Synopsis 
 
Title: 
A Phase 3 Multi-Center, Double-Blind, Randomized, Vehicle-Controlled 
Study of S5G4T-1 in the Treatment of Papulopustular Rosacea 
Study Number: 
SGT-54-01 
Study Phase: 
3 
Indication: 
Papulopustular rosacea 
Study Period: 
12 weeks (84 Days) 
Study Products: 
1. S5G4T-1: Encapsulated Benzoyl Peroxide (E-BPO) Cream, 5%, 
developed by Sol-Gel Technologies and manufactured by 
 
, Montreal, Canada. 
2. S5G4T-2: Vehicle Cream, developed by Sol-Gel Technologies and 
manufactured by 
, Montreal, Canada. 
Study Objectives: To assess the efficacy and safety of S5G4T-1 compared to S5G4T-1 
Vehicle when applied once daily for 12 weeks in patients with 
papulopustular rosacea 
Study Design: 
In this Phase 3, double-blind, vehicle-controlled study, patients will be 
admitted into this multi-center, double-blind, randomized, vehicle-
controlled, parallel-group pivotal study only after a written informed 
consent has been obtained and after all inclusion/exclusion criteria have 
been met. Male and female patients at least 18 years of age with 
moderate or severe papulopustular rosacea [Investigator Global 
Assessment (IGA) grade 3 or 4] will be eligible for enrollment for daily 
treatment with S5G4T-1 or its vehicle for 12 weeks. 
Study 
Population: 
Approximately 350 male and female patients, at least 18 years of age, who 
meet the inclusion/exclusion criteria will be enrolled in the study. 
Investigational 
Sites 
It is estimated that up to 28 study centers in US will participate in this 
study. 
Dosing: 
Patients will be randomized in a 2:1 ratio to the study product or vehicle 
treatment group, respectively. Patients will apply the study product once 
daily for 12 weeks. Patients will use a “pea-size” amount for each area of 
the face (chin, left cheek, right cheek, nose, left forehead and right 
forehead). The study product will be spread as a thin layer in such a way 
as to provide an even distribution, avoiding the eyes, lips, inside the nose, 
mouth and all mucous membranes. Patients will receive detailed 
instructions on the method of application and quantity to use in order to 
assure that treatment is harmonized among all patients to best extent 
possible.

Synopsis 
 
Methodology: 
Clinical and Safety Evaluations will be performed at: 
1. Visit 1/Screening 
2. Visit 2/Baseline, Day 1 
3. Visit 3/Week 2, Day 15 (± 3 Days) 
4. Visit 4/Week 4, Day 29 (± 3 Days) 
5. Visit 5/Week 8, Day 57 (± 3 Days) 
6. Visit 6/Week 12, Day 85 (± 4 Days)/End of Treatment/End of 
Study) 
Patients will be admitted into the study after all inclusion/exclusion 
criteria have been met, including a clinical diagnosis of rosacea and after 
written informed consent has been obtained. Subjects with severe rosacea 
who are appropriate for systemic treatment need to be counseled regarding 
their treatment options by the Principal Investigator. 
At each visit, a 5-point IGA scale of rosacea; rosacea erythema, and 
telangiectasia; and inflammatory (papules, pustules) lesion counts will be 
performed and recorded. 
Safety will be assessed at all visits, and will include monitoring of local 
adverse experiences, Investigator Cutaneous Safety Assessment rating of 
dryness and scaling and Local Tolerability Assessment rating of itching 
and burning/stinging on a scale ranging from 0 (None) to 3 (Severe); 
patients will complete a Patient Reported Outcomes (PRO) questionnaire 
at Visit 2, 3, 4, 5 and 6 and Rosacea Quality of Life Questionnaire 
(RosaQoL) at Baseline and Visit 6 or at early termination.. 
Standardized photography of facial rosacea at Visit 2, 3, 4, 5 and 6 will be 
performed at select site(s). 
In addition to IGA, at each visit, the following safety measures will be 
recorded: monitoring for any AE including local and systemic; 
investigator Cutaneous Safety Assessment rating of erythema, dryness 
and scaling and Local Tolerability Assessments rating of itching and 
burning/stinging on a scale ranging from 0 (None) to 3 (Severe). 
Urine pregnancy tests will be performed on females of child-bearing 
potential at Screening, Baseline and every 4 weeks during study or at early 
termination. 
Regardless of the duration of the study, patients that exhibit serious 
adverse event (SAE), will be followed up until the SAE resolves, based 
on investigator’s medical judgment. 
Clinical Trial 
Duration 
Screening: -35 to 0 days prior to Baseline 
Duration of treatment: 12 weeks/84 days 
Patients have the right to stop the study for any reason at any given time.

Statistical 
Method: 
General Statistical Methods 
All statistical processing will be performed using SAS® version 9.3 or 
later unless otherwise stated. Statistical significance will be based on 
two-tailed tests of the null hypothesis resulting in p-values of 0.05 or less. 
Analysis Populations 
The intent-to-treat (ITT) population will consist of all randomized patients 
who were dispensed study product. The safety population will be 
comprised of all randomized patients who are presumed to have used the 
study product at least once and who provide at least one post-baseline 
safety evaluation. Patients will be considered per protocol (PP) if they 
complete the 12-week evaluation without noteworthy study protocol 
violations (i.e., any patient or investigator activity that could have possibly 
interfered with the therapeutic administration of the treatment or the 
precise evaluation of treatment efficacy). 
Patients 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 PP population. Data for these subjects will not be imputed by multiple 
imputation but rather their data will be imputed with values consistent 
with their status as treatment failures. 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 
Evaluations and Analyses 
Inflammatory lesion count will be recorded for each patient at Baseline 
and at Weeks 2, 4, 8 and 12. The absolute and percent change from 
baseline of inflammatory lesions will be derived for each patient at 
Weeks 2, 4, 8 and 12. 
The IGA will be recorded for each patient at Baseline, Weeks 2, 4, 8 and 
12. The IGA will be dichotomized into “success” and “failure” at 
Weeks 2, 4, 8 and 12 with a patient considered a success for those visits if 
the IGA is at least 2 grades less than baseline and are Clear or Almost 
Clear. 
The Rosacea erythema assessment, and telangiectasia assessment will be 
recorded at Baseline, Weeks 2, 4, 8 and 12. 
Patients will be asked to complete a Patient Reported Outcome, PRO 
questionnaire at Baseline, Weeks 2, 4, 8 and 12 and a Rosacea Quality of 
Life, RosaQoL questionnaire at Baseline and Week 12(or at the early 
termination visit). 
All assessments will be conducted for both ITT and PP.

Synopsis 
 
Statistical 
Method 
(continued): 
Statistical Hypothesis Testing 
Tests of superiority for the absolute change from Baseline in inflammatory 
lesions will be based on either parametric or non-parametric methods 
consistent with the statistical assumptions required to support the 
analyses. Specifically, the tests of superiority will be based on an 
ANCOVA with factors of treatment and analysis center and the respective 
Baseline lesion count as a covariate or on ranked data submitted to an 
ANCOVA with factors of treatment and analysis center and the respective 
Baseline lesion count as a covariate. If the treatment-by-analysis center 
interaction effect is significant at an alpha less than 0.10, then the effect 
will be included in the model; otherwise it will be removed. 
A skewness test, based on the methods presented by Zar 1984, will be 
applied to the residuals resulting from an ANCOVA. A two-sided p-value 
for the skewness test significant at 0.01 will imply the use of the non- 
parametric method. If a parametric analysis is indicated, the results of the 
parametric analysis will be considered the primary analysis. Should a 
non-parametric analysis be indicated, the absolute or percent changes in 
inflammatory lesions will be rank-transformed prior to submitting them to 
the ANCOVA. Results of the rank-transformed analyses then will be 
considered the primary analysis; however, results of the non- rank-
transformed analyses will also be presented. 
The IGA will be dichotomized into “success” and “failure” with a patient 
considered a success for those visits if the Investigator’s Global 
Assessment is at least 2 grades less than Baseline and “Clear” or “Almost 
Clear”. The analysis of the dichotomized IGA will be based on a logistic 
regression test with factors of treatment group and analysis center. 
Missing Efficacy Data Imputations 
Missing Week 12 data will be estimated by multiple imputation and 
subsequently analyzed. Missing lesion count data will be derived for the 
analysis using the method of Markov Chain Monte Carlo (MCMC) 
multiple imputation. The pattern of missing observations in each 
treatment group cannot influence the missing value estimation in the other 
because the imputation will be conducted independently for each 
treatment group. 
Safety 
Evaluation: 
Safety will be evaluated by tabulations of adverse events (AEs), 
Cutaneous Safety Assessments for dryness and scaling, assessments for 
scores (erythema and telangiectasia) and Patient Global Impression of 
Treatment Side-Effects (PGI-SE) will be presented with descriptive 
statistics at Baseline and at the scheduled study visits. Frequencies and 
percentages for each outcome category will be included in these statistics.

INTRODUCTION AND BACKGROUND 
S5G4T-1 is an innovative topical formulation containing 5% encapsulated benzoyl peroxide (E-
BPO) that Sol-Gel is developing for the treatment of rosacea. If approved, S5G4T-1 will be the 
first product containing E-BPO for the treatment of rosacea. Sol-Gel believes S5G4T-1 has the 
potential to be as tolerable as, and more effective than, currently marketed rosacea drugs. 
Rosacea is a chronic and recurrent inflammatory dermatological disorder of unknown etiology. 
The disease is common, especially in fair-skinned people of Celtic and northern European heritage. 
The onset of the disorder is usually between the ages of 30 and 50. Early stages of the disease 
affect women more often than men at a ratio of 3 to 1 (Jansen and Plewig 1997 and 
McDonnell and Tomecki 2000). Rosacea usually starts as flushing and subtle redness on the 
cheeks, nose, chin or forehead. Alcohol, hot drinks, spicy foods, stress, sunlight and extreme heat 
or cold can trigger the onset of this disease. If left untreated, rosacea can slowly worsen over time. 
As the condition progresses, patients experience inflammatory lesions (papules and pustules), 
vivid erythema and telangiectasia. Patients may develop furuncles, cystic nodules, granulomas 
and tissue hypertrophy, sometimes leading to rhinophyma. 
The first report on the treatment of rosacea with benzoyl peroxide as a single agent was described 
by in Montes et al. in 1983. In this limited study, 5% benzoyl peroxide, after 5 to 8 weeks of 
treatment, demonstrated superiority compared to control with respect to papules, pustules and 
erythema but not telangiectasia. The formulation was a basic formulation with benzoyl peroxide 
dissolved and delivered in acetone. Irritation and burning was reported in both groups, most likely 
due to the well-known effects of benzoyl peroxide. 
More recently, Breneman et al. 2004 published the results of a study in collaboration with 
J. Leyden. This study was a double-blind, vehicle-controlled study, using a combination gel 
product of 5% benzoyl peroxide and 1% clindamycin to treat patients having moderate to severe 
rosacea. The most dramatic effect of the benzoyl peroxide/clindamycin treatment was on the 
reduction of papules and pustules. Side effects included the well-known effects of benzoyl 
peroxide, burning and itching. 
Yamasaki et al. published a paper in 2007 which may explain why benzoyl peroxide potentially 
has a therapeutic benefit in the treatment of rosacea. The team reported that a protease that splits 
the antimicrobial peptide, cathelicidin, from its protein precursor is elevated in inflammatory 
rosacea. Cathelicidin subsequently induces the formation of the pro-inflammatory cytokine IL-8. 
It has also been previously reported that Propionibacterium acnes induces elevated levels of 
cathelicidin in the skin. These observations support the hypothesis that P. acnes has a major role 
in the etiology of rosacea, and provide a mechanistic understanding of why benzoyl peroxide may 
have a therapeutic benefit in the treatment of rosacea. 
Rosacea is treated with both systemic and topical therapies. However, topical therapies are 
preferable because of side effects caused by the use of systemic therapies. 
According to the U.S. National Rosacea Society, approximately 16 million people in the United 
States are affected by rosacea. According to a study commissioned by the Sponsor, approximately 
4.8 million people in the United States experience subtype II symptoms and physicians estimate 
that only 20% of the U.S. rosacea population is treated. The topical drugs approved by the FDA 
to treat subtype II rosacea generated aggregate revenues of approximately $392 million in the 
United States for the 12 months period ending June 30, 2017.

OVERALL STUDY DESIGN 
This study will be a randomized, double-blind, multicenter, parallel group, active- and vehicle-
controlled pivotal study of the efficacy, and safety of S5G4T-1 and its vehicle for the treatment 
of papulopustular rosacea for 12 weeks. Approximately 350 patients with moderate to severe 
rosacea (rated 3 or 4 on the 5-point IGA scale) will be enrolled at up to 28 sites. Patients in this 
randomized, double-blind, vehicle-controlled, parallel-group multi-center study will be randomly 
assigned in a 2:1 ratio to S5G4T-1 or vehicle, respectively. Subjects with severe rosacea who are 
appropriate for systemic treatment need to be counseled regarding their treatment options by the 
Principal Investigator. 
Patients will receive once daily treatment with S5G4T-1 or vehicle cream for 12 weeks. After the 
screening period, qualified patients will be randomly assigned at the Baseline visit and treated for 
12 weeks. Efficacy assessments will include facial inflammatory lesion counts and IGA 
assessment ranging from 0 (Clear) to 4 (Severe). Investigators will be provided with instructions 
for lesion counts to ensure consistency of procedure. Patient reported outcomes (PRO) will be 
assessed with the PAPSS (Patient Assessment of Papulopustular rosacea Signs and Symptoms), 
PAPI (Patient Assessment of Papulopustular rosacea Impacts) and PGI-S (Patient Global 
Impression of Symptom Severity) that will be administered at Baseline, Weeks 2, 4, 8 and 12, or 
at early termination. In addition, the PGI-C (Patient Global Impression of Change), PGI-TS 
(Patient Global Impression of Treatments Satisfaction) and PGI-SE (Patient Global Impression of 
Treatments Side Effects) will be administered at Weeks 2, 4, 8 and 12, or at early termination 
[FDA Guidance 2009]. Rosacea Quality of Life (RosaQoL) questionnaire will be administered at 
Baseline, and Week 12, or at early termination. Safety will be assessed at all visits and will include 
monitoring local and systemic adverse events (AEs); the investigator Cutaneous Safety 
Assessment rating of erythema, dryness and scaling and Local Tolerability Assessments rating of 
itching and burning/stinging on a scale ranging from 0 (None) to 3 (Severe). 
Patients will return to centers for IGA, lesion counts, PRO questionnaire, , Investigator Cutaneous 
Safety Assessment and Local Tolerability Assessments at Weeks 2, 4, 8 and 12. At Week 12 (or 
at the early termination visit) patients will be asked to complete RosaQoL questionnaire. Adverse 
events and concomitant medications will be assessed throughout the treatment period. A urine 
pregnancy test is required at Visit 1, 2, 4, 5 and 6 for all females of child-bearing potential. 
Clinical Evaluations will be performed at: 
• Visit 1/Screening 
• Visit 2/Baseline, Day 1 
• Visit 3/Week 2, Day 15 (± 3 Days) 
• Visit 4/Week 4, Day 29 (± 3 Days) 
• Visit 5/Week 8, Day 57 (± 3 Days) 
• Visit 6/Week 12, Day 85 (± 4 Days)/End of Treatment)

STUDY POPULATION 
12.1. 
Randomization and Blinding 
It is planned that approximately 350 patients who meet the inclusion/exclusion criteria will be 
enrolled in this study at up to 28 U.S. study sites. Patients will be at least 18 years of age and 
older, of either gender. Efforts will be made to enroll patients ages matching the target study 
population. 
The study product will be administered in a double-blinded fashion, i.e., the treatment assignment 
will not be known to the patient, to study personnel, or Sol-Gel and its representatives. Patients 
will be instructed not to discuss the study product with the study personnel. Patients will be 
randomly assigned in a 2:1 ratio as follows: 
• E-BPO Cream, 5% (S5G4T-1) (234 patients) 
• Vehicle Cream (S5G4T-2) (117 patients) 
Each patient who signs an informed consent, meets inclusion/exclusion criteria, and successfully 
completes the screening procedures, will be enrolled in the study. The patient randomization 
schedule will be a permuted block design stratified by investigational site. Blocks will be 
composed of 3 treatment assignments in a ratio of 2:1 study product and vehicle, respectively. 
Complete blocks from the randomization schedule will be allocated to investigational sites as they 
randomize patients to maintain the randomization ratio of 2:1 study product and vehicle, 
respectively. 
Additionally, the staff involved in data management and statistical evaluation will remain blinded 
until identification of the per protocol population is finished and a database lock memo is issued. 
The randomization schedule and treatment code will not be revealed to the patients, study 
personnel, Sol-Gel or its representatives until after the database lock, except to the Medical 
Monitor or Principal Investigator for an emergency. Access to the randomization list will be 
maintained by and limited to the unblinded Biostatistician and the designated personnel directly 
responsible for labeling of study materials. The Medical Monitor will not have access to the 
randomization list, but may determine that unblinding one or all patients may be necessary in the 
case that the safety of study patients is at risk. In an emergency, the study blind may be broken 
only if: 
• In the opinion of the Medical Monitor and/or the PI, it is in the patient's best interest to do 
so 
• Knowledge of the treatment will alter the clinical management of the patient 
In the case of an emergency that requires unblinding, the Investigator can request to unblind the 
patient without prior contact with the Medical Monitor although follow-up between the 
Investigator and Medical Monitor must occur so that all parties are aware of the unblinding. 
Although it is recommended that the Investigator contact the Medical Monitor prior to unblinding 
any patient, in instances where this is not feasible or advisable the PI may directly access the 
patient's treatment assignment. In all situations, the Interactive Web Response System (IWRS) 
will be used to obtain treatment assignment information with limited access to only the above-
designated individuals, and any unblinding will be documented as a protocol deviation.

STUDY PROCEDURES 
13.1. 
Study Patient Identification 
When the patient signs the informed consent, he/she will be assigned a three (3)-digit patient 
number. The complete patient ID will consist of the 3-digit site number followed by the 3-digit 
patient number: e.g., 
 (first patient screened at site 
). This number will remain with the 
patient for the duration of the study and will not be reassigned to another patient should the patient 
screen fail. 
13.2. 
Screen Failure and Discontinuation Criteria 
A screen failure is a patient who is not randomized/enrolled in the study due to ineligibility, after 
signing an Informed Consent Form, and would not have received study product. The Informed 
Consent Form signed by the patient should be kept with the source document for patients who do 
not pass the screening procedures. The documentation should include identification of the 
eligibility criterion or criteria that were and were not met. The patient should not be re-screened 
for this study without Sol-Gel’s approval. 
Although encouraged to complete the study whenever possible, patients are free to discontinue 
their participation in this study at any time and for any reason without prejudice. A patient may 
be withdrawn from the study prior to study completion for any of the following reasons: 
• Investigator opinion that it is not in the patient’s best interest to continue. 
• Patient Request /Withdraw Consent – Whenever the patient decides it is in his/her best 
interest to withdraw. 
• Lack of Efficacy/ Worsening of Condition. 
• Adverse Event – when the investigator thinks it’s in the patient’s best interest 
• Lost to Follow-up – Documentation confirmed at minimum by two phone calls and 
certified letter. Every effort should be made to capture an explanation for the lost-to follow- 
up event. 
• Protocol Violation – When requirements of the protocol are not respected, especially when 
patient safety is concerned. 
• Pregnancy. 
• Unblinding of study product. 
Study staff should make efforts to encourage patients to complete the study on time. If a patient 
prematurely withdraws during the study, every effort should be made to complete at least the 
Week 12/End of Study assessments. 
In the case of patients who discontinue due to an Adverse Event, the Investigator will conduct 
follow-up contacts with the patient until the Investigator, Sponsor and Medical Monitor agree the 
event is satisfactorily resolved and/or stabilized. 
Patients discontinued early from the study shall not be replaced. 

SGT-54-01, Ver 4.0 
CONFIDENTIAL 
Page 39 of 85 
 
 
13.3. 
Patient Screening and Enrollment 
The study personnel will review the IRB approved informed consent form with each patient and 
give the patient an opportunity to have all questions answered before proceeding. The consent 
form must be signed by each patient before the patient is enrolled into the study. A copy of the 
signed consent will be given to every patient (or legally authorized representative) and the original 
will be maintained with the patients’ records. 
Patients that require a wash-out of more than 30 days from their initial informed consent/assent 
signing must be re-consented before any further study procedures can begin. 
13.4. 
Assignment of Randomization 
The patient randomization schedule will be a permuted block design stratified by investigational 
site. Blocks will be composed of 3 treatment assignments in a ratio of 2:1 study product and 
vehicle, respectively. Complete blocks from the randomization schedule will be allocated to 
investigational sites as they randomize patients. Patients will be randomized through the IWRS 
and assigned a unique randomization ID indicating treatment group. The study product supplies 
will be packed in 4 pumps per kit and will be numbered in a scrambled randomized method. The 
kits will be dispensed by the IWRS according to the randomized treatment group. 
The first supplied pump in each kit is marked A (e.g. number of pump within a kit is XXXXA), at 
Visit 4/ Week 4 the patient will return the pump and will be dispensed with the next pump which 
is marked B. At Visit 5/ Week 8, the patient will return the pump and will be dispensed with a 
pump marked C. Pump marked as D may be dispensed to patients who lost/damaged/ran-out of 
study product. 
13.5. 
Demographics/Medical   History 
A demographic profile and complete medical history will be recorded prior to starting study 
product. The medical history will include a complete review of all current diseases and their 
respective treatments. 
13.6. 
Concomitant   Medications 
Concomitant medications and any medications taken in the 30 days prior to signing informed 
consent will be recorded as prior/concomitant medications (using their 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 either a 
regular or “prn” basis, including vitamins, aspirin and acetaminophen, should be recorded on this 
page prior to commencing the use of the study product. 
13.7. 
Physical Examination 
The investigator, sub-investigator or appropriately delegated and qualified designee will perform 
a brief physical examination, prior to the patient starting study product. The exam will include 
heart, lung, abdomen evaluation as well as recording height, weight and vital signs. Vital signs 
are to include sitting blood pressure, oral temperature, heart rate and respiratory rate.

13.8. 
Urine Pregnancy Test 
Females of childbearing potential (excluding women who are surgically sterilized or post-
menopausal for at least 2 years), in addition to having a negative urine pregnancy test, must be 
willing to use an acceptable form of birth control during the study. An investigator could repeat the 
pregnancy test at any time during the study if there is any suspicion or possibility that the patient 
is pregnant. Urine pregnancy test will also be conducted starting at Visit 1/Screening and at each 
visit [Baseline, Weeks 2, 4, 8 and 12 (End of Study)]. For the purpose of this study, the 
following are considered acceptable methods of birth control: intrauterine device (IUD); 
hormonal (injections, implants, transdermal patch, vaginal ring); abstinence; oral contraceptives; 
female condom; diaphragm with spermicides; cervical cap with spermicides; contraceptive 
sponge. 
Patients entering the trial that are on hormonal contraceptives must have been on this method for 
at least 3 months (90 days) prior to the trial and continue the method for the duration of the trial. 
Patients who had used hormonal contraception and stopped must have stopped no less than 3 
months prior to Baseline. Patients entering the study who had an Essure procedure must have had 
this procedure at least 3 months prior to the study and have undergone an Essure confirmation test 
to ensure its efficacy. A sterile sexual partner is not considered an adequate form of birth control.

CLINICAL OUTCOME ASSESSMENTS 
The determination of efficacy will be based on investigator evaluations of the signs and symptoms 
of rosacea. Evaluators must be a physician or have appropriate documented experience and 
training. Every effort will be made to ensure appropriate training is provided to the investigators 
for consistent diagnosis and evaluation of rosacea. 
For consistency of evaluations, the same designated evaluator who performs the Baseline 
assessments shall perform the assessments at Visit 6/Week 12; when this becomes impossible, 
another delegated evaluator may perform the assessments. 
14.1. 
Investigator Global Assessment (IGA) 
The Investigator Global Assessment (IGA) will be performed at Screening/Baseline, Weeks 2, 4, 
8 and 12 (End of Study) visits. 
Patients are eligible for enrollment if they have facial rosacea with a global severity of a 3 
(moderate) or a 4 (severe) on the IGA scale. 
The IGA scale provided in Table 1 will be used to describe the severity grade and subsequent 
score:

Patient Reported Outcomes (PRO) 
There are six PRO questionnaires to be administered in the study and each is summarized below. 
Each will be administered to all patients during the designated study visits with instruction from 
the Study Staff that they be completed: 
• Only by the patient without amendment or interpretation of the patient’s response by a 
clinician or anyone else. 
• Prior to any other assessments or procedures. 
In the event the patient skips any questionnaire items; the Study Staff will ask the patient to 
complete the form. The PRO questionnaire data will be entered into EDC, and a copy will be 
placed with the patient source at the site according to the ICH-GCP guideline (4.9.5). 
The PAPSS (Appendix 2): The PAPSS is a 4-item questionnaire that asks patients to assess the 
severity of their rosacea symptoms (burning, itching, redness, and bumps) in the 24 hours prior to 
assessment on an 11-point numeric rating scale (NRS) ranging from “0=none” to “10=worst 
possible symptom”. The questionnaire can be completed in less than one minute and is 
administered via pen-and-paper at the Baseline visit and site visits at Weeks 2, 4, 8 and 12 (End 
of Study) or early termination. Items can be scored individually as well as together to form a total 
score. In the present context, within visit scores from Items 1 (burning), 2 (itching), and 4 (bumps) 
are summed and averaged to create a total score that will be used to evaluate efficacy hypotheses. 
The PAPI (Appendix 3): The PAPI is a 3-item questionnaire that asks patients to assess the 
papulopustular rosacea related embarrassment, self-consciousness, and frustration in the 7 days 
prior to assessment on an 11-point NRS ranging from 0 [“not (concept) at all”] to 10 [“extremely 
(concept)”]. The questionnaire can be completed in less than one minute and is administered via 
pen-and-paper at the Baseline visit and site visits at Weeks 2, 4, 8 and 12 (End of Study) or early 
termination. Items can be scored individually as well as together to form a total score. 
PGI-S (Appendix 4): The PGI-S is a single item questionnaire that asks respondents to describe 
the severity of their rosacea symptoms “right now” (i.e., at the present moment) on a five-point 
verbal response scale ranging from “Clear” (face is clear, no redness) to “Severe” (face has 
numerous small and/or large bumps, severe redness). Patients are encouraged to look in a mirror 
to help with their response and the questionnaire can be completed in less than 30 seconds. The 
PGI-S is administered via pen-and-paper at the Baseline visit and site visits at Weeks 2, 4, 8 and 
12 (End of Study) or early termination. Though data generated from the PGI-C can be supportive 
of efficacy hypotheses, the primary purpose of the tool is to support anchor-based analyses that 
will inform how researchers may interpret the meaning of change in the primary and secondary 
assessments. 

SGT-54-01, Ver 4.0 
CONFIDENTIAL 
Page 49 of 85 
 
 
PGI-C (Appendix 5): The PGI-C is a single item questionnaire that asks respondents to describe 
the change they have noticed in their rosacea symptoms since the start of the study a 7-point VRS 
ranging from “Very much improved” to “Very much worse”. Patients are encouraged to look in a 
mirror to help with their response and the questionnaire can be completed in less than 30 seconds. 
The PGI-C is administered via pen-and-paper at the site visits at Weeks 2, 4, 8 and 12 (End of 
Study) or early termination. Though data generated from the PGI-C can be supportive of efficacy 
hypotheses, its primary purpose is to support anchor-based analyses that will inform how 
researchers may interpret the meaning of change in the primary and secondary assessments. 
PGI-TS (Appendix 6): The PGI-TS is a single item questionnaire that asks respondents to describe 
how satisfied they are “right now” with the rosacea treatment administered as part of the study on 
a 5-point VRS ranging from “I am very satisfied” to “I am very dissatisfied”. The questionnaire 
can be completed in less than 30 seconds and is administered via pen-and-paper at the site visits 
at Weeks 2, 4, 8 and 12 (End of Study) or early termination. Though data generated from the 
PGI-TS can be used for other purposes, its primary purpose is to support anchor-based analyses 
that will inform how researchers may interpret the meaning of change in the primary and secondary 
assessments. 
PGI-SE (Appendix 7): The PGI-SE is a single item questionnaire that asks respondents to describe 
how bothered they are “right now” with the rosacea treatment administered as part of the study on 
a 5-point VRS ranging from “I am not bothered” to “I am extremely bothered”. The questionnaire 
can be completed in less than 30 seconds and is administered via pen-and-paper at the site visits 
at Weeks 2, 4, 8 and 12 (End of Study) or early termination. Though data generated from the 
PGI-TSE can be used for other purposes, its primary purpose is to support anchor-based analyses 
that will inform how researchers may interpret the meaning of change in the primary and secondary 
assessments. 
14.6. 
Rosacea Quality of Life (RosaQoL) 
There is a symptom subscale with seven questions (items 2, 6, 9, 16, 17, 18 and 19 in Appendix 
8) , a functional subscale with 3 questions (items 13, 15 and 21 in Appendix 8) and an emotion 
subscale with 11 questions (items 1, 3, 4, 5, 7, 8, 10, 11 12, 14 and 20 in Appendix 8) to be 
administered in the study. The questionnaire will be administered to all patients during the 
designated study visits with the appropriate instructions from the Study Staff. The questionnaire 
should be completed: 
• Only by the patient without amendment or interpretation of the patient’s response by a 
clinician or anyone else. 
• After completion of the Patient Reported Outcomes (PRO) questionnaires 
In the event the patient skips any questionnaire items; the Study Staff will ask the patient to 
complete the form. The QoL questionnaire data will be entered into the EDC system by the Study 
Staff, and a copy will be placed with the patient source documents at the site according to the 
ICH-GCP guideline (4.9.5). 
All items should be scored for the following answers: 
• Never: 1 
• Rarely: 2 
• Sometimes: 3 

SGT-54-01, Ver 4.0

Page 50 of 85 
 
 
• Often: 4 
• All the time: 5 
 
The Site Staff and anyone else provided with a copy of the RosaQoL instrument for the purpose 
of the study will be instructed that the RosaQoL instrument is protected by Common Law 
copyright. No part of this may be reproduced or transmitted in any form or by any means, now 
known or to be invented or adapted, for purpose of financial gain or profit. 
An overall total score will be calculated; this score will be the unweighted mean of all RosaQoL 
questions. In addition to the total score, each subscale (symptom, functional and emotion) will 
also have a score calculated; these scores will the unweighted mean of the group of questions that 
comprise the subscale. Further details on the handling of missing responses and calculation of the 
subscale scores will be detailed in the Statistical Analysis Plan (SAP).

as soon as possible.  The overseeing IRB should also be notified. 
17.2. 
Definitions 
An adverse event (AE) is defined as any untoward medical occurrence in a patient 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 this medicinal product. 
A serious adverse event (SAE) is an adverse event that results in any of the following outcomes: 
• Death 
• Life-threatening event (i.e., the patient was, in the opinion of the investigator, at immediate 
risk of death from the event as it occurred. It does not include an event that, had it occurred 
in a more severe form, might have caused death) 
• Requires in-patient hospitalization or prolongs hospitalization 
• A persistent or significant disability/incapacity or substantial disruption of the ability to 
conduct normal life functions 
• Congenital anomaly/birth defect 
• Other adverse events that may be considered serious based upon appropriate medical 
judgment, may jeopardize the patient and may require medical or surgical intervention to 
prevent one of the outcomes listed above. 
Immediately Reportable Adverse Events (IRAE) is any serious AE or any AE that necessitates 
discontinuation of study product, including pregnancy. 
Unexpected Adverse Event is any adverse drug experience, the specificity or severity of which is 
not consistent with the current approved product labeling (package insert) for the study product, 
the Investigator’s Brochure, or as described in the clinical protocol and consent materials. 
Intensity of Adverse Events are the maximum intensity of an AE during a day should be recorded 
on the eCRF. If the intensity of an AE changes over a number of days, then separate entries should 
be made having distinct onset dates for the changes in severity. 
• Mild - AEs are usually transient, requiring no special treatment, and do not interfere with 
patient’s daily activities. 
• Moderate - AEs typically introduce a low level of inconvenience or concern to the patient 
and may interfere with daily activities, but are usually ameliorated by simple therapeutic 
measures. 
• Severe - AEs interrupt a patient’s usual daily activity and traditionally require systemic 
drug therapy or other treatment.

17.3. 
Causal Relationship to Study product 
The following criteria should be used in assessing the apparent causal relationship of an AE to 
study product: 
Definitely - The AE: 
• follows a reasonable temporal sequence from study product administration 
• abates upon discontinuation of the study product (de-challenge) 
• is confirmed by reappearance of the reaction on repeat exposure 
Probably - The AE: 
• follows a reasonable temporal sequence from study product administration 
• abates upon discontinuation of the study product (de-challenge). 
• cannot be reasonably explained by the known characteristics of the patient’s state. 
Possible - The AE: 
• follows a reasonable temporal sequence from study product administration 
• but that could readily be produced by a number of other factors. 
Unlikely - The AE: 
• follows a reasonable temporal sequence from study product administration. 
• could have been produced by either the patient’s clinical state or by study product 
administration. 
Not related - The AE: 
• does not have a reasonable temporal association with the administration of study product 
• has some other obvious explanation for the event. 
17.4. 
Eliciting and Reporting of Adverse Events 
The investigator will periodically assess patients for the occurrence of adverse events. In order to 
avoid bias in eliciting adverse events, the patient or parent/legally authorized representative should 
be asked a non-specific question (e.g., “How have you been feeling since your last visit?”) to assess 
whether any AE has been experienced since the last visit. All adverse events (as defined in 
Section 17.2), either observed by the Investigator or one of his/her medical collaborators, or 
reported by the patient spontaneously, or in response to direct questioning, will be reported and 
documented in the source and the study reporting forms. When reporting an adverse event, the 
Investigator must assign a severity grade to each event and declare an opinion on the relatedness 
of the event to the study product or procedure. Serious or unexpected adverse events must be 
reported to the CRO within 24 hours of when the Investigator first learns of the occurrence of the 
event. 
Adverse events will be documented in the source document and recorded in a timely manner on 
case report forms. Adverse events that are identified at the last assessment visit (or the Early 
Termination Visit) must be recorded on the AE eCRF with the status of the AE noted. 

SGT-54-01, Ver 4.0 
CONFIDENTIAL 
Page 56 of 85 
 
 
Adverse event reporting begins from the signing of informed consent/assent. Study product-
related adverse events should be followed until resolved or 30 days after the final study 
treatment. Regardless the duration of the study, patients that exhibit serious adverse event (SAE), 
will be followed up until the SAE resolves, based on investigator’s medical judgment or are 
considered to be chronic (stabilized for at least 30 days). All events that are ongoing at this time 
will be recorded as ongoing on the eCRF. 
17.5. 
Expedited Reporting Responsibilities of the Study Center 
For any serious or unexpected adverse event, the Sponsor or its designee must be notified within 
24 hours of when the Investigator first learns of the occurrence of the event. Expedited reporting 
requirements for serious adverse events are described below. Adequate information must be 
collected with supporting documentation to complete a standard report for submission to Sol-Gel. 
The adverse event term on the AE eCRF and the SAE report should agree exactly. Special 
attention should be given to recording hospitalizations and concomitant medications. 
Patients with unresolved study or product-related adverse event(s) or serious adverse event(s) 
should be followed by the investigator until the events are resolved, events determined to be 
chronic or the patient is lost to follow-up. Resolution means the patient has returned to the Baseline 
state of health, or the investigator does not expect any further improvement or worsening of the 
adverse event. The investigator should continue to report any significant follow-up information 
to the sponsor up to the point that the event has resolved. Any serious adverse event reported by 
the patient to the investigator that occurs within 30 days after the last assessment, and are 
determined by the investigator to be reasonably associated with the use of the study product, should 
be reported to the sponsor within 24 hours of when the Investigator first learns of the occurrence 
of the event. 
When reporting a serious adverse event (SAE) the Investigator (or the Study Coordinator) will 
promptly report any serious adverse event or pregnancy to the Sponsor or its designee by telephone 
email, immediately after the investigator becomes aware of the event. An SAE form should be 
completed and sent by fax, email, or overnight courier to the Sponsor or its designee within 24 
hours of knowledge of the event by the site. In many cases, only preliminary information will be 
available. Appropriate follow up information should be sought (hospital discharge summaries, 
operative reports etc.) and a follow up SAE report form submitted. A designation of causality 
from the study product should always be included with a follow up report. Assess and report the 
causality of the event. 
17.6. 
Submitting an Expedited Safety Report to the IRB 
Once all supporting documentation is received for the reported event, the Medical Monitor, in 
conjunction with Sol-Gel, will determine if the safety report is eligible for expedited review. When 
expedited safety reporting to regulatory authorities is indeed required, the Investigator should 
review and update any newly available materials at once. Follow-up queries may be sent to the 
study center to further clarify the event. 

SGT-54-01, Ver 4.0 
CONFIDENTIAL 
Page 57 of 85 
 
 
The Sponsor, or its designee, is responsible for submitting reports of serious, unexpected related 
AEs to regulatory authorities on an expedited basis, according to the ICH E2A Guideline and to 
other regulatory authorities according to national and local regulations as required. The Sponsor, 
or its designee, is responsible for prompt submission to the IRB or EC of any expedited SAE 
reports submitted to regulatory authorities. All investigators participating in ongoing clinical 
studies will receive copies of the SAE reports submitted on an expedited basis to regulatory 
authorities 
17.7. 
SAE & AEs Requiring Discontinuation of Study Drug, including Pregnancies 
ANY SAE, WHICH OCCURS AFTER A PATIENT HAS ENTERED THE STUDY, WHETHER 
OR NOT RELATED TO STUDY PRODUCT, MUST BE REPORTED TO THE SPONSOR OR 
ITS DESIGNEE IMMEDIATELY (WITHIN 24 HOURS) VIA TELEPHONE, EMAIL OR 
FACSIMILE. IF INITIALLY REPORTED VIA TELEPHONE, THIS MUST BE FOLLOWED-
UP BY A FACSIMILE OR EMAIL OF THE WRITTEN SAE REPORT WITHIN 24 HOURS 
OF THE CALL TO THE SPONSOR OR ITS DESIGNEE. 
Non-serious events that require discontinuation of study product (including laboratory 
abnormalities) should be reported to the Sponsor or its designee immediately and within 1 working 
day. 
Patients who discontinue due to experiencing study product-related adverse events should be 
followed clinically until their health has returned to baseline status, or until all parameters have 
returned to normal. It is expected that the investigator will provide or arrange appropriate 
supportive care for the patient. 
A patient who experiences a severe adverse event related to study product will be discontinued 
from the study, but, regardless of the duration of the study, patients that exhibit serious adverse 
event (SAE), will be followed up until the SAE resolves, based on investigator’s medical judgment 
or are considered to be chronic (stabilized for at least 30 days). For safety reporting instructions 
see SAE and Pregnancy Form Report Instructions. 
17.8. 
Pregnancy 
At the time, Principal Investigator or site personnel becomes aware that a study patient became 
pregnant following study participation, the Principal Investigator or designee will report the 
pregnancy immediately by phone and/or by faxing a completed Pregnancy Report to the Sponsor 
or its designee within one working day of being notified of the pregnancy report. 
The report will include the following elements: 
• Patient (mother’s) coded study identifier; 
• Date of patient’s last menstrual period; 
• Total accumulated dose of study treatment administered to date; 
• Date of study product administration. 
The investigator will follow the patient until completion of the pregnancy and must assess the 
outcome in the shortest possible time but not more than 30 days within completion of the 
pregnancy. 

SGT-54-01, Ver 4.0 
CONFIDENTIAL 
Page 58 of 85 
 
 
Upon delivery, miscarriage or abortion, the Principal Investigator or designee must forward a 
follow-up Pregnancy Report with any relevant information on the present condition of the fetus to 
the Sponsor or its designee, including: 
• Mother’s coded study identifier(s); 
• Gestational age at delivery, miscarriage or abortion; 
• Birth weight, gender, length and head circumference, if available; 
• Apgar scores recorded after birth, if available; 
• Any abnormalities. 
If the outcome of the pregnancy meets the criteria for immediate classification of an SAE (e.g., 
spontaneous or therapeutic abortion [any congenital anomaly detected in an aborted fetus is to be 
documented], stillbirth, neonatal death, or congenital anomaly), the investigator will report the 
event by phone and by faxing a completed SAE report form to the Sponsor or its designee within 
one working day of being notified of the pregnancy report. 
If the trial is completed before the outcome of the pregnancy is known, the Sponsor or its designee 
will assume the responsibility for following up on the pregnancy. The Sponsor or its designee will 
contact the Investigator or Study coordinator on or around the potential expected date of delivery 
to follow-up on the outcome of pregnancy and will also check on the status of the infant 8 weeks 
post-delivery. Upon awareness of the pregnancy outcome and known status of the infant following 
8 weeks of delivery, the investigator will complete the applicable pregnancy report forms and fax 
to the Sponsor or its designee within 1 day of being notified. 
17.9. 
Post Study Adverse Events 
17.9.1. 
Non-serious Adverse Events 
Adverse events that are identified at the last assessment visit (or the Early Termination Visit) must 
be recorded on the AE eCRF with the status of the AE noted. 
17.9.2. 
Serious Adverse Events 
Serious adverse events that are identified on the last assessment visit (or the Early Termination 
Visit) must be recorded on the AE eCRF page and reported to Sol-Gel according to the procedures 
outlined above. Patients with unresolved previously reported serious adverse events, or any new 
serious adverse events identified on the last assessment visit, should be followed by the 
investigator until the events are resolved, or the patient is lost to follow-up. Resolution means the 
patient has returned to the baseline state of health, or the investigator does not expect any further 
improvement or worsening of the adverse event. The investigator should continue to report any 
significant follow-up information to Sol-Gel up to the point that the event has resolved. Any 
serious adverse event reported by the patient to the investigator that occurs after the last 
assessment, and are determined by the investigator to be reasonably associated with the use of the 
study product, should be reported to Sol-Gel.

STUDY PRODUCTS / CLINICAL SUPPLIES 
18.1. 
Method of Treatment Assignment 
Patients who satisfy all the inclusion and none of the exclusion criteria will be randomized to one 
of two treatment arms. Randomization will be performed in the IWRS according to a computer-
generated randomization schedule. The randomization schedule will be generated by the 
unblinded statistician and uploaded to the IWRS. The randomization schedule will be maintained 
securely within the IWRS. Patients will be randomized to Encapsulated Benzoyl Peroxide 
Cream, 5%, or Vehicle Cream, once daily on a 2:1 basis for twelve (12) weeks. 
Once a patient is determined eligible for the study at the Baseline visit, the patient will be 
randomized to study product assignment by the IWRS. Each study product carton will contain 
four pumps of the same product; The first supplied pump in each kit is marked A (e.g. number of 
pump within a kit is XXXXA), at Visit 4/ Week 4 the patient will return the pump and will be 
dispensed with the next pump which is marked B. At Visit 5/ Week 8, the patient will be dispensed 
with a pump marked C. The pump marked as D is a backup pump. The patient number will be 
added to both parts of the kit label (open part and tear-off label and to the pump label).

Preparation, Dispensing and Storage Instructions 
The study product must be dispensed only to study patients and only at study sites specified on the 
form FDA 1572 by authorized personnel as required by applicable regulations and guidelines. 
Study product will be dispensed at: Baseline, Weeks 4 and 8. Study product will be returned at: 
Weeks 4, 8 and 12. Study product weight will be documented in EDC prior to dispensing and after 
return of each pump per flow chart (Section 13.9 and Section 5.2). 
Each Patient will be instructed on the importance of returning his or her study product at each 
designated visit. If a Patient does not return his or her study product, he or she will be instructed 
to return it at the next visit. 
The study coordinator will question the patient on history of study product use since the last visit 
and will record any missed doses (as recorded on the patient diary) in both the source documents 
and the appropriate eCRF. A patient who deviates significantly from the prescribed dosage will 
be counseled. 
Study product should be stored at room temperature 20 to 25°C (68 to 77°F). Excursions permitted 
between 15 to 30°C (59 to 86°F). Do not freeze or refrigerate the product. 
18.5. 
Dosing Instructions 
Topical application of study product will be made to the face once daily at approximately the same 
time of the day, for a period of twelve (12) weeks. Study product will be applied as a thin coating 
that is gently rubbed in to the skin. 
Each patient will receive both verbal and written instructions (see Appendix 1) as to the proper 
dosing and study product application techniques. 
Patients will be instructed to apply the study product for 12 weeks, once a day after cleansing. No 
time interval between dosing and meals or any other activity is specified. 
Patients will cleanse their face with the given cleanser or sponsor approved cleanser using only 
the hands and pat dry with a soft clean towel. Patients will use a “pea-size” amount for each area 
of the face (chin, left cheek, right cheek, nose, left forehead and right forehead). The Patient should 
gently rub the cream into the skin. This amount of cream should be sufficient to cover the area on 
the face excluding the mouth, eyes, inside the nose, and lips. The Patient should wash his/her 
hands after application but should not wash face at least 2 hours after study product application. 
Patients should wait at least 30 minutes before applying moisturizer/sunscreen after application of 
study product to the face. During the trial that investigators remind patients to avoid exposure to 
sunlight and sunlamps and to wear sunscreen when sun exposure cannot be avoided. 
The Patients will be instructed to continue using the same supplied/approved facial cleanser and 
not to change products during the study. At each visit, Patients are to be asked if they have changed 
their cleansing routine. The supplied/approved cleanser and moisturizer/sunscreen should be 
applied according to the directions on the pump. Facial makeup (non-medicated) may be applied 
according to the patient’s normal daily routine (but not prior to 30 minutes after study product 
application); however, patients should be instructed not to apply the moisturizer or sunscreen or 
combination of them or wear make-up during study visits as it may interfere with the evaluator’s 
assessments. No other products should be used on the face.

Pump usage will be demonstrated by the site personnel on a sample pump at the clinic to help 
assure the patient understands the procedure. The patient will be provided a set of instructions 
(Appendix 1) that includes study reminders and restrictions as described in this protocol. Patients 
will be instructed to bring the study product to each visit and to not apply study product one hour 
prior to the study visit. Patients should be instructed to store the study product at room 
temperature, not in the refrigerator or freezer and informed that the test article may bleach colored 
fabric. 
18.6. 
Study Product Accountability and Study Records at Sites 
Upon receipt of the clinical supplies, the study staff will conduct a complete inventory of study 
products and assume responsibility for their storage and dispensing. In accordance with federal 
regulations, the Investigators must agree to keep all study products in a secure, temperature-
controlled location with restricted access. 
All supplies sent to the Investigators will be accounted for and in no case used in any unauthorized 
manner. All used and unused study product will be appropriately inventoried by the clinical site, 
and verified by the clinical monitor. 
Study product will be weighed before dispensing and upon return and weights will be recorded on 
the appropriate source document and eCRF. 
18.7. 
Return and Destruction of Study Product Supplies 
Upon completion or termination of the study, all remaining pumps (in kits) must be appropriately 
inventoried and returned to Sponsor or designee by a traceable method. All missing pumps of 
study products must be explained on the completed Clinical Supplies Return Form. The study site 
must keep a copy of the Clinical Supplies Return Form in the study file.

STATISTICAL CONSIDERATIONS 
19.1. 
General Statistical Methods 
All statistical processing will be performed using SAS® version 9.3 or later unless otherwise 
stated. Statistical significance will be based on two-tailed tests of the null hypothesis resulting in 
p-values of 0.05 or less.  These methods are intended to analyze the results of the study. 
The primary method of handling missing efficacy data will be based on estimation using the 
method of Markov Chain Monte Carlo (MCMC) imputation. This method provides robust 
estimation when the pattern of missingness is arbitrary. Additionally, the estimation will be done 
for each treatment group separately so that the pattern of missingness for one group does not 
influence the estimation of missing data for another group. Groups of complete datasets following 
the estimation will be concatenated to form analysis datasets for the comparative analyses and 
subsequent imputation result inference with SAS PROC MIANALYZE. Descriptive statistics will 
also be derived from the multiply imputed datasets. 
Additionally, a model-based multiple imputation process will be used as a sensitivity analysis to 
the MCMC imputation. Finally, the absolute change in lesion count will be analyzed using a 
repeated measures ANCOVA for lesion count data or a repeated measures logistic regression 
model (generalized estimating equations) for the dichotomized Investigator’s Global Assessment, 
IGA. 
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. 
19.1.1. 
Patient Disposition 
A tabulation of patient disposition will be provided. The tabulation will include the numbers of 
patients who enter the study, complete the study, and discontinue the study. The reasons for 
discontinuation will be included. 
19.1.2. 
Demographics and Baseline Characteristics 
Patient demographic and baseline characteristics will be summarized by treatment group for the 
ITT, PP, and safety populations. For continuous variables (e.g. age) comparisons among the two 
treatment groups will be conducted using a two-way analysis of variance (ANOVA) with factors 
of treatment group and analysis center (see Section 19.4.6 for definition of “analysis center”). 
Ethnicity and race will be analyzed with a Cochran-Mantel-Haenszel test stratified by analysis 
center. Past and current medical conditions, as well as history of disease will be presented in a 
data listing. 
19.1.3. 
Protocol Deviations 
All protocol deviations will be reported to the sponsor and recorded throughout the study. A 
tabulation of protocol deviations will be presented in a data listing. 
19.1.4. 
Analysis Populations 
Approximately 350 male and female patients at least 18 years of age with moderate or severe 
papulopustular rosacea with 3 or 4 [moderate to severe] on the IGA scale will be enrolled and 
randomized in the study with a 2:1 randomization ratio, it is anticipated that: 

SGT-54-01, Ver 4.0 
CONFIDENTIAL 
Page 64 of 85 
 
 
• 234 patients will be randomized to receive S5G4T-1, Encapsulated Benzoyl Peroxide (E-
BPO) Cream, 5% 
• 117 patients will be randomized to receive S5G4T-2, Vehicle Cream 
The ITT population will consist of all randomized patients who were dispensed study product. 
The safety population will be comprised of all randomized patients who are presumed to have used 
the study product at least once and who provide at least one post-baseline safety evaluation. 
An intent-to-treat (ITT) analysis will be conducted on all study patients. A per-protocol (PP) 
analysis will also be conducted. Patients will be eligible for the PP analysis if they complete the 
12-week evaluation without noteworthy study protocol violations (i.e., any patient or investigator 
activity that could have possibly interfered with the therapeutic administration of the treatment or 
the precise evaluation of treatment efficacy). The PP population will include patients in the ITT 
population who do not meet any of the following criteria: 
• Failed any of the inclusion/exclusion criteria; 
• Have taken any interfering concomitant medications; 
• Did not attend the Week 12 Visit; 
• Missed more than 1 post baseline study visit prior to Week 12 
• Have not been compliant with the dosing regimen (i.e., Patients may not miss more than 
five consecutive days of dosing and must take 80 to 120% of expected doses. The number 
of expected doses will be determined for each patient based on the length of their 
participation in the study); 
• Out of visit window (± 4 days) at the 12-week Visit. 
Patients 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 PP population. Data for these subjects 
will not be imputed by multiple imputation but rather their data will be imputed with values 
consistent with their status as treatment failures. 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. 
19.2. 
Study Product Evaluations  and  Analyses 
Inflammatory lesion count will be recorded for each patient at the Baseline and at Weeks 2, 4, 8 
and 12. The absolute and percent change from baseline of inflammatory lesions will be derived 
for each patient at Weeks 2, 4, 8 and 12. 
The IGA will be recorded for each patient at the Baseline visit and site visits at Weeks 2, 4, 8 and 
12 (End of Study). The IGA will be dichotomized into “success” and “failure” at Weeks 2, 4, 8 
and 12 with a patient considered a success for those visits if the IGA is at least 2 grades less than 
baseline and are Clear or Almost Clear. 
The Rosacea Erythema assessment, and Telangiectasia assessment will be recorded at Baseline 
and at Weeks 2, 4, 8 and 12. 
Patients will be asked to complete Patient Reported Outcome, PRO, questionnaires at appropriate 
time points. 
All statistical analysis will be conducted for both PP and ITT population.

Assessment of Efficacy 
Primary, secondary, and supportive efficacy analyses will be conducted on the ITT (primary) 
population. Primary efficacy analyses will be conducted on the PP (supportive) population. 
19.3.1. 
Primary Efficacy 
There are two co-primary efficacy endpoints: 
• Proportion of patients with the primary measure of success “Clear” (0) or “Almost clear” 
(1) in the IGA relative to Baseline at Week 12. 
• Absolute change in inflammatory lesion counts from baseline to Week 12. 
19.3.2. 
Secondary Efficacy 
The secondary efficacy endpoints will be the following: 
• Percent change in inflammatory lesion count from baseline to Week 12 
• Absolute change in inflammatory lesion count from baseline to Week 8 
• Proportion of patients with the primary measure of success “Clear” (0) or “Almost clear” 
(1) in the IGA relative to Baseline at Week 8 
• Absolute change in inflammatory lesion count from baseline to Week 4 
• Proportion of patients with the primary measure of success “Clear” (0) or “Almost clear” 
(1) in the IGA relative to Baseline at Week 4 
• . 
19.3.3. 
Supportive Efficacy 
Supportive efficacy endpoints include the following: 
• Percent change in inflammatory lesion count at Week 8 
• Percent change in inflammatory lesion count at Week 4 
• Mean change comparison in PAPSS item 1 (burning) between groups from Baseline to

Statistical Hypothesis Testing 
19.4.1. 
Test of Superiority for Lesion Count Variables 
This section provides the basic model and statistical approach which is used in combination with 
the multiple imputation procedures described in Section 19.4.6. Tests of superiority for the 
absolute change from Baseline in inflammatory lesions will be based on non-parametric methods 
consistent with the statistical assumptions required to support the analyses. Specifically, the tests 
of superiority will be based on ranked data submitted to an ANCOVA with factors of treatment 
and analysis center and the respective Baseline lesion count as a covariate. 
For informational purposes, a skewness test, based on the methods presented by Zar 1984, will be 
applied to the residuals resulting from an ANCOVA using the untransformed lesion count data. A 
two-sided p-value for the skewness test significant at 0.05 would validate the use of the non-
parametric method. The results of a non-ranked ANCOVA with factors of treatment and analysis 
center and the respective Baseline lesion count as a covariate will also be presented for 
informational purposes. 
19.4.2. 
Test of Superiority for IGA 
The IGA will be dichotomized into “success” and “failure” with a patient considered a success for 
those visits if the Investigator’s Global Assessment is at least 2 grades less than Baseline and 
“Clear” or “Almost Clear”. The analysis of the dichotomized IGA will be based on a logistic 
regression test with factors of treatment group and analysis center. 
19.4.3. 
Test of Superiority for Secondary Efficacy and Control of Multiplicity 
Appropriate descriptive statistics will be computed for all Secondary Efficacy parameters. 
Additionally, all inferential testing will follow the methods for the primary lesion count analyses 
as well as those for the dichotomized IGA success rates (as appropriate). 
The overall Type I error will be controlled by requiring the two co-primary efficacy endpoints to 
be statistically significant. Specifically, failure of either one of the primary efficacy endpoints will 
invalidate the statistical significance of the secondary efficacy endpoints. 

SGT-54-01, Ver 4.0

Page 67 of 85 
 
 
A stepwise process will be conducted for testing the secondary efficacy endpoints in order to 
control for multiplicity. These tests will be performed for only the ITT population. The testing 
process will terminate whenever a statistical test for a step is not significant. All subsequent tests 
for the remaining steps will be considered not significant. The order of testing is provided in 
Table 6.

Supportive Efficacy Analyses 
Appropriate descriptive statistics will be computed for all Supportive Efficacy parameters. 
Additionally, inferential testing for the following endpoints will use an ANOVA with factors of 
treatment, analysis center and the respective Baseline score. The overall Type I error will be 
controlled by the Benjamini-Hochberg method. Missing values will not be imputed. 
• Mean change comparison in PAPSS item 1 (burning) between groups from Baseline to 
Week 12

19.4.6. 
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 investigational site. The study is intended to be conducted in a manner 
such that a minimum of 5 patients will be enrolled in each treatment arm for any investigator. In 
the event that there are too few patients in a treatment arm for an investigator, then this 
investigator's data will be combined to achieve the desired sample size minimum per arm. The 
combining of investigator's data will be accomplished by taking the investigator with the smallest 
enrollment and combining it with the investigator with the largest 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 5 patients per treatment 
arm. The process of combining investigator data that have insufficient patients per treatment arm 
will result in redefining the groups of investigators for the purposes of statistical analyses. These 
combined groups will be referred to as "analysis centers" in the statistical analyses based on 
ANCOVA and stratified logistic testing. 
Prior to investigating the treatment effect within the analysis centers, the magnitude of the site 
mail effect will be investigated to determine if the main site-to-site variability is such that it could 
mask the analysis center effects. Thus, if computationally possible, a one-way ANCOVA (for 
lesion count variables) or a logistic regression analysis (for IGA) with a factor of site will be 
conducted prior to pooling. If the data structure interferes with the logistic regression, a descriptive 
analysis of the site effect will be undertaken. Conclusions appropriate to the findings of this step 
will be presented. 
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. An analysis center by treatment interaction will be included in the primary variable 
analyses to test for parallel treatment effect at an alpha level of 0.10. Change from baseline in 
inflammatory lesions will be analyzed with an ANCOVA (unranked or ranked) with factors of 
treatment, analysis center, and treatment by analysis center interaction and the respective baseline 
lesion count variable as a covariate. For the purpose of testing consistency of treatment response, 
the dichotomized IGA will be analyzed with a logistic regression procedure with factors of 
treatment, analysis center, and treatment by analysis center interaction. Further examination will 
follow for any variables that have a significant ANCOVA or logistic regression interaction term. 
In the event that the ANCOVA or logistic regression interaction (referred to henceforth as the 
"appropriate test") 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 outcome of the appropriate test has a 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 appropriate test. The process involves 
submitting subsets of analysis centers to the appropriate test and observing the appropriate test p-
value for the subset. Subsets with p-values greater than 0.10 for the appropriate test are 
considered homogeneous. 

SGT-54-01, Ver 4.0 
CONFIDENTIAL 
Page 69 of 85 
 
 
The search for an extreme analysis center begins by analyzing all subsets that can be created by 
excluding one analysis center. If one or more of the subsets result in an appropriate test p-value 
greater than or equal to 0.10, then the analysis center excluded from the subset with the largest p-
value for the appropriate test is deemed to be the extreme analysis center. 
If all appropriate test subset p-values are less than or equal to 0.10, then the process will analyze 
the appropriate test for all subsets that can be created by excluding two analysis centers.  If one or 
more of these subsets generate appropriate test p-values larger than 0.10, then the analysis centers 
excluded from the subset with the largest appropriate test 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 one, then two, then three, etc., analysis centers until the appropriate test 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 patients from the analysis in a non-random 
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. 
19.4.7. 
Missing Efficacy Data Imputations 
19.4.7.1. Lesion Count Variable Missing Data Imputation 
Missing Week 12 data will be estimated by multiple imputation and subsequently analyzed. 
Missing lesion count data will be derived for the analysis using the method of Markov Chain Monte 
Carlo (MCMC) multiple imputation. The pattern of missing observations in each treatment group 
cannot influence the missing value estimation in the other because the imputation will be 
conducted independently for each treatment group. 
Multiple imputation and subsequent analysis will involve 3 distinct phases with these principal 
tasks: 
1. Create a data set of patients, one for each treatment group, with observed values and those 
needing estimation by MCMC. The missing lesion count values in each data set will be 
filled in using the MCMC method 5 times to generate 5 data sets. The resulting data sets 
for each treatment arm will be combined into one complete data set for each imputation. 
Syntax: 
proc mi data=datain out=dataout seed=&seed. nimpute=5 
<options>; 
where trtpn=(1, or 2); 
mcmc chain=multiple; 
var baseline week2 week4 week8 week12; 
run;

Page 70 of 85 
 
 
2. For each complete data set, the variable of interest for baseline minus the Week 12 value 
will be computed. Each complete data set will be analyzed as specified for the particular 
analysis. 
3. The results from these analyses will be combined into a single inference using SAS PROC 
MIANALYZE. 
A total of 6 random seeds are needed to impute inflammatory lesion counts. These random seeds 
have been pre-specified by using a random number generator: 
• Inflammatory Lesion Counts Week 12 S5G4T-1: Seed = 2046620966 
• Inflammatory Lesion Counts Week 12 Vehicle: Seed = 693843173 
• Inflammatory Lesion Counts Week 8 S5G4T-1: Seed = 385596352 
• Inflammatory Lesion Counts Week 8 Vehicle: Seed = 386411964 
• Inflammatory Lesion Counts Week 4 S5G4T-1: Seed = 796550211 
• Inflammatory Lesion Counts Week 4 Vehicle: Seed = 40534656 
 
19.4.7.2. IGA Missing Data Imputation 
A similar procedure will be used for the analyses based on proportion of IGA successes wherein 
the ANCOVA analysis is replaced with a logistic regression analysis. Specifically, missing 12 
week IGA values from which the dichotomized IGA is derived will be estimated by (MCMC). 
The pattern of missing observations in each treatment group cannot influence the missing value 
estimation in the other because the imputation is being conducted independently for each treatment 
group. 
The missing 12-week IGA values will be derived for the analysis using the method of Markov 
Chain Monte Carlo (MCMC) multiple imputation. Multiple imputation and subsequent analysis 
will involve 4 principal tasks: 
1. Create a data set, one for each treatment group, of patients with observed values and those 
needing estimation by MCMC. The missing IGA values in each data set will be filled in 
using the MCMC method 5 times to generate 5 data sets. The resulting data sets for each 
treatment arm will be combined into one complete data   set   by   imputation. 
Syntax: 
proc mi data=datain out=dataout seed=&seed. nimpute=5

2. For each complete data set, the dichotomous success rate (clear or almost clear with a 2-
point change from baseline) will be computed. The 12-week estimated global values will 
be rounded to the nearest integer value prior to evaluating the success rate. Each 
complete data set will be analyzed with a logistic regression with factors of treatment group 
and analysis center. 
3. The results from these analyses will be combined into a single inference using SAS PROC 
MIANALYZE. 
A total of 2 random seeds will be needed to impute IGA for the two treatment groups. Those 2 
random seeds have been pre-specified by using a random number generator: 
• IGA Week 12 S5G4T-1: Seed = 712066910 
• IGA Week 12 Vehicle: Seed = 1200150465 
• IGA Week 8 S5G4T-1: Seed = 1871392013 
• IGA Week 8 Vehicle: Seed = 1866129897 
• IGA Week 4 S5G4T-1: Seed = 301965746 
• IGA Week 4 Vehicle: Seed = 812607204 
19.4.8. 
Sensitivity Efficacy Analyses 
19.4.8.1. Sensitivity Analyses for Absolute Change in Lesion Count 
The first sensitivity analysis for absolute change in lesion count will use a repeated measures 
ANCOVA, with treatment, analysis center, and visit (i.e., Weeks 2, 4 and 8) as independent factors 
and a covariate of baseline lesion count. In this analysis, data from all post-baseline visits will be 
included with no imputation for missing data. 
The second sensitivity analysis will use the model based multiple imputation method to impute 
missing data for the absolute change in lesion counts at Week 12. Although the full details will be 
presented in the Statistical Analysis Plan (SAP), the multiple imputation will involve 4 principal 
tasks: 
1. Missing values will be filled in 5 times to generate 5 complete data sets. The imputation 
model used will be an ANCOVA with factors of treatment group and analysis center, and 
a covariate of baseline lesion count (i.e., the imputation model will be the same as the 
analysis model). Appropriate modifications will be made should the analysis be based on 
a non-parametric method. 
2. Each complete data set will be analyzed with an ANCOVA with factors of treatment group, 
and analysis center, and a covariate of baseline lesion count. 
3. Results from these analyses will be combined into a single inference. 
19.4.8.2. Sensitivity Analyses for IGA 
The first sensitivity analysis for the dichotomized IGA success will use a repeated measures 
logistic regression model (generalized estimating equations), with dichotomized IGA success as 
the dependent variable and treatment, analysis center, and visit (i.e., Weeks 2, 4 and 8) as 
independent factors. In this analysis, data from all post-baseline visits will be included with no 
imputation for missing data.

The second sensitivity analysis will use the model based multiple imputation method to impute 
missing data for the dichotomized IGA data. Although the full details will be presented in the 
SAP, the multiple imputation will involve 4 principal tasks: 
1. Missing values will be filled in 5 times to generate 5 complete data sets. The imputation 
model used logistic regression with factors of treatment group and analysis center (i.e., the 
imputation model will be the same as the analysis model). 
2. Each complete data set will be analyzed with a logistic regression a factors of treatment 
group and analysis center. 
3. Results from these analyses will be combined into a single inference. 
19.4.9. 
Subgroup Analyses 
Subset analyses will be conducted for the ITT populations for the subgroups baseline global 
severity, gender, age, ethnicity, race, and geographic region. Age will be dichotomized to less 
than the median age of patients and greater than or equal to the median age of patients. Subset 
analyses will be conducted on the variables absolute change from baseline in inflammatory lesions 
at Week 12 as well as the dichotomized global severity score at Week 12. These analyses will 
contain only descriptive statistics. 
19.5. 
Assessment of Safety 
Safety will be evaluated by tabulations of adverse events (AEs), Cutaneous Safety Assessments 
for dryness and scaling, assessments for scores (erythema and telangiectasia) and Patient Global 
Impression of Treatment Side-Effects (PGI-SE) will be presented with descriptive statistics at 
Baseline and at Weeks 2, 4, 8 and 12 for each treatment group. Frequencies and percentages for 
each outcome category will be included in these statistics. Mean values will be presented 
graphically by week and treatment group. 
19.6. 
Adverse Events 
All adverse events occurring during the study will be recorded and classified on the basis of 
MedDRA terminology. Descriptions of AEs will include the date of onset, the date the AE ended, 
the severity of the AE, the relationship to study product, the action taken regarding study product 
usage, the action taken to treat the AE, and the outcome. All reported treatment-emergent AEs 
(TEAEs) will be summarized by the number of Patients reporting AEs, system organ class, 
severity, seriousness, and relationship to study product. TEAEs are those AEs with an onset on or 
after the date of the first study product application. 
Adverse events will be summarized by treatment group and severity. Each patient will be counted 
only once within a system organ class or a preferred term by using the adverse events with the 
highest severity within each category. 
Adverse events will be summarized by treatment group and relationship to study product. Each 
patient will be counted only once within a system organ class or a preferred term by using the 
adverse events with the greatest relationship within each category. 

SGT-54-01, Ver 4.0 
CONFIDENTIAL 
Page 73 of 85 
 
 
Comparisons among treatment groups will be made by tabulating the frequency of patients with 
one or more AEs (classified into MedDRA terms) during the study. The Fisher’s Exact test will 
be used to compare the proportion of patients in each treatment group who report any adverse 
event at a significance level of 0.05. The specific system organ classes and preferred terms 
analyzed will be those that are reported by at least one percent of the patients in any treatment 
group. 
All information pertaining to AEs noted during the study will be listed by patient, detailing 
verbatim given by the investigator, preferred term, system organ class, start date, stop date, 
severity, actions taken, and drug relatedness. The AE onset will also be shown relative (in number 
of days) to the day of initial dose of the randomized study product. 
Serious adverse events (SAEs) will be tabulated by patient within treatment groups. 
In addition, a list of patients who discontinued from the study and a list of patients who experienced 
SAEs will also be provided. 
19.6.1. 
Vital Sign Measurements 
Vital signs as well as changes from Baseline in vital sign measurements will be summarized with 
descriptive statistics for each treatment group at all applicable study visits. 
19.6.2. 
Concomitant Medications 
All previous therapies and concomitant medications will be classified based on terminology from 
the WHO Drug Dictionary. Previous therapies and concomitant medications data will be presented 
in data listings. 
19.7. 
Sample Size Determination 
The following power calculations are based on the observed Week 12 results of the Phase 2 study, 
SGT-EBP01-09. This study was a three-arm trial including E-BPO Cream, 1% and 5%, and 
Vehicle in the Treatment of Rosacea. Estimates from the E-BPO Cream, 5% arm were used in the 
power assessments. The anticipated randomization ratio is 2:1 for E-BPO Cream, 5% and Vehicle, 
respectively. The computations were performed with nQuery Advisor Version 7.0 using a two-
sided test with a statistical significance value of 0.05. 
A sample size of 86 in the E-BPO Cream, 5% and 43 in the Vehicle has group has 95% power to 
detect a statistically significant difference in the proportion of patients who have at least a 2-grade 
reduction at Week 12 from baseline in IGA and are Clear or Almost Clear. The estimated 
percentages with a 2-grade reduction at Week 12 from baseline in the IGA and Clear or Almost 
Clear are 53.3% and 20.0% for the E-BPO Cream and Vehicle, respectively. 
A sample size of 200 in the E-BPO Cream, 5% and 100 in the Vehicle group has 95% power to 
detect a statistically significant difference in inflammatory lesions. The estimated absolute change 
from baseline in treatment means were -14.1 and -7.4 for the E-BPO Cream and Vehicle, 
respectively, with a standard deviation of 6.70 and 17.24, respectively. 
The sample sizes above will be increased to give a planned enrollment of 234 in the E-BPO Cream, 
5% group and 117 in the Vehicle group since the Phase 3 trial is expected to enroll patients who 
are as a group more severe than those of the Phase 2 trial. This is a consequence of some changes 
in the inclusion criteria.
