Conditions: Type 1 Diabetes Mellitus Type 2 Diabetes Mellitus
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 69
Healthy volunteers: yes

Brief summary:
This is an active- and placebo-controlled, single-site, four-part trial of MK-1092 in healthy adult participants, in participants with type 1 diabetes mellitus (T1DM), and in participants with type 2 diabetes mellitus (T2DM). The primary hypothesis for this study is that at a dose with sufficient safety, the mean maximal glucose infusion rate (GIRmax) after single subcutaneous (SC) administration of MK-1092 in adult participants with T1DM is within an acceptable range. (Part 3)

Detailed description:
There will be 4 parts in this study. In Part 1, healthy adult participants will be randomized to receive blinded MK-1092 subcutaneously (SC) or glargine SC, as a single dose under the euglycemic clamp. Once a safe and tolerated dose that achieves GIRmax is identified in Part 1, Part 2 will start. In Part 2, 4 different healthy adult participants will be enrolled in a single panel and receive open-label MK-1092 SC as a single dose under the euglycemic clamp and also receive an intravenous infusion of Humalog®. In Part 3, adult participants with T1DM will be randomized to receive blinded MK-1092 SC or insulin glargine SC, as a single dose under the euglycemic clamp. Part 4 includes a 3-period (Periods 1, 2, and 3) design that will explore up to 3 single subcutaneous doses of MK-1092 or insulin glargine in participants with Type 2 diabetes mellitus.

Permitted within Protocol
Parameters;
Additional blood volume allowed for 
unscheduled pharmacokinetic (PK)/ 
pharmacodynamic 
(PD) 
or 
safety 
evaluations, 
including 
unscheduled 
Yellow Springs Instrument (YSI) blood 
glucose assessments during the clamp 
procedure, is increased from 50 mL to 
100 mL for subjects participating in 
Part 4 only.
This is completely offset by reductions 
in blood sampling for scheduled PK 
and PD evaluations in Part 4, Period 3.
Subjects in Part 4 participate in up to 3 
clamp procedures (1 per study period).  
Due to an unexpectedly high rate of 
GlucoScout sensor failure during Part 4, 
frequent unscheduled YSI blood glucose 
assessments, as allowed per protocol, 
have been required to maintain subject 
safety during the clamp.  Allowance of 
up to 100 mL of additional blood for 
safety/PK/PD assessments will include 
any 
unscheduled 
YSI 
glucose 
assessments 
during 
the 
subject’s 
participation in the study.

Description of Change (s)
Rationale
6.4;
12.3
Trial Flow Chart – Part 4;
Approximate Blood/Tissue 
Volumes Drawn/Collected 
by Trial Visit and by Sample 
Types;
The 
following 
time
points 
for 
MK-1092/ glargine PK evaluations 
were removed from the sampling 
scheme for Part 4 Period 3 only: 30 
min, 2 hr, and 96 hr post-dose. The 
revised sampling scheme is noted in 
footnote ‘m’ of the flowchart.
The following time points for NEFA, 
glycerol, C-peptide and ketone PD 
evaluations were removed from the 
sampling scheme for Part 4 Period 3 
only, as applicable:  2 hr, 6 hr, 12 hr, 
and 36 hr post-dose. The revised 
sampling scheme is noted in a new 
footnote ‘x’ of the flowchart.
The reduction in blood collections for 
PK/PD will offset the increase in 
allowable blood that may be collected 
for unscheduled safety assessments of up 
to 100 mL for subjects in Part 4.  The 
reduction in PK/PD sampling for this 
period will not significantly impact the 
ability to achieve the study objectives 
related to these end points.

2.0 TRIAL DESIGN
Trial Design
2.1
This is an active- and placebo-controlled, single-site, four-part trial of MK-1092 in healthy 
adult subjects, in subjects with type 1 diabetes mellitus (T1DM), and in subjects with type 2 
diabetes mellitus (T2DM) to be conducted in conformance with Good Clinical Practices.  
This is the first-in-human study for MK-1092, an insulin receptor partial agonist (IRPA), 
being developed as a basal insulin for patients with both type 1 (T1DM) and type 2 (T2DM) 
diabetes mellitus. All subjects will undergo a euglycemic clamp during and after 
subcutaneous (SC) administration of MK-1092, with or without infusion of lispro 
(Humalog®), or glargine.  The purpose of the study is to determine safety and tolerability of 
MK-1092 in healthy adult subjects, in adult subjects with T1DM, and in adult subjects with 
T2DM relative to glargine, to obtain pharmacokinetics (PK) of MK-1092 administered SC, 
and to determine the maximal glucose infusion rate (GIRmax) required to maintain target 
glucose levels in the euglycemic setting following SC dosing of MK-1092. 
There will be four parts in this study.  In Part 1, healthy adult subjects will be randomized to 
receive MK-1092 SC or glargine SC, as a single dose under the euglycemic clamp.  Subjects 
will be blinded in a double-dummy fashion, so that each subject will receive 
MK-1092/glargine and a matched placebo to the alternative active treatment. Part 1 will 
employ sentinel dosing.  The first three (3) subjects enrolled in each panel of Part 1 will be 
dosed individually with the trial treatment for which they were randomly allocated as per the 
computer generated allocation schedule (MK-1092 or glargine).  Subsequent subjects will not 
be dosed until at least 24 hours have elapsed after dosing of each of the first three subjects in 
each panel of Part 1. The starting dose in Part 1 Panel A is 4.0 nmol/kg. Dosing in all 
subsequent panels of Part 1 will commence upon review of the safety data from previous 
panels within Part 1 and determination of an acceptable safety profile to continue dose 
escalation. Up to 5 doses of MK-1092 will be administered in successive panels. The 
glargine dose will be the same in all panels of Part 1 and is expected to achieve GIR max

~2 mg/kg/min. The MK-1092 doses will include, and could potentially escalate beyond, the 
expected therapeutic insulin concentration range leading to a GIRmax ~1-2 mg/kg/min.  
Different subjects will participate in each panel (N=6/panel receiving MK-1092, N=2/panel 
receiving glargine). The objectives for this part will assess safety and tolerability of the SC 
injection, PK, and PD endpoints for MK-1092 and glargine in healthy adult subjects. Once a 
safe and tolerated dose that achieves GIRmax ~1-2 mg/kg/min is identified in Part 1, Part 2 
will start and subsequent panels in Part 1 will be paused.  Completion of Part 1 will be 
dependent upon the need for further dose exploration in healthy adult subjects.  
At the time of protocol amendment 02, a dose of 8.0 nmol/kg was safe, well-tolerated and 
had achieved GIRmax ~ 1-2 mg/kg/min. This dose was then tested in Part 2, and subsequent 
panels of healthy adult subjects were resumed. At the time of protocol amendment 03, the 
maximum dose tested to date is 64 nmol/kg in Part 1 Panel E. Data review for the 64 nmol/kg 
dose is ongoing. The preliminary review of Panel E indicates that the 64 nmol/kg dose, like 
the doses in Panels A-D (4 - 32 nmol/kg) has been safe and well-tolerated. 
In Part 2, four different healthy adult subjects than participated in Part 1 will be enrolled in a 
single panel and receive MK-1092 SC as a single dose under the euglycemic clamp; all 
subjects in this part will also receive an IV infusion of Humalog for three hours, starting 
~12 hr after SC administration of MK-1092, a time at which MK-1092 is anticipated to have 
a glycemic effect. The actual start time of Humalog infusion may be altered based on data 
from Part 1 and will be communicated to the site by a Protocol Clarification Letter prior to 
dosing. 
At the time of protocol amendment 02, the MK-1092 dose that was administered in Part 2 
Panel F had been selected following review of data from Part 1 as the dose that achieves a 
GIRmax of ~1-2 mg/kg/min (8.0 nmol/kg) and had been communicated to the site by a 
Protocol Clarification Letter prior to dosing. The purpose of Part 2 was to assure that a high 
dose of Humalog infusion could adequately reduce hyperglycemia in individuals who have 
received a therapeutic dose of MK-1092, as defined by achieving a GIRmax > 4 mg/kg/min 
during Humalog infusion. This part was open-label as all subjects were assigned to a single 
treatment by non-random assignment.  The objectives for this part are exploratory and will 
assess safety, tolerability, and adequate glycemic effect of IV Humalog after SC 
administration of MK-1092 in healthy adult subjects.
In Part 3, adult subjects with T1DM will be randomized to receive MK-1092 SC or glargine 
SC, as a single dose under the euglycemic clamp.  Subjects will be blinded in a double-
dummy fashion, so that each subject will receive MK-1092/glargine and a matched placebo
to the alternative active treatment. Dosing in the first panel of this part will use a SC dose no 
higher than one that has been determined to be safe, tolerated, and has achieved GIRmax of 
~1-2 mg/kg/min in healthy adult subjects in Part 1 and has been tested with Humalog 
infusion in Part 2 in healthy adult subjects. At the time of protocol amendment 03, a dose of 
8.0 nmol/kg had fulfilled these criteria and was safe and well-tolerated as the first dose in 
Panel G.  At the time of amendment 03, Part 3 Panel H (32 nmol/kg or glargine) was 
ongoing.

Dosing in all subsequent panels of Part 3 will commence upon review of the safety data from 
previous panels within Part 3 and determination of an acceptable safety profile to continue 
dose escalation.  Up to 3 doses of MK-1092 will be administered in successive panels. The 
glargine dose will be the same in all panels of Part 3 and is expected to achieve GIRmax
~2 mg/kg/min. The MK-1092 doses will include, and may escalate beyond, the expected 
therapeutic insulin concentration range for a GIRmax of ~1-2 mg/kg/min.  Doses in Part 3 will 
not exceed 64 nmol/kg SC, which is the highest planned dose in the clinical program. 
Different subjects will participate in each panel (N=6/panel receiving MK-1092, N=2/panel 
receiving glargine). The objectives for this part will assess safety and tolerability of the SC 
injection, PK, and PD endpoints for MK-1092 and glargine in adult subjects with T1DM.
Originally up to 4 doses of MK-1092 were planned for Part 3.  However, per PCL #10 (dated 
21-Mar-2018), Part 3 Panel I will not be conducted as it is anticipated that no more than 
3 doses in Part 3 will be needed to assess the safety, PK and PD in subjects with T1DM, 
following review of data from Part 1.  Additionally, an operational pause has been added 
between Panel H and Panel J in Part 3 only. The decision of whether to initiate Panel J will 
be made after thorough review of all available data from Panels G and H.   
In Part 4, adult subjects with T2DM will be randomized to receive MK-1092 SC or glargine 
SC, as a single dose under the euglycemic clamp. Adult subjects with T2DM may use insulin 
as part of the pre-study regimen (i.e., insulin-requiring T2DM) or may not use insulin as part 
of the pre-study regimen (i.e., non-insulin-requiring T2DM).  
In Part 4, subjects will be blinded in a double-dummy fashion, so that each subject will 
receive MK-1092/glargine and a matched placebo to the alternative active treatment. Dosing 
in the first period of this part will use a SC dose no higher than one that has been determined 
to be safe and tolerated in Part 1. At the time of protocol amendment 03, doses ≤64 nmol/kg 
have fulfilled these criteria. At the time of protocol amendment 04, a dose of 32 nmol/kg was
administered in Period 1 and a dose of 16 nmol/kg was administered in Period 2. Dosing in 
Period 3 of Part 4 will commence upon review of the safety data from previous periods
within Part 4 and determination of an acceptable safety profile to continue dose escalation.  
Up to 3 doses of MK-1092 will be administered in successive periods. The glargine dose will 
be the same in all periods of Part 4 and is expected to achieve GIRmax ~2 mg/kg/min. The 
MK-1092 doses will include, and may escalate beyond, the expected therapeutic insulin 
concentration range for a GIRmax of ~1-2 mg/kg/min.  Doses in Part 4 will not exceed 
64 nmol/kg SC, which is the highest planned dose in the clinical program. Unlike in Parts 1-
3, in Part 4 the same subjects will participate in each period (N=6 receiving MK-1092, N=3
receiving glargine). Subjects in Part 4 who are randomized to MK-1092 in Period 1 will 
receive MK-1092 in the subsequent periods, and subjects in Part 4 who are randomized to 
glargine in Period 1 will receive glargine in the subsequent periods. All subjects will 
complete dosing in Period 1 prior to the start of Period 2, and all subjects will complete 
dosing in Period 2 prior to the start of Period 3. In addition, determination of an acceptable 
safety profile in Period 1 will be required prior to starting Period 2 and an acceptable safety 
profile in Period 2 will be required prior to starting Period 3.  At least 7 days will occur 
between dose administrations in Part 4 to allow for washout. Furthermore, an operational 
pause will be implemented between Period 2 and Period 3 in Part 4 only to allow sufficient 
time for analysis of data collected in prior periods of Part 4 and/or panels of Parts 1 and 3 to

inform on dose decisions related to Period 3. The objectives for this part will assess safety 
and tolerability of the SC injection, PK, and PD endpoints for MK-1092 and glargine in adult 
subjects with T2DM.
Activities prior to and following the euglycemic clamp will differ for healthy adult subjects 
and for adult subjects with T1DM or T2DM. Healthy adult subjects (Part 1 and 2) will be 
admitted to the clinical research unit (CRU) on Day -1 and will fast for at least 8 h prior to 
the start of the euglycemic clamp and for the duration of the clamp. Healthy adult subjects 
will be discharged approximately 48 hrs after the start of the euglycemic clamp. 
Adult subjects with T1DM (Part 3) will be admitted to the CRU on Day -4, placed on 
continuous glucose monitoring (CGM), and started on a SC insulin pump to maintain 
glycemic control with an appropriate regimen of basal and bolus insulin during washout of 
pre-study insulin therapy. 
Adult subjects with T2DM (Part 4) will be admitted to the CRU on Day -4 of each period and 
placed on CGM. For all subjects with insulin-requiring T2DM, a SC insulin pump will be 
started to maintain glycemic control with an appropriate regimen of basal and bolus insulin. 
Subjects with non-insulin-requiring T2DM will not be placed on SC insulin pump unless the 
investigator determines this to be necessary to maintain glycemic control during the 
admission. 
Subjects who are already using a SC insulin pump for treatment of T1DM or T2DM may 
continue to use their own SC pump during the study at the discretion of the investigator; 
however the investigator may alter the basal and bolus settings or require the use of a site-
provided SC insulin pump based on medical judgment.  The insulin pump (if required) and 
CGM may remain in place until discharge or be removed based on the clinical judgement and 
discretion of the investigator. Insulin, if required, will be administered via the insulin pump 
throughout the trial, except during the clamp, according to standard clinical practice and at 
the discretion of the investigator. Subjects will have glucose assessments by fingerstick 
and/or CGM before meals, prior to bedtime, at least once overnight, and as needed per the 
subject and/or the investigator.  
In the evening on Day -1 adult subjects with T1DM and T2DM will begin a fast lasting at 
least 8 hours prior to the start of a euglycemic clamp.  During the fast, the basal insulin rate 
on SC pump (if active) will be suspended, and subjects will receive IV insulin and IV 
dextrose, as needed, to set blood glucose levels at ~100 mg/dL prior to dosing and clamp 
initiation. After dosing, the insulin infusion will be weaned as appropriate to maintain 
glucose concentrations at ~100 mg/dL. Once the insulin infusion is weaned off, a variable 
rate glucose infusion will be initiated and titrated to maintain blood glucose close to 
target. Subjects will remain fasted for the duration of the clamp. After completion of the 
euglycemic clamp, adult subjects with T1DM and T2DM will eat and resume their pre-study 
anti-diabetic regimen; however, they will continue to wear the CGM and use the insulin 
pump as needed until glycemic control has been re-established using the pre-study therapy.  
Subjects will be discharged from the site ~48 hours after the start of the clamp. The time of 
discharge may be dependent upon glycemic control being re-established after the euglycemic 
clamp and can be lengthened based on investigator discretion.

Specific procedures to be performed during the trial, as well as their prescribed times and 
associated visit windows, are outlined in the Trial Flow Chart - Section 6.0. Details of each 
procedure are provided in Section 7.0 – Trial Procedures.
Because this is a Phase I assessment of MK-1092 in humans, the pharmacokinetic, 
pharmacodynamic and safety profiles of the compound are still being elucidated. This 
protocol is therefore written with some flexibility to accommodate the inherent dynamic 
nature of Phase I clinical trials. Please refer to Section 7.1.5 – Visit Requirements for 
examples of modifications permitted within the protocol parameters.

b In Part 1, healthy adult subjects will be randomized to receive MK-1092 or glargine within each panel, with two 
subjects receiving glargine and six receiving MK-1092 according to a computer-generated allocation schedule. In 
addition to MK-1092 or glargine, subjects will also receive placebo (i.e., subjects receiving MK-1092 will also receive 
placebo matched to glargine, and subjects receiving glargine will also receive placebo matched to MK-1092).
Approximate injection volumes for doses of MK-1092 are: 2.4 µL/kg for 4.0 nmol/kg, 4.7 µL/kg for 8.0 nmol/kg, 9.4 
µL/kg for 16 nmol/kg, 19 µL/kg for 32 nmol/kg, 38 µL/kg for 64 nmol/kg.
c Unit conversions for glargine dosing: 3.0 nmol/kg = 0.5 U/kg. Injection volume for glargine 3.0 nmol/kg = 5 µL/kg.  
d In Part 2, four healthy adult subjects will receive MK-1092 within a single panel. The dose of MK-1092 in Part 2 is the 
SC dose that leads to a GIRmax of ~1-2 mg/kg/min, based on the results of Part 1, and will not exceed 64 nmol/kg.
e Unit conversions for Humalog dosing: 1.2 nmol/kg = 0.2 U/kg
f
In Part 3, adult subjects with type 1 diabetes mellitus will be randomized to receive MK-1092 or glargine within each 
panel, with two subjects receiving glargine and six receiving MK-1092 according to a computer-generated allocation 
schedule.  In Part 4, adult subjects with type 2 diabetes mellitus will be randomized to receive MK-1092 or glargine 
within each period, with the same three subjects receiving glargine in each period and the same six subjects receiving 
MK-1092 in each period according to a computer-generated allocation schedule. In addition to MK-1092 or glargine, 
subjects in Parts 3 and 4 will also receive placebo (i.e., subjects receiving MK-1092 will also receive placebo matched 
to glargine, and subjects receiving glargine will also receive placebo matched to MK-1092). The dose of MK-1092 in 
Part 3 Panel G (8 nmol/kg) is no higher than the SC dose that leads to a GIRmax of ~1-2 mg/kg/min in healthy adult 
subjects, based on the results of Part 1, and has been tested in healthy adult subjects with Humalog infusion in Part 2. 
The dose of MK-1092 in Part 4 Period 1 (32 nmol/kg) is no higher than one that has been determined to be safe and 
tolerated in Part 1. The maximum dose tested in Part 3 and Part 4 will not exceed 64 nmol/kg.

4.1.1
Diabetes mellitus (Type 1 and Type 2; T1DM, T2DM) is a global public health issue 
believed to affect over 400 million individuals worldwide in 2015, and is estimated to affect 
almost 650 million by 2040 [1].  Currently nearly 10% of the U.S. population is directly 
affected by the disease, and by 2050 it is estimated that 1 in 3 American adults will have 
diabetes [2].  According to CDC statistics, 14% of all patients with diabetes in the U.S. are 
on insulin alone, and another 13% are on a combination of insulin and oral therapy [2].  
Basal insulin, which is intended to maintain normal glucose levels during fasting, is the most 
commonly used form of insulin by patients with T2DM and is used by all patients with 
T1DM.  
Although insulin has been a mainstay of diabetes therapy for decades, exogenously 
administered insulin poses short-term risks and long-term drawbacks.  Excessive basal 
insulin leads to hypoglycemia, followed by several days of dose adjustment to achieve a new 
steady-state response.  Practitioners and patients thus often settle at moderate under-dosing of 
basal insulin and/or preemptive ingestion of carbohydrates, such as snacking before exercise 
or bedtime, to mitigate the risk for hypoglycemia associated with basal insulin. However, 
these strategies occur at the expense of not achieving target glycemic levels and thereby 
increasing the risk of long term complications of diabetes.
The goal of the Insulin Receptor Partial Agonist (IRPA) program is to develop a novel, once-
daily SC basal insulin with a wide therapeutic index (TI), permitting more aggressive 
treatment to the glycemic target with reduced risk of hypoglycemia.  The improved TI of an 
IRPA would significantly reduce the risk of hypoglycemia relative to available basal insulins, 
thus allowing more confidence for practitioners and patients to dose titrate IRPA to attain 
target goals for control of fasting glucose.
MK-1092 lowers glucose levels effectively but with a flatter dose response curve, an 
attenuated maximal effect, and extended duration of action in diabetic animal models relative 
to comparator insulins.
This study will be the first introduction of MK-1092 into human subjects, and will evaluate 
the safety, tolerability, PK and PD of MK-1092 in healthy adult subjects, adult subjects with 
T1DM, and adult subjects with T2DM.
Ongoing Clinical Trials

Preliminary Safety and Tolerability
To date, single subcutaneous doses of MK-1092 up to 64 nmol/kg have been evaluated in 
Part 1 (healthy adult subjects: Panels A [4.0 nmol/kg], B [8.0 nmol/kg], C [16 nmol/kg], D

[32 nmol/kg], and E [64 nmol/kg]); a dose of 8.0 nmol/kg has been evaluated during co-
administration with IV Humalog in Part 2 (healthy adult subjects); doses of 8.0 nmol/kg 
(Panel G) and 32 nmol/kg (Panel H) have been evaluated in Part 3 (subjects with T1DM), 
and doses of 32 nmol/kg (Period 1) and 16 nmol/kg (Period 2) have been evaluated in Part 4 
(subjects with T2DM). 
All doses have been safe and well-tolerated. There have been no serious adverse events and 
no discontinuations due to treatment-emergent adverse events. All adverse events have been 
mild or moderate and have resolved spontaneously.  
There have been no clinically significant changes in vital signs, laboratory parameters, or 
ECG findings. In Part 1 Panel B (8.0 nmol/kg), three different subjects experienced a mild 
and transient injection site reaction (injection site pain, injection site pain, injection site 
tenderness, respectively). In Part 1 Panel C (16 nmol/kg), three different subjects experienced 
a mild and transient injection site reaction (injection site pain, injection site pain, injection 
site burning, respectively). In Part 1 Panel E (64 nmol/kg), one subject experienced a mild 
and transient injection site soreness. In Part 3 Panel H (32 nmol/kg), one subject experienced 
a mild and transient injection site tenderness. In Part 4 Period 1 (32 nmol/kg), one subject 
experienced mild and transient pain at the injection site and another subject experienced an 
upper chest rash due to ECG leads. None of these events were evaluated as being an event of 
clinical interest (ECI). In Part 3 Panel G (8 nmol/kg), one subject experienced a mild and 
transient injection site erythema that was reported to the Sponsor as an ECI as well as a 
separate experience of transient erythema to ECG leads.  One other subject in Part 2 Panel F 
reported an ECI of dermatitis that was deemed unrelated to the study drug by the 
investigator. No injection site reactions were reported in other panels, including Part 1 Panel 
A (4 nmol/kg) and Panel D (32 nmol/kg). Treatment allocation (MK-1092 vs glargine) for 
Part 1, Part 3, and Part 4 remains blinded.

In Part 1, a dose of 8.0 nmol/kg was safe, well-tolerated, and achieved GIRmax of 
~1-2 mg/kg/min in healthy adult subjects. Therefore, this dose was tested with Humalog 
infusion in Part 2 in healthy adult subjects. In Part 2, all healthy subjects achieved GIRmax > 4 
mg/kg/min. A dose of MK-1092 8.0 nmol/kg was therefore used as the initial dose in Part 3 
(adult subjects with T1DM). After 8.0 nmol/kg was tested in Part 2, subsequent panels in Part 
1 testing up to 64 nmol/kg have been resumed. A dose of 32 nmol/kg was used as the initial 
dose in Part 4 (adult subjects with T2DM). A dose of 16 nmol/kg was used as the second 
dose in Part 4 so as to explore the PD effects of doses below 32 nmol/kg. These doses have 
been safe and well-tolerated.

Rationale for the Trial and Selected Subject Population
4.2.1
This study is being conducted to assess the initial clinical safety, tolerability, PK, and PD of 
MK-1092 following administration to humans.  PK after SC administration will be assessed.  
PD will be assessed by measuring the glucose infusion rate (GIR) after administration of 
MK-1092 under euglycemic clamp conditions.  In addition, the glycemic effect of Humalog 
infusion following SC MK-1092 administration will be assessed, also under euglycemic 
clamp conditions.

The study population is comprised of healthy male and female (women of non-child bearing 
potential, WONCBP) subjects, adult subjects with T1DM, and adult subjects with T2DM. In 
Parts 1 and 2 of the study, MK-1092 will be administered to healthy subjects to gain an initial 
understanding of the safety/tolerability, PK, and PD profile of MK-1092 prior to 
administration in adult subjects with T1DM and T2DM.  Because the target population for 
MK-1092 includes patients with T1DM and T2DM, including adult subjects with T1DM and 
T2DM in this protocol will provide an early read-out of the therapeutic potential for 
MK-1092. 
Adult subjects with T1DM and T2DM will not be administered MK-1092 until a safe and 
tolerated dose that achieves a GIR ~1-2 mg/kg/min (Part 1) and that has been tested with 
Humalog infusion (Part 2) in healthy adult subjects is identified. At the time of protocol 
amendment 03, a dose of 8.0 nmol/kg has fulfilled this requirement and was tested in Part 3
Panel G. Female subjects of child-bearing potential are not included in this study due to the 
limited assessment of MK-1092 on reproduction and development. At the time protocol 
amendment 03, approximately 77 subjects will participate in the study, including up to 
approximately 44 healthy male and female subjects (40 in Part 1, 4 in Part 2) in the age range 
of 18-50 years (inclusive), up to approximately 24 male and female adult subjects with 
T1DM (Part 3) in the age range of 18-60 years (inclusive), and up to approximately 9 male 
and female adult subjects with T2DM (Part 4) in the age range of 18-60 years (inclusive).
Rationale for Dose Selection/Regimen/Modification
4.2.2
As this is a Phase I assessment of MK-1092 in humans, and the pharmacokinetic, 
pharmacodynamic and safety profiles of the compound are still being evaluated,  
modifications to the dose or dosing regimen may be required to achieve the scientific goals 
of the trial objectives and/or to ensure appropriate safety monitoring of the trial subjects.

Design/Dosing/Procedures Modifications Permitted within Protocol Parameters.
As noted above, there are several objectives in this trial, extending beyond the standard goals 
of a FIH trial in understanding safety, tolerability, and PK.  Specifically, the trial is designed 
to also examine PD of MK-1092 with respect to the short-term glycemic effect of MK-1092 
across a range of doses in comparison to a single dose of glargine insulin, provide an 
assessment of the ability of MK-1092 to inhibit lipolysis, and test the glycemic effect of IV 
Humalog following SC administration of MK-1092.  Subjects in Parts 1, 3, and 4 will receive 
MK-1092 SC or glargine to assess safety, tolerability, PK, and PD from this mode of 
delivery. Healthy adult subjects in Part 2 will receive MK-1092 as well as an infusion of 
Humalog to explore the glucose-lowering potential of Humalog infusion after SC 
administration of MK-1092. Initiation of Part 2 occurred after safety and tolerability of 8.0 
nmol/kg dose after SC administration in Part 1 had been assessed. Adult subjects with T1DM 
in Part 3 and adult subjects with T2DM in Part 4 will receive MK-1092 SC or glargine to 
assess safety, tolerability, PK, and PD from this mode of delivery in a target patient 
population. The first panel of Part 3 tested MK-1092 8.0 nmol/kg SC, a dose demonstrated to 
be safe and tolerated in healthy subjects, that has achieved GIR ~1-2 mg/kg/min in Part 1, 
and that has been tested with Humalog infusion (Part 2) in healthy adult subjects. The first 
period of Part 4 will use MK-1092 32 nmol/kg, which was demonstrated to be safe and well-

tolerated in Part 1. Each subject in Part 4 will receive single dose administration in up to 
three different periods. This approach will allow for assessment of GIR at more than one 
dose level in subjects with T2DM. 
Rationale for the Use of Comparator/Placebo
4.2.2.1
In Parts 1, 3, and 4, glargine insulin will be administered to confirm the PD profile of 
glargine compared to MK-1092 and to serve as a safety comparator in healthy adult subjects 
(Part 1), in adult subjects with T1DM (Part 3), and in adult subjects with T2DM (Part 4). To 
facilitate blinding, subjects participating in Parts 1, 3, and 4 will receive injections of 
MK-1092/glargine and placebo matched to the alternative active treatment.  PD will be 
assessed as the GIR required to maintain the prespecified euglycemic clamp (~5% below 
fasting glucose levels for healthy adult subjects or at ~100 mg/dL for adult subjects with 
T1DM and T2DM). Both glargine and MK-1092 will be administered as a single SC dose.
Glargine 3.0 nmol/kg (0.5 units/kg) will be used in all panels of Parts 1 and 3 and all periods 
of Part 4. Glargine has been chosen as a comparator as it is a commonly used basal insulin in 
management of T1DM and T2DM. The 3.0 nmol/kg dose achieves GIR ~2 mg/kg/min 
between 6 and 18 hr after SC dosing in healthy adult subjects [3] and shown to have similar 
effects on GIR in adult subjects with T1DM [4]. Furthermore, the 3.0 nmol/kg dose has 
clinical relevance as it falls within a range of glargine used by patients with diabetes. Given 
underlying insulin resistance in subjects with T2DM, it is anticipated that GIR max following 
glargine 3.0 nmol/kg will be no higher in adult subjects with T2DM than healthy adult 
subjects and adult subjects with T1DM.
In Part 2, Humalog will be infused for 3 hr, starting ~12 hr after SC administration of 
MK-1092. The timing of the Humalog infusion has been chosen to correspond to a time at 
which MK-1092 is anticipated to have a glycemic effect, though the actual starting time of 
the Humalog infusion may be altered based on data from Part 1.  The dose of IV Humalog 
(0.2 units/kg = 1.2 nmol/kg over 3 hr) is near the range of insulin used in clinical practice to 
treat diabetic ketoacidosis. The GIR during IV Humalog infusion after SC administration of 
MK-1092 was anticipated to be > 4 mg/kg/min, which is a GIR above that required for 
suppression of hepatic glucose production [5], and likely ~9-11 mg/kg/min, which 
approaches the maximal GIR observed in the literature [6].
In addition to measuring GIR as a PD endpoint, serum free fatty acids (FFA) or non-
esterified fatty acids (NEFA) and plasma glycerol will also be assessed in all parts as a 
comparator for the lipolysis effect of MK-1092.  The PK of glargine will also be assessed in 
Parts 1, 3 and 4.
Starting Dose for This Trial
4.2.2.2
The proposed starting dose of MK-1092 for this trial is 4.0 nmol/kg SC, which will be 
administered to healthy adult subjects in Part 1.  This starting dose was selected in 
accordance with regulatory guidelines, which recommend a starting dose of 1/10 th the 
NOAEL at the human equivalent dose (HED) in the more sensitive species, correcting for
body surface area.  For MK-1092, the more sensitive species for calculating the starting dose 
is the dog, as it is the species in which the lowest HED can be identified.  The NOAEL SC

dose of 3.0 mg/kg/d (255.5 nmol/kg) supports the starting dose of 4.0 nmol/kg SC dose in 
humans, based on the following:
The bioavailability of MK-1092 in dogs is 0.67, which makes the 3.0 mg/kg/d SC dose 
roughly equivalent to 2.0 mg/kg IV, or 170 nmol/kg (molecular weight of MK-1092 is 
11,751 g/mol = 11,751 mg/mmol).  Multiplying 170 nmol/kg * 0.54 (correction for body 
surface area) = 91.8 nmol/kg * 0.1 (safety factor) = 9.18 nmol/kg.  This dose is calculated 
using the unlikely and highly conservative assumption of 100% bioavailability from SC 
administration in humans and still has a ~2.3x margin to the proposed initial SC dose of 4.0
nmol/kg.  Based on translational PK/PD modeling, the starting dose of 4.0 nmol/kg SC has a 
projected exposure of 9.1 nM*hr assuming F=0.4, which is the lowest bioavailability 
observed in pre-clinical species. The observed exposure of MK-1092 4.0 nmol/kg was 9.86
nM*hr, which supports the assumption of F ~ 0.4. The assumption of F=0.4 is used in 
subsequent calculations unless otherwise specified.   
The projected effective range for MK-1092 for clinical administration in both healthy adult 
subjects and adult subjects with T1DM has been estimated based on preclinical studies and 
extensive modeling to be 12.6 nmol/kg SC. The projected effective range for MK-1092 in 
adult subjects with T2DM may be twice as high (~ 25 nmol/kg SC) given the presence of 
insulin resistance in this population. This is the dose at which the GIR in a euglycemic clamp 
is expected to run at ~1-2 mg/kg/min, which is a generally accepted GIR for suppression of 
hepatic glucose production and thus a likely target for clinical dosing. A SC dose of 12.6
nmol/kg is projected to lead to an exposure (AUC0-24hr at steady state) of 29 nM*hr, 
assuming linear PK.  A range of exposure around this predicted therapeutic dose was 
anticipated in Part 1 between Panels B (8.0 nmol/kg SC) and C (16 nmol/kg SC). The 
observed AUC0-24h was 12.9 nM*h at 8.0 nmol/kg and 26.0 nM*h at 16 nmol/kg.
There were no adverse toxicities noted in pre-clinical studies. Reductions in blood glucose 
were observed as would be expected from the pharmacology of an insulin; thus, NOAELs for 
MK-1092 are derived from the top doses in both rat (20 mg/kg/d SC) and dog (3.0 mg/kg/d 
SC), which led to exposures of 3650 nM*hr and 479 nM*hr at 2 weeks, respectively.  The 
exposure margin is based on the dog levels and is thus ~52x for the 4.0 nmol/kg starting dose 
and ~16x for the 12.6 nmol/kg SC projected therapeutic dose.  
For Part 2, in which healthy adult subjects will be infused with Humalog after SC 
administration of MK-1092, the dose of MK-1092 that achieves the GIRmax of ~1-2 
mg/kg/min in Part 1 will be used. Therefore, Part 2 will not start until the starting dose to be 
used has been explored in Part 1 (without co-administration with Humalog). The dose that 
achieves GIR ~1-2 mg/kg/min will be used in Part 2 because it is a dose that will suppress 
hepatic glucose production and nears the target GIR for MK-1092 in healthy adult subjects 
and in adult subjects with T1DM. 
For Part 3, in which adult subjects with T1DM are receiving MK-1092 via SC injection, the 
first dose was 8.0 nmol/kg, as determined by data from Part 1. Specifically, the starting dose 
in Part 3 will be no higher than a safe and tolerated dose that achieves GIR ~1-2 mg/kg/min 
(Part 1) and that has been tested with Humalog infusion (Part 2) in healthy adult subjects. 
Dosing in Part 3 started after completion of the SC MK-1092 panel at the same or higher

dose in healthy adult subjects in Parts 1 and 2. Dosing in all subsequent panels of Part 3 will 
commence upon review of the safety data from previous panels within Part 3 and 
determination of an acceptable safety profile to continue dose escalation. The therapeutic 
exposure is expected to be similar in healthy adult subjects and adult subjects with T1DM.  
For Part 4, in which adult subjects with T2DM are receiving MK-1092 via SC injection, the 
first dose will be 32 nmol/kg, which is below the highest dose tested in Part 1 as of the time 
of protocol amendment 03 (64 nmol/kg MK-1092), and which was safe and well-tolerated.  
Dosing in all subsequent periods of Part 4 will commence upon review of the safety data 
from previous periods and determination of an acceptable safety profile to continue dose 
escalation. The therapeutic exposure is expected to be higher in adult subjects with T2DM 
than in healthy subjects or adult subjects with T1DM given the presence of greater insulin 
resistance.
Up to 3 doses of MK-1092 in Part 3 and up to 3 doses of MK-1092 in Part 4 will be 
administered in succession in each part; however, Part 3 and Part 4 may be dosed in parallel. 
The highest dose of MK-1092 in Part 3 and Part 4 will not exceed 64 nmol/kg SC, which is 
the highest planned clinical dose. Adult subjects with T1DM and T2DM may also be 
randomized to glargine in Part 3 and Part 4. The 3.0 nmol/kg dose (0.5 units/kg) of glargine 
is anticipated to achieve GIR ~2 mg/kg/min based on the literature [4] and is clinically 
relevant as it approximates a commonly used amount of insulin for patients with diabetes.
Maximum Dose/Exposure for This Trial
4.2.2.3
In preclinical toxicity studies, reductions in blood glucose, which were not considered 
adverse, were observed in both rat and dog. Biliary duct findings, which were also not
considered adverse, were observed in the dog only.  As directed by the CTA Guidance [ICH 
Topic M3 (R2)], the maximum allowable exposure in this trial is the lower exposure (AUC) 
in either species at the highest dose tested, as neither species demonstrated toxicity and at 
least 3 dose levels were assessed in both.
The upper range for dosing in this study has been selected based on preclinical studies, 
emerging clinical data, and extensive modeling to provide exposure levels several fold above 
those projected to be needed in subsequent clinical studies. For example, the therapeutic 
exposure level for insulin resistant subjects with T2DM is estimated to be 58 nM*h, which is 
twice that for healthy adult subjects and adult subjects with T1DM. Thus, the maximum dose 
in this study of 64 nmol/kg is projected to lead to an exposure (AUC0-∞) of 146 nM*hr, or 
~2.5x that required for therapeutic exposure in T2DM. In the highly unlikely setting of F=1, 
exposure at 64 nmol/kg SC could be 366 nM*hr, a value which is provided only as a highly 
conservative benchmark.  
As noted above, the lower NOAEL was observed in dog, in which a dose of 3.0 mg/kg/d SC 
led to an AUC0-24hr level of 479 nM*hr on the last day of dosing.  According to regulatory 
guidance, the maximum clinical dose should not lead to exposure levels that exceed this 
level.  The maximum SC dose of 64 nmol/kg has a predicted exposure margin for AUC0-∞ 
of ~3.3x assuming F=0.4 or ~1.3x assuming the highly unlikely F=1. Therefore, safety 
margins for this maximum planned clinical dose are adequate. Further, this dose may not be

administered if PD targets have been reached at earlier doses, if there are unexpected safety 
findings or if a revised projected exposure based on PK obtained during this trial would not 
lead to a satisfactory margin.  With respect to the reductions in blood glucose seen in the 
preclinical toxicity studies, note that subjects in this trial will be receiving a glucose infusion 
via the euglycemic clamp.  Subjects will be intensively monitored, with frequent assessment 
of blood glucose, even after discontinuation of the clamp.
Rationale for Dose Interval and Trial Design
4.2.2.4
MK-1092 is an insulin analog and thus will likely affect blood glucose, especially at higher 
doses.  As such, this study will use a continuous glucose infusion during the euglycemic 
clamp so that glucose levels remain in the euglycemic range and hypoglycemia is prevented.  
To this end, blood glucose will be monitored frequently (~every 5 minutes), allowing rapid 
changes to the rate of glucose infusion.  In addition to maintaining safety by avoiding 
hypoglycemia, the glucose infusion rate (GIR) will be the primary PD readout, as noted 
elsewhere.
In Part 1, six healthy adult subjects will be administered a SC dose of MK-1092 and two 
healthy adult subjects will be administered a SC dose of glargine 3.0 nmol/kg (0.5 units/kg) 
in each panel. Decisions to increase, decrease, or repeat SC dosing levels in Part 1 will be 
based on safety and tolerability data from prior panels.
In Part 1, healthy adult subjects will remain on the euglycemic clamp until the GIR has 
stabilized near 0 mg/kg/min and glucose infusion can be discontinued safely, at the discretion 
of the investigator. In a study of healthy adult subjects, glargine 3.0 nmol/kg (0.5 units/kg) 
SC demonstrated glucose-lowering activity during 24 h after administration with a GIR max of 
2.1-2.8 mg/kg/min [3]. Evidence from preclinical studies indicates that MK-1092 will have 
glucose lowering effect over at least 18 hr after SC administration. Subjects will be receiving 
a simultaneous infusion of glucose, with frequent assessment of blood glucose and necessary 
adjustments of the GIR to maintain glucose levels at the pre-specified level. While GIR may 
not return to a level close to 0 mg/kg/min at the same time in subjects receiving glargine and 
MK-1092 SC, all subjects will continue to be monitored similarly, to ensure both safety and 
blinding.
In Part 2, four healthy adult subjects will be administered a SC dose of MK-1092. The 
glycemic effect of IV Humalog following SC administration of MK-1092 will be examined
in the single panel of this part.  The dosing level of MK-1092 8.0 nmol/kg was determined
from data in Part 1, and was communicated with the site by a Protocol Clarification Letter 
prior to the dosing in Part 2. Subjects will receive MK-1092 at a dose expected to lead to a 
GIR ~1-2 mg/kg/min.  Subjects will also receive a 3 hr infusion of Humalog 1.2 nmol/kg IV 
(0.2 units/kg) at approximately 12 hr after SC administration of MK-1092, a time at which 
MK-1092 is anticipated to have a glycemic effect. The actual start time of Humalog infusion 
was confirmed as 12 h post-dose in a Protocol Clarification Letter prior to the dosing in Part 
2. As in Part 1, the GIR will be adjusted as necessary to maintain the pre-specified blood 
glucose level and subjects will remain on the euglycemic clamp until the GIR has stabilized
near 0 mg/kg/min and glucose infusion can be discontinued safely, at the discretion of the 
investigator.

In Part 3, six adult subjects with T1DM will be administered a SC dose of MK-1092 and two 
adult subjects with T1DM will be administered a SC dose of glargine 3.0 nmol/kg (0.5 
units/kg) in each panel. The dose in Panel G will be determined following review of data 
from Part 1 and will be no higher than a safe and tolerated dose that achieves GIR ~1-2 
mg/kg/min (Part 1) and has been tested with Humalog infusion (Part 2) in healthy adult 
subjects. As of the timing of amendment 03, the dose of 8.0 nmol/kg had fulfilled these 
requirements and was tested in Part 3 Panel G. Decisions to increase, decrease, or repeat SC 
dosing levels in Part 3 will be based primarily on safety and tolerability data from prior 
panels in Part 3, and doses may be increased up to the planned maximum clinical dose of 
64 nmol/kg SC.  The dose of Part 3 Panel G was communicated to the site by Protocol 
Clarification Letter prior to dosing.
In Part 3, the clamp will be completed when blood glucose is > 150 mg/dL for 30 minutes in 
the absence of exogenous glucose infusion or sooner at the discretion of the investigator; 
exogenous insulin will be given at this time. The duration of glycemic effect for glargine and 
MK-1092 in adult subjects with T1DM is anticipated to be the same as in healthy adult 
subjects. Subjects will be receiving a simultaneous infusion of glucose, with frequent 
assessment of blood glucose and necessary adjustments of the GIR to maintain glucose levels 
at the pre-specified level. While the clamp may not be completed at the same time in subjects 
receiving glargine and MK-1092 SC, all subjects will continue to be monitored similarly, to 
ensure both safety and blinding. After completion of the euglycemic clamp, adult subjects 
with T1DM will eat and resume their pre-study insulin regimen; however, they will continue 
to wear and use the insulin pump as needed until glycemic control has been re-established 
using the pre-study insulin therapy.
In Part 4, six adult subjects with T2DM will be administered a SC dose of MK-1092 and 
three adult subjects with T2DM will be administered a SC dose of glargine 3.0 nmol/kg 
(0.5 units/kg). Subjects who receive MK-1092 in Period 1 will receive MK-1092 in 
subsequent periods, and subjects who receive glargine in Period 1 will receive glargine in 
subsequent periods. The dose in Period 1 will be 32 nmol/kg based on this dose being a safe 
and tolerated dose in Part 1. Decisions to increase, decrease, or repeat SC dosing levels in 
Part 4 will be based primarily on safety and tolerability data from prior periods in Part 4, and 
doses may be increased up to the planned maximum clinical dose of 64 nmol/kg SC.  
In Part 4, the clamp will be completed when blood glucose is > 150 mg/dL for 30 minutes in 
the absence of exogenous glucose infusion or sooner at the discretion of the investigator; pre-
study anti-diabetic therapy, including insulin if appropriate, will be given following the end 
of the clamp at the discretion of the investigator. The duration of glycemic effect for glargine 
and MK-1092 in adult subjects with T2DM is anticipated to be the same as in healthy adult 
subjects. Subjects will be receiving a simultaneous infusion of glucose, with frequent 
assessment of blood glucose and necessary adjustments of the GIR to maintain glucose levels 
at the pre-specified level. While the clamp may not be completed at the same time in subjects 
receiving glargine and MK-1092 SC, all subjects will continue to be monitored similarly, to

Rationale for Endpoints
4.2.3
Safety Endpoints
4.2.3.1
As this is an early clinical investigation of MK-1092, safety will be carefully monitored. 
Physical examinations, vital signs, 12-lead electrocardiograms (ECG), laboratory safety tests 
(serum chemistry, hematology, and urinalysis) and monitoring of adverse experiences (AEs) 
will be assessed throughout the dosing intervals, with assessment collection times optimized 
based on the expected PK properties of MK-1092. Preclinical toxicology studies in rats and 
dogs did not demonstrate any adverse findings of concern and showed expected mechanism-
based reductions in blood glucose.  Specific restrictions are set forth in the inclusion and 
exclusion criteria regarding blood pressure, potassium levels, magnesium levels, and ECG 
findings, where only normal findings are acceptable for inclusion of subjects (see Section 5, 
Methodology, for details). Additional monitoring of potassium levels at the bedside may be 
performed at the discretion of the investigator.  Additionally, due to the fluid load required 
for a clamp procedure, normal blood pressure and adequate renal function will be required 
from a safety standpoint. Vital signs and ECG readings will be performed throughout the 
study to monitor any potential untoward effects (see Section 6.0, Trial Flow Chart, for 
details).  Subject discontinuation criteria for QTc abnormalities have been defined (see 
Section 5.8 and Appendix 12.4 for details). Standard chemistry, hematology and urinalysis 
panels will be assessed along with careful and frequent glucose monitoring.
MK-1092 administration could lead to anti-drug antibody (ADA) formation, which because 
of the nature of MK-1092 could also result in neutralizing antibodies that cross-react with 
insulin, thus forming anti-insulin antibodies (AIAs) that could result in insulin resistance.  
ADA and AIA will be assessed pre-dose and on Day 14 and Day 28 following cessation of 
treatment (see Section 7.1.5.3 for post-trial follow-up).  The changes in PD marker (blood 
glucose levels) will serve as a measure of potential neutralizing activity of ADA. Samples 
will be collected and banked for future analysis if clinical observations warrant such a need.  
To reduce the risk of ADA and AIA formation, only one MK-1092 administration per subject
was planned for Parts 1-3.
At the time of protocol amendment 04, no formation of ADA had been observed in healthy 
adult subjects in Part 1 Panels A-D, Part 2, or Part 3 Panels G and H at 14 or 28 days after 
one administration of MK-1092. In Part 1 Panel E, no ADA or AIA have been detected at 
14 or 28 days in 7 of 8 subjects; the 8th subject was lost to follow-up after 14 days and no 
ADA and AIA had been detected at up to 14 days. Based on these data, the risk of ADA 
development is anticipated to be minimal for subjects with T2DM (in Part 4) to receive more 
than one administration of MK-1092.
Pharmacokinetic Endpoints
4.2.3.2
The PK profile of MK-1092 will be assessed in all parts of the trial.  Subjects in Parts 1, 3, 
and 4 will have a single sample collected for glargine or MK-1092 PK, so treatment will 
remain blinded. Sufficiently sensitive assays for MK-1092 have been developed that will

allow determination of concentrations even at the lower dose levels in this protocol. No urine 
will be collected for PK.  
In Parts 1, 3, and 4, PK assessment will be critical in understanding PD. Specifically, the PD 
endpoint (GIRmax, see below) will be coupled with plasma MK-1092 concentration to 
determine the concentration–GIR response of MK-1092.  Similarly, the PD endpoint of 
GIRmax will also be coupled with glargine concentration for those subjects receiving glargine 
in Parts 1, 3, and 4. In addition, Cmax and Tmax, plasma exposure (AUC0-∞) will also be 
measured, as will apparent terminal half-life (t1/2) reflective of the absorption half-life after 
SC administration.
In Part 2, PK of MK-1092 will be collected throughout the infusion, similar to as in Part 1 
but at slightly different time points to correspond with the timing of Humalog infusion.  After 
Humalog administration, samples will continue to be collected for MK-1092 PK as well as 
additional samples will be collected for Humalog PK.  
Pharmacodynamic Endpoints
4.2.3.3
The primary objective in this study, in addition to the evaluation of safety, is to gain an 
understanding of the short term glycemic effects of MK-1092 as determined by GIR, as this 
will predict the ability of MK-1092 to function as a basal insulin with wide TI.  Evaluation of 
lipolysis markers will also be performed.
Euglycemic clamp is used in this study to determine the dose range in which MK-1092 is 
able to suppress hepatic glucose production without largely stimulating muscle glucose 
uptake. The effect of MK-1092 will be compared with that of glargine when administered at 
doses that also suppress hepatic glucose output.  At euglycemia, high doses of full agonist 
insulins such as Humalog require a maximum GIR of approximately 10-11 mg/kg/min to 
prevent hypoglycemia, reflecting a combination of suppressed hepatic glucose production 
(HGP) and insulin-mediated glucose disposal, primarily into muscle.  Previous studies have 
demonstrated that hepatic glucose production corresponds to a GIR of 1-2 mg/kg/min, while 
activation of muscle glucose uptake corresponds with GIRs of greater than 4 mg/kg/min 
[5][7]. GIRs between 2 and 4 mg/kg/min are attributed to inhibition of hepatic glucose 
uptake, in addition to changes in tissue-specific glucose utilization.  In a recent trial of the 
hepatoselective insulin peglispro, the highest GIR was around 4 mg/kg/min across a wide 
range of doses tested [8] which included a mild effect on presumed muscle uptake.  The 
range of acceptable GIRmax (1.5-4.5 mg/kg/min) in adult subjects with T1DM was selected to 
bracket the target GIR of ~2 mg/kg/min. Preclinical data show that IRPAs have greater 
glycemic effect in diabetic models. GIR will be adjusted to maintain blood glucose levels at 
~5% lower than the baseline fasted glucose levels for healthy adult subjects or ~100 mg/dL 
for adult subjects with T1DM and T2DM.  After and during the dosing of MK-1092 or 
glargine, glucose levels will be monitored at the bedside and the GIR will be adjusted 
accordingly.  The values of interest from the GIR are the individual GIRmax during the 
euglycemic clamp (Parts 1, 3, and 4), or individual GIRmax during infusion of Humalog (Part 
2).  In Part 1, GIR may differ in the subjects who receive MK-1092 and glargine, particularly 
in early panels which will use lower doses of MK-1092.  In Part 3, GIR is anticipated to be 
similar in the adult subjects with T1DM randomized to MK-1092 and glargine SC at the 
initial dose tested in Panel G; however, GIR may increase among adult subjects with T1DM

randomized to MK-1092 vs. glargine in subsequent panels as the dose of MK-1092 is 
escalated but glargine dose is unchanged. In Part 4, GIR may be higher in adult subjects with 
T2DM randomized to MK-1092 vs. glargine SC given planned doses of 32 nmol/kg in Period 
1 and ≤ 64 nmol/kg in Periods 2 and 3.
Insulin regulates lipolysis and ketosis in normal physiology, and MK-1092 is expected to 
have this activity as well.  To evaluate the effect on lipolysis, serum non-esterified fatty acids 
(NEFA, also known as FFA or free fatty acids) and plasma glycerol will be assessed in all 
parts. To assess ketosis, β-hydroxybutyrate will be assessed.  NEFA, glycerol, and
β-hydroxybutyrate will be correlated with MK-1092 PK and glucose PD to more fully 
understand the complete PD profile for MK-1092.
Planned Exploratory Biomarker Research
4.2.3.4
Planned Genetic Analysis
Understanding genetic determinants of drug response and the molecular basis of disease is an 
important endeavor during medical research. This research will evaluate whether genetic 
variation within a clinical trial population correlates with response to the treatment(s) under 
evaluation and/or disease. If genetic variation is found to predict efficacy or adverse events, 
the data might inform optimal use of therapies in the patient population. Knowledge of the 
molecular basis of disease contributes to the development of novel biomarkers and the 
identification of new drug targets. This research contributes to understanding molecular basis 
of disease and the genetic determinants of efficacy and safety associated with the treatments 
in this study.
Anti-Insulin and Anti-MK-1092 Antibodies
Both anti-insulin antibodies (AIA) and anti-drug antibodies (ADA) will be collected pre- and 
post-dosing in all 4 parts.  
Future Biomedical Research
4.2.3.5
The Sponsor will conduct Future Biomedical Research on specimens consented for future 
biomedical research during this clinical trial.  This research may include genetic analyses 
(DNA), gene expression profiling (RNA), proteomics, metabolomics (serum, plasma) and/or 
the measurement of other analytes, depending on which specimens are consented for future 
biomedical research.
Such research is for biomarker testing to address emergent questions not described elsewhere 
in the protocol (as part of the main trial) and will only be conducted on specimens from 
appropriately consented subjects. The objective of collecting/retaining specimens for Future 
Biomedical Research is to explore and identify biomarkers that inform the scientific 
understanding of diseases and/or their therapeutic treatments. The overarching goal is to use 
such information to develop safer, more effective drugs/vaccines, and/or to ensure that 
subjects receive the correct dose of the correct drug/vaccine at the correct time.  The details 
of this Future Biomedical Research sub-trial are presented in Section 12.2 – Collection and 
Management of Specimens for Future Biomedical Research.

6. Be judged to be in good health based on medical history, physical examination, vital 
sign measurements and ECG performed prior to randomization.  Appendix 12.4
provides a table of 12-Lead Electrocardiogram Abnormality Criteria. Subjects in Part 
4 will all have T2DM. Subjects with the following conditions may also be enrolled:
a.
Hypertension treated with lifestyle modification alone or stable doses (no 
change for ≥3 months) of ≤2 antihypertensive agents of the following drug 
classes: 
angiotensin 
converting 
enzyme 
inhibitors 
(ACE-inhibitors), 
angiotensin receptor blockers (ARBs), calcium channel blockers, and diuretics 
(chlorthalidone or a thiazide diuretic. Loop diuretics and beta-blockers are 
NOT permitted). 
b. Hypercholesterolemia with stable doses of treatment (no change for > 3 
months), including HMG-CoA reductase inhibitors (statins).  Subjects on 
alternative medications for hypercholesterolemia may be allowed, at the 
discretion of the Investigator and the Sponsor. 
c.
Subjects without history of myocardial infarction (MI) but who are on aspirin 
may be enrolled.  Subjects with a history of MI or atherosclerosis are not 
eligible.
d. Non-proliferative diabetic retinopathy, if subject is under the regular care of 
an ophthalmologist and is up-to-date and compliant with the prescribed 
ongoing evaluation and management. For subjects with known non-
proliferative diabetic retinopathy, a dilated ophthalmic exam must have been 
performed within 18 months of screening. If an exam was not performed 
within 18 months of screening, a dilated ophthalmic exam must be performed 
during the screening period either by their own ophthalmologist or an 
ophthalmologist associated with the clinical research unit. Subjects with other 
diagnosed complications of diabetes, such as peripheral neuropathy and/or 
moderately increased albuminuria (i.e., microalbuminuria ≥ 30 and ≤ 300mg 
urine albumin/g urine creatinine), may also be included. Urine microalbumin 
must be assessed at screening unless it has been confirmed to be ≤ 300mg 
urine albumin/g urine creatinine within 12 months of screening.   
e.
Other conditions, such as gastroesophageal reflux disease, obstructive sleep 
apnea, osteoarthritis, psoriasis, mood disorders and other chronic stable 
conditions may be allowed, at the discretion of the Investigator and Sponsor.
7. Be judged to be in good health based on laboratory safety tests (Section 7.1.3.1) 
obtained at the screening visit and from the laboratory safety tests obtained pre-
dosing, prior to administration of the initial dose of trial drug.  Appendix 12.5 
provides an algorithm for the assessment of out-of-range laboratory values. 
8. T2DM subjects are not required to have been on insulin.  If using insulin as 
background therapy, subjects should have a total daily insulin requirement of ≤ 1.2 
units/kg, and have been on stable doses of basal insulin over the 2-week period prior 
to screening and over the 2 weeks prior to dosing. Stability is defined as within 
approximately ±20% difference in total daily insulin doses. Insulin pump users will 
be allowed.

treatments in accordance with the protocol and any applicable laws and regulations.
Dose Selection/Modification
5.2.1
Dose Selection (Preparation)
5.2.1.1
The rationale for selection of doses to be used in this trial is provided in Section 4.0 –
Background & Rationale.  Specific calculations or evaluations required to be performed in 
order to administer the proper dose to each subject are outlined in a separate document 
provided by the Sponsor.
Dose Modification (Escalation/Titration/Other)
5.2.1.2
Dose escalation decisions will be based on key safety variables including, vital signs, 12-lead 
ECG, laboratory safety tests and adverse events  from the previous dose levels up to at least 
24 hours (or longer depending on the compound). Pharmacokinetic and pharmacodynamic 
data may be included in the dose escalation decisions.  See Background & Rationale -
Section 4.0.
If, as judged by the Sponsor and investigator, the safety and tolerability data do not justify 
dose escalation, the dose will not be increased as planned. Instead, subjects may:
●
receive the same dose level to further explore safety and tolerability at that level;
●
receive a lower dose of the trial drug;
●
receive the same or lower dose as a divided dose; or
●
receive a lower dose with or without food.
Or, dosing may be stopped. Subject discontinuation criteria are outlined in Section 5.8.
Prior to each treatment, the clinical and laboratory safety parameters from the previous dose 
level will be reviewed by the investigator and discussed with the Sponsor to permit a 
decision on whether to advance to the next higher dose level.  No dose escalation will occur 
without the joint agreement of the investigator and the Sponsor.
Timing of Dose Administration
5.2.2
MK-1092 and glargine will be prepared and dosed in the morning following a fast of at least 
8 hours per the instructions outlined in the Study Operations Manual.
Humalog will be prepared as per the instructions outlined in the Study Operations Manual.  
Infusion of Humalog will occur (in Part 2) approximately twelve hours after SC dosing of 
MK-1092, a time at which MK-1092 is anticipated to have a glycemic effect and GIR may be 
near maximal following MK-1092 administration.

Trial Blinding 
5.2.3
Part 2 is open-label; therefore, the Sponsor, investigator and subject will know the treatment 
administered.
For Parts 1, 3 and 4, a double-blinding technique will be used.  MK-1092 and glargine will 
be prepared and/or dispensed in a blinded fashion by an unblinded pharmacist or qualified 
trial site personnel. The subject and the investigator who is involved in the treatment or 
clinical evaluation of the subjects are unaware of the group assignments.
Subjects participating in Parts 1, 3 and 4 will receive injections of MK-1092/glargine and 
placebo matched to the alternative active treatment (i.e. subjects will receive either MK-1092 
and glargine-matched placebo, or glargine and MK-1092-matched placebo).
See Section 7.1.4.2, Subject Blinding/Unblinding, for a description of the method of 
unblinding a subject during the trial, should such action be warranted.
Randomization or Treatment Allocation
5.3
Subjects participating in Parts 1, 3 and 4 of this trial will be assigned randomly according to a 
computer-generated allocation schedule.  Sample allocation schedules for Parts 1, 3 and 4 are 
provided in Table 3, Table 5 and Table 6, respectively.
Subjects participating in Part 2 of this trial will be allocated by non-random assignment. A 
sample allocation schedule for Part 2 is provided in Table 4.

Concomitant Medications/Vaccinations (Allowed & Prohibited)
5.5
If a subject does not discontinue all prior medications within 14 days or 5 half-lives of 
starting the trial, he/she may be included in the study if the investigator can rationalize that 
the specific use of a prior medication is not clinically relevant within the context of the trial.
Concurrent use of any prescription or non-prescription medication, or concurrent vaccination,
during the course of the trial (i.e., after randomization or treatment allocation) must first be 
discussed between the investigator and Sponsor prior to administration, unless appropriate 
medical care necessitates that therapy or vaccination should begin before the investigator and 
Sponsor can consult.  The subject will be allowed to continue in the trial if both the Sponsor 
and the investigator agree.
For healthy adult subjects (Parts 1 and 2) ibuprofen may be used for minor ailments without
prior consultation with the Sponsor, and is permissible to have been taken prior to the trial.
For adult subjects with T1DM (Part 3) and T2DM (Part 4), ibuprofen may also be used for 
minor ailments without prior consultation with the Sponsor, and is permissible to have been 
taken prior to the trial. Insulin use is expected by all adult subjects with T1DM and for some 
subjects with T2DM prior to and during the study. Adult subjects with T1DM and T2DM 
may continue stable doses of statin drugs and certain antihypertensive medications. In 
addition, adult subjects with T2DM may take oral anti-diabetic medications, excluding 
thiazolidinediones, up to admission to the CRU for each period.
A standard daily multivitamin is permitted to be taken up to the time of admission to the 
CRU (without washout) and may be taken after discharge from the CRU.  Subjects taking 
other dietary supplements or vitamins must first be discussed between the investigator and 
Sponsor Clinical Director. No dietary supplements are permitted while domiciled in the 
CRU.
Listed below are specific restrictions for concomitant therapy during the course of the trial:
1. Acetaminophen/paracetamol use is not allowed by any subjects during the study 
(Parts 1-4). Acetaminophen/paracetamol is permitted to be taken up to the time of 
admission to the CRU (without washout) and may be taken after discharge from the 
CRU. 
2. Subjects with a history of hypercholesterolemia requiring medication are excluded 
from Parts 1-2 of the study. Therefore, lipid-lowering medications, including HMG-
CoA reductase inhibitors, are not allowed by any subjects in the study (Parts 1-2).
Subjects taking stable doses of HMG-CoA reductase inhibitors are allowed in Part 3 
and Part 4.
3. Adult subjects with T1DM or T2DM on aspirin for thrombosis prophylaxis, without 
history of MI, other thromboembolic event or atherosclerosis requiring procedural 
intervention, may remain on aspirin for the duration of the trial in Part 3 or Part 4, 
respectively.
4. Beta-blockers and loop diuretics are not allowed by any subjects in the study (Parts 
1-4).  Subjects on these medications will be excluded.

5. Systemic glucocorticoids are not allowed by any subjects in the study (Parts 1-4).  
Subjects on inhaled or topical glucocorticoids may be allowed, at the discretion of the 
investigator and Sponsor.
Other concomitant medications not addressed above (i.e., proton pump inhibitors, anti-
depressants) may be allowed, at the discretion of the investigator and Sponsor.
Rescue Medications & Supportive Care
5.6
To ensure subject safety, this study is conducted at an experienced Phase I clinical research 
unit with ACLS-trained medical staff available to intervene in case of severe hypoglycemia, 
or diabetic ketoacidosis. Resuscitative equipment and rescue treatment will be available at 
the clinical research unit during the trial. In addition, the clinical research unit has immediate 
access to a full service acute-care hospital to facilitate rapid institution of medical 
intervention if required. Refer to Appendix 12.6 for additional details on intervention for
hypo- and hyperglycemia.
Diet/Activity/Other Considerations
5.7
Diet Restrictions
5.7.1
Fasting requirements for trial procedures, such as but not limited to, laboratory safety 
evaluations, are specified in Section 7.0.
Subjects will fast from all food and drinks, except water, for at least 8 hours prior to the 
collection of blood for laboratory safety tests at the pre-trial (screening) and post-trial visits.  
All subjects will fast overnight for at least 8 hours prior to the start of the clamp and study 
drug administration procedures on Day 1.  
Subjects will remain fasted from all food and drinks except water during the euglycemic 
clamp and until approximately 1 hour after the end of the clamp procedure.  When subjects 
are not fasting, standard meals will be provided in accordance with the site’s standard 
schedule.   
Alcohol, Caffeine, Tobacco, Activity
5.7.2
Alcohol Restrictions 
5.7.2.1
Subjects will refrain from consumption of alcohol 24 hours prior to the pre- and post-trial 
visits and from 24 hours prior to and after trial drug administration in each treatment period. 
At all other times, alcohol consumption is limited to no more than approximately 3 alcoholic 
beverages or equivalent (1 glass is approximately equivalent to: beer [354 mL/12 ounces], 
wine [118 mL/4 ounces], or distilled spirits [29.5 mL/1 ounce]) per day.
Caffeine Restrictions

after trial drug administration in each treatment period. At all other times, caffeinated 
beverages or xanthine-containing products will be limited to no more than 6 units per day 
amounts (> 6 units: 1 unit=120 mg of caffeine).  
Smoking Restrictions 
5.7.2.3
Smoking (and/or the use of nicotine/nicotine-containing products) is not permitted during the 
trial.
Activity Restrictions
5.7.2.4
Subjects will avoid unaccustomed strenuous physical activity (i.e., weight lifting, running, 
bicycling, etc.) from the pre-trial (screening) visit until administration of the initial dose of 
trial drug, throughout the trial and until the post-trial visit.
Only light activity (walking) will be permitted within 24 hours of dosing in each treatment 
period through the time of discharge from the clinical research unit.
Contraception 
5.7.2.5
Male subjects with female partner(s) of child-bearing potential must agree to use a medically 
acceptable method of contraception during the trial and for 90 days after the last dose of trial 
drug. Males should use a condom. Female partners must additionally use one of the 
following methods if they are not pregnant: hormonal contraception, intra-uterine device, 
diaphragm, or cervical cap. If their partner is pregnant, males must agree to use a condom 
and no additional method of contraception is required for the pregnant partner. Male subjects 
must also agree to not donate sperm during the study and for a period of 90 days after the last 
dose of study drug. Abstinence is an alternative lifestyle and subjects practicing abstinence 
may be included in the trial.
Subject Withdrawal/Discontinuation Criteria
5.8
Discontinuation of Treatment
5.8.1
Discontinuation of treatment does not represent withdrawal from the trial.
As certain data on clinical events beyond treatment discontinuation may be important to the 
study, they must be collected through the subject’s last scheduled follow-up, even if the 
subject has discontinued treatment.  Therefore, all subjects who discontinue trial treatment
prior to completion of the treatment period will still continue to participate in the trial as 
specified 
in

Withdrawal/Discontinuation, or if available, Protocol Clarification Letter.
Subjects may discontinue treatment at any time for any reason or be dropped from treatment
at the discretion of the investigator should any untoward effect occur.  In addition, a subject 
may be discontinued from treatment by the investigator or the Sponsor if treatment is 
inappropriate, the trial plan is violated, or for administrative and/or other safety reasons.

Specific details regarding procedures to be performed at treatment discontinuation are 
provided in Section 7.1.4 – Other Procedures.
A subject must be discontinued from treatment but continue to be monitored in the trial for 
any of the following reasons:
○
The subject requests to discontinue treatment.
o
The subject’s treatment assignment has been unblinded by the investigator, Merck 
subsidiary or through the emergency unblinding call center. 
o
The subject has a medical condition or personal circumstance which, in the opinion of the 
investigator and/or Sponsor, placed the subject at unnecessary risk from continued 
administration of study drug/vaccine.
o
The subject has a positive urine drug screen at any time during the course of the trial. 
o
The subject has liver function test (ALT and/or AST) value of ≥3 times the upper limit 
of normal that are not associated with any plausible cause.  May consider discontinuation 
of study.
o
The subject has QTcF prolongation meeting pre-specified criteria (see Appendix 12.4).
For subjects who are discontinued from treatment, all applicable discontinuation activities 
will be performed according to Section 7.1.4.1 – Withdrawal/Discontinuation, or if available, 
Protocol Clarification Letter.
Discontinuation from treatment is “permanent.” Once a subject is discontinued, he/she shall 
not be allowed to restart treatment.
Withdrawal from the Trial
5.8.2
Subjects may withdraw from the trial at any time for any reason.  If a subject withdraws from 
the trial, they will no longer receive treatment or be followed at scheduled protocol visits.
A subject must be withdrawn from the trial if:
○
The subject withdraws consent from the study.
o
The subject is lost to follow-up
Specific details regarding procedures to be performed at the time of withdrawal from the trial 
including the procedures to be performed should a subject repeatedly fail to return for 
scheduled visits and/or if the study site is unable to contact the subject, as well as specific 
details regarding withdrawal from Future Biomedical Research are outlined in Section 7.1.4 
– Other Procedures.
Subject Replacement Strategy
5.9
If a subject discontinues from the trial, a replacement subject may be enrolled if deemed 
appropriate by the investigator and Sponsor.  The replacement subject will generally receive 
the same treatment or treatment sequence (as appropriate) as the subject being replaced. The

replacement subject will be assigned a unique treatment/randomization number. The trial site 
should contact the Sponsor for the replacement subject’s treatment/randomization number.
For Part 4 only, the replacement subject may begin dosing at the subsequent dose level for 
that part, upon agreement between the investigator and Sponsor.
Beginning and End of the Trial
5.10
The overall trial begins when the first subject signs the informed consent form.  The overall 
trial ends when the last subject completes the last study-related phone-call or visit, withdraws 
from the trial or is lost to follow-up (i.e. the subject is unable to be contacted by the 
investigator).
A trial may be paused during review of newly available preclinical/clinical safety, 
pharmacokinetic, pharmacodynamic, efficacy or biologic data or other items of interest, prior 
to a final decision on continuation or termination of the trial.  It may be necessary to keep the 
trial open for gathering/reviewing of additional supportive data to optimally complete the 
objective(s) of the trial.  If necessary, the appropriate amendment(s) to the protocol and/or 
appropriate communication(s) will be generated.  If the decision has been made to end the 
study following this review period, the study end will be defined as the date of the Sponsor 
decision and this end of study date supersedes the definitions outlined above.  The 
Competent 
Authority(ies) 
and 
Institutional 
Review 
Board(s)/Independent 
Ethics 
Committee(s) [IRB(s)/IEC(s)] will be appraised of the maximum duration of the trial be yond 
the last subject out and the justification for keeping the trial open.
Clinical Criteria for Early Trial Termination
5.11
There are no pre-specified criteria for terminating the trial early.
A primary objective of this early Phase I trial is to identify the maximum safe and well-
tolerated dose and/or dosing regimen that achieve pharmacokinetic, pharmacodynamic and/or 
biologic targets in humans based on preclinical or early clinical data.  Therefore, it is possible 
that trial subjects may not receive all doses specified in the protocol if this objective is 
achieved at lesser dose levels in this trial.  This would not be defined as early termination of 
the trial, but rather an earlier than anticipated achievement of the trial objective(s).  If a 
finding (e.g., pharmacokinetic, pharmacodynamic, efficacy, biologic targets, etc.) from 
another preclinical or clinical trial using the trial treatment(s), comparator(s), drug(s) of the 
same class, or methodology(ies) used in this trial, results in the trial(s) or program being 
stopped for non-safety reasons, this also does not meet the definition of early trial 
termination.
Early trial termination is defined as a permanent discontinuation of the trial due to 
unanticipated concerns of safety to the trial subjects arising from clinical or preclinical trials 
with the trial treatment(s), comparator(s), drug(s) of the same class or methodology(ies) used 
in this trial.

repeated on a second screening day at the discretion of the study investigator. Prior to each period, HR and BP will be triplicate measurements obtained at least 1-2 min apart
within approximately 60 min of dosing MK-1092/glargine. The median of these measurements will be used as the baseline. Post-dose vital sign measurements will be single 
measurements. Post-dose vital sign assessments will be done at 30 min (0.5 hr), 60 min (1.0 hr), 180 min (3.0 hr), 360 min (6.0 hr), 9.0 hr, 12 hr, 18 hr, 24 hr, 30 hr, and 36 hr. 
Measurements will also be collected at 48 hr and Post Trial (Day 14).

Study drug will be administered at Time 0.
g.
All adverse experiences (including serious adverse events) will be reported from the signing of informed consent through Day 33 (5 days from Day 28) for randomized 
subjects only. If a subject is required to return for additional post-trial visits for the continued assessment of ADAs/AIAs after Day 28 (+/- 3 days), a subsequent phone call 
should be made to the subject 5 (+2) days after the last protocol-specified procedure to determine if any adverse events have occurred since the previous contact for the 
assessment of AEs. Refer to Section 7.2 for pre-randomization/allocation AE/SAE reporting requirements.
h.
Injection site local tolerability assessment will be recorded as an adverse experience (AE) if any reactions are identified.
i.
For postmenopausal females without menses for at least 1 year.
j.
Screening UDS is mandatory, any additional UDS are conducted per site SOP
k.
This sample should be drawn for planned analysis of the association between genetic variants in DNA and drug response.  This sample will not be collected at the site if there 
is either a local law or regulation prohibiting collection, or if the IRB/IEC does not approve the collection of the sample for these purposes. If the sample is collected, leftover 
extracted DNA will be stored for future biomedical research if the subject signs the FBR consent. If the planned genetic analysis is not approved, but FBR is approved and 
consent is given, this sample will be collected for the purpose of FBR.
l.
Leftover main study plasma will be stored for future biomedical research if the subject consents to future biomedical research.
m.
Blood for MK-1092 and glargine PK assay will be collected at the following timepoints -15 min (predose), 10, 30, 60, 90, 120, 180, 240, 360, 540, 720, 1080, 1440 min, 48 hr, 
72 hr, 96 hr, 120 hr and 168 hr following start of injection (i.e. - 15 min, 10 min, 30 min, 1.0 hr, 1.5 hr, 2.0 hr, 3.0 hr, 4.0 hr, 6.0 hr, 9.0 hr, 12 hr, 18 hr, 24 hr, 2d, 3d, 4d, 5d  
and 7d after SC dose). Blood will also be collected at Post-trial (Day 14 and Day 28). Exploratory analysis for MK-1092 metabolites may be performed. A sample will also be 
collected at Post clamp. Note that subjects will have only one (1) sample collected for MK-1092 and glargine PK at each time point and this sample will be processed and 
shipped to the appropriate laboratory for the respective PK assay (MK-1092 PK or glargine PK) by the unblinded lab personnel.
n.
Glucose infusion will be discontinued at the discretion of the investigator as detailed in the Study Operations Manual. The duration of the infusion may be shorter or longer 
than the 24 hr noted above.
o.
Plasma for bedside glucose analysis should be collected at approximately -5 min predose and ~every 1 to 5 min. If necessary, collection may be performed more frequently at 
investigator’s discretion.  Bedside glucose analysis will continue at the discretion of the investigator and will be dependent on the duration of the clamp procedure.  The 
duration of bedside glucose analysis may be shorter or longer than the 24 hr noted above.  Additional glucose measurements will be assessed using Yellow Springs Instrument 
(YSI) per the Study Operations Manual and site SOP.
p.
Post-clamp procedures are to be performed shortly after the completion of the clamp (up to +10 mins), unless the clamp is concluded within 30 min of a previous collection 
time. 
q.
Discharge should occur at a minimum of 48 hr after the start of the euglycemic clamp at the discretion of the investigator, post subject evaluation. After the end of the clamp 
procedures subjects may engage in normal activities, and will not be fasted. Subjects are discharged on Day 3, but return to the CRU on Days 4, 5, 6, 8, 14 and 28 for PK 
draws.
r.
If a subject has a positive drug-induced ADA/AIA titer at Day 28 follow-up visit, an additional sample will be drawn on Day 56 (+/- 5 days); additional sampling may be 
required (see Section 7.1.5.3 for more details).
s.
VS measurements prior to and including 6.0 hr may be collected +/- 15 min from the timepoint. The VS measurement after 6.0 hr may be collected +/- 30 min from the 
timepoint.
t.
Post-trial visits will be conducted Day 14 (+/-2) and Day 28 (+/- 3).

Clarification Letter when determined, but the total number of samples will not change. Note that subjects will have only one (1) sample collected for MK-1092 and glargine
PK at each time point and this sample will be processed and shipped to the appropriate laboratory for the respective PK assay (MK-1092 PK or glargine PK) by the unblinded 
lab personnel.
n. 
IV infusion of insulin and dextrose, as needed, will begin at the start of the 8 hr overnight fast on Day -1. IV insulin will be weaned following SC dosing with 
MK-1092/glargine in order to maintain glucose concentrations at ~100 mg/dL.  
o. 
Glucose infusion will be discontinued at the discretion of the investigator as detailed in the Study Operations Manual. The duration of the infusion may be shorter or longer 
than the 24 hr noted above.
p.
Plasma for bedside glucose analysis should be collected at approximately -5 min predose and ~every 1 to 5 min. If necessary, collection may be performed more frequently at 
investigator’s discretion. Bedside glucose analysis will continue at the discretion of the investigator and will be dependent on the duration of the clamp procedure.  The 
duration of bedside glucose analysis may be shorter or longer than the 24 hr noted above. Additional glucose measurements will be assessed using Yellow Springs Instrument 
(YSI) per the Study Operations Manual and site SOP.

q. 
Post-clamp procedures are to be performed shortly after the completion of the clamp (up to +10 min), unless the clamp is concluded within 30 min of a previous collection 
time. 
r. 
Discharge should occur at a minimum of 48 hr after the start of the euglycemic clamp at the discretion of the investigator, post subject evaluation. After the end of clamp 
procedures, subjects may engage in normal activities, and will not be fasted.  Subjects are discharged on Day 3, but return to the CRU on Day 4, 5, 6, 8, 14, and 28  for PK 
draws.
s. 
If a subject has a positive drug-induced ADA/AIA titer at the Day 28 follow-up visit, an additional sample will be drawn on Day 56 (+/- 5 days); additional sampling may be 
required (see Section 7.1.5.3 for more details).
t.
VS measurements prior to and including 6.0 hr may be collected +/- 15 min from the timepoint. The VS measurement after 6.0 hr may be collected +/- 30 min from the 
timepoint. 
u.
Glucose assessments (from fingersticks and/or CGM) should occur before meals, before bedtime (~11:00 PM), and as needed overnight from admission to the CRU until Day 
3.  If a subject remains domiciled in the CRU past Day 3, glucose assessments should occur at the discretion of the investigator until the time of discharge.
v.
Post-trial visits will be conducted Day 14 (+/-2) and Day 28 (+/- 3) after the last dose of trial drug.
w. C-peptide is to be measured at screening unless a documented measurement was obtained within 24 weeks prior to screening. To assess inclusion criteria 7, C-peptide must be 
measured when plasma glucose is >90 mg/dL (> 5.0 mM). If necessary, the subject may consume carbohydrates to raise plasma glucose over 90 mg/dL (5.0 nM) as measured 
by point of care analyzer (YSI or GlucoScout) prior to drawing blood for C-peptide. This may be repeated by the site as needed to ensure C-peptide is assessed when plasma 
glucose concentration is >90 mg/dL (> 5.0 mM).

a.
Subjects will participate in all periods (Periods 1 – 3).
b.
Screening should be done within 30 days of Day 1 in Period 1.
c.
Weight obtained at baseline (Day -1) in each period will be used for determining amount of drug to be administered for that period.
d.
All ECGs will be obtained in triplicate at least 1-2 min apart.  Prior to each period, predose ECGs will be obtained within 1-2 hr prior to dosing. The median of these 
measurements will be used as the baseline. During the infusion period post baseline ECG measurements will be taken at 60 min (1.0 hr), 180 min (3.0 hr), 360 min (6.0 hr), 9.0 
hr, 12 hr, 18 hr, 24 hr, 30 hr and 36 hr. Measurements will also be collected at Post clamp, 48 hr and Post Trial (Day 14 relative to the last period dosed). 
e.
At screening, the median of 3 measurements taken within a 10-min period (all 3 sets completed within 10 min) will be used to assess for subject eligibility. This may be 
repeated on a second screening day at the discretion of the study investigator. Prior to each period, HR and BP will be triplicate measurements obtained at least 1-2 min apart
within approximately 60 min of dosing MK-1092/glargine. The median of these measurements will be used as the baseline. Post-dose vital sign measurements will be single 
measurements. On the day of MK-1092/glargine administration, post-dose Vital Sign assessments will be done at 30 min (0.5 h), 60 min (1.0 hr), 180 min (3.0 hr), 360 min 
(6.0 hr), 9.0 hr, 12 hr, 18 hr, 24 hr, 30 hr, and 36 hr. Measurements will also be collected at 48 hr and Post Trial (Day 14 relative to the last period dosed).

7.0 TRIAL PROCEDURES
Trial Procedures
7.1
The Trial Flow Chart - Section 6.0 summarizes the trial procedures to be performed at each 
visit.  Individual trial procedures are described in detail below.  It may be necessary to 
perform these procedures at unscheduled time points if deemed clinically necessary by the 
investigator.
Furthermore, additional evaluations/testing may be deemed necessary by the investigator and 
or the Sponsor for reasons related to subject safety. In some cases, such evaluation/testing 
may be potentially sensitive in nature (e.g., HIV, Hepatitis C, etc.), and thus local regulations 
may require that additional informed consent be obtained from the subject.  In these cases, 
such evaluations/testing will be performed in accordance with those regulations.
Administrative Procedures
7.1.1
Informed Consent
7.1.1.1
The investigator or qualified designee must obtain documented consent from each potential 
subject prior to participating in a clinical trial or Future Biomedical Research. If there are 
changes to the subject’s status during the trial (e.g., health or age of majority requirements), 
the investigator or qualified designee must ensure the appropriate consent is in place. 
7.1.1.1.1 General Informed Consent
Consent must be documented by the subject’s dated signature on a consent form along with 
the dated signature of the person conducting the consent discussion. 
A copy of the signed and dated consent form should be given to the subject before 
participation in the trial.
The initial informed consent form, any subsequent revised written informed consent form
and any written information provided to the subject must receive the IRB/ERC’s 
approval/favorable opinion in advance of use.  The subject should be informed in a timely 
manner if new information becomes available that may be relevant to the subject’s 
willingness to continue participation in the trial.  The communication of this information will 
be provided and documented via a revised consent form or addendum to the original consent 
form that captures the subject’s dated signature.
Specifics about a trial and the trial population will be added to the consent form template at 
the protocol level.  
The informed consent will adhere to IRB/IEC requirements, applicable laws and regulations 
and Sponsor requirements.

7.1.1.1.2 Consent and Collection of Specimens for Future Biomedical Research
The investigator or qualified designee will explain the Future Biomedical Research consent 
to the subject, answer all of his/her questions, and obtain written informed consent before 
performing any procedure related to the Future Biomedical Research sub-trial.  A copy of the 
informed consent will be given to the subject.
Inclusion/Exclusion Criteria
7.1.1.2
All inclusion and exclusion criteria will be reviewed by the investigator or qualified designee 
to ensure that the subject qualifies for the trial.
Subject Identification Card
7.1.1.3
All subjects will be given a Subject Identification Card identifying them as participants in a 
research trial. The card will contain trial site contact information (including direct telephone 
numbers) to be utilized in the event of an emergency. The investigator or qualified designee 
will provide the subject with a Subject Identification Card immediately after the subject 
provides written informed consent. At the time of treatment allocation/randomization, site 
personnel will add the treatment/randomization number to the Subject Identification Card.
The subject identification card also contains contact information for the emergency 
unblinding call center so that a health care provider can obtain information about trial 
medication/vaccination in emergency situations where the investigator is not available.
Medical History
7.1.1.4
A medical history will be obtained by the investigator or qualified designee.
Prior and Concomitant Medications Review
7.1.1.5
7.1.1.5.1 Prior Medications
The investigator or qualified designee will review prior medication use, including any 
protocol-specified washout requirement, and record prior medication taken by the subject 
within 14 days before starting the trial.
7.1.1.5.2 Concomitant Medications
The investigator or qualified designee will record medication, if any, taken by the subject 
during the trial.
Assignment of Screening Number
7.1.1.6
All consented subjects will be given a unique screening number that will be used to identify 
the subject for all procedures that occur prior to randomization or treatment allocation.  Each 
subject will be assigned only one screening number.  Screening numbers must not be re-used 
for different subjects.

Any subject who is screened multiple times will retain the original screening number 
assigned at the initial screening visit.
Specific details on the screening visit requirements (screening/rescreening) are provided in 
Section 7.1.5.1.  
Assignment of Treatment/Randomization Number
7.1.1.7
All eligible subjects will be randomly allocated and will receive a treatment/randomization 
number.  The treatment/randomization number identifies the subject for all procedures 
occurring after randomization.  Once a treatment/randomization number is assigned to a 
subject, it can never be re-assigned to another subject.
A single subject cannot be assigned more than 1 treatment/randomization number.
Trial Compliance (Medication/Diet/Activity/Other)
7.1.1.8
Administration of trial medication will be witnessed by the investigator and/or trial staff.
Clinical Procedures/Assessments
7.1.2
Physical Exam:
The physical exam assessments will be defined and conducted per the site SOP.
Body Weight and Height
Body weight and height will be obtained with the subject’s shoes off, jacket or coat removed.
The subject’s weight is to be documented in kilograms (kg), to the nearest 0.1 kg and the 
subject’s height is to be documented in meters, to the nearest 0.01 meter (0.01 meter = 1 
centimeter, cm).
Body Mass Index (BMI)
BMI equals a person's weight in kilograms divided by height in meters squared. 
(BMI=kg/m2).  
12-Lead ECG
Special care must be taken for proper lead placement by qualified personnel. Skin should be 
clean and dry prior to lead placement.  Subjects may need to be shaved to ensure proper lead 
placement.  Female subjects may need to remove their bra.  
Subjects should be resting in the semi-recumbent position for at least 10 minutes prior to 
each ECG measurement.  
The correction formula to be used for QTc is Fredericia.

If repeat ECGs are required the clinical site will decide whether to leave the electrodes in 
place or mark the position of the electrodes for subsequent ECGs.  To mark the position of 
the electrodes, 12-lead electrode sites will be marked on the skin of each subject with an 
ECG skin marker pen to ensure reproducible electrode placement.
In all treatment periods, all ECGs will be obtained in triplicate, and the median of all 
parameters will be calculated. There should be ~1-2 minute intervals between ECG 
measurements. Predose ECGs will be obtained in triplicate at least 1-2 minutes apart within 
1-2 hours prior to dosing MK-1092/glargine.  The median of these measurements will be 
used as the baseline to calculate change from baseline for safety evaluations (and for 
rechecks, if needed).
During each treatment period, if a subject demonstrates an increase in QTc interval ≥60 
msec compared with median predose baseline measurement, the ECG will be repeated twice 
within 5 minutes.  The median value of the QTc interval from the 3 ECGs will represent the 
value at that time point.  If the QTc interval increase from baseline for any postdose time 
point is ≥60 msec, the subject will continue to be monitored by repeat 12-lead ECGs every 
15 minutes for at least 1 hour or until the QTc is within 60 msec of baseline.  If prolongation 
of the QTc interval ≥60 msec persists, a consultation with a study cardiologist may be 
appropriate and the Sponsor should be notified.
If the QTc interval is 500 msec, the Sponsor should be notified and the ECGs should be 
reviewed by a cardiologist. The subject should be telemetry-monitored (until the QTc is <500 
msec) or should be considered for transfer to a location where closer monitoring and 
definitive care (e.g., a Cardiac or Intensive Care Unit) is available.
Monitoring of potassium levels at the bedside will be performed as deemed necessary at the 
discretion of the investigator.
If the subject has unstable hemodynamics, or has any clinically significant dysrhythmias 
noted on telemetry, the subject should be immediately transferred to an acute care setting for 
definitive therapy.  
A study cardiologist should be arranged by the Principal Investigator or designee to be 
available as needed to review ECG tracings with significant abnormalities observed at any 
point during the trial.
Body Temperature
Body temperature will be measured with an oral, temporal artery, or tympanic thermometer. 
The same method (e.g., oral, temporal, or tympanic) must be used for all measurements for 
each individual subject and should be the same for all subjects.
Vital Sign Measurements (Heart Rate and Blood Pressure)
Subjects should be resting in a semi-recumbent position for at least 10 minutes prior to 
having vital sign measurements obtained.  Semi-recumbent vital signs will include heart rate 
(HR) and blood pressure (BP).  The correct size of the blood pressure cuff and the correct

positioning on the subject’s arm is essential to increase the accuracy of blood pressure 
measurements. The same method (e.g., manual or automated) must be used for all 
measurements for each individual subject and should be the same for all subjects.
At screening, HR and BP will be triplicate measurements obtained within a 10-minute period 
(all 3 sets completed within 10 minutes) and the median of the three measurements will be 
used to assess for subject eligibility. This may be repeated on a second screening day at the 
discretion of the study investigator. 
The predose (baseline) HR and BP will be triplicate measurements obtained at least 1-2 
minutes apart within 60 minutes of dosing with study drug (MK-1092/glargine).  The median 
of these measurements will be used as the baseline to calculate change from baseline for 
safety evaluations (and for rechecks, if needed).  Post-dose vital sign measurements will be 
single measurements regardless of treatment assignment.
Glucose Clamp
The glucose clamp technique will be applied in this study, with each subject receiving an 
infusion of exogenous glucose (20% dextrose) during and after study drug administration.  
Glucose infusions will be adjusted to maintain a stable blood glucose target in the 
euglycemic range (~5% below fasting level for healthy adult subjects and ~100 mg/dL for 
adult subjects with T1DM and adult subjects with T2DM).  The clamp will be maintained 
after SC injection of MK-1092/glargine in Parts 1, 3, and 4, and after SC injection MK-1092 
followed by Humalog infusion Part 2, to characterize washout of the PD effect and to ensure 
safety.  For healthy adult subjects (Part 1 and 2), the clamp will be discontinued at the 
discretion of the investigator when the GIR appears stable near 0 mg/kg/min. For adult
subjects with T1DM (Part 3) and adult subjects with T2DM (Part 4), the clamp will be 
completed when blood glucose is >150 mg/dL for 30 minutes in the absence of exogenous 
glucose infusion or sooner at the discretion of the investigator; exogenous insulin will be 
given at this time if needed.
Blood glucose concentrations will be frequently measured by bedside analysis as a guide for 
adjusting the rate of glucose infusion.  Additional details are provided in the Study 
Operations Manual.

Other Procedures
7.1.4
Withdrawal/Discontinuation
7.1.4.1
The investigator or trial coordinator must notify the Sponsor when a subject has been 
discontinued/withdrawn from the trial.  If a subject discontinues for any reason at any time 
during the course of the trial, the subject may be asked to return to the clinic (or be 
contacted) for a post-trial visit (approximately 14 days after the last protocol-specified 
procedure) to have the applicable procedures conducted.  However, the investigator may 
decide to perform the post-trial procedures at the time of discontinuation or as soon as 
possible after discontinuation.  If the post-trial visit occurs prior to 14 days after the last 
protocol-specified procedure, the investigator should perform a follow-up phone call 14 days 
after the last protocol-specified procedure to determine if any adverse events have occurred 
since the post-trial clinic visit. An additional follow-up phone call should be made to the 
subject on Day 33 (+ 2 days) to determine if any adverse events have occurred since the last 
contact. For Parts 1 – 3, Day 33 is relative to Day 1 in each panel. In Part 4, Day 33 is 
relative to Day 1 of the last period dosed prior to discontinuation.  Any adverse events which 
are present at the time of discontinuation/withdrawal should be followed in accordance with 
the safety requirements outlined in Section 7.2 - Assessing and Recording Adverse Events.
7.1.4.1.1 Withdrawal From Future Biomedical Research
Subjects may withdraw their consent for Future Biomedical Research.  Subjects may 
withdraw consent at any time by contacting the principal investigator for the main trial.  If 
medical records for the main trial are still available, the investigator will contact the Sponsor 
using the designated mailbox (clinical.specimen.management@merck.com).  Subsequently,

the subject's consent for Future Biomedical Research will be withdrawn.  A letter will be sent 
from the Sponsor to the investigator confirming the withdrawal. It is the responsibility of the 
investigator to inform the subject of completion of withdrawal.  Any analyses in progress at 
the time of request for withdrawal or already performed prior to the request being received 
by the Sponsor will continue to be used as part of the overall research trial data and results.  
No new analyses would be generated after the request is received.
In the event that the medical records for the main trial are no longer available (e.g., if the 
investigator is no longer required by regulatory authorities to retain the main trial records) or 
the specimens have been completely anonymized, there will no longer be a link between the 
subject’s personal information and their specimens.  In this situation, the request for 
specimen withdrawal cannot be processed.
7.1.4.1.2 Lost to Follow-up
If a subject fails to return to the clinic for a required study visit and/or if the site is unable to 
contact the subject, the following procedures are to be performed:

The site must attempt to contact the subject and reschedule the missed visit.  If the 
subject is contacted, the subject should be counseled on the importance of 
maintaining the protocol-specified visit schedule.

The investigator or designee must make every effort to regain contact with the 
subject at each missed visit (e.g. phone calls and/or a certified letter to the 
subject’s last known mailing address or locally equivalent methods). These 
contact attempts should be documented in the subject’s medical record.

Note:  A subject is not considered lost to follow up until the last scheduled visit 
for the individual subject.  The amount of missing data for the subject will be 
managed via the pre-specified data handling and analysis guidelines
Subject Blinding/Unblinding
7.1.4.2
When the investigator or delegate needs to identify the drug used by a subject in case of 
emergency e.g., the occurrence of serious adverse events, he/she will contact the emergency 
unblinding call center by telephone and make a request for emergency unblinding.  As 
requested by the investigator or delegate the emergency unblinding call center will provide 
the information to him/her promptly and report unblinding to the Sponsor.  Prior to 
contacting the emergency unblinding call center to request unblinding of a subject’s 
treatment assignment, the investigator or delegate must enter the intensity/toxicity grade of 
the adverse events observed, the relation to study drug, the reason thereof, etc., in the medical 
chart etc.
Subjects whose treatment assignment has been unblinded
by the 
investigator/delegate and/or non-study treating physician must be discontinued from study 
drug, but should continue to be monitored in the trial.
Treatment/Vaccine identification information is to be unmasked ONLY if necessary for the 
welfare of the subject.  Every effort should be made not to unblind the subject unless 
necessary.

In the event that unblinding has occurred, the circumstances around the unblinding (e.g., 
date, reason and person performing the unblinding) must be documented promptly, and the 
Sponsor Clinical Director notified as soon as possible. Only the principal investigator or 
delegate and the respective subject’s code should be unblinded. Other trial site personnel and 
Sponsor personnel directly associated with the conduct of the trial should not be unblinded.
Domiciling
7.1.4.3
Healthy adult subjects participating in Parts 1 and 2 will report to the clinical research unit 
(CRU) on Day -1 prior to the scheduled day of trial drug administration on Day 1.  Subjects 
will remain in the unit until approximately 48 hours after the start of the euglycemic clamp.  
At the discretion of the investigator, subjects may be requested to remain in the CRU longer.
Adult subjects with T1DM participating in Part 3 will report to the CRU on Day -4 prior to 
the scheduled day of trial drug administration on Day 1.  Subjects will be placed on 
continuous glucose monitoring (CGM) and started on a SC insulin pump to maintain 
glycemic control with an appropriate regimen of basal and bolus insulin during washout of 
pre-study insulin therapy. Subjects who are already using a SC insulin pump for treatment of 
T1DM may continue to use their own SC pump during the study at the discretion of the 
investigator; however the investigator may alter the basal and bolus settings or require the 
use of a site-provided SC insulin pump based on medical judgment.  After completion of the 
euglycemic clamp, adult subjects with T1DM will eat and their pre-study insulin regimen
will be restarted at the discretion of the investigator; however, they will continue to wear the 
CGM and use the insulin pump as needed until glycemic control has been re-established 
using the pre-study insulin therapy.  Subjects will be discharged from site ~48 hours after the 
start of the clamp. The time of discharge may be dependent upon glycemic control being re-
established after the euglycemic clamp and can be lengthened based on investigator 
discretion. 
Following SC treatment, subjects will remain in the unit until approximately 48 hours after 
the start of the euglycemic clamp, when glucose levels are stable. Adult subjects with T1DM 
may continue to wear an insulin pump and CGM, even if these devices are not being used, 
until discharge or these devices may be removed prior to discharge based on the clinical 
judgement and discretion of the investigator. At the discretion of the investigator, subjects 
may be requested to remain in the CRU longer.
Adult subjects with T2DM participating in Part 4 will be admitted to the CRU on Day -4 
prior to the scheduled day of trial drug administration on Day 1 in each period and placed on 
continuous glucose monitoring (CGM). For all subjects with insulin-requiring T2DM, a SC 
insulin pump will be started to maintain glycemic control with an appropriate regimen of 
basal and bolus insulin. Subjects with non-insulin-requiring T2DM will not be placed on SC 
insulin pump unless the investigator determines this to be necessary to maintain glycemic 
control during the admission. 
Subjects who are already using a SC insulin pump for treatment of T2DM may continue to 
use their own SC pump during the study at the discretion of the investigator; however the 
investigator may alter the basal and bolus settings or require the use of a site-provided SC 
insulin pump based on medical judgment.

After completion of the euglycemic clamp, adult subjects with T2DM will eat and their pre-
study anti-diabetic regimen will be started at the discretion of the investigator; however, they 
will continue to wear the CGM and use the insulin pump as needed until glycemic control 
has been re-established using the pre-study anti-diabetic therapy, including insulin if needed.  
Subjects will be discharged from site ~48 hours after the start of the clamp. The time of 
discharge may be dependent upon glycemic control being re-established after the euglycemic 
clamp and can be lengthened based on investigator discretion. 
Following SC treatment, subjects will remain in the unit until approximately 48 hours after

being used, until discharge or these devices may be removed prior to discharge based on the 
clinical judgement and discretion of the investigator. At the discretion of the investigator, 
subjects may be requested to remain in the CRU longer.
Calibration of Critical Equipment
7.1.4.4
The investigator or qualified designee has the responsibility to ensure that any critical device
or instrument used for a clinical evaluation/test during a clinical trial that provides important 
information about inclusion/exclusion criteria and/or safety or efficacy parameters shall be 
suitably calibrated and maintained to ensure that the data obtained is reliable and/or 
reproducible.  Documentation of equipment calibration must be retained as source 
documentation at the trial site.
Critical Equipment for this trial includes:
ECG machine, equipment for vital signs measurements, glucometers, Yellow Springs 
Instrument (YSI) glucose analyzer, GlucoScout, syringe/infusion pumps for administering 
glucose and study drugs, CGM, and insulin pump.
Visit Requirements
7.1.5
Visit requirements are outlined in Section 6.0 - Trial Flow Chart. Specific procedure-related 
details are provided above in Section 7.1 - Trial Procedures.
Screening
7.1.5.1
Within 30 days prior to Day 1 in Parts 1 – 3, or prior to Day 1 in Period 1 for Part 4, potential 
subjects will be evaluated to determine that they fulfill the entry requirements as set forth in 
Section 5.1.
Subjects may be rescreened after consultation with the Sponsor. Rescreening should include 
all screening procedures listed in the protocol flow chart, including consent review. Rescreen 
procedures cannot be conducted the day prior to treatment allocation/randomization if there

Treatment Period Visit
7.1.5.2
Subcutaneous MK-1092 (Parts 1, 2, 3, and 4) or glargine (Parts 1, 3, and 4) will be 
administered as a one-time injection on Day 1 of each panel or period. Intravenous Humalog 
(Part 2) will be infused for 3 hours starting ~12 hours after the administration of SC 
MK-1092 on Day 1. The actual start time of Humalog infusion was confirmed based on data 
from Part 1 and was communicated to the site prior to dosing for Part 2. 
Exogenous glucose will also be infused concurrently with adjustments as needed to maintain 
a stable glucose concentration predefined by the subject’s baseline fasting glucose (Parts 1 
and 2), or protocol-defined target glucose (Parts 3 and 4), during the medication infusion and 
longer if necessary. Details of this euglycemic clamp technique are outlined in the Study 
Operations Manual.
Post-Trial
7.1.5.3
Subjects will be required to return to the clinic on Day 14 (+/- 2 days) in Part 1-3 or on Day 
14 (+/- 2 days) of the last period dosed in Part 4 for a post-trial visit for end of trial safety 
assessments (e.g. physical exam, ECG, VS, lab safety tests and AE assessments) and for the 
assessment of anti-drug antibodies (ADA) and anti-insulin antibodies (AIA).  Subjects will 
additionally be required to return to the clinic on Day 28 (+/- 3 days) in Parts 1-3 or on Day 
28 (+/- 3 days) of the last period dosed in Part 4 for collection of samples for assessment of 
ADA and AIA. A follow-up phone call should be placed to the subject on Day 33 (+2 days)
in Parts 1-3 or on Day 33 (+/- 2 days) of the last period dosed in Part 4 for the assessment of 
adverse experiences.  
If a subject has a drug-induced positive ADA/AIA response at the Day 28 (+/- 3 days) visit, 
an additional sample will be drawn on Day 56 (+/- 5 days) in Parts 1-3 or on Day 56 (+/- 5 
days) of the last period dosed in Part 4 after the completion of dosing. At the same time, 
fasting blood glucose will be assessed using point-of-care glucose analyzer (e.g. YSI) and an 
evaluation of possible signs and symptoms of hyperglycemia will be conducted.  If medically 
required the subject will be referred to an endocrinologist for further treatment.
Additional follow-ups will be conducted in subjects with detectable ADAs until one of the 
following occurs:
a) subject no longer has detectable drug-induced ADAs/AIAs,
b) Drug-induced ADAs/AIAs are persistent and stable (magnitude of response not 
significantly increasing) on 3 consecutive checks at Day 28, Day 56 and additional 3 
month intervals, if needed
Fasting blood glucose will be assessed by point-of-care glucose analyzer (e.g. YSI) at each 
time a subject returns for drug-induced ADA/AIA follow-up, and an evaluation of possible 
signs and symptoms of hyperglycemia will be conducted. Subjects will be referred to an 
endocrinologist if medically required. If a post-trial visit for the continued assessment of 
ADAs/AIAs occurs after Day 28 (+/- 3 days), a subsequent phone call should be made to the 
subject 5 (+2 days) after the last protocol-specified procedure to determine if any adverse 
events have occurred since the previous contact for the assessment of AEs.

Critical Procedures Based on Trial Objectives: Timing of Procedure 
7.1.5.4
For this trial, the critical procedures, in order of priority, are the glucose clamp procedures 
followed by the blood sample collections for MK-1092 and glargine.
Blood collection and other procedures directly related to the execution of the euglycemic 
clamp procedure need to be completed as close to the exact timepoint as possible.  In 
addition, at any post-dose time point, the blood sample for MK-1092 and for glargine need to 
be collected as close to the exact time point as possible.  All other procedures should be 
completed as close to the prescribed/scheduled time as possible. Trial procedures can be 
performed prior or after the prescribed/scheduled time.  
The order of priority can be changed during the trial with joint agreement of the investigator 
and the Sponsor Clinical Director.  
Any nonscheduled procedures required for urgent evaluation of safety concerns take 
precedence over all routine scheduled procedures.  
The following variance in procedure collection times will be permitted.

Parameters
This is a Phase I assessment of MK-1092 in humans, and the pharmacokinetic, 
pharmacodynamic and safety profiles of the compound is still being elucidated.  This 
protocol is written with some flexibility to accommodate the inherent dynamic nature of 
Phase I clinical trials.  Modifications to the dose, dosing regimen and/or clinical or laboratory 
procedures currently outlined below may be required to achieve the scientific goals of the 
trial objectives and/or to ensure appropriate safety monitoring of the trial subjects.  
As such, some alterations from the currently outlined dose and/or dosing regimen may be 
permitted based on newly available data, but the maximum daily dose may not exceed those 
currently outlined in the protocol.

Repeat of or decrease in the dose of the trial drug administered in any given period/panel

Interchange of doses between panels or periods

Entire period(s) or panel(s) may be omitted

Decrease in the duration of trial drug administration (e.g., number of hours) 

Remove a planned pharmacokinetic pause if agreed by Sponsor and investigator if no 
further increases in total daily dose

Addition of pharmacokinetic pause

Addition of operational pause

Decrease in the target glycemic level to be maintained during glucose infusion/clamp 
procedure

Decrease in the number of PK sampling timepoints

Modification of the PK/PD sample processing and shipping details based on newly 
available data
The pharmacokinetic/pharmacodynamic sampling scheme currently outlined in the protocol 
may be modified during the trial based on newly available pharmacokinetic or 
pharmacodynamic data (e.g., to obtain data closer to the time of peak plasma concentrations).  
If indicated, these collected samples may also be assayed in an exploratory manner for 
metabolites and/or additional pharmacodynamic markers.
Up to additional 50 mL of blood may be drawn for safety, pharmacokinetic, and/or 
pharmacodynamic analyses in Parts 1 – 3.  Up to an additional 100 mL of blood may be 
drawn for safety, pharmacokinetic, and/or pharmacodynamic analyses in Part 4.  This

includes additional blood that may be required for Yellow Springs Instrument (YSI) blood 
glucose assessments during the clamp procedure for safety. The total blood volume 
withdrawn from any single subject will not exceed the maximum allowable volume during 
his/her participation in the entire trial (Section 12.3). 
The timing of procedures for assessment of safety procedures (e.g., vital signs, ECG, safety 
laboratory tests, etc.) currently outlined in the protocol may be modified during the trial 
based on newly available safety, tolerability, pharmacokinetic or pharmacodynamic data 
(e.g., to obtain data closer to the time of peak plasma concentrations).  Additional laboratory 
safety tests may be added to blood samples previously drawn to obtain additional safety 
information (e.g., adding creatinine kinase to serum chemistry panel that was already drawn. 
These changes will not increase the number of trial procedures for a given subject during 
his/her participation in the entire trial. 
It is understood that the current trial may employ some or none of the alterations described 
above.  Any alteration made to this protocol to meet the trial objectives must be detailed by 
the Sponsor in a letter to the Trial File and forwarded to the investigator for retention.  The 
letter may be forwarded to the IRB/IEC at the discretion of the investigator.
Assessing and Recording Adverse Events
7.2
An adverse event is defined as any untoward medical occurrence in a patient or clinical 
investigation subject administered a pharmaceutical product and which does not necessarily 
have to have a causal relationship with this treatment. An adverse event can therefore be any 
unfavourable and unintended sign (including an abnormal laboratory finding, for example), 
symptom, or disease temporally associated with the use of a medicinal product or protocol-
specified procedure, whether or not considered related to the medicinal product or protocol-
specified procedure.  Any worsening (i.e., any clinically significant adverse change in 
frequency and/or intensity) of a preexisting condition that is temporally associated with the 
use of the Sponsor’s product, is also an adverse event.
Changes resulting from normal growth and development that do not vary significantly in 
frequency or severity from expected levels are not to be considered adverse events.  
Examples of this may include, but are not limited to, teething, typical crying in infants and 
children and onset of menses or menopause occurring at a physiologically appropriate time.
Sponsor's product includes any pharmaceutical product, biological product, device, 
diagnostic agent or protocol-specified procedure, whether investigational (including placebo 
or active comparator medication) or marketed, manufactured by, licensed by, provided by or 
distributed by the Sponsor for human use.
Adverse events may occur during clinical trials, or as prescribed in clinical practice, from 
overdose (whether accidental or intentional), from abuse and from withdrawal.
Adverse events, serious adverse events, and other reportable safety events that occur after the 
consent form is signed but before treatment allocation/randomization, must be reported by 
investigator for randomized participants only or participants enrolled in a run-in phase, if 
they are the result of a protocol-specified intervention, including but not limited to washout

last protocol-specified procedure if additional follow-up ADA/AIA assessment visits are 
required, all adverse events must be reported by the investigator. For Parts 1 – 3, Day 33 is 
relative to Day 1 in each panel. In Part 4, Day 33 is relative to Day 1 of the last period dosed.
Such events will be recorded at each examination on the Adverse Event case report 
forms/worksheets. The reporting timeframe for adverse events meeting any serious criteria is 
described in section 7.2.3.1. The investigator will make every attempt to follow all subjects 
with non-serious adverse events for outcome.
Electronic reporting procedures can be found in the Electronic Data Capture (EDC) data 
entry guidelines. Paper reporting procedures can be found in the Investigator Trial File 
Binder (or equivalent).
Definition of an Overdose for This Protocol and Reporting of Overdose to the 
7.2.1
Sponsor
The subject has taken (accidentally or intentionally) any drug administered as part of the 
protocol and exceeding the dose as prescribed by the protocol. It is up to the investigator or 
the reporting physician to decide whether a dose is to be considered an overdose, in 
consultation with the Sponsor.
If an adverse event(s) is associated with (“results from”) the overdose of Sponsor's product or 
vaccine, the adverse event(s) is reported as a serious adverse event, even if no other 
seriousness criteria are met.
If a dose of Sponsor's product or vaccine meeting the protocol definition of overdose is taken 
without any associated clinical symptoms or abnormal laboratory results, the overdose is 
reported as a non-serious Event of Clinical Interest (ECI), using the terminology “accidental 
or intentional overdose without adverse effect.”
All reports of overdose with and without an adverse event must be reported by the 
investigator within 24 hours to the Sponsor either by electronic media or paper. Electronic 
reporting procedures can be found in the EDC data entry guidelines. Paper reporting 
procedures can be found in the Investigator Trial File Binder (or equivalent).
Reporting of Pregnancy and Lactation to the Sponsor
7.2.2
Although pregnancy and lactation are not considered adverse events, it is the responsibility of 
investigators or their designees to report any pregnancy or lactation in a subject 
(spontaneously reported to them) that occurs during the trial.
Pregnancies and lactations that occur after the consent form is signed but before treatment 
allocation/randomization must be reported by the investigator if they cause the subject to be 
excluded from the trial, or are the result of a protocol-specified intervention, including but 
not limited to washout or discontinuation of usual therapy, diet, placebo treatment or a 
procedure.  Pregnancies and lactations that occur from the time of treatment

allocation/randomization through Day 33 (5 days after Day 28) following cessation of 
Sponsor’s product, or 5 days after the last protocol-specified procedure if additional follow-
up ADA/AIA assessment visits are required, must be reported by the investigator. For Parts 1 
– 3, Day 33 is relative to Day 1 in each panel. In Part 4, Day 33 is relative to Day 1 of the last 
period dosed.  All reported pregnancies must be followed to the completion/termination of 
the pregnancy. Pregnancy outcomes of spontaneous abortion, missed abortion, benign 
hydatidiform mole, blighted ovum, fetal death, intrauterine death, miscarriage and stillbirth 
must be reported as serious events (Important Medical Events). If the pregnancy continues to 
term, the outcome (health of infant) must also be reported.
Such events must be reported within 24 hours to the Sponsor either by electronic media or 
paper. Electronic reporting procedures can be found in the EDC data entry guidelines. Paper 
reporting procedures can be found in the Investigator Trial File Binder (or equivalent).
Immediate Reporting of Adverse Events to the Sponsor
7.2.3
Serious Adverse Events
7.2.3.1
A serious adverse event is any adverse event occurring at any dose or during any use of 
Sponsor's product that:
●
Results in death;
●
Is life threatening;
●
Results in persistent or significant disability/incapacity;
●
Results in or prolongs an existing inpatient hospitalization;
●
Is a congenital anomaly/birth defect;
●
Is an other important medical event.
Note: In addition to the above criteria, adverse events meeting either of the below criteria, 
although not serious per ICH definition, are reportable to the Sponsor in the same timeframe 
as SAEs to meet certain local requirements. Therefore, these events are considered serious by 
the Sponsor for collection purposes.
●
Is a cancer;
●
Is associated with an overdose.
Refer to Table 9 for additional details regarding each of the above criteria.
For the time period beginning when the consent form is signed until treatment 
allocation/randomization, any serious adverse event, or follow up to a serious adverse event, 
including death due to any cause, that occurs to any subject must be reported within 24 hours 
to the Sponsor if it causes the subject to be excluded from the trial, or is the result of a

protocol-specified intervention, including but not limited to washout or discontinuation of
usual therapy, diet, placebo treatment or a procedure.
For the time period beginning at treatment allocation/randomization through Day 33 (5 days 
after Day 28), or 5 days after the last protocol-specified procedure if additional follow-up 
ADA/AIA assessment visits are required, any serious adverse event, or follow up to a serious 
adverse event, including death due to any cause, whether or not related to the Sponsor's 
product, must be reported within 24 hours to the Sponsor either by electronic media or paper. 
Electronic reporting procedures can be found in the EDC data entry guidelines. Paper 
reporting procedures can be found in the Investigator Trial File Binder (or equivalent). For 
Parts 1 – 3, Day 33 is relative to Day 1 in each panel. In Part 4, Day 33 is relative to Day 1 of 
the last period dosed.
Additionally, any serious adverse event, considered by an investigator who is a qualified 
physician to be related to the Sponsor's product that is brought to the attention of the 
investigator at any time outside of the time period specified in the previous paragraph also 
must be reported immediately to the Sponsor.
All subjects with serious adverse events must be followed up for outcome.
Events of Clinical Interest
7.2.3.2
Selected non-serious and serious adverse events are also known as Events of Clinical Interest 
(ECI) and must be reported to the Sponsor.
For the time period beginning when the consent form is signed until treatment 
allocation/randomization, any ECI, or follow up to an ECI, that occurs to any subject must be 
reported within 24 hours to the Sponsor if it causes the subject to be excluded from the trial, 
or is the result of a protocol-specified intervention, including but not limited to washout or 
discontinuation of usual therapy, diet, placebo treatment or a procedure.
For the time period beginning at treatment allocation/randomization through Day 33 (5 days 
after Day 28) following cessation of treatment, or 5 days after the last protocol-specified 
procedure if additional follow-up ADA/AIA assessment visits are required, any ECI, or 
follow up to an ECI, whether or not related to the Sponsor’s product, must be reported within 
24 hours to the Sponsor, either by electronic media or paper.  Electronic reporting procedures 
can be found in the EDC data entry guidelines.  Paper reporting procedures can be found in 
the Investigator Trial File Binder (or equivalent). For Parts 1 – 3, Day 33 is relative to Day 1 
in each Panel. In Part 4, Day 33 is relative to Day 1 of the last period dosed.
Events of clinical interest for this trial include:
1. an overdose of Sponsor's product, as defined in Section 7.2.1 - Definition of an Overdose 
for This Protocol and Reporting of Overdose to the Sponsor, that is not associated with 
clinical symptoms or abnormal laboratory results.

2. an elevated AST or ALT lab value that is greater than or equal to 3X the upper limit of 
normal and an elevated total bilirubin lab value that is greater than or equal to 2X the 
upper limit of normal and, at the same time, an alkaline phosphatase lab value that is less 
than 2X the upper limit of normal, as determined by way of protocol-specified laboratory 
testing or unscheduled laboratory testing.*
*Note:  These criteria are based upon available regulatory guidance documents. The 
purpose of the criteria is to specify a threshold of abnormal hepatic tests that must trigger 
an additional evaluation for an underlying etiology. The trial site guidance for assessment 
and follow up of these criteria can be found in the Investigator Trial File Binder (or 
equivalent).
It may also be appropriate to conduct additional evaluation for an underlying etiology in 
the setting of abnormalities of liver blood tests including AST, ALT, bilirubin, and 
alkaline phosphatase that do not meet the criteria noted above. In these cases, the decision 
to proceed with additional evaluation will be made through consultation between the 
study investigators and the Sponsor Clinical Director. However, abnormalities of liver 
blood tests that do not meet the criteria noted above are not ECIs for this trial.
3. any suspected allergic reaction, including the following:

Any skin reaction, skin eruption, and/or rash occurrence in a study subject following 
administration of study drug. Skin lesions resulting from contact reactions to ECG 
lead adhesives and/or medical tape should be reported as AEs but do not need to be 
reported as ECI.

Study-drug related systemic reactions or study drug-related hypersensitivity reactions 
(e.g. anaphylaxis, angioedema)
Evaluating Adverse Events
7.2.4
An investigator who is a qualified physician will evaluate all adverse events with respect to 
the elements outlined in Table 9. The investigator’s assessment of causality is required for 
each adverse event.  Refer to Table 9 for instructions in evaluating adverse events.

Table 9
Evaluating Adverse Events
Maximum
Mild
awareness of sign or symptom, but easily tolerated  (for pediatric trials, awareness of symptom, but easily tolerated)
Intensity
Moderate
discomfort enough to cause interference with usual activity (for pediatric trials, definitely acting like something is wrong)
Severe
incapacitating with inability to work or do usual activity (for pediatric trials, extremely distressed or unable to do usual activities)
Seriousness
A serious adverse event (AE) is any adverse event occurring at any dose or during any use of Sponsor's product that:
†Results in death; or
†Is life threatening; or places the subject, in the view of the investigator, at immediate risk of death from the event as it occurred [Note: This does not include an 
adverse event  that, had it occurred in a more severe form, might have caused death.]; or
†Results in a persistent or significant disability/incapacity (substantial disruption of one’s ability to conduct normal life functions); or
†Results in or prolongs an existing inpatient hospitalization (hospitalization is defined as an inpatient admission, regardless of length of stay, even if the 
hospitalization is a precautionary measure for continued observation.  (Note: Hospitalization for an elective procedure to treat a pre-existing condition that has not 
worsened is not a serious adverse event.  A pre-existing condition is a clinical condition that is diagnosed prior to the use of a Merck product and is documented in the 
patient’s medical history.); or
†Is a congenital anomaly/birth defect  (in offspring of subject taking the product regardless of time to diagnosis); or
Is a cancer (although not serious per ICH definition, is reportable to the Sponsor within 24 hours to meet certain local requirements); or
Is associated with an overdose (whether accidental or intentional). Any adverse event associated with an overdose is considered a serious adverse event for 
collection purposes. An overdose that is not associated with an adverse event is considered a non-serious event of clinical interest and must be reported within 24 
hours.
Other important medical events that may not result in death, not be life threatening, or not require hospitalization may be considered a serious adverse event when, 
based upon appropriate medical judgment, the event may jeopardize the subject and may require medical or surgical intervention to prevent one of the outcomes listed 
previously (designated above by a †).
Duration
Record the start and stop dates of the adverse event.  If less than 1 day, indicate the appropriate length of time and units
Action taken 
Did the adverse event cause the Sponsor's product to be discontinued?
Relationship to 
Sponsor's 
Product
Did the Sponsor's product cause the adverse event? The determination of the likelihood that the Sponsor's product caused the adverse event will be provided by an 
investigator who is a qualified physician.  The investigator’s signed/dated initials on the source document or worksheet that supports the causality noted on the AE 
form, ensures that a medically qualified assessment of causality was done.  This initialed document must be retained for the required regulatory time frame.  The 
criteria below are intended as reference guidelines to assist the investigator in assessing the likelihood of a relationship between the test drug and the adverse event 
based upon the available information
The following components are to be used to assess the relationship between the Sponsor's product and the AE; the greater the correlation with the components 
and their respective elements (in number and/or intensity), the more likely the Sponsor's product caused the adverse event:
Exposure
Is there evidence that the subject was actually exposed to the Sponsor's product such as:  reliable history, acceptable compliance assessment (pill 
count, diary, etc.), expected pharmacologic effect, or measurement of drug/metabolite in bodily specimen?
Time Course
Did 
the 
AE 
follow 
in 
a 
reasonable 
temporal 
sequence 
from 
administration 
of 
the 
Sponsor's 
product? 
Is the time of onset of the AE compatible with a drug-induced effect (applies to trials with investigational medicinal product)?
Likely Cause
Is the AE not reasonably explained by another etiology such as underlying disease, other drug(s)/vaccine(s), or other host or environmental
factors

Product
(continued) 
Dechallenge
Was the Sponsor's product discontinued or dose/exposure/frequency reduced?
      If yes, did the AE resolve or improve?
           If yes, this is a positive dechallenge.    If no, this is a negative dechallenge.
(Note:  This criterion is not applicable if:  (1) the AE resulted in death or permanent disability; (2) the AE resolved/improved despite 
continuation of the Sponsor's product; (3) the trial is a single-dose drug trial); or (4) Sponsor's product(s) is/are only used one time.)
Rechallenge
Was the subject re-exposed to the Sponsor's product in this trial?
      If yes, did the AE recur or worsen?
          If yes, this is a positive rechallenge.    If no, this is a negative rechallenge.
(Note:  This criterion is not applicable if:  (1) the initial AE resulted in death or permanent disability, or (2) the trial is a single-dose drug trial); 
or (3) Sponsor's product(s) is/are used only one time.)
NOTE:  IF A RECHALLENGE IS PLANNED FOR AN ADVERSE EVENT WHICH WAS SERIOUS AND WHICH MAY HAVE BEEN 
CAUSED BY THE SPONSOR'S PRODUCT, OR IF RE-EXPOSURE TO THE SPONSOR'S PRODUCT POSES ADDITIONAL POTENTIAL 
SIGNIFICANT RISK TO THE SUBJECT THEN THE RECHALLENGE MUST BE APPROVED IN ADVANCE BY THE SPONSOR
CLINICAL DIRECTOR AND THE INSTITUTIONAL REVIEW BOARD/INDEPENDENT ETHICS COMMITTEE.
Consistency

Treatment 
Profile
Is the clinical/pathological presentation of the AE consistent with previous knowledge regarding the Sponsor's product or drug class 
pharmacology or toxicology?
The assessment of relationship will be reported on the case report forms /worksheets by an investigator who is a qualified physician according to his/her best clinical judgment, including 
consideration of the above elements.
Record one of the following:
Use the following scale of criteria as guidance (not all criteria must be present to be indicative of a Sponsor's product relationship).
Yes, there is a reasonable 
possibility of Sponsor's product 
relationship.
There is evidence of exposure to the Sponsor's product.  The temporal sequence of the AE onset relative to the administration of the Sponsor's 
product is reasonable.  The AE is more likely explained by the Sponsor's product than by another cause. 
No, there is not a reasonable 
possibility of Sponsor's product 
relationship
Subject did not receive the Sponsor's product OR temporal sequence of the AE onset relative to administration of the Sponsor's product is not 
reasonable OR the AE is more likely explained by another cause than the Sponsor’s product.  (Also entered for a subject with overdose without 
an associated AE.)

Guidelines for Good Clinical Practice.
8.0 STATISTICAL ANALYSIS PLAN
Statistical Analysis Plan Summary
8.1
This section contains a brief summary of the statistical analyses for this trial. Full details can 
be found beginning in Section 8.2.
Statistical Methods
Safety (All Study Parts):
Incidence of adverse experiences will be descriptively summarized. Summary statistics and 
plots will be generated for the change from baseline values in the vital signs, ECG 
parameters, and selected laboratory safety parameters for subjects, as deemed clinically 
appropriate. Depending on the safety parameter, the difference from baseline will either be 
computed on the original scale (raw change from baseline) or on the log scale and back-
transformed for reporting (percent change from baseline). Summary statistics for the raw 
laboratory safety tests, ECGs, and/or vital signs may also be computed, as deemed clinically 
appropriate.
Pharmacodynamics:
Individual maximal GIR values (GIRmax) during the clamp of MK-1092 SC or glargine SC
administered to adult subjects with T1DM based on LOESS smoothed data from Part 3 will 
be analyzed in a fixed effects model with treatment as fixed effect (i.e. glargine, MK-1092 
Dose Level 1, MK-1092 Dose Level 2, etc.).  Means and 95% confidence intervals of GIRmax
for each treatment/dose will be calculated from the model. Similar analysis (based on a 
slightly different model) will be done using data from Part 4 (T2DM). To test the Part 3
primary hypothesis, the posterior probability that the true mean GIR max level is within 1.5 
and 4.5 mg/kg/min will be calculated for each MK-1092 dose using a non-informative prior.  
If this posterior probability exceeds 70% for at least one safe and well tolerated dose of 
MK-1092 SC then the primary research hypothesis for Part 3 will be supported. There is no 
formal hypothesis testing (based on GIR) associated with Part 4. Posterior probabilities may 
be provided, if necessary.
Individual maximal GIR values (GIRmax) during the clamp in Part 1 will be determined based 
on LOESS smoothed data. Model based (similar to Part 3) statistics such as means, 95% 
confidence intervals etc. will be provided for each treatment/dose.

Pharmacokinetics (All Study Parts):
Geometric means and 95% confidence intervals will be provided for Cmax, AUC0-∞and 
CL/F, if calculated for the given study part, following SC administration by treatment.  
Individual values will be listed for each PK parameter by treatment and the additional 
following (non-model-based) descriptive statistics will be provided: N (number of subjects 
with non-missing data), arithmetic mean, standard deviation, arithmetic percent CV 
(calculated as 100 x standard deviation/arithmetic mean), median, minimum, maximum, 
geometric mean, and geometric percent CV (calculated as 100 x sqrt(exp(s2) - 1), where s2 is
the observed variance on the natural log-scale).  Median, minimum and maximum will only 
be provided for Tmax. 
The details for exploratory analyses can be found in Section 8.6.
Power
Pharmacodynamics (GIRmax):
The calculations in Table 10 below assume a between subject standard deviation of 0.44 for 
GIRmax, as was observed following SC administration of another IRPA (MK-5160) in healthy 
adult subjects. It is assumed that the variability of MK-1092 is similar to that of the other 
IRPA and that the variability in healthy adult subjects is similar to that in adult subjects with 
T1DM. The table below represents the probability of supporting the primary 
pharmacodynamics hypothesis under different assumed true mean of GIRmax values.

Responsibility for Analyses
8.2
The statistical analysis of the data obtained from this study will be conducted by, or under the 
direct auspices of, the Clinical Pharmacology Statistics Department in collaboration with the 
Quantitative Pharmacology and Pharmacometrics (QP2), and Translational Pharmacology 
Departments of the Sponsor.
If, after the study has begun, changes are made to the statistical analysis plan stated below, 
then these deviations to the plan will be listed, along with an explanation as to why they 
occurred, in the Clinical Study Report.
Hypotheses/Estimation
8.3
Hypothesis (Primary):  
(1) At a dose with sufficient safety, the mean GIRmax after single SC administration of 
MK-1092 in adult subjects with T1DM is between 1.5 and 4.5 mg/kg/min. (Part 3)
Analysis Endpoints
8.4
Primary:
Safety
The primary safety endpoints in this study will include all types of adverse events (AE), in 
addition to laboratory safety assessments, ECGs, and vital signs.
Pharmacodynamics
The primary pharmacodynamic variable in this study is the glucose infusion rate (GIR) 
required to maintain blood glucose at each subjects’ individual clamp target, following 
administration of MK-1092 SC or glargine SC.  To assess the primary hypothesis in Part 3, 
the maximal GIR (GIRmax) required to maintain the blood glucose target following 
administration of MK-1092 SC based on LOESS smoothed data during the euglycemic
clamp timeframe is of interest.
Secondary:
Pharmacokinetics
MK-1092 SC pharmacokinetic variables of interest include Cmax, AUC0-∞, CL/F, Tmax 
and apparent terminal t½ of. Similar variables for glargine are also of interest.

and 4 is a secondary endpoint. Specifically, GIRmax of MK-1092 SC or glargine SC during 
the euglycemic clamp timeframe are of interest in Parts 1 and 4.   
In addition, time-weighted average based on GIR [TWA(GIR): AUC(0-t) based on GIR 
values divided by time  (t); t= 24, 36 etc.] is also of interest.
Exploratory:
Pharmacodynamics
The glucose infusion rate (GIR) required to maintain blood glucose at each subjects’ 
individual clamp target following administration of MK-1092 SC after the start of Humalog
infusion in Part 2 is of interest. The GIRmax of MK-1092 after the start of Humalog infusion 
is of interest in Part 2.   
The exploratory pharmacodynamic endpoints in this study also include free fatty acids 
(FFA; also termed non-esterified fatty acids or NEFA), glycerol and ketones (e.g. 
β-hydroxybutyrate).   
Analysis Populations
8.5
The following populations are defined for the analysis and reporting of data. All subjects 
will be reported, and their data analyzed, according to the treatment(s) they actually received.
All Subjects as Treated (AST) – All subjects who received at least one dose of the 
investigational drug. This population will be used for assessments of safety and tolerability.
Per-Protocol (PP) – The set of data generated by the subset of subjects who comply with the 
protocol sufficiently to ensure that these data will be likely to exhibit the effects of treatment, 
according to the underlying scientific model. Compliance covers such considerations as 
exposure to treatment, availability of measurements and absence of major protocol 
deviations.  Major protocol deviators will be identified to the extent possible prior to 
unblinding by individuals responsible for data collection/compliance, and its analysis
and interpretation. Any subjects or data values excluded from analysis will be identified,
along with their reason for exclusion, in the CSR. At the end of the study, all subjects
who are compliant with the study procedure as aforementioned and have available data
from at least one treatment will be included in the primary analysis dataset. This population
will be used for the PK and PD analyses.
Statistical Methods

Primary
Safety (All Study Parts):
Incidence of adverse experiences will be descriptively summarized. Summary statistics and

appropriate.  Depending on the safety parameter, the difference from baseline will either be 
computed on the original scale (raw change from baseline) or on the log scale and back-
transformed for reporting (percent change from baseline).  Summary statistics for the raw 
laboratory safety tests, ECGs, and/or vital signs may also be computed, as deemed clinically 
appropriate.
Pharmacodynamics:
GIR (Part 3)
Individual maximal GIRmax during the euglycemic clamp timeframe following MK-1092 
SC or glargine SC administered to adult subjects with T1DM based on LOESS smoothed 
data from Part 3 will be analyzed in a fixed effects model with an effect for treatment (i.e. 
glargine dose, MK-1092 Dose Level 1, MK-1092 Dose Level 2, etc).  Means and 95% 
confidence intervals of GIRmax for each treatment/dose will be calculated from the model.  
To test the Part 3 primary hypothesis, the posterior probability that the true mean GIRmax
level is within 1.5 and 4.5 mg/kg/min will be calculated for each MK-1092 dose using a 
non-informative prior.  If this posterior probability exceeds 70% for at least one safe and 
well tolerated dose of MK-1092 SC then the primary research hypothesis for Part 3 will be 
supported. 
Additionally, a non-linear mixed effects model-based analysis may be used to assess the 
PK/PD (i.e. concentration/GIR) relationship.  The model for MK-1092 will be developed 
using data from Part 3.  The model for glargine will be developed using data from Part 3 of 
the current study and available historical data.
Secondary
Pharmacodynamics:
GIR (Parts 1 & 4):
Individual maximal GIR values (GIRmax) during the clamp in Part 1 and Part 4 will be 
smoothed based on LOESS method. 
Model based (similar to Part 3: fixed effect model) statistics such as means, 95% confidence 
intervals etc. will be provided for each treatment/dose in Part 1.
For Part 4, a linear mixed effects model containing a fixed effect for treatment (MK-1092, 
Glargine), a nested effect from subjects within treatment (subjects within treatment), an 
interaction between treatment and period (treatment by period: Period = Period 1, 2, 3) and a 
random effect due to subjects will be used. Kenward and Roger's method will be used to 
calculate the denominator degrees of freedom for the fixed effects. Model based statistics 
such as means, 95% confidence intervals etc. will be provided for each treatment/dose.
TWA(GIR) (Part 1, 3 and 4):
Time-weighted average based on GIR [TWA(GIR): AUC(0-t) based on GIR values divided 
by time  (t)] is also of interest. Model based (similar to GIRmax in Part 3) statistics such as

General:
For all analyses, data will be examined for departures from the assumptions of the statistical 
model(s) as appropriate; e.g., heteroscedasticity, nonnormality of the error terms.  
Distribution-free methods may be used if a serious departure from the assumptions of the 
models(s) is observed, or suitable data transformations may be applied.
Multiplicity
8.7
Formal statistical testing with associated p-value cut-offs centered around controlling Type-I 
error rates will not be used in assessing the hypotheses; hence no multiplicity adjustment is 
required or proposed.
Sample Size and Power Calculations
8.8
Pharmacodynamics (GIRmax):
The calculations in Table 11 below assume a between subject standard deviation of 0.44 for 
GIRmax, as was observed following SC administration of another IRPA (MK-5160) in healthy 
adult subjects.  It is assumed that the variability of MK-1092 is similar to that of the other 
IRPA and that the variability in healthy adult subjects is similar to that in adult subjects with 
T1DM. The table below represents the probability of supporting the primary 
pharmacodynamics hypothesis under different assumed true mean of GIRmax values.

Compliance with Law, Audit and Debarment
10.3
By signing this protocol, the investigator agrees to conduct the trial in an efficient and 
diligent manner and in conformance with this protocol; generally accepted standards of Good 
Clinical Practice (e.g., International Conference on Harmonization of Technical 
Requirements for Registration of Pharmaceuticals for Human Use Good Clinical Practice: 
Consolidated Guideline and other generally accepted standards of good clinical practice); and 
all applicable federal, state and local laws, rules and regulations relating to the conduct of the 
clinical trial.
The Code of Conduct, a collection of goals and considerations that govern the ethical and 
scientific conduct of clinical investigations sponsored by Merck, is provided in Section 12.1 -
Merck Code of Conduct for Clinical Trials.
The investigator also agrees to allow monitoring, audits, IRB/IEC review and regulatory 
authority inspection of trial-related documents and procedures and provide for direct access 
to all trial-related source data and documents.
The investigator agrees not to seek reimbursement from subjects, their insurance providers or 
from government programs for procedures included as part of the trial reimbursed to the 
investigator by the Sponsor.
The investigator shall prepare and maintain complete and accurate trial documentation in 
compliance with Good Clinical Practice standards and applicable federal, state and local 
laws, rules and regulations; and, for each subject participating in the trial, provide all data, 
and, upon completion or termination of the clinical trial, submit any other reports to the 
Sponsor as required by this protocol or as otherwise required pursuant to any agreement with 
the Sponsor.

advertising for subject participation, adverse event reports, subject source data, 
correspondence with regulatory authorities and IRBs/ERCs, consent forms, investigator’s 
curricula vitae, monitor visit logs, laboratory reference ranges, laboratory certification or 
quality control procedures and laboratory director curriculum vitae.  By signing this protocol, 
the investigator agrees that documentation shall be retained until at least 2 years after the last 
approval of a marketing application in an ICH region or until there are no pending or 
contemplated marketing applications in an ICH region or until at least 2 years have elapsed 
since the formal discontinuation of clinical development of the investigational product.  
Because the clinical development and marketing application process is variable, it is 
anticipated that the retention period can be up to 15 years or longer after protocol database 
lock. The Sponsor will determine the minimum retention period and notify the investigator 
when documents may be destroyed.  The Sponsor will determine the minimum retention 
period and upon request, will provide guidance to the investigator when documents no longer 
need to be retained.  The Sponsor also recognizes that documents may need to be retained for 
a longer period if required by local regulatory requirements. All trial documents shall be 
made available if required by relevant regulatory authorities. The investigator must consult 
with and obtain written approval by the Sponsor prior to destroying trial and/or subject files.  
ICH Good Clinical Practice guidelines recommend that the investigator inform the subject’s 
primary physician about the subject’s participation in the trial if the subject has a primary 
physician and if the subject agrees to the primary physician being informed.
The investigator will promptly inform the Sponsor of any regulatory authority inspection 
conducted for this trial.
Persons debarred from conducting or working on clinical trials by any court or regulatory 
authority will not be allowed to conduct or work on this Sponsor’s trials.  The investigator 
will immediately disclose in writing to the Sponsor if any person who is involved in 
conducting the trial is debarred or if any proceeding for debarment is pending or, to the best 
of the investigator’s knowledge, threatened.
In the event the Sponsor prematurely terminates a particular trial site, the Sponsor will 
promptly notify that trial site’s IRB/IEC.
According to European legislation, a Sponsor must designate an overall coordinating 
investigator for a multi-center trial (including multinational).  When more than one trial site 
is open in an EU country, Merck, as the Sponsor, will designate, per country, a national 
principal coordinator (Protocol CI), responsible for coordinating the work of the principal 
investigators at the different trial sites in that Member State, according to national 
regulations.  For a single-center trial, the Protocol CI is the principal investigator.  In 
addition, the Sponsor must designate a principal or coordinating investigator to review the 
trial report that summarizes the trial results and confirm that, to the best of his/her 
knowledge, the report accurately describes the conduct and results of the trial [Clinical Study 
Report (CSR) CI].  The Sponsor may consider one or more factors in the selection of the 
individual to serve as the Protocol CI and or CSR CI (e.g., availability of the Protocol/CSR 
CI during the anticipated review process, thorough understanding of clinical trial methods, 
appropriate enrollment of subject cohort, timely achievement of trial milestones).  The 
Protocol CI must be a participating trial investigator.

Compliance with Trial Registration and Results Posting Requirements
10.4
Under the terms of the Food and Drug Administration Amendments Act (FDAAA) of 2007 
and the European Medicines Agency (EMA) clinical trial Directive 2001/20/EC, the Sponsor 
of the trial is solely responsible for determining whether the trial and its results are subject to 
the 
requirements 
for 
submission 
to 
http://www.clinicaltrials.gov, 
www.clinicaltrialsregister.eu or other local registries.  Merck, as Sponsor of this trial, will 
review this protocol and submit the information necessary to fulfill these requirements. 
Merck entries are not limited to FDAAA or the EMA clinical trial directive mandated trials.  
Information posted will allow subjects to identify potentially appropriate trials for their 
disease conditions and pursue participation by calling a central contact number for further 
information on appropriate trial locations and trial site contact information.  
By signing this protocol, the investigator acknowledges that the statutory obligations under 
FDAAA, the EMA clinical trials directive or other locally mandated registries are that of the 
Sponsor and agrees not to submit any information about this trial or its results to those 
registries.
Quality Management System
10.5
By signing this protocol, the Sponsor agrees to be responsible for implementing and 
maintaining a quality management system with written development procedures and 
functional area standard operating procedures (SOPs) to ensure that trials are conducted and 
data are generated, documented, and reported in compliance with the protocol, accepted 
standards of Good Clinical Practice, and all applicable federal, state, and local laws, rules and 
regulations relating to the conduct of the clinical trial.
Data Management
10.6
The investigator or qualified designee is responsible for recording and verifying the accuracy 
of subject data.  By signing this protocol, the investigator acknowledges that his/her 
electronic signature is the legally binding equivalent of a written signature.  By entering 
his/her electronic signature, the investigator confirms that all recorded data have been 
verified as accurate.
Detailed information regarding Data Management procedures for this protocol will be 
provided separately.
Publications
10.7
This trial is intended for publication, even if terminated prematurely. Publication may include 
any or all of the following: posting of a synopsis online, abstract and/or presentation at a 
scientific conference, or publication of a full manuscript.  The Sponsor will work with the 
authors to submit a manuscript describing trial results within 12 months after the last data 
become available, which may take up to several months after the last subject visit in some 
cases such as vaccine trials.  However, manuscript submission timelines may be extended on 
OTC trials.  For trials intended for pediatric-related regulatory filings, the investigator agrees

to delay publication of the trial results until the Sponsor notifies the investigator that all 
relevant regulatory authority decisions on the trial drug have been made with regard to 
pediatric-related regulatory filings. Merck will post a synopsis of trial results for approved 
products on www.clinicaltrials.gov by 12 months after the last subject's last visit for the
primary outcome, 12 months after the decision to discontinue development, or product 
marketing (dispensed, administered, delivered or promoted), whichever is later.
These timelines may be extended for products that are not yet marketed, if additional time is 
needed for analysis, to protect intellectual property, or to comply with confidentiality 
agreements with other parties.  Authors of the primary results manuscript will be provided 
the complete results from the Clinical Study Report, subject to the confidentiality agreement. 
When a manuscript is submitted to a biomedical journal, the Sponsor's policy is to also 
include the protocol and statistical analysis plan to facilitate the peer and editorial review of 
the manuscript.  If the manuscript is subsequently accepted for publication, the Sponsor will 
allow the journal, if it so desires, to post on its website the key sections of the protocol that 
are relevant to evaluating the trial, specifically those sections describing the trial objectives 
and hypotheses, the subject inclusion and exclusion criteria, the trial design and procedures, 
the efficacy and safety measures, the statistical analysis plan, and any amendments relating to 
those sections.  The Sponsor reserves the right to redact proprietary information.
For multicenter trials, subsequent to the multicenter publication (or after public disclosure of 
the results online at www.clinicaltrials.gov if a multicenter manuscript is not planned), an 
investigator and his/her colleagues may publish their data independently.  In most cases, 
publication of individual trial site data does not add value to complete multicenter results, 
due to statistical concerns.  In rare cases, publication of single trial site data prior to the main 
paper may be of value.  Limitations of single trial site observations in a multicenter trial 
should always be described in such a manuscript.
Authorship credit should be based on 1) substantial contributions to conception and design, 
or acquisition of data, or analysis and interpretation of data; 2) drafting the article or revising 
it critically for important intellectual content; and 3) final approval of the version to be 
published. Authors must meet conditions 1, 2 and 3.  Significant contributions to trial 
execution may also be taken into account to determine authorship, provided that 
contributions have also been made to all three of the preceding authorship criteria.  Although 
publication planning may begin before conducting the trial, final decisions on authorship and 
the order of authors’ names will be made based on participation and actual contributions to 
the trial and writing, as discussed above. The first author is responsible for defending the 
integrity of the data, method(s) of data analysis and the scientific content of the manuscript.
The Sponsor must have the opportunity to review all proposed abstracts, manuscripts or 
presentations regarding this trial 45 days prior to submission for publication/presentation. 
Any information identified by the Sponsor as confidential must be deleted prior to 
submission; this confidentiality does not include efficacy and safety results. Sponsor review 
can be expedited to meet publication timelines.

12.0 APPENDICES
Merck Code of Conduct for Clinical Trials
12.1
Merck*
Code of Conduct for Clinical Trials
I.
Introduction
A. Purpose
Merck, through its subsidiaries, conducts clinical trials worldwide to evaluate the safety and effectiveness of our 
products. As such, we are committed to designing, implementing, conducting, analyzing and reporting these trials in 
compliance with the highest ethical and scientific standards. Protection of subject safety is the overriding concern in 
the design of clinical trials. In all cases, Merck clinical trials will be conducted in compliance with local and/or 
national regulations and in accordance with the ethical principles that have their origin in the Declaration of Helsinki. 
B. Scope
Such standards shall be endorsed for all clinical interventional investigations sponsored by Merck irrespective of the 
party (parties) employed for their execution (e.g., contract research organizations, collaborative research efforts). This 
Code is not intended to apply to trials which are observational in nature, or which are retrospective. Further, this Code 
does not apply to investigator-initiated trials which are not under the control of Merck.
II. Scientific Issues
A. Trial Conduct
1. Trial Design
Except for pilot or estimation trials, clinical trial protocols will be hypothesis-driven to assess safety, efficacy 
and/or pharmacokinetic or pharmacodynamic indices of Merck or comparator products.  Alternatively, Merck may 
conduct outcomes research trials, trials to assess or validate various endpoint measures, or trials to determine 
subject preferences, etc.  
The design (i.e., subject population, duration, statistical power) must be adequate to address the specific purpose 
of the trial.  Research subjects must meet protocol entry criteria to be enrolled in the trial. 
2. Site Selection
Merck selects investigative sites based on medical expertise, access to appropriate subjects, adequacy of facilities 
and staff, previous performance in Merck trials, as well as budgetary considerations.  Prior to trial initiation, sites 
are evaluated by Merck personnel to assess the ability to successfully conduct the trial.
3. Site Monitoring/Scientific Integrity
Trial sites are monitored to assess compliance with the trial protocol and general principles of Good Clinical 
Practice.  Merck reviews clinical data for accuracy, completeness and consistency. Data are verified versus source 
documentation according to standard operating procedures.  Per Merck policies and procedures, if fraud, 
misconduct or serious GCP-non-Compliance are suspected, the issues are promptly investigated. When necessary, 
the clinical site will be closed, the responsible regulatory authorities and ethics review committees notified and 
data disclosed accordingly. 
B. Publication and Authorship
To the extent scientifically appropriate, Merck seeks to publish the results of trials it conducts.  Some early phase or 
pilot trials are intended to be hypothesis-generating rather than hypothesis testing.  In such cases, publication of 
results may not be appropriate since the trial may be underpowered and the analyses complicated by statistical issues 
of multiplicity.
Merck’s policy on authorship is consistent with the requirements outlined in the ICH-Good Clinical Practice 
guidelines. In summary, authorship should reflect significant contribution to the design and conduct of the trial, 
performance or interpretation of the analysis, and/or writing of the manuscript.  All named authors must be able to 
defend the trial results and conclusions.  Merck funding of a trial will be acknowledged in publications.

III. Subject Protection
A. IRB/ERC review
All clinical trials will be reviewed and approved by an independent IRB/ERC before being initiated at each site.  
Significant changes or revisions to the protocol will be approved by the IRB/ERC prior to implementation, except that 
changes required urgently to protect subject safety and well-being may be enacted in anticipation of IRB/ERC 
approval. For each site, the IRB/ERC and Merck will approve the subject informed consent form. 
B. Safety
The guiding principle in decision-making in clinical trials is that subject welfare is of primary importance.  Potential 
subjects will be informed of the risks and benefits of, as well as alternatives to, trial participation. At a minimum, trial 
designs will take into account the local standard of care.  Subjects are never denied access to appropriate medical care 
based on participation in a Merck clinical trial. 
All participation in Merck clinical trials is voluntary.  Subjects are enrolled only after providing informed consent for 
participation.  Subjects may withdraw from a Merck trial at any time, without any influence on their access to, or 
receipt of, medical care that may otherwise be available to them.
C. Confidentiality
Merck is committed to safeguarding subject confidentiality, to the greatest extent possible.  Unless required by law,
only the investigator, Sponsor (or representative) and/or regulatory authorities will have access to confidential medical 
records that might identify the research subject by name.  
D. Genomic Research
Genomic Research will only be conducted in accordance with informed consent and/or as specifically authorized by 
an Ethics Committee.
IV. Financial Considerations
A. Payments to Investigators
Clinical trials are time- and labor-intensive.  It is Merck’s policy to compensate investigators (or the sponsoring 
institution) in a fair manner for the work performed in support of Merck trials.  Merck does not pay incentives to 
enroll subjects in its trials.  However, when enrollment is particularly challenging, additional payments may be made 
to compensate for the time spent in extra recruiting efforts.
Merck does not pay for subject referrals.  However, Merck may compensate referring physicians for time spent on 
chart review to identify potentially eligible subjects.
B. Clinical Research Funding 
Informed consent forms will disclose that the trial is sponsored by Merck, and that the investigator or sponsoring 
institution is being paid or provided a grant for performing the trial.  However, the local IRB/ERC may wish to alter 
the wording of the disclosure statement to be consistent with financial practices at that institution.  As noted above, 
publications resulting from Merck trials will indicate Merck as a source of funding.
C. Funding for Travel and Other Requests
Funding of travel by investigators and support staff (e.g., to scientific meetings, investigator meetings, etc.) will be 
consistent with local guidelines and practices including, in the U.S., those established by the American Medical 
Association (AMA). 
V. Investigator Commitment
Investigators will be expected to review Merck’s Code of Conduct as an appendix to the trial protocol, and in signing 
the protocol, agree to support these ethical and scientific standards.

Collection and Management of Specimens for Future Biomedical Research
12.2
1. Definitions
a.
Biomarker:  A biological molecule found in blood, other body fluids, or tissues that is a 
sign of a normal or abnormal process or of a condition or disease.  A biomarker may be 
used to see how well the body responds to a treatment for a disease or condition.1
b. Pharmacogenomics:  The investigation of variations of DNA and RNA characteristics as 
related to drug/vaccine response.2
c.
Pharmacogenetics:  A subset of pharmacogenomics, pharmacogenetics is the influence of
variations in DNA sequence on drug/vaccine response.2
d. DNA:  Deoxyribonucleic acid.
e.
RNA:  Ribonucleic acid.
2. Scope of Future Biomedical Research
The specimens consented and/or collected in this trial as outlined in Section 7.1.3.4 –
Future Biomedical Research Samples will be used in various experiments to understand:
o
The biology of how drugs/vaccines work
o
Biomarkers responsible for how a drug/vaccine enters and is removed by the body
o
Other pathways drugs/vaccines may interact with
o
The biology of disease
The specimen(s) may be used for future assay development and/or drug/vaccine 
development.
It is now well recognized that information obtained from studying and testing clinical 
specimens offers unique opportunities to enhance our understanding of how individuals 
respond to drugs/vaccines, enhance our understanding of human disease and ultimately 
improve public health through development of novel treatments targeted to populations 
with the greatest need.  All specimens will be used by the Sponsor or those working for 
or with the Sponsor.
3. Summary of Procedures for Future Biomedical Research
a.
Subjects for Enrollment
All subjects enrolled in the clinical trial will be considered for enrollment in the 
Future Biomedical Research sub-trial.
b. Informed Consent
Informed consent for specimens (i.e., DNA, RNA, protein, etc.) will be obtained 
during screening for protocol enrollment from all subjects or legal guardians, at a trial 
visit by the investigator or his or her designate.  Informed consent for Future 
Biomedical Research should be presented to the subjects on the visit designated in the 
trial flow chart.  If delayed, present consent at next possible Subject Visit.  Consent 
forms signed by the subject will be kept at the clinical trial site under secure storage 
for regulatory reasons.

A template of each trial site’s approved informed consent will be stored in the 
Sponsor’s clinical document repository.
c.
eCRF Documentation for Future Biomedical Research Specimens
Documentation of subject consent for Future Biomedical Research will be captured in 
the electronic Case Report Forms (eCRFs). Any specimens for which such an 
informed consent cannot be verified will be destroyed.
d. Future Biomedical Research Specimen(s)
Collection of specimens for Future Biomedical Research will be performed as 
outlined in the trial flow chart. In general, if additional blood specimens are being 
collected for Future Biomedical Research, these will usually be obtained at a time 
when the subject is having blood drawn for other trial purposes.
4. Confidential Subject Information for Future Biomedical Research 
In order to optimize the research that can be conducted with Future Biomedical Research 
specimens, it is critical to link subject' clinical information with future test results. In fact 
little or no research can be conducted without connecting the clinical trial data to the 
specimen. The clinical data allow specific analyses to be conducted. Knowing subject 
characteristics like gender, age, medical history and treatment outcomes are critical to 
understanding clinical context of analytical results.
To maintain privacy of information collected from specimens obtained for Future 
Biomedical Research, the Sponsor has developed secure policies and procedures. All 
specimens will be single-coded per ICH E15 guidelines as described below. 
At the clinical trial site, unique codes will be placed on the Future Biomedical Research 
specimens.  This code is a random number which does not contain any personally 
identifying information embedded within it. The link (or key) between subject identifiers 
and this unique code will be held at the trial site.  No personal identifiers will appear on 
the specimen tube.  
5. Biorepository Specimen Usage
Specimens obtained for the Sponsor will be used for analyses using good scientific 
practices.  Analyses utilizing the Future Biomedical Research specimens may be 
performed by the Sponsor, or an additional third party (e.g., a university investigator) 
designated by the Sponsor. The investigator conducting the analysis will follow the 
Sponsor’s privacy and confidentiality requirements. Any contracted third party analyses 
will conform to the specific scope of analysis outlined in this sub-trial. Future Biomedical 
Research specimens remaining with the third party after specific analysis is performed 
will be reported to the Sponsor.
6. Withdrawal From Future Biomedical Research 
Subjects may withdraw their consent for Future Biomedical Research and ask that their 
biospecimens not be used for Future Biomedical Research.  Subjects may withdraw 
consent at any time by contacting the principal investigator for the main trial. If medical 
records for the main trial are still available, the investigator will contact the Sponsor 
using 
the 
designated 
mailbox 
(clinical.specimen.management@merck.com).

Subsequently, the subject's specimens will be flagged in the biorepository and restricted 
to main study use only. If specimens were collected from study participants specifically 
for Future Biomedical Research, these specimens will be removed from the biorepository 
and destroyed. Documentation will be sent to the investigator confirming withdrawal 
and/or destruction, if applicable. It is the responsibility of the investigator to inform the 
subject of completion of the withdrawal and/or destruction, if applicable.  Any analyses 
in progress at the time of request for withdrawal/destruction or already performed prior to 
the request being received by the Sponsor will continue to be used as part of the overall 
research trial data and results. No new analyses would be generated after the request is 
received.
In the event that the medical records for the main trial are no longer available (e.g., if the 
investigator is no longer required by regulatory authorities to retain the main trial 
records) or the specimens have been completely anonymized, there will no longer be a 
link between the subject’s personal information and their specimens. In this situation, the 
request for withdrawal of consent and/or destruction cannot be processed.
7. Retention of Specimens 
Future Biomedical Research specimens will be stored in the biorepository for potential 
analysis for up to 20 years from the end of the main study. Specimens may be stored for 
longer if a regulatory or governmental authority has active questions that are being 
answered. In this special circumstance, specimens will be stored until these questions 
have been adequately addressed.
Specimens from the trial site will be shipped to a central laboratory and then shipped to 
the Sponsor-designated biorepository. If a central laboratory is not utilized in a particular 
trial, the trial site will ship directly to the Sponsor-designated biorepository. The 
specimens will be stored under strict supervision in a limited access facility which 
operates to assure the integrity of the specimens.  Specimens will be destroyed according 
to Sponsor policies and procedures and this destruction will be documented in the 
biorepository database.
8. Data Security
Databases containing specimen information and test results are accessible only to the 
authorized Sponsor representatives and the designated trial administrator research 
personnel and/or collaborators. Database user authentication is highly secure, and is 
accomplished using network security policies and practices based on international 
standards to protect against unauthorized access.
9. Reporting of Future Biomedical Research Data to Subjects
No information obtained from exploratory laboratory studies will be reported to the 
subject, family, or physicians. Principle reasons not to inform or return results to the 
subject include: Lack of relevance to subject health, limitations of predictive capability, 
and concerns regarding misinterpretation.
If important research findings are discovered, the Sponsor may publish results, present 
results in national meetings, and make results accessible on a public website in order to 
rapidly report this information to doctors and subjects.  Subjects will not be identified by

presentation.
10. Future Biomedical Research Study Population
Every effort will be made to recruit all subjects diagnosed and treated on Sponsor clinical 
trials for Future Biomedical Research.
11. Risks Versus Benefits of Future Biomedical Research 
For future biomedical research, risks to the subject have been minimized. No additional 
risks to the subject have been identified as no additional specimens are being collected 
for Future Biomedical Research (i.e., only leftover samples are being retained).
The Sponsor has developed strict security, policies and procedures to address subject data 
privacy concerns.  Data privacy risks are largely limited to rare situations involving 
possible breach of confidentiality.  In this highly unlikely situation there is risk that the 
information, like all medical information, may be misused.
12. Questions
Any questions related to the future biomedical research should be e-mailed directly to

a Abnormalities noted, but not considered clinically significant should be discussed with Sponsor to determine whether the 
individual may be included in the study.
b Post-randomization assessments are at each specified timepoint. Discussion between the investigator and sponsor should 
occur if abnormalities are noted.
QTc Stopping Criteria:
1. Confirmed increase in absolute QTc ≥500 ms 
If the QTc interval is 500 msec, the Sponsor should be notified and the ECGs should be 
reviewed by a cardiologist. The subject should be telemetry-monitored (until the QTc is <500 
msec) or should be considered for transfer to a location where closer monitoring and 
definitive care (e.g., a Cardiac or Intensive Care Unit) is available.
2. Confirmed increase in QTc from baseline of ≥60 ms
During each treatment period, if a subject demonstrates an increase in QTc interval ≥60 
msec compared with median predose baseline measurement, the ECG will be repeated twice 
within 5 minutes.  The median value of the QTc interval from the 3 ECGs will represent the 
value at that time point.  If the QTc interval increase from baseline for any postdose time 
point is ≥60 msec, the subject will continue to be monitored by repeat 12-lead ECGs every 
15 minutes for at least 1 hour or until the QTc is within 60 msec of baseline.  If prolongation 
of the QTc interval ≥60 msec persists, a consultation with a study cardiologist may be 
appropriate and the Sponsor should be notified.

Algorithm for Assessing Out-of-Range Laboratory Values
12.5
For all laboratory values obtained at prestudy (screening) visit and/or pre-dose evaluation:
A. If all protocol-specified laboratory values are normal, the subject may enter the study.
B. If a protocol specified laboratory value is outside of the parameter(s) outlined in the 
inclusion/exclusion criteria (including a repeat if performed), the subject will be excluded 
from the study.
C. If ≥1 protocol-specified laboratory value not specified in the inclusion/exclusion criteria 
is outside the normal range, the following choices are available:
1. The subject may be excluded from the study;
2. The subject may be included in the study if the abnormal value(s) is not clinically 
significant (NCS) (the investigator must annotate the laboratory value “NCS” on the 
laboratory safety test source document).
3. The subject may be included in the study if the abnormality is consistent with a pre-
existing medical condition which is not excluded per protocol (e.g., elevated 
eosinophil count in a subject with asthma or seasonal allergies) the medical condition 
should be annotated on the laboratory report or
4. The abnormal test may be repeated (refer items a. and b. below for continuation of 
algorithm for repeated values).
a.
If the repeat test value is within the normal range, the subject may enter the study.
b. If the repeat test value is still abnormal, the study investigator will evaluate the 
potential subject with a complete history and physical examination, looking 
especially for diseases that could result in the abnormal laboratory value in 
question.  If such diseases can be ruled out, and if the abnormal laboratory value 
is not clinically relevant, then the subject may enter the study.
D. If there is any clinical uncertainty regarding the significance of an abnormal value, the 
subject will be excluded from the study.

The following will be used to determine adverse event (AE) reporting in cases of 
hypoglycemia and hyperglycemia:
Hypoglycemia is defined as glucose values ≤70 mg/dL with symptoms and glucose values   
≤50 mg/dL with or without symptoms. Fingerstick measurements (as opposed to CGM) 
should be used when possible to assess a potential hypoglycemia AE.

If there are symptoms associated with low glucose (≤70 mg/dL), this is a clinical AE
with a diagnosis of hypoglycemia. 

If there are no symptoms associated with a low glucose (> 50 mg/dL ≤70 mg/dL) it is 
up to the investigator to decide if this is a laboratory AE.  The AE would be 
decreased glucose, not hypoglycemia.

All glucose values ≤70 mg/dL will require a comment that states whether or not there 
were associated symptoms of hypoglycemia.
Hyperglycemia: 
If there are symptoms associated with a high glucose, this is a clinical AE with a diagnosis 
of hyperglycemia. Fingerstick measurements (as opposed to CGM) should be used when 
possible to assess a potential hyperglycemia AE.

Fingerstick glucose assessment can be performed at any time, at the discretion of the 
Investigator.
Correction of hyper-/hypoglycemia should be initiated as appropriate, at the discretion of the 
Investigator according to the site’s standard operating procedures.  Corrective actions for 
hypoglycemia include, but are not limited to: offering food/drink, IV dextrose bolus, and 
initiating or increasing the rate of a running IV dextrose infusion.  Corrective actions for 
hyperglycemia include, but are not limited to: bolus SC injection of short-acting insulin via 
insulin pump or injection, initiation or increase in the rate of a SC infusion of short-acting 
insulin via insulin pump, and initiation or increase in the rate of an IV infusion of insulin.  
The dose and/or frequency of MK-1092/comparator insulin (glargine) should not be changed 
for hyperglycemia.
