 Synopsis 
Name of Sponsor/Company: 
Dow Pharmaceuticals Sciences, a Division of Valeant Pharmaceuticals North America, LLC 
Name of Investigational Product: 
IDP-124 Lotion 
Name of Active Ingredient:  
Pimecrolimus, 1% 
Title of Study: 
A Multicenter, Randomized, Double-Blind, Vehicle-Controlled, Study to Evaluate the Efficacy and Safety of 
IDP-124 Lotion for the Treatment of Moderate to Severe Atopic Dermatitis in Pediatric and Adult Subjects 
Number of Clinical Centers: 
Approximately 20 investigational centers in North America and Latin America 
Objectives:  
The objectives of this study are to evaluate the efficacy, safety, and tolerability of IDP-124 Lotion for the 
treatment of moderate to severe atopic dermatitis (AD) in pediatric and adult subjects, 2 years of age and 
older.  
Methodology: 
This is a multicenter, randomized, double-blind, parallel group, vehicle-controlled study to evaluate treatment 
success using a 5-point Investigator Global Assessment (IGA) scale from clear to severe; the improvement of 
Eczema Area Severity Index (EASI); improvement in total affected body surface area (TBSA); assessment of 
pruritus (itching) and sleep disturbance; Patient-Oriented Eczema Measure (POEM) from subjects and 
parents/legal guardians of pediatric subjects; and investigator’s assessment of signs and symptoms of AD. 
The study consists of a 6-week double-blind treatment period and 4-week post-treatment follow-up. Study 
visits include Screening, Baseline, and Weeks 1, 2, 4, 6, and 10 (subjects will return to the clinic at Week 10 
for a post-treatment follow-up visit). At the Screening Visit, subjects or their parents/legal guardians (when 
applicable) will sign an informed consent/assent form, provide their medical histories, report their previous 
and concomitant medications/therapies, and be evaluated against the inclusion/exclusion criteria. For all pre-
menses females (9 and older) and females of childbearing potential (FOCBP), urine pregnancy tests will be 
performed at specified visits. An abbreviated physical exam will be performed, vital signs measured (sitting 
blood pressure, respiration, pulse, and temperature), and blood and urine specimens will be collected for serum 
chemistry, hematology, and urinalysis evaluations (and serum pregnancy for all pre-menses females [9 and 
older] and females of childbearing potential). During this visit, the investigator will perform the IGA, evaluate 
the subject for TBSA affected by AD, and assess the subject for other signs and symptoms of AD. 
At the Baseline Visit, prior to being evaluated by the investigator and study staff, subjects or parents/legal 
guardians (if applicable) are to complete the POEM. At this visit, medical histories and concomitant 
medication /therapy use will be updated, and the inclusion/exclusion criteria will be confirmed. Adverse 
events since the Screening Visit will be assessed, and all pre-menses females (9 and older) and FOCBP will 
have urine pregnancy tests performed. During the Baseline Visit, the IGA, EASI, Pruritus and Sleep 
Disturbances assessment, and Subject Assessment scale will be completed, and the investigator will evaluate 
the subject for other signs and symptoms of AD.

After confirming eligibility at the Baseline Visit, subjects will be randomized using the interactive response 
technology (IRT) in a 2:1 ratio to receive either IDP-124 Lotion or IDP-124 Vehicle Lotion. Randomized 
Subjects or parents/legal guardians of pediatric subjects will apply the first administration of the assigned 
study drug to the affected areas of the skin (as identified in a body diagram in the source documentation) at the 
investigational center under the supervision of designated study personnel. Subjects will receive the study drug 
and given verbal and written instructions for treatment application. Specifically, the subjects will be instructed 
to apply the lotion to the affected areas twice daily, at approximately the same time each day, 12 hours apart. 
The subjects will also receive diaries, with instructions to complete a record of all applications and to note any 
missed applications of the study drug. In addition, at selected sites, standardized photography will be 
performed at Baseline and Weeks 2, 4, 6 and 10.  
Throughout the study, safety will be assessed by reviewing the occurrence of adverse events (AEs), assessing 
vital sign measurements and abbreviated physical examination findings, and noting any additions or changes 
in concomitant medication uses. Blood and urine samples will be collected at Screening and Week 6 visits for 
routine safety laboratory evaluations (and serum pregnancy for pre-menses females [9 and older] and 
FOCBP); and urine pregnancy tests will be obtained for all pre-menses females (9 and older) and FOCBP at 
each study visit (with the exception of Week 1). Efficacy assessments of the IGA, EASI, Pruritus and Sleep 
Disturbances, TBSA affected by AD, Subject Assessment, and evaluation for signs and symptoms of atopic 
dermatitis will be performed throughout the study. In addition, the POEM will be completed by the 
subjects/parents/legal guardians at Week 6 and Week 10.   
Number of Subjects Planned:  
Approximately 348 subjects will be randomized 2:1 to the following treatment groups: 
 
232 subjects to IDP-124 Lotion, twice daily application 
 
116 subjects to IDP-124 Vehicle Lotion, twice daily application

Investigational Product, Dosage, and Mode of Administration:  
Investigational Product and Dosage: IDP-124 Lotion (Pimecrolimus, 1%) 
Mode of Administration: Subjects and parents/legal guardians, when applicable, will be instructed to apply 
the study drug as a thin layer twice daily at approximately the same time each day and 12 hours apart to 
affected areas of the skin (see Appendix 17.1 for subject and parent/legal guardian instructions). The first 
administration of the assigned study drug will be applied to the affected areas of the skin at the investigational 
center at the Baseline visit, under the supervision of designated study personnel. Study drug will continue to 
be applied for the duration of the 6-week treatment period even if complete clearing of the affected areas is 
observed. On study visit days, subjects will apply one dose of study drug at the investigational site. 
New areas of the skin that become affected during the study may be treated with study drug. The subject or 
parent/legal guardian may begin study drug application to new lesion/s without the investigator’s 
confirmation, and must inform the investigator of new lesion treatment at their next study visit.  
Bland emollients, such as CeraVe®, Eucerin®, or Aquaphor®, may be applied during the study at the discretion 
of the subject and/or parent/legal guardian, and investigator. Appendix 17.2 provides an example list of 
allowable bland emollients to be used during the study. Subjects will be instructed to apply the emollient (if 
needed) 20-30 minutes after study drug application. If subjects have been using bland emollients during the 
Screening period, they will be reminded to refrain from use on the morning prior to the Baseline Visit  
Subjects may gently wash (e.g., take a bath or shower) the areas of treatment shortly before the application of 
study drug. Subjects should allow the skin to dry completely before application of the study drug. After 
application, the treated skin should not be washed for at least 3 hours.  
Subjects will be instructed to record study drug treatment of affected areas identified at Baseline, new lesions 
during the study (if applicable), and bland emollient applications (if applicable) in the study diary each day.  
Duration of Treatment:  
6 weeks, twice daily 
Reference Therapy, Dosage and Mode of Administration:

Safety: 
Safety and tolerability will be assessed throughout the study:   
- 
Monitoring of AEs will be conducted at each study visit.  
- 
Routine clinical laboratory results (hematology, serum chemistry, urinalysis, and serum pregnancy 
testing for pre-menses females [9 and older] and FOCBP), vital sign measurements (sitting blood 
pressure, respiration, pulse, and temperature), and abbreviated physical examination findings, will be 
conducted at Screening and Week 6 study visits.  
- 
Urine pregnancy tests (FOCBP, females 9 and older) will be conducted throughout the study (with 
the exception of Week 1). If a subject becomes pregnant during the treatment period, the study drug 
will be discontinued immediately, the subject will be discontinued from the study, and the 
investigator will notify the sponsor. The pregnancy will be followed to term with the outcome 
reported to the sponsor.  
Subjects will be followed for 4 weeks after either completion or early discontinuation from the study to assess 
those AEs ongoing at the time of study completion or leading to discontinuation. Description of AEs will 
include the dates of onset and resolution (if resolved), maximum severity, seriousness, action taken regarding 
the study drug, corrective treatment, outcome, and the investigator’s assessment of causality. Any out-of-range 
laboratory result that is considered clinically significant by the investigator will be recorded as an AE and 
should be confirmed by repeat testing at the discretion of the investigator. Clinically significant laboratory 
abnormalities at any visit will be followed to resolution (return to normal or to the baseline state) or until 
clinically stable as determined by the investigator.

Statistical Methods:  
All statistical processing will be performed using SAS® unless otherwise stated. No interim analyses are 
planned. Except where noted, all statistical tests will be two-sided and will be performed at the 0.05 level of 
significance. 
Descriptive statistics will be used to provide an overview of the efficacy and safety results. For categorical 
parameters, the number and percentage of subjects in each category will be presented. For continuous 
parameters, descriptive statistics will include n (number of subjects), mean, standard deviation, median, 
minimum, and maximum. Appropriate inferential statistics will be used for the primary, secondary, and 
tertiary efficacy variables. 
The primary method of handling missing efficacy data will be the method of Markov Chain Monte Carlo 
multiple imputation. As a sensitivity analysis, the last observation carried forward method will be used (ie, the 
last available on-therapy observation for a subject will be used to estimate subsequent missing data points). 
Additionally, a tipping point analysis will be performed for the primary endpoint. No imputations will be made 
for missing safety data. 
A statistical analysis plan (SAP), describing all statistical analyses will be provided as a separate document. 
The SAP will be finalized prior to unblinding of the study treatments. 
Primary efficacy analysis: The primary efficacy endpoint will be used to compare twice daily application of 
IDP-124 Lotion and Vehicle Lotion. The percentage of subjects with treatment success at Week 6 will be 
analyzed using Cochran-Mantel-Haenszel (CMH) test stratified by analysis center.  
Secondary efficacy analysis: Comparisons of secondary endpoints, will be performed using CMH tests 
stratified by analysis center. Evaluation of the secondary efficacy variables will use a gated sequential 
procedure starting with the comparisons in the predefined order as listed above.  The process will terminate if 
a nonstatistically significant value is observed. 
Tertiary efficacy analysis: For tertiary efficacy endpoints, all but the mean percent change from Baseline in the 
affected TBSA will be analyzed with the CMH test stratified by analysis center. The analysis of TBSA will 
use an Analysis of Covariance with factors of treatment and analysis center and a covariate of the Baseline 
TBSA score. Analyses of tertiary endpoints will be performed without adjusting for multiplicity. 
Efficacy analyses will be performed using the intent-to-treat (ITT) population, the Week 6 per protocol (PP) 
population, and the Week 10 PP population. The ITT analysis set will be considered primary for the evaluation 
of efficacy. Safety analyses will be performed using the safety population. 
All subjects who are randomized and dispensed study drug will be included in the ITT population. 
All subjects who are randomized and receive at least 1 confirmed dose of study drug will be included in the 
safety population.

All subjects in the ITT population who complete the Week 6 visit without any major protocol violations will 
be included in the Week 6 PP population. The Week 6 PP population will include subjects in the ITT 
population who do not meet any of the following criteria: 
 Violated the inclusion/exclusion criteria; 
 Used an interfering concomitant medication prior to Week 6; 
 Did not attend the Week 6 visit; 
 Missed more than 1 post baseline study visit prior to Week 6; 
 Have not been compliant with the dosing regimen (i.e., subjects must apply 80% - 120% of the 
expected applications of study medication during participation in the study); 
 Out of visit window at the Week 6 visit by more than ± 5 days 
Subjects who discontinue from the study due to an adverse event related to study treatment or documented 
lack of treatment effect (and/or worsening of condition) will be included in the Week 6 PP population.  
 
All subjects in the Week 6 PP population who complete the Week 10 visit without any major protocol 
violations will be included in the Week 10 PP population. Specifically, the Week 10 PP population will 
include subjects in the Week 6 PP population who did not meet any of the following criteria:  
 Used an interfering concomitant medication between Week 6 and Week 10  
 Did not attend the Week 10 visit  
 Out of visit window at the Week 10 visit by more than ± 5 days  
Subjects that discontinue from the study due to an adverse event related to study treatment or documented lack 
of treatment effect will be included in the Week 10 PP population. 
Prior to breaking the blind, other additional criteria may be added to the list to accommodate for unforeseen 
events that occurred during the conduct of the trial that result in noteworthy study protocol violations.
Sample Size Calculations: 
Power calculations were computed using the IGA efficacy results from the Pimecrolimus Cream, 1% (Elidel) 
New Drug Application 21-302. Considerations were given the change in expected entry level severity of the 
current study. Specifically, moderate to severe subjects enrolled in pivotal Elidel studies were used for 
analyses. Nquery Advisor Version 7.0 with the Fisher’s exact test option was used to calculate the power using 
a two-sided test with an alpha of 0.05. Overall, 232 IDP-124 Lotion-treated subjects and 116 Vehicle Lotion-
treated subjects will have greater than 95% power to detect a statistically significant outcome for a two-sided 
test with an alpha level of 0.05.

 Introduction 
Atopic dermatitis (AD) is a very common chronic dermatosis with a prevalence of 10% to 
20% in children and 1% to 3% in adults [1]; AD poses difficult therapeutic challenges and 
may have a profound effect on a patient’s quality of life. The disease gives rise to itching and 
severely dry skin, and is characterized by an allergic predisposition, pruritus, erythema, 
oozing, crusting, excoriations, lichenification, sensitivity to allergens/irritants, and a 
susceptibility to secondary infections [2, 3]. 
Reactive treatment with topical corticosteroids is the classical paradigm of care, but while 
these compounds are effective, they are restricted in long-term use by local and systemic side 
effects. Specifically, the use of topical corticosteroids is associated with potential local and 
systemic side effects including skin atrophy, telangiectasia, dyspigmentation, suppression of 
the hypothalamic-pituitary-adrenal axis and the rebound effect. Aside from corticosteroids, 
there is only a limited armament of topical treatments available for AD, most of which have 
certain side effects that limit their use.  
Ascomycin derivatives, such as pimecrolimus, represent a class of anti-inflammatory 
macrolactams that inhibit the phosphatase calcineurin [4-6]. Studies on the effect of 
ascomycin derivatives and other immunophilin ligands in animal models of skin 
inflammation provided evidence that they are effective in the treatment of skin diseases in 
humans such as chronic plaque psoriasis, without the well-known side effects of topical 
corticosteroids [7, 8]. Intensive studies on structure-activity relationships and comparative 
pharmacological evaluations resulted in the discovery and development of pimecrolimus [9, 
10]. Pimecrolimus selectively acts on cells involved in skin inflammation, targeting T cells 
and mast cells, and inhibiting the production and release of proinflammatory cytokines. 
ELIDEL® (pimecrolimus) Cream, 1% was approved by the Food and Drug Administration 
(FDA) in 2001 as second-line therapy for the short-term and noncontinuous chronic 
treatment of mild to moderate AD in nonimmunocompromized adults and children 2 years of 
age and older who fail to respond adequately to, or are advised against using, other topical 
prescription treatments. ELIDEL Cream is an innovative therapeutic agent with a mode of 
action different from topical corticosteroids; the product is generally safe and has been 
shown to be effective in the treatment of AD. 
In order to improve patient satisfaction with use, the sponsor is developing a new formulation 
of pimecrolimus. This formulation will include the same concentration of the active 
ingredient as ELIDEL Cream (pimecrolimus 1%), but in a lotion form. It is expected that the 
safety profile of this new formulation, IDP-124 Lotion, will be similar to that of ELIDEL 
Cream. Additionally, the sponsor proposes to evaluate IDP-124 Lotion in patients with

moderate to severe AD in order to establish the safety and efficacy of the product for use in 
patients for whom there is no approved alternative. In this way, IDP-124 Lotion will enhance 
and extend the available therapeutic options for patients with AD. 
The current clinical study is designed to evaluate the efficacy, safety, and tolerability of 
IDP-124 Lotion for the treatment of moderate to severe AD in pediatric and adult subjects.  
 Study Objectives and Purpose 
The objectives of this study are to evaluate the efficacy, safety, and tolerability of IDP-124 
Lotion for the treatment of moderate to severe AD in pediatric and adult subjects.  
 Investigational Plan 
7.1 
Investigators and Study Administrative Structure 
Approximately 20 investigational centers are planned to participate in this study. Each 
clinical investigator will be required to provide a copy of his/her curriculum vitae and 
medical license, complete a financial disclosure statement, and generate a list of study 
personnel who will be involved in the study, with a summary of their roles and qualifications. 
7.2 
Summary of Study Design 
This is a multicenter, randomized, double-blind, parallel group, vehicle-controlled study to 
evaluate treatment success using a 5-point Investigator Global Assessment (IGA) scale from 
clear to severe; the Eczema Area Severity Index (EASI); improvement in total affected body 
surface area (TBSA); assessment of pruritus (itching) and sleep disturbance; Patient-Oriented 
Eczema Measure (POEM)  from subjects and parents/legal guardians of pediatric subjects, 
and investigator’s assessment for presence or absence of signs and symptoms of AD. 
Approximately 348 subjects, ages 2 and older, are planned for randomization (232 subjects to 
IDP-124 Lotion and 116 subjects to IDP-124 Vehicle Lotion). The study consists of a 6-week 
double-blind treatment period and 4-week, post-treatment follow-up. Study visits include 
Screening, Baseline, and Weeks 1, 2, 4, 6, and 10 (subjects will return to the clinic at 
Week 10 for a post-treatment follow-up visit).  
At the Screening Visit, subjects or their parents/legal guardians (when applicable) will sign 
an informed consent/assent form, provide their medical histories, report their previous and 
concomitant medications, and be evaluated against the inclusion/exclusion criteria. Pre-
menses females (ages 9 and older) and all females of childbearing potential will have urine 
pregnancy tests performed. An abbreviated physical examination will be performed, vital 
signs measured (sitting blood pressure, respiration, pulse, and temperature), and blood and 
urine specimens will be collected for serum chemistry, hematology, urinalysis evaluations

and serum pregnancy for pre-menses females (9 and older) and FOCBP. During this visit, the 
investigator will perform the IGA, evaluate the subject for TBSA affected by AD, and for the 
other signs and symptoms of AD.  
At the Baseline Visit, prior to being evaluated by the investigator and study staff, subjects or 
parents/legal guardians (if applicable) are to complete the POEM. At this visit, medical 
histories and concomitant medication use will be updated, and the inclusion/exclusion criteria 
will be confirmed. Adverse events since the Screening Visit will be assessed, and all pre-
menses females (9 and older) and FOCBP will have urine pregnancy tests performed. During 
the Baseline Visit, the IGA, EASI, pruritus and sleep disturbance, and subject's assessment of 
AD will be completed, and the investigator will assess TBSA affected by AD and evaluate 
the subject for other signs and symptoms of AD. 
After confirming eligibility at the Baseline Visit, subjects will be randomized in a 2:1 ratio to 
receive either IDP-124 Lotion or IDP-124 Vehicle Lotion. Subjects or parents/legal 
guardians of pediatric subjects will apply the first dose of the assigned study drug to the 
affected areas of the skin at the investigational center under the supervision of designated 
study personnel. Subjects will receive the study drug and given verbal and written 
instructions for treatment application. Specifically, the subjects will be instructed to apply the 
lotion to the affected areas twice daily, at approximately the same time each day, about 
12 hours apart. The subjects will also receive diaries, with instructions to complete a record 
of all applications (of study drug and bland emollient use) and to note any missed 
applications of the study drug. 
Throughout the study, safety will be assessed by reviewing the occurrence of adverse events 
(AEs), assessing vital sign measurements and abbreviated physical examination findings 
(conducted at Baseline and Week 6), and noting any additions or changes in concomitant 
medication/therapies uses. Blood and urine samples will be collected at Screening and Week 
6 visits for routine safety laboratory evaluations and serum pregnancy testing, as applicable, 
and urine pregnancy tests will be obtained for all pre-menses females (9 and older) and 
FOCBP at each study visit (except Week 1). Efficacy assessments of the IGA, EASI, Pruritus 
and Sleep Disturbances, TBSA affected by AD, evaluation for signs and symptoms of AD, 
and Subject Assessment, will be performed throughout the study. In addition, the POEM 
(Appendix 17.3) will be completed by the subjects/parents/legal guardians at Baseline, Week 
6 and Week 10.  
Additionally, at selected sites, standardized photography will be performed on subjects who 
provide photographic consent, at Baseline, Weeks 2, 4, 6, and 10.  
The study design and schedule of assessments is presented in Table 1.

 Selection and Withdrawal of Subjects 
8.1 
Subject Inclusion Criteria 
Subjects meeting all of the following criteria will be eligible for study entry: 
1. Male or female at least 2 years of age and older.  
2. Written and verbal informed consent must be obtained; subjects less than age of 
consent must sign an assent (as required per IRB/IEC guidelines) for the study and 
a parent or a legal guardian must sign the informed consent (if subject reaches age 
of consent during the study they should be re-consented at the next study visit). 
3. Nonimmunocompromized male or female who failed to respond adequately to 
other topical prescription treatment for AD or for whom those treatments are not 
advisable. 
4. Clear diagnosis of AD fulfilling the diagnostic criteria of Hanifin and Rajka13 that 
affects ≥ 5% of TBSA (see Appendix 17.4 for full list of diagnostic criteria to 
reference); subject should have had a diagnosis of AD for at least 3 months; i.e., 
determined by subject-reported or parent-reported duration of subject experiencing 
itchy and dry skin for 3 months or longer (at Screening and Baseline visits). 
5. Subject must have a score of 3 (moderate) or 4 (severe) on the IGA scale at the 
Screening and Baseline visits. 
6. Subjects must be willing to comply with study instructions and return to the clinic 
for required visits; subjects under the age of consent must be accompanied by the 
parent or legal guardian at the time of assent/consent signing. 
8.2 
Subject Exclusion Criteria 
Subjects meeting any one of the following criteria will be excluded from the study: 
1. Females who are pregnant, breast feeding, or who wish to become pregnant during 
the study period. Women of childbearing potential1 and females that are pre-
menses (9 and older) must be willing to practice effective contraception for the 
duration of the study2. (Effective contraception is defined as stabilized on oral 
contraceptive for at least 3 months, IUD, condom with spermicidal, diaphragm 
                                                 
1 Pre-menses females and FOCBP include any female who has not undergone successful surgical sterilization 
(hysterectomy, bilateral tubal ligation or bilateral oophorectomy) or is not postmenopausal (defined as 
amenorrhea > 12 consecutive months; or women on hormone replacement therapy with documented plasma 
follicle-stimulating hormone level > 35mLU/mL). Even women who are using oral, implanted, or injectable 
contraceptive hormones, an intrauterine device, barrier methods (diaphragm, condoms, spermicidal) to prevent

the ET visit. If appropriate, discontinued subjects may be placed on other conventional 
therapy upon request or whenever clinically necessary, as determined by the physician. The 
End of Study source documents and all relevant data should be entered into the electronic 
case report form (eCRF) system at the time the subject discontinues from the study.  
Reasons for subject withdrawal may include, but are not limited to, the following: 
 Progression of AD, as determined by the investigator, which requires treatment 
with a prohibited therapy 
 At the investigator's discretion for safety reasons (e.g., severe adverse reactions or 
unauthorized concomitant therapy) 
 Subject withdrawal 
 When the requirements of the protocol are not followed 
 When a concomitant therapy likely to interfere with the results of the study is 
reported or required by the subject (the investigator will report all such 
information on the source documents/eCRFs and decide, in accordance with the 
sponsor, whether the subject is to be withdrawn) 
 When a subject is lost to follow-up; the investigator (or designee) will try twice to 
reach the subject by telephone, email and/or text message, and will send a follow-
up letter by certified mail before considering the subject as lost to follow-up. 
These actions will be documented on the End of Study source documents, and a 
copy of the follow-up letter maintained in the investigator's file 
 If a subject becomes pregnant during the treatment period, the study drug will be 
discontinued immediately, the subject will be discontinued from the study, and 
the investigator will notify the sponsor. The pregnancy will be followed to term 
with the outcome reported to the sponsor. 
 Treatment Plan 
9.1 Methods of Assigning Subjects to Treatment Groups 
Eligible subjects will be randomized to receive one of the two study products in a ratio of 2:1 
(IDP-124 Lotion : Vehicle Lotion). The study center will assign each screened subject a 
unique 6-digit study number. The number will consist of the 3-digit study center number 
(pre-assigned by Sponsor/designee) and the 3-digit chronological screening number, starting 
with 001 (e.g., 101001, 101002). The IRT system will assign the study drug kit to subjects 
based on a randomization code at Baseline. One kit will be dispensed to the subjects at 


Protocol V01-124A-301 
 
Valeant Pharmaceuticals North America 
 
Version 5.0 (Amendment #4), 25NOV2019 
 
CONFIDENTIAL 
 
28 
 
Baseline, and Weeks 2, and 4 after accessing IRT, at each visit for kit number assignment, by 
the designated study center staff. For subjects who require more than one kit of study drug, 
an option of an unscheduled visit for dispensing study drug at the Week 1 visit will be 
available in addition to the options of dispensing two kits at Weeks 2 and 4.  A study drug 
log will document the inventory, dispensing, and collection of study drug at each study 
center. The assigned investigational product is to be applied twice daily beginning on Day 1 
for 6 weeks.  
9.2 Randomization and Blinding 
All eligible subjects will be assigned to treatment groups in accordance with a 
computer-generated randomization schedule prepared by the sponsor’s statistical 
programming group. Approximately 348 subjects are planned for enrollment in a 2:1 ratio in 
the 2 treatment groups (IDP-124 Lotion or Vehicle Lotion).  
This is a double-blinded study in which IDP-124 Lotion or Vehicle Lotion will be packaged 
and labeled identically. This level of blinding will be maintained throughout the conduct of 
the study. As a double-blinded study, the investigators, the staff at each investigational 
center, the sponsor, the clinical monitors, and the subjects will be unaware of the assigned 
treatment given to each subject. Designated staff at each investigational center will dispense 
and collect the investigational products as appropriate to minimize inadvertent unblinding. 
The treatment assignments for all randomized subjects will be unblinded only after the 
conclusion of the study. Specifically, the blind will be broken only after: all data are verified, 
entered into the database, and validated; subject evaluability assessments are performed and 
entered into the database; and the database is locked. 
In case of a medical emergency, the investigator can contact the medical monitor and sponsor 
(or sponsor designee) to obtain the treatment assignment for an individual subject. The 
sponsor is to be informed if the randomization code is broken, along with the reasons for 
unblinding. 
9.3 Treatment Compliance 
Subjects and/or their parents/legal guardians will be dispensed one kit (containing 2 tubes) of 
study drug at the Day 1 (Baseline), Week 2, and Week 4 study visits (see Section 9.1 for IRT 
dispensing at these visits). Using a calibrated scale, designated study personnel will weigh 
and record each tube of study drug within the kit, separately (with cap on) to the nearest tenth 
of a gram, before dispensing both tubes to the subject and/or their parent/legal guardian. 
Subjects will be instructed to return their dispensed study drug tubes at the subsequent visits, 
and weights will be collected. Used, partially used, and unused study drug tubes will be

collected and recorded. Tube weights will be recorded in the individual study drug log and in 
the appropriate eCRF.  
Subjects will also receive diaries, with instructions to complete a record of all applications of 
study drug and bland emollients, if applicable (Section 10.1.3), and to note any missed 
applications of the study drug. The study drug application will be in accordance with the 
body diagram marked with the AD lesions that will be provided to the subjects at the 
Baseline visit (note: any new lesions as identified by the subject in between study visits 
should be recorded on the body diagram and treated). Subjects will be instructed to return 
their completed diary at each visit. Note: a  new subject diary will be dispensed at the Week 
6 visit, specifically for the off drug period, and will require recording of bland emollient use 
only; and this diary will be collected at the Week 10 visit. At the Week 1, 2, 4, and 6 study 
visits, designated study personnel will collect and review the completed diaries for treatment 
compliance. Any missed doses of study drug should include an explanation for each missed 
dose. A subject who has deviated from the twice daily dosing regimen will be counseled.  
The dates of missed study drug application will be recorded in the appropriate eCRF. 
9.4 Concomitant Medications / Therapies 
Concomitant medications / therapies refer to all medications / therapies used by the subject 
during the study. During the course of the study, if appropriate, every attempt should be 
made to keep the dosing and regimen of concomitant medications / therapies constant, and 
any change to a medication / therapy during the study must be recorded. Information on 
concomitant medications / therapies (including indication, dosing, and start and stop dates) 
will be recorded in the source document and on the appropriate eCRF. All concomitant 
medications / therapies used during the study will be recorded under Concomitant 
Medications / Therapies source documents and eCRF. 
Disease-related (atopic dermatitis) prior medications / therapies (used within 2 years prior to 
Screening) will be collected/recorded in the eCRF (e.g., Eucrisa, topical corticosteroids, 
biologics, etc). 
All other prior medications / therapies (those used and stopped within 30 days prior to 
Screening) will be recorded under Prior Medications / Therapies in the eCRF (e.g., aspirin, 
acetaminophen, birth control pills, vitamins, herbal products, homeopathic preparations). 
Concomitant medications / therapies (prescription or over-the-counter) that are considered 
necessary for the subject’s welfare and do not interfere with study assessments and 
evaluations will be allowed during the study at the investigator’s discretion.

9.4.2 Permitted Medications / Therapies 
Non-medicated topical products, such as sunscreen and bland emollients are permitted during 
the screening and treatment periods, however, subjects should refrain from using these 
products the morning of the Baseline visit.  
Inhalation steroids and inhaled/systemic antihistamines are permitted provided subjects are 
on a stable dose for at least 2 weeks prior to the baseline visit.  
Opioids are permitted provided subjects are on a stable dose and are not willing to change the 
dose during the course of the study. Unstable dosing or if a subject starts using opioids 
during the study is not permitted.  
Topical or oral antifungals may be used if antifungal treatment is indicated. Topical or oral 
antiviral therapy also is permitted as required.  
9.5 Protocol Deviations and Violations 
A deviation from the protocol is an unintended and/or unanticipated departure from the 
procedures and/or processes approved by the sponsor and the institutional review board 
(IRB)/IEC and agreed to by the investigator. Deviations usually have an impact on individual 
patients or a small group of patients and do not involve inclusion/exclusion or primary 
endpoint criteria.  
A protocol violation occurs when there is nonadherence to the protocol that results in a 
significant, additional risk to the subject, when the subject or investigator has failed to adhere 
to significant protocol requirements (inclusion/exclusion criteria) and the subject was 
enrolled without prior sponsor approval, or when there is nonadherence to United States FDA 
regulations and/or International Conference on Harmonisation (ICH) Good Clinical Practice 
(GCP) guideline. 
The investigator or designee must document and explain in the patients’ source 
documentation any deviations from the approved protocol. The investigator may implement a 
deviation from, or a change of, the protocol to eliminate an immediate hazard to study 
subjects without prior IRB/IEC approval. As soon as possible after such an occurrence, the 
implemented deviation or change, the reasons for it, and any proposed protocol

amendment(s) should be submitted to the IRB/IEC for review and approval, to the sponsor 
for agreement, and to the regulatory authorities, if required. 
 Study Drug Materials and Management 
The study drug will be provided to the investigational centers by the sponsor (or sponsor 
designee) and will be dispensed to the subject and their parent/legal guardian (as required) by 
the pharmacy or an appropriately qualified member of the study staff assigned by the 
investigator. 
All laboratory kits containing materials necessary to collect blood and urine for routine 
clinical laboratory tests and urine for pregnancy testing will be supplied to the clinical centers 
by the designated central laboratory.

10.1.3 Treatment Administration 
Subjects and their parents/legal guardians will receive both verbal and written instructions 
(Appendix 17.1) on the application of the study drug. Study drug will be applied as a thin 
layer to the affected areas of the skin, twice daily at approximately the same time each day 
and about 12 hours apart. The subject and/or their parent/legal guardian will apply the first 
dose of study drug at the investigational center during the Baseline Visit under the 
supervision of designated study personnel. On subsequent study visit days, subjects will 
apply one dose of study drug at the investigational center, depending on time of study visit 
(subjects should not apply study drug prior to coming in to the center for their study visit if 
the scheduled visit is in the morning). All of the remaining study drug doses will be applied 
at home. Study drug will continue to be applied for the duration of the 6-week treatment 
period, even if complete clearing of the affected areas has been observed; i.e., all originally 
identified lesions will continue to be treated even if cleared (refer to Appendix 17.1).  
New areas of the skin that become affected during the study may be treated with study drug. 
The subject or parent/legal guardian may begin study drug application to new lesion/s 
without the investigator’s confirmation. They must record new lesions on the same body 
diagram provided and in the study diary, and inform the investigator of new lesion treatment 
at the next study visit. 
Non-medicated bland emollients, such as CeraVe®, Eucerin®, or Aquaphor®, may be applied 
during the study at the discretion of the subject and/or parent/legal guardian, and investigator. 
Appendix 17.2 provides an example list of allowable non-medicated bland emollients to be 
used during the study. Subjects will be instructed to apply the emollient (if needed) at least 
20-30 minutes after study drug application. If subjects have been using bland emollients 
during the screening period, they will be reminded not to apply emollients the morning of the 
Baseline visit. All emollients used should be captured in the source documents and eCRF.  
Subjects may gently wash (e.g., take a bath or shower) the areas of treatment shortly before 
the application of study drug. Subjects should allow the skin to dry completely before 
application of the study drug. After application, the treated skin should not be washed for at 
least 3 hours. 
10.2 Study Drug Accountability 
The investigator or designee will be responsible for keeping current and accurate records of 
the amount of study drug received and dispensed, and its disposition. The study drug must be 
stored under the appropriate conditions in a secure area and is to be dispensed only to 
subjects enrolled in the study, in accordance with the conditions specified in this protocol.

Valeant Pharmaceuticals North America 
 
Version 5.0 (Amendment #4), 25NOV2019 
 
CONFIDENTIAL 
 
36 
 
During the course of the study, the investigator or designee must maintain an inventory of all 
study drug dispensed to or returned by the subject, including subject identifiers. 
A study drug accountability log will be completed by the investigator or designee to 
document the receipt, dispensation, and return of study drug tubes.  
At the end of the study, the sponsor will provide instructions as to disposition of any 
remaining used and unused study drug tubes, and any other ancillary supplies.  
 Study Procedures and Evaluations 
11.1 Schedule of Evaluations and Procedures 
All subject information and data obtained during the study visit procedures must be recorded 
in the source documents, applicable study logs, and eCRFs. 
11.1.1 Screening Visit (Visit 1, Day −35 to 0) 
After signing the informed consent/assent, subjects will undergo the screening procedures to 
confirm eligibility to participate in the study. 
The following procedures will be conducted at this visit: 
1. Review and explain the nature of the study. Provide a visit schedule with the 
length of each visit to ensure that the subject can meet the requirements and has 
adequate transportation. 
2. Obtain verbal and written informed consent/assent from the subject and the 
subject’s parent or legal guardian prior to performing any study-related procedures. 
Provide signed copies of the consent and assent forms to the subject/parent or legal 
guardian. 
3. Assign a 6-digit study number by accessing IRT which includes the 3-digit 
investigational center number plus a unique 3-digit subject number beginning with 
001 (e.g., 101001, 101002, 101003, etc.; in this example site number is 101).  
4. Record subject’s demographic information (sex, date of birth, age, ethnicity, and 
race). 
5. Record subject’s medical history. 
6. Collect a detailed history of AD, including an estimated start date, duration, and all 
previous medications/therapies used for AD treatment within the last 2 years. 
7. Review all prior medications (those used within 30 days prior to the Screening 
Visit) and previous medications used by the subject.  
8. Review inclusion/exclusion criteria.

9. Perform a urine pregnancy test3 for all females who are pre-menses (9 and older) 
and female subjects of childbearing potential.4 Exclude the subject if the 
pregnancy test result is positive.  
Urine pregnancy testing is mandatory for all female subjects who are pre-
menses (9 and older) and females of childbearing potential at Screening, 
Baseline, and at the Week 2, 4, 6 and 10 study visits. The decision may be 
made by the investigator to do additional urine pregnancy tests during the 
course of the study. 
10. Obtain vital sign measurements. Vital signs will be measured after the subject is 
seated for at least 5 minutes, and will include systolic and diastolic blood pressure, 
pulse rate, respiratory rate, and oral body temperature (for younger pediatric 
subjects, aural or temporal temperatures will be allowed provided the same method 
is used for all study visits). 
11. Measure height and weight. 
12. Conduct an abbreviated physical examination (excluding urogenital/reproductive 
systems).  
13. Perform an evaluation of the subject’s TBSA affected by AD (using diagnostic 
criteria in Appendix 17.4). 
14. Perform an IGA. 
15. Collect blood and urine samples for routine safety laboratory analysis 
(hematology, serum chemistry, urinalysis, and serum pregnancy testing for pre-
menses females [9 and older] and FOCBP).5 Process and ship the samples to the 
central safety laboratory per instructions provided in the laboratory manual. 
16. If eligible to return for the Baseline visit, if applicable, remind the subject to 
refrain from using nonmedicated topical products (e.g.(e.g., sunscreens, lotions, 
creams, bland emollients) the morning of the Baseline visit.  
17. Schedule subject to return for the Baseline Visit (Visit 2, Day 1). 
If a subject fails screening, either at the Screening or Baseline visit (prior to 
first dose of study drug), the subject may be rescreened at a later date. 
                                                 
3 Urine pregnancy tests must have a minimum sensitivity of 25 mIU of human chorionic gonadotropin per mL 
of urine. Urine pregnancy test kits will be provided by the sponsor. 
4 Premenses females and FOCBP include any female who has not undergone successful surgical sterilization 
(hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or is not postmenopausal (defined as 
amenorrhea for > 12 consecutive months or women on hormone replacement therapy with documented plasma 
follicle-stimulating hormone levels > 35 mIU/mL). Even women who are using oral, implanted, or injectable  
contraceptive hormones, an intrauterine device, barrier methods (diaphragm, condoms, spermicidal) to prevent 
pregnancy, practicing abstinence, or where partner is sterile (e.g., vasectomy) should be considered to be of 
childbearing potential. 
5 Refer to Appendix 17.5 for a list of analytes that will be analyzed for the blood and urine sample collections.

guardian to complete the appropriate POEM. 
2. Record any AEs (query subjects and their parents/legal guardians, “Are there any 
changes in your health since the last visit?”). 
3. Review the safety laboratory test results.  
If any safety laboratory test results obtained at the Screening Visit, which will 
be received by the investigator prior to conducting the Baseline Visit, are 
abnormal and clinically significant as determined by the investigator, the 
investigator should discuss with the medical monitor whether it is in the 
subject’s best interest to participate in the study prior to enrolling.

13. Exit the subject from the study and complete the end of study eCRFs. 
11.1.5 Unscheduled Visits 
Additional visits may be scheduled, as necessary, to ensure the safety and wellbeing of 
subjects. All additional examinations should be fully documented in the source documents 
and on Unscheduled Visit eCRFs, as appropriate. Visits intended to fulfill scheduled visit 
requirements that fall outside the designated scheduled visit range, are not unscheduled visits. 
In these cases, the visit data will be collected and transcribed to the appropriate scheduled 
visit eCRF.  
11.2 Evaluation of Efficacy 
11.2.1 Total Body Surface Area (TBSA) 
The investigator will assess the percent of TBSA (≥5% required to qualify at Screening and 
Baseline) affected by AD in the allowed treatment areas for each subject at 
Screening/Baseline and at all study visits.  The percent of TBSA will be assessed by utilizing 
the handprint (palm including all the digits) method.

42 
 
When utilizing the handprint (palm including all the digits) method to asses a subject’s 
TBSA estimation, the outstretched hand (including all five digits adducted together) equals 
approximately 1% of the subject’s TBSA.  NOTE:  The subject’s hand is the hand of 
reference and not the assessor’s hand. 
11.2.2 Investigators Global Assessment  
At Screening, Day 1 (Baseline), Week 1, 2, 4, 6 and 10 study visits (all visits), AD severity 
will be determined by the investigator/evaluator based on a global assessment of the 
inflammatory signs of AD. Evaluations will be graded on a static scale ranging from 0 (clear) 
to 4 (severe) as shown in the following table: 
Score 
Grade 
Description 
0 
Clear 
No inflammatory signs of AD (no erythema, no induration/papulation, no 
lichenification, no oozing/crusting). Post-inflammatory hyperpigmentation 
and/or hypopigmentation may be present. 
1 
Almost clear 
Barely perceptible erythema, barely perceptible induration/papulation, and/or 
minimal lichenification. No oozing or crusting.  
2 
Mild 
Slight but definite erythema (pink), slight but definite induration/papulation, 
and/or slight but definite lichenification. No oozing or crusting. 
3 
Moderate 
Clearly perceptible erythema (dull red), clearly perceptible 
induration/papulation, and/or clearly perceptible lichenification. Oozing and 
crusting may be present. 
4 
Severe 
Marked erythema (deep or bright red), marked induration/papulation, and/or 
marked lichenification. Disease is wide-spread in extent. Oozing or crusting 
may be present.  
 
The primary efficacy variable is the IGA score at Week 6. Treatment success is defined as 
achieving clear to almost clear (i.e., a score of 0 or 1) and at least a 2-grade improvement in 
the IGA score at the end of treatment compared with Baseline.  
11.2.3 Eczema Area Severity Index (EASI) 
At Day 1 (Baseline), and Weeks 1, 2, 4, 6, and 10,  the EASI will be calculated. The EASI is 
defined as a composite score based on the evaluated severity of 4 key signs of AD 
(i.e., erythema, infiltration/papulation, excoriation and lichenification), and the extent of 
disease in each of the 4 body regions (i.e., head/neck, trunk, upper limbs, and lower limbs). 
The area of involvement (affected by inflammation, not including dry skin) of each of the 
4 body regions will be determined and represented by a numeric coded value based on a scale 
from 0 to 6 as described below (the investigator is required to record the affected TBSA on 
the eCRF).

At Day 1 (Baseline), Week 6 (end of treatment) and Week 10 (end of study), adult subjects 
and parents/legal guardians of pediatric subjects will complete the POEM questionnaire (see 
Appendix 17.3). The POEM questionnaire is a self-assessment of atopic eczema symptoms 
for adult subjects and for parents/legal guardians of children (11, 12). The POEM for Self-
Assessment questionnaire should be completed by subjects ≥8 years of age, and the POEM 
for Proxy Completion should be completed by parents/legal guardians of pediatric subjects 
less than 8 years of age. 
11.2.8 Photography 
At select sites, photographs will be taken at Baseline, and at Weeks 2, 4, 6 and 10. Only 
subjects who provide written photographic consent for photographs will be included in 
photography. Reference shall be made to the photographic manual for this study. 
11.3 Evaluation of Safety 
11.3.1 Clinical Laboratory Tests 
Blood and urine samples will be collected for routine safety laboratory tests (hematology, 
serum chemistry, and urinalysis) at Screening and Week 6 (or ET). Any subject with a 
screening laboratory abnormality that is determined by the investigator to be clinically 
significant must be approved for inclusion in the study by the medical monitor. All results 
will be reported, including abnormal results. Clinically significant changes in lab results from 
Screening, in the opinion of the investigator, should be reported as AEs. Clinically significant 
changes present at Week 6 (or ET) are to be followed to resolution or until clinically stable as 
determined by the investigator. If an AE should require laboratory testing, the results of the 
test must be obtained by the investigational center and filed in the subject’s documentation. 
Materials for sample collection will be provided to the investigational centers by the sponsor 
or central laboratory. Instructions for processing and shipping samples to the central 
laboratory are contained in the study-specific laboratory manual.

For all female subjects who are pre-menses (9 and older) and females of childbearing 
potential, a serum pregnancy test will be conducted at Screening and Week 6 (or ET). 
Additionally, urine pregnancy testing will be performed at all study visits (except Week 1). 
The results at the Screening and Baseline visits must be negative for a subject to enter the 
study. Materials for pregnancy testing will be provided to the investigational centers by the 
sponsor, CRO or central laboratory. 
11.3.2 Vital Sign Measurements 
Measurement of vital signs will be performed at Screening and Week 6 (or ET). After the 
subjects have been sitting for at least 5 minutes, systolic and diastolic blood pressures, pulse 
rates, respiration rates, and oral temperatures will be recorded (for younger pediatric subjects, 
aural or temporal temperatures will be allowed provided the same method is used across all 
study visits). 
11.3.3 Physical Examinations 
An abbreviated physical examination will be performed at Screening and Week 6 (or ET). 
Height and weight will be measured at both visits.  
11.3.4 Adverse Events 
An AE is any untoward medical occurrence in a subject or clinical investigation subject 
administered a medicinal product and which does not necessarily have a causal relationship 
with the study drug. Thus, AEs include any unfavorable and unintended illness, sign, 
symptom, clinically significant laboratory test abnormality, or disease temporally associated 
with the use of a medicinal product that has appeared or worsened during the course of the 
clinical study, regardless of causal relationship to the study drug(s) under study. The 
collection of non-serious AEs and serious AEs (SAEs) should begin following the subject’s 
completion of the consent/assent process to participate in the study. 
Descriptions of AEs will include the dates of onset and resolution, maximum severity, 
seriousness, action taken regarding study drug, corrective treatment, outcome, and 
investigator’s assessment of causality. Worsening of disease will not be considered an AE 
unless it results in discontinuation of the subject from the study or requires medical 
intervention prohibited by the protocol. All AEs will be followed to resolution or until stable 
as determined by the investigator. 
11.3.4.1 Serious Adverse Events 
All AEs will be assessed as either serious or non-serious. An SAE or serious adverse reaction 
is defined as any untoward medical occurrence that at any dose: 
 Results in death 


Protocol V01-124A-301 
 
Valeant Pharmaceuticals North America 
 
Version 5.0 (Amendment #4), 25NOV2019 
 
CONFIDENTIAL 
 
48 
 
 Is immediately life-threatening, (the term “life-threatening” in the definition of 
“serious” refers to an event in which the subject is at risk of death at the time of 
the event; it does not refer to an event which hypothetically might have caused 
death if it were more severe) 
 Requires in subject hospitalization or prolongation of existing hospitalization 
(hospitalization for elective surgery for a baseline condition is not considered an 
AE) 
 Results in persistent or significant disability/incapacity (permanent or substantial 
disruption of a person’s ability to conduct normal life functions) 
 Is a congenital anomaly/birth defect 
 Is a medically important event that may not be immediately life-threatening or 
result in death or hospitalization, but may jeopardize the subject and may require 
medical or surgical intervention to prevent one of the above listed outcomes 
Important medical events that may not have resulted in death, be life-threatening, or require 
hospitalization may be considered an SAE when, based upon appropriate medical judgment, 
they may jeopardize the subject and may require medical or surgical intervention to prevent 
one of the outcomes listed in this definition. Examples of such medical events include 
allergic bronchospasm requiring intensive treatment in an emergency room or at home, blood 
dyscrasias, or convulsions that do not result in inpatient hospitalization, or the development 
of drug dependency or drug abuse. 
Hospitalization is a criterion for assessment of seriousness. To qualify as serious under the 
criteria of “hospitalization,” a hospital admission of at least a 24-hour period is required. If a 
subject is retained the emergency room greater than 24 hours, but not admitted for medical 
care, these cases should be evaluated individually, as criteria such as “medically significant” 
may also apply.  
Hospitalization without a medical AE should not be considered either serious or an AE. 
Examples include the following: 
 Admission for treatment of a pre-existing condition not associated with the 
development of a new AE or with worsening of the pre-existing condition (e.g., 
for work-up of persistent pretreatment lab abnormality) 
 Hospitalization for a purpose unrelated to the study (e.g.,, “planned” or elective 
surgery scheduled prior to study participation) would not ordinarily need to be 
reported, unless a complication occurred which otherwise caused prolongation of 
this hospitalization

 Protocol-specified admission or procedure (e.g., cataract surgery required by a 
study protocol; or overnight stay for monitoring due to protocol required surgery, 
with no associated SAE or complication necessitating prolonged stay) 
 Social admission (e.g., social hospitalization for purposes of respite care) 
Note: A spontaneous abortion and elective abortion will be considered as SAEs, and must be 
reported to the sponsor within 24 hours of your awareness of the event. 
11.3.4.2 Assessment of Severity and Causality of Adverse Events 
The severity assigned to an AE should be determined by the maximum severity of the AE. 
The categories described below should be used to estimate the severity of AEs: 
 Mild:  Awareness of a sign or symptom but is easily tolerated, requires no 
treatment and does not interfere with subject’s daily activities.  
 Moderate:  Low level of concern to the subject and may interfere with daily 
activities, but can be relieved by simple therapeutic care.  
 Severe:  Interrupts the subject’s daily activity and requires systemic therapy or 
other treatment.  
The investigator should assess the relationship of the AE, if any, to the study drug as either 
“Related” or “Not Related.”  
 Related: There is at least a reasonable possibility that the AE/SAE is related to 
the study drug. Reasonable possibility means that there is evidence to suggest a 
causal relationship between the drug and the AE. 
 Not Related: There is little or no reasonable possibility that the AE/SAE is 
related to the study drug. This assessment implies that the AE/SAE has little or no 
temporal relationship to the study drug and/or a more likely or certain alternative 
etiology exists. 
The following should be taken into account when assessing AE/SAE causality: 
 Positive temporal relationship to study drug, such as if the study drug was 
withdrawn and the SAE resolved or the event recurred after re introduction 
 If there is a reasonable possibility that the AE is associated with an underlying or 
concomitant illness 
 Possible association with previous or concomitant therapy

 No temporal relationship to the study drug and/or a more likely alternative 
etiology exists 
 If the AE is directly related to study procedures or there is a lack of efficacy 
11.3.4.3 Procedures for Reporting Adverse Events and Serious Adverse Events 
Throughout the course of the study, efforts will be made by the investigator to remain alert to 
possible AEs that are either systemic or ocular in nature. The period of observation for 
collection of AEs extends from the time the subject and parent/legal guardian gives informed 
consent/assent until the last study visit or discontinuation from the study. The first concern 
will be the safety of the subject, and appropriate medical intervention will be made.  
The investigator or designee will elicit reports (i.e., via direct questioning, observation, 
clinical evaluation) of AEs from the subject at each study visit and record all AEs. The 
investigator will document the dates of onset, progress, outcome, and resolution of such AEs. 
The investigator will also provide an assessment of all AEs as to the severity, causal 
relationship to study drug, and causal relationship to study protocol.  
It is the investigator’s responsibility to document all AEs that occur during the study. The 
AEs should be documented as a single medical diagnosis. When this is not possible, the AE 
should be documented in terms of signs and/or symptoms observed by the investigator or 
reported by the subject and/or their parent/legal guardian at each study visit.  
All AEs occurring after the subject and their parent/legal guardian signs the assent/informed 
consent through the last study visit must be reported, regardless of whether or not the AEs 
are considered drug-related. All AEs, whether in response to a query, observed by the clinical 
center personnel, or reported spontaneously by the subject and/or their parent/legal guardian, 
will be recorded. 
At each visit during the study, the subject will be assessed for the occurrence of new and 
ongoing AEs. Cutaneous tolerability signs and symptoms that result in the subject’s requiring 
a concomitant therapy or discontinuation from the study will be reported as an AE. The 
following data will be collected on all AEs and recorded on the appropriate eCRF: 
 Event name (diagnosis preferred, if unknown, record the signs/symptoms) 
 Onset date and end date 
 Maximum intensity (severity) 
 Seriousness 
 Action taken regarding study drug

Valeant Pharmaceuticals North America 
 
Version 5.0 (Amendment #4), 25NOV2019

51 
 
 Corrective treatment, if given 
 Outcome 
In addition, the investigator’s assessment of causality will be recorded. 
Any SAE must be reported to the sponsor, independent of the circumstance or suspected 
cause, within 24 hours from the time the event was reported to the investigator. All SAEs 
experienced from the date of consent through at least 30 days after the last dose of study drug 
must be reported to the sponsor regardless of the relationship to the study drug or the 
protocol. For events occurring beyond the minimum 30-day period after the last dose of 
study drug, or for any timeframe afterward deemed medically significant, only SAEs 
considered related to the study drug should be reported promptly to the sponsor. 
Within 24 hours of notification the investigator will fax or email a completed Serious 
Adverse Event Report to the following:  
Investigators should not wait to receive additional information to document the event before 
notifying the sponsor of an SAE. If only limited information is initially available, follow-up 
reports are required. If the investigator becomes aware of any new information regarding a 
SAE (ie, resolution, change in condition, or new treatment), a new SAE Form must be 
completed and faxed/emailed to the sponsor within 24 hours. The original SAE Form is not 
to be altered. The report should be marked as a “follow-up report” and describe whether the 
event has resolved or continues and how the event was treated. Additional relevant 
information such as hospital records and autopsy reports should be provided to the sponsor as 
soon as they are available.  
Should the investigator become aware of an SAE (regardless of its relationship to 
investigational product) that occurs within 30 days after stopping the study drug, the SAE 
must be reported in accordance with procedures specified in this protocol.

Valeant Pharmaceuticals North America 
 
Version 5.0 (Amendment #4), 25NOV2019

52 
 
The investigator should take all appropriate measures to ensure the safety of the subjects, 
notably he/she should follow a subject with an SAE until the event has resolved or the 
condition has stabilized. This may imply that follow-up will continue after the subject has 
left the study, and that additional investigations may be requested by the sponsor. 
11.3.4.4 
Submitting an Expedited Safety Report to the Institutional Review Board  
Any suspected unexpected serious adverse reaction warrants expedited reporting. In addition, 
any unexpected SAE related to a subject’s participation in the study (or conduct of study), 
regardless if the study drug was administered, will be evaluated by Global Safety and 
Vigilance to determine if expedited reporting is required. For example, an unexpected, 
serious and severe reaction which could be associated to the study procedures, and which 
could modify the study conduct requires expedited reporting. 
Each expedited safety report will routinely include a brief cover memorandum, the 
completed MedWatch Form FDA 3500A or Council for International Organizations of 
Medical Sciences I Form, a clinical analysis of the event with any similar events that have 
occurred with the product, and any additional pertinent information recommended by the 
study medical monitor. Once the report is compiled, the clinical center investigator must 
submit the expedited safety report to the local IRB/IEC within the required reporting 
timeframe. Follow-up reports should be submitted when requested or when pertinent 
information becomes available. The principal investigator must retain a complete copy of 
each expedited safety report as it was submitted to the IRB/IEC. It is important that the 
principal investigator review these expedited reports, as they contain safety information that 
may be relevant to each of the participating subjects. 
11.3.5 Pregnancy 
All pre-menses females (9 and older) and female subjects of childbearing potential must use 
an effective method of birth control during the course of the study, in a manner such that risk 
of contraceptive failure is minimized. Abstinence is allowed as a birth control method. 
Before enrolling a female subject of childbearing potential in this clinical study, the 
investigator must review the following information about study participation: 
 Informed consent/assent requirements. 
 Contraceptives in current use. 
Following review of this information and appropriate counseling for the subject and their 
parent/legal guardian, the investigator or designee and the subject and parent/legal guardian 
must sign the assent/informed consent before study enrollment.

Version 5.0 (Amendment #4), 25NOV2019 
 
CONFIDENTIAL 
 
53 
 
During the study, all pre-menses females (9 and older) and female subjects of childbearing 
potential should be instructed to contact the investigator immediately if they suspect they 
might be pregnant (e.g., missed or late menstrual period). 
If a subject or investigator suspects that the subject may be pregnant prior to study 
enrollment, the study drug must be withheld until the results of laboratory pregnancy testing 
are available. If pregnancy is confirmed, the subject must not receive study drug and must 
not be enrolled in the study. If pregnancy is suspected while the subject is receiving study 
treatment, the study drug must immediately be withheld until the result of pregnancy testing 
is known. If pregnancy is confirmed, the study drug will be permanently discontinued and the 
subject will be followed until the pregnancy comes to term. A Pregnancy Report form will be 
submitted to the sponsor, initially within 24 hours of the investigator’s awareness and at the 
end of the pregnancy, which includes the outcome of the pregnancy and any complications 
occurring during the pregnancy or the delivery. If a pregnancy is associated with an SAE, 
and SAE report form and the pregnancy report form should be submitted to the sponsor 
within 24 hours of the investigators awareness. 
 Statistics 
All statistical processing will be performed using SAS® unless otherwise stated. No interim 
analyses are planned. Except where noted, all statistical tests will be two-sided and will be 
performed at the 0.05 level of significance. 
Descriptive statistics will be used to provide an overview of the efficacy and safety results. 
For categorical parameters, the number and percentage of subjects in each category will be 
presented. For continuous parameters, descriptive statistics will include n (number of 
subjects), mean, standard deviation, median, minimum, and maximum. Appropriate 
inferential statistics will be used for the primary, secondary, and tertiary efficacy variables. 
The primary method of handling missing efficacy data will be the method of Markov Chain 
Monte Carlo (MCMC) multiple imputation. As a sensitivity analysis, the last observation 
carried forward method (LOCF) will be used (i.e., the last available on-therapy observation 
for a subject will be used to estimate subsequent missing data points). Additionally, a tipping 
point analysis will be performed for the primary endpoint. No imputations will be made for 
missing safety data. 
A statistical analysis plan (SAP), describing all statistical analyses will be provided as a 
separate document. The SAP will be finalized prior to unblinding of the study treatments.

for discontinuation will be included. 
12.2 Demographics and Baseline Characteristics 
Subject demographic and baseline characteristics will be summarized by treatment group for 
the intent-to-treat (ITT) population, the Week 6 per protocol (PP) population, and the Week 
10 PP population. For continuous variables (e.g., age) comparisons among the 2 treatment 
groups will be conducted using a 2-way analysis of variance with factors of treatment and 
analysis center. Ethnicity and race will be analyzed with a Cochran-Mantel-Haenszel (CMH) 
test stratified by analysis center. Past and current medical conditions, as well as history of 
disease will not be compared statistically. 
12.3 Protocol Deviations 
All protocol deviations will be reported to the sponsor and recorded throughout the study. A 
data listing of protocol deviations will be included in the final study report. 
12.4 Compliance 
The extent of exposure to study drug in each treatment group will be summarized by total 
number of days of exposure, total number of applications, number of missed applications, 
percentage of expected applications applied and number and percentage of subjects who are 
compliant. A subject will be considered compliant with the dosing regimen if the subject 
applied 80% to 120% of the expected number of applications while enrolled in the study. 
12.5 Efficacy  
The primary efficacy endpoint will be the percent of subjects with treatment success, defined 
as at least a 2-grade improvement from Baseline in IGA score and an IGA score equating to 
clear or almost clear. 
12.5.1 Primary Efficacy 
The primary efficacy endpoint will be used to compare twice daily application of IDP-124 
Lotion and Vehicle Lotion.  
The percentage of subjects with treatment success at Week 6 will be analyzed using CMH 
test stratified by analysis center. 
12.5.2 Secondary Efficacy

 The percentage of subjects with EASI 75 (at least a 75% reduction) at Week 6 where 
the EASI score is defined as a composite score based on the evaluated severity of 4 
key signs of AD (i.e., erythema, infiltration/papulation, excoriation, and 
lichenification), and the extent of disease in each of the 4 body regions (i.e., 
head/neck, trunk, upper limbs, and lower limbs) will be analyzed using the CMH test 
stratified by analysis center. 
 The percentage of subjects with EASI 75 (at least 75% reduction) at Week 4 will be 
analyzed using the CMH test stratified by analysis center. 
 
Dichotomized IGA score at Week 10 where treatment success is defined as achieving 
clear to almost clear (i.e., score of 0 or 1) and at least a 2-grade improvement in the 
IGA from Baseline. These data will be analyzed using the CMH test stratified by 
analysis center. 
 The percentage of subjects with EASI 75 (at least 75% reduction) at Week 10 will be 
analyzed using the CMH test stratified by analysis center.

(i.e., score of 0 or 1) and at least a 2-grade improvement in the IGA from Baseline. 
These data will be analyzed using the CMH test stratified by analysis center. 
Evaluation of the secondary efficacy variables will use a gated sequential procedure starting 
with the comparisons of the first bulleted item and proceeding onto the next item. The 
process will terminate if a nonstatistically significant value is observed. 
12.5.3 Tertiary Efficacy 
The following tertiary efficacy endpoints will be analyzed to further characterize the 
treatment effect of IDP-124 Lotion over the Vehicle Lotion.  
 Percentage of subjects with at least a “2-grade improvement” (based on bandings as

signs and symptoms of AD at Weeks 1, 2, 4, 6 and 10 – Investigators assessment at 
each visit for hyperpigmentation, hypopigmentation, and dry skin. 
 Mean percent change from Baseline in the affected TBSA at each study visit. 
All but the mean percent change from Baseline in the affected TBSA will be analyzed with 
the CMH test stratified by analysis center. The analysis of TBSA will use Analysis of 
Covariance with factors of treatment and analysis center and a covariate of the baseline 
TBSA score. Analyses of tertiary endpoints will be performed without adjusting for 
multiplicity. 
12.5.4 Pooling Analysis 
The clinical study will be conducted under a common protocol for each investigational site 
with the intention of pooling the data for analysis. Every effort will be made to promote 
consistency in study execution at each study site. The study is intended to be conducted in a 
manner such that a minimum of 15 subjects will be randomized and included in the ITT 
population (i.e., approximately at least 10 subjects in the IDP-124 Lotion arm and at least 
5 subjects in the Vehicle Lotion arm) for any investigational site. In the event that there are 
too few subjects in a treatment arm for an investigator, then the investigator’s data will be 
combined to achieve the desired sample size minimum per treatment arm. The combining of 
investigator data will be accomplished, within geographic region, by taking the investigator 
with the smallest enrollment and combining it with the investigator with the largest, restricted 
to investigational sites that did not meet minimum enrollment. If there is a further need to 
combine data, then the data of the investigator with the second smallest enrollment will be 
combined with the investigator's data which had the second largest enrollment, and so on. 
This process will continue for all investigators who did not have a minimum of 15 subjects 
enrolled. The process of combining investigator data that have insufficient subjects per 
treatment arm will result in redefining the groups of investigators for the purposes of 


Protocol V01-124A-301 
 
Valeant Pharmaceuticals North America 
 
Version 5.0 (Amendment #4), 25NOV2019

57 
 
statistical analyses. These combined groups will be referred to as "analysis centers" in the 
statistical analyses. 
The consistency of treatment response will be investigated across the analysis centers 
subsequent to combining the data as described above. Statistical tests will be conducted to 
identify if there are extreme analysis centers that could affect the interpretation of common 
statistical and clinical conclusions. For the purpose of testing consistency of treatment 
response, the primary efficacy variable will be considered. The percent of subjects with 
treatment success at Week 6 will be analyzed with a logistic regression with factors of 
treatment group, analysis center, and the interaction term of treatment group by analysis 
center. Further examination will follow if the analysis results in a significant interaction term. 
In the event that the logistic regression interaction p-value is less than or equal to 0.10, a 
sensitivity analysis that excludes analysis centers with the extreme efficacy result will be 
performed to determine the robustness of the treatment effect. On the other hand, if the 
analysis results in an interaction terms with p-value greater than 0.10, then the conclusions 
from the pooled data will be considered to be free of the impact of extreme analysis centers. 
The first step in conducting a sensitivity analysis is to identify the extreme analysis center or 
centers that contribute to the statistical significance of the interaction term of the logistic 
regression. The process involves submitting subsets of analysis centers to the logistic 
regression and observing the interaction p-value for the subset. Subsets resulting in 
interaction p-values greater than 0.10 are considered homogeneous. 
The search for an extreme analysis center begins by analyzing all subsets that can be created 
by excluding 1 analysis center. If 1 or more of the subsets result in an interaction p-value 
greater than or equal to 0.10, then the analysis center excluded from the subset with the 
largest interaction p-value is deemed the extreme analysis center. 
If all subset interaction p-values are less than or equal to 0.10, then the process will analyze 
the interaction for all subsets that can be created by excluding 2 analysis centers. If 1 or more 
of these subsets generate interaction p-values larger than 0.10, then the analysis centers 
excluded from the subset with the largest interaction p-value are deemed the extreme analysis 
centers. 
Thus, the process of identifying the extreme analysis centers will continue in a stepwise 
manner by first excluding 1, then 2, then 3, etc, analysis centers until the logistic regression 
interaction p-value exceeds 0.10. 
Once the extreme analysis center or centers have been identified, then the treatment p-values 
of the remaining analysis centers will be computed. Inferences will be drawn from the 
treatment p-value, as well as any pertinent observations regarding the extreme analysis center

or centers. Additionally, it is noted that this process excludes subjects from the analysis in a 
nonrandom manner and has an unpredictable impact on the power of the treatment effect test.  
In the event that the treatment effect of the remaining subset is not statistically significant, 
due consideration of the post hoc aspects of the process will be given when the results are 
interpreted. Conclusions will be presented by the sponsor as appropriate to the findings of the 
sensitivity analysis. 
Prior to investigating the treatment effect within the analysis centers, the magnitude of the 
site main effect will be investigated to determine if the main site-to-site variability is such 
that it could mask the analysis center effects. Thus, prior to pooling, the percent of subjects 
with treatment success at Week 6 will be analyzed with a logistic regression with factors of 
treatment group, site, and the interaction term of treatment group by site. If the analysis is not 
computationally feasible due to some sites having very few subjects enrolled, the low 
enrolling sites will be excluded from the analysis. 
12.5.5 Sensitivity Efficacy Analyses 
12.5.5.1 Analyses Using Last Observation Carried Forward 
In the first set of sensitivity analyses, missing IGA values will be imputed using LOCF. 
Treatment success at Week 6 will be analyzed as it was in the primary analyses. Comparisons 
will be performed on imputed data using CMH tests stratified by analysis center. 
12.5.5.2 Repeated Measures Analysis on Observed Data 
As a second sensitivity analysis, treatment success at Week 6 will be analyzed with a 
repeated measures logistic regression model (generalized estimating equations), with 
treatment success as the dependent variable and treatment, analysis center and visit 
(Weeks 1, 2, , 4 and 6) as independent factors. 
12.5.5.3 Tipping Point Analysis 
A tipping point analysis of the primary endpoint will be performed as a sensitivity analysis 
for the handling of missing data. 
12.5.6 Subgroup Analyses 
Subgroup analyses will be conducted for the ITT population for the following subgroups: 
Baseline IGA, sex, age, ethnicity, race, and geographic region. Subgroup analyses will be 
conducted on the primary efficacy endpoint and will contain only descriptive statistics.

12.6 Safety 
12.6.1 Adverse Events 
The primary analysis of safety will be conducted at Week 6. There will be a separate 
tabulation of the AEs that start in the period post Week 6, to Week 10 visit. All AEs 
occurring during the study will be recorded and classified using terminology from the 
Medical Dictionary for Regulatory Activities (MedDRA). All reported treatment-emergent 
adverse events (TEAEs), defined as any AE with an onset on or after the date of first study 
drug application, will be summarized by treatment group and will provide the number of 
subjects reporting TEAEs, system organ class, preferred term, severity, and relationship to 
study drug. When summarizing TEAEs by severity or relationship to study drug, each subject 
will be counted only once within a system organ class or a preferred term using the event 
with the greatest severity or causality, respectively, within each category. All reported SAEs 
will be summarized by the number of subjects reporting the event, system organ class, 
preferred term, severity, and relationship to study drug. 
All information pertaining to AEs noted during the study will be listed by treatment group 
and subject and will include a verbatim description of the event as reported by the 
investigator, as well as the preferred term, system organ class, start date, stop date (if 
stopped), seriousness, severity, action taken regarding the study drug, corrective treatment, 
outcome, and relationship to the study drug. In addition, a listing of subjects who 
prematurely discontinue from the study due to AEs will be provided as well as a listing of 
subjects who reported an SAE. 
12.6.2 Clinical Laboratory Tests 
Changes from Baseline in safety laboratory values (hematology, serum chemistry, and 
urinalysis) will be summarized with descriptive statistics for each treatment group at all 
applicable study visits. 
Shift tables will be presented for changes in safety laboratory values to summarize laboratory 
test results collected at Screening and Week 6. Normal ranges established by the central 
laboratory will be used to determine the shifts. A listing of all out-of-range laboratory test 
results at any assessment time point will also be provided. Determination of clinical 
significance for all out-of-range laboratory values will be made by each investigator and 
included in the listing. In addition, a listing of all clinically significant laboratory test results 
will be provided. 
12.6.3 Vital Signs 
Changes from Baseline in vital sign measurements will be summarized with descriptive 
statistics for each treatment group at all applicable study visits.

12.6.4 Concomitant Medications 
All previous therapies and concomitant medications will be classified based on terminology 
from the World Health Organization Drug Dictionary. Previous therapies and concomitant 
medications data will be presented in data listings. 
12.7 Interim Analyses 
No interim analyses are planned. 
12.8 Additional Statistical Considerations 
All statistical processing will be performed using SAS® version 9.3 or higher unless 
otherwise stated. A SAP, describing all statistical analyses, will be provided as a separate 
document prior to database lock. 
12.8.1 Analysis Populations 
Approximately 348 subjects with moderate or severe atopic dermatitis (defined as an IGA 
score of 3 or 4) will be enrolled and randomized in the study. With a 2:1 randomization ratio, 
it is anticipated that: 
• 
Approximately 232 subjects will be randomized to receive IDP-124 Lotion 
• 
Approximately 116 subjects will be randomized to receive IDP-124 Vehicle Lotion 
Efficacy analyses will be performed using the ITT population, the Week 6 PP population, 
and the Week 10 PP population. The ITT analysis set will be considered primary for the 
evaluation of efficacy. Safety analyses will be performed using the safety population during 
the treatment period (Baseline to Week 6), and during the post treatment period (Week 6 to 
Week 10). 
All subjects who are randomized and dispensed study drug will be included in the ITT 
population. 
All subjects who are randomized and receive at least 1 confirmed dose of study drug will be 
included in the safety population. 
All subjects in the ITT population who complete the Week 6 visit without any major protocol 
violations will be included in the Week 6 PP population. The Week 6 PP population will 
include subjects in the ITT population who did not meet any of the following criteria: 
 Violated the inclusion/exclusion criteria 
 Used an interfering concomitant medication prior to Week 6 
 Did not attend the Week 6 visit 
 Missed more than 1 post-baseline study visit prior to Week 6

 Have not been compliant with the dosing regimen (i.e., subjects must apply 80% 
120% of the expected applications of study medication during participation in the 
study) 
 Out of visit window at the Week 6 visit by more than ± 5 days 
 
Subjects that discontinue from the study due to an adverse event related to study treatment or 
documented lack of treatment effect (and/or worsening of condition) will be included in the 
Week 6 PP population.  
All subjects in the Week 6 PP population who complete the Week 10 visit without any major 
protocol violations will be included in the Week 10 PP population. Specifically, the Week 10 
PP population will include subjects in the Week 6 PP population who did not meet any of the 
following criteria:  
 
 Used an interfering concomitant medication between Week 6 and Week 10  
 Did not attend the Week 10 visit 
 Out of visit window at the Week 10 visit by more than ± 5 days  
 
Subjects that discontinue from the study due to an adverse event related to study treatment or 
documented lack of treatment effect will be included in the Week 10 PP population. 
Prior to breaking the blind, other additional criteria may be added to the list to accommodate 
for unforeseen events that occurred during the conduct of the trial that result in noteworthy 
study protocol violations. 
The number of subjects in each analysis population will be summarized. Reasons for study 
withdrawal during the blinded study will be summarized using frequencies and percentages 
by treatment group. 
12.8.2 Sample Size Determination 
The following power calculations were computed using the IGA efficacy results from the 
Pimecrolimus Lotion, 1% (Elidel) NDA 21-302. Considerations were given the change in 
expected entry level severity of the current study. Nquery Advisor Version 7.0 with the 
Fisher’s exact test option was used to calculate the power using a 2-sided test with an alpha 
of 0.05. The following table presents the efficacy estimates used in this power calculation.

* Success was defined as at least a 2-grade improvement from Baseline in the IGA score and an IGA score 
equating to “Clear” or “Almost Clear”. 
 
Overall, 232 IDP-124 Lotion treated subjects and 116 vehicle lotion treated subjects will 
have greater than 95% power to detect a statistically significant outcome for a 2-sided test 
with an alpha level of 0.05.  
It was noted that the estimates extracted from the above studies are based on the LOCF 
method of handling missing values while the proposed Phase 3 analysis will account for 
missing values using multiple imputations. The power stated above sufficiently exceeds 95% 
which will compensate for the difference in handling of missing data. 
12.8.3 Handling of Missing Data 
The primary method of handling missing efficacy data will be MCMC multiple imputation. 
This method does not rely on the assumption of data missing at random. Additionally, 
imputation will be conducted within each treatment group independently, so the pattern of 
missing observations in 1 treatment group cannot influence missing value estimations in 
another. 
For each efficacy variable (IGA, EASI, pruritus severity), the following steps will be 
performed to impute missing data: 
1. For each treatment group, create a data set containing subjects with observed 
values and those needing estimation by MCMC. The missing efficacy data in each 
data set will be filled in using the MCMC method 5 times to generate 5 data sets. 
The resulting data set for each treatment group will be combined into 1 complete 
data set for each imputation.  
2. Syntax: 
proc mi data=datain out=dataout seed=&seed. nimpute=5 <options>; 
where trtpn=(1 or 2); 
mcmc chain=multiple; 
var baseline week1 week2 week4 week6 week10; 
run; 
3. Imputed data will be used to determine dichotomized success/failure values, as 
appropriate. 
4. Each complete data set will be analyzed with the appropriate test (CMH, Analysis 
of Covariance). 
5. CMH statistics will be normalized using the Wilson-Hilferty transformation. 
6. The results from these analyses will be combined into a single inference using SAS 
PROC MIANALYZE.

A total of 6 random seeds will be needed for the multiple imputation process for the primary 
and secondary variables. The 6 random seeds have been prespecified by using a random 
number generator: 
 Seed for IGA endpoints for IDP-124 = 144527508 
 Seed for IGA endpoints for Vehicle = 622040939 
 Seed for EASI endpoints for IDP-124 = 1706910659 
 Seed for EASI endpoints for Vehicle = 2030081039 
 Seed for pruritus severity endpoints for IDP-124 = 1758840189 
 Seed for pruritus severity endpoints for Vehicle = 566468919

change in the conduct of the study can be instituted without prior written approval from the 
sponsor. 
14.8 Confidentiality/Publication of the Study 
All the data furnished to the investigator and his/her staff and all data obtained through this 
protocol will be regarded as confidential and proprietary in nature and will not be disclosed 
to any third party, except for the US FDA or other regulatory body, without written consent 
from the sponsor. 
The results of the study may be published or presented by the investigator(s) after the review 
by, and in consultation and agreement with the sponsor, and such that confidential or 
proprietary information is not disclosed. Prior to submission for publication or presentation, a 
copy of the final text should be forwarded by the investigator(s) to the sponsor or its designee 
for review and comment. Such comments shall aim to ensure the scientific integrity of the 
proposed publications and/or presentations and ensure that the data and material referring to 
the sponsor products and activities receive fair, accurate, and reasonable presentation. 
14.9 Study Termination 
The sponsor reserves the right to discontinue the study overall or at a particular clinical 
center at any time for reasons including but not limited to: 
 Emergence of effects that do not justify the benefit/risk relationship to the study 
population as a whole 
 Failure to comply with the protocol, GCP, or any other violation disturbing the 
appropriate conduct of the study 
 Failure to meet enrollment goals overall or at a particular clinical center 
If a study is terminated, the sponsor will promptly notify the investigator. After notification,

Data Handling and Record Keeping 
15.1 Inspection of Records 
Investigators must maintain detailed records on all study subjects who are enrolled in the 
study or who undergo screening. Data will be recorded in the subject’s source documents and 
in applicable study logs provided by the sponsor. Source documents include subject’s 
medical records, hospital charts, clinic charts, and the investigator’s subject study files, as 
well as the results of diagnostic tests (e.g., laboratory tests). All medical information obtained 
at each study visit must be recorded in the subject’s source documentation in real time as it is 
collected and then entered onto the eCRF by clinical center personnel.  
Subject-completed forms such as diaries and questionnaires are also considered source data. 
Only subjects are to record information in subject diaries and questionnaires. In no instance, 
should an investigator or clinical center personnel record any data or make changes to 
subject-completed forms. The investigator or designee should review subject-completed 
forms during study visits. If an entry is found to be illegible or a mistake is found (e.g., an 
incorrect year was recorded), the subject should be instructed to edit the entry by drawing a 
single line through the original entry, entering the new information, dating, and writing 
subject’s year of birth to acknowledge. 
Upon study completion or at any other time specified by the sponsor or designee, the 
appropriate study documents must be submitted to the sponsor.  
Telephone conversations and electronic mail with the subject, the sponsor, or the sponsor’s 
designee concerning the study must be recorded or kept on file.  
The investigator will allow representatives of the sponsor’s monitoring team, the governing 
IRB/IEC, the FDA, and other applicable regulatory agencies to inspect all study records, 
eCRFs, and corresponding portions of the subject’s clinic and/or hospital medical records at 
regular intervals throughout the study. These inspections are for the purpose of verifying 
adherence to the protocol, completeness and accuracy of the data being entered onto the 
eCRF, and compliance with FDA or other regulatory agency regulations. 
15.2 Case Report Forms 
Subject data required by this protocol are to be recorded on eCRFs. Subject data recorded on 
eCRFs during the study will be documented in a coded fashion. The subject will only be 
identified by the subject number and by their year of birth if also required. Confidentiality of 
subject records must be maintained to ensure adherence to applicable local privacy 
regulations.

The investigator and clinical center personnel will be responsible for completing the eCRFs. 
The investigator is required to verify that all of the requested information is accurately 
recorded on the eCRFs. All information requested on the eCRFs needs to be supplied, 
including subject identification, date(s), assessment values, etc, and any omission or 
discrepancy will require explanation. All information on eCRFs must be traceable to source 
documents.  
The study monitor will be responsible for reviewing and verifying the data recorded on the 
eCRFs, utilizing the original source documentation and will query discrepant findings. The 
investigator and clinical center personnel will be responsible for answering all queries. The 
eCRFs will be submitted to the sponsor or its designee(s) for quality assurance review, and 
statistical analysis. 
A copy of the eCRFs will be retained by the investigator at the conclusion of the study, who 
must ensure that it is stored in a secure place 
15.3 Retention of Records 
The investigator should properly store and maintain all study records in accordance with 
sponsor directives. All records relating to the conduct of this study are to be retained by the 
investigator until notified by the sponsor in writing that the records may be destroyed.

 Appendices  
17.1 Subject Instruction Sheet 
A thin layer of study drug should be applied twice daily at about the same time each day 
(approximately 12 hours apart) over the affected treatment areas indicated by the investigator 
for 6 weeks. A body diagram will be provided with your instructions and your study drug at 
your Baseline visit.  
 
Wash your hands before using the study drug. If you apply study drug after a bath or shower, 
make sure your skin is dry before application. 
 
Subjects and/or parent/legal guardian will squeeze study drug (about the size of a pea) onto a 
fingertip and then spread a thin layer of the study drug over the affected treatment area. If 
necessary, additional pea-sized amounts of study drug may be applied in increments (one pea 
size gently rubbed over a treatment area at a time) to cover all affected treatment areas. This 
is to be followed twice a day (at each application) over a 6 week period. Be sure to wash your 
hands after you apply the product. 
 
Refer to the body diagram to identify and document study drug application in the affected 
areas. It is important to continue to apply the study drug in all the areas that are identified in 
the body diagram even if improvement of signs and symptoms are noted.  
 
If new lesions are observed in between study visits, please document the new area(s) on the 
body diagram and bring with you to the next study visit. The study doctor will review the 
body diagram and any new lesions with you.  
 
The amount of study drug used by the subjects will be monitored by weighing each newly 
dispensed study drug container and weighing each returned study drug container at all 
applicable study visits.
