SYNOPSIS 
Compound: 
MK-3866 
Clinical Indication: 
Treatment of gram-negative bacterial infections 
Study Phase and Type: 
Phase 1 - Interventional 
Study Objectives and 
Estimations: 
Primary: 
Objective 1:  To compare the plasma pharmacokinetics (e.g., 
AUC0-∞, AUC0-last, AUC0-24, Ceoi (Cmax), Tmax, 
elimination terminal t½, CL, and Vz) of MK-3866 following a 
single intravenous (IV) dose in subjects with mild renal 
impairment (RI) to those of mean healthy matched control 
subjects. 
Estimation 1:  The AUC0-∞ following a single IV dose of 
MK-3866 administered to subjects with mild RI will be 
estimated and compared to the AUC0-∞ when administered to 
mean healthy matched control subjects. 
Objective 2:  To compare the plasma pharmacokinetics (e.g., 
AUC0-∞, AUC0-last, AUC0-24, Ceoi (Cmax), Tmax, 
elimination terminal t½, CL, and Vz) of MK-3866 following a 
single IV dose in subjects with moderate RI to those of mean 
healthy matched control subjects. 
Estimation 2:  The AUC0-∞ following a single IV dose of 
MK-3866 administered to subjects with moderate RI will be 
estimated and compared to the AUC0-∞ when administered to 
mean healthy matched control subjects. 
Objective 3:  To compare the plasma pharmacokinetics (e.g., 
AUC0-∞, AUC0-last, AUC0-24, Ceoi (Cmax), Tmax, 
elimination terminal t½, CL, and Vz) of MK-3866 following a 
single IV dose in subjects with severe RI to those of healthy 
matched control subjects. 
Estimation 3:  The AUC0-∞ following a single IV dose of 
MK-3866 administered to subjects with severe RI will be 
estimated and compared to the AUC0-∞ when administered to 
mean healthy matched control subjects. 
Objective 4:  To compare the plasma pharmacokinetics (e.g., 
AUC0-∞, AUC0-last, AUC0-24, Ceoi (Cmax), Tmax, 
elimination terminal t½, CL, and Vz) of MK-3866 following a 
single IV dose administered after hemodialysis (HD) in subjects

with end stage renal disease (ESRD) undergoing HD to those of 
mean healthy matched control subjects. 
Estimation 4:  The AUC0-∞ following a single IV dose of 
MK-3866 administered after HD to subjects with ESRD will be 
estimated and compared to the AUC0-∞ when administered to 
mean healthy matched control subjects. 
Objective 5:  To compare the plasma pharmacokinetics (e.g., 
AUC0-∞, AUC0-last, AUC0-24, Ceoi (Cmax), Tmax, 
elimination terminal t½, CL, and Vz) of MK-3866 following a 
single IV dose administered prior to HD in subjects with ESRD 
to those of mean healthy matched control subjects. 
Estimation 5:  The AUC0-∞ following a single IV dose of 
MK-3866 administered prior to HD to subjects with ESRD will 
be estimated and compared to the AUC0-∞ when administered 
to mean healthy matched control subjects. 
Secondary: 
Objective 1:  To investigate the extent to which MK-3866 is 
removed by HD.  
Estimation 1:  The extent to which MK-3866 is removed by HD 
from the plasma (e.g., Ca, Cv, AUCD, AUC[1-4.5]Ca, 
AUC[1-4.5]Cv, and CLD,plasma) or the dialysate (e.g., CD, AD, 
rr, AD,total, and CLD,dialysate) will be estimated. 
Objective 2:  To compare the urine pharmacokinetics (e.g., 
Ae0-24, Fe, and CLr) of MK-3866 following a single IV dose of 
MK-3866 to subjects with varying degrees of RI, where possible, 
to those of healthy matched control subjects. 
Estimation 2:  The Ae0-24, Fe, and CLr following a single IV 
dose of MK-3866 administered to subjects with varying degrees 
of RI will be estimated and compared to those estimated in mean 
healthy matched control subjects. 
Objective 3:  To evaluate the safety and tolerability of the 
administration of a single IV dose of MK-3866 in subjects with 
varying degrees of RI. 
Exploratory Objective: 
Objective:  To explore the relationship between eGFR and 
pharmacokinetics (e.g. CLr and AUC0-∞) of MK-3866 using a 
model-based approach.

Planned Exploratory Biomarker: 
Objective:  To explore the relationship between genetic variation 
and response to the treatment(s) administered, and mechanisms 
of disease. Variation across the human genome may be analyzed 
for association with clinical data collected in this study. 
Summary of Study 
Design: 
This is an open-label, 2-part, single dose study in renal impaired 
and healthy control subjects. Parts 1 and 2 of the study may be 
conducted concurrently. 
Study parts and assignment to a renal function group will be as 
follows: 
 
Panel 
Renal Function 
N 
eGFR 
(mL/min/1.73m2)* 
Part 1 
A 
Mild 
8 
60 ≤ eGFR< 90 
B 
Moderate 
8 
30 ≤ eGFR < 60** 
C 
Severe 
8 
< 30 not on 
dialysis 
D 
Healthy 
Matched Control 
≥ 8 (up to 
24) 
≥ 90 
Part 2 
E 
ESRD requiring 
HD 
8 
requiring HD 
* Estimated glomerular filtration rate (eGFR) based on 
Modification of Diet in Renal Disease (MDRD) equation at 
screening. Baseline eGFR will be obtained by taking the 
mean of the eGFR obtained from screening and from 
historical values within a 3-month period from screening. If 
no historical measurement is available, a second baseline 
eGFR sample will be taken during the screening period 
(≥ 72 hours apart) and the mean of the two values will be 
used for group assignment; the second baseline eGFR sample 
may be obtained at the time of check-in.  
** Reasonable efforts will be made to enroll at least 2 
subjects with eGFR values of 30 - 40 mL/min/1.73m2

Part 1: 
Subjects in Panels A, B, C, and D will receive a single IV dose 
of MK-3866. Plasma samples will be taken at pre-specified time 
points up to 72 hours postdose, depending on the panel and urine 
samples will be collected at pre-specified time points up to 
24 hours postdose, where possible, for pharmacokinetic 
assessment of MK-3866. 
Part 2: 
Subjects in Panel E will receive a single IV dose of MK-3866 on 
two separate occasions.  
In Period 1, subjects will receive a single IV dose of MK-3866 
immediately following their normally-scheduled HD, followed 
by 72 hours plasma sampling and by 24 hours urine collection, 
where possible, for pharmacokinetic assessment of MK-3866. 
In Period 2, subjects will receive a single IV dose of MK-3866 
approximately 30 minutes prior to their normally scheduled HD 
followed by 72 hours plasma sampling and by 24 hours urine 
collection, where possible, for pharmacokinetic assessment of 
MK-3866. During this dialysis session, additional plasma and 
dialysate samples will be taken for MK-3866 analysis.  
There will be a washout period of at least 7 days between 
MK-3866 dosing in Periods 1 and 2 of Part 2. 
Both Parts: 
All subjects who received at least one dose of MK-3866 will 
return to the Clinical Research Unit (CRU) approximately 
14 days after the last dose for follow-up procedures, and to 
determine if any adverse events have occurred since the last 
study visit. 
Blinding: 
This is an open-label study. 
Number of Subjects: 
Subjects with RI: 
Up to thirty-two (32), adult, male and female (non-childbearing 
potential only) subjects will be enrolled. 
Panel A:  Eight (8) subjects with mild RI. 
Panel B:  Eight (8) subjects with moderate RI. 
Panel C:  Eight (8) subjects with severe RI. 
Panel E:  Eight (8) subjects with ESRD requiring HD.

Subjects with mild (Panel A), moderate (Panel B), and severe 
(Panel C) RI and those with ESRD (Panel E) shall be enrolled in 
parallel, and each panel shall enroll a minimum of 2 subjects of 
each gender. 
Healthy Matched Control Subjects: 
Panel D: At least 8 (up to 24) healthy subjects 
(eGFR ≥ 90 mL/min/1.73 m2), matched to the mean age 
(± 15 years), gender, and mean body mass index (BMI; ± 10%)

ESRD panels (Panels A, B, C, and E).  
Enrolment of 8 healthy matched control subjects (Panel D) will 
commence following the completion of enrolment of Panels A 
and B. Each healthy control subject will be matched to the mean 
age (± 15 years) and the mean BMI (± 10%) of the subjects in 
Panels A and B combined. There should be a minimum of 
2 subjects of each gender in each panel.  
The data from the already enrolled healthy subjects who satisfy 
the gender, mean age and BMI matching criteria of the RI 
subjects in each of Panels C and E will be used. However, if any 
of the healthy subjects do not meet the matching criteria 
described above, additional healthy subjects will be enrolled to 
result in a total of 8 healthy subjects who match the mean age 
(± 15 years) and the mean BMI (± 10%) of each of Panels C 
and E. The gender of the additional healthy subject(s) will be 
selected to ensure that there is a minimum of 2 subjects of each 
gender in the group of subjects within Panel D who match with 
each of the Panels C and E. 
The pharmacokinetic comparisons between each renally 
impaired panel (Panels A, B, C, and E) and healthy controls 
(Panel D) will include only the control subjects who meet the 
matching criteria for the respective RI panel. 
Dosage, Dosage Form, 
Route, and Dose

Each IV infusion will be administered over 30 minutes 
(±5 minutes).  
Hour 0 will be determined as the start of the infusion. 
Key Assessments: 
Pharmacokinetics: 
The following pharmacokinetic parameters will be calculated for 
MK-3866 in plasma, as appropriate, in all panels:  AUC0-∞, 
AUC0-last, AUC0-24, Ceoi (Cmax), Tmax, elimination terminal 
t½, CL, and Vz.  
The following pharmacokinetic parameters will be calculated for 
MK-3866 in urine, as appropriate, in all panels:  Ae0-24, Fe, and 
CLr. 
For subjects with ESRD on HD (Panel E only), the following 
pharmacokinetic parameters will also be calculated for MK-3866 
in plasma, as appropriate:  Ca, Cv, AUCD, AUC(1-4.5)Ca, and 
AUC(1-4.5)Cv, CLD,plasma and in dialysate: CD, AD, rr, 
AD,total, and CLD,dialysate.  
Safety: 
Safety will be monitored through physical examination, vital 
signs, 12-lead electrocardiograms (ECGs), adverse events and 
clinical laboratory tests. Summary statistics for the laboratory 
safety tests, 12-lead ECGs, and/or vital signs may also be 
computed and provided, as deemed clinically appropriate.

a. 
For details on Procedures, refer to Section 10 and/or corresponding appendices. 
b. 
Within 28 days prior to dosing. 
c. 
All subjects who received at least one dose of MK-3866 will return to the Clinical Research Unit (CRU) approximately 14 days after the last dose for follow-up procedures, 
and to determine if any adverse events have occurred since the last study visit.  
d. 
Check-in: Subjects will be admitted to the CRU on Day -2 or Day -1, at the time indicated by the CRU. 
e. 
Symptom-driven physical examinations may be performed at other times, at the Investigator’s or designee discretion. 
f. 
To be performed only once as the last study procedure for each panel:  at 24 hours post start of infusion for healthy controls (Panel D); 48 hours for subjects with mild and 
moderate RI (Panel A and B), and 72 hours for subjects with severe RI (Panel C), or prior to early termination from the study. 
g. 
Baseline eGFR will be obtained by taking the mean of the eGFR obtained from screening and from historical values within a 3 months period from screening. If no historical 
measurement is available, a second baseline eGFR sample will be taken during the screening period (≥72 hours apart) and the mean of the two values will be used for group 
assignment; the second baseline eGFR sample may be obtained at the time of check-in.  
h. 
Triplicate 12-lead ECGs to be performed at screening and for predose ECG measurement. Single 12-lead ECGs to be performed for all postdose ECG measurements.  
i. 
To be performed within 24 hours prior to dosing. 
j. 
Samples for serum chemistry will be obtained following a fast of at least 8 hours; however, in case of discontinuations or rechecks, subjects may not have fasted for 8 hours 
prior the serum chemistry sample is taken. For subjects who are anuric, urine samples for urinalysis will not be collected.

The plasma pharmacokinetic sampling time points will be completed at 24 hours post start of infusion for healthy controls (Panel D); 48 hours for subjects with mild and 
moderate RI (Panel A and B), and 72 hours for subjects with severe RI (Panel C).  
l. 
The 0.5 hour blood sample for MK-3866 pharmacokinetic should be collected at the end of the infusion. 
m. Urine collection intervals are: pre-dose (spot collection), 0 - 4, 4 - 8, 8 – 12, and 12 - 24 hours postdose. For subjects with RI, urine samples will be collected whenever 
possible, as subjects may not be able to produce urine at each interval. For subjects who are anuric, urine samples will not be collected.  
n. 
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.

The 0.5 hour blood sample for MK-3866 should be collected at the end of the infusion. 
m. If the next scheduled HD must be initiated prior the 72 hours postdose, a sample for MK-3866 analysis will be collected prior to HD. 
n. 
Urine collection intervals are: pre-dose (spot collection), 0 - 4, 4 - 8, 8 – 12, and 12 - 24 hours postdose. Urine samples will be collected whenever possible, as subjects 
may not be able to produce urine at each interval. For subjects who are anuric, urine samples will not be collected.  
o. 
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. 
p. 
All subjects who received at least one dose of MK-3866 will return to the Clinical Research Unit (CRU) approximately 14 days after the last dose for follow-up 
procedures, and to determine if any adverse events have occurred since the last study visit. 
q. 
During HD, blood samples for MK-3866 will be collected from both the pre-dialyzer and post-dialyzer blood lines; thus 2 plasma samples per time point during HD will be 
taken. A blood sample (a pre-dialyzer and post-dialyzer) will also be obtained immediately before the HD is stopped, if this time point does not coincide with a time point 
that is already scheduled. 
r. 
Dialysate samples for determination of MK-3866 will be obtained pre-dialysis, post-dialysis (before the HD is stopped), and for 1 minute every half hour during HD. 
s. 
HD session will be initiated immediately following the 0.5-hour postdose blood draw.

BACKGROUND AND RATIONALE 
7.1 
Background 
β-lactam antibiotics (penicillins, cephalosporins, carbapenems, and monobactams) are among 
the most frequently used antimicrobial agents in clinical practice. The unrelenting 
development of resistance in gram-negative bacteria, especially Pseudomonas and 
Enterobacteriaceae, to β-lactam antibiotics by the production of β-lactamases (BLs) poses a 
growing threat to the clinical utility of all β-lactams. There are 4 major classes of BLs; 
classes A, B, C, and D. Classes A, C, and D are serine-based enzymes, while class B are 
metallo-enzymes with a zinc active site required for hydrolysis of the β-lactam ring.  
MK-3866 is a potent small molecule class B metallo-β-lactamase inhibitor (MBLi) which is 
being developed as part of combination therapy with β-lactam antibiotics to restore their 
antibacterial activity against resistant metallo-β-lactamase (MBL)-expressing gram-negative 
bacteria. The ability to improve treatment of infections caused by resistant organisms through 
the addition of a β-lactamase inhibitor (BLi) is well-established by clinically used 
β-lactam/BLi combinations that inhibit class A (clavulanic acid, sulbactam, tazobactam) and 
classes A and C (avibactam, relebactam) enzymes. There are currently no clinically available 
inhibitors of class B MBLs and no good treatment options for MBL-expressing 
gram-negative bacterial infections. Therefore, the addition of an MBLi component to current 
and future treatment regimens would address a growing unmet medical need and represent a 
significant advance in the treatment of resistant gram-negative bacterial infections.

 of many MBLs.
 
 
 
 
 
  
MK-3866 has a low potential to cause drug-drug interactions (DDIs) as a perpetrator by 
inhibition or induction of cytochrome P450 enzymes (CYPs) and major transporters, 
 
 
MK-3866 has recently completed dosing the first-in-human (FIH) single ascending dose trial 
(PN001), and the multiple ascending dose trial (PN002) commenced dosing on 01-Jun-2017.

Sixteen healthy adult subjects have received at least one dose of MK-3866 in PN001. 
MK-3866 in single doses up to 1200 mg, and divided doses up to 2000 mg (2 x 1000 mg, 
administered 6 hours apart) was generally well-tolerated, with no reported serious adverse 
experiences (SAEs), AEs leading to discontinuation, or events of clinical interest.

Rationale  
7.2.1 Rationale for this Study and Study Design 
 
 
  
MK-3866 is likely to be used in patients with various degrees of RI, as a proportion of 
patients with serious gram-negative infections have baseline RI, and also patients can 
develop acute renal failure in the setting of gram-negative sepsis. The primary purpose of this 
study is thus to understand the effect of RI on the pharmacokinetics of MK-3866 in order to 
guide dosing recommendations in these patients. 
 
 
Renal clearance is expected to be the major elimination pathway for MK-3866. Parameter 
estimates were obtained from an interim pharmacokinetic analysis indicating that ~65% of 
MK-3866 is excreted in the urine following a single IV dose. Simulations conducted predict 
that the effect of RI on single dose pharmacokinetic will be a reduction in clearance, thereby 
increasing the terminal half-life and AUC. A change in the peak plasma concentration

(Cmax) following a single dose is not anticipated. However, these predictions do not take 
into consideration the role of hepatic elimination, which is anticipated to be a significant 
elimination pathway for MK-3866 as well. It is established that RI can affect the non-renal 
clearance of compounds like MK-3866, that are partially hepatically cleared, and so this trial 
will provide insight into the role of non-renal clearance mechanisms in the setting of RI. 
Based on the predominance of renal elimination of MK-3866 and the simulations performed, 
it is expected that RI will affect to varying degrees the pharmacokinetic of MK-3866, with 
the likely requirement for dosing adjustment(s). A full pharmacokinetic study design has thus 
been selected and will enable the estimation of the impact on pharmacokinetic across the 
spectrum of RI, in order to inform dose adjustments needed in each of mild, moderate, and 
severe RI, as well as the establishment of recommendations for dosing with respect to 
HD [1]. 
Given the limited developmental and reproductive toxicity data available for MK-3866, 
enrollment shall be restricted to adult males and females of non-childbearing potential who 
meet the study’s eligibility criteria. Healthy subjects and subjects with RI, but not patients 
with acute bacterial infection, will be enrolled to allow the assessment of pharmacokinetics, 
safety, and tolerability of MK-3866; these assessments may be confounded in the presence of 
active infection.  
7.2.2 Rationale for the Dose Selection 
MK-3866 is currently undergoing evaluation in clinical trials with healthy subjects; therefore 
the planned clinical dose has not yet been established. At the time of writing this protocol, 
the projected clinical dose is approximately 300 mg. However, a 200 mg dose has been 
selected for this study on the grounds that it is sufficiently close to the projected clinical dose 
so as to enable prediction of pharmacokinetic at the clinical dose, yet is anticipated to be 
well-tolerated by all study subjects, regardless of renal function. 
Because both renal (~65%) and hepatic (~35% predicted) pathways are involved in the 
elimination of MK-3866, the evaluation at the maximum possible dose (as limited by the 
tolerability considerations below) is preferred in order to maximize insight into the effect of 
RI on pharmacokinetic, in particular the impact of reduced renal clearance on hepatic 
elimination.  
In the FIH study (PN001) of MK-3866 in healthy subjects, 
 single doses of up to 
1200 mg and divided doses of up to 2000 mg (2 x 1000 mg, six hours apart) were generally 
well-tolerated, 
 
 
  
In consideration of the tolerability of MK-3866 in subjects with RI, the dose of study drug in 
this trial has been selected so that the exposure in all subjects is not expected to exceed the 
exposure at 800 mg in healthy subjects (AUC0-∞ of 272 µM*hr and Ceoi of 97 µM). 
Modeling projections predict that a 200 mg dose in ESRD subjects will produce an AUC0-∞

of 202 µM*hr (1.3X exposure margin) and Ceoi of 24 µM. There is additional confidence in 
the tolerability of the selected dose on the basis of the acceptable tolerability 
 
of a single 1200 mg dose in healthy subjects, which produced an AUC0-∞ of 439 µM*hr 
(2.2 x exposure margin for the 200 mg dose in subjects with ESRD) and Ceoi of 152 µM.  
7.2.3 Rationale for Planned Exploratory Biomarker Research 
7.2.3.1 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. 
7.2.3.2 Rationale for Future Biomedical Research 
The Sponsor will conduct Future Biomedical Research on DNA specimens consented for 
future biomedical research during this clinical trial. 
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 Appendix 2 - Collection and 
Management of Specimens for Future Biomedical Research.

INVESTIGATIONAL PLAN 
9.1 
Overall Study Design and Plan 
This is an open-label, 2-part, single dose study in renal impaired and healthy control subjects. 
Part 1 will include subjects with mild, moderate, and severe RI and healthy control subjects, 
and Part 2 will include subjects with ESRD undergoing HD. Parts 1 and 2 of the study may 
be conducted concurrently. 
Screening of subjects will occur within 28 days prior to dosing in Part 1 or prior to the first 
dose in Part 2. Up to thirty-two (32), adult, male and female (non-childbearing potential 
only) subjects with RI, and at least 8 (up to 24) age- and BMI-matched healthy control adult 
male and female subjects will be enrolled. 
Study parts and assignment to a renal function group will be as follows:

taking the mean of the eGFR obtained from screening and from historical values 
within a 3-month period from screening. If no historical measurement is available, a 
second baseline eGFR sample will be taken during the screening period (≥ 72 hours 
apart) and the mean of the two values will be used for group assignment; the second 
baseline eGFR sample may be obtained at the time of check-in. 
** Reasonable efforts will be made to enroll at least 2 subjects with eGFR values of 
30 - 40 mL/min/1.73m2  
Subjects with mild (Panel A), moderate (Panel B), and severe (Panel C) RI and those with 
ESRD on HD (Panel E) shall be enrolled in parallel, and each panel shall enroll a minimum of 
2 subjects of each gender. 
Panel D: At least 8 and up to 24 healthy subjects (eGFR ≥ 90 mL/min/1.73 m2), matched to 
the gender, mean age (± 15 years) and BMI (± 10%) of subjects in the mild, moderate, severe 
RI, and subjects with ESRD panels (Panels A, B, C, and E) as follows:  
Enrolment of 8 healthy matched control subjects (Panel D) will commence following the 
completion of enrolment of Panels A and B. Each healthy control subject will be matched to

the mean age (± 15 years) and the mean BMI (± 10%) of the subjects in Panels A and B 
combined. There should be a minimum of 2 subjects of each gender in each panel.  
The data from the already enrolled healthy subjects who satisfy the gender, mean age and 
BMI matching criteria of the RI subjects in each Panel (C and E) will be used. However, if 
any of the healthy subjects do not meet the matching criteria described above, additional 
healthy subjects will be enrolled to result in a total of 8 healthy subjects who match the mean 
age (± 15 years) and the mean BMI (± 10%) of each Panel C and E. The gender of the 
additional healthy subject(s) will be selected to ensure that there is a minimum of 2 subjects 
of each gender in the group of subjects within Panel D who match with Panels C and E. 
The pharmacokinetic comparisons between each renally impaired panel (Panels A, B, C, 
and E) and healthy controls will include only the control subjects who meet the matching 
criteria for the respective RI panel. 
In both Parts, MK-3866 will be administered IV over 30 minutes (± 5 minutes). 
Part 1: 
Subjects in Panels A, B, C, and D will receive a single IV dose of MK-3866. Plasma samples 
will be taken at pre-specified time points up to 72 hours postdose, depending on the panel 
and urine samples will be collected over pre-specified time intervals up to 24 hours postdose, 
where possible, for pharmacokinetic assessment of MK-3866. 
Part 2: 
Subjects in Panel E will receive a single IV dose of MK-3866 on two separate occasions.  
In Period 1, subjects will receive a single IV dose of MK-3866 immediately following 
completion of their normally-scheduled HD, followed by 72 hours plasma sampling and by 
24 hours urine collection, where possible, for pharmacokinetic assessment of MK-3866. 
In Period 2, subjects will receive a single IV dose of MK-3866 approximately 30 minutes 
prior to their normally scheduled HD followed by 72 hours plasma sampling and by 24 hours 
urine collection, where possible, for pharmacokinetic assessment of MK-3866. During this 
dialysis session, additional plasma and dialysate samples will be taken for MK-3866 analysis.  
There will be a washout period of at least 7 days between MK-3866 dosing in Periods 1 
and 2 of Part 2.

Selection of Study Population 
9.2.1 Inclusion Criteria 
9.2.1.1 Renal Impaired Subjects 
Subjects must fulfill all of the following inclusion criteria to be eligible for participation in 
the study, unless otherwise specified: 
1. Adult male or female (non-childbearing potential only) subjects, 18-75 years of age, 
inclusive, at screening. 
2. Has a BMI ≥ 18.0 and ≤ 40.0 kg/m2, at screening.  
3. Have a stable baseline health, based on medical history, physical examination, vital 
sign measurements, 12-lead ECGs, and clinical laboratory safety tests performed at 
screening. Subjects who do not qualify based on a reversible condition or mild 
intercurrent illness may be re-screened after the underlying condition is resolved.  
4. Liver function tests (serum alanine aminotransferase [ALT] and aspartate 
aminotransferase [AST]) and serum bilirubin (total and direct) must be within the upper 
limit of normal for the laboratory used by the clinical site. 
5. Females must be of non-childbearing potential and are defined as: 
• Postmenopausal:  defined as, without menses for at least 1 year and has a 
documented follicle stimulating hormone (FSH) level in the postmenopausal 
range at screening. 
• Surgically sterile:  defined as, status post hysterectomy or oophorectomy, or 
tubal ligation. 
NOTE: These procedures must be confirmed with medical records or via pelvic 
exam or ultrasound scan, as applicable. In the absence of documentation, 
oophorectomy may be confirmed by hormone levels, particularly FSH in the 
postmenopausal range, but tubal ligation subjects without records should be 
excluded. Information must be captured appropriately within the site's source 
documents. 
6. Male subjects with female partner(s) of child-bearing potential must agree to use a 
medically acceptable method of contraception during the study and for 90 days after 
dosing. If their partner is pregnant, males must agree to use a condom; if their partner is 
of child-bearing potential, their partner must additionally be using one of the following 
methods: hormonal contraception, intra-uterine device, diaphragm, or cervical cap. 
Spermicides alone are not an acceptable method of contraception

7. Male subjects must agree not to donate sperm from the first dose until 90 days after 
dosing. 
8. Have adequate venous access, as determined by the Investigator or designee, at 
screening. 
9. Understands the study procedures in the informed consent forms (ICFs), is willing and 
able to comply with the protocol, and provide written informed consent to the study. 
Future Biomedical Research participation is voluntary and is not required in order to 
participate in the study. 
10. For Panel A only: Baseline eGFR is ≥60 and <90 mL/min/1.73m2 based on the MDRD 
equation at screening defined as follows (for females multiply result by 0.742, if 
African American multiply result by 1.212).  
The MDRD equation is: 
eGFR = 175 x (Scr,std)-1.154 x (Age)-0.203 
Scr, std:  serum creatinine (mg/dL) measured with a standardized assay. 
Baseline eGFR will be obtained by taking the mean of the eGFR obtained from 
screening and from historical values within a 3-month period from screening. If no 
historical measurement is available, a second baseline eGFR sample will be taken 
during the screening period (≥ 72 hours apart) and the mean of the two values will be 
used for group assignment; the second baseline eGFR sample may be obtained at the 
time of check-in.  
11. For Panel B only: Baseline eGFR is ≥30 and <60 mL/min/1.73m2 based on the MDRD 
equation at screening. Reasonable efforts will be made to enroll at least 2 subjects with 
eGFR values of 30 - 45 mL/min/1.73m2. 
The MDRD equation to be used will be as above. Baseline eGFR will be obtained by 
taking the mean of the eGFR obtained from screening and from historical values within 
a 3-month period from screening. If no historical measurement is available, a second 
baseline eGFR sample will be taken during the screening period (≥ 72 hours apart) and 
the mean of the two values will be used for group assignment; the second baseline 
eGFR sample may be obtained at the time of check-in. 
12. For Panel C only: Baseline eGFR is <30 mL/min/1.73m2 based on the MDRD 
equation, but not on HD at screening.  
The MDRD equation to be used will be as above. Baseline eGFR will be obtained by 
taking the mean of the eGFR obtained from screening and from historical values within 
a 3-month period from screening. If no historical measurement is available, a second 
baseline eGFR sample will be taken during the screening period (≥ 72 hours apart) and

9.2.3 Subject Withdrawal/Discontinuation Criteria 
Subjects may withdraw consent at any time for any reason or be discontinued from the trial at 
the discretion of the Investigator should any untoward effect occur. In addition, a subject may 
be withdrawn by the Investigator or the Sponsor if enrollment into the trial is inappropriate, 
the trial plan is violated, or for administrative and/or other safety reasons. Specific details 
regarding discontinuation or withdrawal procedures, including specific details regarding 
withdrawal from Future Biomedical Research, are provided in Section 9.2.3.1. 
Discontinuation is “permanent”. Once a subject is discontinued, he/she shall not be allowed 
to enroll again. 
Subjects who are discontinued may be replaced at the discretion of the Sponsor. 
A subject must be discontinued from the study for any of the following reasons: 
• The subject withdraws consent. 
• The subject has a confirmed positive serum pregnancy test. 
• The subject has a medical condition or personal circumstance which, in the opinion of 
the Investigator and/or Sponsor, places the subject at unnecessary risk through 
continued participation in the trial or does not allow the subject to adhere to the 
requirements of the protocol.

CA22640_(MK-3866-005-00)_Final_Protocol_03Aug2017 
A subject may be discontinued from the study for any of the following reasons: 
• Adverse events. 
• Difficulties in blood collection. 
• Protocol violation (other than those listed above). 
9.2.3.1 Withdrawal/Discontinuation 
The Investigator or designee must notify the Sponsor when a subject has been 
discontinued/withdrawn from the study. If a subject discontinues for any reason at any time 
during the course of the study, the procedures scheduled at early termination (as outlined in 
Section 6) will be performed. Furthermore, the subject will be asked to return to the clinic, 
for a follow-up (approximately 14 days after dosing in Part 1 or last dose in Part 2), to 
determine if any adverse events have occurred since the last visit. Any adverse events which 
are present at the time of discontinuation/withdrawal should be followed in accordance with 
the safety requirements outlined in Section 10.1.7. 
9.2.3.1.1 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.  
9.3 
Study Restrictions 
9.3.1 Prohibitions and Concomitant Medication 
Consumption of foods and beverages containing the following substances will be prohibited 
as indicated: 
• Xanthines/Caffeine: 24 hours prior to dosing until the last pharmacokinetic sample 
collection in Part 1 and 24 hours prior to each dosing in Part 2 until the last 
pharmacokinetic sample collection following each dosing;

• Alcohol: 48 hours prior to dosing until the last pharmacokinetic sample collection in 
Part 1 and 24 hours prior to each dosing in Part 2 until the last pharmacokinetic 
sample collection following each dosing; 
• Grapefruit/Seville orange: 14 days prior to dosing in Part 1 and first dose in Part 2 
and throughout the study. 
Concurrent medication during the course of the protocol including both prescription and non-
prescription drugs must first be discussed with the Investigator and Sponsor Clinical Monitor 
prior to dosing in Part 1 or first dose in Part 2, unless appropriate medical care necessitates 
that therapy should begin before the Investigator and Sponsor Clinical Monitor can be 
consulted. Once dosed with study drug, acetaminophen (up to 2 g per 24 hours) may be 
administered at the discretion of the Investigator. 
Appropriate sources will be consulted by the Investigator or designee to confirm lack of 
pharmacokinetic/pharmacodynamic interaction with the study drug. If deviations occur, the 
Investigator will decide on a case-by-case basis whether the subject may continue 
participation in the study based on the time the study drug and concomitant medication was 
administered and its pharmacology.  
All medications taken by subjects during the course of the study will be recorded. 
For Renal Impaired Subjects: 
All prescription or non-prescription medications (including St. John’s Wort) that are strong 
inhibitors or strong inducers of CYP3A enzyme, or inhibitors of OATP1B1/1B3 transporters 
will be prohibited. These enzyme/transporter inhibitors and inducers will not be allowed for 
at least 14 days and 28 days respectively prior to first dosing and throughout the study. 
Moderate and weak CYP3A inhibitors or inducers may be deemed acceptable following 
consultation with the Sponsor Clinical Monitor and the Investigator. 
Subjects who are taking certain prescription medications to treat manifestations of renal 
disease or medications needed to treat stable diseases (e.g., angiotensin converting enzyme 
inhibitors, angiotensin II receptor antagonists, beta-blockers, diuretics) may be allowed to 
participate in the study at the discretion of the Investigator and following consultation with 
the Sponsor Clinical Monitor. Subjects must be on a stable regimen for at least 2 weeks (or 
5 half-lives of the concomitant medication, whichever is longer) prior to dosing in Part 1 or 
first dose in Part 2 and is able to withhold the use 4 hours prior to and 4 hours postdose of 
study drug. If a subject is prescribed prohibited medication, upon discussion between the 
Sponsor and the Investigator, the Investigator may substitute the previously prescribed 
medication to an allowed one for the purpose of this study. 
Any medication (including over-the-counter) that would significantly alter eGFR, which, by 
the determination of the Investigator, might interfere with the study (e.g., cimetidine) must be 
discontinued at least 2 weeks (or 5 half-lives of the compound, whichever is longer) prior to 
dosing in Part 1 or first dose in Part 2 and throughout the study.

For Healthy Subjects: 
Any medication or substance (including prescription or over-the-counter, vitamin 
supplements, natural or herbal supplements) which cannot be discontinued at least 14 days 
prior to dosing and throughout the study are prohibited. All prescription or non-prescription 
medications (including St. John’s wort) that are strong inhibitors or strong inducers of 
CYP 3A enzyme, or inhibitors of OATP1B1/1B3 transporters will be prohibited for at least 
14 days (for inhibitors) and 28 days (for inducers) prior to dosing and throughout the study. 
Moderate and weak CYP 3A inhibitors or inducers may be deemed acceptable following 
consultation with the Sponsor Clinical Monitor and the Investigator. Subjects who are taking 
medications for stable diseases for ~1 month for prior to dosing may be allowed to 
participate in the study at the discretion of the Investigator.  
9.3.2 Meals 
Water (except water provided with dosing) will be restricted 1 hour prior to and 1 hour after 
study drug administration, but will be allowed ad libitum at all other times. Other fluids may 
be given as part of the standard meals and/or snacks, but will be restricted at all other times 
throughout the confinement period. 
Subjects will fast for at least 1 hour prior to dosing in Part 1 or each dose in Part 2. Subjects 
will continue the fast for at least 1 hour postdose.  
On all days that subjects are confined in the CRU, standard meals and snacks will be 
provided at appropriate times. When confined in the CRU, subjects will fast from all food 
and drink except water between meals and snacks. 
Each meal and/or snacks served at the CRU will be standardized, and will be similar in 
caloric content and composition. 
9.3.3 Activity 
Subjects will remain ambulatory or seated upright for the first 4 hours following study drug 
administration, except when they are supine or semi-reclined for study procedures.  
However, should adverse events occur at any time, subjects may be placed in an appropriate 
position or will be permitted to lie down on their right side. 
Subjects will be instructed to refrain from strenuous physical activity which could cause 
muscle aches or injury, including contact sports at any time from screening until completion 
of the study.

9.4 
Treatments 
9.4.1 Treatments Administered 
Please refer to the Study Operations Manual provided by the Sponsor for details of 
preparation and dispensing procedures. 
Part 1: 
Subjects will receive a single IV infusion of 200 mg MK-3866 at Hour 0 on Day 1. 
Part 2: 
Subjects will receive a single IV infusion of 200 mg MK-3866 at Hour 0 on Day 1, 
immediately after completion of the scheduled HD (Period 1), and at Hour 0 on Day 1, 
approximately 30 minutes prior to initiation of the scheduled HD (Period 2). 
Both Parts: 
Each IV infusion will be administered over 30 minutes (±5 minutes).  
Hour 0 will correspond to the start of the IV infusion. 
The time at which the IV infusion starts and ends will be recorded. 
The pharmacy at the CRU will provide the IV dose ready for infusion for each subject and 
for each study period. 
Each IV infusion will be administered using an IV infusion pump system over 30 minutes 
(± 5 minutes), while subjects are seated or in a semi-reclined position, except when a supine 
position is dictated by study procedures. Should the need arise to change the infusion rate 
(i.e., due to an adverse event), changes to the infusion rate and the times at which those 
changes are made will be documented. 
9.4.2 Method of Assigning Subjects to Treatment Groups 
Each subject will be assigned a unique identification number upon screening. Subjects who 
complete the study screening assessments and meet all the eligibility criteria will receive 
MK-3866 according to allocation schedule generated by Celerion. 
If replacement subjects are used, the replacement subject number will be 100 more than the 
original (e.g., allocation number 0101 will replace allocation number 0001). 
9.4.3 Blinding 
This is an open-label study.

9.4.4 Treatment Compliance  
MK-3866 IV infusion will be performed by a qualified designee. The qualified designee will 
visually inspect the infusion pump device prior and after IV infusion, to ensure that the 
subject has received the entire dose. Should an infusion dosing be interrupted or incomplete 
for any reason (e.g., distal occlusion, proximal air, infiltration, large droplet of study 
medication on the surface of the skin), the initial start and stop times of the infusion, as well 
as all reinitiating start and stop times of the infusion will be recorded. Additionally, the 
pre-and post-infusion bag weights will be recorded.

10 STUDY PROCEDURES 
The Study Events Flow Chart (Section 6) summarizes the clinical procedures to be 
performed at each visit. Individual clinical procedures are described in detail below. 
Additional evaluations/testing may be deemed necessary by the Investigator and/or the 
Sponsor for reasons related to subject safety. 
For this study, the blood collection for MK-3866 is the critical parameter and needs 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, but can be performed prior 
or after the prescribed/scheduled time. 
Any nonscheduled procedures required for urgent evaluation of safety concerns take 
precedence over all routine scheduled procedures. 
10.1 Safety Assessment 
10.1.1 Screening 
Within 28 days prior to dosing, medical history and demographic data, including name, sex, 
age, race, ethnicity, body weight (kg), height (cm), BMI (kg/m2) and history of tobacco use 
will be recorded. Each subject will have a physical examination, vital sign measurements 
(heart rate, blood pressure, temperature, and respiratory rate), 12-lead ECG, and the 
laboratory tests of hematological, hepatic and renal function and additional tests as noted in 
Section 10.1.6. 
10.1.2 Physical Examination 
A full physical examination will be performed as outlined in the Study Events Flow Chart 
(Section 6). Symptom-driven physical examinations may be performed at other times, if 
deemed necessary by the Investigator or designee.  
10.1.3 Vital Signs 
Single measurements of body temperature, respiratory rate, blood pressure, and heart rate, 
will be measured as outlined in the Study Events Flow Chart (Section 6). 
Vital signs may be taken at any other times, if deemed necessary. Blood pressure and heart 
rate measurements will be performed with subjects in a seated position for at least 1 minute, 
except when they are supine or semi-reclined because of study procedures and/or adverse 
events (e.g., nausea, dizziness) or if deemed necessary by the Investigator or designee. 
Blood pressure and heart rate will be measured within 24 hours prior to Day 1 dosing for the 
predose time point. When scheduled postdose, vital signs will be performed within 
approximately 15 minutes of the scheduled time point.

CA22640_(MK-3866-005-00)_Final_Protocol_03Aug2017 
10.1.4 ECG Monitoring 
Triplicate 12-lead ECGs will be performed at screening and predose; single 12-lead ECGs 
will be performed as outlined in the Study Events Flow Chart (Section 6), at all other times. 
Predose triplicate 12-lead ECGs will be measured within 24 hours prior to dosing. The 
average value from the triplicate 12-lead ECGs collected prior to dosing will be considered 
the baseline ECG. 
Timing and recording technique for triplicate 12-lead ECGs will be standardized for all 
subjects. Subjects will be required to lie quietly in a supine position with minimal movement 
and minimal exposure to noise and other environmental stimuli prior to and during ECG 
extraction. ECGs will be interpreted, signed, and dated by the Investigator or his/her 
designee. The ECGs will be classified as normal, abnormal but not clinically significant, or 
having a clinically significant abnormality. In addition, ECG parameter values of ventricular 
rate, PR interval, QRS duration, and QT interval (corrected and uncorrected) from the 
automated reading will be noted on the case report form (CRF). All clinically significant 
findings will be recorded as AEs for subjects enrolled in the study. An average for QTcF 
interval will be calculated for each triplicate. 
Single 12-lead ECGs will be performed within approximately 20 minutes of the scheduled 
time point. Single ECGs will be performed with subjects in a supine position for at least 
5 minutes. All ECG tracings will be reviewed by the Study Physician or his/her designee. 
A subject will be withdrawn from the study by the Study Physician if, in their medical 
judgment, ECG findings are present which make continued study participation not in the 
subject’s best interest. 
10.1.5 Hemodialysis (ESRD Subjects Only) 
ESRD subjects on HD will receive HD as per their regular schedule and blood and dialysate 
sampling be collected as outlined in the Study Events Flow Chart (Section 6).  
Dosing in Period 1 will occur immediately following completion of a normally scheduled 
HD session. For subjects following a Monday, Wednesday, Friday HD schedule, MK-3866 
will be administered immediately following their Friday HD session. For subjects following 
a Tuesday, Thursday, Saturday HD schedule, MK-3866 will be administered immediately 
following their Saturday HD session. The 72-hour HD (either Monday or Tuesday) should 
initiate immediately following the 72-hour blood draw. If HD must be initiated prior to 
72 hours postdose, a sample for MK-3866 analysis will be collected prior to HD, and the 
time recorded. 
Dosing in Period 2 will occur approximately 30 minutes prior to the normally scheduled HD 
session. For subjects following a Monday, Wednesday, Friday HD schedule, MK-3866 will 
be administered prior to their Friday HD session. For subjects following a Tuesday, 
Thursday, Saturday HD schedule, MK-3866 will be administered prior to their Saturday HD

session. The subsequent HD session should initiate immediately following the 30 minute 
blood draw. 
In Period 2, the HD period will be approximately 4 hours for all subjects. Blood samples 
collected during HD will be collected from both the pre-dialyzer and post-dialyzer blood 
lines.  
The blood flow, dialysate flow, and the make and model of the dialyzer will be recorded.

§ 
Any unexplained drug-related hematuria or evidence of triphosphate 
crystals should be referred to a nephrologist. 
10.1.7 Assessing and Recording Adverse Events  
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 
unfavorable 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  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. 
For allocated subjects only, all adverse events that occur after the consent form is signed but 
before allocation must be reported by Investigator if they are the result of a 
protocol-specified intervention, including but not limited to washout or discontinuation of 
usual therapy, diet treatment, or a procedure. From the time of allocation through 14 days 
following cessation of treatment, all adverse events must be reported by the Investigator. 
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 10.1.7.3.1. The Investigator will make every attempt to follow all 
subjects with non-serious adverse events for outcome. Any unexplained drug-related 
hematuria or evidence of triphosphate crystals should be referred to a nephrologist.

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). 
10.1.7.1 Definition of an Overdose for This Protocol and Reporting of Overdose to the 
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 or 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). 
10.1.7.2 Reporting of Pregnancy and Lactation to the Sponsor 
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 allocation 
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, treatment or a procedure. Pregnancies and lactations 
that occur from the time of allocation through 14 days following cessation of Sponsor’s 
product must be reported by the Investigator. 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).

10.1.7.3 Immediate Reporting of Adverse Events 
10.1.7.3.1 Serious Adverse Events  
A serious adverse event is any adverse event occurring at any dose or during any use of 
Sponsor's product that has the following outcome: 
• Death 
• Immediately life threatening 
• Persistent or significant disability/incapacity 
• Inpatient hospitalization or prolongation of hospitalization 
• Congenital anomaly/birth defect 
• 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 serious adverse events to meet certain local requirements. Therefore, these events are 
considered serious by the Sponsor for collection purposes. 
• Cancer 
• Overdose 
Refer to Table 1 for additional details regarding each of the above criteria. 
For the time period beginning when the consent form is signed until treatment allocation, 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, treatment or a 
procedure. 
For the time period beginning at treatment allocation through 14 days following cessation of 
treatment, 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). 
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.

10.1.7.3.2 Events of Clinical Interest 
Selected non-serious and serious adverse events are also known as ECI and must be reported 
to the Sponsor. 
For the time period beginning when the consent form is signed until treatment allocation, 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, treatment or a procedure. 
For the time period beginning at treatment allocation through 14 days following cessation of 
treatment, 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). 
Events of clinical interest for this trial include: 
• an overdose of Sponsor's product, as defined in Section 10.1.7.1 that is not associated 
with clinical symptoms or abnormal laboratory results.  
• an elevated AST or ALT laboratory value that is greater than or equal to three times 
(3X) the upper limit of normal (ULN) and an elevated total bilirubin laboratory value 
that is greater than or equal to 2X the ULN and, at the same time, an alkaline 
phosphatase laboratory value that is less than 2X the ULN, 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 may 
require 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. 
10.1.7.4 Evaluating Adverse Events 
An Investigator who is a qualified physician will evaluate all adverse events with respect to 
the elements outlined in Table 1. The Investigator’s assessment of causality is required for 
each adverse event. Refer to Table 1 or instructions in evaluating adverse events.

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 is any adverse event occurring at any dose or during any use of Sponsor's 
product that: 
†Death; or 
†Immediately 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 
†Persistent or significant disability/incapacity (substantial disruption of one’s ability to conduct 
normal life functions); or 
†Inpatient hospitalization or prolongation of 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 [including hospitalization for an elective procedure] 
for a preexisting condition which has not worsened does not constitute a serious adverse event.); or 
†Congenital anomaly/birth defect (in offspring of subject taking the product regardless of time to 
diagnosis); or 
Cancer; or 
Overdose (whether accidental or intentional). Any adverse event associated with an overdose is 
considered a serious adverse event. An overdose that is not associated with an adverse event is 
considered a non-serious ECI and must be reported within 24 hours. 
Other important medical event 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 †). 
None 
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  
The action taken is in reference to the either the Sponsor’s Product or the Interacting Drug. Did the 
adverse event cause the Sponsor's product or the Interacting Drug to be: 
None

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 adverse event form, ensures that a medically qualified assessment of causality 
was done. This initialled 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 adverse event; 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 adverse event follow in a reasonable temporal sequence from administration 
of the Sponsor's product?  
Is the time of onset of the adverse event compatible with a drug-induced effect 
(applies to trials with investigational medicinal product)? 
Likely Cause 
Is the adverse event not reasonably explained by another etiology such as underlying 
disease, other drug(s)/vaccine(s), or other host or environmental factors 
Dechallenge 
Was the Sponsor's product discontinued or dose/exposure/frequency reduced? 
If yes, did the adverse event 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 adverse event resulted in death or 
permanent disability; (2) the adverse event 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 adverse event 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 adverse event 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 U.S. CLINICAL MONITOR AND THE INSTITUTIONAL REVIEW 
BOARD/INDEPENDENT ETHICS COMMITTEE. 
Consistency 
with Trial 
Treatment 
Profile 
Is the clinical/pathological presentation of the adverse event 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).

Related (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 adverse event onset relative to the administration of the Sponsor's product is 
reasonable. The adverse event is more likely explained by the Sponsor's product than 
by another cause. 
Not Related (there is not a 
reasonable possibility of 
Sponsor's product relationship) 
Subject did not receive the Sponsor's product OR temporal sequence of the adverse 
event onset relative to administration of the Sponsor's product is not reasonable OR 
there is another obvious cause of the adverse event. (Also entered for a subject with 
overdose without an associated adverse event.) 
10.1.7.5 Sponsor Responsibility for Reporting Adverse Events  
All adverse events will be reported to regulatory authorities, IRB or independent ethics 
committees (IECs), and Investigators in accordance with all applicable global laws and 
regulations i.e., per ICH Topic E6 (R1) Guidelines for Good Clinical Practice. 
10.2 Pharmacokinetic Assessment 
10.2.1 Blood Sampling and Processing 
For all subjects, blood samples for the determination of MK-3866 will be collected at 
scheduled time points as delineated in the Study Events Flow Chart (Section 6). 
Instructions for blood sampling, collection, processing, and sample shipment for MK-3866 
will be provided separately. 
Blood collections outside the following windows will be considered deviations: 
Hour 
Deviation window 
0 to 1 hour 
± 5 minutes 
> 1 to < 24 hour 
± 15 minutes 
≥24 hour 
± 30 minutes 
10.2.2 Urine Collection 
Prior to the predose sample, each subject will be instructed as to urine collection methods.  
Urine samples for determination of MK-3866 concentrations will be collected over selected 
intervals as outlined in the Study Events Flow Chart (Section 6). For subjects with mild, 
moderate, and severe RI, and subjects with ESRD, urine samples will be collected whenever 
possible, as subjects may not be able to produce urine within each interval. For subjects who 
are anuric, urine samples for urinalysis will not be collected. 
On Day 1, a spot collection will be obtained prior to dosing for the pre-dose sample. Subjects 
will be asked again to empty their bladder within approximately 15 minutes prior to dosing, 
and no urine will be collected at this time unless it is needed for the pre-dose sample. Only 
one predose urine sample will be collected on Day 1.

After administration of MK-3866, during the 24 hour period, all urine will be collected 
completely. Urine portions will be pooled per subject within any planned collection interval. 
Just prior to the end of each sampling interval, subjects will be encouraged to void their 
bladder again to complete the collection. If they void at any time during the collection 
interval, the time should be documented. Should this be the case, subjects need to attempt to 
void again at the end of the collection period, as scheduled. However, should subjects be 
unable to void, this will be documented as well. 
Urine will be refrigerated during the collection intervals. The weight of an empty urine 
collection container and total weight of urine collected during each timed interval will be 
recorded. 
Instructions for urine collection, processing, and sample shipment for MK-3866 will be 
provided separately. 
10.2.3 Dialysate Collection (Part 2 only) 
For ESRD subjects only, dialysate samples will be collected at scheduled time points as 
delineated in the Study Events Flow Chart (Section 6).  
Instructions for dialysate sampling, collection, processing, and sample shipment for 
MK-3866 will be provided separately. 
10.3 Planned Genetic Analysis Sample Collection 
Sample collection, storage and shipment instructions for Planned Genetic Analysis samples 
will be provided separately.

11.2 Statistical Methods 
The statistical analysis of the data obtained from this study will be the responsibility of the 
Data Management and Biometrics department at Celerion. 
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 (CSR). 
Additional statistical analyses, other than those described in this section, may be performed if 
deemed appropriate. 
11.2.1 Determination of Sample Size 
The sample size selected for each population to evaluate the effect of RI on the 
pharmacokinetic of MK-3866 was not chosen to satisfy any a priori statistical requirement. 
This sample size (N=8 per group) has historically been shown to be sufficient for studies of 
this type and should provide adequate data to support the planned analyses. Nevertheless, 
estimates of the expected precision of the estimates, based on these sample sizes are 
presented below. 
The precision of the estimates of ratios of geometric means obtained from this study can be 
assessed by calculating the half-width of the 90% confidence intervals expected for the given 
sample size and assumed variability.  The estimated between-subject variance for log 
AUC0-∞ is 0.0196 log ng*hr/mL from the FIH study (PN001). Since the between subject 
variability in subjects with severe RI has historically been seen to be 2-3 fold higher in many 
studies, the between subject variability obtained from healthy subjects was inflated by a 
factor of 2 for subjects with severe RI and was used for the following calculations. With 8 
renally impaired subjects and 8 healthy matched subjects, the half-width of the 90%

CA22640_(MK-3866-005-00)_Final_Protocol_03Aug2017 
confidence interval for the arithmetic mean AUC0-∞ on the log scale will be 
0.151 log ng*hr/mL. The lower and upper 90% confidence limits for the true ratio of 
geometric means will be given by OBS/1.163 and OBS x 1.163, where OBS is the observed 
ratio of geometric means. Thus, for example, if the observed ratio of geometric means was 
1.5, the 90% confidence interval would be (1.29, 1.74).  
11.2.2 Subjects to Analyze 
The decision as to which plasma samples collected will be assayed for evaluation of 
pharmacokinetics/pharmacodynamics will be collaboratively determined by the Departments 
of Quantitative Pharmacology and Pharmacometrics and Translational Pharmacology. If 
indicated, these samples may also be assayed and/or pooled for assay in an exploratory 
manner for metabolites and/or additional pharmacodynamic markers. 
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 they actually received.  
All Subjects as Treated:  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:  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 
violations. 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 will be included in the 
primary analysis dataset. This population will be used for the pharmacokinetic analyses. 
11.2.3 Analysis Overview 
11.2.3.1 Interim analysis  
An interim statistical analysis of the pharmacokinetic data obtained in moderate RI subjects 
will be performed, including a comparison with data in healthy control subjects from this 
study. 
For this interim statistical analysis, values for the pharmacokinetic parameters AUC0-∞, 
AUC0-last, AUC0-24, and Ceoi (Cmax) of MK-3866 will be estimated and compared to 
concurrent healthy control subjects. A Linear Fixed Effects (LFE) Model will be used for the 
analysis of natural log-transformed pharmacokinetic parameters:  AUC0-∞, AUC0-last, 
AUC0-24, and Ceoi (Cmax) separately. The LFE model will contain a categorical factor for 
population (moderate RI and healthy control subjects), and possible covariates for age, 
gender, and BMI, if statistically significant. A two-sided 90% confidence interval for the 
mean differences of AUC0-∞, AUC0-last, AUC0-24, and Ceoi (Cmax), of MK-3866 will be 
calculated based on the above model. These confidence limits will then be exponentiated to

obtain confidence intervals for the GMR (moderate RI /healthy) for AUC0-∞, AUC0-last, 
AUC0-24, and Ceoi (Cmax) of MK-3866. Individual and mean concentrations versus time 
plots profiles will be also be provided. 
11.2.3.2 Primary Analysis  
If a different group of healthy matched control subjects are needed to match the mean age 
and BMI for the RI and ESRD groups, then separate analyses will be performed for the 
populations as follows: 
• Mild RI and moderate RI versus an appropriate group of healthy matched control 
subjects; 
• Severe RI versus an appropriate group of healthy matched control subjects; 
• ESRD subjects (non HD and HD) versus an appropriate group of healthy matched 
control subjects. 
If a single set of healthy matched control subjects can be used for comparison with all RI and 
ESRD groups, the following analysis will be used. 
Separately for each pharmacokinetic parameter, individual values of AUC0-∞, AUC0-last, 
AUC0-24, Ceoi (Cmax), and CL will be natural log-transformed and evaluated with a linear 
fixed-effects model containing a categorical effect for populations. The REPEATED 
statement with the GROUP=Population option will be used in SAS PROC MIXED to 
estimate separate variances for each population. The Kenward and Roger adjustment will be 
used to calculate the denominator degrees of freedom for the fixed-effect (DDFM=KR). 
Ninety-five percent (95%) confidence intervals for the least squares means for each 
population will be constructed on the natural log scale and will reference the t-distribution. 
Exponentiating the least-squares means and their corresponding 95% confidence intervals 
will yield estimates for the population geometric means and confidence intervals about the 
geometric means on the original scale.  
To compare subjects with RI in each of the renal categories (mild RI, moderate RI, severe RI, 
ESRD nonHD and ESRD HD) to matching subjects with normal renal function, a two sided 
90% confidence interval for the true difference in means (RI/normal renal function) will be 
calculated for each PK parameters (AUC0-∞, AUC0-last, AUC0-24, Ceoi (Cmax), and CL) 
using the mean square error from the model and referencing a t-distribution. For each of the 
RI populations, these confidence limits will be exponentiated to obtain the 90% confidence 
interval for the true ratio of geometric means (RI/normal renal function) for each 
pharmacokinetic parameter. 
Figures showing individual pharmacokinetic values with GMs (95% confidence intervals) by 
population, plotted on the natural log scale, will be provided for AUC0-∞, AUC0-last, 
AUC0-24, Ceoi (Cmax), and CL.

Individual values will be listed for each pharmacokinetic parameter (AUC0-∞, AUC0-last, 
AUC0-24, Ceoi (Cmax), Tmax, elimination terminal t½, CL, Vz, and Fe) by population, and 
the 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). 
11.2.3.3 Secondary Analysis 
Objective 1 
To evaluate the extent to which MK-3866 is removed from plasma by HD, a linear mixed 
effect model with population (ESRD non HD, ESRD HD) as a fixed effect will be used. An 
unstructured covariance matrix will be used to allow for unequal treatment variances and to 
model the correlation between the two treatment measurements within each subject via the 
REPEATED statement in SAS PROC MIXED. Kenward and Roger's method will be used to 
calculate the denominator degrees of freedom for the fixed effects (DDFM=KR). 
A natural log transformation will be applied to CL, AUC0-∞, AUC0-last, and Ceoi (Cmax). 
For each pharmacokinetic parameter, 95% confidence intervals for the least squares mean 
will be constructed on the natural log scale and will reference the t-distribution. 
Exponentiating the least-squares means and their corresponding 95% confidence intervals 
will yield estimates for the population geometric means and confidence intervals about the 
geometric means on the original scale.  
A two sided 90% confidence interval for the true difference in means (ESRD HD - ESRD 
non HD) will be calculated for each pharmacokinetic parameter (AUC0-∞, AUC0-last, Ceoi 
[Cmax], and CL) using the mean square error from the model and referencing a t-
distribution. These confidence limits will be exponentiated to obtain the 90% confidence 
interval for the true ratio (GMR) of geometric means (ESRD HD / ESRD non HD) for each 
pharmacokinetic parameter. 
Plots with individual ratios overlaid with GMR and corresponding 90% confidence interval 
will be provided for CL, AUC0-∞, AUClast, and Ceoi (Cmax). 
Individual listings and descriptive statistics for CLD,plasma, CLD,dialysate, AD, 
AD(%dose), AUCD, AUC(1-4.5)Ca, AUC(1-4.5)Cv following a single-dose administration 
of MK-3866 will be provided for subjects with ESRD receiving HD. 
Individual listings and descriptive summary statistics may be provided for CLr for those 
ESRD subjects in whom it is possible to determine CLr. 
Objective 2 
Separately for each urine pharmacokinetic parameter, where possible, individual values of 
Ae0-24, Fe and CLr will be natural log-transformed and evaluated with a linear fixed-effects

intervals for the least squares means for each population will be constructed. To compare 
subjects with RI in each of the renal categories (mild RI, moderate RI, severe RI, ESRD 
nonHD and ESRD HD) to matching subjects with normal renal function, a two sided 90% 
confidence interval for the true difference in means (RI/normal renal function) will be 
calculated for each urine pharmacokinetic parameter (Ae0-24, Fe and CLr).  
Individual values will be listed for each urine pharmacokinetic parameter (Ae0-24, Fe and 
CLr) by population, and non-model-based descriptive statistics will be provided. 
11.2.3.4 Exploratory Analysis  
For this analysis, all the data from Part 1 will be included. 
In addition to running the primary regression analysis below using BSA normalized eGFR as 
the measure of renal function for each subject, the analysis will also be run using BSA 
un-normalized eGFR and CLcr from the C-G equation.  
Separately for each pharmacokinetic parameter, individual values of AUC0-∞, AUC0-last, 
AUC0-24, Ceoi (Cmax), CL, and CLr will be evaluated with a linear mixed effects model 
containing eGFR as a continuous variable. The subject’s mean renal function value derived 
from 2 serum creatinine measurements at Screening will be used for the analysis.  Estimates 
of the slope and intercept, together with corresponding 95% confidence intervals will be 
obtained. The estimated mean and corresponding 95% confidence interval for each RI group 
will be predicted at the midpoint of the defined eGFR range for each group (75, 45, and 15 
for mild, moderate and severe, respectively). However, for the normal renal function 
subjects, the estimated mean and corresponding 95% confidence interval will be predicted at 
the median of the observed eGFR values.  
The data will be examined for departures from the assumptions of the model. The residuals 
from the model will be examined for normality using diagnostic plots such as residuals vs 
predicted values and normal probability plots of residuals. Lack of fit will also be visually 
assessed. 
If the model used does not fit the data adequately, other models, such as natural log 
transformed pharmacokinetic versus renal function or natural log transformed 
pharmacokinetic versus natural log transformed renal function, will be explored. Other 
transformations or non-linear models will also be considered.  
Additionally, plots of MK-3866 pharmacokinetic parameter values AUC0-∞, AUC0-last, 
AUC0-24, Ceoi (Cmax), CL, and CLr versus eGFR along with a regression line and 95% 
confidence bands for regression line will be constructed. Different symbols will be used to 
identify different renal function groups. Additionally, separate plots of AUC0-∞ and Ceoi 
(Cmax) values vs age and body weight will be provided. 
Summary Statistics using BSA un-normalized eGFR:  The subjects will be re-categorized 
into different renal categories based on their BSA un-normalized eGFR and non-model based

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 Appendix 1. 
The Investigator also agrees to allow monitoring, audits, IRB/ERC 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 GCP 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. 
Trial documentation will be promptly and fully disclosed to the Sponsor by the Investigator 
upon request and also shall be made available at the trial site upon request for inspection, 
copying, review and audit at reasonable times by representatives of the Sponsor or any 
regulatory authorities. The Investigator agrees to promptly take any reasonable steps that are 
requested by the Sponsor as a result of an audit to cure deficiencies in the trial documentation 
and worksheets/case report forms. 
The Investigator must maintain copies of all documentation and records relating to the 
conduct of the trial in compliance with all applicable legal and regulatory requirements. This 
documentation includes, but is not limited to, the protocol, worksheets/case report forms, 
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 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 discarding 
trial and/or subject files.

ICH GCP 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 Investigators 
at the different trial sites in that Member State, according to national regulations. For a 
single-center trial, the Protocol CI is the 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 [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 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. 
12.10 Publication Policy 
The Sponsor will provide separate guidance on the criteria for publication of clinical trial 
data when contacted for permission to publish. 
12.11 Privacy Notice 
In order to comply with government regulations governing clinical studies, as well as 
ICH GCP 3.2.1, Merck & Co., Inc., and its corporate affiliates ("Sponsor"), is required to 
record the name and address of each IRB or IEC member that reviews and approves this 
study. The Sponsor is also required to document that each IRB or IEC meets regulatory and 
ICH GCP requirements by requesting and maintaining records of the names and 
qualifications of the IRB/IEC members and to make these records available for regulatory 
agency review upon request by those agencies (ICH GCP 8.2.8).

Appendix 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 prior 
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.

CA22640_(MK-3866-005-00)_Final_Protocol_03Aug2017 
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).

trial protocol, and in signing the protocol, agree to support these ethical and scientific 
standards.

Appendix 2: Collection and Management of Specimens for Future Biomedical 
Research 
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 10.4- Future 
Biomedical Research Samples will be used in various experiments to understand: 
• The biology of how drugs/vaccines work 
• Biomarkers responsible for how a drug/vaccine enters and is removed by the body 
• Other pathways drugs/vaccines may interact with 
• 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.

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. CRF Documentation for Future Biomedical Research Specimens 
Documentation of subject consent for Future Biomedical Research will be captured in 
the Case Report Forms (CRFs). 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 
name in any published reports about this study or in any other scientific publication or 
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.
