Study 
Population
Subjects enrolled in this study will be males and females, 2 to < 18 years of age, with a diagnosis of 
atopic dermatitis, based upon the American Academy of Dermatology atopic dermatitis diagnostic 
recommendations (2014). Subjects that are 2 to less than 12 years of age will have atopic dermatitis that 
A (excluding scalp and venous access areas). Subjects that are at least 12 years but 
less than 18 years of age will have 
25% BSA involvement (excluding scalp and venous access areas).  
Study Design
This multicenter, open-label study, will evaluate the pharmacokinetics, safety, tolerability, and the 
exploratory efficacy of MM36 1% ointment when applied twice daily for up to 4 weeks in subjects 2 to < 
18 years of age with atopic dermatitis, at the upper range of disease severity. This study will also 
evaluate the systemic availability of MM36 1% when applied topically under maximal use conditions.  
Following screening (within 30 days prior to the first application of study drug) and confirmation of 
study qualification, subjects will be registered and assigned (V2) to one of three treatment groups based 
on the subject’s age at Screening (V1). The first dose of study drug will be applied in the study clinic 
(V2/Day 1) and blood samples will be collected for pharmacokinetic (PK) evaluation (plasma 
concentration of MM36) prior to the first application (0 hours) and at 1 hour (± 15 minutes), 4 hours (± 
30 minutes) and at 8 hours (± 1 hour) post application. On Day 15, the study drug will again be applied 
in the study clinic, and blood samples will be collected for PK prior to dosing and at 1 hour (± 15 
minutes), 4 hours (± 30 minutes) and at 8 hours (± 1 hour) post application.
At Screening (V1) and Baseline (V2), subjects with atopic dermatitis that are 2 to less than 12 years of 
(excluding scalp and venous access 
areas), and subjects 12 year
(excluding scalp and 
venous access areas) (i.e., maximal use conditions). The same (or greater, BSA if area involved expands) 
amount of study drug topically applied at baseline will continue to be applied twice daily, to the same

area where study drug was applied on Day 1, even if the % BSA improves over the course of the first 2 
weeks (14 days) of treatment. Between Day 15 (after the maximal use application and collection of PK 
samples) and Day 28, the study drug will only be applied to the involved areas. The last application of 
study drug will be given the evening before the final visit (V6). 
An independent Data Safety Monitoring Board (DSMB) will facilitate the management and identification 
of potential safety concerns, on a regular basis, that could affect the safety of trial subjects, and will 
examine whether the information collected during these periodic intervals is consistent with knowledge 
about the product’s safety (e.g., unanticipated adverse events). The DSMB will also assess whether 
revisions to the study protocol and/or consent are required, and will evaluate the overall progress of the 
study. Details regarding the policies and procedures of the DSMB and intervals and data to be evaluated 
will be described in the DSMB Charter. 
Description of 
Test Article,

Statistical 
Analysis
Sample Size
The sample size is not driven by inferential statistics. A sample size of 32 subjects is set for qualitative 
investigation of the pharmacokinetic profile as well as the safety and tolerability and responsiveness 
(efficacy) of MM36 1% when applied topically twice daily for 4 weeks to pediatric subjects 2 to < 18 
years of age.
Analysis Population
Two populations will be used for analysis: safety and intent-to-treat. The definition of these populations 
follows:
Safety Population:  All enrolled subjects who received at least one dose of study medication and 
have at least one post-baseline safety assessment constitute the Safety Population.
Intent-to-Treat (ITT) Population:  All enrolled subjects who took at least one dose of study 
medication constitute the Intent-to-Treat Population.
PK and safety data will be analyzed based on the safety population. Efficacy data will be analyzed based 
on the ITT population.
Primary and Secondary Analysis
Pharmacokinetics
Individual plasma concentrations of MM36 and its metabolites (MAP-15484, MAP15497 and MAP-
15485) will be summarized descriptively using the arithmetic mean, standard deviation (SD), CV (%), 
median, minimum and maximum. Individual plasma concentration-time profiles of MM36 will be 
plotted on both a linear and a semi-logarithmic scale. Mean values will also be presented graphically.  
The following pharmacokinetic parameters will be analyzed for each subject and for each PK time point 
at which a sufficient (detectable) concentration of MM36 or its metabolites will be measured to permit 
their derivation. If there are sufficient concentration data above the level of quantification the following 
pharmacokinetic parameters will be calculated:
Cmax = Maximum plasma concentration;
Tmax = Time of maximum plasma concentration;
AUC0-last = Area under the plasma concentration-time curve from time zero to time last (time 
of last quantifiable plasma concentration) [AUC0-t].
Safety
Safety evaluations will consist of adverse events (AEs), application site reactions, physical examinations, 
vital signs, ECGs, weight, and laboratory measurements (hematology, chemistry, and urinalysis). Full 
details will be specified in the SAP. 
Exploratory
Study Duration
The maximum individual study participation is approximately 60 days (screening (Day -30) through final 
Day 29 (± 1 day) Visit).

INTRODUCTION
2.1 Background Information 
MM36 (also known as OPC-271 and OPA-15406) is a novel nonsteroidal phosphodiesterase 
type 4 (PDE4) inhibitor which selectively inhibits the synthesis of the intracellular second 
messengers that activate inflammation
2.2 Rationale  
Currently, the pathogenesis of AD is unknown; however, Hanifin et al reported increased 
PDE activity and decreased intracellular cAMP levels in peripheral blood leukocytes of 
subjects with AD, which has been associated with higher production of proinflammatory 
mediators (Hanifin et al., 1985). Cooper et al reported the inhibition of immunoglobulin E 
synthesis with the PDE inhibitor, Ro 20-1724, in a study using the peripheral blood 
mononuclear cells of subjects with AD (Cooper et al., 1985).  These studies have shown that 
PDE inhibitors exert an anti-inflammatory action by increasing the intracellular cAMP 
concentration, inhibiting the production of cytokines and chemical mediators, and inhibiting 
cellular activity. Due to these effects, PDE inhibitors, particularly Type-4, are thought to be 
useful for the treatment of allergic inflammatory diseases.

Phosphodiesterases (PDEs) are cyclic nucleotide-degrading enzymes associated with the 
conversion of cyclic adenosine 3’,5’-monophosphate (cAMP) to 5'-adenylic acid.  Type-4
phosphodiesterase (PDE4) is widely expressed in a variety of inflammatory cells.  PDE4 
activity promotes a pro-inflammatory response and increased PDE activity has been 
associated with increased cytokine production and an abnormally elevated immune response.

STUDY DESIGN
4.1 General Description
This multicenter, open-label study, will evaluate the pharmacokinetics, safety, tolerability, 
and the exploratory efficacy of MM36 1% ointment when applied twice daily for up to 4 
weeks in subjects 2 to < 18 years of age with atopic dermatitis, at the upper range of disease 
severity. This study will also evaluate the systemic availability of MM36 1% when applied 
topically under maximal use conditions.   
Following screening (within 30 days prior to the first dose of study drug) and confirmation of 
study qualification, subjects will be registered and assigned (V2) to one of three treatment 
groups based on the subject’s age at Screening (V1). The first dose of study drug will be 
applied in the study clinic (V2/Day 1) and blood samples will be collected for evaluation of 
PK prior to the first application (0 hours) and at 1 hour (± 15 minutes), 4 hours (± 30 
minutes) and at 8 hours (± 1 hour) after application of study drug. On Day 15, the study drug 
will again be applied in the study clinic, and blood samples will be collected for PK prior to 
dosing and at 1 hour (± 15 minutes), 4 hours (± 30 minutes) and at 8 hours (± 1 hour) after 
application of study drug.  
At Screening (V1) and Baseline (V2), subjects with atopic dermatitis that are 2 to less than 
12 years of age (Group 2 and 3) must have a treatable area comprising
BSA
involvement (excluding scalp and venous access areas), and subjects 12 years of age and 
older (Group 1) must 
vement (excluding scalp and venous access 
areas) (i.e., maximal use conditions). The same (or greater, BSA if area involved expands) 
amount of study drug topically applied at baseline will continue to be applied twice daily, to 
the same area where study drug was applied on Day 1, even if the % BSA improves over the 
course of the first 2 weeks (14 days) of treatment. Between Day 15 (after the maximal use 
application and collection of PK samples) and Day 28, the study drug will only be applied to 
the involved areas. The last application of study drug will be given the evening before the 
final visit (V6). Refer to Figure 1.
An independent Data Safety Monitoring Board (DSMB) will facilitate the management and 
identification of potential safety concerns, on a regular basis, that could affect the safety of 
trial subjects, and will examine whether the information collected during these periodic 
intervals is consistent with knowledge about the product’s safety (e.g., unanticipated adverse 
events). The DSMB will also assess whether revisions to the study protocol and/or consent 
are required, and will evaluate the overall progress of the study. Details regarding the policies 
and procedures of the DSMB and intervals and data to be evaluated will be described in the 
DSMB Charter.

4.2 Enrollment  
A subject is considered enrolled in the study when the subject’s parent(s)/legal guardian(s)
has provided written informed consent and the child/adolescent has provided assent (as 
applicable). 
4.3 Registration 
Following verification that the subject meets all inclusion criteria and none of the exclusion 
criteria (V1), the subject will be scheduled for Visit 2 (Day 1). A subject who continues to 
meet all inclusion and no exclusion criteria will be registered, and study drug will be 
dispensed.  
4.4 Screen Failure
A subject who has been enrolled but subsequently fails to meet enrollment criteria prior to 
receipt of study drug will be deemed a screen failure. 
4.5 Completion
Each subject will participate in the study up to a maximum of 8 weeks, from the time the 
informed consent form (ICF) is signed/assent provided (V1) through the final visit (V6/Week 
4). A subject is considered to have completed the study after he/she has completed V6/Day 
29.
4.6 Early Termination (ET) 
A subject or the subject’s parent/legal guardian may withdraw the subject from treatment or 
from the study at any time at their request or may be withdrawn at any time at the discretion 
of the Investigator or Sponsor for safety, behavioral, or administrative reasons.

4.6.1 Criteria for Premature Discontinuation
4.6.1.1
Discontinuation from Treatment
A subject must be permanently discontinued from the study drug for any of the following 
reasons:
The subject becomes pregnant;
Allergic or adverse reaction to the study drug;
Clinically significant adverse event, which in the opinion of the Investigator, or 
DSMB, would put the subject at unnecessary risk if dosing was continued; or
The subject’s atopic dermatitis worsens and requires alternative or supplemental 
medication during the study.
If a subject is discontinued from treatment, they should continue to be followed in the study.
If subject refuses to stay in the study, then they will be encouraged to complete the V6 (Week 
4/ET visit).
4.6.1.2
Discontinuation from Study
A subject must be discontinued from the study drug and from the study for the following 
reason:
The subject withdraws consent. From the time consent is withdrawn, no additional 
data should be collected. However, the Sponsor may retain and continue to use data 
collected before such withdrawal of consent. 
A subject may be discontinued from the study drug or from the study for the following 
reason:
The subject requests withdrawal from the study. For the safety of the subject, if 
withdrawal is requested, the subject should be encouraged to complete the Week 
4/ET study procedures.
4.6.1.3
Lost to Follow-up
A subject is considered to have been lost to follow-up if he/she [subject or parent/legal 
guardian] cannot be contacted by the Investigator (or designee). The Investigator (or 
designee) will document efforts to attempt to reach the subject twice by telephone and will 
send a certified letter before considering the subject lost to follow-up.  The end of 
participation for a subject lost to follow-up is documented as the delivery date of the certified 
letter.
4.6.1.4
Subject Replacement
Subjects who prematurely discontinue and do not have at least three samples collected on 
either Day 1 or Day 15 post study drug application, may be replaced. The Sponsor may also 

Medimetriks Pharmaceuticals Inc.

Page 30 of 92
replace subjects who prematurely discontinue at their discretion or at the recommendation of 
the Data Safety Monitoring Board (DSMB). 
4.7 Safety Oversight
4.7.1 Data Safety Monitoring Board (DSMB)
An independent DSMB will be assembled and will facilitate the management and 
identification of potential safety concerns. The DSMB will also assess whether revisions to 
the study protocol and/or consent are required, and will evaluate the overall progress of the 
study.  Details regarding the DSMB will be further described in the study specific DSMB
Charter.
4.7.2 Investigator
The Principal Investigator must have access and be available to promptly review the results 
of all safety assessments (i.e., clinical laboratory testing), electrocardiogram (ECG) results, 
vital signs and adverse events (AEs) including application site assessment information 
throughout the study. Safety assessments must be promptly (should be within 48 hours of 
notification of event) entered into the Electronic Data Capture (EDC) system. Clinical 
laboratory data will be evaluated by the Principal Investigator and clinical relevance will be 
assessed for abnormal values and the assessment will be documented on the laboratory 
report. A copy of the reports will be maintained as part of the source documentation.

6.1.1 Written Parental/Legal Guardian Consent
Adequate provisions must be made for soliciting the permission of the child/adolescent’s 
(less than 18 years of age) parent(s) or legally authorized representative/guardian. The 
process for obtaining oral and/or written consent for children and adolescents is similar to 
that of obtaining consent for adults.  An effective informed consent process involves at 
minimum these elements:   
Conducting the process in a manner and location that ensures privacy;
Giving adequate information about the study in a language understandable to the 
parent/legal guardian and child/adolescent;
Providing adequate opportunity for the parent/legal guardian and child/adolescent to 
consider all options;
Responding to the parent(s)/legal guardian(s) and child/adolescent’s questions;
Ensuring the parent/legal guardian and child/adolescent has understood the 
information provided;
Obtaining the parent/legal guardian and child/adolescent voluntary agreement to 
participate, and 
Continuing 
to 
provide 
information 
as 
the 
parent(s)/legal 
guardian(s),
child/adolescent, or research requires.
6.1.2 Minimum Federal Requirements for Consent
The minimum United States (U.S.) federal requirements for consent indicated below should
be met. However, the Investigator or the Institutional Review Board (IRB)/Ethics Committee 
(EC) may determine that more stringent requirements are appropriate.

the custody of the child.
6.1.3 When Parents/Legal guardians Disagree   
If there are two parents/legal guardians available to give permission but they disagree about 
allowing their child to participate in the study, the child may not be enrolled unless that 
disagreement can be resolved. This applies to all permissible categories, even if only one 
parent’s signature is required, when both parents are involved in the decision, they must 
agree for the child to be enrolled. If a parent who was not involved or available for the 
original consent later becomes involved or available, the two parents must then agree.
6.1.4 Assent
The Investigator should carefully consider and propose adequate provisions for obtaining 
assent of children and adolescents prior to their participating in research. The approving 
IRB/EC application should address whether the intended subject population of children 
would be capable of understanding the nature of their participation in the research, and if so, 
whether or how assent will be obtained.  In determining whether a child is capable of 
assenting, their age, maturity, and psychological state should be taken into account. In 
may be made for all children and adolescents to be involved in research under a particular 
protocol, or for each child, as appropriate. An assent process that takes into account the 
child’s experience and level of understanding, assures an element of cooperation and a 
feeling of inclusion on the part of the child, and also illustrates the Investigator’s respect for 
the rights and dignity of the child in the context of research.   The child should be provided 
with essential information and asked whether or not they wish to participate in the research 
study. 
6.1.5 Documenting the Consent/Assent Process
Consent/Assent MUST be obtained and documented PRIOR to initiation of any study 
procedures. Additionally, the consent form approved for use by the IRB/EC will either 
contain language regarding subject confidentiality, the Health Insurance Portability and 
Accountability Act (HIPAA) or a separate form will also be signed as required by local law
(as applicable).  The PI or his/her approved designee must explain the nature of the study and 
associated risks to the parent(s)/legal guardian and study subject. The date/time that the 
informed consent is signed, a brief description of the consent/assent process (e.g., questions 
asked by the subject), and the name of the individual who obtained consent will be recorded 
in the source record. A copy of the signed informed consent should be provided to the 
parent(s)/legal guardian. Depending on the approving IRB and local requirements, an assent 
form may be included as part of the consent and may or may not be required to be signed by
the child. Investigators must adhere to their local requirements for proper documentation of 
consent/assent. A summary of assent procedures for execution of this study must be 
maintained in the Investigator Essential Regulatory File. It is the responsibility of the PI to 
ensure that any individual delegated the responsibility for obtaining consent/assent are

6.3.3 Medication History 
Medications taken within the last 2 months (60 days) prior to screening will be recorded in 
the source document and on the eCRF. Also refer to Section 6.23.5 concomitant medications 
for additional information.
6.4 Physical Examination
The physical examination will also include an examination of general appearance, skin, eyes, 
ears, nose, throat, neck/thyroid, lungs, heart, upper/lower extremities, lymph nodes, 
abdomen, musculoskeletal system and basic neurological assessment. Additional systems 
will be evaluated as needed. Physical exam findings must be recorded in the source 
documentation and include the date and name of the individual conducting the examination. 
Physical examinations must be performed by an individual licensed to conduct standard 
physical examinations.
Significant findings that are present prior to dosing with the study drug will be recorded in 
the eCRF as adverse events. Clinically significant findings present after dosing will be 
recorded as an adverse event in the eCRF.

6.6 Height/Weight and Body Mass Index (BMI) Calculation
Height (cm) and weight (kg) should be obtained with shoes off and only light clothing.
Scales should be calibrated and the same scale should be used for each weight assessment. 
Body Mass Index (BMI) will be calculated by dividing the weight (kg) by the height squared 
(cm) and will be obtained at Screening (V1). 
6.7 Body Surface Area (BSA) Calculation 
The Mosteller Formula (Mosteller, 1987) will be utilized to assess the overall BSA of each 
subject in this study utilizing height and weight collected at Screening (V1).

6.8 Body Surface Area (BSA)% Involvement
The BSA% involvement is the numerical area of active atopic dermatitis disease assessed by 
the Investigator at Screening (V1) and confirmed at Baseline (V2). One back-of-hand of the 
subject (palms and fingers) is equivalent to approximately 1% of a subject’s BSA. All 
eligible subjects 2 to less than 12 years of age must have a BSA% involvement (affected 
area/treatable area) of
35% (excluding scalp and venous access areas) and subjects 
years of age must 
(excluding scalp and venous access 
areas). The BSA% affected score may increase or decrease in area (i.e., size/shape) during 
the duration of the study and should be recorded in the source document and the eCRF. The 
BSA% involvement should be calculated by a qualified physician. 
6.9 Selected Treatment Area and BSA% to be Treated
6.9.1 Maximal Use Treatment Area  
The selected treatment area is defined as the collective areas selected for treatment in the 
study and it must be identified by the Investigator. At Baseline (V2) subjects 2 to less than 
12 years of age must have BSA% involvement (affected area
(excluding scalp and 
venous access areas)
25% BSA% (excluding scalp and venous access areas). Once the selected treatment area is 
set at Baseline, it may increase in area during the duration of the study (for expanded 
disease), but will not decrease in area during the first 2 weeks (14 days) of treatment (through 
collection of the Day 15 PK samples).

Page 41 of 92
6.9.2 Treatment for Improvement in Selected Treatment Area 
In order to assess the pharmacokinetic profile of MM36 1% (w/w) under maximal use 
conditions, all originally involved BSA treated with study drug at Baseline will continue to 
be treated with MM36 1% ointment even if the area has cleared until after the PK samples 
have been collected on Day 15.  On Day 15, the proportion of the treatment area will be 
defined as either involved or normal (cleared) skin and will be recorded in the source and 
eCRF.
6.9.3 Treatment for Worsening Selected Treatment Area
If the selected treatment area worsens, the Investigator will evaluate whether this worsening 
warrants withdrawal of the subject from study treatment.  Worsening is defined as a post-
baseline selected treatment area which requires additional study medication application due 
to an enlarged area of the BSA% involvement. If the worsening does not warrant 
discontinuation, the investigator will re-evaluate the selected treatment area and assess the
new BSA% treated and increase the ointment dispensing, as appropriate, to cover the 
increased BSA% affected.
The source document body diagram will require updating and a new copy will be provided to 
the subject/parent/guardian (caregiver) along with updated dosing/application instructions
(refer to Appendix A). 
6.10 Dosing Diary  
The subject/parent/guardian (caregiver) will be provided with an electronic dosing diary to 
record the time and amount of each study drug application. The importance of adherence to 
the study schedule will be reinforced at each study visit.

6.18 Application Site Assessment
The study drug application sites will be evaluated at each visit, preferably by the same 
assessor. The study drug should not be applied prior to the study visit to ensure accurate 
visualization of the areas of involvement. Skin irritation will be recorded as an adverse event 
and followed until resolution (or stabilization, as applicable).  Should a skin irritation event 
occur, patch testing is recommended to be performed, if feasible, to rule out an 
allergic/hypersensitivity event.
6.20 Photography  
Photographs of the lesions will be taken at the times presented in the schedule of
Assessments.  Selected sites will take standardized color photographs of the subject’s lesions.  
Photographic equipment and photography standards and procedures will be outlined in the 
photographic manual. All selected sites will be properly trained and instructions will be 
detailed in the Photographic Manual that will be provided.

6.21 Vital Signs
6.21.1 Temperature and Respiratory Rate
Temperature (oral or oral equivalent) and respiratory rate will be recorded once at each 
scheduled time point. Findings will be recorded in the source documentation and in the 
eCRF.
6.21.2 Seated Blood Pressure and Heart Rate
Blood pressure should be measured on the SAME arm (location should be documented) and 
with an appropriately sized (e.g., pediatric cuff) blood pressure cuff (that should be the same 
sized cuff throughout the study) for accurate comparison of readings over time.  Position is 
critical for accurate BP measurements. Therefore, when the BP is measured, the arm (cuff)
should be at the level of the heart. When seated, feet should be flat on the floor (if possible) 
with back supported and arm supported at the level of the heart (e.g., resting on a table). 
Blood pressure (systolic/diastolic) and heart rate will be assessed after the study subject has 
rested in a seated position for at least five (5) minutes. Blood pressure readings and heart rate 
readings will be measured in triplicate (approximately 1 minute apart) and the results will be 
recorded in the source document and eCRF along with the time they were taken.
It is important that vital signs be taken either before a meal, or at least 30 minutes after a 
meal or consuming caffeine. If the subject is a smoker, the subject must not be permitted to 
smoke within 30 minutes prior to scheduled study activities.
6.22 Electrocardiogram (ECG)
All investigative sites will be provided with an identical make/model calibrated portable 
ECG machine. Site personnel must assess the quality of the ECG while the subject is still at 
the investigative site in the event that additional ECGs need to be performed (i.e., if artifact is 
present). QT intervals will be reported uncorrected as well as corrected for heart rate 
according to the Fridericia Formula (QTcF).
For young children, the parent/parent/guardian (caregiver) should practice, prior to the study 
visit, lying still (starting with 5 seconds and work up to lying still for 1 minute [time to 
capture the ECG reading]). Suggest use of a timer to help the child understand how long to 
hold still. If possible, have the subject rest quietly for at least 10 minutes. Collection of the 
ECG should be considered for all subjects and this data will be read by a central core lab.
Refer to ECG manual for additional details regarding data collection and transmission.

6.23.2 Blood Volumes
Total blood volume (TBV) is related to body weight. The TBV of a child is about 75-80
mL/kg. Existing guidelines for blood sample volume limits (ranging from 1–5% of total 
blood volume within 24 hours and up to 10% of total blood volume over 8 weeks) are 
consistent with the limited evidence available on “minimal risk” to children (Howie, 2010). 
In this study, the smallest volume of blood will be collected for analysis of safety and PK. A
total of approximately 29.5 mL will be collected over the study period.
Blood samples are scheduled to be collected ten (10) times over the course of the study. 
Additional blood samples may be collected for evaluation of safety as clinically indicated. 
6.23.3 Sample Identification 
Blood samples will be labeled with the subject ID and initials and sample collection 
date/time and sample type.  The Sponsor will not have any information that would identify 
the study subject.
6.23.4 Screening and Safety Laboratory Testing
6.23.4.1 Pregnancy Testing
A pregnancy test is required for all female subj
or has reached 
menarche, whichever occurs first. A serum pregnancy test will be collected at Screening (V1) 
and must be negative. A urine pregnancy test will also be repeated at V2/Day 1. Additionally, 
a urine pregnancy test (local) will be done on the last study visit (V6/Day 29).
6.23.4.2 Routine Safety Laboratory Testing

6.24 Concomitant Medications
6.24.1 General
Use of chronic medications or as-needed medications (e.g., acetaminophen) will be permitted 
during the screening and active study period (unless otherwise restricted, refer to Section
6.24.2) and should be recorded in the source document and on the eCRF. Any changes in 
concomitant medication usage will be recorded in the source documents and on the eCRF. If 
the reason for change is related to an adverse event, the event should be recorded in the 
source documents and as an adverse event in the eCRF. 
Study medication and procedures which are not detailed in Table 2 will be allowed while the 
subject is in Screening (V1) and for the 4-week duration of the study (through V6), at the 
discretion of the Investigator, as long as they will not confound assessments of the treatment 
area.
The following concomitant medications, although not an exhaustive list of allowable 
medications, can be considered for use during the study treatment period, as long as 
reviewed/cleared by the investigator and have been at stable doses at the time of Screening 
and will be maintained at stable doses throughout the study period:
Intra-ocular or intra-nasal corticosteroids 
Intra-ocular or intra-nasal antihistamines
Inhaled corticosteroids/bronchodilators
Additional post-treatment (i.e., end-of-study) therapy, including medication to treat adverse 
events or atopic dermatitis, can be prescribed to the subject as needed, at the discretion of the 
investigator.
6.24.2 Concomitant Medication Restrictions
The following medications will not be permitted during the study period:
Medications (prescription and non-prescription) that are prohibited prior to Baseline (Visit 2)
and during study treatment are detailed in Table 2. The study treatment period is defined as

6.25 Prevention of Pregnancy during the Study
6.25.1 Instructions for Female Subjects of Childbearing Potential
Women who are pregnant or breastfeeding will not be allowed to participate in this study.
Females must either practice abstinence from heterosexual sexual contact or use one of the 
approved highly effective methods to prevent contraception that are described below. These 
methods should be followed from the time of consent/assent through the last dose of study 
drug. The Investigator will educate the subject regarding abstinence or contraception options 
and the correct and consistent use of effective contraceptive methods in order to successfully 
prevent pregnancy. 
Acceptable Method Option 1: Any one of the following methods may be used: hormonal 
contraception (oral, injection, implant, transdermal patch, vaginal ring); intrauterine device 
(IUD), tubal ligation: or partner’s vasectomy.
Acceptable Method Option 2: Male or female condom (latex condom or nonlatex condom 
NOT made out of natural [animal] membrane (e.g., polyurethane: PLUS, one additional 
barrier method: (a) diaphragm with spermicide; (b) cervical cap with spermicide; or (c) 
contraceptive sponge with spermicide.
Unacceptable Methods: Periodic abstinence (e.g., calendar, ovulation) or withdrawal.
6.25.2 Instructions to Males of Reproductive Potential
Due to unknown risks and potential harm to the unborn fetus, male subjects of reproductive 
potential (capable of impregnating their partner) who are sexually active with women of 
childbearing potential must use a reliable method of birth control while participating in this 
study. Refer to the acceptable methods listed above.
6.26 Lifestyle Guidelines
6.26.1
Restricted/Limited Exposure to Artificial/Natural Sunlight or Artificial 
Tanning Agents
Subjects must not use tanning beds, sunlamps, or artificial topical tanning materials, while 
participating in the study. Subjects should also avoid excessive unprotected exposure to 
sunlight from Screening (V1) through the final visit (V6), in order to reduce the risk of 
sunburn during the treatment period as this may confound the treatment area assessment, 
from Screening and for the 4-week duration of the study.

7.7 Unscheduled Visit(s) 
An unscheduled visit will be scheduled every 7 to 14 days in order to follow-up on 
unresolved adverse events that were still present at the final visit (V6). Additionally, the 
Study subject may be asked to return for additional visits to follow clinically significant 
abnormal laboratory results.  
7.8 Unscheduled Procedures
It may be necessary to collect unscheduled procedures as clinically indicated for evaluation 
of subject safety. Procedures completed at an unscheduled visit will be driven by the reason 
for the unscheduled visit. Should a skin irritation event occur, a patch testing can be 
performed, if feasible, to rule out an allergic/hypersensitivity event.

STUDY DOSING
8.1 Formulation, Packaging and Labelling  
8.1.1 Formulation 
MM36 1% is a white petrolatum based ointment. A list of all components in MM36 1%, is 
presented in Table 3.  Each gram of MM361 % w/w ointment contains 10 mg of active 
MM36. 
Table 3
Components of MM36 1%  
Components Ointment
MM36 1% w/w
8.1.2 Packaging 
Five labeled tubes will be assembled into a subject box. Each box will be labeled with a 
single panel label and tamper sealed. Five labeled subject boxes will be assembled into block 
kits. Each kit will be labeled with a 2-part tear away label and tamper sealed. 
8.2 Storage   
Study drug will be stored at the clinical site in a secured (limited access to authorized site 
personnel only) storage area. The investigational drug product will be stored at controlled 
room temperature (15°C to 25°C).   
8.3 Dispensing    
As reported in Nelson et al, 2006, “an average of 9.9 g/m2 (equivalent of 1.0 mg/cm2) of a 
topical agent (by weight) are required by a disciplined operator to achieve a thin, even layer 
of ointment on a patient” (pp. 224). Therefore, to determine the number of grams (by weight) 
per day, the Investigator/designee will use the following formula:

The table below (Table 4) is provided as general guide to determine the amount of study drug 
to be dispensed based on a subject’s BSA and their intended area of application. Exact 
calculation will be done on an individual basis. The Investigator or designee will enter the 
subject’s overall BSA, BSA% involvement and intended number of treatments (until the next 
visit) into the dosing module in the eCRF. The number of tubes to be dispensed will be 
calculated.

discussed with the subject or parent/guardian (caregiver) at the site and documented that 
proper training occurred prior to first application (refer to Appendix A).
8.4 Dosing
The subject (parent/guardian (caregiver) will be instructed on proper application of the study 
drug and will apply the initial application on Day 1 at the study site.  The proper dose 
dispensing procedure and use of the study drug will be demonstrated and observed by study 
staff to ensure subject (parent/guardian (caregiver) understand the instructions.   
For each dosing period, the subject, under the supervision of the parent/guardian 
(caregiver), or the parent/guardian (caregiver), will dispense the required amount of 
ointment (by weight) using the measuring cup(s) provided. 
The subject should wash his/her hands both before and after applying study ointment.  If 
applied by the parent/guardian (caregiver), they should also wash hands before and after 
applying study ointment, but will also wear non-latex gloves (provided by the Sponsor).  
The subject (parent/guardian (caregiver) will apply a thin layer of ointment to affected 
areas twice daily (approximately 12 hours apart) for 28 consecutive days.  
It is recommended that the ointment be applied after showering/bathing. The skin should 
be dry prior to application. Important: Subjects should not swim or bathe or wipe 
application area for a minimum of 20 minutes after application of ointment.
The ointment should be rubbed in gently and completely, avoiding contact with the eyes.  
Subject’s (parent/guardian (caregiver) will be instructed not to administer the study drug 
in the morning on the day of the study visit to avoid any effect of the study drug on the 
assessments.  
18 years of age) parent/guardian (caregiver) will verify if the study drug was 
weighed appropriately and applied as directed. Application details will be recorded in the 
electronic diary.
8.5 Compliance
The parent/guardian (caregiver)/subject will record the amount of drug used at each 
application and application location in the electronic diary. All used and unused study drug 
will be returned at all protocol-specified visits for study drug inventory and assessment of 
subject adherence.
The weight of the study drug will be measured before it is dispensed and after it is returned at 
Visit 3/Week 1, Visit 4/Week 2, Visit 5/Week 3 and Visit 6/Week 4.  Each dispensing and 
return of study drug as well as the weight of study drug will be documented in the eCRF.
The dispensing and return of all study drug will be recorded on the study drug dispensing 
log.  The subject number/initials and the initials and date of the person dispensing and 
receiving the returned medication will be documented on this form.

8.6 Study Drug Accountability
Inventory records must be readily available for inspection by the study monitor and/or 
auditor, and open to inspection by regulatory authorities at any time. Study drug will be 
received and dispensed by the designed study staff and returned to the Sponsor (unused study 
at completion of the study. All study drug will be accounted for on the study drug
inventory/accountability log and will include:
Subject ID and initials 
Date/time dispensed
Amount dispensed 
Amount remaining in inventory
Damaged or lost study drug will also be accounted for and recorded in the drug 
accountability records.
At completion of the study, the Investigator (or designee) is responsible for returning all 
unused study drug and used study drug containers to the Sponsor or representative, and must 
verify that no supplies remain in the investigator’s possession.

PROTOCOL VIOLATIONS
A protocol violation occurs when the study subject, Investigator, or Sponsor fails to adhere to 
significant protocol requirements affecting the inclusion, exclusion, study subject safety and 
primary endpoint criteria. Protocol violations for this study include, but are not limited to, the 
following:
Failure to meet inclusion/exclusion criteria
Dosing error
Failure to comply with Good Clinical Practice (GCP) guidelines will also result in a protocol 
violation. The Sponsor will determine if a protocol violation will result in withdrawal of a 
study subject or if data analysis will be censored.
When a protocol violation occurs, it will be discussed with the Investigator, and the details
will be documented and reviewed by the Sponsor representative and the Investigator. A copy 
of such documentation will be filed in the site’s regulatory binder and in the Sponsor’s files.

ADVERSE EVENTS
10.1 Definition of an Adverse Event
An adverse event is any untoward medical occurrence associated with the use of a drug in 
humans whether or not considered drug related.
An adverse event (also referred to as an adverse experience) can be any unfavorable and 
unintended sign (e.g., an abnormal laboratory finding), symptom, or disease temporally 
associated with the use of a drug, and does not imply any judgment about causality. An 
adverse event can arise with any use of the drug (e.g., off-label use, use in combination with 
another drug) and with any route of administration, formulation, or dose, including an 
overdose. 
10.2 General Guidelines
All observed or volunteered adverse events regardless of suspected causal relationship to the 
study drug are to be recorded on the appropriate eCRF from the time consent/assent is 
obtained through the end of the study as described in the following sections. 
For all adverse events, the Investigator (Principal Investigator or Sub-Investigator) must 
pursue and obtain information adequate both to determine the outcome of the adverse event 
and to assess whether it meets the criteria for classification as a serious adverse event 
requiring immediate notification to the Sponsor or designee. For all adverse events, sufficient 
information should be obtained by the Investigator to determine the causality of the adverse 
event. The Investigator (Principal or physician Sub-Investigator) is required to assess 
causality. For adverse events with a causal relationship to the study drug, follow-up by the 
Investigator (Principal or physician Sub-Investigator) is required until the event or its 
sequelae resolve or stabilize at a level acceptable to the Investigator (Principal or physician 
Sub-Investigator) and Medical Monitor concurs with that assessment.
10.3 Reporting Period
Serious adverse events require immediate notification to the Sponsor or designee, beginning 
from the time that the informed consent is signed, which is obtained prior to participation in 
the study, i.e., prior to undergoing any study-related procedure and/or receiving study drug,
through and including the day of the last dose of study drug or longer as applicable. Any 
serious adverse event occurring any time within the reporting period must be promptly 
reported if a causal relationship to investigational product is suspected. 
Adverse events (serious and non-serious) should be recorded on the eCRF from the time 
the study subject has signed informed consent (assent) through last study visit, unless 
otherwise specified.
Any changes in the subject’s status between enrollment (signing informed consent) up to 
the time of the first dose of study drug will be recorded as a pre-treatment adverse event 
and severity will be assessed. 

Medimetriks Pharmaceuticals Inc.
Protocol MEDI-MM36-206 Amended Protocol 1
Confidential
Page 64 of 92
Any adverse event occurring after the first dose of study drug will be considered a 
treatment emergent adverse event (TEAE). 
10.4 Assessment of Severity
Mild – An event that is usually transient in nature and generally not interfering with 
normal activities.
Moderate – An event that is sufficiently discomforting to interfere with normal activities.
Severe – An event that is incapacitating with inability to work or do usual activity or 
inability to work or perform normal daily activity.
10.5 Relationship of an Adverse Event to Study Drug
The investigator is to classify the relationship of an AE to the investigational product using 
good clinical judgment and the following definitions:
Relationship
Description
Not Related
The AE is clearly explained by another cause not related to the study product;
Probably Not Related
A potential relationship between study product and the AE could exist (i.e., the 
possibility cannot be excluded), but the AE is most likely explained by causes other 
than the study agent;
Possibly Related
The AE and administration of study product are temporally related, but the AE can be 
explained equally well by causes other than the study product;
Probably Related
The AE and use of study product are temporally related, and the AE is more likely 
explained by study product than by other causes;
Definitely Related
The AE and use of study product are related in time, and a direct association can be 
demonstrated.
The following factors should also be considered:
The temporal sequence from study medication administration: The event should occur 
after the study medication is given. The length of time from study medication exposure to 
event should be evaluated in the clinical context of the event.
Underlying, concomitant, intercurrent diseases: Each report should be evaluated in the 
context of the natural history and course of the disease being treated and any other 
disease the study subject may have.
Concomitant medication: The other medications the study subject is taking or the 
treatment the study subject receives should be examined to determine whether any of 
them might be recognized to cause the event in question.
Known response pattern for this class of study medication: Clinical and/or preclinical 
data may indicate whether a particular response is likely to be a class effect.
Exposure to physical and/or mental stresses: The exposure to stress might induce adverse 
changes in the recipient and provide a logical and better explanation for the event.

Medimetriks Pharmaceuticals Inc.
Protocol MEDI-MM36-206 Amended Protocol 1
Confidential
Page 65 of 92
The pharmacology and pharmacokinetics of the study medication: The known 
pharmacologic properties (absorption, distribution, metabolism, and excretion) of the 
study medication should be considered.
In the case of skin irritation, the results of any patch testing should be considered.  
10.6 Suspected Adverse Reaction
An adverse event for which there is a reasonable possibility that the drug caused the adverse 
event. For the purposes of Investigational New Drug safety reporting, “reasonable 
possibility” means there is evidence to suggest a causal relationship between the drug and the 
adverse event
10.7 Unexpected Adverse Events
An adverse event or suspected adverse reactions is considered “unexpected” if it is not listed 
in the investigator brochure (IB) or it is not listed at the specificity or severity that has been 
observed; or, if an IB is not required or available, is not consistent with the risk information 
described in the general investigational plan or elsewhere, as applicable. Unexpected, as used 
in this definition, also refers to adverse events or suspected adverse reactions that are 
mentioned in the IB or other applicable documentation as occurring with a class of drug or as 
anticipated from the pharmacological properties of the drug, but are not specifically 
mentioned as occurring with the particular drug under investigation.
10.8 Serious Adverse Event Definition
An adverse event or suspected adverse event reaction is considered serious if, in the view of 
either the Investigator or Sponsor, it results in any of the following outcomes:
Death;
A life-threatening adverse event;
NOTE: An adverse event or suspected adverse event is considered “life-
threatening” if, in view of either the Investigator or Sponsor, its occurrence places 
the study subject at immediate risk of death. It does not include an event that, had 
it occurred in a more severe form, might have caused death.
Requires hospitalization or prolongation of existing hospitalizations;
NOTE: Any hospital admission will be considered an inpatient hospitalization,
regardless of duration. An emergency room visit without hospital admission will 
not be recorded as an SAE under this criterion, nor will hospitalization for a 
procedure scheduled before signing of informed consent. However, unexpected 
complications and/or prolongation of hospitalization that occur during elective 
surgery should be recorded as adverse events and assessed for seriousness.
Admission to the hospital for a pre-planned procedure or social or situational 

Medimetriks Pharmaceuticals Inc.
Protocol MEDI-MM36-206 Amended Protocol 1
Confidential
Page 66 of 92
reasons (i.e., no place to stay, lives too far away to come for hospital visits) will 
not be considered inpatient hospitalizations.  
A persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions; 
A congenital anomaly/birth defect; or
Other important medical event (event that may jeopardize the patient or may require 
medical or surgical intervention to prevent one of the other outcomes listed in the 
definition above). 
NOTE: Important medical events that may not result in death, be life-threatening, 
or require hospitalization may be considered an SAE when, based upon 
appropriate medical judgment, they may jeopardize the study subject and may 
require medical or surgical intervention to prevent one of the outcomes listed 
above. Examples of such medical events include allergic bronchospasm requiring 
intensive treatment in an emergency room or at home, blood dyscrasias or 
convulsions that do not result in inpatient hospitalizations, or the development of 
drug dependency. 
10.9 Reporting
Each adverse event is to be assessed to determine if it meets the criteria for serious adverse 
event. If a serious adverse event occurs, expedited reporting will follow local and 
international regulations, as appropriate. 
All adverse events occurring from the time consent/assent is obtained through the end of the 
study will be reported on the adverse event page(s) of the eCRF. It should be noted that the 
form for collection of serious adverse event information is not the same as the adverse event 
CRF. Where the same data are collected, the forms must be completed in a consistent 
manner. For example, the same adverse event term should be used on both forms.  Adverse 
events should be reported using concise medical terminology on the eCRFs as well as on the 
form for collection of serious adverse event information. 
10.9.1 Serious Adverse Event Reporting Requirements
If a serious adverse event occurs, the Sponsor or designee is to be notified (see below) within 
24 hours of awareness of the event by the Investigator. In particular, if the serious adverse 
event is fatal or life-threatening, notification to the Sponsor or designee, must be made 
immediately, irrespective of the extent of available adverse event information. This 
timeframe also applies to additional new information (follow-up) on previously forwarded 
serious adverse event reports as well as to the initial and follow-up reporting of Pregnancy 
cases. A site designee will complete the Serious Adverse Event (SAE) Reporting Form and 
send the report(s), within 24 hours of learning of an initial SAE to 
with supporting documentation, if 
applicable.

Page 67 of 92
Medical Monitor
Serious Adverse Event (SAE) Reporting
In the rare event that the Investigator does not become aware of the occurrence of a serious 
adverse event immediately (e.g., if an outpatient trial study subject initially seeks treatment 
elsewhere), the Investigator is to report the event within 24 hours after learning of it and 
document the time of his/her first awareness of the adverse event.
For all serious adverse events, the Investigator is obligated to pursue and provide information 
to the Sponsor or designee, in accordance with the timeframes for reporting specified above.  
In addition, an Investigator may be requested by the Sponsor or designee to obtain specific 
additional follow-up information in an expedited fashion. This information may be more 
detailed than that captured on the adverse event case report form. In general, this will include 
a description of the adverse event in sufficient detail to allow for a complete medical 
assessment of the case and independent determination of possible causality.  Information on 
other possible causes of the event, such as concomitant medications and illnesses must be 
provided.  In the case of a study subject death, a summary of available autopsy findings must 
be submitted as soon as possible to the Sponsor or its designated representative. The 
Investigator must continue to follow the study subject until the SAE has subsided or until the 
condition becomes chronic in nature, stabilizes (in the case of persistent impairment) or the 
study subject dies. Within 24 hours of receipt of follow-up information, the Investigator must
update the SAE form and submit it to the Sponsor or Designee Safety Coordinator. 
10.9.2 Non-Serious Adverse Event Reporting Requirements and Ongoing Safety Review
Non-serious adverse events are to be reported in the eCRF which will be reviewed by the 
Sponsor or designee Medical Monitor on an ongoing basis. 
10.10 Pregnancy Reporting
If a study subject becomes pregnant during the study, the Investigator should report the 
pregnancy to the Sponsor, or its representative, within 24 hours of being notified.  
The Pregnancy Report form must be completed by the site and sent within 24 hours of 
learning of a pregnancy to 
with supporting documentation, if applicable.   
The study subject should be followed by the Investigator until completion of the pregnancy. 
If the pregnancy ends for any reason before the anticipated date, the Investigator should 
notify the Sponsor. At the completion of the pregnancy, the Investigator will document the 
outcome of the pregnancy. If the outcome of the pregnancy meets the criteria for immediate 
classification as an SAE (i.e., postpartum complication, spontaneous abortion, stillbirth, 
neonatal death, or congenital anomaly), the Investigator should follow the procedures for 
reporting an SAE. Otherwise, a Pregnancy Outcome Report should be completed.

DATA ANALYSIS AND STATISTICAL METHODS
11.1 Sample Size Determination
The sample size is not driven by inferential statistics. A sample size of 32 subjects is set for 
qualitative investigation of the pharmacokinetic profile as well as the safety and tolerability 
and responsiveness (efficacy) of MM36 1% when applied topically twice daily for 4 weeks to 
pediatric subjects 2 to < 18 years of age.
11.2 Analysis Populations
Two populations will be used for analysis: safety and intent-to-treat. The definition of these 
populations follows:
Safety Population:  All enrolled subjects who received at least one dose of study 
medication and have at least one post-baseline safety assessment constitute the Safety 
Population.
Intent-to-Treat (ITT) Population:  All enrolled subjects who took at least one dose of 
study medication constitute the Intent-to-Treat Population.
Safety and PK data will be analyzed based on the safety population. Efficacy data will be 
analyzed based on the ITT population.
11.3 Statistical Analysis
11.3.1 General Statistical Methodology
All statistical processing will be performed using SAS® unless otherwise stated.
Continuous data will be summarized using descriptive statistics (number of values, mean, 
standard deviation, median, minimum and maximum). Categorical data will be 
summarized using frequency tables (frequencies and percent).
A statistical analysis plan (SAP), describing all statistical analyses will be provided as a 
separate document. The SAP will be finalized prior to locking the database. The SAP will 
contain any modifications to the analysis plan presented below.
11.3.2 Demographics, Medical History, Baseline Characteristics, and Concomitant 
Medications
Demographic data, medical history including history of acute dermatitis, and prior and 
concomitant medications will be summarized using descriptive statistics. 
11.3.3 Treatment Compliance
The Parent/guardian (caregiver)/Subject will record all applications made or missed in the 
electronic diary. Subject compliance during the overall treatment period and by visit will be 
summarized.

11.3.4 Drug Exposure
Amount of study drug (weight) and the number of days with study drug application will be 
summarized.
11.4
Primary Analysis
11.4.1 Pharmacokinetics
Individual plasma concentrations of MM36 and its metabolites (MAP-15484, MAP15497 
and MAP-15485) will be summarized descriptively using the arithmetic mean, standard 
deviation (SD), CV (%), median, minimum and maximum. Individual plasma concentration-
time profiles of MM36 will be plotted on both a linear and a semi-logarithmic scale. Mean 
values will also be presented graphically.  The following pharmacokinetic parameters will be 
analyzed for each subject and for each PK time point at which a sufficient (detectable) 
concentration of MM36 or its metabolites will be measured to permit their derivation. If there 
are sufficient concentration data above the level of quantitation the following 
pharmacokinetic parameters will be calculated:
Cmax = Maximum plasma concentration
Tmax = Time of maximum plasma concentration
AUC0-last = Area under the plasma concentration-time curve from time zero to time last 
(time of last quantifiable plasma concentration) [AUC0-t]
The pharmacokinetic analysis will be implemented in SAS®, and conducted using Non-
Compartmental Analysis (NCA) on plasma concentrations of MM36 in the subjects who will 
receive MM36 1% ointment and had evaluable plasma concentration-time profiles. PK 
parameters will be listed for all individuals. Descriptive summary statistics (number of 
observations (N), arithmetic mean, standard deviation (SD), CV%, median, minimum, 
maximum and geometric mean) will be reported for PK parameters. Individual elapse 
sampling time will be used in the pharmacokinetic analysis. Cmax and tmax will be obtained 
directly from the experimental observations. AUC(0-t) will be calculated using the linear 
trapezoidal rule.
BLQ (< 0.2 ng/mL) samples will be set to zero for the summary of the statistics for 
concentration values. For the purpose of the NCA, BLQ set to zero before tmax and missing 
after tmax.  Any quantifiable concentrations at pre-dose at Day 1 will be set to zero.
11.5 Secondary Analysis
11.5.1 Safety
Safety evaluations will consist of adverse events (AEs), application site reactions, physical 
examinations, vital signs, ECGs, weight, and laboratory measurements (hematology, 
chemistry, and urinalysis). Full details will be specified in the SAP.  A general description of 
the planned analysis is as follows:

Descriptive statistics and frequency tables will be prepared as appropriate for physical 
examinations, vital signs, weight, ECG (HR, QTcF, PR, and QRS) and laboratory 
measurements (hematology, chemistry, and urinalysis).
Adverse Events
o
AEs will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA); the version will be identified in the clinical study report.
o
AEs that occurred during the screening period will be listed separately and 
will not be included in the AE tabulations. 
o
All other AEs that start on or after first dose will be considered TEAEs. 
Summaries will be presented by system organ class and preferred term, and 
further by severity and relationship to study drug.  Application site AEs and 
any 
5% of subjects will also be tabulated.
o
The proportion of subjects who discontinue treatment due to an adverse event 
will be presented.
Concomitant medications will be classified according to the World Health Organization 
(WHO) Drug Dictionary and will be presented in data listings.

DATA COLLECTION, RETENTION AND MONITORING
12.1 Data Collection Instruments
The Investigator will prepare and maintain adequate and accurate source documents designed 
to record all observations and other pertinent data for each study subject treated with the test 
article. The Investigator is responsible for ensuring that data is properly entered into the 
electronic devices (diaries and site electronic devices) as this will serve as source 
documentation for certain scales, measures, dosing for the study.  Study personnel at each 
site will enter data from source documents corresponding to a study subject’s visit into the 
protocol-specific electronic Case Report Form (eCRF) when the information corresponding 
to that visit is available.  
Study subjects will not be identified by name in the study database or on any study 
documents to be collected by the Sponsor (or designee), but will be identified by a site 
number, study subject number and initials.
If a correction is required for an eCRF, the time and date stamps will track the person 
entering or updating eCRF data and creates an electronic audit trail. 
The Investigator is responsible for all information collected on study subjects enrolled in this 
study. All data collected during the course of this study must be reviewed and verified for 
completeness and accuracy by the Investigator.  Copies of final completed eCRFs will be 
provided on a compact disk (CD) or other similar media for archiving at the study site 
following database lock and at or prior to study closure.
12.2 Data Management Procedures
The data will be entered into a validated database.  The Data Management group will be 
responsible for data processing, in accordance with procedural documentation.  Database 
lock will occur once quality assurance procedures have been completed. All procedures for 
the handling and analysis of data will be conducted using good computing practices meeting 
FDA guidelines for the handling and analysis of data for clinical trials.
12.2.1 Data Quality Control and Reporting
After data have been entered into the study database, a system of computerized data 
validation checks will be implemented and applied to the database on a regular basis. Queries 
are entered, tracked, and resolved through the electronic data capture (EDC) system directly.  
The study database will be updated in accordance with the resolved queries.  All changes to 
the study database will be documented.
12.2.2 Data Entry
Data must be recorded using the EDC system as the study is in progress. All site personnel 
must log into the system using their secure user name and password in order to enter, review, 
or correct study data. These procedures must comply with Title 21 of the Code of Federal 
Regulations (21 CFR Part 11) and other appropriate international regulations. All passwords

will be strictly confidential. Data should be entered onto the eCRF approximately no later 
than 72 hours after the visit has taken place.
12.2.3 Medical Information Coding
For medical information, the following thesauri will be used:
Latest version of the Medical Dictionary for Regulatory Activities (MedDRA) for 
medical history and adverse events; and
World Health Organization Drug Dictionary (WHODD) for prior and concomitant 
medications.
12.2.4 Data Validation
Validation checks programmed within the EDC system, as well as supplemental validation 
performed via review of the uploaded data, will be applied to the data in order to ensure 
accurate, consistent, and reliable data. Data identified as erroneous, or data that are missing, 
will be referred to the investigative site for resolution through data queries.
The CRFs must be reviewed and electronically signed by the Investigator who signed the 
protocol.
12.3 Archival of Data
The database is safeguarded against unauthorized access by established security procedures; 
appropriate backup copies of the database and related software files will be maintained.
Databases are backed up by the database administrator in conjunction with any updates or 
changes to the database. At critical junctures of the protocol (e.g., production of interim 
reports and final reports), data for analysis is locked and cleaned per established procedures.
12.4 Availability and Retention of Investigational Records
The Investigator must make study data accessible to the monitor, other authorized 
representatives of the Sponsor (or designee), IRB/IEC, and Regulatory Agency (e.g., FDA) 
inspectors upon request.  A file for each study subject must be maintained that includes the 
signed Informed Consent, HIPAA Authorization and Assent Form and copies of all source 
documentation related to that study subject.  The Investigator must ensure the reliability and 
availability of source documents from which the information on the CRF was derived.
All study documents (patient and subject files, signed informed consent forms, copies of 
CRFs, Study File Notebook, etc.) must be kept secured for a period of two years following 
marketing of the investigational product or for two years after centers have been notified that 
the IND has been discontinued.  There may be other circumstances for which the Sponsor is 
required to maintain study records and, therefore, the Sponsor should be contacted prior to 
removing study records for any reason.

12.5 Monitoring
Monitoring visits will be conducted by representatives of the Sponsor (or designee) 
according to the U.S. CFR Title 21 Parts 50, 56, and 312 and ICH Guidelines for GCP (E6).  
By signing this protocol, the Investigator grants permission to the Sponsor (or designee), and 
appropriate regulatory authorities to conduct on-site monitoring and/or auditing of all 
appropriate study documentation.
12.6 Subject Confidentiality
In order to maintain study subject confidentiality, only a site number, study subject number 
and initials will identify all study subjects on CRFs, blood samples, and other documentation 
submitted to the Sponsor.  Additional study subject confidentiality issues (if applicable) are 
covered in the Clinical Study Agreement.
12.7 Retained Blood Samples
Blood samples collected during the study for pharmacokinetic analysis may be retained for 
future testing as necessary. Study subject’s confidentiality will be maintained and only the 
site and study subject number and initials will identify the sample. No other linked or 
identifying information is maintained by the Sponsor.

The study will be conducted according to the Declaration of Helsinki, Protection of Human 
Subjects (21 CFR 50), Institutional Review Boards (21 CFR 56), and Obligations of Clinical 
Investigators (21 CFR 312 Subpart D).
To maintain confidentiality, all laboratory specimens, evaluation forms, reports and other 
records will be identified by a coded number and initials only.  All study records will be kept 
in a locked file cabinet.  The Investigator must also comply with all applicable privacy 
regulations (e.g., Health Insurance Portability and Accountability Act of 1996, EU Data 
Protection Directive 95/46/EC).
13.1 Protocol Amendments
Any amendment to the protocol will be written by the Sponsor or Sponsor designee. Protocol 
amendments cannot be implemented without prior written IRB/IEC approval except as 
necessary to eliminate immediate safety hazards to study subjects/patients.  A protocol 
amendment intended to eliminate an apparent immediate hazard to study subjects/patients 
may be implemented immediately, provided the IRBs are notified within five working days.
13.2 Institutional Review Boards and Independent Ethics Committees
The protocol and consent form will be reviewed and approved by the IRB/IEC of each 
participating center prior to study initiation.  Serious adverse experiences regardless of 
causality will be reported to the IRB/IEC in accordance with the standard operating 
procedures and policies of the IRB/IEC, and the Investigator will keep the IRB/IEC informed 
as to the progress of the study. The Investigator will obtain assurance of IRB/IEC compliance 
with regulations.
Any documents that the IRB/IEC may need to fulfill its responsibilities (such as protocol, 
protocol amendments, Investigator’s Brochure, consent forms, information concerning 
subject/patient recruitment, payment or compensation procedures, or other pertinent 
information) will be submitted to the IRB/IEC. The IRB/IECs written unconditional approval 
of the study protocol and the informed consent form will be in the possession of the 
Investigator before the study is initiated.  The IRB/IECs unconditional approval statement 
will be transmitted by the Investigator to the Sponsor prior to the shipment of study supplies 
to the site.  This approval must refer to the study by exact protocol title and number and 
should identify the documents reviewed and the date of review.
Protocol and/or informed consent modifications or changes may not be initiated without prior 
written IRB/IEC approval except when necessary to eliminate immediate hazards to the 
subjects/patients or when the change(s) involves only logistical or administrative aspects of 
the study.  Such modifications will be submitted to the IRB/IEC and written verification that 
the modification was submitted and subsequently approved should be obtained.  
The IRB/IEC must be informed of revisions to other documents originally submitted for 
review; serious and/or unexpected adverse experiences occurring during the study in 
accordance with the standard operating procedures and policies of the IRB; new information

that may affect adversely the safety of the subjects/patients of the conduct of the study; an 
annual update and/or request for re-approval; and when the study has been completed.
13.3 Informed Consent Form – General Provisions
Informed consent will be obtained in accordance with the Declaration of Helsinki, ICH GCP, 
US Code of Federal Regulations for Protection of Human Subjects (21 CFR 50.25[a,b], CFR 
50.27, and CFR Part 56, Subpart A), the Health Insurance Portability and Accountability Act 
(HIPAA, if applicable), and local regulations. Also refer to Protocol Section 6.1.
The Investigator will prepare the informed consent form, assent and HIPAA authorization 
and provide the documents to the Sponsor or designee for approval prior to submission to the 
IRB/IEC.  The consent form generated by the Investigator must be acceptable to the Sponsor 
and be approved by the IRB/IEC.  The written consent document will embody the elements 
of informed consent as described in the International Conference on Harmonization and will 
also comply with local regulations. The Investigator will send an IRB/IEC-approved copy of 
the Informed Consent Form to the Sponsor (or designee) for the study file.
A properly executed, written, informed consent will be obtained from each study subject or 
the subject’s legally authorized representative prior to entering the study subject into the trial 
and conducting any Screening visits.  Information should be given in both oral and written 
form and study subjects (or their legally authorized representatives) must be given ample 
opportunity to inquire about details of the study.  If appropriate and required by the local 
IRB/IEC, assent from the study subject will also be obtained.  If a study subject is unable to 
sign the informed consent form (ICF) and the HIPAA authorization, a legal representative 
may sign for the study subject.   A copy of the signed consent form (and assent) will be given 
to the study subject or legal representative of the study subject and the original will be 
maintained with the study subject’s records.
13.4 Publications 
The preparation and submittal for publication of manuscripts containing the study results 
shall be in accordance with a process determined by mutual written agreement among the 
study Sponsor and participating Investigators.  The publication or presentation of any study 
results shall comply with all applicable privacy laws, including, but not limited to, the Health 
Insurance Portability and Accountability Act of 1996.
