Test: Tazarotene Cream 0.05% (Fougera Pharmaceuticals Inc.) 
• 
Reference: TAZORAC® (tazarotene) Cream, 0.05% (Allergan, Inc.) 
• 
Placebo: Placebo (vehicle) Cream (Fougera Pharmaceuticals Inc.) 
Dose and Route of 
Administration 
Subjects will be instructed to apply the investigational product (IP) 
topically, once daily, in the evening, for 84 days ± 4 days (12 weeks). 
Enough cream should be applied (2 mg/cm2) to cover only the lesions with 
a thin film. Hands should be washed thoroughly before and after each 
application. It is recommended that if a bath or shower is taken before 
application, the skin should be dry before applying the cream.  
Treatment Period 
84 days (12 weeks) ± 4 days 
Treatment 
Randomization 
1: 1: 1 (Test: Reference: Placebo) 
Subject Populations 
Approximately 855 male and non-pregnant female subjects, at least 18 years 
of age who meet all of the inclusion criteria and none of the exclusion 
criteria, will be enrolled in order to obtain
 subject in the modified Intent-
to-Treat (mITT) population and 
 subjects in the per-protocol (PP) 
population. 
The primary inclusion criteria are: 
• 
Clinical diagnosis of stable (at least 6 months) plaque psoriasis 
involving at least 2% and no more than 20% of Body Surface Area 
(BSA) not including the scalp and intertriginous areas

Study Design 
A multi-center, double-blind, randomized, vehicle-controlled, parallel-
group bioequivalence study with clinical endpoints comparing Tazarotene 
Cream 0.05% to TAZORAC® (tazarotene) Cream, 0.05% and both active 
treatments to a vehicle control in the treatment of stable plaque psoriasis. 
Investigative Sites 
Approximately 30 sites in the United States 
Study Conduct 
Eligible subjects will be randomized in a 1:1:1 ratio to one of the three 
treatment groups (Test, Reference or Placebo) at Visit 1. IP will be 
dispensed at Visit 1. Subjects will be instructed to apply enough cream 
(2 mg/cm2) to cover only the psoriatic lesions with a thin film. The first dose 
will be applied on the evening of Day 1. The subject will then continue to 
apply a thin film (2 mg/cm2) of the product once daily, in the evening, to 
cover only psoriatic lesions until the evening before Visit 4 (Day 85 ± 4 
days). Subjects will attend the following scheduled clinic visits: 
• 
Visit 1 - Screening/Baseline: Day -14 to 1 
• 
Visit 2 - Interim Visit: Day 28 ± 4 days 
• 
Visit 3 - Interim Visit: Day 56 ± 4 days 
• 
Visit 4 - End of Study/Early Termination: Day 85 ± 4 days 
Efficacy evaluations will be based on dermatological assessments 
performed in the clinic. The primary endpoint is the proportion of subjects 
with treatment success on the IGA at the Week 12 visit (Day 85 ± 4, End of 
Study). See Appendix A for IGA scale. 
Inclusion Criteria 
1. Male or non-pregnant, non-lactating female, ≥ 18 years of age with a 
clinical diagnosis of stable (at least 6 months) plaque psoriasis. 
2. 
 
 
3. Females of childbearing potential must not be lactating or pregnant at

Evaluation of 
Therapeutic 
Equivalence and 
Superiority 
The primary analyses for evaluating the therapeutic equivalence of the Test 
and Reference treatments, and the superiority of each active treatment over 
the Placebo, will be based on the proportion of subjects with treatment 
success (defined as "none, minimal or mild disease, a score of 0, 1 or 2, 
within the treatment area") on the IGA at Week 12 visit (Day 85 ± 4, End 
of Study). 
The statistical analyses for equivalence for binary outcomes for the primary 
and two secondary endpoints will be based on a Yates’ continuity-corrected 
confidence interval on the Test minus Reference difference (T-R) in 
proportions. Superiority will be tested at the 5% significance level using a 
Cochran-Mantel-Haenszel exact test stratified by clinical site for Test versus 
Placebo and Reference versus Placebo for the three endpoints. 
Therapeutic Equivalence Analysis 
Therapeutic equivalence will be evaluated for both primary and secondary 
endpoints using the PP population, with results in the mITT population 
being supportive. For the dichotomized primary endpoint (proportion of 
treatment success), if the 90% confidence interval (with Yates’ Correction 
Factor) of the difference between the proportion of subjects considered a 
“treatment success” in the Test and the Reference treatment groups at Week 
12, compared to Baseline, is contained within the pre-defined equivalence

limits [-20%, +20%], then therapeutic equivalence will be considered to 
have been supported for the endpoint. The same statistical approach will be 
conducted for analysis of the two dichotomized secondary endpoints in the 
PP and mITT populations. 
To declare therapeutic equivalence of the Test product to the Reference 
product, therapeutic equivalence must be demonstrated for only the primary 
endpoint in the PP population. 
Superiority to Placebo Analysis 
The primary measure of superiority will be evaluated using the mITT 
population and last observation carried forward (LOCF) for missing 
efficacy values. The results in the PP population will be considered 
supportive. The superiority of the Test and Reference products over Placebo 
will be concluded for the primary endpoint if the proportion of treatment 
success at Week 12 is statistically superior to Placebo (p < 0.05, two-sided) 
using the mITT population and LOCF. The same statistical approach will 
be conducted for analysis of the two dichotomized secondary endpoints in 
the mITT and PP populations. 
To declare superiority of the Test and Reference products over Placebo, 
their superiority must be demonstrated for only the primary endpoint in the 
mITT population. 
Safety Analysis 
Adverse events (AEs) will be classified using standard MedDRA 
terminology Version 18.1 or higher and summarized by treatment group. 
Summary tables comparing the type, date of onset, date of resolution, 
incidence, severity, relationship to the IP, outcome and action taken will be 
prepared by treatment group. Should sufficient data exist, AE frequencies 
will be compared among treatments using Fisher’s exact test or a similar 
test. Application site reactions (erythema, dryness, burning/stinging, 
erosion, edema, pain, itching) recorded at each visit will be compared 
among treatment groups. A descriptive analysis comparing the application 
site reactions for each treatment group will be created. 
Concomitant medication use during the treatment period will be tabulated 
by subject. 
Signs and symptoms of psoriasis will not be considered AEs, unless in the 
Investigator’s opinion, they have increased in frequency and/or severity to 
such an extent that the Investigator/subject considers that it is in the 
subject’s best interest to be dropped from continued participation in the 
study and given alternative therapy for their condition. 
All randomized subjects who received IP will be included in the 
comparative safety analysis.

Reference treatment after 12 weeks of treatment is expected to be 
approximately 
 in the PP population. Assuming that the rates of 
treatment success for Test and Reference treatments are the same, a sample 
size of 
 subjects in each active group in the PP population will provide 
approximately 
 power to demonstrate therapeutic equivalence (i.e., the 
90% confidence interval (Yates’ continuity-corrected) of the absolute 
difference between the Test and Reference rates of treatment success is 
within a defined equivalence range [-20% to + 20%]). 
The rates of treatment success for the Placebo and active treatment groups 
after 12 weeks of treatment are assumed to be approximately 
 and at 
least 
 respectively, in the mITT population. Using a 1:1 (active: 
placebo) randomization scheme, and assuming the conversion rate from 
mITT to PP population will be about 
 
 subjects in each treatment 
group (Test, Reference and Placebo) of the mITT population will provide at 
least 
 power to demonstrate superiority of active over Placebo at the 
 
significance level (p < 0.05, two-sided continuity-corrected Z-Tests and a 
pooled response rate for the standard error of the difference in proportions). 
Under the above assumptions, the overall study power to demonstrate 
therapeutic equivalence and superiority is estimated to be at least 
. To 
allow for approximately 
 of subjects who may drop out from the study 
or are otherwise non-evaluable, up to 855 subjects may be randomized to 
obtain 
 subjects in the mITT population (i.e., 
 per treatment arm).

8.0 INTRODUCTION 
8.1 Disease Being Treated 
Psoriasis is an immune (T-cell)-mediated inflammatory skin disease that affects approximately 2% of 
the western population.1 The most common type of psoriasis is plaque psoriasis, which is characterized 
by the presence of raised, thickened red lesions that are covered by silvery white scales, most commonly 
seen on the knees and/or elbows. Although there are reports implicating a genetic association with the 
disease, there are also studies that have established a set of psoriasis triggers including stress, 
medications (such as lithium, antimalarials, indomethacin, quinidine and beta blockers), injury or 
infection. The condition is considered chronic although the frequency and severity of outbreak in an 
individual can fluctuate without apparent cause.1-3 
Treatment of plaque psoriasis depends on the severity of the condition, previous treatment regimens 
and personal preference of the subject. For mild to moderate plaque psoriasis, topical treatments and 
phototherapy are the preferred treatment modalities. For more severe cases, oral or injectable systemic 
therapy may be warranted; however, the side effect profiles of these products limit their use. 
Psoriasis is typically described as mild, moderate or severe and by assessing the percentage of body 
surface area (BSA) affected and covered by psoriasis lesions. Several scale systems have been 
developed and many are in use in the clinical setting; however, a severity scale, despite being a 
convenient scoring system, does not capture the true burden of psoriasis for many patients. Psoriasis is 
associated with a broad range of medical and psychosocial comorbidities that erode quality of life of 
the patients. Subjects selected for this study suffer from plaque psoriasis of at least moderate severity 
and an IGA of 3 or more. 
8.2 Availability and Efficacy of Already Approved Therapies 
Treatment of plaque psoriasis depends on the severity of the condition, previous treatment regimens 
and personal preference of the subject. Psoriasis treatments historically include topical creams, sprays, 
lotions and foams. Examples of marketed products include corticosteroids (Topicort®, Clobex™), 
Vitamin A & D derivatives (Tazorac®, Dovonex®), NSAIDs (salicylic acid), etc. For more severe cases, 
systemic therapy (methotrexate, oral retinoids, UV light, biologics, etc.) may be warranted; however, 
the side effect profiles of these products limit their use.1,2,4-6 
Tazarotene is one of a class of drugs known as the acetylenic retinoids. Psoriasis is a chronic immune-
mediated disease that is characterized by the hyperproliferation and abnormal differentiation of 
keratinocytes and by inflammation. The epidermal changes associated with psoriasis may be due to the 
infiltration of inflammatory T lymphocytes and the release of cytokines in response to antigenic 
stimulation. Tazarotene is a retinoic acid receptor-specific retinoid with demonstrated efficacy in the 
topical treatment of psoriasis. Tazarotene down-regulates markers of keratinocyte differentiation, 
keratinocyte proliferation and inflammation. The drug also up-regulates three novel genes TIG-1 
(tazarotene-induced gene-1), TIG-2 and TIG-3, which may mediate an antiproliferative effect. The 
effect of tazarotene on these markers is probably a direct effect on gene expression rather than an 
indirect effect associated with disease improvement.

8.3 Scientific and Statistical Considerations 
Tazarotene has low systemic absorption and rapid elimination from semi-solid topical formulations 
of TAZORAC®. In a multiple-dose study with a once daily dose of tazarotene cream, 0.1% 
administered for 14 consecutive days to nine psoriatic subjects, mean peak plasma concentrations 
of 2.31 ng/mL occurring 8 hours after the final dose were observed for the active metabolite of 
tazarotene (tazarotenic acid).7 The 21 Code of Federal Regulations Sections 320.24 (Revised 
April 1, 2014) requires that in-vivo pharmacokinetic testing in humans is the preferred method in 
evaluating therapeutic equivalence. However, circumstances for which measurement of the active 
moieties in biological fluids is not possible or provides low concentrations, a pharmacodynamic 
response study indicative of clinical safety and efficacy can be considered.8-10 Based on the low 
systemic bioavailability of tazarotene from the topical cream product, a comparative clinical 
efficacy study is considered the most appropriate method to evaluate the therapeutic equivalence 
of two tazarotene topical cream, 0.05% formulations. 
 
 
 
 
 
 
 
8.4 Justification for use of Placebo 
A Placebo group is included to confirm the sensitivity of the study and minimize the possibility of 
a false positive result of therapeutic equivalence. Therefore, in addition to demonstrating 
therapeutic equivalence between Test and Reference products, both active products must show 
statistical superiority to the Placebo.11,12 
Eligible subjects will have a 33.33% chance of being randomized to Placebo (1:1:1 randomization 
scheme of Test: Reference: Placebo). 
 
 
 
 
 
 
 
 
8.5 Risks and Benefits 
The risks and benefits to subjects enrolled in clinical research studies that include a Placebo 
treatment group must be carefully considered based on three main criteria, namely: the disease 
being treated, the availability, efficacy and safety of approved therapies, and the scientific and 
statistical requirements of the desired outcome of the research study. The Office of Human Rights 
Protection (OHRP), a Division of the United States Federal Government’s Department of Health

Randomized subjects will be enrolled in the study for 85 ± 4 days. Although the potential for any 
drug-related side effects of significance occurring during the study is low, the risk is higher in the 
two active treatment groups than in the Placebo group. Topical application of Tazarotene can lead 
to drug-related effects, mainly affecting the application sites: skin itching, irritation, dryness and 
burning or pain sensation represent the most common side effects. 
All subjects enrolled in this study will receive Investigator evaluation of their condition over 85 
days. In addition, the subject will be paid for their participation, and any payments will be reviewed 
by the IRB and disclosed to the subject, via the informed consent form (ICF). 
9.0 STUDY OBJECTIVES 
The objectives of this study are to: 
1. Evaluate the therapeutic equivalence of the Test product, Tazarotene Cream 0.05% (Fougera 
Pharmaceuticals Inc.) to the Reference product, TAZORAC® (tazarotene) Cream, 0.05% 
(Allergan) in the treatment of stable plaque psoriasis. 
2. Demonstrate the superiority of the efficacy of the Test and Reference (active) products over that of 
Placebo in the treatment of stable plaque psoriasis. 
3. Compare the safety of the Test, Reference and Placebo products in the treatment of stable plaque 
psoriasis. 
10.0 INVESTIGATIONAL PLAN 
10.1 Study Design and Plan Description 
This multi-center, double-blind, randomized, vehicle-controlled, parallel-group, bioequivalence 
clinical study has been designed to evaluate the efficacy and safety of a generic tazarotene cream 0.05% 
(Fougera Pharmaceuticals Inc.) compared to the FDA Reference Listed Drug (RLD) TAZORAC® 
(tazarotene) Cream 0.05% (Allergan) in subjects with a clinical diagnosis of stable plaque psoriasis of 
at least moderate severity. Additionally, both the Test product and Reference (i.e., the RLD) products 
will be tested for superiority to a Placebo. Subjects with confirmed stable plaque psoriasis will apply 
the investigational product (IP) once daily, in the evening, to psoriatic lesions for 84 ± 4 days (12 
weeks). 
Before any study-specific procedures are performed, all subjects will read and sign the IRB-approved 
ICF. 
Each site will develop an individualized recruitment plan to collectively enroll approximately 855 
eligible subjects, 18 years of age and older, with a clinical diagnosis of stable plaque psoriasis and 
meeting the inclusion/exclusion criteria. Subjects will be randomized to one of the three IPs as follows: 
• 
Test: Tazarotene Cream, 0.05% (Fougera Pharmaceuticals Inc.) 
• 
Reference: TAZORAC® (tazarotene) Cream, 0.05% (Allergan, Inc.) 
• 
Placebo: Placebo (vehicle) Cream (Fougera Pharmaceuticals Inc.)

• 
Visit 3 - Interim Visit: Day 56 ± 4 days 
• 
Visit 4 - End of Study/Early Termination: Day 85 ± 4 days 
At Visit 1, eligible subjects will be randomized to the Test, Reference or Placebo product in a 1:1:1 
ratio using the 
 system, which is an interactive response technology (IRT) system provided 
by the IRT provider. Study subjects will be provided with 
 of IP. 
 may be 
dispensed to the subject at the discretion of the Investigator if the subject has a high BSA affected with 
plaque psoriasis at the time of dispensation that would warrant additional product. At Visit 2 and Visit 
3, subjects who continue to be eligible for continuation in the study can be dispensed 
 
, as needed based on the subject's current BSA affected and the amount of IP 
remaining from the tube(s) previously dispensed. Further, any empty tubes will be collected at these 
visits. At Visit 4, all tubes will be collected (used and unused). A subject may return for an Unscheduled 
Visit at any time, should they require a resupply of IP (i.e., tube lost; all IP used between visits). It is 
estimated that approximately  tubes, but up to  tubes may be needed to dose a subject with high BSA 
involvement (~20% BSA) for the treatment period (depending upon their treatment response over the 
12 weeks). Subjects with less BSA involvement will need significantly less IP (approximately  to  
tubes). 
The day that the subject administers their first dose of IP will be considered Day 1. 
 
 
 
 
For all other subjects, the first dose (Day 1) of IP 
will be applied on the evening of Visit 1. 
The subject will be instructed to apply enough cream (2 mg/cm2) to cover only the psoriatic lesions 
with a thin film (2 mg/cm2) once daily, in the evening, until the evening before Visit 4 (Day 85 ± 4 
days).There will be no application of the product on the day of the End of Study visit. 
Efficacy evaluations will be based on dermatological assessments in the clinic. The primary statistical 
analysis of interest is the (1) proportion of subjects with treatment success (defined as none, minimal 
or mild disease, a score of 0, 1 or 2, within the treatment area) on the Investigator’s Global Assessment 
(IGA) at the Week 12 visit. The secondary analyses are (1) proportion of subjects with disease severity 
at the Week 12 visit consistent with none or minimal, a score of 0 or 1, within the treatment area on the 
IGA, and (2) proportion of subjects with target site plaque elevation, scaling, and erythema scores of 
less than or equal to one on the PASI at the Week 12 visit.

Subjects who withdraw or are removed from the study will not be replaced. The Investigator may 
refer the subject for appropriate care if the subject withdraws due to safety concerns, as applicable. 
All subjects who are randomized will be included in the safety monitoring tabulating all AEs 
experienced after dosing until withdrawal from the study. 
10.3.5 Early Termination 
If a subject terminates from the study early, all efforts will be made to complete Visit 4 study 
procedures, obtain any outstanding data and collect all IP. For early termination, the Investigator 
shall fully document the reason for early termination and the date of removal. 
In the event that a subject discontinues from the study at any time due to an AE, the reason for 
discontinuation, the nature of the event and its clinical course must be fully documented. For such 
a subject, the Investigator should follow the subject until the AE has resolved, has become clinically 
insignificant, is stabilized, is confirmed to be ongoing at the end of the study, or the subject is lost 
to follow-up. Should a serious adverse event (SAE) be noted, procedures stated in section 10.7.4 
must be followed. Should pregnancy be noted, procedures stated in section 10.7.6 must be followed. 
Subjects who discontinue early because of lack of treatment effect after completing four weeks of 
treatment will be included in the per-protocol (PP) population as treatment failures provided they 
had no significant protocol deviations (PDs). Any PD that would compromise the integrity of the 
data will be considered significant. 
Subjects who discontinue early due to worsening condition and require alternate or supplemental 
therapy for the treatment of their plaque psoriasis during the study should be discontinued, included 
in the PP population analysis as treatment failures (provided they had no significant PDs during 
their time of study participation), and referred for effective treatment outside of the study. 
Subjects who discontinue early for reasons besides lack of treatment effect or worsening of 
condition should be excluded from the PP population, but included in the modified Intent-to-Treat

at least one dose of randomized IP and completed at least one post-dose evaluation.

10.4.1 Treatments Administration 
At Visit 1, eligible subjects will receive 
 of randomized IP (Test, Reference or 
Placebo). 
 may be dispensed to the subject at the discretion of the Investigator if the 
subject has a high BSA affected with plaque psoriasis at the time of dispensation that would warrant 
. Enough IP should be dispensed to allow the subject to dose daily until the next 
scheduled visit. 
At Visit 2 and Visit 3, subjects who continue to be eligible for continuation in the study can be 
dispensed 
, as needed based on the subject's current BSA and 
the amount of IP remaining from the tube(s) previously dispensed. Further, any empty tubes will 
be collected at these visits. At Visit 4, all tubes will be collected (used and unused). A subject may 
return for an Unscheduled Visit at any time, should they require a resupply of IP (i.e., tube lost; all 
IP used between visits; tube significantly damaged [became punctured]). 
The subject will be instructed on when to apply their first dose of IP, which will be considered Day 
1. Females of childbearing potential must administer their first dose (Day 1)
 
 
 
 For all other subjects, the first dose (Day 1) of IP will be applied 
on the evening of Visit 1. 
Subjects will be instructed to apply enough cream (2 mg/cm2) to cover only the lesions with a thin 
film. If a bath or shower is taken before application, the skin should be dry before applying the 
cream. Subjects will be instructed to apply the medication once daily, in the evening and to wash 
hands thoroughly before and after each application. The first dose will be applied on the evening 
of Day 1. The subject will then continue to apply a thin film (2 mg/cm2) of the product once daily, 
in the evening, to cover only psoriatic lesions until the evening before Visit 4 (Day 85 ± 4 days). 
The amount of IP required for each subject will vary greatly based on the subject's BSA affected 
with psoriasis at Baseline, as well as their rate of improvement or disease worsening over the course 
of the study. For subjects with BSA involvement close to 20% at Baseline, it is estimated that up 
to approximately 
 may be required for each subject to dose for the full 
duration of the study (84 days) depending upon their treatment response. Significantly less IP would 
be required for subjects with BSA involvement close to 2% (approximately
). Therefore, 
the amount of IP dispensed to each subject will be dependent upon their BSA involvement at 
Baseline and as the study progresses, at the discretion of the Investigator. Subject kits will each 
contain 
 of IP and will be randomized using the 
 system. After initial 
assignment of the first kit, additional kits of IP may be assigned to the subject as needed for dosing 
and/or to replace a missing tube and/or significantly damaged tube (i.e., punctured), also using the 
 system.

At each visit, the subject will be provided with a dosing diary in which they will be required to 
record the date of Day 1, all dosing dates and times and any missed doses. Each diary should be 
returned at the following visit so that the study staff may check compliance and file in the subject’s 
source documentation. 
10.4.2 Identity of IP 
The following products will be used in the study: 
• Test: Tazarotene Cream 0.05% (Fougera Pharmaceuticals Inc.) 
• Reference: TAZORAC® (tazarotene) Cream 0.05% (Allergan, Inc.) 
• Placebo: Placebo (vehicle) Cream (Fougera Pharmaceuticals Inc.) 
10.4.3 Study Blind 
The sponsor, clinical research organization (CRO), Investigator, staff at the study site, study 
monitors, and data analysis/management personnel will be blinded to the subject’s treatment 
assignment. The subject will be requested not to discuss the appearance of the IP tube with the 
Investigator or study staff outside of the 
. The tubes of Test, Reference and 
Placebo products will be blinded with identical outer cartons and labels. This will allow the study 
to be conducted under double-blind conditions (i.e., such that neither the subject nor the 
Investigator or study staff members will know the identity of the subject’s treatment). 
Each study site will have an 
 is blinded to the 
treatment arm that each subject has been randomized to. 
 
 
 
 
 
 
 
To ensure that information that could potentially bias handling of data is not disclosed, access to 
the master randomization code will be extremely limited. A sponsor representative who is not 
involved in clinical development or the study conduct will provide initial approval of the final code 
to 
 upon code generation. A member of the sponsor Pharmacovigilence department will have 
access to the code in case of a safety emergency and in order to expedite FDA reporting, if 
applicable. Otherwise, the packaging company 
 will hold the master 
randomization code until after database lock. No parties (CRO, clinical sites or sponsor) involved 
in the conduct of the study will have access to the master randomization code until after database 
lock. 
Breaking the blind must be considered only when knowledge of the treatment assignment is deemed 
essential by the Investigator for the subject's care. Whenever possible, if the Investigator feels that

At the conclusion of the study, after the database has been locked, each site will be sent a sealed 
envelope containing the full study randomization scheme that should be retained with the study 
documents in the event of an FDA Inspection. 
10.4.4 IP Shipment, Retention and Storage 
The IP will be shipped to each Investigator’s site from 
, a centralized 
distribution center. Upon receipt of the IP, the Principal Investigator (or designee), must 
immediately inventory the material and confirm receipt with the sponsor, per the instructions 
included in the shipment.

The Principal Investigator at each site will then ensure that all IP is stored in a locked, secure 
location, with access limited to the Investigator and his/her designee(s). 
 
 All IP will be stored at 20°C to 25°C 
(68°F to 77ºF), with excursions permitted from -5°C to 30°C (23ºF to 86ºF). The temperature of 
the storage location must be monitored on a daily basis and any excursion beyond the required 
temperature storage range should be reported to the sponsor. An accurate inventory of the IP over 
the course of the study (i.e., dispensed and returned) will be maintained in accordance with federal 
regulations. 
Initial supply quantities will be based on each site’s projected enrollment quantities. Resupply will 
be conducted as needed based on remaining in-house supply and continued enrollment projections. 
Multiple full blocks of IP will be included in every shipment to the Investigator. 
 
 
 
 
 
 
 
 
 
 
Once 
 has notified the site that they may return the IP, all unused tubes/kits and empty or 
partially used tubes/kits, other than those randomly selected for retention samples, will be returned 
to the sponsor (or designee). It is important that retention samples not be returned to 
 the 
sponsor or the packaging company during or at the end of the study. Sufficient IP must be retained 
among the sites participating in the study to meet the sample retention requirements as outlined by 
the FDA.16

10.5 Study Conduct 
10.5.1 Visit 1 (Day -14 to Day 1): Screening and Baseline Evaluation 
1. Informed Consent: Subjects who are willing to comply with study procedures will read, 
understand and sign the IRB-approved ICF. 
2. Medical History, Baseline Demographics and Concomitant Medications: Review the 
subject’s demographics and medical history including concomitant medication use within the 
last 6 months. 
3. Pregnancy Test: A urine pregnancy test will be required of all female subjects of childbearing 
potential before randomization. 
4. Vital Signs: Blood pressure, pulse, temperature and respiration rate will be recorded for each 
subject. In addition, height and weight will be measured to calculate total BSA. 
5. Application Site Reactions: A Medical Investigator (MD, DO, CRNP or PA) will grade the 
individual signs and symptoms. This will serve as a baseline for subsequent assessments of 
application site reactions. See Appendix C. 
6. Dermatologic Assessment: A Medical Investigator (MD, DO, CRNP or PA) will identify and 
measure the target lesion (the most severe lesion at the Baseline visit) and the location of the 
treatment area. The treatment area will be measured by assessing % BSA affected. 
7. Investigator’s Global Assessment: A Medical Investigator (MD, DO, CRNP or PA) will 
confirm the diagnosis of stable plaque psoriasis and perform a severity rating according to the 
IGA to determine the severity of the plaque psoriasis in the treatment area. See Appendix A. 
8. PASI Assessment: A Medical Investigator (MD, DO, CRNP or PA) will perform the PASI 
Assessment on the target lesion site. See Appendix B. 
9. Inclusion/Exclusion Criteria Review: Confirm the subject meets all inclusion criteria and 
none of the exclusion criteria.

10.6 Study Procedures 
10.6.1 Informed Consent 
At Visit 1, before performing any study-related procedures the study subject must sign the IRB-
approved ICF. The ICF will be reviewed and approved by an IRB before study commencement. 
No subject will be entered into the study without reading, understanding and signing an ICF. If the 
ICF is required in any other language besides English, translation will be performed by a certified 
translator and then approved by the IRB. 
10.6.2 Demographics 
At Visit 1, each subject shall be required to provide basic demographic information: date of birth, 
gender, ethnicity and race. 
10.6.3 Medical History 
At Visit 1 subjects will be questioned about their personal medical history, including psoriasis 
history. The medical history will include a complete review of all current diseases and their 
respective durations and treatments. 
10.6.4 Pregnancy Test 
All females of childbearing potential will have a urine pregnancy test performed at each visit. The 
test must be negative at Visit 1 for the subject to be eligible for inclusion in the study. If a subject 
has to wait for her menstrual period to start before applying the first dose of IP, the first dose of IP 
must be applied within 14 days of the negative Visit 1 pregnancy test. If the subject is female and 
not considered of childbearing potential, then the reason must be documented in the subject’s 
source document. 
Any subject who becomes pregnant during the study should be discontinued and Early Termination 
procedures (Visit 4 procedures) completed. Pregnancy reporting procedures should be followed, as 
outlined in section 10.7.6. The outcome of the pregnancy should be followed by the Investigator to 
the conclusion of the pregnancy (i.e., birth, termination or miscarriage). The pregnancy will be 
reported as an AE from the time of first IP dose. 
10.6.5 Vital Signs 
The subject’s vital signs will be recorded (blood pressure, pulse, temperature, and respiration rate) 
at Visits 1 and 4. At Visit 1, height and weight will also be measured to calculate BSA.

10.6.6 Concomitant Medication 
At Visit 1, subjects will be questioned about current and prior concomitant medication use over the 
6 months before the Baseline visit. Subjects will also be questioned about ongoing or new 
concomitant medication use during the treatment period at Visits 2, 3 and 4. The medications to be 
recorded will include prescription and OTC medications and dietary supplements. 
At Visits 2 and 3, any subject who has used medications restricted by the protocol may be 
discontinued from the study. If discontinued, all Early Termination procedures (Visit 4 procedures) 
should be performed. 
10.6.7 Dermatologic Assessment 
At Visit 1, the Medical Investigator (MD, DO, CRNP or PA) will assess the subject’s plaque 
psoriasis and calculate the % BSA involvement using the subject’s hand (palm plus extended 
fingers) as an estimate of 1% BSA. For inclusion in the study, % BSA affected must be at least 2% 
but no more than 20%. The Investigator will then identify and measure the size of the treatment 
area and identify the most severe psoriasis lesion within the treatment area. This lesion will be 
designated as the target lesion. 
10.6.8 IGA 
At Visit 1, a Medical Investigator (MD, DO, CRNP or PA) should document a confirmed diagnosis 
of stable plaque psoriasis. 
At each visit, a Medical Investigator will perform a psoriasis severity rating according to the IGA 
(see Appendix A). At Visit 1, the IGA must be a score of 3, 4 or 5 for the subject to be eligible for 
inclusion. At Visit 4 (or Early Termination), the IGA score will be used to determine Treatment 
Success or Treatment Failure for the primary endpoint, with treatment success defined as none, 
minimal or mild disease, a score of 0, 1 or 2 within the treatment area. Further, at Visit 4 (or Early 
Termination), the IGA score will be used to evaluate the secondary endpoint, which is the 
proportion of subjects with disease severity consistent with none or minimal, a score of 0 or 1, 
within the treatment area. 
 
The IGA is a static scale and no reference to previous scores for the subject should be made during 
this assessment. 
10.6.9 PASI 
At Visit 1, a Medical Investigator (MD, DO, CRNP or PA) will identify the most severe lesion, and 
this will be designated the target lesion. 
At each visit, a Medical Investigator will perform the PASI at the target lesion site according to the 
PASI scale (see Appendix B). At Visit 1, the PASI score for plaque elevation at the target lesion 
must be a 3, 4 or 5 for the subject to be eligible for inclusion. At Visit 4 (or Early Termination), the 
PASI score will be used to evaluate the secondary endpoint, which is the proportion of subjects 
with target site plaque elevation, scaling and erythema scores of less than or equal to 1.

10.6.10 Application Site Reactions 
At Visit 1, the Investigator will grade the individual signs and symptoms per Appendix C. This will 
serve as a baseline for subsequent assessments of application site reactions. At Visits 2, 3 and 4, 
the Investigator will evaluate the subject for local application site reactions (erythema, dryness, 
burning/stinging, erosion, edema, pain, and itching) based on the scale provided in Appendix C. 
Reactions will be documented in source documents for each subject. 
10.6.11 Inclusion and Exclusion Criteria Review 
At Visit 1, the site will confirm that the subject meets all inclusion criteria and none of the 
exclusion criteria. If the subject does, they are eligible for enrollment in the study and will be 
randomized to a treatment group. If the subject does not, their participation will be complete and 
they will be discontinued as a screen failure. 
10.6.12 Randomization 
At Visit 1, eligible subjects selected for enrollment will be assigned a randomization number 
using 
. The system will allocate a kit box of IP to the subject in a double-blind fashion. 
The kit box will contain 
 of product for a single treatment arm (Test, Reference or 
Placebo). 
10.6.13 Dispensing IP 
An 
 will dispense an initial supply of IP at Visit 1, and will resupply the 
subject at Visit 2 and/or 3 or an Unscheduled Visit, as needed. The amount of IP dispensed is at the 
discretion of the Investigator based on the amount of BSA affected with psoriasis. After the initial 
 of IP have been dispensed and fully used and/or the tube has become lost or significantly 
damaged (i.e., became punctured), an additional kit box(s) of the same treatment group may be 
allocated to the subject using

 will review the previously dispensed IP. If a tube is 
empty, it will be collected from the subject. If a tube still contains significant product, the tube will 
be re-dispensed to the subject. At Visit 4, all used and unused tubes will be collected. The 
 will ensure that all Drug Dispensing Logs are completed correctly. Any

10.6.15 Subject Dosing Instructions and Diary 
Subjects will be instructed to use the IP as described in section 10.4.1. 
The site will instruct the subject on when the first dose of IP will be applied, which will be 
considered Day 1. The subject will record the date of Day 1 in their diary. 
 
 
 
 
For all other subjects, the first dose (Day 1) of IP will be applied on the evening of Visit 1. 
Subjects will be provided with a diary at Visits 1, 2 and 3. Subjects will be asked to record the date 
of Day 1, the time and date of each dose, any missed doses, any AEs that have occurred and any 
concomitant medications utilized throughout the study. The site will review the diary and evaluate 
the subject’s compliance with the protocol at Visits 2, 3 and 4, based on any new additions to their 
medical history, new or changed concomitant medications, AEs and dosing compliance. If the diary 
is not returned, the staff will collect available information based on discussion with the subject. 
The subject will also be reminded of the medications and/or treatments that are prohibited during 
the study. 
If the subject is no longer eligible for participation at Visit 2 and/or 3, the site will conduct Early 
Termination (Visit 4) procedures. 
10.6.16 Standardized Sunscreen 
Along with the IP at Visit 1, the subject will be provided with standardized sunscreen (Neutrogena 
Ultra Sheer or similar) for use when needed. The use of the sunscreen should be documented on 
the concomitant medication page on the source documents and eCRFs. If additional sunscreen is 
needed during the study, additional sunscreen can be dispensed at Visit 2 and/or Visit 3 or an 
Unscheduled Visit. 
10.6.17 Health Status/AEs 
At Visits 2, 3 and 4 subjects will be questioned regarding any changes in their medical status since 
their previous visit. Any significant health changes observed after signing of the ICF into the study 
will be reported as AEs, as deemed appropriate by the Investigator. 
10.7 AEs/SAEs 
The subjects will be monitored throughout the study for any AEs. AEs will be collected through both 
solicited and unsolicited means and subsequently coded in tabular form using the MedDRA® (Version 
18.1 or higher) Adverse Event Dictionary. The subjects will be requested to report signs, symptoms 
and any changes in health to the clinic staff. Observed changes during the dermatology exam and/or 
clinical assessment at each visit (i.e., changes in the application site reaction) should be assessed by the 
Investigator to determine (in their opinion) if the change should be reported as an AE or not. Severity

of each AE will be determined by the staff based on observation and questioning of the subjects. The 
Investigator will judge the relationship of the event to the study treatments. 
10.7.1 Definitions 
An Adverse Event / Experience is any untoward medical occurrence in a subject administered a 
pharmaceutical product and which does not necessarily have to have a causal relationship with this 
treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding, for example), symptom or disease temporally associated with the use of a 
medicinal product, whether or not considered related to the medicinal product. 
An SAE is any untoward medical occurrence that at any dose: 
• 
results in death 
• 
is life-threatening 
• 
requires inpatient hospitalization or prolongation of existing inpatient hospitalization 
• 
results in persistent or significant disability / incapacity 
• 
is a congenital anomaly / birth defect 
• 
is medically significant: Medical and scientific judgment should be exercised in deciding 
whether expedited reporting is appropriate in other situations, such as important medical 
events that may not be immediately life-threatening or result in death or hospitalization but 
may jeopardize the subject or may require intervention to prevent one of the other outcomes 
listed above. These should also usually be considered serious. 
These characteristics/consequences have to be considered at the time of the event. For example, 
regarding a life- threatening event, this refers to an event in which the subject was at risk of death 
at the time of the event; it does not refer to an event which hypothetically might have caused death 
if it were more severe. 
An Adverse Drug Reaction (ADR) is any AE for which the Investigator or sponsor assess a 
reasonable possibility for a causal relationship to a medicinal product, see 10.7.3 below. 
An Unexpected Adverse Reactions is defined as an ADR, the nature or severity of which is not 
consistent with the Reference Safety Information (Appendix D). The term ‘severity’ is used here 
to describe the intensity of a specific event. This has to be distinguished from the term ‘serious’. 
Reports which add significant information on the specificity, increase of occurrence or severity of 
a known, already documented serious adverse reaction constitute unexpected events. 
Information about common side effects already known about the IP can be found in the Reference 
Safety Information (Appendix D) or will be communicated in the form of Investigator 
Notifications. These common side effects are also listed in the informed consent. The common side 
effects will be discussed with the subject prior to their signing of the informed consent. 
For further details, please refer to the “Quick Reference Guide for Completing the SAE Form” for 
completing the “Serious Adverse Event Report Form” (Novartis form).

10.7.2 Severity of AEs 
The term ‘severity’ is used here to describe the intensity of a specific event. This has to be 
distinguished from the term ‘serious’. In the course of the study, the Investigator will determine 
whether any AE’s have occurred and will grade their severity as follows: 
Mild: 
Transient or mild discomfort (< 48 hours); no medical intervention/therapy 
required 
Moderate: 
Mild to moderate limitation in activity - some assistance may be needed; no 
or minimal medical intervention/therapy required 
Severe: 
Marked limitation in activity, some assistance usually required; medical 
intervention/therapy required, hospitalization possible 
10.7.3 Relationship to the IP 
The Investigator should evaluate all AEs considering all accessible data, at any time new 
information becomes available. The definition of IP includes the Test product under evaluation and 
the Reference product or Placebo that is given during any phase of the study. 
The Investigator should assess whether or not, in his/her expert opinion, the AE is suspected to the 
drug according to the following considerations: 
Suspected: 
The temporal relationship of the clinical event to study treatment 
administration makes a causal relationship possible, and other 
drugs, therapeutic interventions or underlying conditions do not 
provide a sufficient explanation for the observed event. 
Not suspected: 
The temporal relationship of the clinical event to study treatment 
administration makes a causal relationship unlikely, or other drugs, 
therapeutic interventions or underlying conditions provide a sufficient 
explanation for the observed event. 
Causality assessments are critical and must be provided for each unique AE in relation to each IP. 
Missing causality assessments will be handled as suspected to IP by the sponsor. 
10.7.4 AE Documentation 
Any AE (non-serious and serious) occurring after the subject has provided study-specific informed 
consent, and until the last study visit of the subject, has to be recorded on the AE pages of the eCRF. 
The occurrence of AEs should be sought by non-directive questioning of the subject at each visit 
during the study. AEs also may be identified when they are volunteered by the subject during or 
between visits or during physical examination, laboratory test or other assessments. All AEs should 
be given appropriate medical care. Treatment may include one or more of the following: no action 
taken (i.e., further observation only); IP dosage adjusted/temporarily interrupted; IP permanently 
discontinued due to this AE; concomitant medication given; non-drug therapy given, subject 
hospitalized / subject’s hospitalization prolonged. The treatment of the AE should be documented 
in the eCRF. In addition, the action taken with the IP should be documented, and should be assigned 
to one of the following categories: not changed, withdrawn, reduced, increased, interrupted,

unknown and not applicable. Concomitant medication, other treatments or changes in the 
administration of the IP should be specified and documented. 
Medical conditions/diseases present before starting IP are only considered AEs if they worsen after 
enrollment. Abnormal laboratory values or test results constitute AEs only if they induce clinical 
signs or symptoms, are considered clinically significant or require therapy. 
Once an AE is identified, the Investigator should follow-up as specified below. Each time, the 
outcome should be documented and assigned to one of the following categories: not 
recovered/unchanged, 
condition 
deteriorating, 
recovered/resolved, 
improving/recovering, 
recovered/resolved with sequelae, fatal or unknown. The assessment of an AE should be made at 
each planned visit (or more frequently, if necessary). The Investigator should document in the 
eCRF any changes in seriousness, severity, the suspected relationship with the IP, the interventions 
required to treat it, and the outcome. 
AEs occurring between informed consent and first dosing 
Any AE occurring between study-specific informed consent and first dosing will be documented 
as “screening event”, with a IP causality assessment “IP not yet administered”. 
AEs occurring after first dosing 
The Investigator should follow all AEs which occurred from first dosing and during the course of 
the study to the last visit of the subject until the AE has resolved or stabilized or the subject has 
been lost to follow-up. 
Ongoing SAEs at the time of last visit 
For any SAEs still ongoing at the time of last visit, the Investigator should continue to follow-up 
until the SAE has resolved or has stabilized / is judged permanent, for SAEs considered to be related 
to IP (serious adverse drug reaction [SADR]), and for up to 30 days after the last visit of subject 
for non-related SAEs. The Investigator should send SAE follow-up reports to recipients as per the 
‘SAE Reporting’ section 10.7.5 below. 
SAEs occurring after the last visit 
At the last visit, the Investigator should instruct each subject to report any new SAE (beyond the 
protocol observation period) that the subject, believes might reasonably be related to study 
treatment. The Investigator must report the SADR to recipients as per the ‘SAE Reporting’ section 
10.7.5 below. 
10.7.5 SAE Reporting 
It is vitally important that the Investigator reports immediately, (i.e., no later than 24 hours 
after awareness), any SAEs or updates to previously reported SAEs, even if the Investigator does 
not consider the AE to be drug-related. 
The Investigator should send SAE reports on the “Serious Adverse Event Report Form” (Novartis 
form), as initial or follow-up reports, via fax or email to the Local Person for Pharmacovigilence 
(LPPV) (listed below), and in copy to the responsible Medical Monitor/CRO Contact and the 
sponsor (listed below), to the email addresses provided in the table below.

The Investigator should also send all updates / new information on a new SAE Report Form as a 
follow-up to the previously reported SAE. The follow-up information should describe whether the 
event has resolved or continues, if a diagnosis is available, if and how it was treated, and whether 
the subject continued or withdrew from study participation. 
Recurrent episodes, complications or progression of the initial SAE must be reported as follow-up 
to the original episode, regardless of when the event occurs. 
Any new SAE (that is considered completely independent of a previously reported SAE) should be 
reported as a new and separate initial SAE report. 
Any queries from the LPPV, CRO or sponsor regarding SAE reports should be answered by the 
Investigator within 24 hours. 
For more detailed information refer to the “Quick Reference Guide for Completing the SAE Form”. 
The Investigator should retain a delivery notification for all recipients in the Investigator study file.

Investigator Notification 
If an ADR is not listed in the Reference Safety Information (e.g., Package Insert), the sponsor may 
urgently require further information from the Investigator for Health Authority reporting. 
The sponsor may, if applicable, issue Investigator Notifications of unlisted SADRs (Suspected 
Unexpected Serious Adverse Reactions [SUSARs]) to all Investigators concerned with any study 
with the same IP. 
The submission of these Investigator Notifications, if applicable, to IRBs is the responsibility of 
the Investigator or the CRO as stipulated in the study contract. 
Health Authority Reporting 
The sponsor will submit all reportable cases within the requested timelines to all concerned 
authorities. 
Under 21 CFR 320.31(d)(3), the sponsor or CRO must inform other Investigators involved in the 
study plus the FDA within 15 days of becoming aware of the occurrence of the SAEs. When a 
serious AE is death, sponsor or CRO must inform other Investigators involved in the study plus the 
FDA within 7 days of becoming aware of the event. SAEs that occur with the Test, Reference or 
Placebo product must be reported. 
IRB Reporting 
AEs that are evaluated by the Investigator as "Serious" should be reported by the Investigator to 
the sponsor and CRO within 24 hours, and the IRB as soon as is practically possible, preferably 
within 24 hours, whether or not they are considered expected or drug-related.

its commencement during a normal menstrual period, is of paramount importance. The Investigator 
must report any cases of pregnancy of subjects in the course of a study immediately (within 24 
hours) of awareness to the LPPV and with copy to the responsible Medical Monitor/CRO Contact 
and the sponsor, to the email addresses provided in the table above, as described in section 10.7.5. 
 
 
The Investigator should immediately withdraw the subject from the study, and should follow-up 
each case of pregnancy through the expected delivery date, and report the outcome, including 
spontaneous or voluntary termination, details of the birth and any birth defects, congenital 
abnormalities, or maternal and/or newborn complications. 
 
 
 
 
 
10.7.7 Quality Complaints 
In case of quality complaints (technical or transport complaints), the Investigator within 24 hours 
of learning of its occurrence informs the Medical Monitor/CRO Contact and the sponsor via the 
email addresses provided in the table above in section 10.7.5. Reporting should include all details 
relevant to the quality complaint. The monitor/CRO Contact and/or sponsor may reach out to the 
site for further detail. Any queries from the CRO or sponsor regarding quality complaints should 
be answered by the Investigator within 24 hours. The Investigator should document the quality 
complaint in the subject's source document (for subject's specific quality complaints) and/or the 
Investigator's study file (for site specific quality complaints), as applicable. 
Any AE associated with a quality complaint needs to be documented and reported in addition by 
the Investigator as described in section 10.7.4 and 10.7.5.

10.7.9 Reconciliation 
Reconciliation between the safety database of the sponsor and the clinical database at the CRO will 
be done periodically and at the end of the study by comparing line listings from the safety database 
with the data in the clinical database. 
The eCRFs / the clinical database will be reviewed for potentially unreported cases. For any 
reportable case, the following parameters need to match exactly between the clinical and the safety 
database: trial number, site number, subject identification number, investigational drug, 
seriousness, date of death (if applicable) and Investigator causality. All other parameters only need 
to be plausibly and medically consistent. For any SAE assessed as suspected, a more detailed 
reconciliation should be conducted, including also treatment dates and medical history. 
11.0 STATISTICAL METHODS 
11.1 Statistical Plan 
A Statistical Analysis Plan (SAP), including study data report format, detailing the intended statistical 
analysis of the study data, will be prepared as a separate document and finalized before database lock. 
Any deviation from the original statistical plan will be described and justified in the final report, as 
appropriate. The procedure for accounting for missing, unused and spurious data will be included in 
the SAP. 
If not otherwise specified, statistical significance is defined as p < 0.05, two-sided. Data will be 
summarized with respect to demographic and baseline characteristics, efficacy variables and safety 
variables.

All statistical analysis will be conducted using SAS®, Version 9.4 or higher. Datasets will be prepared 
using headings from Clinical Data Interchange Consortium (CDISC), Study Data Tabulation Model 
(SDTM) implementation for human clinical trials, and Analysis Dataset Model (ADaM). 
11.2 Sample Size Determination 
Sample size calculations were performed using 
 For the primary endpoint 
analysis, the rate of treatment success for the Reference treatment after 12 weeks of treatment is 
expected to be approximately 
 in the PP population. Assuming that the rates of treatment success 
for Test and Reference treatments are the same, a sample size of 
 subjects in each active group in 
the PP population will provide approximately 
 power to demonstrate therapeutic equivalence (i.e., 
the 90% confidence interval (Yates’ continuity-corrected) of the absolute difference between the Test 
and Reference rates of treatment success is within a defined equivalence range [-20% to + 20%]). 
The rates of treatment success for the Placebo and active treatment groups after 12 weeks of treatment 
are assumed to be approximately 
 and at least 
 respectively, in the mITT population. Using a 
1:1 (active: placebo) randomization scheme, and assuming the conversion rate from mITT to PP 
population will be about 
 subjects in each treatment group (Test, Reference and Placebo) of 
the mITT population will provide at least 
 power to demonstrate superiority of active over Placebo 
at the 5% significance level (p < 0.05, two-sided continuity-corrected Z-Tests and a pooled response 
rate for the standard error of the difference in proportions). 
Under the above assumptions, the overall study power to demonstrate therapeutic equivalence and 
superiority is estimated to be at least 
 To allow for approximately 
 of subjects who may drop 
out from the study or are otherwise non-evaluable, up to 855 subjects may be randomized to obtain 
 
subjects in the mITT population (i.e., 
 per treatment arm). 
11.3 Study Populations 
11.3.1 PP Population 
The PP population will include subjects that comply with the protocol as follows: 
• 
All randomized subjects who meet all inclusion and exclusion criteria.

comparisons will be presented using Chi-Square or Cochran-Mantel-Haenszel tests for the categorical 
variables, and analysis of variance (ANOVA) for the continuous variables. 
All data will be listed by treatment and subject. 
11.5 Efficacy Endpoints 
Primary Efficacy Endpoint 
Proportion of subjects with treatment success (defined as none, minimal or mild disease, a score of 0, 
1 or 2 within the treatment area) on the IGA at the Week 12 visit (Day 85 ± 4 days, End of Study). 
Secondary Efficacy Endpoints 
1. Proportion of subjects with disease severity at the Week 12 visit (Day 85 ± 4 days, End of 
Study) consistent with none or minimal, a score of 0 or 1, within the treatment area on the IGA, 
AND 
2. Proportion of subjects with target site plaque elevation, scaling and erythema scores of less 
than or equal to 1 on the PASI at the Week 12 visit (Day 85 ± 4, End of Study). 
11.6 Primary and Secondary Endpoint Analyses 
Therapeutic Equivalence Analysis 
Therapeutic equivalence will be evaluated for both primary and secondary endpoints using the PP 
population, with results in the mITT population being supportive. For the dichotomized primary 
endpoint (proportion of treatment success), if the 90% confidence interval (with Yates’ Correction 
Factor) of the difference between the proportion of subjects considered a “treatment success” in the 
Test and the Reference treatment groups at Week 12 is contained within the pre-defined equivalence 
limits [-20%, +20%], then therapeutic equivalence will be considered to have been supported for the 
endpoint. The same statistical approach will be conducted for analysis of the two dichotomized 
secondary endpoints in the PP and mITT populations. 
To declare therapeutic equivalence of the Test product to the Reference product, therapeutic 
equivalence must be demonstrated for only the primary endpoint in the PP population. 
Superiority to Placebo Analysis 
The primary measure of superiority will be evaluated using the mITT population and LOCF for missing 
efficacy values. The results in the PP population will be considered supportive. The superiority of the 
Test and Reference products over Placebo will be concluded for the primary endpoint if the proportion 
of treatment success at Week 12 is statistically superior to Placebo (p < 0.05, two-sided a Cochran-
Mantel-Haenszel exact test stratified by clinical site) using the mITT population and LOCF. The same 
statistical approach will be conducted for analysis of the two dichotomized secondary endpoints in the 
mITT and PP populations. 
To declare superiority of the Test and Reference products over Placebo, their superiority must be 
demonstrated for only the primary endpoint in the mITT population.

11.7 Treatment-by-Site Interaction and Pooling of Clinical Sites 
As this is a multiple-site study, the interaction of treatment-by-site may be evaluated by the Cochran-
Mantel-Haenszel test (stratified by site) at the 5% significance level (p < 0.05, 2-sided) for the primary 
efficacy endpoint in both the PP population (for equivalence testing) and mITT population (for 
superiority testing). 
 
 
 
 
 
 This will include examination of responder rates at each site where 
sample sizes per treatment may be influential in the assessment of the interaction. 
11.8 Safety Analysis 
AEs will be classified using standard MedDRA terminology Version 18.1 or higher and summarized 
by treatment group. Summary tables comparing the type, date of onset, date of resolution, incidence, 
severity, relationship to the IP, outcome and action taken will be prepared by treatment group. Should 
sufficient data exist, AE frequencies will be compared among treatments using Fisher’s exact test or a 
similar test. 
Application site reactions (erythema, dryness, burning/stinging, erosion, edema, pain, itching) recorded 
at each visit will be compared among treatment groups. A descriptive analysis comparing the 
application site reactions for each treatment group will be created. 
Concomitant medication use during the treatment period will be tabulated by subject. 
Signs and symptoms of psoriasis will not be considered AEs, unless in the Investigator’s opinion, they 
have increased in frequency and/or severity to such an extent that the Investigator/subject considers 
that it is in the subject’s best interest to be dropped from continued participation in the study and given 
alternative therapy for their condition. 
All randomized subjects who received IP will be included in the comparative safety analysis. 
12.0 REGULATORY OBLIGATIONS 
12.1 Institutional Review Board

or after completion of the study. SAEs must also be reported to the IRB per their policy; however, the 
Investigator/CRO is encouraged to report all SAEs to the IRB as soon as practically possible, preferably 
within 24 hours, even if the IRB’s reporting requirement is longer. 
Periodic status reports must be submitted to the IRB per their policy, but at least annually, as well as 
notification of study completion or termination with a final report within one (1) month after close out. 
A copy of all reports submitted to the IRB must be sent to the sponsor. 
The Investigator will ensure that an IRB that complies with the requirements set forth in Part 56 (Title 
21 Code of Federal Regulations) will be responsible for the initial and continuing review and approval 
of the proposed clinical study. 
12.2 Subject Confidentiality 
All applicable Investigators and study staff must comply with the federal medical Privacy Rule 
authorized by the HIPAA), which requires most health care providers to take new measures to protect 
the privacy of individually identifiable health information. The Privacy Rule’s requirements extend to 
identifiable health information used or disclosed in research. The HIPAA Privacy Rule reinforces 
clinical Investigators’ existing obligations to protect the privacy of identifiable health information under 
state law, codes of medical ethics and the federal regulations governing research. 
Also, in compliance with federal guidelines regarding the monitoring of clinical studies and in 
fulfillment of his/her obligations to the sponsor, it is required that the Investigator permit the study 
monitor, sponsor auditor, and/or FDA representative to review that portion of the subject’s medical 
record that is directly related to the study. This shall include all study relevant documentation including 
subject medical histories to verify eligibility, admission/discharge summaries for hospital stays 
occurring while the subject is enrolled in the study and autopsy reports for deaths occurring during the 
study. 
As part of the required content of informed consent, the subjects must be informed that his/her medical 
chart may be reviewed by the sponsor, the sponsor’s authorized representatives or FDA. Should access 
to the medical record require a separate waiver or authorization, it is the Investigator’s responsibility to 
obtain such permission from the subject in writing before the subject is entered into the study. 
12.3 Study Documentation 
This study will be conducted in compliance with the protocol; Good Clinical Practices (GCP) and all 
applicable regulations, including the Federal Food, Drug and Cosmetics Act, US applicable Code of 
Federal Regulations (title 21), parts 50, 56, 312, 320, and any IRB requirements relative to clinical 
studies; and the Declaration of Helsinki, June 1964, as modified by the 64th World Medical Association

12.3.2 Informed Consent 
An ICF that includes all of the relevant elements currently required by FDA and local state 
regulations will be provided to each prospective study subject before being screened into the study. 
The type and method of study, tests to be administered, any potential or possible hazards, and the 
subject’s right to withdraw from the study at any time will be explained to the subjects by the 
Investigator or designee. Once the Investigator or designee is assured that an individual candidate 
understands the implications of participating in this study, the subject will be asked to give consent 
by signing and dating in the appropriate areas of the ICF. The Investigator or designee will also 
sign and date the form, along with a staff member who will sign the ICF as a witness to verify that 
the subject has indeed received information. If any other language is required, translation will be 
performed by a certified translator and will be IRB-approved. A copy of the ICF will be provided 
to the subject. A notation will be made in the subject’s medical record indicating the date informed 
consent was obtained. 
12.3.3 Protocol and Informed Consent Changes 
The procedures defined in the protocol will be carefully reviewed to ensure that all parties involved 
with the study fully understand the protocol. Sponsor approved changes to the protocol or the ICF 
will be implemented as revisions to the original documents and will require additional review and 
approval by the IRB. Revisions to the original protocol will be documented in amendments, 
incorporated as a preface to the new version. Any revision that substantially alters the study design 
or increases potential risk to the subject requires the subject’s consent to continue in the study. The 
approvals will be processed in accordance with the established IRB procedures. Copies of all 
protocol and ICF amendments/revisions, along with letters noting IRB approval, will be submitted 
to the sponsor. 
The only circumstance in which a protocol amendment may be initiated without prior IRB approval 
is to eliminate apparent immediate hazards to a subject or subjects. However, the Investigator must 
notify the IRB immediately, no later than within five (5) working days after implementation. 
12.3.4 Source Documents and Case Report Forms 
All subjects will be identified by initials and date of birth. Randomized subjects will also have a 
unique subject randomization number. Source documents will be used to record all study-related 
data. Source document entries will be used to complete eCRFs which will record all critical study 
information. A set of eCRFs will be completed for each subject enrolled in the study. All data from 
eCRFs will be reviewed, evaluated and signed by the Investigator, as required. All eCRFs will be 
cross referenced to source documentation by the study monitor and/or the sponsor to ensure 
accurate transcription of the data. 
The original source documents and a copy of the corresponding eCRFs (electronic or print out) will 
be retained by the Investigator. Subjects who terminate early from the study will have the Visit 4

Details will be provided in the monitoring plan. 
12.3.5 Drug Accountability 
All IP receipt, inventory, selection of retention, dispensing, dosing and reconciliation records will 
be maintained in compliance with federal regulations. The IP will be dispensed to qualified study 
subjects according to established procedures. Drug accountability will be maintained by the site 
throughout the study, and will be reviewed by the monitor throughout the study. At the end of the 
study (i.e., at the Site’s Close Out visit) all used and unused IP, with the exception of required 
retention samples, will have a documented inventory conducted and will be returned to sponsor or 
designee. 
12.3.6 Drug Storage 
All IP will be stored at 20°C to 25°C (68°F to 77ºF), with excursions permitted from -5°C to 30°C 
(23ºF to 86ºF). IP should be stored in a secure place with limited access by authorized individuals 
only. The Investigator will be responsible for maintaining accurate records of IP receipt, retention, 
dispensing and return. 
12.3.7 Retention of Reserve Samples 
For every IP shipment received at the Investigator site, the Investigator (or designee) will randomly 
select one block of IP for retention. As per the Code of Federal Regulations Part 21, Section 
320.38(e), “Each reserve sample shall be stored under conditions consistent with the product 
labeling and in an area segregated from the area where testing is conducted and with access limited 
to authorized personnel. Each reserve sample shall be retained for a period of at least 5 years 
following the date on which the application or supplemental application is approved, or, if such 
application or supplemental application is not approved, at least 5 years following the date of 
completion of the bioavailability study in which the sample from which the reserve sample was 
obtained was used.”

of retention samples are retained as per sponsor requirement. 
 
The number of each kit 
box in the block selected for retention will be noted on the drug accountability form as a retention 
sample, in addition to the retention sample log and sponsor supplied acknowledgment. These blocks 
will be affixed with a label provided by 
 to be clearly marked as retention samples and are 
not to be used for dispensing to study subjects. Retention samples should not be returned to the 
sponsor at any time. At the completion of the retention period, the Investigator must contact the 
sponsor if they wish to destroy the retention samples. If destruction is authorized, the sponsor must 
supply this directive to the Investigator in writing.

12.3.9 Pregnancy and Breastfeeding 
Tazarotene cream is designated as Pregnancy Category X; therefore there is a potential risk of 
teratogenicity. Therefore, all females of childbearing potential should be maintained on an 
appropriate method of contraception throughout the study to prevent pregnancy. Females that are 
lactating, breastfeeding or trying to become pregnant should not be enrolled in the study. The ICF 
will clearly outline the risk and this requirement. 
All females of childbearing potential will have a pregnancy test performed at each clinic visit. The 
pregnancy test will have a minimum sensitivity of at least 50 mIU/ml for hCG. The results of all 
pregnancy tests (positive or negative) will be documented. A negative urine pregnancy result must 
be obtained at screening (Visit 1) before study participation. Subjects with a positive pregnancy 
result during screening will not be enrolled in the study. Before study enrollment, females of 
childbearing potential must be advised of the importance of avoiding pregnancy during study 
participation.

Regulations require the Investigator must retain all records according to 21 CFR 312.62(c) for a 
period of 2 years following the date the marketing application is approved for the IP for the 
indication for which it is being investigated; or, if no application is to be filed or if the application 
is not approved for such indication, until 2 years after the investigation is discontinued and FDA is 
notified. However, Fougera requires the Investigator retain all records for a period of 
 after 
termination of the study unless CRO or sponsor authorizes, in writing, earlier destruction. No 
documents shall be transferred from the site (i.e., to an off-site storage facility) without first 
notifying the sponsor. No documents shall be destroyed without the sponsor's written approval. If 
the Investigator can no longer support the retention of the records (i.e., due to retirement or death), 
the documents must be transferred to a new responsible party. The sponsor must be notified of this 
transfer in writing. 
12.3.12 Study Monitoring and Auditing 
Monitoring and Auditing by the CRO 
 will be responsible for monitoring the study according to GCP and applicable regulations. 
Monitoring visits are for the purpose of training, confirming adherence to the protocol and to verify 
complete and accurate data collection. A monitoring plan will be agreed upon between the sponsor 
and the CRO. The Investigator will be visited by a monitor before the study, at regular intervals 
during the course of the study and at the completion of the study. Investigator audits will also be 
conducted, the details of which would be described in a separate audit plan. Site Monitoring visits 
and audits (as applicable) will be scheduled with the Investigator in advance of the visit at a 
mutually agreed time.

The study monitor will review the ICFs and verify eCRF entries by comparing them with the source 
documents. The monitor will review the maintenance of regulatory documentation and IP 
accountability. The monitor will review the progress of the study on a regular basis with the 
Investigator and other site personnel. The clinical site will make all records associated with the 
study available to 
 representative during such monitoring visits and audits. It is the 
Investigator’s responsibility to: 
• 
Provide the monitor with sufficient time to review the eCRFs and relevant source 
documents 
• 
Be available to answer questions and/or resolve data clarifications and/or implement 
corrective and preventative actions (as required following a site audit) 
• 
Provide adequate time and space for these visits

Audit by the Sponsor and/or Regulatory Authorities 
The study may be subject to audit by the sponsor, sponsor representative, the IRB or by regulatory 
authorities. The sponsor will schedule any audits in advance of the visit. Regulatory authority audits 
may take place at any time during or after the study without advance notice. If such an audit occurs, 
the Investigator must agree to allow access to required subject records. By signing this protocol, 
the Investigator grants permission to personnel from the sponsor, its representatives and appropriate 
regulatory authorities for on-site monitoring of all appropriate study documentation, as well as on-
site review of study procedures. 
12.3.13 Confidentiality, Use of Information and Publication 
All information supplied by the sponsor in connection with this study and not previously published, 
is considered confidential information. This information includes, but is not limited to, data, 
materials (i.e., the clinical protocol, eCRFs), equipment, experience (whether of a scientific, 
technical, engineering, operational, or commercial nature), designs, specifications, know-how, 
product uses, processes, formulae, costs, financial data, marketing plans and direct selling systems, 
customer lists and technical and commercial information relating to customers or business 
projections used by the sponsor in its business. Any data, inventions or discoveries collected or 
developed, as a result of this study is considered confidential. This confidential information shall 
remain the sole property of the sponsor, shall not be disclosed to any unauthorized person or use in 
any unauthorized manner without written consent of the sponsor, and shall not be used except in 
the performance of the study. 
The information developed during the course of this clinical study is also considered confidential, 
and will be used by the sponsor in connection with the development of the drug. The information 
may be disclosed as deemed necessary by the sponsor. To allow the use of the information derived 
from this clinical study, the Investigator is obliged to provide the sponsor with complete test results 
and all data developed in the study. The information obtained during this study may be made 
available to other Investigators who are conducting similar studies. 
The Investigator shall not make any publication related to this study without the express written 
permission of the sponsor. Should the Investigator wish to publish or present the results of this 
study, the Investigator agrees to provide the sponsor with an abstract, manuscript, and/or 
presentation for review ninety (90) days before submission for publication/presentation. The 
sponsor retains the right to delete from the manuscript confidential information and to object to 
suggested publication and/or its timing (at the sponsor’s sole discretion.) 
12.3.14 End of the Trial 
Upon a subject's completion in the study, the IP will no longer be available to the subject and all 
used and unused IP must be collected. The Investigator can, at their discretion, discuss alternative 
treatments with the subject.

The end of the trial is defined as the time at which the last subject has completed their last visit in 
the study. All eCRFs will be completed in compliance with the protocol and all relevant data and/or 
records will be forwarded to the CRO, as applicable. The Investigator must submit a final report to 
the IRB. The monitor will conduct a close out visit at the site. 
12.3.15 Clinical Study Report 
At the end of the study a full report per requirements of sponsor and regulatory authorities will be 
prepared which will include a narrative of the clinical conduct and results of the study, a statistical 
report including a description of the analysis performed, and other documentation as may be 
appropriate. The report will be in electronic format according to eCTD and ICH formatting 
standards and guidelines.21 ANDA summary tables will also be generated. Data sets will be 
provided in SAS® transport (.xpt) format with appropriate description (Read Me) files as required 
by FDA. 
12.3.16 Termination of the Study 
The sponsor reserves the right to terminate the study at any time for administrative or safety 
reasons. If the sponsor prematurely terminates or suspends the study, or one or more investigative 
sites participating in the study, the Investigator and/or CRO (as contracted) must promptly inform 
the IRB. As applicable, the Investigator may be required to follow up on the subject and/or refer 
them for appropriate care.
