Principal statistical methods and 
sample size calculation: 
The Intent-to-Treat (ITT) population consists of all enrolled subjects. The 
safety population (APT) consists of the ITT population, after exclusion of 
subjects who never took the treatment. Population definitions will be 
decided before the database lock. 
 
The objective of this trial is to evaluate the subject reported outcome with 
Adapalene 0.3% - BPO 2.5% gel during 16 weeks of treatment.  
 
No inferential statistics will be performed. All variables will be descriptively 
summarized on ITT population and on APT population for the safety 
variables. The last observation carried forward (LOCF) method will be used 
to impute missing efficacy values. 
 
As no inferential statistics will be performed, no statistical rationale of 
sample size can be used. However, the subject reported outcomes (quality 
of life and satisfaction survey), can be evaluated with a total of 60 subjects.

2. BACKGROUND AND RATIONALE 
2.1. 
MEDICAL BACKGROUND AND SHORT RATIONALE FOR THE CLINICAL TRIAL 
Acne vulgaris is a chronic, inflammatory skin disease of the pilosebaceous unit, affecting 
approximately 80% of young adults and adolescents (Usatine R.P., 1998) (Leyden J J., 1995). 
Skin of color patients (typically Fitzpatrick skin types IV–VI) are no exception as shown in an 
epidemiological trial (Alexis A.F., 2007) that the diagnosis of visits from patients of different 
racial/ethnic backgrounds seen at a hospital-based dermatology practice in New York City were 
compared and acne was the most common reason for visits for both African American (28.4%) 
and Caucasian (21%) patients. It is the sequelae of the disease that are the distinguishing 
characteristics of acne in skin of color, namely Post Inflammatory Hyperpigmentation (PIH) or 
hypertrophic scarring. 
 
Currently, it is believed that acne in skin of color develops largely by the same pathogenesis that 
occurs in Caucasian patients. However, there is controversy over whether differences exist in 
certain biological characteristics of skin (such as sebum production and bacterial colonization) 
among various racial/ethnic groups. Several studies have been published evaluating racial/ethnic 
differences in sebaceous gland size and activity compared to Caucasians. (Kligman A.M., Shelley 
W.B. 1958) (Pochi P.E., Strauss JS. 1988). However, results have been contradictory. The trial 
evaluated 18 African-American and 19 Caucasian patients for differences in certain skin surface 
properties, such as sebum level, pH, moisture content, and barrier function and found no 
significant differences in sebum production between African-American and Caucasian patients. 
Another trial (Warrier A.G., 1996) examined facial skin microflora in 30 African-American and 
30 Caucasian women. The authors found a higher density of P. acnes in African-American 
patients compared to Caucasian patients; however, the results were not statistically significant. As 
acne is a chronic and relapsing disease normalizing follicular desquamation is then the key to 
achieve and maintain control of acne. Today it is established that retinoids such as Adapalene aid 
the differentiation and reduction of keratinocytes. 
 
Adapalene with Benzoyl Peroxide (BPO) is a unique antibiotic-free combination of Adapalene, a 
well-tolerated and efficacious topical retinoid, and BPO, a well-established antimicrobial agent. 
The complementary modes of action, efficacy and safety profiles of these two agents make 
Adapalene-BPO the most logical choice for once-daily treatment for all types of acne but the 
most severe. Adapalene possesses anti-comedogenic, comedolytic, and anti-inflammatory 
properties, whereas BPO, the most potent bactericidal agent, is more effective than topical 
antibiotics against P. acnes. (Brown J.M., Poston S.M. 1983) (Eady E.A., Cove J.H., Holland 
K.T., Cunliffe W.J. 1989) (Leyden J.J., 1983) (Lucky, A. W., 1987). 
 

GALDERMA RESEARCH & DEVELOPMENT 
Protocol N° RD.03.SPR.110232 
Version 03 Final - dated on 23-MAR-2017 US  
Page 18 of 72 CONFIDENTIAL 
Adapalene 0.3% - BPO 2.5% gel is efficacious to treat moderate to severe acne with a trend of 
superiority compared to other topical preparations in subjects with severe acne (Stein Gold L., 
2010). This suggests that the combination Adapalene - BPO both prevents the formation of new 
acne by reducing the number of primary and secondary lesions. However, it is also important to 
assess the local tolerability in terms of skin irritation and other skin barrier impairments in dark 
skin phototypes that might be caused by the treatment or by acne it-self. 
Maintaining skin hydration and avoiding sun exposure is recommended as part of the skin care 
regimen in acne patients. Minimizing skin irritation and photo-protection can be achieved by the 
use of non-comedogenic moisturizers with appropriate SPF that hydrate and protect the skin from 
UV irradiation (Schorr E.S., 2012) (Whitney P., Bowe M.Da. 2014) (Del Rosso, J. Q., 2013) 
(Zeichner, J., 2011). Using an appropriate cleanser will reduce oil on the face and will not affect 
skin hydration or the skin barrier function. 
Acne can persist for years and may affect seriously the psychosocial development, resulting in 
emotional problems, withdrawal from society, and depression (Koo , J Y et Smith, L L. 1991).If 
not treated, acne may cause serious physical and emotional scarring and can significantly impact 
the quality of life of those affected by the disease (Brown J.M., Poston S.M. 1983) (Usatine, R.P., 
1998) Therefore this trial aims to evaluate acne medication for assessment of subject satisfaction 
and quality of life in the dark skin subjects known to be sensitive with topical retinoids. The local 
tolerance of the treatment regimen in terms of erythema, scaling, dryness, stinging/burning will 
also be evaluated. 
 
This clinical trial is designed to evaluate the patient reported outcome with use of Adapalene 
0.3% - BPO 2.5% gel (Epiduo® Forte/TactuPump Forte) in subjects with dark phototype with 
moderate to severe acne vulgaris and also to assess this sub-population which was not specifically 
evaluated during the clinical development of Adapalene 0.3% - BPO 2.5% gel. 
2.2. 
INVESTIGATIONAL PRODUCT PROFILE 
The product used in this clinical trial (Adapalene 0.3% - BPO 2.5% gel) is marketed under the 
name Epiduo® Forte in USA and TactuPump Forte in Canada. TactuPump Forte is used for 
for sites in Mauritius and Singapore. Adapalene 0.3% - BPO 2.5% gel is well tolerated in subjects 
with acne vulgaris. See product monograph for detailed safety information. 
2.3. 
RISK/BENEFIT ASSESSMENT 
2.3.1. Risk-benefit statement related to the clinical trial products 
Adapalene 0.3% - BPO 2.5% gel (marketed under the name Epiduo® Forte / TactuPump Forte) 
is a commercial product that will be used according to the approved indications and usage. 
Warnings and precautions with Adapalene 0.3% - BPO 2.5% gel are well known and documented 
in the product monograph. For more details regarding the clinical adverse reactions and/or the 
post-marketing experience, please refer to the product monograph.

Page 19 of 72 CONFIDENTIAL 
2.3.2.  Risk-benefit statement related to the clinical trial 
Adapalene 0.3% - BPO 2.5% gel is an established and widely used marketed product and 
considered standard of care by many physicians and expert bodies for the treatment of acne 
vulgaris. It is therefore considered that exposure to the treatment over 4 months is covered by 
long-term safety data for the products Adapalene 0.3% and the combination of Adapalene 0.1% - 
BPO 2.5% which have shown that the safety profile remains stable with a long-term use. 
 
Treatment-related adverse reactions typically associated with use of Epiduo® Forte / 
TactuPump Forte gel include mild to moderate application site reactions, such as skin irritation 
characterized by scaling, dryness, erythema, atopic dermatitis, eczema, and burning/stinging. 
These reactions usually occur early in the treatment, and tend to gradually lessen over time. 
 
Any subject is free to discontinue his/her participation in this clinical trial at any time and for 
whatever reason, specified or unspecified, and without any prejudice.  No constraints are to be 
imposed on the subject, and when appropriate, a subject may be treated with other conventional 
therapy when clinically indicated. 
 
No invasive method will be conducted during this trial. 
 
Subjects will be followed (especially for Adverse events) regularly during all the trial, 
approximately once a month for 4 months. 
 
Consequently, based on available safety data and the proposed trial design, no safety issues other 
than those reported by the labelling are expected following topical administration of Adapalene 
0.3% - BPO 2.5% gel. 
3. 
CLINICAL TRIAL OBJECTIVES AND CLINICAL HYPOTHESIS 
3.1. 
CLINICAL TRIAL OBJECTIVES 
The purpose of this trial is to evaluate subject reported outcomes with the combination of 
Adapalene 0.3% - BPO 2.5%, Epiduo® Forte / TactuPump Forte gel, after 16 weeks of 
treatment of moderate to severe acne in dark skin phototypes (IV to VI). 
3.2. 
CLINICAL HYPOTHESIS 
The trial hypothesis is that daily acne treatment with Epiduo® Forte / TactuPump Forte is well 
tolerated as a treatment in moderate to severe acne in dark phototypes and improves subject’s 
quality of life. 
This trial has been designed to provide evidence in support of this hypothesis.

4.5.5. Prohibited therapies during the clinical trial  
The following drugs/procedures are prohibited because they may interfere with the 
efficacy/safety assessment of the investigational product, or because they may interact with the 
metabolism of the investigational product: 
 
 All topical or systemic drugs/procedures listed in exclusion criteria (section 4.4, criteria 10 and 
11), 
 Any irritating topical products (medicated or abrasive soaps and cleansers, soaps and 
cosmetics that have strong skin-drying effect and products with high concentrations of 
alcohol, astringents, spices, or limes), 
 Any other drugs/procedures which at the investigator’s judgement are liable to interfere or 
interact with the efficacy and the safety of Epiduo® Forte / TactuPump Forte® gel. 
If prohibited therapies become a necessary treatment for the safety or best interest of the subject, 
GALDERMA R&D should be notified to discuss possible alternatives prior to administration of a 
prohibited therapy and to discuss the pertinence and the modalities for the subject to continue in 
the clinical trial. 
4.5.6. Procedures / reasons for discontinuation 
An Investigator may decide to discontinue a subject from the clinical trial for safety reasons. 
Although the importance of completing the entire clinical trial should be explained to the subject 
by the clinical trial personnel, any subject is free to discontinue his/her participation in this 
clinical trial at any time and for whatever reason, specified or unspecified, and without prejudice.  
Subjects who discontinue the clinical trial prematurely should be fully evaluated, whenever 
possible. The procedures corresponding to the next theoretical visit should be performed (e.g. if a 
subject discontinues after week 2, complete the week 8 visit procedures). Additional final 
procedures will be conducted for all premature discontinuation as indicated in the trial flow chart 
section 5.4. The appropriate eCRF pages should be completed. 
For all subjects who prematurely discontinue the clinical trial, the reason must be carefully 
documented by the investigator on the Exit Form, and, if applicable, on the Adverse Event Form 
for discontinuation due to an AE.  
A subject who has been enrolled and assigned a kit number cannot be replaced by another subject 
if he/she discontinues the clinical trial for any reason. 
In the case of early termination, the investigator should ensure that the subject receives 
appropriate therapy for his/her condition.

INVESTIGATIONAL PLAN 
5.1. 
OVERALL CLINICAL TRIAL DESIGN 
This clinical trial will be conducted as a multi-centre, open-label prospective trial involving 
subjects aged at least 12 years old inclusive with dark skin type phototype IV to VI from one of 
the 3 ethnic/race backgrounds: Asian, Latin American and Black/African-American with 
moderate to severe acne vulgaris on the face and meeting other specific eligibility criteria. 
 
Approximately 60 subjects will be enrolled in 4 sites located in Mauritius, USA and Singapore. 
20 subjects are planned from each site. 
 
One third of subjects should have dark skin with Asian ethnic/race background: 
One third of subjects should have dark skin with Latin American ethnic/race background: 
One third of subjects should have dark skin with Black/African-American ethnic/race 
background: 

GALDERMA RESEARCH & DEVELOPMENT 
Protocol N° RD.03.SPR.110232 
Version 03 Final - dated on 23-MAR-2017 US  
Page 27 of 72 CONFIDENTIAL 
 
In each ethnic/race backgrounds (Asian, Latin American and Black/African-American) 
approximately one third of subjects should have “Severe acne” (IGA 4) and two third 
“Moderate acne” severity (IGA 3). 
 
All eligible subjects will receive Adapalene 0.3% - BPO 2.5% gel (Epiduo® Forte / TactuPump 
Forte gel) once daily on the whole face. 
There will be 5 trial visits: at baseline, week 2 (± 1 day), week 8 (± 3 days), week 12 (± 3 days), 
and week 16 (±5 days).  
5.2. 
DISCUSSION OF CLINICAL TRIAL DESIGN 
This clinical trial will assess subject reported outcomes with a product marketed in USA under 
the name Epiduo® Forte gel and TactuPump Forte gel in Canada, used according to its labeling 
information (indication, selected population, dose regimen). Therefore, this trial will be classified 
as Phase IV study in USA. Meanwhile, as this product is not marketed in Mauritius and 
Singapore (CTD recently submitted) therefore this trial is classified as a Phase IIIb trial for 
Mauritius and Singapore. 
According to clinical studies performed with Epiduo® in acne, 3 months treatment is sufficient to 
treat acne. As this trial aims to treat moderate to severe acne consequently, treatment period is 
fixed to 4 months as a maximum in order to have a complete cure of acne. 
Since acne is a chronic and long-lasting skin condition which could affect seriously the 
psychosocial development resulting in emotional problems it is deemed important to evaluate 
subjects’ quality of life before and after treatment.  
For this subjects will complete DLQI or cDLQI for children, at baseline, Week 12 and at last trial 
visit. 
A satisfaction questionnaire on use of the investigational product will be completed by subjects at 
Week 12 and at end of the trial. 
An acceptability questionnaire on use of the non –investigational products will also be completed 
by subjects at end of the trial. 
This clinical trial should allow evaluation of subjects’ reported outcome after use of the 
investigational product Adapalene 0.3% - BPO 2.5%.  
5.3. 
CLINICAL TRIAL DURATION AND TERMINATION 
The average planned period for the clinical trial from First Subject In (FSI) to Last Subject Out 
(LSO)] is 11 months. The end date of the clinical trial will be the date of the last visit of the last 
subject who participates in the clinical trial.

The planned duration of recruitment (i.e. From FSI to Last Subject In (LSI)) is approximately 7 
months. 
The clinical trial may be terminated by the investigator at his/her clinical trial site at any time 
with appropriate notification to GALDERMA R&D. Likewise, GALDERMA R&D may terminate 
the clinical trial and/or the participation of the clinical trial site(s) with appropriate notification. 
The expected duration of subject participation is 16 weeks.

6.1.2. Method of treatment assignment 
This will be an open label trial and all subjects will be dispensed with the investigational product. 
The kit number, a unique number will be assigned to each eligible subject at baseline according 
to the Inclusion/Non-inclusion criteria. 
A subject kit will be composed of: 

GALDERMA RESEARCH & DEVELOPMENT 
Protocol N° RD.03.SPR.110232 
Version 03 Final - dated on 23-MAR-2017 US  
Page 36 of 72 CONFIDENTIAL 
 Two visit boxes: One visit box will be dispensed to the subjects at Baseline (Dispensation 
1) and one at week 8 visit (Dispensation 2), 
One extra box to be dispensed in case if subjects loose or destroy trial treatment. 
Each box will contain:  
- Dispensation 1 (Baseline): 
 Two Epiduo® Forte / TactuPump Forte gel bottles 
- Dispensation 2 (Week 8):  
 Two Epiduo® Forte / TactuPump Forte gel bottles  
- Extra box:  
 One Epiduo® Forte / TactuPump Forte gel bottle 
At baseline visit, all eligible subjects will be dispensed a Baseline visit box from the subject kit in 
a chronological order of inclusion into the clinical trial, without omitting or skipping any number. 
If a number is omitted by mistake, the skipped kit number should be allocated to the next subject. 
 
6.1.3. IVR/IWR System  
Once a Subject has fulfilled inclusion/exclusion criteria and is qualified to enter into the trial, the 
site will call/connect to the IVR/IWR System to check trial inclusion rate as per ethnic/race 
background and acne severity stratifications and assign the Subject kit number. The IVR/IWR 
System acts as an automatic central recruitment center.  
The IVR/IWR System requires at least the Subject identification number (SIN) and Site number 
to provide proper treatment assignment number by linking the SIN to ethnic/race backgrounds 
and acne severity of the included subjects in the eCRF. 
6.1.4. Subject Identification Number (SIN) 
Upon signature of the informed consent, a subject meeting all inclusion/exclusion criteria will be 
allocated a unique subject identification number (SIN). This SIN number will be automatically 
generated by the eCRF.  
During the whole clinical trial, the subject will only be identified using the SIN for all 
documentation and discussion. 
6.1.5. Instructions for use and administration 
The Product Dispenser will give each subject verbal and written instructions on how to use the 
investigational product and non-investigational products. A specific focus on risks in case of 
pregnancy will be made for female subjects.  
 

GALDERMA RESEARCH & DEVELOPMENT

In addition, at the baseline visit the Product Dispenser will show the subject how to apply the 
investigational product on the face and how to record these applications in the subject diary. This 
procedure will be thoroughly discussed and reviewed at each trial visit. 
 
All subjects will apply the investigational product in the evening after washing their face, for 16 
weeks, as described in the instructions for use provided to the subjects. The procedure is as 
follows: 
1. Wash hands, 
2. Wash the entire face using the provided Cetaphil® DermaControl™ Oil Control Foam 
Wash, 
3. Blot dry the face with a soft towel. Do not rub the face, 
4. Apply a thin film of gel on the whole face avoiding eyes, lips and mucous membranes.

6.3. 
INVESTIGATIONAL PRODUCT MANAGEMENT 
6.3.1. Accountability 
Upon receipt of the clinical supplies at the site, the investigational product Dispenser will conduct 
a complete inventory of all investigational products and assume responsibility for their storage, 
accountability and dispensation. 
The Investigator or designee will sign the original “Receipt of Clinical Supplies” Form (or any 
acknowledgment of receipt) upon receipt and inspection of the supplies, fax the signed copy to 
GALDERMA R&D and retain the receipt in the Investigator Site File (ISF). 
All supplies sent to the investigator site will be accounted for and in no case used in any 
unauthorized situation.  
All used and unused investigational product will be appropriately inventoried by GALDERMA 
R&D /CRO representative and returned to GALDERMA R&D /designated contractor for further 
reconciliation and destruction. 
6.3.2. Dispensing 
All investigational and non-investigational products will be provided only to subjects enrolled 
into the clinical trial, at no cost and in accordance with the conditions specified in the protocol. 
 
Dispensation will be appropriately documented on the Product Dispensation Log by the Product 
Dispenser at each visit. 
 
It is important that no subject runs out of clinical trial supplies between visits.  
Each subject will receive a new visit box containing two bottles of investigational product at 
baseline and at post-baseline visit week 8. 
 
Treatment kits will be dispensed in ascending sequential order according to the chronological 
order of enrolment of subjects into the clinical trial. 
6.3.3. Investigational product compliance management and record 
Each subject will be instructed by the Product Dispenser about the importance of being compliant 
with clinical trial treatment(s) throughout the clinical trial as well as the importance of returning 
their investigational product (used and/or not used) at week 8 and week 16 (or at the end of the 
trial in case of early termination) visits. 

GALDERMA RESEARCH & DEVELOPMENT 
Protocol N° RD.03.SPR.110232 
Version 03 Final - dated on 23-MAR-2017 US  
Page 40 of 72 CONFIDENTIAL 
The investigational products will be collected, counted and documented on the Product  
Dispensation Log or other accountability document as applicable, at post-baseline visits (week 8 
and week 16), by the Product Dispenser. 
 
In this trial product compliance will be assessed using a subject diary. 
At Baseline visit, subjects will be provided with a subject diary to record on a daily basis the 
frequency of applications of investigational product (Epiduo® Forte / Tactupump Forte gel) and 
non-investigational products on the face and to record their compliance with the instructed 
application procedures. Subjects should return the diary at each post-baseline visit for review by 
the Product Dispenser. At the end of the trial week 16/early termination subjects should return the 
diary. 
The return of investigational products should be appropriately documented on the Product 
Dispensation Log by the trial Product Dispenser. All subject kits will be collected at the week 16 
visit at the latest, if not done before, or at Early Termination. 
Subjects will also be questioned regarding the application technique, intake, frequency and 
missed doses of investigational product and the use of any other additional topical, systemic 
product as well as OTC product. 
During the data review meeting, investigational product compliance for all subjects will be 
determined and reviewed by the sponsor’s clinical team. 
6.3.4. Storage of investigational product 
The investigator has to agree to keep all investigational products in a safe, temperature controlled 
and secure area with restricted access, in accordance with applicable regulatory requirements 
(e.g., in the site pharmacy, if applicable). 
Investigational products should be stored at appropriate storage conditions specified by 
GALDERMA R&D (see section 6.1.1). 
6.3.5. Return of investigational product 
The Product Dispenser will inform each subject about the importance of returning their 
investigational products (used and/or not used) at week 8 and week 16 at the latest, if not done 
before, or at Early Termination. 
In the event of early termination/suspension of the clinical trial for safety reasons, a rapid recall 
of the trial product(s) will be initiated.  The investigator or designee must immediately instruct all 
subjects to stop the clinical trial treatment regimen and return the investigational products to the 
clinical trial site. 
As a general procedure, GALDERMA R&D will provide the investigator with a detailed list of 
units being recalled so that any of the units remaining on site can be put immediately into 
quarantine.

6.3.6. Dose modification 
Local cutaneous reactions including erythema, scaling, dryness, and stinging/burning may be 
experienced with use of Adapalene 0.3% - BPO 2.5%. All these adverse reactions are easily 
managed depending upon the severity of these adverse reactions. 
 
Subjects should be instructed to use a moisturizer (the provided one for this trial) and if needed, 
investigators may reduce temporarily the frequency of the application of Adapalene 0.3% - BPO 
2.5% (eg. every other day), or temporarily discontinue use.  
 
These are most likely to occur during the first four weeks of treatment but are mostly mild to 
moderate in intensity, and usually improve with continued use of the medication. 
All dose modifications should be documented in the subject’s source data and reported in the 
eCRF (treatment compliance page). 
6.4. 
BLINDING 
6.4.1. Verification of blinding 
The trial design is considered as open label trial so blinding is not applicable for this trial. 
6.4.2. Unblinding during the clinical trial 
Not applicable for this open label trial. 
7. 
SUBJECT REPORTED OUTCOME, EFFICACY AND SAFETY ASSESSMENT 
7.1. 
SUBJECT REPORTED OUTCOMES 
The following Subject Reported Outcome (PRO) questionnaires should be filled out by the 
subjects. The investigator or delegate should check all questions of the PRO questionnaires for 
completeness prior to the subject leaving the office.

regarding use of investigational product they used in this trial (see Attachment 2). 
Subject satisfaction questionnaire will be translated in local language. 
7.2. 
EFFICACY ASSESSMENTS 
Clinical evaluations should be performed by the same evaluator (investigator or designee) 
throughout the clinical trial. If it is not possible to use the same evaluator to follow a subject, then 
evaluations should overlap for at least one visit in order to examine the subject together and 
discuss findings and this should be documented in the source documents. At least for the baseline 
assessments and the final assessments (Week 16/Early termination), the evaluator should be the 
same person. 
 
The evaluated areas must be examined under the same conditions of light exposure at each visit 
(same angle to avoid shadow and same light source, i.e. artificial or daylight). 
7.2.1. Investigator’s global assessment of acne severity (IGA) 
The evaluator will assess the severity of acne for the whole face of the subject using the scale 
described below. The evaluator will assess subject’s acne severity at each visit by performing a 
static (“snapshot”) evaluation of acne. The evaluator should make no reference to baseline or 
other previous visit when evaluating the subject’s acne.

SAFETY ASSESSMENTS 
Safety assessments will be conducted for all subjects at the baseline visit (after the ICF has been 
signed) and every subsequent visit. The safety parameters include adverse events (AEs) and 
increase in Post inflammatory hyperpigmentation (PIH) and local tolerance severity. 
7.3.1. Post inflammatory hyperpigmentation (PIH) 
Post inflammatory hyperpigmentation (PIH) is mostly seen in subjects with skin phototypes IV to 
VI (according to T.B. Fitzpatrick’s definitions). PIH lesions may represent the sequel of various 

GALDERMA RESEARCH & DEVELOPMENT 
Protocol N° RD.03.SPR.110232 
Version 03 Final - dated on 23-MAR-2017 US  
Page 44 of 72 CONFIDENTIAL 
cutaneous disorders as well as therapeutic interventions. The shapes of these lesions closely 
follow the contours of the original inflammatory dermatosis. Severity of PIH of the treated areas 
on the face will be evaluated by the evaluator at each visit as follows: 
Category

Severe 
4 
Large number of areas of post inflammatory hyperpigmentation; large 
in size and markedly darker than the surrounding skin. 
Any increase of PIH score during the trial is to be reported as an Adverse Event. 
7.3.2. Local tolerance assessment 
Local cutaneous signs and symptoms (erythema, scaling, dryness and/or stinging/ burning) are 
possible during treatment with Adapalene 0.3% - BPO 2.5%. 
 
The investigator will evaluate erythema, scaling, dryness and/or stinging/burning at each visit. 
The investigator will record stinging/burning after discussion with the subject regarding the 
previous application days. The investigator will ask an open-ended question, taking care not to 
influence the subject’s answer, such as: “Have you experienced any sensations immediately 
following product application (within 5 minutes)?” 
 
Erythema, scaling, dryness will be evaluated by the investigator, and stinging/burning will be 
recorded by the investigator after discussion with the subject. The four signs and symptoms will 
be graded at each follow up visit as follows:

Note: Stinging/Burning should NOT be assessed at the baseline visit 
 
An Adverse Event will be recorded if the severity of the signs and symptoms is such that: 
 The subject’s participation in the trial is interrupted at his/her request or at the 
investigator’s request after the first four weeks of treatment. 
 The subject permanently discontinues the treatment at his/her request or at the 
investigator’s request. 
 The subject requires concomitant prescription or OTC therapy (other than moisturizers). 
 
Note: Need for increased moisturizer use does NOT constitute an AE. 
 
Any new sign or symptom, which is not included in the scheduled evaluation of tolerability, 
should be recorded as an Adverse Event, including those of mild intensity. 
7.3.3. Adverse Events 
Adverse Events will be recorded monitored throughout the course of the clinical trial.  All clinical 
medical events, whether observed by the investigator or reported by the subject and whether or 
not thought to be product or trial procedure-related will be considered adverse events and 

GALDERMA RESEARCH & DEVELOPMENT 
Protocol N° RD.03.SPR.110232 
Version 03 Final - dated on 23-MAR-2017 US  
Page 46 of 72 CONFIDENTIAL 
recorded on the appropriate adverse event form of the eCRF with complete information as 
required.  If AEs occur, the main concern will be the safety of the subjects. At the time of the ICF 
signature, each subject must be provided with the name and phone number of clinical trial site 
personnel for reporting AEs and medical emergencies. 
7.4. 
OTHERS 
7.4.1. Cosmetic acceptability Questionnaire 
At Week 16/Early termination, subjects will complete an acceptability questionnaire regarding 
the non-investigational product they have been using in this trial (see Attachment 3). 
Subject cosmetic acceptability questionnaire will be translated in local language. 
7.4.2. Photographs 
Standardized digital photographs of the whole face (front, right and left) will be taken using a 
Canfield Scientific stereostatic device (Visia CR®) or equivalent. Detailed procedures will be 
provided. Subjects will be photographed at baseline and at each post-baseline visit.  
At Baseline visit subjects’ photograph will be used to confirm the severity of acne (moderate or 
severe) for inclusion of subjects into the trial. Sponsor Medical Expert will review the clinical 
evaluation of acne and give his confirmation for inclusion of subjects into the trial. 
7.5. 
APPROPRIATENESS OF MEASUREMENTS 
Efficacy is evaluated by assessing severity of acne by the investigator (IGA) and the degree of 
acne improvement versus baseline using the Global Assessment of Improvement (GAI) scores 
which are current and non-invasive techniques for assessing efficacy of acne treatment.  
Post inflammatory hyperpigmentation (PIH) is mostly seen in subjects with skin phototypes IV to 
VI (according to T.B. Fitzpatrick’s definitions). PIH lesions may represent the sequel of various 
cutaneous disorders as well as therapeutic interventions. Severity of PIH of the treated areas on 
the face will be evaluated by the the evaluator at each visit. 
Acne can persist for years and may affect seriously the psychosocial development, resulting in 
emotional problems, withdrawal from society, and depression (Koo , J Y., et Smith, L L. 1991). If 
not treated, acne may cause serious physical and emotional scarring and can significantly impact 
the quality of life of those affected by the disease (Brown J.M., Poston S.M. 1983) (Usatine, RP., 
Quan, MA et Strick, R. 1998). 
Therefore impact of trial treatments on subjects’ quality of life will be assessed using quality of 
life and satisfaction questionnaires in dark skin subjects known to be sensitive with topical 
retinoids. For this, subjects will complete the DLQI / cDLQI at baseline, Week 12 and at the end 
of the trial. A satisfaction questionnaire will also be completed by all subjects at Week 12 and at 
the end of the trial Week 16/Early termination.

To collect specifically subject’s feed-back on the associated non-investigational products used in 
the trial, a subject cosmetic acceptability questionnaire will be completed at the end of the trial 
Week 16/Early termination. 
Safety will be assessed through the reporting of adverse events and local tolerability assessment 
on an ongoing basis as a well-established process in clinical trials. 
8. 
ADVERSE EVENT 
8.1. 
DEFINITIONS 
8.1.1. Adverse Events (AE) 
According to ICH E2A, an AE is any untoward medical occurrence in a subject or clinical 
investigation subject administered a pharmaceutical product and which does not necessarily have 
a causal relationship with this treatment.  An AE can therefore be any unfavorable and 
unintended sign (including an abnormal laboratory value), symptom, or disease temporally 
associated with the use of a medicinal (investigational) product, whether or not related to the 
medicinal (investigational) product. 
Thus any new sign, symptom or disease, or clinically significant increase in the intensity of an 
existing sign, symptom or disease since the first visit (including the disease being treated), should 
be considered as an adverse event. Lack of efficacy should not be considered as an AE. 
Each new episode of a chronic disease (e.g., hay fever, allergy, etc.) from the screening visit 
should be reported as a new AE. 
Notes: 
 Any new sign or symptom reported by the subject that appears after accidental or intentional 
overdose or misuse should also be reported as an AE. 
 There should be an attempt to report a diagnosis rather than the signs, symptoms or abnormal 
laboratory values associated with the report of an AE.  However, a diagnosis should be 
reported only if, in the Investigator’s judgment, it is relatively certain.  Otherwise, symptoms, 
signs, or laboratory values should be used to describe the AE. 
 Pregnancy should not be considered as an adverse event but must be followed up as described 
in section 8.2.3.1. 
 For an AE of irritation, the “date of onset” should be the date that the first symptom occurred. 
There may be side effects during treatment with the investigational product, as described in the 
product monograph for Epiduo® Forte / TactuPump Forte gel and in this protocol (mild to 
moderate application site reactions, such as skin irritation characterized by scaling, dryness, 
erythema, and burning/stinging). 

GALDERMA RESEARCH & DEVELOPMENT 
Protocol N° RD.03.SPR.110232 
Version 03 Final - dated on 23-MAR-2017 US  
Page 48 of 72 CONFIDENTIAL 
The course of these expected events will be assessed and reported on the Local Tolerability 
Assessment Forms.  An Adverse Event Form will be completed only if the severity of the 
expected signs and symptoms is such that an interruption (after the first 4 weeks of 
treatment)/discontinuation of the subject’s participation in the clinical trial, at his/her request or at 
the investigator’s, occurred and/or if a concomitant medication is prescribed to treat the 
sign/symptom(s). 
8.1.2. Serious Adverse Events (SAE) 
A serious adverse event is any untoward medical occurrence that at any dose:  
 results in death, 
 is life-threatening, 
 requires hospitalization or prolongation of existing hospitalization, 
 results in persistent or significant disability/incapacity, or 
 is a congenital anomaly/birth defect. 
Important medical events that may not result in death, be life-threatening, or require 
hospitalization may be considered an SAE when, based upon appropriate medical judgment, they 
may jeopardize the safety of the subject, and may require medical or surgical intervention to 
prevent one of the outcomes listed in this definition. Examples of such events are intensive 
treatment in an emergency room or at home for allergic bronchospasm, blood dyscrasia, or 
convulsions that do not result in hospitalization. 
Note: 
 The term “life-threatening” 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 was more severe. 
 Inpatient hospitalization is considered to have occurred if the subject has had to stay in 
hospital overnight. The criterion for the prolongation of hospitalization is also defined as an 
extra night at the hospital. Hospitalization may not constitute sufficient grounds to be 
considered as an hospitalization if it is solely for the purpose of diagnostic tests, (even if 
related to an AE), elective hospitalization for an intervention which was already planned 
before subject enrolment in the clinical trial, admission to a day-care facility, social admission 
(e.g., if the subject has no place to sleep), or administrative admission (e.g., for a yearly 
examination). 
8.1.3. Unexpected adverse drug reaction 
According to ICH E6, an unexpected adverse Product reaction is defined as an adverse reaction, 
the nature or severity of which is not consistent with the applicable trial product information (in 
this clinical trial: the approved Canadian product monograph at the time of AE occurrence). 

GALDERMA RESEARCH & DEVELOPMENT 
Protocol N° RD.03.SPR.110232 
Version 03 Final - dated on 23-MAR-2017 US  
Page 49 of 72 CONFIDENTIAL 
8.1.4. Adverse event reporting period 
The clinical trial period during which AEs must be reported is the period from when the subject 
signs the Informed Consent Form to the end of the subject’s participation. 
The sponsor should be informed if the investigator becomes aware of any unusual safety 
information or any safety information that appears to be drug-related involving a subject who has 
participated in a clinical trial, even after a subject has completed the clinical trial. The 
investigator should be diligent in looking for possible latent safety effects that do not appear until 
a medication has been discontinued. 
8.1.5. Severity 
Severity is a clinical determination of the intensity of an AE and not of a disease. 
The investigator will classify the intensity of AEs using the following definitions as a guideline 
for all AEs occurring during clinical trials conducted or sponsored by GALDERMA. For this 
classification, the investigator will take into account the possible range of the intensity of the 
event and report the grade of intensity which is the most appropriate according  his medical 
judgment. 
Mild 
Awareness of sign or symptom, but easily tolerated 
Moderate 
Discomfort, enough to cause interference with usual activity 
Severe 
Incapacitating with inability to work or perform usual activity 
8.1.6. Relationship to the trial product(s) and/or clinical trial procedure 
The investigator is to determine whether there is a reasonable causal relationship between the 
occurrence of the AE and exposure to the trial product(s) and/or clinical trial procedure required 
by the protocol, such as moisturizer use. AE reporting for moisturizer use should be detailed, 
taking into account whether moisturizer use is recommended or mandatory. 
 
Medical judgment should be used to determine the relationship, considering all relevant factors, 
including pattern of reaction, temporal relationship, positive dechallenge or rechallenge, relevant 
medical history, and confounding factors such as co-medication or co-concurrent diseases. 
The expression “reasonable causal relationship” is meant to convey in general that there are facts 
or arguments to suggest a causal relationship (International Conference on Harmonization (ICH) 
E2A, section IIIA 1). 
The relationship assessment for an AE is to be completed using the following definitions as a 
guideline for all adverse events occurring during clinical trials conducted or sponsored by 
GALDERMA: 
Reasonable possibility: 

GALDERMA RESEARCH & DEVELOPMENT 
Protocol N° RD.03.SPR.110232 
Version 03 Final - dated on 23-MAR-2017 US  
Page 50 of 72 CONFIDENTIAL 
According to the reporting investigator, there is a reasonable possibility (i.e. suggestive evidence 
or arguments) that there is a causal relationship irrespective of the dose administered between: 
 The trial product (investigational product, active comparator, or vehicle, etc.) and the AE,  
 The clinical trial protocol procedure (e.g., UV-induction, biopsy, xylocaine injection, blood 
test or intraocular pressure measurement, ancillary products provided by the sponsor, such 
as moisturizers, etc.) and the AE. 
The Investigator has to complete these 2 causality assessments on the AE form. 
No Reasonable Possibility: 
No suggestive evidence or arguments can be identified regarding a causal relationship between 
the investigational product or the clinical trial protocol procedure and the AE. 
8.2. 
REPORTING PROCEDURES  
8.2.1. Procedures for reporting adverse events 
The collection of AEs is from the time that a subject signs the ICF to their final trial visit. 
At each post-baseline visit, the investigator (or sub-investigator) will enquire about adverse 
events using an open question taking care not to influence the subject’s answer (e.g., “Have you 
noticed any change in your health since the last visit?”). Direct questioning and examination will 
then be performed as appropriate. 
Any AE occurring during the AE reporting period, whether it is related to the trial product or not, 
will be recorded immediately in the source document, and described in the Adverse Event Form 
of the eCRF along with the date of onset, severity, relationship to the trial product, and outcome, 
without omitting any requested and known information.  Additional information will be requested 
under certain circumstances. Adverse Events (AEs) assessed as related to the treatment will be 
monitored until they are completely or satisfactorily resolved. Other AEs will be monitored until 
the last visit if they are not resolved or satisfactorily resolved. 
Adverse events assessed as related to the treatment or trial procedure will be monitored until they 
have resolved or reached a stable condition. Other AEs will be monitored until the last visit if 
they have not resolved or reached a stable condition. The investigator will obtain and maintain in 
the subject’s files all pertinent medical records, information and medical judgment from 
colleagues who assisted in the treatment and follow-up of the subject. If necessary, the 
investigator will contact the subject’s personal physician or hospital staff to obtain further details. 
For SAEs (see section 8.2.2) and pregnancies (see section 8.2.3.1), the Sponsor is to be informed 
immediately by e-mail/fax.  The event must be reported by fax or sent by e-mail to the Sponsor 
within 24 hours of receipt of the information (contact details in section 8.2.2).

8.2.2. Procedure for reporting a Serious Adverse Event 
For an SAE occurring during the period of the clinical trial, regardless of whether it is related to 
the treatment or not, and of whether it is expected or not, the investigator must do the following: 
1. 
Take prompt and appropriate medical action, if necessary. The safety of subject is the 
first priority. 
2. 
Ensure that the event is classified as an SAE. Immediately (no later than 24 hours) 
inform the Sponsor of the event by email/ fax/, and discuss further actions  to be taken:

3. 
Complete the SAE form provided by the CRA (Clinical Research Associate) at the start of 
the clinical trial (it is also available in the eCRF system as PDF document). Fax or send by 
email the completed form, accompanied by demographics, medical history and 
drugs/therapies forms (if any), and adverse event pages of the eCRF, and any other relevant 
information (e.g., test results) within 24 hours of receipt of the information to the Sponsor 
(see contact details above) 
4. 
Print and complete the Serious Adverse Event form (available in the EDC system as PDF 
document). Fax or send by email the completed form, accompanied any other relevant 
information or anonymized medical records (e.g., laboratory test results) within 24 hours of 
receipt of this information to the sponsor (see contact details above). The demographics, 
medical history, drugs/therapies forms, and adverse event pages of the eCRF must be 
completed and available for review in the EDC system at the time of the report. 
5. 
Monitor and record the progress of the event until it resolves or reaches a clinically 
stable outcome, with or without sequelae. For all additional follow-up evaluations, fax or 
send by e-mail all additional follow-up information on the SAE to the sponsor (see contact 
details above) within 24 hours of receipt of the updated information.  SAEs will be 
monitored until the Investigator and Sponsor agree that the event is satisfactorily resolved. 
6. 
Obtain and maintain in his/her files all pertinent medical records, information, and medical 
judgments from colleagues who assisted in the treatment and follow-up of the subject.  If 
necessary, contact the subject’s personal physician or hospital staff to obtain further details 

GALDERMA RESEARCH & DEVELOPMENT 
Protocol N° RD.03.SPR.110232 
Version 03 Final - dated on 23-MAR-2017 US  
Page 52 of 72 CONFIDENTIAL 
7. 
Inform the sponsor of the final outcome of the event. Send a revised or updated SAE 
form and AE form, if appropriate. 
8. 
Prompt notification of SAEs by the investigator to GALDERMA is essential so that legal 
obligations and ethical responsibilities towards the safety of subjects are met. GALDERMA 
has a legal responsibility to notify both the local regulatory authority and other regulatory 
agencies about the safety of a product under clinical investigation. GALDERMA will 
comply with country specific regulatory requirements relating to safety reporting to 
regulatory authorities, IRBs/IECs and investigators. Investigator safety reports are prepared 
for Suspected Unexpected Serious Adverse Reactions (SUSARs) according to local 
regulatory requirements and GALDERMA policy and are forwarded to investigators as 
necessary. An investigator who receives an investigator safety report describing an SAE(s) 
or other specific safety information (e.g., summary or listing of SAEs) from GALDERMA 
will file it with the Investigator’s Brochure (IB) and will notify the IRB/IEC, if appropriate 
according to local requirements. 
9. 
Comply with the applicable regulatory requirements related to the reporting of SAEs 
to your IRB/EC. 
8.2.3. Procedure for suspected allergic contact reaction 
This is a general procedure and further details can be discussed with the sponsor. 
 Stop the trial product 
 Take a picture of the affected area and the non-affected surrounding skin  
 Document the event and report it immediately to the sponsor by email/fax, within 24 hours of 
receipt of the information as described in section 8.2.2. 
In case of suspicion of allergic contact dermatitis  
1. 
After all signs and symptoms have resolved and after a minimum of two weeks from last 
dose application, a re-challenge test with the assigned trial product will be performed.  
2. 
Ensure the subject has not been under any treatment with corticosteroids or antihistamines, 
regardless of the route of administration, the week before testing. 
3. 
Ensure that the skin on the back has not been exposed to the sun or artificial ultraviolet 
sources the week before testing. 
4. 
Apply an appropriate quantity of the assigned trial product to fill the cupule of the test 
chamber on the skin of the upper back on either the right or left side of the center line (or 
the inner forearm if the back cannot be tested). If no test chamber is available on-site, patch 
test units will be provided. It may be preferable to perform the test under semi-occlusive 
conditions depending on the irritant potential of the trial product and the intensity of the 
reaction that was observed. The method to be used will be discussed with the sponsor.  
5. 
Choose a skin site that was not previously involved in the inflammatory skin reaction. 
6. 
Cover it for 48 hours with a hypoallergenic tape.

Protocol N° RD.03.SPR.110232 
Version 03 Final - dated on 23-MAR-2017 US  
Page 53 of 72 CONFIDENTIAL 
7. 
Subject should be informed about avoiding exercise, showers, application of toiletries 
products, etc. to keep the test system dry 
8. 
After 48 hours, remove the tests and evaluate the site: 
- At approximately 30 minutes after patch test removal (1st reading) and, 
- 24 to 48 hours later (i.e. 72 or 96 hours after application) (2nd reading). 
- A facultative 3rd reading may be performed 96 to 120 hours later (i.e. 6 to 7 days after 
application of the patch) if the overall assessment so far equivocal or if asked by the 
sponsor. 
- Pictures of the tested areas will be taken systematically at each reading and properly 
documented.

Report the results from the re-challenge test as directed by the sponsor and document with 
photographs. 
12. 
In case of absence of reaction, the subject may resume treatment if appropriate 
13. 
If the re-challenge is positive or equivocal, notify the sponsor immediately. Except specific 
situations, a new series of patch test will be initiated as directed by the sponsor (with 
individual ingredients at different concentrations if applicable, and possibly negative and 
positive controls) after a minimum of additional two weeks (but not later than 6 months) 
and after all signs and symptoms have resolved. The patch tests will be placed on the 
subject’s back (or the inner forearm if the back cannot be tested) distant from the site of the 
re-challenge test (e.g., the left upper back skin if the re-challenge test was done on the right 
side). Follow the same procedure for the patch test as for the re-challenge.  
14. 
In case of suspicion of immediate contact skin reaction (such as urticaria) 
A case by case approach will be applied and the procedure to follow will be discussed with the 
sponsor. 
8.2.3.1 
Procedures for reporting pregnancies 
Any pregnancy occurring during clinical trials, where the foetus could have been exposed to the 
investigational product(s), must be followed-up until outcome in order to ensure the complete 
collection of safety data on GALDERMA product. 
If a subject becomes pregnant, the Investigator is to do the following: 
1. 
Withdraw the subject from the clinical trial  
2. 
Complete all appropriate visit evaluations and eCRF pages. 
Immediately (no later than 24 hours) contact the Sponsor to inform them of the pregnancy 
occurrence and discuss further steps to be taken:

3. 
Complete, as fully as possible, the pregnancy surveillance form – Part I: History and 
start of pregnancy - provided by the CRA at the beginning of the clinical trial (it is also 
available in the eCRF system as pdf document), as fully as possible. Fax or send by email 
this pregnancy form along with the Exit form within 24 hours of receipt of the information 
to the Sponsor. 
4. 
Monitor and record the progress of the pregnancy until its outcome.  Contact the subject’s 
regular physician (general practitioner or gynecologist) or hospital staff to obtain further 
details and ask regular follow-up information. 
5. 
Inform the Sponsor of the progress by tri-monthly updates up to the final outcome of 
the pregnancy. For all the additional follow-up evaluations, fax or send by e-mail the 
additional follow-up information to the sponsor within 24 hours of receipt of the 
information.  If the subject can no longer be reached (lost to follow-up), documentation of 
the non-response/contact with two phone calls and a letter (certified with return receipt) is 
required. 
6. 
At outcome of pregnancy, complete as fully as possible the pregnancy surveillance 
form – Part II: Course and outcome of pregnancy, as full as possible. Inform the Sponsor 
by email/ fax, then fax or send by e-mail this pregnancy form to the Sponsor within 
24 hours of receipt of the information. 
7. 
If the pregnancy leads to an abortion (voluntary abortion, spontaneous abortion or 
therapeutic abortion), in utero death or congenital anomaly, follow the procedure for 
declaration of an SAE (see Section 8.2.2). 
8. 
If the investigator is informed of a developmental abnormality of the baby, even a long time 
after the end of the clinical trial, he/she must inform the sponsor and follow the procedure

STATISTICAL METHODS PLANNED 
9.1. 
STATISTICAL AND ANALYTICAL PLANS 
A Statistical Analysis Plan (SAP) will be developed as a separate document. The SAP will 
contain a more detailed and technical description of specific data conventions, calculations and of 
statistical procedures for executing the analyses that are specified in the sections of the clinical 
trial protocol below.  The SAP will be finalized prior to database lock. 
Any change made to the finalized SAP will be documented in the clinical trial report. 
The purpose of the trial is to evaluate subject reported outcomes with the combination of 
Adapalene 0.3% - BPO 2.5%, Epiduo® Forte / TactuPump Forte gel, after 16 weeks of 
treatment of moderate to severe acne in dark skin phototypes (IV to VI). 
9.1.1. Variables to be statistically analyzed 
The following variables will be analyzed: 
Subject reported outcome variable 
 DLQI/cDLQI at Baseline, Week 12 and last visit 
 Subject satisfaction questionnaire at Week 12 and last visit 
 
Efficacy variables 
 IGA score: % of subjects across scores at each visit 
 GAI score: % of subjects across scores at Week 12 and last visit 
 
Safety variables on safety population 
 PIH: Raw value at each visit and % change from baseline at each post-baseline visit 
 Local tolerance: Raw value at each visit and worst-score across visit, % of Subjects across 
scores at each post-baseline visit 
 Incidence of adverse events 
 Incidence of serious adverse events 

GALDERMA RESEARCH & DEVELOPMENT 
Protocol N° RD.03.SPR.110232 
Version 03 Final - dated on 23-MAR-2017 US  
Page 57 of 72 CONFIDENTIAL 
 
Other variables 
 Cosmetic acceptability questionnaire at last visit 
9.1.2. Populations analysed, evaluability and limitations / evaluation of Bias 
The statistical analyses will be performed based on the following subject populations. The 
definition of the populations will be finalized after a data review meeting. 
9.1.2.1 The Intent-to-Treat efficacy population (ITT) 
This population will consist of the entire population enrolled (i.e. assigned a kit number). The 
ITT population will be used for all variables except the safety variables. 
9.1.2.2 The Safety population (All subject treated [APT]) 
This population will consist of the Intent-to-Treat population, after exclusion of subjects who 
never used the treatment with certainty based on monitoring report. The APT population will be 
only used for the safety variables (AEs). 
9.1.2.3 Missing values 
The last observation carried forward (LOCF) method will be used to impute missing values of 
global assessment scores (GAI and IGA). If no post-baseline data are available, baseline will be 
carried forward. Thus, the number of subjects will not vary at each visit. The other missing values 
will not be replaced (observed data). 
9.1.3. Data presentation and graphics 
All continuous data will be summarized using usual statistics: number of values, mean, median, 
standard deviation, minimum and maximum, and by frequency distribution (n, %) for qualitative 
data. For ordinal data, both frequency distribution and usual statistics will be presented. All tables 
will be presented by clinical trial treatment and by visit (when applicable).  
Therapies that have been stopped before the baseline visit will be presented as prior therapies. 
Those reported at screening or starting between screening and baseline visits and still continuing 
after baseline will be classified as concomitant therapies. 
The adverse events will be descriptively summarized (n, %) for the safety population (APT). The 
adverse events will be descriptively summarized (n, %) by relationship to clinical trial treatments 
within System Organ Class (SOC) and preferred term (MedDRA). Subjects will be descriptively 
summarized (n, %) by intensity (i.e. mild, moderate and severe) of adverse events, SOC and 
preferred terms. Deaths and serious adverse events will be reported as well as withdrawals due to 
adverse events. A subject will be counted only once per System Organ Class (SOC) and only 

GALDERMA RESEARCH & DEVELOPMENT 
Protocol N° RD.03.SPR.110232 
Version 03 Final - dated on 23-MAR-2017 US  
Page 58 of 72 CONFIDENTIAL 
once per preferred term even if more than one occurrence of an event was reported within a SOC 
or preferred term. In the summary by categories of intensity, the adverse event with the highest 
intensity will be used. The subject will be counted only once per SOC (highest intensity whatever 
the AE within the SOC) and once per preferred term (highest intensity whatever the AE within 
the preferred term).  
9.1.4. Statistical analyses 
No inferential statistics will be performed. All variables will be descriptively summarized on ITT 
population and on APT population for the safety variables. The last observation carried forward 
(LOCF) method will be used to impute missing efficacy values. 
 
Any changes of the statistical analyses decided after the database lock will be justified and 
documented. 
9.2. 
SAMPLE SIZE DETERMINATION 
As no inferential statistics will be performed, no statistical rationale of sample size can be used. 
However, a total of 60 subjects to evaluate the subject reported outcomes (quality of life and 
satisfaction survey), can be considered as sufficient. 
10. 
TRAINING / MONITORING / DATA MANAGEMENT / QUALITY ASSURANCE 
A contract research organization (CRO) will be responsible for monitoring the clinical trial and 
the sponsor may perform co-monitoring visits at selected sites. 
10.1. PERSONNEL TRAINING 
Clinical Research Associates (CRA) will be trained prior to clinical trial initiation. During this 
training, an overview of the disease of interest and treatment will be presented. Specific 
monitoring guidelines and procedures to be followed during monitoring visits will be discussed. 
Initiation visits will be conducted with all Principal Investigators and site teams. During these 
visits, an extensive review and discussion of the protocol, procedures and eCRF will be 
conducted. Evaluation scales will also be reviewed. 
A trial reference monitoring manual will be provided to each CRA as an additional reference tool.  
An eCRF completion guideline will be provided to each CRA and site. These guidelines will 
contain instructions on how to fill-in the eCRF with some examples in order to standardize the 
eCRF completion as much as possible. 
A trial reference manual will be provided to each site as an additional reference tool. These 
guidelines will contain key CRO and Sponsor contacts and phone numbers and specific 

GALDERMA RESEARCH & DEVELOPMENT 
Protocol N° RD.03.SPR.110232 
Version 03 Final - dated on 23-MAR-2017 US  
Page 59 of 72 CONFIDENTIAL 
instructions for site in order to standardize as much as possible the assessments performed during 
the clinical trial.  
During the Investigator meeting/Initiation visit this document will be discussed and reviewed 
thoroughly. 
10.2. CLINICAL MONITORING  
The conduct of the clinical trial will be closely monitored by representatives of 
CRO/GALDERMA R&D to verify the adherence to the clinical trial protocol, ICH-GCP 
regulations, applicable standard operating procedures (SOPs), guidelines, and all local 
regulations.  
The investigator will allow representatives of GALDERMA R&D/CRO to have direct access to all 
clinical trial records, eCRFs, corresponding subject medical records, investigational product 
dispensing records and investigational product storage area, site facilities and any other 
documents considered as source documentation. 
The investigator also agrees to assist the GALDERMA R&D/ CRO representatives, if required. 
10.3. DATA MANAGEMENT 
A CRO will be responsible for data management in connection with the sponsor’s data manager. 
All data management procedures will be detailed in the Data Management Plan (DMP).  
The DMP will describe the Clinical Data Management System (CDMS) that will be used to 
collect and validate data. Computerized edit checks and review processes will be performed on an 
ongoing basis as outlined in the DMP until all data discrepancies are resolved. 
After all data discrepancies are resolved, coding is approved, and subject evaluability has been 
determined, the data will be exported to SAS datasets and will be locked. 
At the end of the trial the locked SAS database will be used to generate subject listings, 
tabulations and analyses.  
The data may be audited by the sponsor and/or CRO Quality Assurance department before or 
after the first statistical analysis results on the primary criteria. 
10.4. QUALITY ASSURANCE / AUDIT / INSPECTION 
The clinical trial will be conducted under the sponsorship of GALDERMA R&D in compliance 
with all appropriate local and local regulations as well as ICH guidelines and in accordance with 
the SOPs for clinical trial conduct and monitoring from GALDERMA R&D and/or the Contract 
Research Organization (CRO).
