Use of OmniPod U-500 System
10.4.4.6.
The functionality issues, hazards alarms, and safe use of the OmniPod U-500 system will be 
evaluated at study visits and/or by an assessment of device complaint data. 
10.4.5. Safety Monitoring
The Lilly CRP or CRS will monitor safety data throughout the course of the study.

B5K-MC-IBHD Clinical Protocol
Page 55
LY041001
Lilly will review SAEs within timeframes mandated by company procedures.  The Lilly 
CRP/CRS will, as is appropriate, consult with the functionally independent Global Patient Safety 
therapeutic area physician or clinical scientist, and periodically review:

Trends in safety data

Laboratory analytes

AEs

Product complaints
If a study subject experiences elevated ALT or AST ≥3X ULN, elevated total bilirubin ≥2X 
ULN, or alkaline phosphatase ≥2X 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 subject safety and comply with regulatory 
guidance, the investigator is to consult with the Lilly designated medical monitor regarding 
collection of specific recommended clinical information and follow-up laboratory tests.
10.4.6. Complaint Handling
Lilly collects product complaints on study treatment 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.
Complaints related to unblinded drug delivery systems (with exception of U-500 OmniPod 
system) are reported directly to the manufacturers of those drugs/devices in accordance with the 
package insert.
The investigator or his/her designee is responsible for handling the following aspects of the 
product complaint process in accordance with the instructions provided for this study:

Recording a complete description of the product complaint reported and any 
associated AEs using the study-specific complaint forms provided for this 
purpose.

The completed product complaint form must be faxed within 24 hours to Lilly or 
its designee.
If the investigator is asked to return the product for investigation, he/she will return a copy of the 
product complaint form with the product.
10.5. Sample Collection and Testing
The Study Schedule (Attachment 1) lists the schedule for sample collections in this study.  The 
Clinical Laboratory Tests (Attachment 2) lists the laboratory tests that will be performed for this 
study.  

B5K-MC-IBHD Clinical Protocol
Page 56
LY041001
10.5.1. Samples for Study Qualification and Health Monitoring
Standard laboratory tests including chemistry, hematology, and urinalysis panels will be 
performed. The Clinical Laboratory Tests (Attachment 2) lists the specific tests that will be 
performed for this study.  Clinical laboratory tests will be analyzed by a central laboratory 
selected by Lilly.  
Blood and urine samples will be collected per standard procedures at the times specified in the 
Study Schedule (Attachment 1).  Blood will be collected by venipuncture.
Investigators must document their review of each laboratory safety report.
Samples collected for specified laboratory tests will be destroyed within 60 days of receipt of 
confirmed test results.  Tests are run and confirmed promptly whenever scientifically 
appropriate.  When scientific circumstances warrant, however, it is acceptable to retain samples 
to batch the tests run, or to retain the samples until the end of the study to confirm that the results 
are valid.  Certain samples may be retained for a longer period, if necessary, to comply with 
applicable laws, regulations, or laboratory certification standards.
10.5.2. Pharmacogenetic Samples for Biomarker Research
Samples will be stored and analysis may be performed on genetic variants thought to play a role 
in insulin sensitivity, efficacy, beta cell function, hypoglycemia risk, and TDD requirements 
(Section 6.3) including, but not limited to, Insulin receptor, Insulin like Growth Factor-1, 
Melatonin Receptor 1B1, adiponectin and transcription factor 7-like 2, Phosphoinositide-3-
Kinase, Regulatory Subunit 1 and B-Cell CLL/Lymphoma 11A to evaluate their association with 
observed clinical outcomes to U-500R (a one-time collection, as noted in the Study Schedule
[Attachment 1]).
There is growing evidence that genetic variation may impact a subject’s response to therapy.  
Variable response to therapy may be due to genetic determinants that impact drug absorption, 
distribution, metabolism, and excretion, the mechanism of action of the drug, the disease 
etiology and/or the molecular subtype of the disease being treated.  Therefore, where local 
regulations and ERBs allow, a blood sample will be collected for pharmacogenetic analysis.  
In the event of an unexpected AE or the observation of unusual response, the pharmacogenetic 
samples may be genotyped and analysis may be performed to evaluate a genetic association with 
response to U-500R.  These investigations may be limited to a focused candidate gene study or, 
if appropriate, genome-wide analysis may be performed to identify regions of the genome 
associated with the variability observed in drug response.  The pharmacogenetic samples will 
only be used for investigations related to disease and drug or class of drugs under study in the 
context of this clinical program.  They will not be used for broad exploratory unspecified disease 
or population genetic analysis.
The samples will be coded with the subject number and stored for up to a maximum 15 years 
after the last subject visit for the study at a facility selected by the Sponsor.  The samples and any 
data generated from them can only be linked back to the subject by investigator site personnel.  
The duration allows the Sponsor to respond to regulatory requests related to study treatment.

B5K-MC-IBHD Clinical Protocol
Page 57
LY041001
Pharmacogenetic data will not be provided to the investigators nor will it be shared with patients 
in the trial. Samples will be destroyed according to a process consistent with local regulation.
10.5.3. Nonpharmacogenetic Biomarker Stored Samples
Collection of samples for nonpharmacogenetic biomarker research is a required part of this 
study.  Urine and blood (serum and plasma) samples will be collected as specified in the Study 
Schedule (Attachment 1).
Samples may be used for research to understand the pathophysiology of T2DM or its 
complications, the mechanism of action, efficacy, and/or adverse effects related to U-500R.  In 
addition, samples may be used to develop research methods and/or validate diagnostic tools or 
assays.  Nonpharmacogenetic biomarker data from stored samples will not be provided to the 
investigators nor will it be shared with patients in the trial.
Samples will be identified by the subject number (coded) and stored for up for a maximum of 
15 years after the last subject visit for the study at a facility selected by the Sponsor.
10.6. Appropriateness of Measurements
All efficacy and safety assessments included in this study are generally regarded as reliable and 
accurate with respect to management of T2DM.

Data Quality Assurance
To ensure accurate, complete, and reliable data, Lilly or its representatives will do the following:

Provide instructional material to the study sites, as appropriate.

Provide start-up training to instruct the investigators and study coordinators.  This 
training will give instruction on the protocol, the completion of the eCRFs, and 
study procedures.

Make periodic visits to the study site.

Be available for consultation and stay in contact with the study site personnel by 
mail, telephone, and/or fax.

Review and evaluate eCRF data and use standard computer edits to detect errors 
in data collection.

Conduct a quality review of the database.
To reduce missing data in the study, subjects who are discontinued from study treatment before 
study completion will be encouraged to remain in the study for continued safety monitoring (see 
Section 8.3.2).  In addition, study site investigators will be trained on the importance of complete 
data collection.
Lilly or its representatives will periodically check a sample of the subject data recorded against 
source documents at the study site.  The study may be audited by Lilly or its representatives, 
and/or regulatory agencies at any time.  Investigators will be given notice before an audit occurs.
To ensure the safety of participants in the study, and to ensure accurate, complete, and reliable 
data, the investigator will keep records of laboratory tests, clinical notes, and subject medical 
records in the subject files as original source documents for the study.  If requested, the 
investigator will provide the Sponsor, applicable regulatory agencies, and applicable ERBs with 
direct access to original source documents.
11.1. Data Capture System
An electronic data capture system will be used in this study.  The site maintains a separate source 
for the data entered by the site into the Sponsor-provided electronic data capture system.  Case
report form data will be encoded and stored in a clinical trial database.  Data managed by a 
central vendor, such as laboratory test data, will be stored electronically in the central vendor’s 
database system.  Data will subsequently be transferred from the central vendor to the Lilly 
generic labs system.
Any data for which paper documentation provided by the subject will serve as the source 
document will be identified and documented by each site in that site’s study file.  Paper 
documentation provided by the subject may include, for example, a paper diary to collect PRO 
measures (for example, a rating scale), a daily dosing schedule, or an event diary.

B5K-MC-IBHD Clinical Protocol

Sample Size and Statistical Methods
12.1. Determination of Sample Size
Approximately 320 subjects requiring high-dose insulin without use of GLP-1 receptor agonists 
or SGLT2 inhibitors (Group A) and approximately 64 to 96 additional subjects with use of GLP-
1 receptor agonists or SGLT2 inhibitors (Group B) will be randomized based on a 1:1 ratio to 
two treatment arms.  Approximately 240 (Group A) and 48 to 72 (Group B) subjects are 
expected to complete the 26-week treatment period (assuming a 25% dropout rate).
The sample size was calculated based on the first primary objective for subjects without use of 
GLP-1 receptor agonists or SGLT2 inhibitors (Group A).  The 240 completers will provide 80%
statistical power to demonstrate the noninferiority (NIM is 0.4%; SD=1.1%) of U-500R insulin 
CSII versus U-500R MDI in change in HbA1c at 26 weeks at 2-sided alpha = 0.05. 
12.2. Statistical and Analytical Plans
12.2.1. General Considerations
Statistical analysis of this study will be the responsibility of Eli Lilly and Company or its 
designee.
Unless otherwise specified, both safety and efficacy analyses will be conducted on the ARS, 
including those rescued.  This set includes all randomized patients and is defined based on the 
intention-to-treat (ITT) principle.  Sensitivity analysis may be done for the Full Analysis Set 
(FAS) that includes ARS subjects who received at least 1 dose of the U-500R via the 
administration method to which they were assigned.
In general, missing data will not be imputed, unless otherwise specified, eg, where the LOCF 
method is mentioned.
Baseline will be the last value obtained at or prior to the randomization, unless otherwise stated. 
Separate listings for safety data will also be done for those patients who discontinue study 
treatment but still remain in the study for safety monitoring purpose. These listings will contain 
data after the patients discontinue the study treatment.
All tests of treatment effects will be conducted at a 2-sided alpha level of 0.05, unless otherwise 
stated.
Changes to the data analysis methods described in the protocol will require an amendment only
if it changes a principal feature of the protocol.  Any other changes to the data analysis methods 
described in the protocol, and the justifications, will be described in the clinical study report.  
Additional exploratory analyses of the data will be conducted as deemed appropriate.
12.2.2. Adjustment for Multiplicity
This section explains the graphical approach in detail and illustrates how the graphical approach 
works in practice.  As discussed in Bretz et al. 2009, this testing approach controls the 

B5K-MC-IBHD Clinical Protocol

LY041001
family-wise type I error rate at alpha=0.05.  More details of this method will be documented in 
the SAP.
Figure IBHD.12.1 illustrates the graphical approach to adjust multiplicity for the primary and 
key secondary objectives.  In Figure IBHD.12.1 and for the explanations of the scenarios, the 
alternative hypotheses H1 through H10 are defined as follows:
H1: CSII is noninferior to MDI in change in HbA1c using a NIM of 0.4%.
Key Secondary Objectives:
H2: CSII is superior to MDI in change in FPG.
H3: CSII is superior to MDI in proportions of subjects achieving HbA1c targets/values 
<7.0%.
H4: CSII is superior to MDI in change in HbA1c. 
H5: CSII is superior to MDI in proportions of subjects achieving HbA1c targets/values 
<7.5%.
H6 through H10 are the same as H1 through H5 except that they are combined for the total study 
population Group A (without use of GLP-1 receptor agonists or SGLT2 inhibitors) and Group B
(those who use GLP-1 receptor agonists or SGLT2 inhibitors). 
As shown by the Figure IBHD.12.1, the graphical approach begins with testing the noninferiority 
for the primary objective at alpha=0.05.  The numbers (weights) on the arrows depict the 
proportion of alpha which is propagated to the next test if a null hypothesis is rejected.  At each 
step, all hypotheses are tested based on the current alpha assigned to them by the approach.  If,
and only if one of the null hypotheses is rejected, then the alpha flows based on the graph, and 
the weights are updated based on the preset algorithms and rules as described in Bretz et al.
2009.

Figure IBHD.12.1.
Graphical approach to adjust multiplicity.
One of the possible scenarios for the graphical approach is given below (step by step) for 
illustration only: 

The null hypothesis for H1 is rejected at alpha=0.05, so H2 will be tested at 
alpha=0.01 and H3 will be tested at alpha=0.04.

The null hypothesis for H3 is rejected at alpha=0.04, so based on the graph 
(Figure IBHD.12.1), 99% of the alpha (0.0396) from H3 will flow to H2 and 1%
of the alpha (0.0004) from H3 will flow to H4.  Therefore, H2 will be tested at 
alpha=0.01+0.0396=0.0496 and H4 will be tested at alpha=0+0.0004=0.0004.  

The null hypothesis for H2 is rejected at alpha=0.0496, so based on the updated
graph and weights, 100% of its alpha will flow to H4 and H4 will be tested at 
alpha=0.0004+0.0496=0.05.

The null hypothesis for H4 cannot be rejected at alpha=0.05, so the graphical approach 
stops here.

12.2.3. Subject Disposition
All subjects who discontinue from the study will be identified, and the extent of their 
participation in the study (discontinuation visit; whether remain in the study after discontinuation 
of study treatment for safety monitoring) will be reported.  If known, a reason for their 
discontinuation will be given.  The primary reasons for discontinuation will be listed for all 
subjects who have entered the study (signed informed consent) and will be summarized for the 
lead-in period.  Reasons for discontinuation of study treatment and study will also be 
summarized by treatment for the ARS, by visit and for overall study.  All of the summaries will 
be broken down by “discontinue study treatment but remain for safety monitoring” and 
“discontinue both study treatment and the study”. The treatment comparison will be based on 
Fisher’s exact test or Pearson’s chi-square test, as appropriate.  
12.2.4. Subject Characteristics
The subject characteristics and demographic variables will be recorded at Screening (Visit 1; 
Week -3) and will be listed and summarized by treatments.  The summaries will include 
descriptive statistics such as:  mean, SD, sample size, median, minimum, and maximum for 
continuous variables; and frequency, percentage, and number of subjects for categorical 
variables.  The treatment groups will be compared using an analysis of variance model for 
continuous measurements and Fisher’s exact test for categorical measurements.  In addition, 
these analyses will be conducted for baseline hypoglycemic episodes collected from Visit 2 to 
Visit 4.
12.2.5. Concomitant Therapy
Frequencies and percentages of concomitant medication used prior to and after randomization 
(by visit), will be summarized by treatments.  Antihyperglycemic agents will be summarized by 
treatment at entry, randomization, and the end of study.  AHA usage change and AHA mean 
daily-dose change from baseline to the end of study will be summarized by treatment.  Treatment
comparisons will be conducted.  
12.2.6. Treatment Compliance
No specific study data will be collected for analysis for treatment compliance except as it is 
collected in Patient Reported Outcomes Questionnaires.
12.2.7. Primary Outcome and Methodology
The primary efficacy measure is change from baseline (last nonmissing value at or prior to the 
treatment starting at randomization) to the 26-week HbA1c value, which will be summarized and 
analyzed using a MMRM approach for the ARS.  The baseline is selected to be the last value on 
or prior to the randomization visit: Visit 4 (Week 0).  Neither LOCF method nor other 
imputation methods will be used for the outcome measures. However, LOCF method will be 
used for sensitivity analysis.  The MMRM model adjusts for missing data through an observed-
data-likelihood-based approach.  The model will include the following fixed effects:  treatment 
(U-500R CSII, U-500R MDI), weeks on treatment, the interaction between treatment and weeks, 

B5K-MC-IBHD Clinical Protocol
Page 64
LY041001
and the appropriate stratification factor (nonusers versus users of GLP-1 receptor agonists or
SGLT2 inhibitors and U-500R at entry versus other insulins).  The model will also include 
baseline HbA1c as a covariate.  An unstructured covariance matrix will be first modeled for the 
repeated measures of each subject.  If the analysis fails to converge, the following variance-
covariance matrix will be used (in order) until one converges:
1.
Heterogeneous compound symmetry;
2.
Compound symmetry;
3.
First-order autoregressive.
The test for the first primary objective of noninferiority will be performed at the 0.05 
significance level using the LS mean estimate of the difference in change in HbA1c between the 
two treatments at Week 26.  Noninferiority will be established if the upper limit of a 2-sided 95% 
confidence interval (CI) for the difference (U-500R CSII minus U-500R MDI) is below the NIM 
of 0.4%.
Using the LS mean estimate of the difference in change in HbA1c between the 2 treatments, 
superiority will be established if the upper limit of a two-sided 95% CI for the difference 
(U-500R CSII minus U-500R MDI) is below 0.
The following supportive and sensitivity analyses will also be conducted:

If the following sets are different from ARS, then similar MMRM analyses will be done 
for the FAS (subjects who were randomized and received at least 1 dose of the study 
insulin through the administration method they were assigned to), all completer set 
(subjects who complete the study), and the per-protocol population (subjects included in 
the ARS who have completed the study without significant protocol violations).

An “analysis of covariance” model with similar fixed effects as in the MMRM analysis
using LOCF method for the ARS.
12.2.8. Secondary Efficacy Analyses
Similar MMRM models for the ARS will be used to analyze the change from baseline for the 
following values at week 26:
1)
FPG (by laboratory measurement)
2)
7-point SMBG
3)
Total Daily Insulin dose (TDD)
Baseline values will be the last value obtained for each subject at or prior to the randomization 
visit: Visit 4, unless otherwise stated.  The MMRM model will include similar fixed effects as in 
the primary analysis, with the corresponding baseline measures included as a covariate.  The 
model specifications will be carefully adjusted as appropriate.

B5K-MC-IBHD Clinical Protocol
Page 65
LY041001
For the following values at week 26:

Proportions of subjects achieving HbA1c targets/values (≤6.5%; <7.0%; <7.5% and 
<8.0%). 

Proportions of subjects achieving HbA1c targets/values (≤6.5%; <7.0%; <7.5% and 
<8.0%) without documented symptomatic hypoglycemia (SMBG <50 mg/dL).
Treatment comparisons will be analyzed using a repeated-measure logistic regression model 
including subject to account for the repeated measurements and similar fixed effects as in the 
above MMRM models.  The proportion of subjects achieving HbA1c targets with no 
documented symptomatic hypoglycemia (from baseline to the corresponding visit) will be 
analyzed using a similar repeated-measure logistic regression model including the baseline 
documented symptomatic hypoglycemia event rate as a covariate. 
12.2.9. Exploratory Analyses
Patient Reported Outcomes Analyses
12.2.9.1.
As an exploratory objective, the TRIM-D and TRIM-DD measures will be used to compare the 
change in diabetes treatment and diabetes treatment device on patient’s functioning, well-being,
and quality-of-life outcomes from baseline to the 26-week values between treatment groups.  
12.2.9.1.1.TRIM-D and TRIM-DD
The TRIM-D and TRIM-DD will be administered at Visit 4 (Week 0, prior to randomization), at 
Visit 13 (Week 14) and at Visit 17 (Week 26) or ET if subjects do not complete the full 26 weeks 
of the study.
Summaries of the domain and overall scores will include sample size, mean, SD, median, 
minimum, maximum, LS mean and standard error (SE) of LS mean.  The changes from baseline 
in domain scores and total scores of TRIM-D and TRIM-DD will be analyzed using MMRM 
model (similar to the primary/secondary analyses). For change from baseline, LS means and SE 
of LS means will be reported by treatment group.  For treatment difference of change, LS means, 
SE of LS means, 95% CI, and p-value will be reported.
OmniPod U-500 System Exit Questionnaire
12.2.9.2.
An OmniPod U-500 System Exit Questionnaire will be administered to CSII subjects at Visit 17
(Week 26) or at ET if subjects do not complete the full 26 weeks of the study.
Descriptive statistics will be provided to summarize the results from the U-500 System Exit 
Questionnaire. 
Functionality and Safe Use of the OmniPod U-500 System
12.2.9.3.
The functionality and safe use of the OmniPod U-500 system will be evaluated by an assessment 
of device complaint data and subject reported hazard alarms and clinically relevant 
hyperglycemia possibly related to site occlusion.  Lilly should be contacted for CSII device 
complaints and will provide the data to be listed.  The reported hazard alarms as well as the 
“Infusion Site Change” from the diary will be listed also.

12.2.10.
Safety Analyses
As stated in Section 6.2, all of the secondary objectives will be analyzed for Group A and for the 
total study population (Groups A and B combined).  Safety measures will include hypoglycemic 
events, body weight, AEs and TEAEs, vital signs (systolic and diastolic blood pressures and 
pulse), study treatment exposure, and laboratory measures.  As stated in Section 12.2.1, all safety 
measures will be summarized for ARS by treatment and by visit for the 26-week treatment 
period. Safety measures will also be listed for those patients who discontinue study treatment 
but still remain in the study for safety monitoring purpose. These listings will contain data after 
the patients discontinue the study treatment. For treatment comparisons of frequency and 
proportion of event variables (such as AEs and hypoglycemia events), the conventional Fisher’s 
exact test or Pearson’s chi-square test are appropriate to use.  Further details of analyses will be 
provided in the SAP.
Hypoglycemia
12.2.10.1.
The rate per 30 days calculated between 2 visits is defined as the total number of episodes for all 
subjects between the visits divided by the total actual number of exposure days between the 
visits, and then multiplied by 30 days.  A similar definition will be used to calculate the rate per 
subject per 365 days (year).
For documented (documented symptomatic, asymptomatic and unspecified), severe and 
nocturnal hypoglycemic episodes, the following analyses will be conducted.  The incidence and 
percentage of subjects with at least 1 hypoglycemic event will be analyzed using Fisher’s exact 
test or Pearson’s chi-square test, as appropriate.  The rate of hypoglycemic events per 30 days
and per 365 days will be analyzed using a repeated-measure negative binomial regression model 
with similar fixed effects as in the primary analysis model.  Baseline hypoglycemic event rate for
the corresponding category of the dependent hypoglycemia variable will be included as a 
covariate, as well as the stratification factors.  
Body Weight
12.2.10.2.
Baseline values used for the weight analysis will be obtained for each subject at or prior to 
randomization. The body weight change will be analyzed by MMRM models similar to that 
which will be used in the primary analysis for the ARS population.  The MMRM model will 
include similar fixed and random effects, as in the primary analysis, with the corresponding 
baseline measures included as a covariate.  The model specifications will be adjusted as 
appropriate.
Treatment-Emergent Adverse Events and Serious Adverse Events
12.2.10.3.
Adverse events will be listed by subject, system organ class, preferred term, severity, and 
relationship to the study disease, drug, device, or procedure.  Adverse events will be summarized 
as TEAEs during treatment period (defined as events that are newly reported after randomization 
Visit 4 or reported to be worsened in severity from randomization Visit 4) for ARS by treatment
and visit. Similar listings will be done for subjects who discontinued study treatment but still 
remain in the study for safety monitoring purpose. These listings will contain data after the 
patients discontinue the study treatment.

B5K-MC-IBHD Clinical Protocol
Page 67
LY041001
The frequency and proportion of subjects experiencing at least 1 of each reported TEAE will be 
summarized by system organ class, preferred term, and treatment group for treatment period.  
The frequency and proportion comparisons will be analyzed using Fisher’s exact test or 
Pearson’s chi-square test, as appropriate.  The frequency and proportion of subjects experiencing
at least 1 of each reported TEAE that are assessed as possibly related to the study disease, drug, 
device, or procedures will also be summarized. 
All SAEs (including severe hypoglycemic events) will be listed by subject with similar 
information as the AE listing.  If a sufficient number of SAEs are reported, then a frequency and 
proportion summary, similar to the summary for TEAEs, will be included for the ARS.  
Discontinuations due to TEAEs and SAEs will be listed separately, by subject (including 
information about whether they discontinue only the study treatment or study treatment and the 
study), and summarized (if a sufficient number of events are reported) by treatment. All of the 
summaries will be broken down by “discontinue study treatment but remain for safety 
monitoring” and “discontinue both study treatment and the study.”
Vital Signs
12.2.10.4.
Systolic and diastolic blood pressures and pulse will be summarized by visit and additionally for 
endpoints (LOCF).  Additionally, change from baseline to the last visit of each period for actual 
value and endpoint (LOCF) will be summarized.
Study Treatment Exposure
12.2.10.5.
Exposure to each treatment will be calculated for each subject and summarized by treatment.  
Total subject-years will be included in the summaries.
Laboratory Measures
12.2.10.6.
As applicable per protocol, measures within the following panels will be summarized at 
Screening (Visit 1), Visit 4 (Week 0), Visit 13 (Week 14), and Visit 17 (Week 26) or endpoint 
(LOCF):

Chemistry 

Hematology 

Lipids
Treatment-emergent high, low, and abnormal values will be summarized for each lab measure.
A treatment-emergent high value is defined as a value that was normal or low at baseline and 
subsequently found to be above the normal range at any post-baseline visit.  A treatment-
emergent low value is defined as a value that was normal or high at baseline and subsequently 
found to be below the normal range at any post-baseline visit.  A treatment-emergent abnormal 
value is defined as a value that was normal at baseline and subsequently found to be abnormal at 
any post-baseline visit.
12.2.11.
Safety Committee
Trial level safety reviews using selected blinded safety data will be conducted throughout the 
study by the study team.  

B5K-MC-IBHD Clinical Protocol
Page 68
LY041001
12.2.12.
Interim Analyses
A DMC (Data Monitoring Committee) will have access to unblinded data for their review(s).  
Only the DMC is authorized to evaluate unblinded interim safety analyses.  The DMC will be 
composed of individuals internal and external to Lilly who are not part of the study team and will 
monitor the safety of U-500R administered CSII or MDI and may recommend changes to the 
protocol, including termination.  Unblinding details are specified in the unblinding plan section 
of the SAP and/or DMC Charter.  The timing and frequency of these data reviews will be stated 
in the DMC charter.  In the event of any patient safety concerns, the DMC will communicate to
the study team so that the CRP/CRS can inform the investigator of appropriate action.  Study 
sites will receive information about interim results ONLY if they need to know for the safety of 
their subjects.
If an unplanned interim analysis is deemed necessary, the appropriate Lilly regulatory scientist
will be consulted to determine whether it is necessary to amend the protocol.

telephone; TRIM-D = treatment-related impact measure for diabetes; TRIM-DD = treatment-related impact measure for diabetes device; w = week.
a
Early termination visit only performed on subjects who did not complete the full 26 weeks of the study.
b
Prior to randomization at Visit 4, all subjects will be re-confirmed for inclusion criteria [1], [2], and [7] and exclusion criteria [18].
c
Central laboratory unless otherwise specified.  Laboratory tests may be performed at any time at the investigator’s discretion in the event of an adverse event.
d
Serum screening pregnancy test will be performed at Visit 1 for women of childbearing potential by a Lilly-designated central laboratory.  A urine pregnancy 
test may be repeated locally for any follow-up visits.
e
Hypoglycemic and AEs should be collected in the subject’s diary and will be discussed during telephone visits and at the next onsite visit for each subject 
unless a severe hypoglycemic event occurs (SAE that needs to be reported immediately).
f
Subjects will be instructed to record 7-point SMBG profiles on 2 nonconsecutive days (including a weekend day if possible) in the 2 weeks prior to Visits 4, 
13, and 17.
g
Health outcomes questionnaires will be administered prior to randomization during this office visit.
h
OmniPod U-500 System Exit Questionnaire will be administered to CSII subjects at ET if subjects terminate during treatment period.  
i
Subjects will be introduced to the basics of the OmniPod U-500 system at investigator site before beginning CSII treatment but will not be given the device.
j
Subjects will receive hands-on training of the OmniPod U-500 system at investigator site using study drug and will be given device to begin CSII treatment.
k
Study drug assessed and dispensed based on need and expiration.

Attachment 3.World Health Organization (WHO) 
Classification of Diabetes
Type 1 Diabetes Mellitus:  Type 1 diabetes mellitus is judged to be present when the classical 
symptoms of diabetes (thirst, polyuria, wasting and stupor, or coma) are associated with readily 
detectable concentrations of glucose and ketone bodies in the blood and urine.  Insulin treatment 
is necessary not only to control hyperglycemia but also to prevent spontaneous ketosis and death
(Alberti and Zimmet 1998).
Type 2 Diabetes Mellitus:  Type 2 diabetes mellitus, although often asymptomatic, may also 
present with classical hyperglycemic symptoms (thirst, polyuria, weight loss), but despite 
hyperglycemia, ketone bodies are present in only low concentrations in the blood and urine.  
Coma is rare in type 2 diabetes but may result from extreme hyperglycemia and hyperosmolarity; 
lactic acidosis or ketoacidosis can also occur in fulminating illness (for example, severe infection 
or mesenteric artery thrombosis) due to an acute increase in insulin requirements, but 
spontaneous ketosis does not occur.  Some patients with type 2 diabetes later progress to a state 
of absolute insulin deficiency (Alberti and Zimmet 1998).

Attachment 4.New York Heart Association (NYHA) Cardiac 
Disease Classifications
Functional Capacity (CCNYHA 1994):
Class I.
Patients with cardiac disease but without resulting limitation of physical activity.  Ordinary 
physical activity does not cause undue fatigue, palpitation, or dyspnea.
Class II.
Patients with cardiac disease resulting in slight limitation of physical activity.  They are 
comfortable at rest.  Ordinary physical activity results in fatigue, palpitation, dyspnea, or anginal 
pain.
Class III.
Patients with cardiac disease resulting in marked limitation of physical activity. They are 
comfortable at rest.  Less than ordinary activity causes fatigue, palpitation, or dyspnea.
Class IV.
Patients with cardiac disease resulting in inability to carry on any physical activity without 
discomfort.  Symptoms of heart failure at rest.  If any physical activity is undertaken, discomfort 
increases.
