1.7. 
Methodology 
The study will have 2 parts.  The first will involve 12 weeks of double-blind treatment with 
FMX-101, 4% or vehicle foam.  The second will involve up to 40 additional weeks of open-label 
treatment with FMX-101, 4% of subjects who complete the first part of the study. 
1.7.1. 
Part 1 – Double-blind Period 
This is a randomized, multicenter, double-blind, vehicle-controlled, 2-arm study to evaluate the 
safety and efficacy over 12 weeks of FMX-101 minocycline foam, 4%, compared to vehicle, in 
the treatment of subjects with moderate to severe facial acne vulgaris. 
Qualified subjects will be randomized to receive 1 of the following 2 treatments: 
• FMX-101, 4%  minocycline foam 
• Vehicle foam 
Subjects with qualifying lesion counts (Section 8.1.2) and Investigator’s Global Assessments 
(IGA, Section 8.1.1) of acne severity scores and will be assigned to 1 of 2 treatments according 
to the randomization schedule.  Subjects will apply the assigned study drug topically once daily 
for 12 weeks as directed.  Subjects will be advised to apply the study drug at approximately the 
same time each day, preferably in the evening at bedtime.  Both the Investigator and subject will 
be blinded to the study drug identity. 
Subjects will return for visits at Weeks 1, 3, 6, 9, and 12. At the discretion of the clinic staff, for 
the convenience of subjects or clinic staff, visits can be scheduled to occur 3 days before or after 
the nominal schedule date for the Weeks 1, 3 and 6 visits and 7 days before or after for the 
Weeks 9 and 12 visits.  Efficacy evaluations (acne lesion counts and IGAs will be performed at 
Weeks 3, 6, 9, and 12 during the study.  Other assessments will be performed as described in 
Section 9.  
1.7.2. 
Part 2 – Open-label  
At the Week 12 Visit, subjects whose IGA score has not worsened may be invited to continue 
into the open-label part of this study for an additional 9 months of treatment.  Subjects will be 
enrolled in this phase of the study until a total of approximately 400 subjects from Studies 
FX2014-04 and FX2014-05 have elected to continue in the open-label portion of their respective 
study.  Subjects who elect to continue into the open-label part of this study will receive supplies 
of active FMX-101, 4% minocycline foam.   
Treatment during this part of the study will be guided by each subject’s clinical response.  The 
Investigator may elect to suspend treatment of some or all areas if there is clinical improvement 
or resolution of the acne in those areas.  Even if the treatment is partially or completely 
temporarily suspended, the subject will be continued in the study and will make all scheduled 
clinic visits.  If at any time the acne recurs or worsens, treatment of the affected areas may be 
resumed.  
Subjects may be discontinued from the study after 12 weeks if their disease becomes refractory 
or they become intolerant of the product.

1.8. 
Number of Subjects 
The planned enrollment is 450 subjects.  Subjects will be randomized to active or vehicle in a 2:1 
ratio.  Approximately 300 and 150 subjects will be assigned to the FMX-101, 4% or vehicle 
treatment groups, respectively. 
1.9. 
Diagnosis and Main Criteria for Inclusion 
Subjects are to be at least 9 years of age. 
Eligible subjects are to have a diagnosis of facial acne vulgaris characterized by (subjects are 
permitted to also have acne on other parts of the body): 
• 20 to 50 inflammatory lesions (papules, pustules, and nodules) 
• 25 to 100 noninflammatory lesions (open and closed comedones) 
• No more than 2 nodules on the face  
• Investigator’s Global Assessment (IGA) score of moderate (3) to severe (4) 
1.10. 
Criteria for Evaluation 
1.10.1. Efficacy 
The efficacy assessments will include the IGA and lesion counts at Baseline and Weeks 3, 6, 9 
and 12.  
1.10.2. Safety 
The safety assessments in this study are physical examinations, vital signs, assessment of the 
skin at application site(s), adverse events (volunteered, observed, and elicited by general 
questioning in a non-suggestive manner), and clinical laboratory test results. 
1.11. 
Statistical Methods 
Efficacy analyses will be conducted on the Intent-to-Treat (ITT) population, using the last-
observation-carried-forward (LOCF) approach to impute missing values.  Supportive efficacy 
analyses will also be conducted on the Per Protocol (PP) population, with no imputation for 
missing values.  The co-primary efficacy endpoints are the absolute change from Baseline in the 
inflammatory lesion count at Week 12 IGA Treatment Success (dichotomized as Yes/No) at 
Week 12, where success is defined as an IGA score of 0 or 1, and at least a 2-grade decrease 
from Baseline.  FMX-101 4% will be tested against vehicle at the two-sided 0.05 level of 
significance without adjustment for multiplicity.  The absolute change from Baseline in 
inflammatory lesions at Week 12 will be analyzed using an Analysis of Covariance (ANCOVA) 
model with main effect treatment and investigational site as a covariate.  The IGA Treatment 
Success rates will be compared between the treatment groups using a Cochran–Mantel–Haenszel 
(CMH) test stratified for investigational site. 
No statistical tests will be performed for any of the safety assessments.

INTRODUCTION 
Acne vulgaris is a common disease of both males and females, usually manifesting initially 
during adolescence.  The primary pathologic events are initiated in the pilo-sebaceous units, 
especially of sebaceous-gland-bearing areas of the face, chest, and back as a result of increased 
androgen stimulation initiated at adrenarche or puberty.  As a result of both abnormal 
keratinization of the infra-infundibular portion of the pilo-sebaceous follicle and increased 
sebum produced in the gland, a blockage of the duct results in the inapparent clinical lesion of 
the microcomedone.  Continued blockage, colonization of the follicle by Propionibacterium 
acnes (P. acnes), and generation of multiple chemoattractant and proinflammatory moieties may 
result in non-inflammatory clinical lesions, comedones, and inflammatory lesions: papules, 
pustules, nodules, and cysts.1 
FMX-101, 4% is a minocycline containing topical foam being developed as a treatment for acne 
vulgaris.  Antibiotics, especially erythromycin, minocycline, and doxycycline, have been 
prescribed as acne treatments for many years.  These antibiotics effectively control the signs of 
inflammatory acne while patients continue to use them.  Nonclinical studies have demonstrated 
that FMX-101, 4% exhibits favorable characteristics.  
Foamix has conducted 2 Phase 1 and 1 Phase 2 study of FMX-101, 4% to assess its safety and 
tolerability.  FMX-101, 4% has been shown to be effective and well tolerated at the 4% dose that 
is being utilized in this study.  The Investigator’s Brochure should be consulted for summaries of 
the results of these studies.  
This Phase 3 study (Study FX2014-04) will assess the efficacy, safety and long-term safety of 
FMX-101, 4% for the treatment of moderate to severe facial acne vulgaris. 
3. 
 STUDY OBJECTIVES  
The objectives of this study are: 
• To evaluate the efficacy in the treatment of acne compared to vehicle of topical FMX-
101, 4% administered daily for 12 weeks 
• To evaluate the safety compared to vehicle of topical FMX-101, 4% administered 
daily for 12 weeks 
• To evaluate the long-term safety of topical FMX-101, 4% administered daily for up to 
an additional 40 weeks 
4. 
INVESTIGATIONAL PLAN 
4.1. 
Overall Study Design 
The one-year study will have 2 parts.  The first 12 weeks will be double-blind treatment with 
FMX-101, 4% or vehicle foam.  The remaining 40 weeks will involve open-label treatment with 
FMX-101, 4% by any subjects who complete the first part of the study.

4.1.1. 
Part 1 – Double-blind  
This is a randomized, multicenter, double-blind, vehicle-controlled, 2-arm study to evaluate the 
safety and efficacy over 12 weeks of FMX-101 minocycline foam, 4%, compared to vehicle, in 
the treatment of subjects with moderate to severe facial acne vulgaris. 
Qualified subjects will be randomized to receive 1 of the following 2 treatments: 
• FMX-101, 4%  minocycline foam 
• Vehicle foam 
Subjects with qualifying lesion counts (Section 8.1.2) and Investigator’s Global Assessments 
(IGA, Section 8.1.1) of acne severity scores and will be assigned to 1 of 2 treatments according 
to the randomization schedule.  Subjects will apply the assigned study drug topically once daily 
for 12 weeks as directed.  Subjects will be advised to apply the study drug at approximately the 
same time each day, preferably in the evening before bedtime.  Both the Investigator and subject 
will be blinded to the study drug identity. 
Subjects will return for visits at Weeks 1, 3, 6, 9, and 12.  Efficacy evaluations (acne lesion 
counts and IGAs will be performed at Weeks 3, 6, 9, and 12 during the study.  Other assessments 
will be performed as described in Sections 8.2 and 9. 
4.1.2. 
Part 2 – Open-label  
At the Week 12 Visit, subjects whose IGA score has not worsened may be invited to continue 
into the open-label part of this study for an additional 9 months of treatment.  Subjects will be 
enrolled in this phase of the study until a total of approximately 400 subjects from Studies 
FX2014-04 and FX2014-05 have elected to continue in the open-label portion of their respective 
study.  Subjects who elect to continue into the open-label part of this study will receive supplies 
of active FMX-101, 4% minocycline foam.   
Treatment during this part of the study will be guided by each subject’s clinical response.  The 
Investigator may elect to suspend treatment of some or all areas if there is clinical improvement 
or resolution of the acne in those areas.  Even if the treatment is partially or completely 
temporarily suspended, the subject will continue in the study and make all scheduled clinic visits.  
If at any time the acne recurs or worsens, treatment of the affected areas may be resumed.  
Subjects may be discontinued from the study after 12 weeks if their disease becomes refractory 
or they become intolerant of the product.   
4.2. 
Rationale for Study Design and Dose Selection 
A randomized, multicenter, double-blind, vehicle-controlled study design has been selected in 
order to assess the efficacy of the study drug in accordance with the FDA Guidance.2  The 
subjects will be selected according to predefined entry criteria.  The study will have a 12-week 
treatment duration.    
FMX-101 foam, 4% is a novel minocycline formulation that has been shown to have efficacy in 
once daily use in a Phase 2 study.  The once daily dosing regimen is appropriate given the 
pharmacokinetic characteristics of FMX-101, 4%.

Because of the mode of action of tetracycline drugs, the primary efficacy endpoints will be the 
effect on inflammatory lesion count and IGA (Section 8.1.1).  The effect on noninflammatory 
lesions will be the most important secondary endpoint.  
The extension of the study for an additional 40 weeks is necessary to obtain safety information 
about the long-term use of FMX-101, 4% to treat acne, which is a chronic condition.  The design 
of the study is expected to provide sufficient safety information to fulfill the ICH E1 guideline. 
5. 
STUDY POPULATION 
The planned enrollment is 450 subjects.  Subjects will be randomized to active or vehicle in a 2:1 
ratio.  Approximately 300 and 150 subjects will be assigned to the FMX-101, 4% or vehicle 
treatment groups, respectively. 
5.1.

STUDY PROCEDURES 
Potential subjects will be assessed for eligibility at Screening.  During this visit, the purpose, 
timing, procedures, and risks of the study will be explained to the subject, including 
requirements for enrollment and participation in the study, medication restrictions during the 
study, and requirements for washout of certain medications that the subject may already be 
taking.  
The eligible subject who is willing to participate in the study will then sign an appropriately 
administered Informed Consent Form (ICF) prior to any study-related procedures.  Subjects less 
than 18 years of age (or per state law) must sign an Assent Form for the study and a parent or 
legal guardian must sign the ICF. 
Procedures at the Screening Visit will include obtaining blood and urine samples for clinical 
laboratory tests.  These results must be no more than 30 days old at the time of Baseline Visit  
randomization.   
If a subject, who has agreed to participate in the study and signed the ICF or Assent Form, is 
currently undergoing acne therapy identified in Exclusion Criterion 12, they must first enter a 
washout period, before beginning the Screening procedures.   
A summary of study assessments and the time point at which they will be performed during the 
study is presented in Table 1.  If a subject prematurely withdraws from the study before the 
Week 12 Visit, the subject should return to the study site for a withdrawal visit, during which all 
evaluations described under Visit 6/Week 12 must be performed. 
See  
Table 2 and Section 6.2 for descriptions of the procedures required during the open-label part of 
the study.

Up to approximately 5,600 mg of minocycline assuming application of 0.5 gm of FMX-101 foam 
daily to the face for 280 days. Maximum total amount of drug dispensed contains 39.2 gm of 
minocycline. 
Dispensing 
Up to 2 Kits (4 canisters) dispensed at Weeks 12, 16, 22, 28, 34, 40 and 46 depending on rate of 
usage. Up to a total of 14 kits (28 canisters) dispensed to the subject for the study. 
7.1.3. 
Dosing Instructions 
7.1.3.1. 
Part 1 – Double-blind 
The dosing regimen will be the same for both treatment groups.  
After shaking the canister well, a small amount of foam (about 1/2 gram or a cherry-sized 
amount) should be expressed from the canister onto the fingertips of the hand and then rubbed 
into acne-affected parts of the face.  This should be repeated as needed until all acne-affected 
parts of the face are treated.  If acne is present on other parts of the subject’s body (neck, 
shoulders, arms, back or chest) additional amounts (up to a total of 4g) of foam should also be 
applied to these areas. The foam should be applied at approximately the same time each day 
preferably in the evening at bedtime. The subject should not bathe, shower or swim for at least 1 
hour after application of the product. 
Study kits of blinded drug supplies will be dispensed at Baseline and Weeks 1, 3, 6 and 9 to 
ensure continuous dosing in case the subject is late for subsequent visits.  
Dose adjustments are not permitted in this part of the study.  Subjects who require a dose 
adjustment or discontinuation of study drug must be withdrawn from the study (Section 11.4). 
7.1.3.2. 
Part 2 – Open-label 
At the Week 12 Visit, subjects who elect to continue into the open-label part of this study will 
receive supplies of active FMX-101, 4% minocycline foam.   
Treatment during this part of the study will be guided by each subject’s clinical response.  The 
Investigator may elect to suspend treatment of some or all areas if there is clinical improvement 
or resolution of the acne in those areas.  Even if the treatment is partially or completely 
temporarily suspended, the subject will be continued in the study and make all scheduled clinic 
visits.  If at any time the acne recurs or worsens, retreatment of the affected areas may be 
resumed. At each visit, the changes in treatment will be documented.  
Sufficient product will be dispensed at each visit to allow continuation of treatment as required. 
Subjects may be discontinued from the study at any time if their disease becomes refractory or 
they become intolerant of the product.

Manufacturer 
The manufacturer of the investigational product is ASM Aerosol-Service AG, Moehlin, 
Switzerland. 
7.1.5. 
Labeling of Study Drug  
The Sponsor, or designee will label study drug supplies according to the requirements of the 
Code of Federal Regulations (21CFR§ 210, Subpart G-Packaging & Labeling Control). 
The labels of the investigational (test) product will contain appropriate information as required 
by regional regulatory authorities and include, as needed, the following information: 
• Name and address of the Sponsor 
• Protocol number 
• Product name / dosage form / mode of administration 
• Kit Number / Canister Number 
• Site number / Subject number  
• Name and address of manufacturer 
• Date of manufacture 
• Lot/batch number 
• Canister contents 
• Storage conditions 
• Caution Statements:  
o “New Drug – Limited by Federal Law to Investigational Use” 
o “Flammable” 
o “Shake well before use” 
o “Keep out of the reach of children” 
The composition, pharmaceutical quality, batch number, and expiration date of the 
investigational (test) product will be traceable via the kit number. 
7.1.6. 
Storage of Study Drug 
FMX-101, 4% and vehicle canisters must be stored at 2°C – 8°C until being dispensed to the 
subjects.  Subsequently, they must be stored at 20°C – 25°C (refer to USP Controlled Room 
Temperature).  The investigator will be responsible for the suitable storage of the investigational 
product in compliance with the storage instructions and must restrict access to the study 
personnel only.

7.2. 
Study Drug Accountability 
The Investigator will have overall responsibility for the use of the study drug.  The Investigator 
or designee will verify the contents of the drug shipment and confirm receipt of the study drug in 
the Interactive Web Response System (IWRS) system.  In addition, an accurate study drug 
dispensing record that specifies the date and amount dispensed to each subject must be kept.  
This inventory record must be available for inspection by representatives of the Sponsor and is 
subject to regional regulatory authority inspection at any time.  At the conclusion of the study, 
the Investigator must provide a copy of this record to the Sponsor.  In addition, the weight of 
each canister will be determined prior to being dispensed to the subjects and each canister that 
has been retrieved from the subject will be returned to the vendor to be weighed. 
Under no circumstances will the Investigator allow the investigational drugs to be used other 
than as directed by this protocol.  Qualified study personnel must use the IWRS to assign and 
dispense kits to the subjects.  Reasons for digression from the expected dispensing regimen must 
also be recorded. 
7.3. 
Handling and Disposal of Study Drug 
The study drug must be protected from unauthorized access (eg, in a locked storage facility). 
Any unused, partially used, or empty bottles of study drug will be returned to the Sponsor or 
designee by the time of the site’s close-out visit.  Receipt, distribution, and return of the study 
drug must be properly documented on forms provided by the Sponsor or designee. 
7.4. 
Method of Assignment of Study Drug 
7.4.1. 
Part 1 – Double- blind 
After pretreatment clinical evaluations and all other screening procedures have been completed, 
authorized site personnel will acknowledge that the applicable subject met all the specified 
inclusion criteria and none of the exclusion criteria.  Assignment to a treatment group will then 
follow a predetermined list of randomization numbers, with each successive number receiving 
1 of the 2 treatments in random order.  Authorized site personnel will use the IWRS system to 
assign a kit number that corresponds to the randomization schedule.  The kit box with the 
assigned kit number will be dispensed to the subject.  
The randomization code will be provided by TKL.  
7.4.2. 
Part 2 – Open-label 
All subjects who elect to continue into the second part of the study will receive FMX-101, 4% 
minocycline foam as described in Section 7.1.3.2.        
7.5. 
Selection and Timing of Doses in the Study 
The 4% minocycline concentration of FMX-101 was shown to be more effective than 1% in a 
Phase 2 study.  The once-daily dosing regimen is appropriate given the pharmacokinetic 
characteristics of minocycline.

7.6. 
Blinding 
The first part of this study is double-blind with limited access to the randomization code.  The 
randomization code will be held in confidence until after the study database is locked and a 
memo documenting the database lock has been issued.  Every effort will be made to retain the 
integrity of the blind.  When issued to the sites, the study drug will be identical in appearance for 
all subjects, regardless of treatment assignment. 
The treatment each subject receives will not be disclosed to the Investigator, study site personnel, 
subjects, monitors, or the Sponsor staff except as required for the purposes of conducting this 
study. 
In the event that emergency identification of study drug is required (eg, if the Investigator 
believes that the information is necessary to properly treat a subject with an AE), the study drug 
identity can be obtained by the Investigator through the IRT system. 
Before breaking the blind for a subject, the Investigator should determine that the information is 
necessary (ie, that it will alter the subject’s immediate course of treatment and will contribute to 
the management of the AE).  In many cases, particularly when the emergency is clearly not 
related to study drug, the problem may be effectively managed by assuming that the subject is 
receiving active study drug without the need for unblinding.  Every effort should be made to alert 
the Medical Monitor before requesting that the blind be broken.  If this is not possible, the 
Medical Monitor should be immediately notified of the breaking of the blind.  The Investigator 
will record the unblinding procedures in the subject’s source documents. 
If unblinding is necessary, the subject will be withdrawn from the study and Week 12 Visit 
assessments will be completed. 
7.7. 
Prior and Concomitant Therapy   
Subjects should use the cleanser, Cetaphil Gentle Skin Cleanser (provided by the Sponsor).  An 
alternative, non-medicated, cleanser may be used if agreed to by the Sponsor. 
The use of or change in the dose of any and all concomitant medication, either prescription or 
over-the-counter, during the study will be recorded. The reason for use or change of dose of a 
concomitant therapy may need to be reported as an AE.  Therapies (medication and non-
medication therapies) not restricted by the protocol may be used.  Non-prohibited chronic 
therapies being used at Baseline may be continued. If a subject is using an oral contraceptive 
product, she should have been on the same product for at least 3 months and she should continue 
using the same or equivalent product for the duration of the double-blind portion of the study. 
If a subject is taking anticoagulant therapy, the subject should be advised that they may require a 
downward adjustment of their anticoagulant dosage. 
All topical or systemic medications listed in the exclusion criteria are prohibited during the 
double-blind part of this study (through Week 12).  Similarly, no other topical medications are 
permitted to be used on the face during this period.  Subjects requiring systemic antibiotics not 
known to affect acne will be considered on a case-by-case basis.   
During the open-label part of the study, concomitant acne medications are permitted; their use 
should be properly recorded. Benzoyl peroxide (e.g., Pro-Activ, Clearasil) can inactivate

minocycline and may thus decrease the effectiveness of FMX-101 if the two products are applied 
at the same time. Treated areas should be washed between applications of FMX-101 and 
products containing benzoyl peroxide.  Preferably, the products should be applied no less than 8 
hours apart. 
See the Investigators’ Brochure for information about tetracyclines and possible drug-drug 
interactions 
7.8. 
Use of Contraception 
Tetracycline-class antibiotics can cause fetal harm when administered to a pregnant woman.  
Tetracycline-class antibiotics used during tooth development (last half of pregnancy, infancy, 
and childhood to the age of 8 years) may cause permanent discoloration of teeth (yellow-gray-
brown). 
Prior to study enrollment, females of childbearing potential must be advised of the importance of 
avoiding pregnancy during study participation and the potential risk factors for an unintentional 
pregnancy. Females of childbearing potential include any female who has experienced menarche 
and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal 
ligation or bilateral oophorectomy) or is not postmenopausal (defined as amenorrhea > 12 
consecutive months).  Females of childbearing potential must have a negative urine pregnancy 
test and, if they are sexually active or become sexually active during the study, must use an 
effective method of birth control such as those listed below during the course of the study.  The 
following is not an all-inclusive list; the subject must discuss with the Investigator the most 
appropriate form of birth control: 
• Hormonal methods 
o Oral contraceptives – (Topical antibiotics may lessen the effectiveness of oral 
contraceptives. Therefore, a second form of birth control must be utilized in 
subjects using oral contraceptives) 
o Implant 
o Injection 
o Transdermal patch 
o Intravaginal Ring 
• Intrauterine Device (hormonal or non-hormonal) 
• Barrier methods 
o Condom (male or female) with spermicide 
o Diaphragm with spermicide 
• Abstinence 
7.9. 
Treatment Compliance 
Each subject is to be instructed on the importance of following the dosing schedule and returning 
all kits (empty/used/unused) at the appropriate visits.  The study personnel will question the

subject on the history of study drug use since the last visit. A subject who deviates significantly 
from the prescribed dosage will be counseled.

EFFICACY ASSESSMENTS 
8.1. 
Primary Efficacy Assessments 
The primary efficacy assessments will be the IGA and lesion counts. 
8.1.1. 
Investigator Global Assessment Score (IGA) 
Table 3 displays the IGA scale for acne vulgaris, which will be used by the investigators to 
assess the severity of a subject’s acne vulgaris.  The Case Report Forms (CRFs) will allow for 
Investigators to report lesions worsening beyond Grade 4 with treatment.    The IGA must be 
performed prior to the lesion count. 
The same evaluator should perform all evaluations for a subject; when this is not possible, 
another approved evaluator may perform the evaluations.

• 25 to 100 noninflammatory lesions (open and closed comedones) 
• No more than 2 nodules can be present on the face at Screening 
Lesions will be characterized as inflammatory or non-inflammatory using the following criteria: 
• Inflammatory lesions: 
Papule – a solid, elevated lesion less than 0.5 cm in diameter 
Pustule – an elevated lesion containing pus less than 0.5 cm in diameter

Nodule – palpable solid lesion greater than 0.5 cm in diameter; has depth, not 
necessarily elevated 
 
 
• Noninflammatory lesions: 
Open comedones (blackhead) – non-infected plugged hair follicle with 
dilated/open orifice; black in color 
Closed comedones (whitehead) – non-infected plugged hair follicle: small 
(microscopic) opening at skin surface 
Facial lesion counts will be made for the forehead, left and right cheeks, nose and chin at each 
visit.  Total inflammatory lesions (pustules, papules, and nodular lesions) and noninflammatory 
lesions (open and closed comedones) will be counted and recorded separately.  Lesion counts 
will be repeated at Weeks 3, 6, 9 and 12. 
8.2. 
Photography 
Photography of the face will be performed at Baseline and at Weeks 6 and 12 using recognized 
methods.  The equipment and techniques for this photography and for archiving the images are 
described in the Study Manual.  Photographs will be reviewed at the site and by the sponsor for 
quality.  Photographs will not be used to assess the lesion counts or the Investigator’s assessment 
of global severity but will be archived to be available for subsequent review, if required, by the 
sponsor, auditors or the FDA. 
8.3. 
Subject Satisfaction Questionnaire 
A satisfaction questionnaire will be administered at Visit 6, Week 12 and Visit 13, Week 52 (see 
Section 16.1, Appendix 1). 
9. 
SAFETY ASSESSMENTS 
The safety assessments in this study are standard safety measures in clinical studies, including 
physical examinations, the monitoring of vital signs, AEs (volunteered, observed, and elicited by 
general questioning in a non-suggestive manner), and clinical laboratory test results.  In addition, 
skin assessments at the drug application site(s) will be performed. 
9.1. 
Medical/Surgical History 
A complete medical and surgical history will be obtained at Screening, which will include 
diseases of the head, ears, eyes, nose and throat; respiratory diseases; cardiovascular diseases; 
gastrointestinal diseases, hepatic diseases, genitourinary diseases, musculoskeletal diseases, 
endocrine diseases, neurological diseases, psychiatric diseases, skin diseases, allergies, 
hematological diseases, and other abnormalities.

9.2. 
Medication History 
A history of medication usage (including previous use of acne medications and non-medication 
therapies) will be recorded at Screening.  The start and stop dates of previous use of medications 
in the last 3 months will be recorded. 
9.3. 
Concomitant Medications 
All medication that the subject is currently taking or any change in medication or dosage since 
the last visit will be documented throughout the study. 
9.4. 
Vital Signs 
Heart rate and blood pressure will be measured at all post-Baseline visits.  All blood pressure 
measurements will be made using a sphygmomanometer with an appropriate cuff size for the 
individual subject.  Measurements will be administered while the subject is seated after at least 
5 minutes at rest. 
9.5. 
Physical Examination 
A complete physical examination will include an evaluation of general appearance, skin, 
HEENT, neck, lymph nodes, lungs, heart, abdomen, musculoskeletal system, and neurologic 
system. A standard 12-lead EKG (after at least 5 minutes rest) will be performed at Baseline in 
subjects over 39 years of age. 
Weight will be recorded at the Baseline Visit, Visit 6 (Week 12) and Final Visit (Week 52).  
Height will be measured at Baseline, only. 
9.6. 
Clinical Laboratory Tests 
Serum chemistry, hematology and urinalysis will be evaluated at Baseline, Week 12/ Final Visit 
of the double-blind phase of the Study, and at Week 28 and Week 52/Final Visit of the open-
label phase of the Study. Serum chemistry, hematology, and urinalysis tests will be performed at 
a central laboratory. 
Refer to the manual from the central laboratory for detailed instructions on collecting,

Week 3, Week 6, Week 9 and Week 12 of the double-blind phase of the Study and Final Visit or 
when a subject prematurely withdraws from the study. 
Home pregnancy kits will be provided at each visit to all female subjects of childbearing 
potential in the open-label phase of the Study and are to be used at least monthly and if a 
pregnancy is suspected between visits (e.g., if a subject misses a period). A urine pregnancy test 
will be performed at Week 52/ Final Visit. 
9.6.2. 
Sample Collection, Storage, and Shipping 
Sample collection kits, requisition slips, and shipping boxes will be supplied by the central 
laboratory. Sample collection procedures and shipping instructions will be detailed in the 
laboratory manual. Study centers must be equipped to store the samples according to the 
laboratory manual procedures before shipping samples to the central laboratory. 
9.7. 
Other Safety Measurements 
9.7.1. 
Tolerability 
Erythema, dryness, hyperpigmentation and skin peeling at the sites of study drug application will 
be assessed by the investigator at each study visit on a scale of 0 to 3 (0=none; 1=mild; 
2=moderate; 3=severe). Itching will be assessed using the same scale based on the subjects’ 
subjective assessment.  The intensity and location of each finding will be recorded.  These signs 
and symptoms should not be recorded as AEs unless they require concomitant treatment or lead 
to the subject’s discontinuation from the study.

9.8. 
Adverse Events 
9.8.1. 
Method of Determining Adverse Events 
Safety assessments will include recording AEs reported spontaneously by the subject or observed 
by the Investigator.  AEs will be recorded at each visit throughout the study on the appropriate 
CRF. Every attempt should be made to describe the AE in terms of a diagnosis.  If a clear 
diagnosis has been made, individual signs and symptoms will not be recorded unless they 
represent atypical or extreme manifestations of the diagnosis, in which case they should be 
reported as separate events.  If a clear diagnosis cannot be established, each sign and symptom 
must be recorded individually. 
Subjects should be asked whether, since the time of the last observation or visit, they had any of 
the following: 
• Experienced any changes in well-being 
• Used any new medications 
• Changed medication regimens (both prescription and over-the-counter) 
• Were admitted to a hospital or had any accidents 
• Developed unusual headaches or changes in vision 
With the exception of the last item above, all questions should be of a general nature and should 
not suggest symptoms. 
When an AE is suspected, all relevant evaluations will be carried out and appropriate treatment 
provided.  Additional follow-up will be done as necessary (Section 9.8.4) and recorded in the 
subject’s source documents, and the results will be provided to the Sponsor. 
For AE definitions and reporting requirements, refer to Section 9.8.2 and Section 9.8.3, 
respectively. 
9.8.2. 
Adverse Event Definitions 
9.8.2.1. 
Adverse Events 
An adverse event (AE) is any unfavorable or unintended sign, symptom, or disease that appears 
or worsens in a subject after the subject signs the ICF (and/or Assent Form) for a clinical study. 
Examples of what may be considered an AE include any of the following: 
• A new illness 
• An exacerbation of a sign or symptom of an underlying condition or of a concomitant 
illness unrelated to participation in the clinical study or an effect of the study drug or 
comparator drug 
No causal relationship with the study drug is implied by the use of the term “adverse event.”  An 
exacerbation of a pre-existing condition/illness is defined as a more frequent occurrence or as an 
increase in the severity of the pre-existing condition/illness during the study.  Planned or elective 
surgical procedures for pre-existing conditions that have not worsened are not AEs.  However, 

FOAMIX 
         FMX-101, 4%     Protocol FX2014-04 Version 4 
 
 
Page 37 of 67 
 
 
CONFIDENTIAL 
 
any complication that occurs during a planned or elective surgery is an AE.  (If the event meets 
the criteria for a serious adverse event [SAE], such as an extended hospitalization, it will be 
considered an SAE).  Conditions leading to unplanned surgical procedures may also be AEs. 
9.8.2.2. 
Serious Adverse Events 
A “serious adverse event” (SAE) is any AE that: 
• Results in death 
• Is life-threatening 
(Note: The term “life-threatening” refers to any AE that, as it occurs, puts the subject 
at immediate risk of death.  It does not refer to an AE that hypothetically might have 
caused death if it were more severe.) 
• Results in hospitalization or prolongation of current hospitalization (not including 
hospitalization for a pre-existing condition that has not increased in severity or 
frequency from the subject’s underlying medical condition prior to entry into the 
study) 
• Results in persistent or significant disability/incapacity 
• Is a congenital anomaly/birth defect in the offspring of a subject 
• Is another serious (important medical events) events 
 
(Note: Important medical events may not be immediately life-threatening or result in 
death or hospitalization but may be considered serious when, based upon appropriate 
medical judgment, they may jeopardize the subject or require medical or surgical 
intervention to prevent one of the outcomes listed above.  Examples of such medical 
events include allergic bronchospasm requiring intensive treatment in an emergency 
room or at home; blood dyscrasias or convulsions that do not result in inpatient 
hospitalization; or development of drug dependency or drug abuse.) 
SAEs will be reported by the Sponsor to the regulatory authorities as required. 
9.8.2.3. 
Severity of Adverse Events 
“Severity” of the AE refers to the extent to which an AE affects the subject’s daily activities and 
differs from “Serious,” which is a regulatory classification.  Severity will be categorized 
according to the following criteria: 
• Mild:  The symptom has a negligible effect or no impairing effect on the subject’s 
normal function. 
• Moderate:  The symptom impairs the subject’s normal function to some extent. 
• Severe:  The symptom has an obvious, significantly impairing effect on the subject’s 
normal function.

CONFIDENTIAL 
 
9.8.2.4. 
Relationship of Adverse Events to Study Treatments 
“Causality” refers to the relationship of the AE to study drug and will be categorized according 
to the following criteria: 
• Unlikely:  There is no medical evidence to suggest that the AE may be related to 
study drug usage, or there is another more probable medical explanation. 
• Possible:  There is medical evidence to suggest that there is a reasonable possibility 
that the AE may be related to study drug usage. However, other medical explanations 
cannot be excluded as a possible cause. 
• Probable:  There is strong medical evidence to suggest that the AE is related to study 
drug usage. 
9.8.2.5. 
Adverse Events Expectedness 
Expected AEs are defined as those described in the Investigator’s Brochure.  If an event 
increases in intensity or severity from that described in the IB, it will be considered unexpected. 
9.8.3. 
Reporting Adverse Events 
AEs that occur from the time of informed consent/assent through completion of the last study 
visit should be reported.  Any AE that the Investigator becomes aware of that occurs within 30 
days of study completion or withdrawal should also be reported. 
Every attempt should be made to describe the AE in terms of a diagnosis.  If a clear diagnosis 
has been made, individual signs and symptoms will not be recorded unless they represent 
atypical or extreme manifestations of the diagnosis, in which case they should be reported as 
separate events.  If a clear diagnosis cannot be established, each sign and symptom must be 
recorded individually. 
Any serious AEs occurring in a subject receiving study drug must be reported to the Sponsor or 
designee within 24 hours of the site being informed of the event, even if the event does not 
appear to be drug-related.  The report must be made by sending a completed Serious Adverse 
Event (SAE) Report form to the Sponsor or designee.  Any pertinent follow-up information 
should be provided in a similar manner.  Contact information is provided below:  
 
 
9.8.4. 
Adverse Event Follow-up 
Adverse events, and tolerability signs and symptoms greater than zero (0), that are ongoing when 
a subject withdraws from or completes the study will be followed until resolution or stabilization 
(in the opinion of the Investigator), or for 30 days, whichever is shorter.  Investigators and the 
Sponsor will decide if longer follow-up is appropriate on a case-by-case basis.  Subjects who 
experience any clinically significant AE will remain under medical supervision until the 
Investigator or the Sponsor’s Medical Monitor deems the AE to be resolved, stabilized, or no 
longer serious enough to warrant follow-up.

Laboratory values that are abnormal and not assessed as AEs may be followed at the discretion 
of the Investigator or the Sponsor’s Medical Monitor until resolved or stabilized. 
9.8.4.1. 
Pregnancy reporting 
Prior to study enrollment, females of childbearing potential must be advised of the importance of 
avoiding pregnancy during study participation and the potential risk factors for an unintentional 
pregnancy.  The Informed Consent or Assent Form that the subject signs must document this 
discussion.  
If a subject or Investigator suspects that the subject may be pregnant prior to study drug 
administration, the study drug must be withheld until the results of laboratory pregnancy testing 
are available.  If pregnancy is confirmed, the subject must not receive study drug and must not be 
enrolled in the study. 
A urine pregnancy test will be performed on all females of childbearing potential at Baseline, 
Week 3, Week 6, Week 9 and Week 12 of the double-blind phase of the Study and Final Visit or 
when a subject prematurely withdraws from the study. 
Home pregnancy kits will be provided at each visit to all female subjects of childbearing 
potential in the open-label phase of the Study and are to be used at least monthly and if a 
pregnancy is suspected between visits (e.g., if a subject misses a period). A urine pregnancy test 
will be performed at Week 52/Final Visit. 
During the study, all females of childbearing potential should be instructed to contact the 
Investigator immediately if they suspect they might be pregnant (eg, missed or late menstrual 
period).  If a subject or Investigator suspects that the subject may be pregnant at any time before 
or during the study, the study drug must be withheld until the results of laboratory pregnancy 
testing are available.  The Sponsor and Site Monitor must be notified and available information 
captured on a “Suspected Pregnancy” form.  If pregnancy is confirmed, the subject must be 
withdrawn from the study and the Sponsor and Site Monitor notified.  Additional relevant 
information about the confirmed pregnancy will be recorded on the appropriate form(s) but the 
pregnancy will not be captured as an AE. 
The subject should be followed until the outcome of the pregnancy is known. 
9.8.5. 
Clinically Significantly Abnormal Laboratory Results  
All laboratory values that are outside of the normal range for that parameter will be so flagged 
when reported to the site.  The Investigator will determine which out-of-range laboratory test 
results should be characterized as clinically significant and will so annotate the laboratory report.  
If a clinically significant laboratory abnormality requires treatment or is the reason for a subject 
being discontinued from the study, the abnormal result must also be classified as an AE. 
9.9. 
Appropriateness of Safety Measurement 
The safety assessments in this study are standard safety measures in clinical trials.

STATISTICAL DESIGN AND ANALYSIS 
10.1. 
Statistical Analysis Plan 
A detailed statistical analysis plan will be finalized prior to breaking of the study blind. 
Descriptive statistics for qualitative variables (eg, race) will include the number and percentage 
of subjects with the qualitative response.  Missing responses will be enumerated, but the 
calculation of percentages will exclude missing responses.  For quantitative variables (eg, age), 
descriptive statistics will include the number of subjects with non-missing data, mean, standard 
deviation, median, minimum value and maximum value.  All hypothesis testing will be 
conducted using two-sided tests with α=0.05 level of significance unless otherwise specified. 
All study data will be presented in listings. 
10.2. 
Determination of Sample Size 
In a phase 2 study, the proportion of subjects with an IGA score of 0 or 1 after 
 of 
treatment was 
 in the minocycline 4% foam group compared to 2% in the vehicle group. The 
following table provides a few alternate assumptions and corresponding sample sizes. Power was 
set to 90% and type-1 error to two-sided 0.05. Sample size was calculated based on Fisher’s 
Exact test. 
Vehicle IGA (0,1) Minocycline 4% 
foam IGA (0,1) 
Sample sizes 
(vehicle, active) 
 
 
 
 
 
 
 
 
 
Assuming 
 dropout rate, 300 subjects on active, and 150 subjects on vehicle will provide at 
least 90% power for a statistically significant difference on IGA 0 or 1. In the same phase 2 
study, the change from baseline in inflammatory lesions was 
 in the minocycline 4% foam 
versus 
 in the vehicle group. The standard deviation in change from baseline was 
approximately 
 The following table shows alternate assumptions and corresponding sample 
sizes, for 90% power and a two-sided type 1 error of 0.05. The sample sizes were calculated 
using a t-test.

To summarize, using some conservative estimates of the effect on minocycline 4% foam versus 
the vehicle for both IGA and change in inflammatory lesions at week 12, 300 subjects on active, 
and 150 on vehicle will provide > 90% power for s statistically significant difference. 
Another consideration for the sample size must be given to the secondary endpoint of 
noninflammatory lesions which will be compared to the vehicle for non-inferiority. The margin 
for non-inferiority will be 
 of the change from baseline to week 12. In a phase 2 study, 
change from baseline in noninflammatory lesions at 
 was 
 for the vehicle group with 
a standard deviation of 18. Assuming approximately the same reduction at 
, a 
 non-
inferiority margin is about 
esions. The following table provides approximate sample sizes 
for alternate assumptions for 90% power to show non-inferiority.

If Minocycline 4% foam has the same effect on noninflammatory lesions as vehicle, 
 subjects 
on vehicle and 
 on 4% foam will be needed for 90% power to show non-inferiority. If 
Minocycline 4% foam has a slightly less effect on noninflammatory lesions

reduction versus 
 in vehicle), there will be about 90% power to show non-inferiority.

 Analysis Populations 
The Intent-to-Treat (ITT) population will include all randomized subjects. The ITT population 
will be the primary population for all efficacy analyses. 
The Safety population will include all randomized subjects who took at least one dose of study 
drug.  Subjects who have no post-Baseline assessments will be included in the Safety population 
unless all dispensed study drug is returned unused. 
The Per Protocol (PP) population is defined as the subset of the ITT population without any 
protocol deviations that may have an impact on the efficacy assessments.  The subjects to be

included in the PP population will be determined by the Sponsor/CRO prior to the unblinding of 
the study.  The PP population will be secondary for the co-primary endpoints only. 
Subjects may be excluded from the PP population if any of the following are met:  
• Did not meet inclusion/exclusion criteria 
• Have administered any interfering concomitant medications 
• Have not, in the opinion of the investigator, been compliant with the treatment 
regimen (e.g. reported frequent missed doses) 
Prior to breaking the blind, additional criteria for exclusion from the PP population may be 
included to accommodate for unforeseen events that occurred during the conduct of the study.  
10.4. 
Efficacy Endpoints 
The primary population for all efficacy analyses will be the ITT population.  Subjects will be 
analyzed according to their randomized treatment.  The primary method of handling missing data 
will be the last observation carried forward (LOCF) approach.   Sensitivity analyses using 
multiple imputations and baseline observation carried forward (BOCF) will be performed on the 
co-primary endpoints only. 
Supportive efficacy analyses will also be performed on the PP population.  All analyses using the 
PP population will use the Observed-Cases (OC) approach.  i.e., there will be no imputation for 
missing data at any time point. 
Changes from Baseline lesion count will be calculated as the Baseline value minus the post-
Baseline value.  Thus, a positive change will reflect a reduction in lesion count.  The percent 
change from Baseline lesion count will be calculated as the Baseline value minus the post-
Baseline value divided by the Baseline value, expressed as a percentage.  Thus, a positive 
percent change will reflect a reduction in lesion count. 
10.4.1. Primary Efficacy Endpoints 
The co-primary efficacy endpoints are: 
• The absolute change from Baseline in the inflammatory lesion count at Week 12 
• Treatment Success (dichotomized as Yes/No) at Week 12, where success is defined 
as an IGA score of 0 or 1, and at least a 2-grade improvement (decrease) from 
Baseline 
The null hypotheses of the equality of the FMX-101 4% and vehicle means for absolute change 
from Baseline to Week 12 in the inflammatory lesion count and the equality of IGA success rates 
at Week 12 will each be tested at a two-sided 0.05 level of significance. Change from baseline in 
inflammatory lesion count will be analyzed using an Analysis of Covariance (ANCOVA), with 
Treatment as a main effect, baseline inflammatory lesion count as a covariate, and 
investigational site a blocking factor. Investigational site by Treatment interaction will be tested 
at 0.1 level, and if significant, it will further be explored. The dichotomized IGA will be 
analyzed using a Cochran-Mantel-Haenszel (CMH) test, stratified by investigational site.

Safety endpoints   
Treatment-emergent adverse events (TEAEs), vital signs, physical examinations, and clinical 
laboratory measurements will be reported on the Safety population.  Subjects will be reported 
according to the treatment they actually received.  No statistical tests will be performed for any 
of the safety assessments. 
Baseline for vital signs, physical examinations, and clinical laboratory measurements is defined 
as the last non-missing value prior to the first dose of study drug. 
10.5.1. Adverse Events 
The Medical Dictionary for Regulatory Activities (MedDRA) terminology will be used to 
classify all AEs with respect to system organ class (SOC) and preferred term. 
TEAEs will be defined as events that emerge during treatment having been absent pre-treatment, 
or worsen relative to the pre-treatment state.  Summaries of AEs will be limited to TEAEs.  The 
number and percentage of subjects reporting each SOC and preferred term will be summarized 
for each treatment group and by the Study Period.  At each level of summarization, a subject will 
be counted once if he/she reported one or more events.  The severity of TEAEs and relationship 
to study drug will be summarized in a similar manner.  For summaries of relationship to study 
drug, a subject will be classified according to the closest relationship.  For summaries of TEAE 
severity, a subject will be classified according to the highest severity. 
Summaries of SAEs and subjects who prematurely withdraw from the study due to AEs will be 
presented.

10.5.2. Vital Signs  
Vital sign parameters will be summarized using descriptive statistics at Baseline and at each 
post-baseline time point.  Changes from Baseline will also be summarized.  Baseline is defined 
as the last non-missing value prior to the first dose of study drug. 
10.5.3. Physical Examinations 
Physical examinations will be summarized using descriptive statistics at Baseline and at each 
post-baseline time point.  Shifts from Baseline will also be summarized.  Baseline is defined as 
the last non-missing value prior to the first dose of study drug. 
10.5.4. Clinical Laboratory Results 
 
Baseline is defined as the last non-missing value prior to the first dose of study drug. 
Shift tables for each clinical laboratory test will cross-tabulate the number of subjects with values 
below the laboratory reference range (low), values within the laboratory reference range 
(normal) or above the laboratory range (high) at baseline with the number of subjects with low, 
normal or high values at each post-baseline time point.  
A listing of subjects with pre-treatment and treatment-emergent clinically significant abnormal 
laboratory values will be presented for each treatment group. Clinical significance is based on 
the Investigator’s judgment.

Statistical Analysis 
10.6.1. Interim Analysis 
 
No interim analysis is planned. 
10.6.2. Subject Accounting, Demographic, and Baseline Characteristics 
Demographic, baseline characteristics, and prior and concomitant medications will be 
summarized by treatment.  Study completion status and reasons for discontinuation will also be 
displayed by treatment.   
Medical and surgical history will only be presented in the listings. 
10.6.3. Efficacy Analysis 
The co-primary endpoint of absolute change from Baseline in inflammatory lesions at Week 12 
will be analyzed using an Analysis of Covariance (ANCOVA) model with main effect treatment 
and investigational site as a covariate.  The treatment by investigational site interaction will be 
tested separately at 0.1 level of significance, and if significant, will be further be explored.  A 
95% confidence interval will be calculated on the difference in mean changes from baseline 
between FMX-101 4% and vehicle. 
The co-primary endpoint of IGA Treatment Success rate at Week 12 will be analyzed using a 
Cochran–Mantel–Haenszel (CMH) test with investigational site as the stratification factor.  If the 
overall IGA Treatment Success rate is less than 10%, a Fisher’s Exact test will be used to

corroborate the CMH test.  A 95% confidence interval will be constructed on the difference in 
IGA Treatment Success rates between FMX-101 4% and vehicle. 
If FMX-101, 4% is found superior to vehicle (one-sided p<=0.025) for both co-primary 
endpoints, the secondary endpoints will be tested sequentially. The first secondary endpoint of 
noninflammatory lesions at Week 12 will be tested initially as a non-inferiority comparison of 
FMX-101, 4% to vehicle. Non-inferiority margin is defined as 
 of the noninflammatory 
lesion reduction in the vehicle group at Week 12. A lower 97.5% confidence limit will be 
calculated for µa-0.6×µv, where µa and µv are the mean reduction of noninflamatory lesions of 
FMX-101, 4% and vehicle respectively. If the confidence limit is above 0, non-inferiority will be 
concluded. If non-inferiority is concluded, the superiority of FMX-101, 4% to vehicle for 
noninflammatory lesions at Week 12 will be tested. The sequential testing will proceed 
according to the order in Section 10.4.2.1.  Testing of secondary efficacy endpoints at an earlier 
timepoint for each type of lesion and IGA Treatment Success will be performed only if 
superiority (one-sided p<=0.025) is seen at the later timepoint.  
Secondary efficacy parameters will be analyzed similar to the appropriate co-primary efficacy 
parameter. 
Absolute change from baseline in inflammatory lesion count and the IGA assessments in the 
open-label phase of the study will be summarized. No statistical testing will be performed for the 
open label efficacy data. 
10.6.4. Safety Analysis 
The Medical Dictionary for Regulatory Activities (MedDRA) terminology will be used to 
classify all AEs with respect to system organ class (SOC) and preferred term. 
TEAEs will be defined as events that emerge during treatment having been absent pre-treatment, 
or worsen relative to the pre-treatment state.  Summaries of AEs will be limited to TEAEs.  The 
number and percentage of subjects reporting each SOC and preferred term will be summarized 
for each treatment group.  At each level of summarization, a subject will be counted once if 
he/she reported one or more events.  The severity of TEAEs and relationship to study drug will 
be summarized in a similar manner.  For summaries of relationship to study drug, a subject will 
be classified according to the closest relationship.  For summaries of TEAE severity, a subject 
will be classified according to the highest severity. 
Summaries of SAEs and subjects who prematurely withdraw from the study due to AEs will be 
presented. 
Vital sign parameters will be summarized using descriptive statistics at Baseline and at each 
post-baseline time point.  Changes from Baseline will also be summarized. 
Physical examinations will be summarized using descriptive statistics at Baseline and for the 
final visit.  Shifts from Baseline will also be summarized. 
Shift tables for each clinical laboratory test will cross-tabulate the number of subjects with values 
below the laboratory reference range (low), values within the laboratory reference range 
(normal) or above the laboratory range (high) at baseline with the number of subjects with low, 
normal or high values at the Final Visit.

STUDY MANAGEMENT 
11.1. 
Monitoring 
The Investigator will be responsible for preparing and maintaining adequate and accurate source 
documents (medical records, raw data collection forms, etc.) designed to record all observations 
and other pertinent data for each subject treated with the study drug.  The Investigator will allow 
representatives of the Sponsor, contract designees, authorized regulatory authority inspectors, 
and the IRB to have direct access to all documents pertaining to the study.  The Investigator is to 
immediately notify the Sponsor or the Sponsor’s representative of any regulatory authority 
inspections.  The Investigator will be informed about the outcome of any Sponsor audit. 
This study will be monitored regularly, by or under supervision of a monitor from the Sponsor.  
The frequency of monitoring visits will be agreed upon by the Sponsor’s representative and the 
study site.  
Monitoring visits will take place on a regular basis according to the enrollment rate and number 
of subjects enrolled at each investigational site.  During these visits, the monitor will check the 
completion of the CRF entries, compliance with the study protocol and with GCP-ICH, and the 
agreement of key entries with the source data.  The monitor will also verify the correct use of the 
study drug.  At the Final Visit or at an agreed to time prior to the Final Visit, the monitor will 
check all remaining material including the remaining quantities of the study drug and will 
organize their return to the Sponsor or designee.  At each visit, the Investigator and staff will be 
expected to cooperate with the Sponsor’s representative(s) for the purposes of review and 
verification of protocol compliance, AE reporting, CRFs, source documents, clinical supplies 
and inventory records, and any additional records as may have been previously arranged between 
the Investigator and the Sponsor’s representative(s). 
The Investigator and/or other designated study personnel are expected to contact the Sponsor’s 
or the Sponsor’s representative’s clinical research associate, as needed, regarding study concerns 
and/or questions.  Contact information is provided in the Study Binder for the site. 
11.2. 
Protocol Amendments 
The Sponsor may propose to amend this protocol at any time. 
No change to the protocol will be implemented until the Sponsor and the IRB have reviewed and 
approved the amendment. 
In the event of an emergency, the Investigator shall implement any medical procedures deemed 
appropriate for subject safety.  All such procedures must have written documentation and be 
promptly reported to the Sponsor. 
Amendments to the protocol, if any, are included in Section 16.2, page 53.  This protocol version 
includes Amendment 1, effective February 26, 2016 and Amendment 2, effective April 6, 2016.

Protocol Deviations 
A protocol deviation is any change, divergence or departure from the IRB-approved protocol by 
the study staff (intentional or unintentional).  All deviations are to be documented at the site and 
reported to the IRB according to the IRB’s guidelines. 
In the event of an emergency, the Investigator shall implement any medical procedures deemed 
appropriate for subject safety.  All such procedures must have written documentation and be 
promptly reported to the Sponsor. 
11.4. 
Withdrawal of Subjects 
Withdrawn subjects are those who do not complete all evaluations and procedures outlined in the 
protocol.  Subjects who discontinue taking study drug for any reason must also be withdrawn 
from the study.  Subjects may be withdrawn from the study because of one of the following: 
• Adverse Event:  An AE that, in the opinion of the Investigator or Sponsor, suggests 
that continued participation in the study is not in the subject’s best interest for safety 
reasons.  All AEs that are present when the subject withdraws from the study will be 
followed as described in Section 9.8.4. 
• Abnormal Laboratory Result:  Any clinically significant laboratory abnormality 
that requires withdrawal of the subject from the study should be considered an AE 
leading to withdrawal.  If possible, laboratory tests will be repeated for any results 
that were clinically significantly abnormal until the abnormality is resolved or 
stabilized to the satisfaction of the Investigator in consultation with the Medical 
Monitor. 
• Lost to Follow-up:  Confirmed at minimum by 2 phone calls and a traceable letter 
without response. 
• Subject Request:  Subject requests, for any reason (eg, AE), to be withdrawn or 
withdraws his/her consent. 
• Poor protocol adherence:  A subject may be withdrawn from the study at the 
discretion of the Investigator or Sponsor due to poor compliance with protocol 
requirements that may compromise the study results or subject safety. 
• Other:  Other reasons include but are not limited to: Investigator decision that it is in 
the subject’s best interest to be withdrawn, administrative reasons, relocation of 
subject, etc.  If a subject becomes pregnant during the study, the subject will be 
withdrawn from the study and followed through conclusion of the pregnancy. 
If a subject is withdrawn from the study following the start of study drug during Period 1 of the 
study, all Week 12 assessments should be completed.  If a subject is withdrawn from the study 
following the start of study drug during Period 2 of the study, all Final Visit assessments should 
be completed.  Subjects withdrawn from the study will not be replaced.

11.5. 
Termination of the Study 
The study may be terminated at any time at the request of the Sponsor or a regulatory authority, 
with proper and timely notification of all parties concerned.  The IRB will be informed promptly 
and the Sponsor or the Investigator will supply reason(s) for the termination or suspension, as 
specified by the applicable regulatory requirements.  Otherwise, the study is considered 
terminated upon completion of all subject treatments and evaluations. 
11.6. 
Publication Policy 
The data obtained in this study are the property of the Sponsor, which will make reasonable 
efforts to assure that the results are published in a peer-reviewed journal.  As some of the 
information concerning the investigational product and development activities at the Sponsor 
may be of strictly confidential nature, any manuscript or other presentation of data must first be 
reviewed by the Sponsor before its submission.

ETHICS 
12.1. 
Conduct of the Study 
This study will be conducted in accordance with the ICH Harmonized Tripartite Guideline for 
GCP, 1997; the US Title 21 CFR parts 50, 56, and 312; and the ethical principles that have their 
origin in the Declaration of Helsinki.  The study will not begin until all of the requirements of the 
appropriate regulatory authorities have been fulfilled. 
12.2. 
Institutional Review Boards (IRB) 
This protocol (and any changes), all consent/assent forms, and subject consent procedures must 
be reviewed and approved by a properly constituted IRB.  The information presented to the IRB 
at the time initial approval is sought must include any plans for subject recruitment that involve 
advertising or other direct contact with potential subjects outside of the doctor-subject 
relationship.  A letter of approval issued by the IRB must be sent to the Sponsor prior to 
initiation of the study.  Any changes made to the protocol must be approved by the IRB prior to 
implementation, except where needed to eliminate a potential imminent safety hazard to the 
subjects.  In this case, immediate implementation may apply place followed by IRB approval. 
Review and approval by the IRB for continuation of the study must apply place at least once a 
year. 
12.3. 
Written Informed Consent 
The Investigator or designee will explain the nature of the study, its purpose and associated 
procedures, the expected duration and the potential benefits and risks of participation to each 
subject prior to his/her entry into the study (ie, before examinations and procedures associated 
with selection for the study are initiated).  Each subject will have ample opportunity to ask 
questions and will be informed about the right to withdraw from the study at any time without 
any disadvantage and without having to provide reasons for this decision.

Following this informative discussion, the subject will be asked if he/she is willing to sign a 
statement of informed consent.  Only subjects who voluntarily sign the Informed Consent Forms 
(ICF) may enter the study. Subjects less than 18 years of age (or as required by state law) must 
sign an Assent Form for the study and a parent or legal guardian must sign the ICF. 
The ICF and Assent Form must be reviewed and approved by the Sponsor and the IRB prior to 
their use. 
The original signed ICF and Assent Form will remain in the Investigator’s files.  The 
Investigator or designee will indicate in each subject’s source documents that he / she has 
informed the subject about the study and its procedures, the subject has signed and dated the 
ICF/Assent Form, and the subject has been given a copy of the documents.  The Investigator or 
designee will inform subjects of any new information that may be relevant to the subjects’ 
willingness to continue in the study. 
12.4. 
Subject Confidentiality 
The Sponsor ensures that the following have permission to review all study-related documents: 
monitor, auditor, IRB and regulatory authorities.  The subject’s identity and study-related records 
will remain confidential throughout the duration of the study data collection and reporting 
process. 
A unique subject identification code is assigned to each potential study subject.  The 
identification code protects the subject’s identity and is used in lieu of the subject’s name when 
reporting subject data.  The data will always maintain the confidentiality of the subject. 
The investigator or designee will review the subject data, which will be referenced using the 
subject identifier.  At the conclusion of the study, the data obtained may be presented to regional 
regulatory authorities but the subject’s identity will not be revealed.  In addition, if any clinical 
data obtained from the study is published in scientific journals or presented at scientific meetings 
the subject’s identity will not be revealed. 
12.5. 
Records Retention 
The Investigator must maintain essential study documents (protocol and amendments, source 
documentation corresponding to all information contained in the CRFs, signed informed consent 
and assent forms, relevant correspondence, and all other supporting documentation) until at least 
2 years after the last approval of a marketing application in an ICH region and until there are no 
pending or contemplated marketing applications in an ICH region, or at least 2 years after the 
formal discontinuation of clinical development of the investigational product.  These documents 
should be retained for a longer period if required by the applicable regulatory requirements or the 
hospital, institution, or private practice in which the study is being conducted.  Subject 
identification codes (subject names and corresponding study numbers) will be retained for this

Financing 
Funding for this study will be agreed between the Investigator and the Sponsor and will be 
confirmed in writing before the study starts. 
Completion of Financial Disclosure Forms will be required before the study starts.  Any 
additions to the primary site personnel will necessitate the completion of new Financial 
Disclosure Forms.  This information will also be collected at site closure and one year after the 
completion of the study. 
Disclosure Forms.  Investigators will be informed that they must report any new information to 
the sponsor or designate at site closure and one year after the completion of the study. 
13. 
QUALITY CONTROL AND QUALITY ASSURANCE 
The Sponsor and Investigator will apply all steps possible to ensure the accuracy, consistency, 
completeness, and reliability of the data, including participating in an Investigator meeting 
and/or site initiation visit, routine site monitoring, review of CRFs against source documents, and 
quality control checks.  
In addition, a representative from the Sponsor’s Clinical Quality Assurance (CQA) Department 
or designee may conduct periodic audits of the study processes, including, but not limited to, 
auditing the clinical site, laboratories, vendors and CROs, the clinical database, and the final 
study report. 
14. 
DATA HANDLING AND RECORD KEEPING 
This study will use web-based, electronic case report forms (eCRFs) developed through a 
validated, Electronic Records / Electronic Signatures-compliant platform (US Title 21 CFR Part 
11).  Foamix Clinical Data Management department or designee will create the electronic CRFs 
and corresponding clinical database based on the final protocol. 
All site personnel who will be using this system will receive formal training on the system, after 
which each person will be issued a unique user name and password.  Only the person who owns 
the user name and password will enter the system using that user name and password.  For data 
security reasons and to be in compliance with regulatory guidelines, usernames and passwords 
are not transferable. 
The Investigator is responsible for all data entered via the eCRFs and must confirm the accuracy 
of the data by electronically approving (signing) the eCRFs.  This responsibility includes the 
timely completion and accuracy of the data entered into the eCRFs by their site personnel as well 
as the review of some data entered directly into the database (eg, clinical laboratory results) by 
an external vendor.  The Sponsor will review the database to identify data errors or 
inconsistencies, which will be posted in the RDC system as queries for resolution. In addition, 
the Sponsor may make obvious corrections to the data in the database (eg, obvious errors in 
dates) and so inform the Investigator without issuing a query to the site.

7.7  Prior and 
Concomitant Therapy   
Inserted 
Benzoyl peroxide (e.g., 
Pro-Activ, Clearasil) can 
inactivate minocycline 
and may thus decrease the 
effectiveness of FMX-101 
if the two products are 
applied at the same time. 
Treated areas should be 
washed between 
applications of FMX-101 
and products containing 
benzoyl peroxide.  
Preferably, the products 
should be applied no less 
than 8 hours apart. 
Minimize potential for 
drug interaction 
9.8.1  Method of 
Determining Adverse 
Events 
All questions should be of a 
general nature and should 
not suggest symptoms. 
With the exception of the 
last item above, all 
questions should be of a 
general nature and should 
not suggest symptoms. 
Reminder that these AEs 
should be actively 
questioned.
