Efficacy Endpoint 
The primary efficacy endpoint is the propotiion of patients in each treatment 
group who are considered a Clinical Success at Day 29 ± 2, as defined by an 
IGA score of 0 (clear) or I (almost clear) with at least a 2 grades reduction 
from baseline at Day 29 ± 2. That is, at Day 29 ± 2, patients with an JGA 
score of 3 or 4 at baseline must achieve a score of 0 or 1 and patients with an 
IGA score of 2 at baseline must achieve a score of 0 to be considered a 
Clinical Success. 
Therapeutic 
Efficacy Analysis 
Superiority of the Test shampoo over the Vehicle shampoo at Day 29 ± 2 will 
be tested using a two-sided Cochran-Mantel-Haenszel (CMH) test, stratified 
by clinical site, at the 5% significance level. The primary analysis will be 
performed using an imputation method of analysis for missing data in the 
Intent-to-Treat (ITT) population. Patients discontinued because of lack of 
treatment effect will be included in the primary analysis as treatment failures. 
The following two sensitivity analyses will also be performed on the primary 
efficacy endpoint: 
1. 
Primary analysis will be performed also including patients without an 
assessment at Day 29 ± 2. Patients with missing data at Day 29 ± 2 will 
be considered clinical failures. 
2. 
Primary analysis will be performed also including patients without an 
assessment at Day 29 ± 2. Patients from the Vehicle group with missing

Determination 
data at Day 29 ± 2 will be treated as clinical successes and patients from 
the Test group with missing data at Day 29 ± 2 will be treated as clinical 
failures. 
Adverse events will be classified using standard MedORA terminology 
Version 18.1 or higher and summarized by treatment group. Summary tables 
comparing the type, date of onset, date of resolution, incidence, severity, 
Investigator's opinion of relationship to the study drug, action taken, and 
outcome will be prepared by treatment group. If sufficient data exist, adverse 
event frequencies will be compared between treatments using Fisher's exact 
test or a similar test. 
Concomitant medication use during the study will be tabulated by patient. 
Signs and symptoms of scalp psoriasis will not be considered adverse events, 
unless in the Investigator's opinion, they have increased in frequency and/or 
severity to such an extent that the Investigator/patient considers that it is in 
the patient's best interest to be dropped from continued participation in the 
study and given alternative therapy for their condition. 
Ocular discomfort, vital signs and skin assessments will be analyzed for both 
treatments. Ocular safety evaluations will be assessed at the discretion of the 
Investigator based on the findings of the HEENT examination performed at 
each visit along with the ocular discomfort symptoms repmted by the patient. 
Ocular discomfort will be assessed by subjects and reported to staff during 
clinic visits (Appendix D). 
The primary statistical analysis of interest is a comparison of clinical success, 
as defined by an IGA score of 0 (clear) or 1 (almost clear) with at least 2 
grades reduction from baseline at Day 29 ± 2, of the Test treatment, 
desoximetasone 0.25% shampoo, to the clinical success of the respective 
Vehicle shampoo in the ITT population. Based on results fl-om Taro's Phase 
II study 71342608 the clinical success of the Test formulation is expected to 
be approximately 27% for an application duration of 15 minutes. The clinical 
success of the Vehicle formulation is expected to be approximately 10% for 
the same application duration. Based on a two-sided, Yates' continuity-
corrected Z-test and a pooled response rate for the standard error of the 
difference in propmtions, 166 patients in the active group and 166 patients in 
the placebo group of the ITT population will provide at least 97% power to 
demonstrate superiority at the 5% significance level (p < 0.05) for the active 
treatment over placebo. To allow for about 10% of patients who may drop out 
from the study or arc otherwise non-evaluable, up to 370 patients may be 
enrolled ( 185 in the active group and 185 in the placebo group).

Evaluate the Efficacy and Safety of Desoximetasone 0.25% Shampoo in Patients with Mild to Severe Scalp 
Psoriasis 
7.0 
INTRODUCTION 
Taro Pharmaceuticals U.S.A., Inc. (Taro) plans to submit an Investigational New Drug 
Application (IND) for a new formulation of desoximetasone; desoximetasone 0.25% shampoo. 
This product contains a potent corticosteroid to be indicated for the treatment of plaque psoriasis 
in patients 12 years of age or older. 
7.1 
Disease Being Treated 
Psoriasis is an immune (T-cell)-mediated inflammatory skin disease that affects 
approximately 2% of the western population. The most common type of psoriasis in both 
adults and children 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 repmis 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, 
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 
At least 50% of all psoriasis cases have scalp psoriasis. Although head represents only 
10% of the whole body surface, the visibility and symptoms of scalp psoriasis can be 
seriously debilitating for many patients, inducing social and emotional distress and 
negatively impacting quality of life.4 Scalp psoriasis is more difficult to treat compared to 
psoriasis of the body, because the skin of the scalp is less accessible to topical treatments 
primarily because of the presence of hair. Moreover, vehicles used in psoriasis 
medications are often not cosmetically acceptable for scalp treatment, thereby negatively 
impacting treatment adherence. There is a need for effective, safe and cosmetically 
acceptable products for the treatment of scalp psoriasis to improve both compliance and 
response to treatment. 5 
Psoriasis severity is determined using various tools, the most extensively studied index 
being the Psoriasis Area and Severity Index (PASl), which is a measure of the average 
redness, thickness, and scaliness of the lesions (each graded on a 0-4 scale), weighted by 
the % body surface area of involvement. Scalp psoriasis is often assessed using the 
Psoriasis Scalp Severity Index (PSSI) or the Physician's Global Assessment (PGA). 
However, the validity and sensitivity of such tools are not well characterized and still 
under investigation. Indicators for the effect of psoriasis on quality oflife and response to 
treatment often influence the overall severity of the disease. lienee, a clinically 
meaningful global assessment by the physician characterizing lesions on a 5-point scale is 
considered most appropriate and recommended by the FDA for the purpose of psoriasis 
clinical trials.

7.2 
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 patient. Scalp psoriasis treatments

Evaluate the Efficacy and Safety ofDesoximetasone 0.25% Shampoo in Patients with Mild to Severe Scalp 
Psoriasis 
historically include topical creams, sprays, lotions, foams, and the more recently 
introduced shampoos. Examples of marketed products include corticosteroids (Topicmi@, 
Clobex"'), Vitamin A and D derivatives (Tzorac@, Dovonex@), NSAlDs (salicylic acid), 
etc. For more severe cases, systemic therapy (methotrexate, oral retinoids, UV light, 
biologics, etc) may be warranted; however, the side effect profile ofthese products limits 
their use. 1'2'5'8' 9 
Desoximetasone is a high potency synthetic COiiicosteroid marketed in a number of 
formulations: gel (0.05%), cream (0.05% and 0.25%), and ointment (0.05% and 0.25%). 
All these formulations are encompassed under the Topicmi@ brand, acquired by Taro 
Pharmaceuticals U.S.A., Inc. (Taro) in 2004. Most recently, Taro received approval on 
April 11, 2013 for a new dosage form (spray) under NDA #204141, Topicort@ 
(desoximetasone) Spray, 0.25%, a super high potency formulation that is indicated for the 
treatment of plaque psoriasis in patients 18 years of age or older. 10 Topical application of 
high potency steroids at the recommended dosing levels are usually well tolerated in all 
populations, with less than 2% of patients reporting adverse reactions (7% in the pediatric 
population). The most commonly reported adverse events are burning, stinging, pruritus, 
and skin thinning/atrophy .1'2'5'8'9 
Shampoos are considered a preferred treatment option for scalp psoriasis because of ease 
of application and cosmetic acceptability. There are many OTC coal tar shampoos in the 
market for treating mild scalp psoriasis. For the moderate-severe cases, a prescription 
shampoo containing potent corticosteroids is available in the market (Ciobex"' shampoo, 
clobetasol propionate, 0.05% ). 
A new formulation of desoximetasone - Desoximetasone Shampoo, 0.25% has been 
developed by Taro Pharmaceuticals U.S.A., Inc. (Taro), and is the Test product used in 
this study. 
7.3 
Scientific and Statistical Considerations 
This phase III study (DSXS 1536) has been designed based on review of multiple clinical 
studies in psoriasis, including Taro's phase II dose-ranging study on Desoximetasone 
Shampoo, 0.25% (DSXS 1411)
12 and those studies submitted as part of the NDA for 
currently marketed Taclonex@ (betamethasone and calcipotriene) scalp suspension (NDA 
Number: 22-185) 
13 and Clobex'" ( clobetasol propionate) shampoo, 0.05% (Gal derma 
Laboratories, NDA Number: 21-644). 
The FDA statistical review and analyses conducted for phase Ill studies for Taclonex'l<' 
(betamethasone and calcipotriene) scalp suspension, 
13 were used to select the patient 
population (patients with a clinical diagnosis of mild to severe plaque psoriasis of the 
scalp) and the definition of Clinical Success (Investigator's Global Assessment (IGA) of 
disease severity score ofO (clear) or I (almost clear) with at least a 2-grade improvement 
from baseline IGA at the end of the treatment) for this phase III study (DSXS 1536). The 
phase III studies for Clobex'" (clobetasol propionate) shampoo, 0.05% indicated a success

Evaluate the Efficacy and Safety of Desoximetasone 0.25% Shampoo in Patients with Mild to Severe Scalp 
Psoriasis 
rate of 44% in the active group and approximately 2% in the vehicle group after 4 weeks 
of treatment. 14 
Based on these NDA studies, previous communications with Sponsor, and pre-IND 
discussions regarding this study with the FDA (PIND# 118881 briefing package and 
FDA letter dated 9118/2013), a 28-day treatment period was considered appropriate to 
determine therapeutic efficacy of the Test shampoo formulation. 
Taro's phase II dose-ranging study on Desoximetasone Shampoo, 0.25% (DSXS 1411) 
was designed to evaluate therapeutic efficacy using multiple application durations of the 
product. The results of this phase II study were used to determine the appropriate 
duration of application (15 minutes) and the expected clinical success rate for subsequent 
phase III efficacy studies. Based on data from this study, a population of 370 patients, 
with up to 185 patients receiving Test treatment and up to 185 patients receiving Vehicle 
treatment, for an application time of 15 minutes was considered sufficient to demonstrate 
efficacy, safety and superiority to Placebo for the phase 1II study (DSXS 1536). 
The application time of 15 minutes was also supported based on results from Taro's in-
vitro study that used tape stripping and vertical Franz cells to investigate the deposition of 
desoximetasone from a shampoo formulation. 15 At 10 minutes following application, 2: 
99% of the applied dose was recovered on the skin surface and no quantifiable amounts 
of desoximetasone were detected in the receptor compartment or inside the skin. 
Therefore, application durations of< 15 minutes will not be used in the Phase 3 studies. 
Application durations of> 15 minutes are expected to reduce the patient's dosing 
compliance and are thus considered impractical for patient's daily routine. 
Desoximetasone is currently marketed by Taro as a gel (0.05%), cream (0.05% and 
0.25%) and ointment (0.05% and 0.25%) indicated for the relief of the inflammatory and 
pruritic manifestations of corticosteroid-responsive dermatoses, and as a spray (0.25%) 
indicated for the treatment of plaque psoriasis in patients 18 years of age or older. The 
new dosage form shampoo, the Test product for this study, was formulated with a highest 
marketed concentration (0.25%) to facilitate convenience by reducing contact time with 
the skin and to improve treatment compliance and efficacy. 
7.4 
.Justification for use of Vehicle Shampoo 
A Vehicle group will be included to confirm the sensitivity of the clinical endpoint and to 
demonstrate that the Test product is therapeutically superior to a Vehicle formulation that 
contains no active ingredient to treat scalp psoriasis. A sample size of 185 patients is the 
minimum number of patients that can be enrolled into the Vehicle group to ensure high 
statistical power (97% or more) to show a difference at p < 0.05 (two-sided) between the 
active treatment and Vehicle (according to a 1:1, Test: Vehicle randomization scheme). 
7.5 
Risks and Benefits 
The risks and benefits to patients enrolled in clinical research studies that include a 
vehicle treatment group must be carefully considered based on three main criteria,

namely: the disease being treated, the availability, efficacy and safety of already 
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 
USA Federal Government's Depmtment of Health and Human Services, has issued a 
detailed guidebook to Institutional Review Boards (IRBs) that includes discussion on the 
use of placebo in clinical studies.
17 
Patients eligible for randomized treatment will have a 50% chance of receiving the 
Vehicle product. Although the potential for any drug-related side effects of significance 
occurring during the study are low, the risk is higher in the active treatment group than in 
the Vehicle group. 
All patients enrolled in this study will receive the benefit of fi·ee specialized medical care 
beyond standard medical treatment that would be expected through most health insurance 
plans. In addition, the patient will receive a stipend for participation to cover costs and 
expenses associated with trips to the medical facility.

A Randomized, Double-Blind, Vehicle-Controlled, Parallel-Design, Multiple-Site, Phase Ill Clinical Study to 
Evaluate the Efficacy and Safety of Desoximetasone 0.25% Shampoo in Patients with Mild to Severe Scalp 
Psoriasis 
Patients in each randomized treatment group will apply product once daily, according to 
provided instructions, for a total of28 days starting on Day I. 
During the study patients will visit the clinical center for a total of 3 scheduled visits: 
• 
Visit 1 (Day -1 to 1): Randomization 
• 
Visit 2 (Day 14 ± 2): Interim Visit 
• 
Visit 3 (Day 29 ± 2): End of Study or Early Termination 
The primary efficacy endpoint is the proportion of patients in each treatment group who 
are considered a Clinical Success, as defined by an IGA score of 0 (clear) or 1 (almost 
clear) with at least a 2-grade improvement from baseline IGA at Day 29 ± 2. That is, at 
Day 29 ± 2, patients with an IGA score of 3 or 4 at baseline must achieve a score of 0 or 
I, patients with an IGA score of 2 at baseline must achieve a score of 0 to be considered a 
Clinical Success. The 5-point IGA score represents an overall severity of scalp psoriasis 
based on plaque elevation, scaling and erythema. Severity represented by a score of 0-4 is 
categorized as 'clear', 'minimal', 'mild', 'moderate' or 'severe'. Refer to Appendix A for 
IGA scoring. 
The safety profile of each treatment group will be evaluated by comparing adverse 
events, dermal and ocular discomfmt and vital signs obtained through the study duration. 
Ethical consideration related to this protocol and the use of human patients will be 
reviewed by an IRB.

and results of Taro's in-vitro study that used tape stripping and vertical Franz cells to 
investigate the deposition of desoximetasone from a shampoo formulation.
15 Based on 
these studies, previous communications with Sponsor, and pre-IND discussions with the 
FDA (PIND# 118881 ), a daily application of shampoo for 15 minutes for a 28-day 
treatment duration and a population of 370 patients (185 patients receiving active 
treatment and 185 patients receiving vehicle treatment) was considered appropriate to 
demonstrate therapeutic efficacy and safety of desoximetasone 0.25% shampoo (Taro) 
compared to a Vehicle shampoo.

bottle. The shampoo is to be gently rubbed into the affected area. The same 
procedure is to be followed for other affected areas on the scalp. Patients will be 
instructed to use only enough to cover affected areas and avoid application to 
face, groin, armpits, lips or eyes. If during application the product comes in 
contact with the eyes or eyelids, patients will be instructed to rinse the area with 
abundant water immediately. Patients should not cover the head with a shower 
cap while the shampoo is on the scalp. The shampoo is to be left in place for 15 
minutes before adding water, lathering and rinsing hair and scalp completely. 
Patients will be instructed to begin dosing on the evening of enrollment or in the 
morning on the day following enrollment. Treatments are to be applied once 
daily at approximately the same time, on each day, for 28 days starting on Day 1. 
Patients should not apply more than 50 ml of study product per week. 
9.4.2 
Identity of Investigational Product 
The following products will be used in the study: 
• 
Test: 
Desoximetasone 
0.25% 
shampoo, 
manufactured 
by 
Taro 
Pharmaceuticals. 
• 
Placebo: Test Vehicle shampoo, manufactured by Taro Pharmaceuticals. 
Study products will be supplied in 120 ml bottles. 
All randomized study products will be blinded and packaged in blinded sealed 
boxes. Each bottle will be identified by a label bearing the Sponsor name, 
protocol number, randomization number, treatment duration, a statement that the 
study product is for Investigational Use Only, a place for patient initials and the 
date the bottle was dispensed. The study staff will dispense the study product 
bottle only to those patients identified by the Investigator. The study staff will 
instruct the patients on the use and return of study product. 
Individual bottles of study product will be packaged in blocks. The 
randomization will be generated in blocks of 4. Four (4) patients' worth of 
product (2 patients worth of Test product, 2 patients worth of Vehicle product), 
based on a I: 1 randomization ratio, will be packed into a larger box. This larger 
box will be designated "one block" of study product. Further details for 
randomization are provided in section 9.4.3. 
The study product will be shipped to each Investigator's site from a centralized 
pharmacy. The Principal Investigator at each site is responsible for ensuring that 
all study products are stored in a locked, secure location, with access limited to 
the Investigator and his/her designee(s). An accurate inventory of the study 
product will be maintained in accordance with federal regulations. Study product 
will be stored at controlled room temperature 15-30°C (59-86°F).

Once the site has been notified that they may do so, all unused study product and 
empty or partially used bottles of study product may be returned to the Sponsor 
or designee. 
9.4.3 
Method of Assigning Patients to Treatment Groups 
At Visit 1 eligible patients will be randomized to the study and assigned a 
randomization number. Patient numbers will consist of a 2-digit site number and 
4-digit randomization number. The 4-digit randomization numbers will be 
assigned in ascending order beginning with the lowest number at each study site. 
The study product will be packaged and blinded by an independent clinical 
packaging company. The randomization will be generated in blocks of 4 to 
accommodate the 1:1 randomization scheme (2 Test:2 Vehicle). 
Each eligible patient will receive 2 x 120 ml bottles of study product (Test or 
Vehicle). Patients will be randomized to a treatment group in a blinded fashion 
by assigning randomization numbers in ascending sequential order starting with 
the lowest available randomization number at each site. All patients randomized 
will be identified by initials, date of birth, and a unique six-digit patient number. 
A perforated two-pmi label will be attached to each of the small sized boxes of 
study product supplies. Both pieces of the label will include the following 
information: Protocol number, randomization number, dosing instructions, space 
for patient's initials, statement that the study product is for investigational use 
only, space for dispensing date and the Sponsor's name. One part of the label 
shall remain attached to the box. The other part will be removed prior to 
dispensing and attached to the patient source documents. In addition all patients 
will be provided with written instructions on how to use the study product. Prior 
to dispensing, study product will be weighed. 
9.4.4 
Study Blind 
The Investigator, staff at the study site and study monitors will be blinded to the 
patient assignment. Each study site will have at least one Independent Dispenser. 
The role of the Independent Dispenser is to dispense and collect all study product 
bottles from the patients and to ensure the study product logs are repmied 
correctly. They should not be involved in collecting any efficacy or safety data in 
the study, thus ensuring the integrity of the study blind. 
To ensure that information that could potentially bias handling of data is not 
disclosed, the clinical packaging company will hold the randomization scheme 
until release is requested by the Sponsor or designee. Unblinding code in the 
form of a scratch off portion of the product label attached to the source 
documents will be retained at the study site to be opened in case of medical 
emergency only.

Whenever possible, the Novum Medical Monitor must be contacted before 
breaking the blind for any patient. In the event the blind is broken for any reason 
Sponsor and Novum will be notified as soon as possible in writing of the details 
ofthe occurrence. 
The bottles used for both study products will be similar in size, shape and color. 
This will allow the treatment phase of the study to be conducted under double-
blind conditions, such that neither the patient nor the Investigator or study staff 
members will know the identity of each patient's treatment. 
9.4.5 
Compliance 
Patients will be considered compliant with dosing if they administered 75%-
125% of the required 28 doses and did not miss 4 or more consecutive doses and 
did not dose more than twice on any particular day. Compliance with dosing will 
be verified by the use of patient diaries.

Adverse Events 
The patients will be monitored throughout the study for any Adverse Events. AEs will be 
collected through both solicited and unsolicited means and subsequently coded in tabular 
form using the MedORA (Version 18.1 or higher) Adverse Event Dictionary. The patients 
will be encouraged to report signs, symptoms, and any changes in health to the clinic staff. 
Severity of each AE will be determined by the staff based on observation and questioning 
of the patients. The Investigator will judge the relationship of the event to the study 
treatments. Adverse events should be followed up until they have resolved or stabilized. In 
the opinion of the Investigator, if the patient suffers an AE that warrants discontinuation of 
the study drug due to interference with age-appropriate instrumental ADL (Activities of 
Daily Living), for example preparing for meal, shopping for groceries or clothing, using the 
telephone, etc. the patient will be followed until the AE resolves or is considered stable. 
Any subject that discontinues the study because of an adverse event will be followed until 
resolution or stabilization of the adverse event. 
9.7.1 
Adverse Event Definitions 
Adverse Event: Any untoward medical occurrence in a patient or clinical 
investigation patient administered a pharmaceutical product and which does not 
necessarily have a causal relationship with treatment. An AE can therefore be 
any unfavorable and unintended sign, symptom, or disease, temporally associated 
with the use of a medicinal (investigational) product, whether or not related to 
this product. This includes events not seen at baseline, or worsened even if 
present at baseline. 
Unexpected Adverse Event: An adverse event where the nature or severity of is 
not consistent with the applicable product information (e.g., Investigator's 
Brochure for an unapproved investigational product or package inse1i/summary 
of product characteristics for an approved product). 
Adverse Drug Reaction: All noxious and unintended responses to a medical 
product related to any dose should be considered adverse drug reactions. The 
response to a 'medical product' means that a causal relationship between a 
medicinal product and an adverse event is at least a reasonable possibility, i.e., 
the relationship cannot be ruled out. 
9.7.2 
Severity of Adverse Event 
The severity of the adverse event will be graded by the Investigator using the 
following criteria as guidelines: 
• 
MILD: Awareness of symptom but does not interfere with routine 
activities. 
• 
MODERATE: Discomfort sufficient to interfere with routine activities. 
• 
SEVERE: Impossible to perform routine activities.

9.7.3 
Relationship of Adverse Event 
Relationship to the Study Product 
• 
NOT RELATED: Any AE that is clearly not related to use of the study 
drug. 
• 
POSSIBLE: The association of the AE with the study drug is unknown; 
however, a relationship between the drug and event cannot be ruled out. 
• 
PROBABLE: There is reasonable temporal relationship between the use 
of the study drug and the AE. Based upon the Investigator's clinical 
experience, the association of the event with the study drug seems likely. 
• 
DEFINITE: The AE occurs following the application of the study drug 
and it cannot be reasonably explained by any other known characteristics 
of the patient's clinical state, environmental or toxic factors, or other 
modes of treatment administered to the patient. It disappears or decreases 
upon discontinuation of the study product and reappears on a re-
challenge of the study drug. 
9.7.4 
Patient's Participation Stopping Criteria 
In the opinion of the Investigator, if the patient suffers an AE that warrants 
discontinuation of the study drug because of interference with age-appropriate 
instrumental ADL (Activities of Daily Living), for example preparing for meal, 
shopping for groceries or clothing, using the telephone, etc. the patient will be 
followed until the AE resolves or is considered stable. Any subject that 
discontinues the study because of an adverse event will be followed until 
resolution or stabilization of the adverse event.

Serious Adverse Events 
9.8.1 
Definition of a Serious Adverse Event 
A Serious Adverse Event (SAE) is any untoward medical occurrence that at any 
dose suggests a medically significant hazard, including any event that: 
• 
Results in death -
includes all deaths, even those that appear to be 
completely unrelated to study treatment (e.g., car accident where patient 
is a passenger). 
• 
Is life-threatening -
in the view of the Investigator, the patient is at 
immediate risk of death at the time of the event. 
• 
Results in persistent or significant disability or incapacity (substantial 
disruption of one· s ability to conduct normal life). 
• 
Requires 
inpatient 
hospitalization 
or 
prolongation 
of existing 
hospitalization.

Causes congenital anomaly or birth defect. 
• 
Is an important medical event that may not be immediately life-
threatening or result in death or hospitalization, but may jeopardize the 
patient or may require medical or surgical intervention to prevent one of 
the serious outcomes listed above (e.g., intensive treatment in an 
emergency room, convulsions that do not result in hospitalizations).

STATISTICAL METHODS 
10.1 
Statistical Plan 
A Statistical Analysis Plan (SAP), 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 Statistical Analysis Plan. 
All statistical analysis will be conducted using SAS®, Version 9.4 or higher. 
10.2 
Determination of Sample Size 
The primary statistical analysis of interest is a comparison of clinical success, as defined 
by an IGA score of 0 (clear) or 1 (almost clear) with at least 2 grades reduction from 
baseline at Day 29 ± 2, of the Test treatment, desoximetasone 0.25% shampoo, to the 
clinical success of the respective Vehicle shampoo in the ITT population. Based on 
results from Taro's Phase II study 71515008, the clinical success ofthe Test formulation 
is expected to be approximately 27% for an application duration of 15 minutes. The 
clinical success of the Vehicle formulation is expected to be approximately 10% for the 
same application duration. Based on a two-sided, Yates' continuity-corrected Z-test and a 
pooled response rate for the standard error of the difference in propmiions, 166 patients 
in the active group and 166 patients in the placebo group of the ITT population will 
provide at least 97% power to demonstrate superiority at the 5% significance level (p < 
0.05) for the active treatment over placebo. To allow for about 10% of patients who may 
drop out from the study or are otherwise non-evaluable, up to 370 patients may be 
enrolled (I 85 in the active group and 185 in the placebo group).

CONFIDENTIAL PROTOCOL 
A Randomized, Double-Blind, Vehicle-Controlled, Parallel-Design, Multiple-Site, Phase Ill Clinical Study to 
Evaluate the Efficacy and Safety of Desoximetasone 0.25% Shampoo in Patients with Mild to Severe Scalp 
Psoriasis 
10.4 
Baseline Comparability 
Baseline comparability of each treatment group will be evaluated separately in the ITT 
and Safety populations. Comparative analyses will use appropriate statistical tests (e.g., 
one-way analysis of variance, Cochran-Mantei-Haenszel test). 
The following baseline demographics (determined from their initial study visit) will be 
evaluated: 
• 
Age (years) 
• 
Gender (male/female) 
• 
Ethnicity (Hispanic/non Hispanic) 
• 
Race (White, Black/African American, Native Hawaiian or Other Pacific 
Islander, Asian, American Indian or Alaska Native, Other) 
• 
%Scalp affected 
• 
Number of months and/or years patient has suffered from symptoms caused by 
scalp psoriasis 
Descriptive statistics by treatment group will be presented. 
10.5 
Efficacy Endpoint 
The primary efficacy endpoint is the propotiion of patients in each treatment group who 
are considered a Clinical Success at Day 29 ± 2, as defined by an IGA score of 0 (clear) 
or 1 (almost clear) with at least a 2 grades reduction from baseline at Day 29 ± 2. That is, 
at Day 29 ± 2, patients with an IGA score of 3 or 4 at baseline must achieve a score of 0 
or 1 and patients with an IGA score of 2 at baseline must achieve a score of 0 to be 
considered a Clinical Success. 
10.6 
Efficacy Analysis 
10.6.1 Primary Analysis 
Superiority of the Test shampoo over the Vehicle shampoo at Day 29 ± 2 will be 
tested using a two-sided Cochran-Mantei-Haenszel (CMH) test, stratified by 
clinical site, at the 5% significance level. The primary analysis will be performed 
using an imputation method of analysis for missing data in the Intent-to-Treat 
(ITT) population. Details of the imputation method will be delineated in the SAP. 
Patients discontinued because of lack of treatment effect will be included in the 
primary analysis as treatment failures. 
10.6.2 Sensitivity Analyses 
The following two sensitivity analyses will also be performed on the primary 
efficacy endpoint:

1. 
Primary analysis will be performed also including patients without an 
assessment at Day 29 ± 2. Patients with missing data at Day 29 ± 2 will be 
considered clinical failures. 
2. 
Primary analysis will be performed also including patients without an 
assessment at Day 29 ± 2. Patients fi·om the Vehicle group with missing data 
at Day 29 ± 2 will be treated as clinical successes and patients from the Test 
group with missing data at Day 29 ± 2 will be treated as clinical failures. 
10.7 
Safety Analysis 
Adverse events will be classified using standard MedORA terminology Version 18.1 or 
higher and summarized by treatment group. Summary tables comparing the type, date of 
onset, date of resolution, incidence, severity, Investigator's opinion of relationship to the 
study drug, action taken, and outcome will be prepared by treatment group. If sufficient 
data exist, adverse event frequencies will be compared between treatments using Fisher's 
exact test or a similar test. 
Concomitant medication use during the study will be tabulated by patient. 
Signs and symptoms of scalp psoriasis wiii not be considered adverse events, unless in 
the Investigator's opinion, they have increased in fi·equency and/or severity to such an 
extent that the Investigator/patient considers that it is in the patient's best interest to be 
dropped from continued participation in the study and given alternative therapy for their 
condition. 
Ocular discomfort, vital signs and skin assessments wiii be analyzed for both treatments. 
Ocular safety evaluations will be assessed at the discretion of the Investigator based on 
the findings of the HEENT examination performed at each visit along with the ocular 
discomfot1 symptoms reported by the patient. Ocular discomfort will be assessed by 
subjects and reported to staff during clinic visits (Appendix D).
