treated as an interim visit, with the exception of the collection of Investigational 
Product and Subject diaries from Subjects.  
Subjects will be admitted into the study after informed consent/assent has been 
obtained, a medical history and physical examination (with vital signs) have been 
performed and inclusion/exclusion criteria have been met. Subjects must have a 
clinical diagnosis of acne vulgaris to qualify for inclusion in this study. 
Each Subject will be randomly assigned in a double-blind fashion in a 1:1 ratio to 
treatment with the test product or the placebo control.  
At the screening/baseline visit, a physical examination (with vital signs) will be 
conducted. At each subsequent visit, the following procedures will be performed: 
counts of the facial comedones (open and closed), papules, pustules, nodules and 
cysts lesions will be performed, the Investigator’s Global Evaluation (IGA) will be 
performed and the signs and symptoms of irritation will be assessed.  
Safety will be assessed by the monitoring of all adverse events and the monitoring 
of any signs and symptoms of local irritation.

Comedone 
Non-inflammatory lesion; white, raised bumps caused by collections 
of oil and skin in pores.  Also known as white heads and pimples 
Open 
Comedone 
Non-inflammatory lesion; tiny, dark spots caused by a small plug in 
the opening of a follicle (pore) on the skin. Also known as 
blackheads 
Papule 
Inflammatory lesion; raised spot on the skin that is less than 1 
centimeter wide 
Pustule 
Inflammatory lesion; small, inflamed, pus-filled, blister-like lesions 
on the skin surface 
Nodules 
Large, hard bumps under the skin's surface 
Cysts 
A closed pocket or pouch of tissue. It can be filled with air, fluid, pus, 
or other material 
The Investigator’s Global Assessment (IGA) will be performed and documented using the 
definitions in Table 1 (above). 
Application site reactions [Redacted]will be recorded at each visit to allow a comparison 
between treatment groups. A detailed scale is presented in Section 5.5.  
Statistical Methods:  
 
Efficacy Analyses 
The efficacy assessment, superiority will be evaluated for each lesion type on the face 
using Analysis of Variance (ANOVA), with a statistical model containing terms for 
treatment and center, and with hypothesis testing at α = 0.05. The analyses will evaluate 
if the mean percent change (reduction) from baseline, in each lesion type, for the Test 
treatment differs from that of the Vehicle. In case of extreme departure from the 
assumptions of normal error, defined as skewness of residuals from ANOVA model 
exceeding 2 in absolute value, a ranked-based, nonparametric method will be used. 
Superiority will be established If the mean percent change (reduction) from baseline for 
the Test treatment, for each of the inflammatory and non-inflammatory lesion counts is 
greater than, and statistically different from (p<0.05), that for the Vehicle (Placebo) 
Control. For the proportions of subjects with treatment success on the IGA on the face 
the analysis will be conducted using two-sided, α = 0.05 Fisher’s exact test. Superiority 
will be established if the success proportion for the Test treatment is greater than, and 
statistically different from (p<0.05), that of the Vehicle. 
In order to preserve an overall type-I error (alpha) of 5%, a hierarchical evaluation 
scheme will be employed. The comparisons of interest are: 
1. percent change from baseline in the inflammatory lesion counts 
2. percent change from baseline in the non-inflammatory lesion counts 
3. proportions of subjects with treatment success on the IGA 
These comparisons will be performed insequence for weeks 12, 10, 8, 6, 4, and 2. 
Statistical testing will begin with comparison 1. If statistical significance is attained with 
comparison 1 (p < 0.05), then a claim of superiority for comparison 1 can be made and 
the next comparison in the hierarchical evaluation scheme can be tested for statistical 
significance. If statistical significance is not attained for comparison 1 (p ≥ 0.05), then 
testing of all subsequent comparisons is stopped. The hierarchical, conditional-stepwise 
evaluation scheme allows for each comparison to be evaluated at the 5% level, while 
preserving an overall type I error rate of no more than 5%.

For Subgroup descriptive analyses comparing each lesion type and proportion of 
subjects with the treatment success on the body will be conducted for information 
purpose. 
Efficacy results will be used to calculate the sample size for the Phase 3 studies. 
Analysis of application site reactions 
A descriptive analysis comparing the application site reactions for each treatment group 
will be conducted with regard to the expected and unexpected application site reactions. 
Application sete reactions will also be compared between applications on the face and 
on the body. 
Summary of Subjects who terminate prematurely 
Reasons for premature termination will be summarized by treatment group. 
Concomitant medication 
The start and stop date of concomitant medication use during the study will be provided 
in the data set in addition to the reason for the medication use.  
Safety Analyses 
Safety analyses will be conducted on the safety population. Safety Incidence of all 
adverse events reported during the study will be summarized using the MedDRA 
dictionary by treatment group, body system, severity and relationship to study drug. 
The report of AEs will include date of onset, description of the AE, and date of resolution. 
Formal statistical evaluation(s) of the comparability of the two treatment groups will be 
conducted with regard to the frequency and severity of any AE that occurs in at least 5% 
of the subjects in either treatment group.

1. INTRODUCTION AND BACKGROUND 
Acne vulgaris is a disorder of the pilosebaceous unit. Found in greatest concentrations on the face, 
upper back, shoulders and chest, a pilosebaceous unit is made up of a hair follicle lined with 
keratinocytes, a sebaceous gland, and a hair. The sebaceous gland produces a substance called 
sebum. Although sebum normally empties onto the skin’s surface through the openings of the 
follicles, the follicles may become plugged with hair, sebum and keratinocytes, resulting in 
comedones. Bacteria normally found on the skin may grow in the comedones, resulting in 
inflammation. Therefore, acne vulgaris is a multi-factorial disease, caused by the interplay of excess 
sebaceous gland secretion, bacterial growth, keratinization abnormalities, and immune reactivity. 
Acne is clinically characterized by the formation of open and closed comedones (non-inflammatory 
lesions), papules, pustules and nodulocystic lesions (inflammatory lesions). The highest 
concentration of lesions is often found on the face, shoulders, upper back, and chest. Although acne 
vulgaris is most common in adolescents and young adults, it can continue to occur in adults older 
than 50 years of age. 
Taro has developed a new formulation [Redacted as ATS55], for treatment of acne in patients 9 years 
of age and older. [Redacted] The current study is designed to evaluate the safety and efficacy of this 
new formulation. Efficacy results will be used to calculate the sample size and establish endpoints for 
the Phase 3 studies. 
2. OBJECTIVES  
The objective of this study to evaluate the efficacy and safety of [Redacted as ATS55] (Taro 
Pharmaceuticals U.S.A, Inc.) in the treatment of acne vulgaris.  
3. STUDY OVERVIEW 
Subjects will be admitted into the study after informed consent/assent has been obtained, a medical 
history and physical examination (with vital signs) have been performed and inclusion/exclusion 
criteria have been met. Subjects must have a clinical diagnosis of acne vulgaris to qualify for inclusion 
in this study. 
Approximately 300 Subjects will be assigned in a 1:1 ratio to treatment with the test product, 
[Redacted as ATS55] (Taro Pharmaceuticals U.S.A., Inc.) or placebo (vehicle of the test product) in 
this multiple-center, double-blind, randomized, placebo controlled, parallel-group study. The assigned 
Investigational Product will be self-applied topically to the face and other affected body areas once 
daily for 84 consecutive days. The Investigational Product should be applied around the same time 
every day after the Subject’s treatment areas have been washed with a non-medicated cleanser, and 
warm water. For the purposes of this study, the face is considered to start at the hairline and end at 
the jaw line and excludes the eyes, the lips and all mucous membranes. The body is considered as at 
least one affected area: back, chest and/or shoulders. Subjects will be required to use diaries to 
document the date of study treatments, any missed treatments and the occurrence of all adverse 
events. 
The duration of each Subject’s participation in the study will be 84 days. Scheduled study visits will 
include:  
Visit 1: Screening/Baseline Visit (Day 0);  
Visit 2: Interim Visit (Week 2 / Day 14 ± 4 Days);  
Visit 3: Interim Visit (Week 4 / Day 28 ± 4 Days); 
Visit 4: Interim Visit (Week 6 / Day 42 ± 4 Days); 
Visit 5: Interim Visit (Week 8 / Day 56 ± 4 Days); 
Visit 6: Interim Visit (Week 10 / Day 70 ± 4 Days);  
Visit 7: End of Treatment Visit (Week 12 / Day 84 ± 4 Days) 
Visit 8*: Follow up phone call (Week 13 / Day 91 ± 4 Days) 
*if required for on-going AEs based on PI decision 
A nine (9) day window (i.e., ± 4 days) will be considered acceptable for each scheduled visit following

the baseline visit. 
  
An Unscheduled Visit is allowed at any time, for any reason, if in the Principal Investigator’s opinion it 
is warranted. If a Subject is discontinued from the study during an Unscheduled Visit, the 
Unscheduled Visit will be referred to as an Early Discontinuation Visit and all procedures scheduled 
for Visit 7 will be performed. If the Unscheduled Visit is not an Early Discontinuation Visit (i.e., the 
Subject will continue to take part in the study), then all procedures will be performed and treated as 
an interim visit, with the exception of the collection of Investigational Product and Subject diaries from 
Subjects.  
If the Principal Investigator determines that the Subject’s condition has worsened to the degree that it 
is unsafe for the Subject to continue in the study, the Subject may be discontinued from the study as 
a treatment failure and the Subject may be treated using the standard care.  
At the screening/baseline visit, a physical examination (with vital signs) will be conducted. At each 
subsequent visit, the following procedures will be performed: counts of the facial comedones (open 
and closed), papules, pustules, nodules and cysts lesions will be performed, the Investigator’s Global 
Evaluation (IGA) will be performed and the signs and symptoms of irritation will be assessed.  
Safety will be assessed by the monitoring of all adverse events and the monitoring of any signs and 
symptoms of local irritation. 
At Visit 1, an informed consent/assent and HIPAA authorization will be obtained from the potential 
study Subject before any study procedures take place. After the Subject has been 
consented/assented, the Subject’s medical history will then be documented, including the Subject’s 
concomitant medications. A urine pregnancy test will be performed for female Subjects of 
childbearing potential. All female Subjects are considered to be of childbearing potential unless they 
are premenarchal, have been surgically sterilized or have been postmenopausal for at least 1 year. A 
baseline acne grade will be assigned to the Subject using the Investigator’s Global Assessment (IGA) 
and a baseline lesion count will be performed. The Subject will undergo a brief physical examination, 
including the recording of vital signs. The Subject will be evaluated for signs and symptoms of local 
irritation. The Subject will be reviewed against the inclusion/exclusion criteria. Blinded Investigational 
Product will be dispensed to Subjects who meet all of the inclusion and exclusion criteria using the 
lowest patient randomization number available at that investigative site. Subjects will be instructed on 
the application of Investigational Product and completion of Subject diaries. The Investigational 
Product should not be opened in the clinic. The first application of Investigational Product will be 
performed by the Subject at home. 
Subjects will return to the study site for visits at Weeks 2, 4, 6, 8, 10, and 12. The Subject’s 
concomitant medications will be reviewed and documented. A urine pregnancy test will be performed 
for female Subjects of childbearing potential. The Subject will be evaluated for signs and symptoms of 
local irritation and any adverse events will be documented. The Subject’s facial acne will be assessed 
using the IGA, the Subject’s lesions will be counted and these results will be documented. The 
Subjects are instructed to bring their used Investigational Product and their study diaries to each 
study visit. Compliance with drug applications will be assessed at each visit.  Additional units of 
Investigational Product will be dispensed and each Subject will receive new diaries during visits at 
Weeks 2, 4, 6, 8, and 10. In addition, all Investigational Product and diaries will be collected from the 
Subject during each scheduled visit or the Early Discontinuation Visit.

4. STUDY POPULATION  
4.1 Number of Subjects  
This multi-center study will be comprised of Subjects presenting with a clinical diagnosis of acne 
vulgaris of severity grade 2, 3, or 4 using the IGA.  Approximately 300 Subjects will be enrolled into 
the study. Male and female Subjects, ≥ 9 years of age, of any race, who meet the inclusion and 
exclusion criteria, will be enrolled in approximately 5 study sites. Approximately equal numbers of 
male and female subjects will be enrolled to each of the study arms.  
 
4.2 Inclusion Criteria  
[Redacted]
  
4.3 Exclusion Criteria 
[Redacted] 
4.4 Prohibited Medications, Procedures, and Activities 
[Redacted] 
4.5 Precautions  
The following precautions are to be taken during this study:  
1. To minimize exposure to sunlight, a wide-brimmed hat or other protective clothing should 
be worn.  The non-comedogenic sunscreen with a SPF 15 rating or higher provided by the 
Sponsor may be used.  
2. Exposure to weather extremes including strong wind or cold should be avoided. 
3. The Investigational Product should not be applied to cuts, abrasions or eczematous skin. 
4. The Investigational Product should not be applied to the eyes, the lips, the angles of the 
nose or any mucous membranes. 
If a reaction suggesting sensitivity or chemical irritation occurs, the Principal Investigator should 
assess the Subject’s condition as soon as possible (i.e., during an Unscheduled Visit) and determine 
whether treatment should be discontinued. If the Subject is discontinued from the study during an 
Unscheduled Visit, procedures from Visit 4 should be followed and the visit will be referred to as an 
Early Discontinuation Visit. 
4.6 Subject Disposition and Discontinuation 
Investigators are urged to enroll only those eligible Subjects who are likely to complete the entire 
study and who are willing to comply with the protocol-specified procedures.  It is the right and duty of 
the investigator to interrupt the treatment of any Subject whose health or well-being may be 
threatened by continuation in this study, or who may be experiencing unmanageable factors that may 
interfere with the study procedures and/or the interpretation of study results.  Such Subjects should 
be withdrawn from the study rather than continued under a modified regimen. 
Subjects will be removed from the study for any of the following reasons:  
• 
If the Subject withdraws his or her consent for any reason; 
• 
If the Subject’s condition has worsened beyond grade 4 or to the degree that the Principal 
Investigator feels it is unsafe for the Subject to continue in the study; 

 
 
 
CONFIDENTIAL 
 
 
 
2 August 2016 
Protocol:  ADPS 1602 
 Page 15 of 36 
  
 
• 
If the Subject’s drug code is unblinded; 
• 
If an adverse event occurs for which the Subject desires to discontinue treatment or the 
Principal Investigator determines that it is in the Subject’s best interest to be discontinued; 
• 
If there is a significant protocol violation; 
• 
If the Subject is lost to follow-up;  
• 
If the Subject becomes pregnant; 
• 
If the Subject becomes a prisoner or become involuntarily incarcerated;  
• 
Any other reason that may affect the outcome of the study or the safety of Subjects; or 
• 
Termination of the study by the Sponsor. 
A significant protocol violation is defined as any Subject or Investigator activity that could have 
possibly interfered with the therapeutic administration of the treatment or the precise evaluation of 
treatment efficacy. 
The reasons for a Subject discontinuation will be documented. If a Subject is discontinued from the 
study for any reason, the procedures scheduled for Visit 7 will be completed and any outstanding 
data and study drug should be collected if possible. Data, in addition to the reason for discontinuation 
and the date of removal, will be documented on the End of Study eCRF. 
Before a Subject is considered to be lost to follow-up, the Principal Investigator will document all 
attempts to reach the Subject twice by telephone and will send a certified follow-up letter. 
In the event that a Subject discontinues from the study at any time due to an adverse event, the 
reason for discontinuation, the nature of the event and its clinical course must be fully documented. 
For such a Subject, the Principal Investigator must strive to follow the Subject until the adverse event 
has resolved, become clinically insignificant, is stabilized or the Subject is lost to follow-up. Should a 
serious adverse event be noted, procedures stated in Section 10.3 must be followed. 
 
5. SAFETY AND TOLERABILITY EVALUATIONS 
5.1 General Safety Evaluations 
A complete medical history will be obtained for the Subject’s current and past medical conditions. 
Significant medical history should include, but not be limited to, evidence of hypertension, lipid 
disorders, obesity, heart attack, stroke, congestive heart failure, kidney disease, auto immune 
disease and gestational diabetes. Significant surgical history should include, but not be limited to, 
removal of blockage from an artery and gallbladder removal. 
Concomitant medications, including the use of sunscreen, in addition to the reason for the medication 
use, will be assessed at baseline and at each subsequent study visit. The start and stop date of 
concomitant medication use during the study should be provided in the data set in addition to the 
reason for the medication use. 
A brief physical examination will be performed at baseline. The physical examination will include, at a 
minimum, examination of the Subject’s general appearance, skin, HEENT (head, eyes, ears, nose 
and throat), heart, lungs, musculoskeletal system, neurological system, lymph nodes, abdomen and 
extremities. The Subject’s body weight will also be measured while the Subject is lightly clothed (e.g., 
no coat or shoes).

Protocol:  ADPS 1602 
 Page 16 of 36 
  
 
5.2 Physical Examination 
The investigator, sub-investigator or appropriately delegated designee, (Physician’s Assistant, 
Advanced Registered Nurse Practitioner, and Registered Nurse as per local regulations) will perform 
a brief physical examination, prior to the Subject starting study drug.   
Vital signs, including blood pressure, pulse rate, respiratory rate and oral body temperature will be 
documented at Visit 1. Vital signs will be measured after the Subject has rested in a seated position 
for at least 5 minutes. 
The Subject’s body weight will also be measured while the Subject is lightly clothed (e.g., no coat or 
shoes). Height will be measured without shoes. 
 
5.3 Pregnancy Test 
All female Subjects of childbearing potential will undergo a urine pregnancy test during Visit 1 and at 
each subsequent study visit. All female Subjects are considered to be of childbearing potential unless 
they are premenarchal, have been surgically sterilized or have been postmenopausal for at least 1 
year. Women of childbearing potential, in addition to having a negative urine pregnancy test, must be 
willing to use an acceptable form of birth control during the study from the day of the first dose 
administration to 30 days after the last administration of study drug For the purpose of this study the 
following are considered acceptable methods of birth control: oral or injectable contraceptives, 
contraceptive patches, Depo-Provera® (stabilized for at least 3 months), NuvaRing® (vaginal 
contraceptive), Implanon™ (contraceptive implant), double barrier methods (e.g. condom and 
spermicide), IUD, or abstinence with a 2nd acceptable method of birth control should the Subject 
become sexually active.  A sterile sexual partner is NOT considered an adequate form of birth 
control.Subjects on hormonal contraception must be stabilized on the same type for at least three 
months prior to enrollment in the study and must not change the method during the study.  Subjects 
who had used hormonal contraception and stopped must have stopped no less than three months 
prior to the study. 
 
5.4 Concomitant medications 
Concomitant medications, including the use of sunscreen, in addition to the reason for the medication 
use, will be assessed at baseline and at each subsequent study visit. The start and stop date of 
concomitant medication use during the study should be provided in the data set in addition to the 
reason for the medication use. 
A record of concomitant medications taken by the Subject is to be obtained using generic name, if 
known, with the corresponding indication. The medications to be recorded will include prescription 
and over-the-counter (OTC) medications and dietary supplements.  All medications taken on a 
regular basis, including aspirin and acetaminophen, should be recorded. 
 
5.5 Signs/Symptoms of Local Irritation  
At each study visit, beginning at Visit 1, Subjects will be evaluated for any signs and symptoms of 
local irritation [Redacted]. Baseline values will be used for comparative purposes against the scores 
documented at subsequent visits for each treatment group. Each Subject will be assigned a severity 
score by an Investigator based on the scale in Table 2.  
Application site reactions [Redacted] will be recorded at each visit to allow a comparison between 
treatment groups.

CONFIDENTIAL 
 
 
 
2 August 2016 
Protocol:  ADPS 1602 
 Page 17 of 36 
  
 
Subjects with a baseline irritation score of 3 (severe, marked/intense) will not be enrolled. After 
baseline, severe irritation (i.e., grade 3, described as severe or marked/intense) that requires 
treatment will be reported as an adverse event. 
Local irritation reactions in the treatment area are common and the Investigator may instruct Subjects 
to stop the application of treatment (“rest period”) to reduce Subject discomfort and to allow local skin 
reactions to subside based upon the Investigator’s clinical assessment.   Treatment should resume as 
soon as the reaction subsides sufficiently to allow reapplication. All dose modifications must be 
reported on the appropriate Study Medication Log & Dosing Compliance eCRF. 
The treatment period should not be extended beyond 12 weeks due to missed doses or rest periods.  
Subjects whose condition worsens or lesions do not respond to treatment should be re-evaluated by 
the Investigator and management reconsidered.  
5.6 Adverse Events  
An adverse event is defined as any untoward medical occurrence (sign, symptom or laboratory 
finding), regardless of severity and whether or not attributed to the investigational product. All adverse 
events, whether observed by an Investigator or Study Coordinator or reported by the Subject, 
whether related to study drug or not related to study drug, shall be documented on the eCRF and 
Subject records, together with details, i.e. date of onset, the duration and intensity of each episode, 
the action taken, the relationship to the investigational product and the degree of severity, the 
seriousness and the outcome.

CLINICAL EVALUATIONS  
An examination of the Subject’s acne will be performed at baseline and at each subsequent visit.  
During the dermatologic examination, evaluations to determine efficacy of treatment will be 
conducted, including lesion counts and grading of the Subject’s acne using the criteria outlined in the 
IGA.  
Preferably a single Investigator (i.e., Principal Investigator or Sub-Investigator) or qualified staff will 
perform evaluations of efficacy (i.e., lesion counts and IGA) for each Subject at each visit from the 
beginning to the end of the Subject’s participation to maintain consistency; however, only up to two 
Investigators or qualified staff may perform evaluations of efficacy for a single Subject if necessary. 
[Redacted]. 
 
6.1 Lesion Counts and Investigator’s Global Assessment 
At each visit, an Investigator or qualified staff will assess the Subject’s acne by counting the number of 
open and closed comedones, pustules, papules and nodulocystic lesions. All lesions will be counted, 
including those present on the nose. An Investigator will also assess the overall status of the Subject’s 
acne vulgaris using the IGA. The IGA scores for each visit will be documented on the eCRF. For the 
purposes of this study, the face is considered to start at the hairline and end at the jaw line and 
excludes the eyes, the lips and all mucous membranes. The body is considered as at least one 
affected area: back, chest and/or shoulders.

Section 8.7) 
 
7.4 Unscheduled Visits and Early Discontinuation Visit 
An Unscheduled Visit is allowed at any time, for any reason, if in the Principal Investigator’s opinion it 
is warranted. If the Unscheduled Visit is due to an AE, the Principal Investigator will determine 
whether additional visits are needed.  
If a Subject is discontinued from the study during an Unscheduled Visit, the Unscheduled Visit will be 
referred to as an Early Discontinuation Visit and all procedures scheduled for Visit 7 will be 
performed. If the Unscheduled Visit is not an Early Discontinuation Visit (i.e., the Subject will continue 
to take part in the study), then all procedures scheduled for that interim visit  will be performed, with 
the exception of the collection of Investigational Product and Subject diaries from Subjects.   
If the Subject’s condition has worsened to the degree that it is unsafe for the Subject to continue in 
the study, the Subject may be discontinued from the study as treatment failure and a standard of care 
treatment may be advised at the Principal Investigator’s discretion.

digit unique randomization number will be designated as the Subject number.  Only one Subject number 
will be assigned to each Subject.  The Subject will maintain the same number and treatment assignment 
throughout the study.  [Redacted]. 
 
8.4 Treatment Assignment  
The subject study identification number will correspond to a computer-generated randomization schedule 
assigning that number to one of the three study treatment groups. The randomization scheme will be 
generated, in blocks of 6, so that the test product and the vehicle (placebo) control are assigned in a 1:1 
ratio. The subject numbers at the site will correspond to the order in which subjects are enrolled into the 
study. 
 
8.5 Administration of Investigational Product  
At baseline, and as needed during the study, Investigational Product will be dispensed to randomized 
Subjects along with a diary. Each Subject will also receive written study instructions, which detail the 
proper application method of the Investigational Product and general study instructions.  
Subjects will apply a  thin layer of study medication to cover the entire face and other affected body areas 
once daily, avoiding contact with the mouth, eyes and open wounds. For the face applications subjects 
will be instructed to apply the product to the hand or cotton pad and gently rub it to the entire face. For the 
body applications (e.g., on the back, chest and shoulders), the product will be applied to the affected 
areas and gently rubbed into the skin. Subjects will wash their hands before and after administration of 
the Investigational Product. Investigational Product will be applied in this manner for 84 consecutive days. 
Subjects will be required to use diaries to document the date of study treatments, any missed treatments 
and the occurrence of all adverse events. [Redacted].

Subjects will be instructed not to bathe, shower, wash or swim for at least 4 hours after the application of 
the Investigational Product.  
At each visit during the study, the Investigator or designee should review proper application of the 
Investigational Product. 
 
8.6 Assessment of Compliance  
Compliance with scheduled application of Investigational Product will be determined from the 
Subject’s diary. The Subject will be instructed to use the diary to document all doses taken by 
checking the yes or no box for the appropriate date. In addition, Subjects will be instructed to 
document all AEs on the diary. Used Investigational Product will be returned to the study site at each 
scheduled visit or Early Discontinuation Visit. If the subject does not return the Diary, patient-reported 
dosing compliance will be recorded in the source notes and will be used to derive compliance 
between those visits. 
  
8.7 Investigational Product Accountability  
It is the responsibility of the Principal Investigator to ensure that the current disposition of the 
Investigational Product is maintained at each study site where Investigational Product is inventoried 
and dispensed. When a drug shipment is received at a study site, the Principal Investigator or the 
Principal Investigator’s Designee must inventory the drug and sign the receipt form provided with the 
shipment. The receipt form should be faxed to the drug depot as per instructions provided on the 
receipt.  A copy of the receipt should remain at the site. 
The Investigator will not supply study test articles to any person not enrolled in this study, or to any 
physician or scientist except those named as sub-investigators. 
A Drug Accountability Log will assist study site staff in maintaining inventory records of study drug. 
Subjects must return used, partially used or unused Investigational Product to the study site staff so 
that any remaining drug supplies can be accounted for and noted in the Drug Accountability Log. 
Weights of all dispensed units of the Investigational Product will be obtained before dispensing and 
after the units are returned to the study site. 
The original Drug Accountability Log must be provided to the study monitor at the conclusion of the 
study and a copy should remain at the study site.  
 
8.8 Retention of Study Drug Samples  
A sufficient amount of the study drug will be randomly selected for retention by the packaging facility and 
shipped 
to 
the 
storage 
facility 
for 
a 
long 
term 
storage. 
[Redacted]
 
8.9 Return of Clinical Supplies  
All used and unused containers of Investigational Product may be returned to the Drug Labeling, 
Packaging and Shipping Facility for destruction or be destructed at the site after study close-out and 
final drug accountability is reconciled.

STATISTICAL METHODS  
9.1 Scientific and Statistical Considerations of the Study Design 
The current study is designed to evaluate the safety and efficacy of this new formulation. Efficacy results 
will be used to calculate the sample size and establish endpoints for the Phase 3 studies. 
The study was designed following FDA Guidance for Industry (Draft). Acne Vulgaris: Developing Drugs 
for Treatment. Division of Dermatologic and Dental Drug Products. FDA September 2005. 
 
9.2 Sample Size Rationale  
The primary statistical analyses of interest are the differences between the Test and the Placebo 
(Vehicle) treatments in the mITT population  for mean  inflammatory and non-inflammatory lesion 
count reductions, and for proportions of subjects with clinical success on the IGA for. In this Phase 2 
study, approximately 300 Subjects will be enrolled to obtain at least 286 evaluable in the mITT 
Subjects (143 in each treatment group).  
9.3 Randomization and Unblinding Procedures  
Subjects will be randomly assigned in a 1:1 ratio to receive the test product or the vehicle (placebo) 
control. The randomization assignment will be generated using SAS®  by an independent statistician, 
not involved with the study. 
The Drug Labeling, Packaging facility will hold the randomization code throughout the conduct of the 
study in order to minimize bias.  A sealed copy of the randomization scheme (as a scratch off portion 
of the product label attached to the drug accountability page) will be retained at the study site. In the 
event of an emergency, the Subject-specific treatment may be identified; however, every effort should 
be made to maintain the blind. Where possible, the CRO medical monitor should be contacted before 
breaking the blind for any patient. The Sponsor must be notified in the event the blind is broken. 
The treatment assignments will remain blinded until the final database is closed. 
 
9.4 Significance Level  
All statistical tests will be two-sided at a significance level of α = 0.05. No adjustment will be made for 
multiplicity. 
 
9.5 Datasets to be Analyzed  
Two analysis populations will be used in the analysis of the clinical data: 
1. A safety population Subject is any individual who was randomized into the study and used at least 
one dose of investigational product. 
2. The Modified ITT (mITT) population includes all Safety population Subjects who have met all 
inclusion/exclusion criteria and return for at least one post-baseline efficacy evaluation.  
.  
Efficacy analyses will be performed on the ITT.  All efficacy data will be listed by treatment and Subject 
in data listings.

9.6 Handling of Missing Data 
Missing safety data will not be imputed. In the analysis of efficacy on mITT population for subjects who 
discontinue from the study due to lack of efficacy, their IGA success endpoint will always be imputed 
as failure. In all other cases missing endpoints will be imputed with LOCF by carrying forward the last 
available post-baseline assessment.  
 
9.7 Measures 
Lesion Counts will be performed using the following definitions: 
Definition of inflammatory and non-inflamatory lesions 
Lesion Type 
Definition 
Closed 
Comedone 
Non-inflammatory lesion; white, raised bumps caused by collections of oil 
and skin in pores.  Also known as white heads and pimples 
Open 
Comedone 
Non-inflammatory lesion; tiny, dark spots caused by a small plug in the 
opening of a follicle (pore) on the skin. Also known as blackheads 
Papule 
Inflammatory lesion; raised spot on the skin that is less than 1 centimeter 
wide 
Pustule 
Inflammatory lesion; small, inflamed, pus-filled, blister-like lesions on the 
skin surface 
Nodules 
Large, hard bumps under the skin's surface 
Cysts 
A closed pocket or pouch of tissue. It can be filled with air, fluid, pus, or 
other material 
The Investigator’s Global Assessment (IGA) will be performed and documented using the definitions in 
the table, below:

9.8 Demographics and Baseline/Randomization Characteristics   
Demographic and baseline/randomization characteristics will be evaluated for comparability across 
treatment groups for the ITT and safety populations. [Redacted].  
 
9.9 Safety Assessment  
The extent of exposure will be summarized using descriptive statistics. No inferential analyses are 
planned. 
Incidence of all adverse events reported during the study will be summarized using the MedDRA 
dictionary by treatment group, body system, severity, and relationship to study drug.   The 
comparability of the Test and Placebo treatment groups for the frequency and severity of any adverse 
event that occurs in at least 5% of the Subjects in either treatment group will be evaluated using 
categorical methods. 
Incidence of concomitant medications will be summarized by treatment group. 
Safety analyses will be performed on the safety population. All safety data will be listed by treatment 
and Subject in data listings. 
 
9.10 
Efficacy Assessment  
The efficacy assessment, superiority will be evaluated for each lesion type on the face using Analysis of 
Variance (ANOVA), with a statistical model containing terms for treatment and center, and with hypothesis 
testing at α = 0.05. The analyses will evaluate if the mean percent change (reduction) from baseline, in 
each lesion type, for the Test treatment differs from that of the Vehicle. In case of extreme departure from 
the assumptions of normal error, defined as skewness of residuals from ANOVA model exceeding 2 in 
absolute value, a ranked-based, nonparametric method will be used. Superiority will be established If the

2 August 2016 
Protocol:  ADPS 1602 
 Page 27 of 36 
  
 
mean percent change (reduction) from baseline for the Test treatment, for each of the inflammatory and 
non-inflammatory lesion counts is greater than, and statistically different from (p<0.05), that for the Vehicle 
(Placebo) Control. For the proportions of subjects with treatment success on the IGA on the face the 
analysis will be evaluated by Fisher's exact test. Superiority will be established if the success proportion for 
the Test treatment is greater than, and statistically different from (p<0.05), that of the Vehicle. 
In order to preserve an overall type-I error (alpha) of 5%, a hierarchical evaluation scheme will be 
employed. The comparisons of interest are: 
1) percent change from baseline in the inflammatory lesion counts 
2) percent change from baseline in the non-inflammatory lesion counts 
3) proportions of subjects with treatment success on the IGA 
These comparisons will be performed in sequence for weeks 12, 10, 8, 6, 4, and 2. 
Statistical testing will begin with comparison 1. If statistical significance is attained with comparison 1 (p < 
0.05), then a claim of superiority for comparison 1 can be made and the next comparison in the 
hierarchical evaluation scheme can be tested for statistical significance. If statistical significance is not 
attained for comparison 1 (p ≥ 0.05), then testing of all subsequent comparisons is stopped. The 
hierarchical, conditional-stepwise evaluation scheme allows for each comparison to be evaluated at the 
5% level, while preserving an overall type I error rate of no more than 5%.  
For Subgroup descriptive analyses comparing each lesion type and proportion of subjects with the 
treatment successon the body will be conducted for information purpose.  
Efficacy results will be used to calculate the sample size for the Phase 3 studies. 
 
9.11 
Analysis of Application Site Reactions 
A descriptive analysis comparing the application site reactions for each treatment group will be 
conducted with regard to the expected and unexpected application site reactions. Application sete 
reactions will also be compared between applications on the face and on the body.  
 
9.12 
Concomitant Medication 
The start and stop date of concomitant medication use during the study will be provided in the data 
listings in addition to the reason for the medication use.

ADVERSE EVENTS  
10.1 
Reporting of Adverse Events  
Any untoward medical occurrence in a Subject or clinical-trial Subject administered a medicinal product 
and which does not necessarily have to have a causal relationship with this treatment. An adverse event 
can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with 
the use of a medicinal product, whether or not considered related to the medicinal product. 
Any adverse event associated with the use of a drug in humans, whether or not considered product-
related, including the following: An adverse event occurring in the course of the use of a drug product in 
professional practice; an adverse event occurring from drug overdose whether accidental or intentional; an 
adverse event occurring from drug abuse; an adverse event occurring from drug withdrawal; and any 
failure of expected pharmacological action. Reporting an adverse event does not necessarily reflect a 
conclusion that the product caused or contributed to the adverse event. 

 
 
 
CONFIDENTIAL 
 
 
 
2 August 2016 
Protocol:  ADPS 1602 
 Page 28 of 36 
  
 
All adverse events, whether observed by an Investigator or Study Coordinator or reported by the Subject, 
whether related to study drug or not related to study drug, shall be documented in the CRF and Subject 
records, together with details of the duration and intensity of each episode, the action taken, the 
relationship to the Investigational Product and the degree of severity, the seriousness and the outcome. 
[Redacted]The Principal Investigator must strive to follow the Subject until the adverse event has resolved, 
becomes clinically insignificant, is stabilized or the Subject is lost to follow-up. The Principal Investigator 
must immediately report to the Contract Research Organization, by telephone and follow-up in writing, all 
study drug discontinuations due to adverse events.  
Assessment of Severity  
The intensity or severity of an adverse event (AE) is characterized as:  
• 
Mild: an AE that is easily tolerated  
• 
Moderate: an AE sufficiently discomforting to interfere with daily activity  
• 
Severe: an AE that prevents normal daily activities  
Relationship to Study Medication  
The relationship is characterized as:  
• 
Not Related: This applies to any AE that is clearly not related to use of the study drug.  
• 
Possible: This means the association of the AE with the study drug is unknown; however, 
a relationship between drug and event cannot be ruled out.  
• 
Probable: There is a reasonable temporal relationship between the use of the study drug 
and the AE. Based upon the Principal Investigator’s clinical experience, the association of 
the event with the study drug seems likely.  
• 
Definite: The AE occurs following the application of the study drug and it cannot be 
reasonably explained by any known characteristics of the Subject’s clinical state, 
environmental or toxic factors or other modes of therapy administered to the Subject. It 
disappears or decreases upon discontinuation of the study drug and reappears on a re-
challenge of the investigational product.  
 
10.2 
Pregnancy 
Female Subjects of childbearing potential must have been using and must agree to continue to use 
accepted methods of birth control, throughout the study. All female Subjects are considered to be of 
childbearing potential unless they are premenarchal, have been surgically sterilized or have been 
postmenopausal for at least 1 year. Abstinence is an accepted method of birth control. Alternatively, 
any of the following methods of birth control are acceptable: oral contraceptives, contraceptive 
patches/implants (e.g., Norplant®), Depo-Provera®, double barrier methods (e.g., condom and 
spermicide) or IUD. Prior to study enrollment women of child bearing potential must be advised of the 
importance of avoiding pregnancy during study participation.  
A negative result of a pregnancy test having a minimum sensitivity of at least 50mIU/ml for hCG 
should be obtained, prior to study participation, at Visit 1. Pregnancy testing will also be performed at 
every study visit and the results of all pregnancy tests (positive or negative) will be documented. 
If following initiation of study treatment, it is subsequently discovered that a study Subject is pregnant 
or may have been pregnant at the time of Investigational Product exposure, the Investigational 
Product will be permanently discontinued. The Principal Investigator must immediately notify the 
Medical Monitor of this event. 
Protocol-required procedures for study discontinuation and follow-up must be performed on the 
Subject. Other appropriate pregnancy follow-up procedures should be considered if indicated. In

addition, the Principal Investigator must report to the sponsor follow-up information regarding the 
course of the pregnancy, including perinatal and neonatal outcome. Infants should be followed for a 
minimum of eight weeks after birth.   
 
10.3 
Serious Adverse Events  
An Adverse Event or Suspected Adverse Reaction is considered ‘‘serious’’ if, in the view of either 
the investigator or sponsor, it results in any of the following outcomes: 
• 
Death  
• 
A life threatening adverse event; (Note: the term “life-threatening” as used here refers to an 
event in which the Subject was 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.)  
• 
In-Subject hospitalization or prolongation of existing hospitalization  
• 
A persistent or significant disability/incapacity (substantial disruption of the ability to conduct 
normal life functions) 
• 
A congenital anomaly/birth defect 
• 
Any “other” important medical event  
Important medical events that may not result in death, be life-threatening or require hospitalization 
may be considered Serious Adverse Events when, based on 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.  
Regardless of the above, any additional adverse events, which the Principal Investigator considers 
significant, should be immediately reported to the Contract Research Organization. 
Any Serious Adverse Event, whether deemed drug-related or not, must be reported by the 
Investigator to the Contract Research Organization (CRO) Medical Monitor by telephone within 24 
hours after the Principal Investigator or Study Coordinator becomes aware of its occurrence.  The 
Principal Investigator or the Principal Investigator’s Designee must complete a Serious Adverse Event 
(SAE) Form and fax it to the Contract Research Organization, along with the patient’s Adverse Events 
Log and Concomitant Medications Log within 24 hours of notification of the event.  The CRO must 
notify the Taro Pharmaceuticals U.S.A, Inc.’s Study Manager and Taro Pharmaceuticals U.S.A, Inc.’s 
Drug Safety Department within 24 hours of the initial notification of the event.  When appropriate, 
Taro Pharmaceuticals U.S.A, Inc.’s Drug Safety Department will notify the U.S. Food and Drug 
Administration (FDA) of drug related Serious Adverse Events. 
Documentation should be sent to Taro Pharmaceuticals U.S.A, Inc.’s Study Manager and/or Taro 
Pharmaceuticals U.S.A, Inc.’s Drug Safety Department listed below:

The Principal Investigator must provide a follow-up written report within 5 calendar days of reporting 
the event to the Medical Monitor. The written report must contain a full description of the event and 
any sequelae. Subjects who have had an SAE must be followed clinically until all parameters 
(including laboratory) have either returned to normal or are stabilized. The Investigator must also 
report follow-up information if it becomes known to the Investigator. Taro Pharmaceuticals U.S.A, 
Inc.’s Study Manager and/or Taro Pharmaceuticals U.S.A, Inc.’s Drug Safety Department must 
receive any follow-up within 24 hours of receipt by Medical Monitor.   
Reports of all SAEs must be communicated as soon as possible to the appropriate Institutional 
Review Board (IRB) or Independent Ethics Committee (IEC) and/or reported in accordance with local 
laws and regulations.

ETHICS  
This study will be conducted in accordance with the ethical principles that have their origin in the 
current Declaration of Helsinki and will be consistent with International Conference on Harmonization 
Good Clinical Practice (ICH GCP) and applicable regulatory requirements. The study will be 
conducted in compliance with the protocol. 
The rights, safety and well-being of the study Subjects are the most important considerations and 
should prevail over interests of society and science.   
 
11.1 
Informed Consent 
The Principal Investigator must ensure that Subjects and/or their legally acceptable representative (i.e., 
parent or guardian) are clearly and fully informed about the purpose, potential risks and other critical 
issues regarding clinical studies in which they volunteer to participate. The principles of Informed 
Consent/Assent, according to FDA Regulations and ICH GCP will be followed.  A copy of the proposed 
consent form and assent form must be submitted to the IRB, together with the protocol, for approval. Prior 

 
 
 
CONFIDENTIAL 
 
 
 
2 August 2016 
Protocol:  ADPS 1602

to beginning of the study, the Principal Investigator must have the IRB’s written approval of the written 
informed consent form, assent form, and any other information to be provided to Subjects. 
Informed consent/assent will be obtained from all Subjects using the following procedure: subjects who 
are 18 years of age or older must have provided IRB approved written informed consent. For subjects 
under the age an assent form for minors must be completed for subjects under the legal age of consent 
depending on age range required by state laws. Written assent must be accompanied by an IRB 
approved written informed consent from the Subject’s legally acceptable representative (i.e., parent or 
guardian). Prior to initiating screening for the study, Subjects will be given the approved ICF/assent 
describing the study and any risks associated with participation. The Subject will be allowed as much time 
as needed to read and understand the information presented in the consent/assent form. Appropriate 
study personnel will be available to answer any questions the Subject might have regarding the study or 
study-related procedures. If the Subject chooses to participate in the study, he or she will be asked to sign 
and date the consent/assent form and will be provided with a copy for his or her records. In addition, the 
Principal Investigator or the Principal Investigator’s Designee will provide a HIPAA authorization form (if 
applicable) for the Subject or the Subject’s legally acceptable representative (i.e., parent or guardian) to 
review and sign. Both the ICF/assent and the HIPAA authorization form (if applicable) must be signed by 
the Subject or the Subject’s legally acceptable representative (i.e., parent or guardian) before any 
protocol assessments can be undertaken. 
 
11.2 
Institutional Review Board  
Before study initiation, the Principal Investigator must have written and dated approval from the IRB 
for the protocol, consent form, Subject recruitment materials and any other written information to be 
provided to Subjects.  
Any changes to the protocol as well as a change of the Principal Investigator, which is approved by 
the Sponsor, must also be approved by the site’s IRB and documentation of this approval provided to 
the Sponsor/designee. Records of the IRB review and approval of all documents pertaining to this 
study must be kept on file by the Principal Investigator and are subject to inspection during or after 
completion of the study.  All SAEs must also be reported to the IRB. 
Periodic status reports must be submitted to the IRB at least annually, as well as notification of 
completion of the study and a final report within one (1) month of study completion or discontinuation. 
A copy of all reports submitted to the IRB must be sent to the Sponsor/designee. 
The Principal Investigator will ensure that an IRB that complies with the requirements set forth in 21 
CFR Part 56 will be responsible for the initial and continuing review and approval of the proposed 
clinical study. 
   
11.3 
Subject Confidentiality  
The monitor(s), the auditor(s), IRB/IEC, and the regulatory authority(ies), will be granted direct access 
to the Subject’s original medical records for verification of the clinical trial procedures and/or data, 
without violating the confidentiality, to the extent permitted by the applicable laws and regulations and 
that by signing a written informed consent form, the Subject or the Subject’s legally acceptable 
representative is authorizing such access. 
The identifying the Subject will be kept confidential and, to the extent permitted by the applicable laws 
and regulations, will not be made publicly available. If the results of the trial are published, the

12.2 
Maintenance and Retention of Records  
It is the responsibility of the Principal Investigator to maintain a comprehensive and centralized filing 
system of all relevant documentation. 
Copies of all pertinent records will be retained by the Principal Investigator for at least two years 
following final approval of the drug and/or notification from the Sponsor. These regulatory documents 
should be retained for a longer period if required by local regulatory authorities. These records 
include documents pertaining to the receipt and return of drug supplies, IRB, informed consent, 
source documents, as well as eCRFs (paper or electronic files). No documents shall be transferred 
from the site or destroyed without first notifying the Sponsor. If the Principal Investigator withdraws 
from the study, the records shall be transferred to a mutually agreed upon designee. Notice of such 
transfer will be given in writing to the Sponsor. 
The Principal Investigator is required to prepare and maintain adequate and accurate case histories 
designed to document all observations and other data pertinent to the investigation on each individual 
treated with the Investigational Product or entered as a control in the investigation. Data reported on 
the CRF, which are derived from source documents, must be consistent with the source documents.  
   
12.3 
Data Collection and Reporting  
Data for individual Subjects will be collected on eCRF designed by the Contract Research 
Organization. The data management system will be Electronic Data Capture (EDC). The Investigator 
and his/her study site personnel will be responsible for completing the eCRFs. The Investigator is 
required to verify that all of the requested information is accurately recorded in the eCRFs. All 
information requested in 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.  
[Redacted] 
The study monitor will be responsible for reviewing and verifying the data recorded in the eCRFs, 
utilizing the original source documentation and will query discrepant  findings. The Investigator and

eCRF sections may be monitored during these visits. At the end of the study, a closeout monitoring 
visit will be performed. Monitoring visits will be arranged in advance at a mutually acceptable time 
with site personnel. Sufficient time must be allowed by the site personnel for the monitoring of eCRFs 
and relevant source documents. The Study Coordinator and/or Principal Investigator should be 
available to answer questions or resolve data clarifications. Adequate time and space for these visits 
should be made available by the Principal Investigator. 
   
12.6 
Audits and Inspections  
During the course of the study and/or after it has been completed, one or more site visits may be 
undertaken by auditors as authorized representatives of the Sponsor. The purpose of the audit is to 
determine whether or not the study is being conducted and monitored in compliance with the protocol, 
recognized GCP guidelines and all applicable regulations. 
Additionally, the study may be inspected by regulatory agencies. These inspections may take place at 
any time during the course of the study and/or after it has been completed.  
THE INVESTIGATOR MUST NOTIFY THE CONTRACT RESEARCH ORGANIZATION and 
SPONSOR PROMPTLY OF ANY INSPECTIONS SCHEDULED BY REGULATORY AUTHORITIES, 
AND PROMPTLY FORWARD COPIES OF INSPECTION REPORTS TO THE SPONSOR. 
 
12.7 
Modifications to the Protocol  
The procedures defined in the protocol and in the eCRF will be carefully reviewed to ensure that all 
parties involved with the study fully understand the protocol. In order to ensure the validity of the data, 
no violations from the protocol, with minimal exceptions, may be made unless the issue is broad 
enough to warrant revision of the protocol. Such revisions must be submitted to and have 
documented approval from the Sponsor and the IRB prior to implementation. All amendments to the 
protocol, which involve substantial changes in study design, procedure or analyses, may be 
submitted to FDA for prior approval (if required).  
The only circumstance in which an amendment may be initiated without prior IRB approval is to 
eliminate apparent immediate hazards to a Subject or Subjects. However, the Principal Investigator 
must notify the Sponsor immediately and the IRB within 5 working days after implementation.  
All protocol violations will be reported on the protocol violation log and included in the study reports. A 
protocol violation is defined as any change, deviation, or departure from the study design or 
procedures of  research project that is NOT approved by the IRB prior to its initiation or 
implementation, OR deviation from standard operating procedures, Good Clinical Practices (GCPs), 
federal, state or local regulations. 
 
12.8 
Completion of Study  
The Principal Investigator is required to sign the eCRFs and forward all other relevant data and 
records to the Contract Research Organization.  
The Principal Investigator is expected to submit a final report to the IRB and the Sponsor within one 
(1) month of study completion or discontinuation.  CRO must submit a final report as agreed in the 
Study Agreement for this study between Sponsor and CRO.
