Study Products 
• 
Test: Permethrin Cream, 5% (Encube Ethicals) 
• 
 Reference: Elimite™ Cream (permethrin) 5% (Prestium Pharma, Inc.) 
Study products will be supplied in tubes (60 grams).  
Dosage Regimen 
Patients will administer a single dose of study product on the day of Visit 1 
(i.e., Day 1). A second application may be required if evidence of scabies 
infestation is microscopically demonstrated (i.e., living mites, viable mite 
eggs, or mite fecal matter) are present on Visit 2 (Day 14 ± 4). Each patient 
will receive up to two applications. 
Route of 
Administration 
Topical 
Treatment 
Randomization 
1:1 (Test: Reference) 
Patient Population 
Approximately 250 patients, 2 years of age and older with clinically 
documented evidence of active infestation with Sarcoptes scabiei (scabies). 
Study Design 
Randomized, double-blind, parallel-group, multiple-site bioequivalence  
study with clinical endpoints 
Study Conduct 
Eligible patients will be randomized in a 1:1 ratio to one of the two 
treatments (Test or Reference) at Visit 1. Patients will administer a single 
application of study product on the day of Visit 1 (i.e., Day 1). A second 
application may be required if presence of active scabies infestation is 
microscopically demonstrated (i.e., living mites, viable mite eggs, or mite

• 
Visit 2 (Day 14 ± 4): Interim Visit 
• 
Visit 3 (Day 28 ± 4): End of Study Or Early Termination 
Final assessments will be carried out at Visit 3 (Day 28 ± 4), which is the 
test-of-cure visit. Therapeutic cure of scabies will be evaluated based on 
microscopic evidence of absence of scabies infestation (i.e., no living mites, 
no viable mite eggs, and no mite fecal matter), visual evidence of absence of 
new lesions and healing of original lesions, regardless of the presence of 
post-scabetic nodules (i.e., post-scabetic nodules need not be considered as 
new lesions or persistence of old lesions). 
Inclusion Criteria 
1. Male or non-pregnant, non-lactating female, 2 years of age or older. 
2. If female and of childbearing potential, prepared to abstain from sexual 
intercourse or use a reliable method of contraception during the study 
(e.g., double barrier methods, IUD, oral, transdermal or injected 
hormonal contraceptives). Female patients using hormonal contraceptives 
should have been on the same product/dosing regimen for at least 28 days 
before baseline and should not change this regimen during the study.  
3. Signed informed consent that meets all criteria of current FDA and ICH 
regulations. For patients who are considered minors in the state the study 
is being conducted (< 18 years in most states) the parent or legal guardian 
should sign the consent form and the child will be required to sign a 
patient “assent” form, as appropriate. Patients 11-17 years of age will 
read and sign an IRB-approved assent form and patients 6-10 years of 
age will provide verbal assent. Patients 2-5 years of age will be exempt 
from providing assent based on the child’s comprehension and cognitive 
skills. 
4. Clinical diagnosis of active scabies by presence of a burrow and/or 
typical scabietic lesions at the classic sites of infestation. 
5. Parasitological confirmation of clinical diagnosis with demonstration 
under light microscope of mites and/or their products (larvae, eggs or 
fecal material). 
6. Symptom score of 2 or 3 on a 4-point rating scale of 0-3 for nocturnal 
itching/pruritus. 
7. Ability to apply or have study product applied as directed. If patient is a 
child, then parent/guardian will apply study product to him/her. 
Exclusion Criteria 
1. Patients who are pregnant, lactating, or planning to become pregnant 
during the study. 
2. Any systemic or dermatologic disorder that, in the opinion of the 
Investigator, will interfere with the study results or increase the risk of 
adverse events (AEs). 
3. Known hypersensitivity to permethrin cream or any of its components,

16. Previous participation in this study. 
Efficacy Endpoint 
The primary efficacy endpoint is the proportion of patients in each treatment group 
with Therapeutic Cure (parasitological cure plus clinical cure) of scabies at the test-
of-cure visit conducted at Day 28 ± 4. A parasitological cure is defined as failure to 
demonstrate microscopically the presence of scabies infestation (i.e., no living mites, 
no viable mite eggs, and no mite fecal matter present). A clinical cure is defined as 
visual evidence of absence of new lesions and healing of original lesions, regardless 
the presence of post-scabietic nodules (i.e., post-scabietic nodules need not be 
considered as new lesions or persistence of old lesions). 
Evaluation of 
Therapeutic 
Equivalence  
Primary Analysis: 
Therapeutic equivalence of the Test product to the Reference product based 
on the primary endpoint will be evaluated in the per-protocol (PP) population. 
If the 90% confidence interval on the absolute difference between the 
proportion of patients who are considered a Therapeutic Cure (primary) in the 
Test and Reference groups is contained within the range [-20%, +20%] then

Confidential Protocol 71675502  Rev 1  November 3rd, 2017  Encube Ethicals   Page 11 of 42 
 
 
therapeutic equivalence of the Test product to the Reference product will be 
considered to have been demonstrated. 
Supportive Analyses: 
The following supportive analyses will be performed for the primary 
endpoint: 
1. The primary analysis will be performed including patients who 
completed Visit 2 within 14 ± 2 days and Visit 3 within 28 ± 4 days. 
2. The primary analysis will be performed including patients who 
completed Visit 2 within 14 ± 2 days and Visit 3 between Day 26 and 
Day 32, inclusive. 
3. The primary analysis will be performed including patients who 
completed Visit 2 within 14 ± 2 days and Visit 3 within 28 ± 2 days. 
To declare therapeutic equivalence of the Test product to the Reference product, 
therapeutic equivalence must be demonstrated for only the primary analysis. 
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 for the primary efficacy endpoint in the PP population (for 
equivalence testing). The treatment-by-site interaction will be evaluated by 
the Breslow-Day test for homogeneity of the odds ratio at the 5% significance 
level (p < 0.05). A site(s) with a low enrollment rate(s) may be pooled with 
its geographically closest site, so as to avoid bias in the estimation of a 
treatment-by-site interaction effect. The pooling will be done for low 
enrolling sites that account for less than 4-7% of the total number of patients 
in the PP population at the site with the highest enrolling rate in the PP 
population. If the treatment-by-site interaction term is found to be statistically 
significant (p < 0.05) for the primary endpoint, then the interaction term will 
also be assessed for clinical relevance before pooling the data across sites. 
This will include examination of Therapeutic Cure rates at each site where 
sample sizes per treatment may be influential in the assessment of the 
interaction. 
Safety Analysis 
Adverse events will be classified using standard Medical Dictionary for 
Regulatory Activities (MedDRA) terminology Version 20.0 or higher and 
summarized by treatment group. Summary tables comparing the type, 
incidence, date of onset, date of resolution, severity, action taken, outcome 
and Investigator’s opinion of relationship to the study product will be 
prepared by treatment group. If sufficient data exist, AE frequencies will be 
compared between treatments using Fisher’s exact test or a similar test. 
Signs and symptoms of scabies 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/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. 
Concomitant medication use during the study will be tabulated by patient and 
by treatment. 
All patients who are randomized to the active treatment period of the study 
who received study product will be included in the comparative safety 
analysis. 
Sample Size 
Determination 
For the primary endpoint analysis (proportion of patients in the PP population 
who are considered to be a Therapeutic Cure on Day 28 ± 4), sample size is 
estimated for therapeutic equivalence of the Test to the Reference product. 
Based on data from a previous bioequivalence study conducted to support 
approval of the first generic product of permethrin cream, 5%, the 
Therapeutic Cure rate (pR) of the Reference product (Elimite™ permethrin 
cream 5%) is expected to be about 88% in the PP population. Assuming that 
the Therapeutic Cure rate for the Test group (pT) is an absolute difference of 
5% lower than the Therapeutic Cure rate for the Reference group (i.e., pT-
pR = -5%), a sample size of 107 patients in each active group in PP 
population will provide at least 90% power to demonstrate therapeutic 
equivalence (i.e., the 90% confidence interval [Yates’ continuity-corrected] 
on pT-pR  is within a defined equivalence range [-20% to +20%]). 
To allow for approximately 14% of patients who may drop out from the study 
or are otherwise non-evaluable, approximately 250 patients (125 in each 
treatment group) will be randomized, such that there will be an estimated 214 
patients (107 per group) in the PP population for statistical evaluation of 
therapeutic equivalence.

8.0 INTRODUCTION 
8.1 Disease Being Treated 
Scabies is an infestation of the skin by the human itch mite (Sarcoptes scabiei). The microscopic 
scabies mite burrows into the upper layer of the skin where it lives and lays its eggs. The most 
common signs and symptoms of scabies are intense itching, skin rash and the presence of tiny 
burrows caused by the female mites tunneling through the superficial surface of the skin. The scabies 
mite is spread by direct, prolonged, skin-to-skin contact with infected persons.1,2 
As of 2010, scabies affects approximately 100 million people (1.5% of the world population) and is 
equally common in both sexes. Scabies is found worldwide and affects people of all races and social 
classes. Scabies outbreaks are common in crowded public places, nursing homes, extended-care 
facilities, prisons and child care facilities.1,2 
Initial infections require 4-6 weeks to become symptomatic. Re-infection, however, may manifest 
symptoms within as few as 24 hours. Scabies symptoms are allergic, exhibiting a delay in onset as 
well as relief after the parasites have been eradicated. A more severe form of infection is crusted 
scabies, formerly known as Norwegian scabies, which is often associated with immunosuppression.1,2 
Diagnosis of scabies is made based on clinical symptoms, such as nocturnal itching and appearance 
and distribution of the rash. Definitive diagnosis includes the microscopic identification of the mite, 
mite eggs, or mite fecal matter in the skin. This can be done by carefully removing a mite or skin 
scraping from the end of its burrow (or near a lesion) using the tip of a needle and observing under a 
microscope.1,2 
8.2 Availability and Efficacy of Already Approved Therapies 
Food & Drug Administration (FDA)-approved scabies therapies, called scabicides are available only 
by prescription. Such treatments include topical medications such as permethrin cream 5% 
(Elimite™), crotamiton lotion/cream 10% (Eurax®, Crotan®) and lindane lotion 1%. Oral anti-
parasitic therapy includes ivermectin (Stromectol®), which is considered effective in combination 
with topical therapy.1,2 
Permethrin, a pyrethroid, is active against a broad range of pests including lice, ticks, fleas, mites, and 
other arthropods. It acts on the nerve cell membrane to disrupt the sodium channel current by which 
the polarization of the membrane is regulated. Delayed repolarization and paralysis of the pests are 
the consequences of this disturbance.  
Permethrin is considered the drug of choice for the treatment of scabies. It is safe for use in adults and 
children 2 months and older. One or two applications, about a week apart may be necessary to 
eliminate all mites and eggs on the patient’s body. 1,2 
8.3 Scientific and Statistical Considerations 
Permethrin is rapidly metabolized by ester hydrolysis to inactive metabolites which are excreted 
primarily in the urine. Although the amount of permethrin absorbed after a single application of the 
5% cream has not been determined precisely, data from studies with 14C-labeled permethrin and

Equivalence of Permethrin Cream, 5% (Encube Ethicals) Compared to Elimite™ Cream (permethrin) 5% 
(Prestium Pharma, Inc.) in the Treatment of Scabies 
 
 
Confidential Protocol 71675502  Rev 1  November 3rd, 2017  Encube Ethicals   Page 16 of 42 
 
 
absorption studies of the cream applied to patients with moderate to severe scabies indicate it is 2% or 
less of the amount applied. As the systemic absorption of the Reference product, Elimite™ cream 
(permethrin) 5% is extremely low , its relevance to clinical activity is not significant.3 A therapeutic 
efficacy evaluation based on relief from scabies symptoms and eradication of living mites     in the 
skin after using study products is considered the most appropriate methodology for this study.4,5 
A previous bioequivalence study conducted for the FDA marketing approval for the first generic 
product of permethrin cream, 5% indicated that the rate of clinical cure for this product and that for 
the Reference product, Elimite™ cream (permethrin) 5%, was about 88%; there was no placebo 
treatment arm in that study.6 
The design and sample size estimation for the study described in this protocol are based on a previous 
bioequivalence study. 
The FDA published a Draft Guidance on Permethrin Cream in October 2017,7 which was after the 
start of the conduct of study 71675502 (last patient, last visit occurred on October 30, 2017). 
Therefore, this protocol was revised to accommodate recommendations in that Guidance, as 
appropriate. Key revisions are the following: 
1. Revised definition of the per-protocol (PP) population to include those patients that are 
treatment failures on Day 14 as Therapeutic Failures in the final analysis (see section 11.3.1). 
2. Revised definition of the Safety population (see section 11.3.2). 
3. Removed the secondary efficacy endpoint (see section 11.5). 
4. Removed the Yates’ continuity correction for calculation of 90% confidence intervals on the 
absolute difference between the proportion of patients who are considered a Therapeutic Cure 
in the Test and Reference groups (see section 11.6). 
5. Added three supportive analyses to evaluate different evaluation windows for Visit 2 
(Day 14) and Visit 3 (Day 28) (see section 11.6). 
6. Added descriptive statistics for the number and frequency of re-infestations from Day 14 
(Therapeutic Cure) to Day 28 (Therapeutic Failure) in the PP population. 
The Guidance recommends a ± 2-day window for both the Day 14 and Day 28 visits. This protocol 
incorporates a ± 4-day window for both visits. The justification for the wider visit window is that 
permethrin cream 5% is expected to cure scabies infestation after a single treatment. That is, if it 
works by Day 14 it should still work by Day 28, and thus the re-infestation rate from Day 14 to 
Day 28 is expected to be low. Therefore, a wider visit window on Day 28 should be acceptable. The 
effect of different visit window durations at Day 14 and Day 28 will be explored in the three 
supportive analyses. 
The Guidance also recommends that the youngest patient (with scabies infestation who meets the 
inclusion criteria) from each household is considered to be the index or primary patient of the 
household for evaluation of the primary endpoint, that other members of the household and close 
contacts are enrolled as secondary patients (not included in primary endpoint analysis) and evaluated 
for all safety parameters, and that secondary patients should receive the same study treatment as the

index patient. This protocol did not define an index patient and secondary patients from each 
household. Instead all eligible household members that qualified for the study were separately 
randomized to receive study product (Test or Reference) and included in the primary endpoint 
analysis. The justification for this design is that there is no placebo treatment arm in this study; 
therefore, there is minimal chance that household members would exchange or share treatments, 
given that each enrolled member would receive active treatment. Because the risk of treatment 
exchange or sharing within a household is higher when some members receive active treatment and 
others receive placebo treatment, the Guidance-recommendation that primary and secondary subjects 
within a household all receive the same study treatment is necessary for a placebo-controlled study 
but is not necessary for an active-treatment-only study. 
9.0 STUDY OBJECTIVES 
The objectives of this study are to: 
1. Evaluate the therapeutic equivalence of the Test formulation, Permethrin Cream, 5% (Encube 
Ethicals) to the marketed product, Elimite™ Cream (permethrin) 5% (Prestium Pharma, Inc.) in 
patients with scabies. 
2. Compare the safety of Test and Reference treatments in patients with scabies. 
10.0 INVESTIGATIONAL PLAN 
10.1 Study Design and Plan Description 
This randomized, double-blind, parallel-design, multiple-site study is designed to evaluate the 
therapeutic efficacy and safety of a generic Permethrin Cream, 5% (Encube Ethicals) compared to the 
FDA Reference Listed Drug (RLD), Elimite™ Cream (permethrin) 5% (Prestium Pharma, Inc.) in 
patients with scabies. 
Before any study-specific procedures are performed, all patients will read and sign the IRB-approved   
informed consent that meets all criteria of current FDA and International Conference of 
Harmonisation (ICH) regulations. For patients who are considered minors in the state the study is 
being conducted (< 18 years in most states) the parent or legal guardian should sign the consent form 
and the child will be required to sign a patient “assent” form, as appropriate. Patients 11-17 years of 
age will read and sign an IRB-approved assent form and patients 6-10 years of age will provide verbal 
assent. Patients 2-5 years of age will be exempt from providing assent based on the child’s 
comprehension and cognitive skills.  
Approximately 250 eligible patients, 2 years of age and older with a clinical diagnosis of active 
scabies based on signs and symptoms and confirmation of microscopic evidence of scabies mites in 
the skin will be randomized in a 1:1 ratio (Test: Reference) to one of the two study products as 
follows: 
• 
Test: Permethrin Cream, 5%, (Encube Ethicals) 
• 
Reference: Elimite™ Cream (permethrin) 5% (Prestium Pharma, Inc.*)

Patients will be instructed to self-administer a single dose of study product or, if patient is a child, 
then parent/guardian will apply study product to him/her on Day 1 according to the dosing 
instructions provided. A second application may be required if presence of scabies infestation is 
microscopically demonstrated (i.e., living mites, viable mite eggs, or mite fecal matter present) at 
Visit 2. The second dose will be self-administered by the patient or if patient is a child, then 
parent/guardian will apply study product to him/her on the evening of Visit 2. Eligible household 
members and close contacts of the patient who were in need of treatment will be offered generic 
permethrin cream as a method to reduce cross-contamination within a household. Additionally, 
household members will be requested to follow the standard hygiene practices. Patients whose 
household members are not willing to comply with the standard of care for Scabies management (i.e., 
use of generic permethrin cream and standard hygiene practices) will not be enrolled in the study.  
During the study, patients will visit the clinical center for a total of three scheduled visits: 
• 
Visit 1 (Day 1): Screening/Baseline 
• 
Visit 2 (Day 14 ± 4): Interim Visit 
• 
Visit 3 (Day 28 ± 4): End of Study or Early Termination 
Final assessments will be carried out at Visit 3 (Day 28 ± 4), which is the test-of-cure visit. The test-
of-cure visit will occur 4 weeks (± 4 days) after the end of the single application treatment on study 
Day 1 or 2 weeks (± 4 days) after the end of a second application, if necessary, on Day 14 ± 4. 
Therapeutic cure of scabies will be evaluated based on microscopic evidence of absence of scabies 
infestation (i.e., no living mites, no viable mite eggs, and no mite fecal matter), visual evidence of 
absence of new lesions, and healing of original lesions, regardless of the presence of post-scabetic 
nodules (i.e., post-scabetic nodules need not be considered as new lesions or persistence of old 
lesions). The primary statistical analysis of interest is the proportion of patients in each treatment 
group with Therapeutic Cure (parasitological cure plus clinical cure) of scabies 
10.2 Selection of Study Design 
This study has been designed based on information provided in the Summary Basis for Approval of 
permethrin cream, 5% (Alpharma, U.S. Pharmaceuticals Division) and prescription information for 
the Reference product, Elimite™ cream (permethrin) 5%.6 
Statistical analyses of the clinical data will be based on recommendations in FDA Guidances.5,7-10 
Details of the analyses will be outlined within the Statistical Analysis Plan (SAP).

10.3.3 Restrictions During the Study 
Patients will be instructed to refrain from the following treatments throughout the study: 
• 
Any other prescription/over-the-counter (OTC)/natural/herbal scabicides. 
• 
Systemic and topical corticosteroids or immunosuppressants (e.g., high dose of systemic 
corticosteroids, systemic calcineurin inhibitors, Azathioprine). 
• 
Prolonged exposure to sunlight/UV, use of tanning beds, chemical treatments/peels, 
dermabrasion or any dermatological procedures that will potentially influence or hinder 
the evaluation of scabies signs and symptoms. 
Note: Use of antibiotics (systemic and topical) for cutaneous bacterial infections during the 
conduct of the study will be allowed after the Screening/Baseline visit, but the usage should be 
restricted to the Principal Investigator’s discretion in cases of secondary infections of scabietic 
lesions. The usage of the antibiotic should be included on the concomitant medication page. 
10.3.4 Removal of Patients from the Study 
Patients will be advised that they are free to withdraw from the study at any time for any reason 
or, if necessary, the Investigator may withdraw a patient from the study to protect the health of 
that patient. A patient may also be withdrawn for not complying with study procedures. The 
clinical report will include all reasons for early withdrawals. 
Reasons for removal may include, but are not limited to the following: 
•

• 
Non-compliance with protocol including the use of restricted medication 
• 
Pregnancy 
• 
Significant worsening of scabies such that the Investigator and/or patient believes it is in 
the best interest of the patient to withdraw from the study and be provided alternative 
treatment 
• 
Participant enrolls in another clinical trial, or is found to have previously enrolled in this 
study 
10.3.5 Early Terminations 
If a randomized patient terminates from the study early, all efforts will be made to complete the 
End of Study procedures. For early termination the Investigator will fully document the reason 
for early termination. 
10.4 Treatments 
10.4.1 Treatment Administration 
Patients will be provided with verbal and written instructions on how to administer the study 
product. Eligible household members and close contacts of the patient will be offered permethrin 
cream (if they are in need of treatment) and will follow the appropriate application and 
decontamination instructions as follows. Patients whose household members are not willing to 
comply with the standard of care for Scabies management (i.e., use of generic permethrin cream 
and standard hygiene practices) will not be enrolled in the study. 
Patients will be instructed to thoroughly massage study product into (clean) skin from the head to 
the soles of the feet, including all folds, interdigital space, groin, navel, and external genitalia, as 
well as the skin under nails and jewelry (i.e., rings, watches). Scabies rarely infests the scalp of 
adults, although the hairline, neck, temple, and forehead may be infested in infants and geriatric 
patients. Usually 30 grams is sufficient for an average adult. Patients must NOT wash their hands 
from the time the product is applied until the time the product is removed. Study product should 
be reapplied if hands are washed after application. Scabies rarely infests the scalp of adults, 
although the hairline, neck, temple, and forehead may be infested in toddlers and geriatric 
patients. For toddlers, only the following areas on the head should be treated: the scalp, temple, 
and forehead, avoiding the eyes, because transmission of mites may potentially occur during 
breastfeeding.  Clean clothing should be worn after product application. The cream should be 
removed by washing (shower or bath) after 8 to 14 hours. Contact with eyes during application 
must be avoided. Eyes should be flushed with water immediately if the study product gets in the 
eyes.  
On Day 1, before applying treatment, all bedding, clothing, and towels used by infested persons 
or their household, sexual, and close contacts should be decontaminated by washing in hot water 
and drying in a hot dryer, by dry-cleaning, or by sealing in a plastic bag for at least 72 hours.

Confidential Protocol 71675502  Rev 1  November 3rd, 2017  Encube Ethicals   Page 22 of 42 
 
 
Instructions on good hygiene and proper methods of decontamination will be provided to the 
patient. 
Patients may experience persistent pruritus after treatment. This is not to be considered a sign of 
treatment failure and is not an indication for retreatment. Demonstrable living mites (i.e., living 
mites, viable mite eggs, or mite fecal matter) on at Visit 2 indicate that re-treatment is necessary. 
Retreatment should occur the evening of Visit 2. 
 Standard anti-itch medication (oral hydroxyzine capsule or oral solution) will be provided by the 
Investigator, as deemed necessary based on his/her judgment, for the relief of intolerable itching, 
or to facilitate nighttime sleep during the treatment period (when the itching severely affects 
sleep). Frequent use of the anti-itch medication is not encouraged. Suggested dosing for patients 
> 12 years old is 25 mg per os every 6-8 hours as needed or at hora somni; the maximum dosage 
allowed is 100 mg/24 h. For patients ≥ 2 years old is 2 mg/kg/day per os divided every 6-8 hours 
as needed; the maximum dosage allowed is 50 mg/24 h. Patients will be required to record the use 
(date, time and dose) of rescue medication in the patient diary. 
Skin sores that become infected may be treated with an appropriate antibiotic provided by the 
Investigator if such decision is made based on the clinical picture and at the discretion of the 
Investigator. 
10.4.2 Identity of Investigational Product 
The following products will be used in the study: 
• 
Test: Permethrin Cream, 5% (Encube Ethicals) 
• 
Reference: Elimite™ Cream (permethrin) 5% (Prestium Pharma, Inc.*) 
10.4.3 Study Product Shipment, Storage, and Retention 
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 20-25°C (68-77°F) [USP Controlled 
Room Temperature]. Any excursions from the permitted range of 15–30ºC (59º–86ºF) will 
require prompt notification to Novum, and thereafter Novum will notify the Sponsor. 
For every study product shipment received at the site, the Investigator (or designee) will 
randomly select at least one block of study product for retention. The selection process will 
ensure a sufficient amount of retention samples are retained as per Sponsor requirement (i.e., 
amount needed for 5x release testing). Each kit in the block selected for retention will be labeled 
as a retention sample and should not be dispensed to study patients. The selected retention 
samples will be retained by each site under FDA regulations as study retention samples.11 
Once the site has been notified that they may do so, all unused study product and empty or 
partially used tubes of study product, other than that randomly selected for retention samples will

be returned to the Sponsor or designee. It is important that retention samples not be returned to 
Novum, the Sponsor or the packaging company during or at the end of the study. 
10.4.4 Method of Assigning Patients to Treatment Groups 
The study product will be randomized, packaged and blinded by an independent packaging 
company. Randomization will be pre-planned according to a computer-generated randomization 
schedule. All randomized study products will be blinded and packaged in sealed boxes. Each 
block will contain two patients’ worth of product (1 Test and 1 Reference). Each patient kit will 
include 1 x 60 gram tube of study product, which should be sufficient for full treatment. 
The randomization number will be a unique four-digit number. Patient numbers will be assigned 
immediately before dispensing of study product and in ascending sequential order, beginning 
with the lowest available number at the study site. Each patient kit and each dispensed study tube 
should include the four-digit patient number on the label. 
At the end of the study, after all the clinical data have been entered and the study database has 
been locked, a copy of the randomization schedule will be sent to the statistician. 
10.4.5 Study Blind 
The Investigator, staff at the study site, study monitors, and data analysis/management personnel 
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 study product to/from 
the patients, maintain dispensing records, and ensure the study product logs are complete and 
accurate. The patient will be requested not to discuss the appearance of the study product with the 
Investigator or study staff. 
A perforated or two-part label will be attached to the study product supplies for each patient. One 
part of the label will remain attached to the box. This part should include the following 
information: 
• 
Protocol number 
• 
Randomization number 
• 
Space for patient’s initials 
• 
Caution New Drug limited by federal law to investigational use 
• 
Space for dispensing date, storage information, general directions and the Sponsor’s 
name 
The other part will be removed before dispensing and attached to patient’s source documentation. 
To ensure information that could potentially bias handling of data is not disclosed, the clinical 
packaging company will hold the randomization scheme until database lock.  For each patient  the 
tear off portion of the label will have a concealed scratch off area describing the assigned 
treatment, to be unblinded only in the case of medical emergency and should be kept at the site 
with the study documents when the study is completed.

documents in the event of an FDA inspection.   
10.4.6 Compliance 
Patients will be provided with a diary to record the time and date of dosing, concomitant 
medications and AEs. Use of restricted medications will be reviewed based on patient diary 
entry(s) and verbal discussion with the patient. Dosing compliance will be checked based on the 
dosing diary entry and verbal discussion with the patient at Visits 2 and 3 (when applicable). 
Patients will be considered compliant with dosing if they administer 100% of the required number 
of doses (i.e., one or, if necessary, two doses).

10.6 Study Procedures 
10.6.1 Informed Consent 
At Visit 1, before performing any study-related procedures, patients should sign informed consent 
that meets all criteria of current FDA regulations. For patients who are considered minors in the 
state the study is being conducted (< 18 years in most states) the parent or legal guardian should 
sign the consent form and the child will be required to sign a patient “assent” form, as 
appropriate. Patients 11-17 years of age will read and sign an IRB-approved assent form and 
patients 6-10 years of age will provide verbal assent. Patients 2-5 years of age will be exempt 
from providing assent based on the child’s comprehension and cognitive skills.  
10.6.2 Medical History and Demographics 
At Visit 1, each patient will be required to provide basic demographic information: date of birth, 
gender, ethnicity and race. Patients will also be questioned about medical history, including acute 
and chronic medical history and medical history relevant to their scabies. 
10.6.3 Vital Signs 
At Visit 1 and at the end of the study (Visit 3 or early study termination as appropriate), sitting 
blood pressure, pulse, respiration rate and temperature will be recorded. 
10.6.4 Adverse Events 
At Visit 1, patients will be questioned about any changes in patient’s health status, including 
occurrence of AEs since signing the ICF or Assent or AEs that may have occurred during the 
visit. All AEs will be recorded. At Visits 2 and 3 patients will be questioned regarding any 
changes in their medical status since their previous visit. Any changes will be reported as AEs. 
10.6.5 Concomitant Medication 
At Visit 1, patients will be questioned about current and prior medication use over the previous 6 
months. At Visits 2 and 3 patients will be questioned about ongoing or any new concomitant 
medication use.

10.6.6 Microscopic Examination 
At each clinic visit, the Investigator will conduct a dermatological examination to identify living 
mites in the skin. A dermoscope can be used (but is not required) to observe 
lesions/papules/blisters/burrows on the skin. Once determined that the lesions are characteristic of 
scabies, the Investigator will collect a skin scraping sample for identification of living 
mites/eggs/feces by light microscopy. See Appendix B for details. 12-14 
10.6.7 Scabies Signs and Symptoms Rating 
At each clinic visit, patients will be asked to rate the severity of nocturnal pruritus using a 4-point 
scale for pruritus severity. Investigators will be asked to complete a rating scale to record severity 
of lesion count infestation (Appendix A).15 
10.6.8 Pregnancy Test 
All females of childbearing potential will have a urine pregnancy test performed at Visits 1 and 3. 
The test must be negative at Visit 1 for the patient to be eligible for inclusion in the study. If the 
patient is of non-childbearing potential, the source document must list the reason why she is of 
non-childbearing potential (e.g., postmenopausal). 
Any patient who becomes pregnant during the study must be discontinued and End of Study 
procedures completed. The outcome of the pregnancy will be followed by the Investigator to birth 
or early termination as appropriate. The pregnancy will be reported as an AE. 
10.6.9 Review Inclusion/Exclusion Criteria 
At Visit 1, inclusion/exclusion criteria will be reviewed to ensure patients’ eligibility for 
participation in the study. 
10.6.10 Collect and Review Patient Diary 
At Visits 2 and 3, patient diaries will be collected and reviewed for compliance with the protocol. 
10.6.11 Provide Patient Diary 
Patients will be given a diary with instructions on dosage administration and diary completion. 
The diary will be reviewed by the study staff at Visits 2 and 3 (when applicable). 
10.6.12 Dispense Study Product 
After the Investigator has determined that the study participant meets the inclusion/exclusion 
criteria for the study the “Independent Dispenser” will dispense one 60 gram tube of study 
product to the patient using the lowest patient randomization number available at that 
investigative site, and if necessary, at Visit 2 (re-dispense the same tube to the patient, i.e., no 
new tube will be provided) with dosing instructions. The Independent Dispenser will ensure the 
study product logs are reported correctly. Eligible household members and close contacts of the 
patient will be administered generic Permethrin cream and will follow the appropriate application 
and decontamination instructions.

10.6.13 Collect and Weigh Study Product 
Study product tubes will be collected and weighed at Visit 2 or Visit 3 (in cases when re-
treatment is required or if the patient inadvertently did not return the study product at Visit 2) by 
the Independent Dispenser and checked for compliance or evidence of tampering with the blind. 
The weight will be recorded in the drug accountability log. 
10.7 Adverse Events 
The patients will be monitored throughout the study for any AEs. Adverse events will be collected 
through both solicited and unsolicited means and subsequently coded in tabular form using the 
Medical Dictionary for Regulatory Activities (MedDRA) (Version 20.0 or higher) AE 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. AEs should 
be followed up until they have resolved or stabilized. 
10.7.1 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 AE 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 insert/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 AE is at least a reasonable 
possibility, i.e., the relationship cannot be ruled out. 
10.7.2 Severity of Adverse Event 
The severity of the AE 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. 
10.7.3 Relationship of Adverse Event 
Relationship to the study product will be evaluated by the Investigator as follows:

• 
Not Related: A causal relationship between the study treatment and the AE is not a 
reasonable possibility 
• 
Related: A causal relationship between the study treatment and the AE is a reasonable 
possibility. 
10.8 Serious Adverse Events 
10.8.1 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). 
Emergency Room visits that require medical or surgical intervention to prevent one of the 
other serious outcomes listed above are considered an SAE. 
10.8.2 Reporting Serious Adverse Events 
Investigator Reporting of SAEs 
Adverse events that meet the above criteria for "Serious" will be reported to the Sponsor and IRB 
within 24 hours of notice whether or not they are considered expected or drug-related. All SAEs 
will be reported as per applicable regulations. All SAEs encountered during the study will be 
reported on the appropriate form and summarized in the final report. 
Any serious or unexpected AEs should be reported to Novum within 24 hours. Following is

Novum will be responsible for notifying the FDA of any SAEs. Novum must notify FDA of fatal 
or life-threatening SAE as soon as possible, but no later than seven calendar days from reporting 
the event by the Investigator. 
Novum will inform all the participating investigators of any SAEs reported at other study sites 
within 15 days from the initial report. Sites outside of the US will be responsible for reporting to 
their local regulatory authorities as appropriate. 
11.0 STATISTICAL METHODS 
11.1 Statistical Plan 
A Statistical Analysis Plan (SAP), detailing the intended statistical analyses of the study data, will be 
prepared as a separate document and finalized before database lock. Any deviation from the original 
SAP 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. 
All statistical analyses will be performed by Novum Pharmaceutical Research Services and conducted 
using the Statistical Analysis System (SAS®), Version 9.4 or higher. Datasets will be prepared using 
headings from Clinical Data Interchange Standards Consortium (CDISC) Study Data Tabulation 
Model (SDTM) implementation for human clinical trials and Analysis Dataset Model (ADaM). 
11.2 Determination of Sample Size 
For the primary endpoint analysis (proportion of patients in the PP population who are considered to 
be a Therapeutic Cure on Day 28 ± 4), sample size is estimated for therapeutic equivalence of the 
Test to the Reference product. 
Based on data from a previous bioequivalence study conducted to support approval of the first generic 
product of permethrin cream, 5%, the therapeutic cure rate (pR) of the Reference product (Elimite™ 
permethrin cream 5%) is expected to be about 88% in the PP population. Assuming that the 
Therapeutic Cure rate for the Test group (pT) is an absolute difference of 5% lower than the Reference

group (i.e., pT-pR = -5%), a sample size of 107 patients in each active group in PP population will 
provide at least 90% power to demonstrate therapeutic equivalence (i.e., the 90% confidence interval 
[Yates’ continuity corrected] on pT-pR is within a defined equivalence range [-20%, +20%]). 
To allow for approximately 14% of patients who may drop out from the study or are otherwise non-
evaluable, approximately 250 patients (125 in each treatment group) will be randomized, such that 
there will be an estimated 214 patients (107 per group) in the PP population for statistical evaluation 
of therapeutic equivalence.  
11.3 Study Populations 
11.3.1 Per-Protocol Population 
The PP population will include: 
• 
Met the inclusion/exclusion criteria as defined in this protocol at Visit 1. 
• 
Did not take any prohibited medications throughout the study. 
• 
Did not have any significant deviations from the protocol. 
• 
Did not develop any concurrent dermatological condition or illness exhibiting symptoms 
similar to scabies, or symptoms that in the Investigator’s opinion would interfere with 
endpoint assessments. 
• 
Completed the last study visit (Visit 3) Day 28 ± 4. 
Patients will be included in the PP population as treatment failures in the final analysis on Day 28 
(provided they had no significant protocol deviations) if they 1) withdrew from the study because 
of lack of efficacy, 2) show therapeutic cure at Day 14 ± 4 but re-infestation at Day 28 ± 4, or 3) 
do not respond to the initial treatment and have new lesions or microscopic confirmation of mites, 
ova, or fecal matter on Day 14 ± 4. 
11.3.2 Safety Population 
The safety population will include all patients who are randomized who applied at least one dose 
of the assigned study product. 
11.4 Baseline Comparability 
Baseline comparability of all treatment groups will be evaluated separately in the PP and Safety 
populations. 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)

Summary tables by treatment group will be presented. Continuous variables will be summarized 
using descriptive statistics (number of observations, median, minimum, maximum, mean and standard 
deviation). Categorical variables will be summarized using frequencies and percentage. Baseline 
treatment comparisons will be presented using Chi-Square or Cochran-Mantel-Haenszel (CMH) tests 
for the categorical variables, and Analysis of Variance (ANOVA) for the continuous variables. 
All data will be listed by treatment and patient. 
11.5 Efficacy Endpoint 
The primary efficacy endpoint is the proportion of patients in each treatment group with Therapeutic 
Cure (parasitological cure plus clinical cure) of scabies at the test-of-cure visit conducted at 
Day 28 ± 4. A parasitological cure is defined as failure to demonstrate microscopically the presence 
of scabies infestation (i.e., no living mites, no viable mite eggs, and no mite fecal matter present). A 
clinical cure is defined as visual evidence of absence of new lesions and healing of original lesions, 
regardless the presence of post-scabietic nodules (i.e., post-scabietic nodules need not be considered 
as new lesions or persistence of old lesions). 
Patients who do not respond to the initial treatment and have new lesions or microscopic confirmation 
of mites, ova, or fecal matter on Day 14 ± 4 will be treated as treatment failure in the final analysis on 
Day 28.  
11.6 Efficacy Analyses 
Primary Analysis: 
Therapeutic equivalence of the Test product to the Reference product based on the primary endpoint 
will be evaluated in the PP population. If the 90% confidence interval on the absolute difference 
between the proportion of patients who are considered a Therapeutic Cure (primary) in the Test and 
Reference groups is contained within the range [-20%, +20%] then therapeutic equivalence of the 
Test product to the Reference product will be considered to have been demonstrated. 
Supportive Analyses: 
The following supportive analyses will be performed for the primary endpoint: 
1. The primary analysis will be performed including patients who completed Visit 2 within 
14 ± 2 days and Visit 3 within 28 ± 4 days. 
2. The primary analysis will be performed including patients who completed Visit 2 within 
14 ± 2 days and Visit 3 between Day 26 and Day 32, inclusive. 
3. The primary analysis will be performed including patients who completed Visit 2 within 
14 ± 2 days and Visit 3 within 28 ± 2 days. 
To declare therapeutic equivalence of the Test product to the Reference product, therapeutic 
equivalence must be demonstrated for only the primary analysis.

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 for the primary 
efficacy endpoint in the PP population (for equivalence testing). The treatment-by-site interaction will 
be evaluated by the Breslow-Day test for homogeneity of the odds ratio at the 5% significance level 
(p < 0.05). A site(s) with a low enrollment rate(s) may be pooled with its geographically closest site, 
so as to avoid bias in the estimation of a treatment-by-site interaction effect. The pooling will be done 
for low enrolling sites that account for less than 4-7% of the total number of patients in the PP 
population at the site with the highest enrolling rate in the PP population. If the treatment-by-site 
interaction term is found to be statistically significant (p < 0.05) for the primary endpoint, then the 
interaction term will also be assessed for clinical relevance before pooling the data across sites. This 
will include examination of Therapeutic Cure rates at each site where sample sizes per treatment may 
be influential in the assessment of the interaction. 
11.8 Safety Analysis 
Adverse events will be classified using standard MedDRA terminology Version 20.0 or higher and 
summarized by treatment group. Summary tables comparing the type, incidence, date of onset, date of 
resolution, severity, action taken, outcome and Investigator’s opinion of relationship to the study 
product will be prepared by treatment group. If sufficient data exist, AE frequencies will be compared 
between treatments using Fisher’s exact test or a similar test in the Safety population. 
Signs and symptoms of scabies 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/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. 
Concomitant medication use during the study will be tabulated by patient. 
12.0 REGULATORY OBLIGATIONS 
12.1 Institutional Review Board 
The study protocol, ICF, Investigator's Brochure, or package insert (as applicable), and any specific

12.2.1 Protocol 
The Investigator indicated on FDA Form 1572 will act as the Principal Investigator at each study 
site. Protocols will be noted as approved by placement of the Novum Representative’s signature 
on the cover page. The Sponsor of the study will also approve the protocol by having a study-
responsible individual sign the protocol cover page. The Principal Investigator will sign the 
protocol signature page indicating their agreement to conduct the study according to the protocol. 
12.2.2 Informed Consent 
An ICF that includes all of the relevant elements currently required by FDA, ICH, and local state 
regulations will be provided to each prospective study patient before enrollment into the study. 
The type and method of study, tests to be administered, any potential or possible hazards, and the 
patient's right to withdraw from the study at any time will be explained to the patients 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 patient 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 patient has indeed received information. If any other language is required, 
translation will be performed by a certified translator. A copy of the ICF will be provided to the 
patient. For patients who are considered minors in the state the study is being conducted (< 18 
years in most states) the parent or legal guardian should sign the consent form and the child will 
be required to sign a patient “assent” form, as appropriate. Patients 11-17 years of age will read 
and sign an IRB-approved assent form and patients 6-10 years of age will provide verbal assent. 
Patients 2-5 years of age will be exempt from providing assent based on the child’s 
comprehension and cognitive skills. 
12.2.3 Protocol and Informed Consent Changes 
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 
patient requires the patient’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. 
12.2.4 Source Documents and Electronic Case Report Forms (eCRF) 
All patients will be identified by initials, date of birth and a unique patient number. Source 
documents will be used to record all study-related data. Source document entries will be used to 
complete eCRFs. A set of eCRFs will be completed for each patient randomized in the study. All 
data and eCRFs will be reviewed, evaluated and signed by the Investigator. 
The original source documents and a copy of the corresponding eCRFs will be retained by the 
Investigator. Patients who terminate early from the study will have the Visit 3 (End of Study) 
source/eCRF completed.

12.2.5 Drug Accountability 
All study product receipt, inventory, dispensing, dosing and reconciliation records will be 
maintained in compliance with federal regulations. The study product will be dispensed to 
qualified study patients according to established procedures. At the end of the study (after the 
database has been locked) all used and unused study product will be returned to Sponsor or 
designee. 
12.2.6 Drug Storage 
Study product will be stored at controlled room temperature 20-25°C (68-77°F) [USP Controlled 
Room Temperature] in a secure place with access by authorized individuals only. The 
Investigator will be responsible for maintaining accurate records of drug receipt, dispensing, and 
return. After finalizing the study report, all partially used and unused study product will be 
returned to Sponsor or designee. 
12.2.7 Retention of Reserve Samples 
For every study product shipment received at the Investigator site, the Investigator (or designee) 
will randomly select at least one block of study product for retention, unless otherwise instructed 
by the Sponsor and/or Novum. These retention samples should be stored under the appropriate 
storage conditions for a minimum of 5 years following the application approval or, if not 
approved, at least 5 years after the completion of the study. Retention samples should not be 
returned to Sponsor/CRO/packaging group at any time. 
12.2.8 Pregnancies 
Patients with a positive pregnancy test during screening will not be enrolled in the study. Patients 
who report that they have become pregnant during the study or have a positive pregnancy test at 
Visit 3 will be followed to completion of the pregnancy. The pregnancy will be reported as an 
AE. 
Female patients of childbearing potential must have been using and must agree to continue to use 
accepted methods of birth control, throughout the study. Acceptable methods of birth control 
include total abstinence, intrauterine device, a double-barrier method (such as condom with 
spermicide or diaphragm with spermicide), oral, transdermal, injected, or implanted non-
hormonal or hormonal contraceptive throughout the study. Female patients using hormonal 
contraceptives should have been on the same product/dosing regimen for at least 28 days before 
Visit 1 and should not change this regimen during the study. A sterile sexual partner is not 
considered an adequate form of birth control. Before study enrollment women of childbearing 
potential must be advised of the importance of avoiding pregnancy during study participation. 
A negative result of a urine pregnancy test having a minimum sensitivity of at least 50 mIU/mL 
for human chorionic gonadotropin (hCG) should be obtained, before study participation. 
Pregnancy testing will be performed at Visits 1 and 3 and the results of all pregnancy tests 
(positive or negative) will be documented.

If following initiation of study treatment, it is subsequently discovered that a study patient is 
pregnant or may have been pregnant at the time of study product exposure, the study product will 
be permanently discontinued. The Principal Investigator or designee must immediately notify the 
Medical Monitor of this event. Reporting timelines and Novum/Sponsor contact will be 
consistent with SAE reporting guidelines (i.e., pregnancies will be reported to the 
Sponsor/Novum within 24 hours to the contacts listed in section 10.8.2). 
Protocol-required procedures for study discontinuation and follow-up must be performed on the 
patient. Other appropriate pregnancy follow-up procedures should be considered if indicated. All 
follow-up information regarding the course of the pregnancy, including perinatal and neonatal 
outcome will be communicated as per the above guidelines. Infants should be followed for a 
minimum of eight weeks after birth. 
12.2.9 Reporting Safety Information to the IRB 
The Investigator must promptly report to the Investigator’s IRB all unanticipated problems 
involving risks to patients. This includes death from any cause and all SAEs occurring during the 
study, regardless of the assessed causality.20 
12.2.10 Record Retention 
All drug accountability records, eCRFs, source data and related regulatory documents must be 
retained for at least two years following completion of the study or Test product approval for 
marketing by the FDA. 
12.2.11 Study Monitoring and Auditing 
Novum will be responsible for monitoring the study according to GCP and applicable regulations. 
Monitoring visits are for the purpose of confirming adherence to the protocol and to verify 
complete and accurate data collection. The clinical site will make all records associated with the 
study available to Novum’s representative during such visits and audits. 
The study may be subject to audit by the Sponsor, Sponsor Representative or by regulatory 
authorities. If such an audit occurs the Investigator must agree to allow access to required patient 
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. 
12.2.12 End of the Trial 
The end of the trial is defined as the time at which the last patient has completed their last visit in 
the study. Upon completion of the study, the study product will no longer be available to the 
patient but the Investigator can, at their discretion, discuss alternative treatments with the patient. 
12.2.13 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

14.0 APPENDICES 
14.1 APPENDIX A: RATING OF SCABIES SIGNS AND SYMPTOMS 
PRURITUS 
At each clinic visit, patients will be asked to rate the severity of pruritus (overall itch intensity and 
effect of itching on nighttime sleep) on the following 4-point scale. 
  
0 = none (complete absence of itching) 
 
1 = mild (slight itching, no sleep loss) 
 
2 = moderate (definitely present, interrupts sleep) 
 
3 = severe (marked, intense, cannot sleep) 
LESION COUNT 
At each clinic visit, the lesion count will be evaluated and rated as follows: 
 
< 50 = mild 
 
50-100 = moderate 
> 100 = severe

14.2 APPENDIX B: DERMOSCOPY AND MICROSCOPY FOR SCABIES DIAGNOSIS 
SKIN SCRAPING/MICROSCOPY 
Skin scrapings will be obtained with a sterile scalpel after the application of 1 drop of mineral oil onto 
the lesion. The scraped material will be transferred to a slide and covered with a cover slip. Reading 
is to be performed immediately under a microscope, or within 3 hours, at 40 X magnification. The 
number of scraped sites until the examination is declared negative will be left to the recognition of the 
attending Investigator in relation to the clinical picture. 
A single scraping is not considered sufficient to adequately define parasitological cure. 
 
The best efforts should be made to attempt valid skin scrapings for microscopic examinations, even in 
case of virtually healed lesions as appropriate.
