SYNOPSIS 
Name of Sponsor/Company: Hill Dermaceuticals, Inc. 
Name of Finished Product: Miconazole oil 
Name of Active Ingredient: 2% miconazole 
Study Title: 
Randomized, Double-blind, Phase III Study of the Efficacy and Safety of Miconazole Oil 
versus Vehicle Oil in the Treatment of Otomycosis, Followed by an Open-label Safety 
Evaluation 
Study Number: MZ-0120-ESP3-052 
Study Center(s): Up to 20 study centers in the United States (US) 
Number of Subjects Planned:  
Approximately 390 (estimated); the actual number enrolled will be the number needed to 
achieve at least 128 subjects eligible to be included in the modified intent-to-treat (MITT) 
population, defined as all subjects who were randomized with a positive fungal culture at 
Screening/Baseline, and to achieve at least 300 subjects exposed to miconazole oil for 14 
days who are evaluable for safety. Thus, a higher or lower number than estimated may be 
enrolled, with enrollment continuing until the required numbers of subjects have been 
achieved. 
Phase of Development: 3 
Objectives: 
• Confirm the efficacy of miconazole oil compared with vehicle over a 14-day treatment 
duration in subjects with otomycosis 
• Assess the safety of miconazole oil over a 14-day treatment duration  
Design and Methodology: 
This study will be conducted in 2 portions: 
1. Enrollment A, which will consist of 2 treatment periods as follows and will be conducted in 
subjects with otomycosis: 
a. A randomized, double-blind, parallel-group treatment period. This treatment period will 
be referred to as the “Randomization Period” and will be followed by: 
b. An optional, open-label treatment period with miconazole oil. This treatment period will 
be referred to as the “Optional Open-label Extension.” 
2. Enrollment B, which will consist of open-label treatment with miconazole oil in subjects who 
will not be required to have signs and symptoms of otomycosis. 
Enrollment A 
The study will start with Enrollment A, in which an estimated 220 male or female subjects with 
otomycosis will receive study drug, although this number may be higher or lower depending on 
the percentage of subjects eligible to be included in the MITT population. Subjects will be 
randomly assigned in a 1:1 ratio to receive miconazole oil or vehicle, for 14 days. The study 
drug will be administered as 5 drops per ear at ~30 mg per drop instilled into the external ear 
canal of the ear(s) affected by otomycosis. 
Randomization Period 
During the Randomization Period, both the subject and the investigator and study staff will be 
blinded as to the contents of the study drug.

At Screening/Baseline (Day 1), potentially eligible subjects will provide informed consent, and 
subjects will undergo screening evaluations to include a physical examination, an assessment 
of the signs and symptoms of otomycosis (pruritus, debris, visual examination for presence of 
fungal elements, and aural fullness), and an evaluation of medical history. Urine will be 
obtained for pregnancy screening in female subjects of childbearing potential. Prior and 
concomitant medications will be reported. Subjects with positive signs and symptoms of 
otomycosis and who meet all other eligibility criteria will be entered into the study. A fungal 
culture of the affected ear(s) will be taken, then debris will be cleaned from the affected ear(s) 
following the site’s normal procedures. The subject will be randomized, and study drug will be 
weighed and dispensed to the subject along with a subject diary. The subject will then begin 
treatment with study drug. The subject or caregiver will instill the first dose of study drug at the 
site, under the supervision of the investigator or site personnel. Adverse events (AEs) will then 
be assessed. The subject will then leave the clinic and continue to administer the study drug 
and to complete the subject diary twice per day as instructed. Subjects will be instructed to 
avoid getting water in the ear, to consider drying excessive water in the ear by using a blow 
dryer, and to place a Vaseline-impregnated cotton ball over the affected ear(s) to help keep 
water out of the ear while bathing or showering. 
Subjects will return to the clinic on Day 8 for the On Treatment Visit, at which time a clinical 
evaluation of the signs and symptoms of otomycosis, a cleaning of the affected ear(s) 
(following the site’s normal procedures), a review of the subject diary, and an assessment of 
AEs and concomitant medications will be performed. Subjects will continue to administer the 
study drug and to complete the subject diary twice per day, up through Day 14, following the 
same instructions as provided at the Screening/Baseline Visit on Day 1. 
Subjects will return to the clinic on Day 15 for the End of Treatment Visit, at which time a 
clinical evaluation of the signs and symptoms of otomycosis and a fungal culture of the 
affected ear(s) will be performed; however, a fungal culture will not be required at this visit for 
subjects known to have a negative fungal culture at Screening/Baseline, as assessed after at 
least 14 days of incubation by the clinical laboratory performing the fungal culture. AEs and 
concomitant medications will also be assessed, and the subject will return all unused study 
drug along with the completed subject diary.  
Subjects will return to the clinic on Day 22 for the Test of Cure Visit, at which time an 
assessment of clinical signs and symptoms of otomycosis and a fungal culture of the affected 
ear(s) will be performed; however, a fungal culture will not be required at this visit for subjects 
known to have a negative fungal culture at Screening/Baseline, as assessed after at least 14 
days of incubation by the clinical laboratory performing the fungal culture. AEs and 
concomitant medications will also be assessed. A urine pregnancy test will be performed in 
women of childbearing potential. 
Optional Open-label Extension 
Subjects who either complete the Randomization Period of the study (up through the Test of 
Cure Visit), or who are prematurely discontinued from study treatment during the 
Randomization Period due to worsening of signs and/or symptoms of otomycosis in the 
judgment of the investigator, will be offered the opportunity to participate in an optional open-
label extension, if they have a visual presence of fungal elements in at least one ear treated 
during the Randomization Period. Only the ear(s) that were treated in the Randomization

Period will be potentially eligible for treatment during the Optional Open-label Extension. 
All subjects in the Optional Open-label Extension will receive miconazole oil for 14 days. No 
unblinding of the subject’s treatment in the Randomization Period will occur at this time. 
Before a subject enters the Optional Open-label Extension, all procedures for the Test of Cure 
Visit will be completed for that subject; however, a fungal culture will not be required at this 
visit for subjects known to have a negative fungal culture at Screening/Baseline, as assessed 
after at least 14 days of incubation by the clinical laboratory performing the fungal culture.  
At the first visit of the Optional Open-label Extension (Day OLE1, which will occur while the 
subject is already onsite for the Test of Cure or Early Termination Visit from the 
Randomization Period), study drug (miconazole oil) will be weighed and dispensed to the 
subject along with a subject diary. Subjects or their caregivers will administer the first dose of 
miconazole oil at the site. AEs and concomitant medications will then be assessed. Subjects 
will then continue to administer miconazole oil and to complete the subject diary twice per day 
for a total of 14 days, following the same instructions as provided at the Screening/Baseline 
Visit on Day 1. 
Subjects will return to the clinic on Day OLE15 for the End of Treatment Visit, at which time a 
clinical evaluation of the signs and symptoms of otomycosis will be performed, as well as an 
assessment of AEs and concomitant medications. A urine pregnancy test will be performed in 
women of childbearing potential. The subject will return all unused miconazole oil along with 
the completed subject diary.  
Data for Enrollment A will be unblinded after all subjects planned for Enrollment A have 
completed both the Randomization Period and the Optional Open-label Extension, so that 
analyses from Enrollment A can be conducted even if Enrollment B is still ongoing (i.e., before 
the conclusion of Enrollment B). 
Enrollment B 
Enrollment B may be initiated while Enrollment A is still actively enrolling subjects. An 
estimated 170 male or female subjects will receive study drug (miconazole oil) in Enrollment B, 
although this number may be higher or lower depending on the total number of subjects 
needed to achieve at least 300 subjects who are exposed to miconazole oil for 14 days in the 
study overall who are evaluable for safety.  
At Screening/Baseline (Day B1), potentially eligible subjects will provide informed consent, and 
subjects will undergo screening evaluations to include a physical examination and an 
evaluation of medical history. Urine will be obtained for pregnancy screening in female 
subjects of childbearing potential. Prior and concomitant medications will be reported. Subjects 
who meet all eligibility criteria will be entered into the study. Study drug will be weighed and 
dispensed to the subject along with a subject diary. The subject will then begin treatment with 
miconazole oil. In subjects who do not have otomycosis, treatment will be in the left ear if both 
ears are otherwise eligible; if only one ear is eligible, treatment will be in that ear. In subjects 
who have otomycosis (i.e., any signs and/or symptoms consistent with a clinical diagnosis of 
otomycosis in the judgment of the investigator), treatment will preferably be in the ear(s) with 
otomycosis, provided the ear(s) meet all eligibility criteria. If both ears are judged by the 
investigator to have otomycosis and both meet all eligibility criteria, both ears may be treated. 
The subject or caregiver will instill the first dose of miconazole oil at the site, under the

supervision of the investigator or site personnel. AEs will then be assessed. The subject will 
then leave the clinic and continue to administer miconazole oil and to complete the subject 
diary twice per day, following the same instructions for miconazole oil administration as in 
Enrollment A. 
Subjects will return to the clinic on Day B15 for the End of Treatment Visit, at which time AEs 
and concomitant medications will be assessed. Subjects will return all unused miconazole oil 
along with the completed subject diary. A urine pregnancy test will be performed in women of 
childbearing potential. 
Timing of Subject Recruitment Into Enrollment A and Enrollment B 
The study will start with Enrollment A, which will continue until the sponsor determines that a 
sufficient number of subjects (see Sample Size below) has been recruited to conduct the 
planned analyses for Enrollment A, at which time the sponsor (or designee) will notify all study 
sites to terminate further enrollment into the Enrollment A portion of the study. 
Recruitment of subjects into Enrollment B will begin when the sponsor (or designee) notifies 
sites to begin recruiting subjects into Enrollment B, and will end when the sponsor (or 
designee) notifies study sites to pause or permanently terminate recruitment of subjects into 
Enrollment B. Enrollment B may occur over one or multiple time periods, each of which will 
begin and then pause (or permanently end) upon sponsor (or designee) notification to the 
study sites. The purpose of this mechanism is to allow concurrent enrollment of Enrollment A 
and Enrollment B at times (such as during the wintertime) when recruitment into Enrollment A 
is likely to be diminished due to a lower expected incidence of otomycosis, while also allowing 
the sponsor the flexibility to pause or permanently terminate recruitment into Enrollment B for 
reasons including (but not limited to) time periods during which a higher incidence of 
otomycosis is expected (at which times the sponsor may wish for the focus of the study to be 
on recruitment of subjects into Enrollment A), or evaluation by the sponsor of the number of 
subjects still needed for Enrollment B (see Sample Size below).  
At times when Enrollment A and Enrollment B are concurrently ongoing, if a subject is found to 
be eligible for both Enrollment A and Enrollment B, the subject should be enrolled into 
Enrollment A whenever possible.

Test Product, Dose, and Mode of Administration: 
Miconazole oil 
Active ingredient: 2% miconazole 
Other ingredients: refined peanut oil, mineral oil, oleth-2, and isopropyl myristate 
Mode of administration: subjects will be seated and then instructed to tilt their heads so that 
the affected ear is facing up. The subject or caregiver will then gently pull the ear lobe 
backward and upward and apply 5 drops of miconazole oil into the ear. The subject will be 
instructed to keep the head tilted with the ear facing up for approximately 3 to 5 minutes to 
allow the miconazole oil to penetrate lower into the ear canal. If both ears are being treated, 
the process will then be repeated for the other ear after a 5-minute wait.

Endpoints: 
Primary Efficacy Endpoint 
• 
Percentage of subjects with “therapeutic cure,” defined as “mycological cure” plus 
“clinical cure” at the Test of Cure Visit. Mycological cure is defined as a negative 
mycological culture, and clinical cure is defined as the absence of all otomycosis signs 
and symptoms according to the scales for each individual sign or symptom. 
Secondary Efficacy Endpoints 
• 
Percentage of subjects with mycological cure at the Test of Cure Visit. 
• 
Percentage of subjects with clinical cure at the Test of Cure Visit. 
Tertiary Efficacy Endpoints 
• 
Percentage of subjects with “modified therapeutic cure” at the Test of Cure Visit, 
defined as mycological cure plus a score of 0 for the clinical sign of fungal elements 
plus a score of 0 or 1 for each of the clinical signs and symptoms of pruritus, debris, 
and aural fullness. 
• 
Percentage of subjects with “therapeutic improvement” at the Test of Cure Visit, 
defined as mycological cure plus a score of 0 or 1 for each of the clinical signs and 
symptoms of fungal elements, pruritus, debris, and aural fullness. 
Safety Endpoint 
• 
Percentage of subjects with treatment-emergent adverse events (TEAEs). 
Statistical Analyses: 
Descriptive statistics will be presented for the percentages of subjects by treatment group with 
therapeutic cure, mycological cure, and clinical cure in the study ear at each evaluation. 
Descriptive statistics will also be presented for the percentages of subjects by treatment group 
with success at each secondary and tertiary endpoint, and for each sign or symptom of 
otomycosis in the study ear at each evaluation. Descriptive statistics will include the number 
and percentage of subjects in each category. 
In Enrollment A in cases of bilateral otomycosis, the ear with the worse infection at 
Screening/Baseline, as assessed by the investigator by taking into account both clinical signs 
and symptoms and fungal culture results, will be used as the study ear for efficacy analyses. If 
both ears are determined by the investigator to have the same degree of infection at 
Screening/Baseline, the left ear will be used as the study ear for the purposes of efficacy 
analyses. 
For the primary efficacy endpoint, percentages of subjects with therapeutic cure at the Test of 
Cure Visit will be compared using a chi-square test with a 2-sided significance level of 0.05. 
Comparisons will be conducted in a similar manner between the miconazole oil and vehicle oil

groups for the secondary endpoints of clinical cure and mycological cure. Missing data will be 
imputed as treatment failures for the primary and secondary efficacy analyses; missing data 
otherwise will not be imputed. 
The primary population for efficacy analyses will be the MITT population, defined as all 
subjects who were randomized with a positive fungal culture at Screening/Baseline. 
Two safety populations will be used for safety analyses. The first will be the Randomization 
Period safety population, defined as all subjects who received at least one dose of study drug 
and had at least one post-Baseline safety assessment during the Randomization Period; this 
population will be used for safety data for the Randomization Period. The second will be the 
Open Label safety population, defined as all subjects who received at least one dose of 
miconazole oil and had at least one post-Baseline safety assessment during the Optional 
Open-label Extension or Enrollment B; this population will be used for safety data for the 
Optional Open-label Extension and Enrollment B. 
All AEs occurring during the study will be recorded and classified using terminology from the 
Medical Dictionary for Regulatory Activities (MedDRA). All reported TEAEs, defined as any AE 
with an onset on or after the date of first study drug application, will be summarized. 
Summaries will provide the number of subjects reporting TEAEs, system organ class, 
preferred term, severity, and relationship to study drug. When summarizing TEAEs by severity 
or relationship to study drug, each subject will be counted only once within a system organ 
class or a preferred term using the event with the greatest severity or causality, respectively, 
within each category. All reported serious AEs (SAEs) will be summarized by the number of 
subjects reporting the event, system organ class, preferred term, severity, and relationship to 
study drug. Descriptive statistics will be presented for all safety data. 
Sample Size: 
For the Randomization Period of Enrollment A, approximately 128 subjects (~64 in each 
group) are required to provide 80% power, using a chi-square test with a 2-sided significance 
level of 0.05, assuming a response rate for the primary efficacy endpoint of 25.0% in the 
miconazole oil group and 7.1% in the vehicle oil group.  
The sample size of 220 subjects for Enrollment A assumes that ~58% of subjects enrolled into 
Enrollment A will have a positive fungal culture at Screening/Baseline and will therefore be 
included in the MITT population. This number may be higher or lower depending on the 
percentage of subjects eligible to be included in the MITT population. 
The overall study sample size of ~390 subjects is the total number of study subjects estimated 
to achieve at least 300 subjects exposed to miconazole oil for 14 days who are evaluable for 
safety. A higher or lower number of total subjects may be enrolled in order to achieve the 
required total numbers of subjects for each of Enrollment A and Enrollment B.

INTRODUCTION 
1.1 
Background 
Miconazole is an imidazole antifungal agent that has been available by prescription and over the 
counter (OTC), in different formulations, for many years. It is commonly used for different types 
of fungal skin infections, such as Candida, ringworm, jock itch, athlete’s foot, nail fungus, 
vaginal yeast infections, and oropharyngeal candidiasis. Formulations containing up to 4% 
miconazole nitrate have been approved for OTC use as topical antifungal agents in cream, 
ointment, powder, or gel dosage forms. The 2% formulation is commonly used for 
dermatophytic infections. 
While antifungal agents including miconazole are used in practice for the treatment of fungal 
otitis externa (also called otomycosis), there are currently no treatments approved by the United 
States (US) Food and Drug Administration (FDA) for this indication in humans. Miconazole is 
currently FDA-approved as a component of two veterinary combination products (Surolan and 
Easotic) administered otically to dogs for the treatment of canine otitis externa caused by 
susceptible strains of yeast and bacteria. Each veterinary product contains miconazole in 
combination with an antibacterial agent and a corticosteroid. The concentration of miconazole 
present in Surolan (23 mg/mL miconazole nitrate) is similar to the 2% concentration of 
miconazole planned for use in humans in this study. The concentration of miconazole present in 
Easotic is 15.1 mg/mL miconazole nitrate, which equates to approximately 1.5% miconazole. 
While the causative organism of canine otitis externa, Malassezia pachydermatis, is not typically 
associated with human otomycosis in the US, it is expected that human otomycosis, which is 
most commonly associated with organisms from the Candida and Aspergillus genera, would 
respond to concentrations of miconazole similar to those used in dogs. 
The mechanisms of action of miconazole when used topically for the treatment of fungal 
infections involve its actions against the fungal organisms, rather than their human host. 
Miconazole targets the cytochrome P450-dependent enzyme 14-α-sterol demethylase, an enzyme 
that is also involved in mammalian cholesterol synthesis, resulting in inhibition of ergosterol 
biosynthesis in the cell membrane. Because ergosterol is an important component of the cell 
membrane, inhibition of its synthesis inhibits fungal cell growth [Vandenbosch 2012]. In 
addition to its activity toward the enzyme 14-α-sterol demethylase, miconazole also leads to 
increased reactive oxygen species in fungal organisms, which appears to result in fungicidal 
activity [Vandenbosch 2010; Musaji 2010]. 
The mechanisms of action of miconazole against fungi in general appear to be applicable to 
fungi associated with otomycosis. Data from a recently-completed Phase 2 study of the 
investigational product (2% miconazole oil; Hill Dermaceuticals, Inc. Study HD-MCZ-PHII-
DRF062016) demonstrated 25.0% of subjects with therapeutic cure, defined as a negative fungal 
culture plus the absence of each of the otomycosis signs and symptoms of pruritus, debris, fungal 
elements, and pain, compared with 7.1% of subjects treated with control product (vehicle oil), at 
the final test of cure study visit, following a 14-day treatment regimen. The percentage of 
subjects with therapeutic cure following a 7-day treatment regimen was 8.3%, supporting the 
14-day treatment duration for miconazole.

Clinical studies of 2% miconazole conducted outside of the United States also suggest the 
efficacy of miconazole in the treatment of human otomycosis [Kiakojuri 2007; Vennewald 2010; 
Navaneethan 2015]. In vitro studies of miconazole have also demonstrated activity of 
miconazole against some clinical isolates of fungi associated with human otomycosis in the US 
[Bassiouny 1986; Stern 1988].  
Adverse event (AE) data from the recently-completed Phase 2 study of the investigational study 
support the acceptable safety of miconazole oil and generally demonstrated a lower percentage 
of patients with treatment-emergent AEs (TEAEs) in each of the miconazole oil groups (which 
were treated for either 7 or 14 days) compared with the vehicle oil group (which was treated for 
14 days). The most frequently reported TEAEs in the 14-day miconazole oil group in the Phase 2 
study were application site pruritus, application site pain, and ear infection fungal (Table 1). In 
each case except for ear infection fungal, a higher percentage of subjects in the 14-day vehicle 
oil group compared with the 14-day miconazole oil group reported the TEAE. Similar results 
were observed for the 7-day miconazole oil group, although a higher percentage of subjects in 
the 7-day miconazole oil group had the TEAE of application site infection compared with the 14-
day miconazole oil and 14-day vehicle oil groups.

No serious AEs (SAEs) were reported in the Phase 2 study. AEs leading to discontinuation in the 
Phase 2 study were observed in a higher percentage of subjects in the 14-day vehicle oil group 
compared with either the 14-day miconazole oil or 7-day miconazole oil group, providing further 
evidence of an acceptable safety profile for miconazole oil (Table 2).

Study Purpose 
The purpose of this study is to gather confirmatory data on the efficacy and safety of 2% 
miconazole oil after topical otic administration in subjects with otomycosis. During the 
Randomization Period of the Enrollment A portion of the study, a 14-day regimen of twice-daily 
administration of 2% miconazole oil will be compared with the same treatment regimen using 
the product vehicle. During the Optional Open-label Extension of the Enrollment A portion and 
the Enrollment B portion of the study, a 14-day regimen of twice-daily administration of 2% 
miconazole oil will be administered in an open-label fashion in order to gather safety information 
in additional subjects. 
1.3 
Inclusion of Subjects with Peanut Allergy 
Miconazole oil contains refined peanut oil. Inclusion in this study of subjects with peanut allergy 
is justified by studies and publications documenting safe use of the refined peanut oil, as well as 
products containing the refined peanut oil (such as DermOtic, which is the same product as the 
Derma-Smoothe/FS for which two safety studies were performed in subjects with known 
hypersensitivity to peanuts) [Yunginger 2001; Paller 2003]. Reports also exist of subjects with 
known peanut allergy who have continued to safely use products such as Derma-Smoothe/FS 
even after an anaphylactic reaction to peanuts [Paller 2003]. The refined peanut oil used in the 
Derma-Smoothe/FS, DermOtic, and miconazole oil products has been treated to remove the 
peanut proteins which are generally responsible for allergic reactions to peanuts. Thus, the 
inclusion of subjects with peanut allergy in this study is not expected to pose an excessive risk to 
these subjects.

STUDY DESIGN 
This study will be conducted in 2 portions (see also Figure 1 for a schematic diagram of the 
study design): 
1. Enrollment A, which will consist of 2 treatment periods as follows and will be conducted in 
subjects with otomycosis: 
a. A randomized, double-blind, parallel-group treatment period. This treatment period will 
be referred to as the "Randomization Period" and will be followed by: 
b. An optional, open-label treatment period with miconazole oil. This treatment period will 
be referred to as the "Optional Open-label Extension." 
2. Enrollment B, which will consist of open-label treatment with miconazole oil in subjects who 
will not be required to have signs and symptoms of otomycosis.

Enrollment A 
The study will start with Enrollment A, in which an estimated 220 male or female subjects with 
otomycosis will receive study drug, although this number may be higher or lower depending on 
the percentage of subjects eligible to be included in the modified intent-to-treat (MITT) 
population (see Section 10.4.2). Subjects will be randomly assigned in a 1:1 ratio to receive 
miconazole oil or vehicle, for 14 days. The study drug will be administered as 5 drops per ear at 
~30 mg per drop instilled into the external ear canal of the ear(s) affected by otomycosis.

3.1.1 
Randomization Period 
During the Randomization Period, both the subject and the investigator and study staff will be 
blinded as to the contents of the study drug.  
At Screening/Baseline (Day 1), potentially eligible subjects will provide informed consent, and 
subjects will undergo screening evaluations to include a physical examination, an assessment of 
the signs and symptoms of otomycosis (pruritus, debris, visual examination for presence of 
fungal elements, and aural fullness), and an evaluation of medical history. Urine will be obtained 
for pregnancy screening in female subjects of childbearing potential. Prior and concomitant 
medications will be reported. Subjects with positive signs and symptoms of otomycosis and who 
meet all other eligibility criteria will be entered into the study. A fungal culture of the affected 
ear(s) will be taken, then debris will be cleaned from the affected ear(s) following the site’s 
normal procedures. The subject will be randomized, and study drug will be weighed and 
dispensed to the subject along with a subject diary. The subject will then begin treatment with 
study drug. The subject or caregiver will instill the first dose of study drug at the site, under the 
supervision of the investigator or site personnel. Adverse events (AEs) will then be assessed. The 
subject will then leave the clinic and continue to administer the study drug and to complete the 
subject diary twice per day as instructed. Subjects will be instructed to avoid getting water in the 
ear, to consider drying excessive water in the ear by using a blow dryer, and to place a Vaseline-
impregnated cotton ball over the affected ear(s) to help keep water out of the ear while bathing or 
showering. 
Subjects will return to the clinic on Day 8 for the On Treatment Visit, at which time a clinical 
evaluation of the signs and symptoms of otomycosis, a cleaning of the affected ear(s) (following 
the site’s normal procedures), a review of the subject diary, and an assessment of AEs and 
concomitant medications will be performed. Subjects will continue to administer the study drug 
and to complete the subject diary twice per day, up through Day 14, following the same 
instructions as provided at the Screening/Baseline Visit on Day 1. 
Subjects will return to the clinic on Day 15 for the End of Treatment Visit, at which time a 
clinical evaluation of the signs and symptoms of otomycosis and a fungal culture of the affected 
ear(s) will be performed; however, a fungal culture will not be required at this visit for subjects 
known to have a negative fungal culture at Screening/Baseline, as assessed after at least 14 days 
of incubation by the clinical laboratory performing the fungal culture. AEs and concomitant 
medications will also be assessed, and the subject will return all unused study drug along with 
the completed subject diary.  
Subjects will return to the clinic on Day 22 for the Test of Cure Visit, at which time an 
assessment of clinical signs and symptoms of otomycosis and a fungal culture of the affected 
ear(s) will be performed; however, a fungal culture will not be required at this visit for subjects 
known to have a negative fungal culture at Screening/Baseline, as assessed after at least 14 days 
of incubation by the clinical laboratory performing the fungal culture. AEs and concomitant 
medications will also be assessed. A urine pregnancy test will be performed in women of 
childbearing potential.

Efficacy assessments will include fungal culture of the affected ear(s), and assessments of 
clinical signs and symptoms of otomycosis. In cases of bilateral otomycosis, both ears will be 
treated and evaluated by the investigator, but only 1 ear will be used as the study ear for efficacy 
analyses, the designation of which will be performed at the end of the study in accordance with 
the following. If only 1 ear has a positive fungal culture at Screening/Baseline, that ear will be 
used as the study ear for efficacy analyses. If both ears have a positive fungal culture at 
Screening/Baseline, the ear with the worse infection at Screening/Baseline, as assessed by the 
investigator by taking into account the clinical signs and symptoms of otomycosis, will be used 
as the study ear for efficacy analyses. If both ears have a positive fungal culture and are 
determined by the investigator to have the same degree of infection at Screening/Baseline, the 
left ear will be used as the study ear for the purposes of efficacy analyses. 
Safety assessments will include AEs. 
3.1.2 
Optional Open-label Extension 
Subjects who either complete the Randomization Period of the study (up through the Test of 
Cure Visit), or who are prematurely discontinued from study treatment during the 
Randomization Period due to worsening of signs and/or symptoms of otomycosis in the 
judgment of the investigator, will be offered the opportunity to participate in an optional open-
label extension, if they have a visual presence of fungal elements in at least one ear treated 
during the Randomization Period. Only the ear(s) that were treated in the Randomization Period 
will be potentially eligible for treatment during the Optional Open-label Extension. 
All subjects in the Optional Open-label Extension will receive miconazole oil for 14 days. No 
unblinding of the subject’s treatment in the Randomization Period will occur at this time. 
Before a subject enters the Optional Open-label Extension, all procedures for the Test of Cure 
Visit will be completed for that subject; however, a fungal culture will not be required at this 
visit for subjects known to have a negative fungal culture at Screening/Baseline, as assessed after 
at least 14 days of incubation by the clinical laboratory performing the fungal culture.  
At the first visit of the Optional Open-label Extension (Day OLE1, which will occur while the 
subject is already onsite for the Test of Cure or Early Termination Visit from the Randomization 
Period), study drug (miconazole oil) will be weighed and dispensed to the subject along with a 
subject diary. Subjects or their caregivers will administer the first dose of miconazole oil at the 
site. AEs and concomitant medications will then be assessed. Subjects will then continue to 
administer miconazole oil and to complete the subject diary twice per day for a total of 14 days, 
following the same instructions as provided at the Screening/Baseline Visit on Day 1. 
Subjects will return to the clinic on Day OLE15 for the End of Treatment Visit, at which time a 
clinical evaluation of the signs and symptoms of otomycosis will be performed, as well as an 
assessment of AEs and concomitant medications. A urine pregnancy test will be performed in 
women of childbearing potential. The subject will return all unused miconazole oil along with 
the completed subject diary.

Page 24 of 88 
The purpose of the Optional Open-label Extension is safety and to provide supportive evidence 
of efficacy. Efficacy assessments will include assessments of clinical signs and symptoms of 
otomycosis. Safety assessments will include AEs. 
3.1.3 
Timing of Analysis for Enrollment A 
Data for Enrollment A will be unblinded after all subjects planned for Enrollment A have 
completed both the Randomization Period and the Optional Open-label Extension, so that 
analyses from Enrollment A can be conducted even if Enrollment B is still ongoing (i.e., before 
the conclusion of Enrollment B). 
3.2 
Enrollment B 
Enrollment B may be initiated while Enrollment A is still actively enrolling subjects. An 
estimated 170 male or female subjects will receive study drug (miconazole oil) in Enrollment B, 
although this number may be higher or lower depending on the total number of subjects needed 
to achieve at least 300 subjects who are exposed to miconazole oil for 14 days in the study 
overall who are evaluable for safety.  
At Screening/Baseline (Day B1), potentially eligible subjects will provide informed consent, and 
subjects will undergo screening evaluations to include a physical examination and an evaluation 
of medical history. Urine will be obtained for pregnancy screening in female subjects of 
childbearing potential. Prior and concomitant medications will be reported. Subjects who meet 
all eligibility criteria will be entered into the study. Study drug will be weighed and dispensed to 
the subject along with a subject diary. The subject will then begin treatment with miconazole oil. 
In subjects who do not have otomycosis, treatment will be in the left ear if both ears are 
otherwise eligible; if only one ear is eligible, treatment will be in that ear. In subjects who have 
otomycosis (i.e., any signs and/or symptoms consistent with a clinical diagnosis of otomycosis in 
the judgment of the investigator), treatment will preferably be in the ear(s) with otomycosis, 
provided the ear(s) meet all eligibility criteria. If both ears are judged by the investigator to have 
otomycosis and both meet all eligibility criteria, both ears may be treated. The subject or 
caregiver will instill the first dose of miconazole oil at the site, under the supervision of the 
investigator or site personnel. AEs will then be assessed. The subject will then leave the clinic 
and continue to administer miconazole oil and to complete the subject diary twice per day, 
following the same instructions for miconazole oil administration as in Enrollment A. 
Subjects will return to the clinic on Day B15 for the End of Treatment Visit, at which time AEs 
and concomitant medications will be assessed. Subjects will return all unused miconazole oil 
along with the completed subject diary. A urine pregnancy test will be performed in women of 
childbearing potential. 
Safety assessments will include AEs. 
3.3 
Timing of Subject Recruitment Into Enrollment A and Enrollment B 
The study will start with Enrollment A, which will continue until the sponsor determines that a 
sufficient number of subjects (see Section 3.4) has been recruited to conduct the planned 

Hill Dermaceuticals, Inc. 
 
Protocol MZ-0120-ESP3-052 
 
 
14 Sep 2020 / Version 4 
Page 25 of 88 
analyses for Enrollment A, at which time the sponsor (or designee) will notify all study sites to 
terminate further enrollment into the Enrollment A portion of the study. 
Recruitment of subjects into Enrollment B will begin when the sponsor (or designee) notifies 
sites to begin recruiting subjects into Enrollment B, and will end when the sponsor (or designee) 
notifies study sites to pause or permanently terminate recruitment of subjects into Enrollment B. 
Enrollment B may occur over one or multiple time periods, each of which will begin and then 
pause (or permanently end) upon sponsor (or designee) notification to the study sites. The 
purpose of this mechanism is to allow concurrent enrollment of Enrollment A and Enrollment B 
at times (such as during the wintertime) when recruitment into Enrollment A is likely to be 
diminished due to a lower expected incidence of otomycosis, while also allowing the sponsor the 
flexibility to pause or permanently terminate recruitment into Enrollment B for reasons including 
(but not limited to) time periods during which a higher incidence of otomycosis is expected (at 
which times the sponsor may wish for the focus of the study to be on recruitment of subjects into 
Enrollment A), or evaluation by the sponsor of the number of subjects still needed for 
Enrollment B (see Section 3.4).  
At times when Enrollment A and Enrollment B are concurrently ongoing, if a subject is found to 
be eligible for both Enrollment A and Enrollment B, the subject should be enrolled into 
Enrollment A whenever possible. 
3.4 
Number of Subjects 
Approximately 390 total subjects are estimated to be enrolled into the study (~220 subjects 
estimated for Enrollment A and ~170 subjects estimated for Enrollment B) as described in 
Section 3.4.1 for Enrollment A and in Section 3.4.2 for Enrollment B. 
3.4.1 
Enrollment A 
An estimated 220 eligible subjects are planned to be enrolled in Enrollment A in order to achieve 
at least 128 evaluable subjects (i.e., included in the MITT population, defined as those who were 
randomized with a positive fungal culture at Screening/Baseline). The number of subjects who 
are enrolled may be higher or lower than 220 depending on the percentage of subjects eligible to 
be included in the MITT population; enrollment in Enrollment A will continue until the required 
numbers of subjects have been achieved. 
3.4.2 
Enrollment B 
An estimated 170 eligible subjects are planned to be enrolled in order to achieve at least 300 total 
subjects in the study (including both Enrollment A and Enrollment B) who are exposed to 
miconazole oil for 14 days who are evaluable for safety. This number has been estimated on the 
basis of the following assumptions: 
• A total of 220 subjects will be enrolled into the Randomization Period of Enrollment A, with 
110 subjects exposed to active treatment with miconazole oil (on the basis of the 1:1 
randomization for the Randomization Period), and 110 subjects exposed to the vehicle 
treatment: 

Hill Dermaceuticals, Inc. 
 
Protocol MZ-0120-ESP3-052 
 
 
14 Sep 2020 / Version 4 
Page 26 of 88 
• Of the 110 subjects exposed to active treatment (miconazole oil) in the Randomization 
Period, ~90% (100 subjects) will complete the full 14 days of treatment, with the 
remaining ~10% (10 subjects) completing less than the 14-day treatment course 
• Of the 110 subjects exposed to vehicle treatment in the Randomization Period, ~50% (55 
subjects) will opt to participate in the Optional Open-label Extension of Enrollment A, 
with the other ~50% (55 subjects) concluding participation in the study 
• Of the 55 subjects exposed to miconazole oil treatment in the Optional Open-label Extension, 
~90% (50 subjects) will complete the full 14 days of treatment, with the remaining ~10% (5 
subjects) completing less than the 14-day treatment course 
• On the basis of these assumptions, ~150 subjects will have been exposed to miconazole oil 
for the full 14-day treatment during Enrollment A (100 subjects during the Randomization 
Period and 50 subjects during the Optional Open-label Extension), and an additional ~150 
subjects exposed to miconazole oil for the full 14-day treatment will be needed to achieve the 
≥300 total subjects required to be exposed to miconazole oil for the full 14-day treatment 
• Assuming ~90% of subjects enrolled into Enrollment B complete the full 14 days of open-
label treatment with miconazole oil, ~170 subjects will be required to be enrolled in 
Enrollment B in order to achieve ~150 subjects who complete the full 14-day treatment with 
miconazole oil 
• Therefore, ~150 subjects from Enrollment A and ~150 subjects from Enrollment B are 
estimated to be needed for at least 300 total subjects in the study who are exposed to 
miconazole oil for a full 14 days. 
The actual number of subjects enrolled into Enrollment B may therefore be higher or lower than 
170 depending on the accuracy of the assumptions as stated above, including the number of 
subjects who have completed a full 14 days of treatment with miconazole oil in Enrollment A as 
well as in Enrollment B. Enrollment will continue into Enrollment B until the required number of 
subjects exposed to miconazole oil for 14 days and evaluable for safety has been achieved.  
3.5 
Investigators 
The study will be conducted at up to 20 investigative sites located in the US. 
The study will be conducted by investigators who are determined by the sponsor to be suitably 
qualified by training and experience to conduct this study in compliance with all applicable GCP 
and FDA federal regulations or local regulations. Sub-investigators will be identified on the 
Form FDA 1572.

Page 27 of 88 
During Enrollment A, the study duration for a subject who participates only in the 
Randomization Period of the study will be up to 31 days, which includes up to 1 day for 
screening (if screening procedures need to be initiated the day before treatment), 14 days for 
treatment, and 8 days of follow-up, including the visit window of up to 8 additional days after 
the scheduled day to complete the final Test of Cure Visit. 
The study duration for each subject who participates in both the Randomization Period and 
Optional Open-label Extension will be up to approximately 48 days, which includes up to 31 
days for the Randomization Period followed by up to 17 days for the Optional Open-label 
Extension (which includes a visit window of up to 3 additional days after the 14-day treatment to 
complete the final study visit). This study duration takes into account that the Day OLE1 
procedures will occur while the subject is already onsite for the Test of Cure or Early 
Termination Visit for the Randomization Period.

Screening/Baseline and must agree to use an effective method of contraception (as defined in 
Section 8.5) from Screening/Baseline up through the Test of Cure Visit (see Section 6). 
Females of childbearing potential include any female who has experienced menarche and 
who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation 
or bilateral oophorectomy) or is not postmenopausal (defined as amenorrhea >12 consecutive 
months). Females who are using oral, implanted, or injectable contraceptive hormones, an 
intrauterine device (IUD), barrier methods (diaphragm, condoms, spermicide) to prevent 
pregnancy, practicing abstinence or where partner is sterile (e.g., vasectomy), should be 
considered to be of childbearing potential 
5. Subjects and/or their caregivers (as appropriate for the age of the subject) must have full 
legal capacity to volunteer 
6. Subjects and/or their caregivers must have completed an appropriately administered 
institutional review board (IRB)-approved informed consent and assent (as applicable) prior 
to any study related procedures 
7. Subjects and their caregivers (as applicable) must agree to comply with all requirements of 
the protocol 
8. For subjects with only one ear meeting all study eligibility criteria, the subject will be eligible 
for the study, and the ear meeting all eligibility criteria will be treated with study drug and 
considered to be the study ear for the purposes of study evaluations. In case of bilateral 
otomycosis in which both ears meet all study eligibility criteria, the subject will be eligible 
for the study, both ears may be treated with study drug, and the worse ear will be considered 
to be the study ear for the purposes of study evaluations. If both ears meet study eligibility 
criteria and are determined by the investigator to have the same degree of infection at 
Screening/Baseline, the left ear will be considered to be the study ear for the purposes of 
study evaluations. 
4.1.2 
Exclusion Criteria 
Subjects meeting any of the following criteria will not be eligible for Enrollment A: 
1. Any other dermatoses or conditions of the ear that may interfere with the evaluation of 
otomycosis or with safety evaluations, including concomitant otic infections (including 
bacterial infection) other than otomycosis that require antimicrobial treatment, disease that 
has spread beyond the external ear(s), or pre-existing skin atrophy of the affected ear(s) that 
will be treated with study drug 
2. Tympanostomy tube or perforated tympanic membrane in the ear(s) that will be treated with 
study drug 
3. History of prior surgery directly affecting and compromising the external auditory canal 
and/or tympanic membrane of the ear(s) that will be treated with study drug, except for prior

4.3 
Subject Discontinuation 
A subject MAY be withdrawn from the study (at the discretion of the investigator, sponsor, 
and/or IRB) prior to study completion for any of the following reasons, including, but not limited 
to: 
• A serious adverse event (SAE) occurring during the course of the study which precludes 
continued follow-up 
• Intercurrent illness which may, in the investigator’s opinion, significantly affect study 
assessments 
• Failure to follow required study procedures 
• For subjects participating in Enrollment A, a negative fungal culture at Screening/Baseline 
(as assessed after at least 14 days of incubation by the clinical laboratory performing the 
fungal cultures) 
A subject MUST be discontinued prior to the final study visit for any of the following reasons: 
• Whenever the subject decides it is in his/her best interest to withdraw 
• Whenever the investigator decides it is in the subject’s best interest to be withdrawn 
Prior to discontinuing a subject, every effort should be made to contact the subject, schedule a 
final study visit, and obtain as much follow-up data as possible. If possible, the assessment 
schedule for the Test of Cure Visit (Randomization Period) or the End of Treatment Visit 
(Optional Open-label Extension or Enrollment B) should be performed, and an effort should be 
made to collect all study drug. A fungal culture is not required for subjects who are prematurely 
discontinued from the study. 
For Enrollment A, due to the time required to obtain fungal culture results from 
Screening/Baseline, subjects will be enrolled into the study based on a clinical diagnosis of 
otomycosis (including the visible presence of fungal elements at Screening/Baseline), without a 
requirement for a positive fungal culture. Subjects who end up with a negative 
Screening/Baseline fungal culture are not required to be discontinued from the study, but these 
subjects will not be included in the primary efficacy analysis. Because the sponsor’s goal is to 
have at least 128 subjects in the MITT population (see Section 10.4.2), the total number of 
subjects enrolled into Enrollment A may be higher or lower than 220, depending on the 
percentage of subjects who are eligible to be included in the MITT population. 
Subject discontinuations will be documented clearly on the applicable electronic case report form 
(eCRF). Subjects who discontinue from the study will not be replaced, but additional subjects 
may be enrolled and randomized into Enrollment A if it appears that the estimated number of 
subjects for Enrollment A (approximately 220) is insufficient to meet the sponsor’s goal of 
having at least 128 subjects in the MITT population. After completion of Enrollment A, 
additional subjects (i.e., exceeding the 390 subjects total for the study) may be enrolled into 
Enrollment B if it appears that the estimated total number of study subjects is insufficient to 
achieve at least 300 subjects who have been exposed to miconazole oil for 14 days who are 
evaluable for safety.

Subjects Lost to Follow-up 
An effort must be made to contact subjects who do not return for scheduled visits, to schedule 
the visit and/or obtain as much follow-up data as possible. At least three telephone calls and one 
certified letter must be placed to the subject after the first missed visit, to attempt to get the 
subject to complete the visit and to gather as much follow-up data as possible, before a subject 
may be considered lost to follow-up and discontinued from the study. Subjects who miss a visit 
may still be scheduled for a subsequent visit. 
All follow-up attempts will be documented and kept with the subject’s source documentation, 
and the applicable eCRFs will be completed. The date a subject will be considered lost to follow-
up will be the date of the last non-missing visit. 
5 
CONCOMITANT THERAPIES 
All concomitant therapies must be recorded on the eCRF. 
Every effort should be made to keep concomitant therapy and dosing constant during the study. 
Any changes in concomitant therapies during the study must be recorded on the eCRF at each 
visit. The reason for any change in concomitant therapies should be reported as, or in 
conjunction with, an AE except as noted below:  
• Prophylactic therapies, such as vaccines or prophylactic analgesics, must be recorded on the 
eCRF but should not be reported as AEs.  
• Changes in therapy for pre-existing conditions that are not related to a worsening of the 
condition must be reported on the eCRF but should not be reported as AEs. The condition 
must be reported on the eCRF as part of the subject’s medical history.  
5.1 
Enrollment A 
In addition to all concomitant therapies, all therapies within 3 months prior to Day 1 must also be 
recorded on the eCRF. 
5.1.1 
Permitted Medications 
Therapies (medication and non-medication therapies) not restricted by the protocol may be used 
during the study for the treatment or prevention of disease or to maintain good health. Vitamins 
and mineral supplements are permitted at dosages considered by the investigator as reasonable 
for maintaining good health. Non-prohibited chronic therapies being used at Screening/Baseline 
may be continued. 
Oral analgesic medications such as non-steroidal anti-inflammatory drugs (NSAIDs) or 
acetaminophen are permitted. Such medications may be helpful for the management of pain 
caused by otomycosis and/or study procedures such as ear cleaning and administration of study 
drug.

5.1.2 
Prohibited Medications 
Other than the study drug, no other topical medications (including but not limited to antibiotics, 
alcohol, boric acid, peroxide, and/or corticosteroids) are allowed to be used in the ear(s) being 
treated with study drug. Other prohibited treatments include systemic antifungal therapy, 
warfarin, immunosuppressive or immune-stimulating drugs, and systemic steroids. A subject 
who discontinues study drug during the Randomization Period and who subsequently uses a 
topical corticosteroid (e.g., to treat an AE such as itching) in the ear(s) that were treated with 
study drug during the Randomization Period will be eligible for the Optional Open-label 
Extension if the topical corticosteroid is discontinued in the ear(s) that will be treated with study 
drug before the start of study drug in the Optional Open-label Extension, and as long as the 
subject meets all other eligibility criteria for the Optional Open-label Extension. 
5.2 
Enrollment B 
In addition to all concomitant therapies, all therapies within 28 days prior to Day B1 must also be 
recorded on the eCRF. 
5.2.1 
Permitted Medications 
Therapies (medication and non-medication therapies) not restricted by the protocol may be used 
during the study for the treatment or prevention of disease or to maintain good health. Vitamins 
and mineral supplements are permitted at dosages considered by the investigator as reasonable 
for maintaining good health. Non-prohibited chronic therapies being used at Screening/Baseline 
may be continued. 
Oral analgesic medications such as NSAIDs or acetaminophen are permitted.

6.3 
Screen Failures 
Subjects in both portions of the study who sign informed consent and are then found not to meet 
all eligibility criteria will be considered screen failures. 
6.4 
Unscheduled Study Visits 
Additional visits may be scheduled in both portions of the study, as necessary, to ensure the 
safety and well-being of subjects. All additional examinations should be fully documented in the 
source files and eCRFs, as appropriate. Visits that fall outside the designated scheduled visit

14 Sep 2020 / Version 4 
Page 42 of 88 
window but that are intended to fulfill scheduled visit requirements will be collected and 
transcribed to the appropriate scheduled visit eCRF. 
If a subject is seen for multiple visits during a given visit time frame, the data from the visit(s) 
that are intended to meet the protocol requirements for the scheduled visit should be captured on 
the visit eCRF. Any other data from any additional visits within a scheduled visit interval will be 
captured elsewhere on the eCRF. 
6.5 
Post-study Follow-up 
Subjects who require further follow-up for an AE will be followed according to Section 8.4. If a 
subject requires further follow-up of AEs upon discontinuation or completion of the study, the 
investigator should schedule post-study follow-up visits, as necessary. 
6.6 
Missed Visits 
If a subject misses any scheduled follow-up visit and cannot be seen prior to the start of the visit 
range for the next scheduled follow-up visit, the visit is considered missed. 
6.7 
Subject Completion 
The subject has completed the study when the Test of Cure Visit is completed (Randomization 
Period of Enrollment A), or when the End of Treatment Visit is completed (Open-label 
Extension of Enrollment A or Enrollment B). Subjects who require further follow-up for an AE 
will be followed according to Section 8.4. 
6.8 
Early Study Termination 
The sponsor reserves the right to terminate this study prematurely. If during the study it becomes 
evident to the sponsor that the study should be stopped prematurely, the study will be terminated 
and appropriate notification will be given to the investigator, IRB, and FDA, as applicable. The 
sponsor or designee will instruct the investigator to stop screening/enrolling subjects, to bring all 
subjects who remain in the study (for example, subjects who are currently receiving treatment or 
who have completed treatment but have not yet completed the Test of Cure Visit in the 
Randomization Period, or subjects who have not completed the End of Treatment Visit in the 
Optional Open-label Extension or in Enrollment B) in for a final study visit as soon as possible, 
and to arrange for study closeout at the site. 
7 
STUDY PROCEDURES 
The required study procedures are detailed in this section. The timeline for these procedures is 
presented in Section 6. 
7.1 
Medical/Medication History 
At Screening/Baseline, the investigator or designee will interview each subject and obtain a 
complete medical and medication history, including a history of all surgeries and past medical 
procedures. The subject must not require any treatment or medication for concurrent illnesses as 

Hill Dermaceuticals, Inc.

14 Sep 2020 / Version 4 
Page 43 of 88 
specified by the inclusion and exclusion criteria or anticipate the need for any excluded 
concomitant medications. 
7.2 
Physical Examination 
At Screening/Baseline, the investigator or designee will perform a physical examination to 
include the following: general appearance; head, eyes, ears, nose, throat; neck; cardiovascular; 
lungs; abdomen; lymph nodes; extremities; neurological; skin; musculoskeletal; and body 
temperature. For subjects participating in Enrollment B, a physical examination of the treated 
ear(s) will also be performed at the End of Treatment Visit; a more extensive physical 
examination is not required for these subjects at the End of Treatment Visit but may be 
performed if necessary in the judgment of the investigator (e.g., to support evaluation of an AE). 
7.3 
Urine Pregnancy Test 
The urine pregnancy test (performed in females of childbearing potential only) must have a 
minimum sensitivity of 25 mIU of β-hCG/mL of urine. 
7.4 
Otomycosis Signs and Symptoms 
The signs and symptoms of otomycosis will be assessed according to the scales for pruritus (see 
Section 7.4.1), debris (see Section 7.4.2), presence of fungal elements (see Section 7.4.3), and 
aural fullness (see Section 7.4.4). The same evaluator should assess each subject for signs and 
symptoms of otomycosis at each visit throughout the subject’s participation in the study, if 
possible. 
7.4.1 
Pruritus 
Subjects or their caregivers (as appropriate, based on the age of the subject) will be asked by the 
investigator (or designee) about the severity of itching present in each ear being treated with 
study drug. Questions such as the following will be used in order to gather information for this 
assessment: 
“Over the last 24 hours, have you had itching in your ear?” 
“Over the last 24 hours, has your itching interfered with your daily activities?” 
“Over the last 24 hours, has your itching been bad enough to keep you awake?” 
“Over the last 24 hours, would you describe your itching as intolerable or constant?” 
The investigator will then score the symptom of pruritus for each ear being treated with study 
drug, taking into consideration the subject’s and/or caregiver’s answers and the investigator’s 
observations of the subject. Scores will be according to the following scale:

judgment are indicative of the presence of fungus 
7.4.4 
Aural Fullness 
Subjects or their caregivers (as appropriate, based on the age of the subject) will be asked by the 
investigator (or designee) whether aural fullness is present in each ear being treated with study 
drug. Questions such as the following will be used in order to gather information for this 
assessment: 
“Over the last 24 hours, have you had a feeling of fullness in your ear?”

7.5 
Fungal Culture 
At designated visits, the investigator or designee will obtain a sample from the external ear to be 
sent to a central laboratory for fungal culture. Techniques for obtaining and handling the sample 
and sending it to the laboratory will be described in a separate laboratory manual. If both ears 
will be treated with study drug, both ears will be cultured. 
The central laboratory will grow and identify fungal organisms from the sample provided by the 
investigator. The central laboratory will also test the susceptibility of the fungal isolates to 
miconazole. 
7.6 
Ear Cleaning 
At designated visits, the investigator or designee will clean the ear(s) that are being/have been 
treated with study drug, according to the site’s normal procedures. Ear(s) being treated will be 
cleaned at the designated visits even if they appear clear of debris. In cases in which the 
investigator would normally not clean the ear because it appears to be clear, this cleaning may be 
minimal. All ear cleaning will be documented in the eCRF.

Study Drug Administration 
See Section 9.1.1. 
7.10 Treatment Compliance 
Subjects or their caregivers (as appropriate) will complete a diary documenting each study drug 
administration. Additionally, each bottle of study drug will be weighed by the investigator or 
designee before dispensation to the subject and at each visit in which the used bottle is brought to 
the site. 
7.11 Protocol Deviations 
The IRB-approved protocol must be followed except in the case of a change that is intended to 
eliminate an immediate risk to subjects. 
The date of, nature of, and reason for deviations will be documented and explained by the 
investigator in all cases. Significant or major protocol deviations impacting the safety of the 
subject or the integrity of the study must be reported by the investigator to the sponsor and/or its 
designee and to the IRB immediately. Reporting of all other protocol deviations must adhere to 
the requirements of the governing IRB. 
All changes to the protocol will be made by the sponsor or designee as an approved amendment 
to the protocol, submitted to the FDA, and approved by the IRB prior to implementation. New or 
altered consent forms required by the IRB due to a protocol revision must be signed by all 
subjects currently enrolled in the study and must be used for any subsequent subject enrollment.

ADVERSE EVENTS 
8.1 
Definition of an Adverse Event 
An AE is any untoward medical occurrence in a subject or clinical investigation subject 
administered a study drug and which does not necessarily have a causal relationship with the 
study drug. An AE can therefore be any unfavorable and unintended sign (including a clinically 
significant abnormal laboratory finding), symptom, or disease temporally associated with the use 
of an investigational or marketed study drug, whether or not considered related to the 
investigational or marketed study drug. AEs include any illness, sign, or symptom that has 
appeared or worsened during the course of the clinical trial, regardless of causal relationship to 
the study drug. Study drug includes the investigational drug under evaluation and the comparator 
product. 
Medical conditions/diseases present before signing the informed consent form are only 
considered AEs if they worsen after the informed consent form is signed. 
AEs may be either spontaneously reported or elicited during questioning and examination of a 
subject. At each examination or visit, study personnel will ask each subject the following 
question, “Have you had any problems since we last spoke?” If known, the investigator should 
report the diagnosis of the underlying illness or disorder, rather than its individual symptoms. 

Hill Dermaceuticals, Inc. 
 
Protocol MZ-0120-ESP3-052 
 
 
14 Sep 2020 / Version 4 
Page 47 of 88 
The worsening or reoccurrence as compared to any previous visit in a subject of any symptom of 
otomycosis (including any increase in numerical score for pruritus and/or aural fullness 
according to the scales presented in Section 7.4, and/or any other symptom of otomycosis that 
worsens but is not captured in the scales presented in Section 7.4) should be reported as an AE. 
The diagnosis of the underlying disease or disorder should be reported as the AE, if known. For 
example, if the worsening symptom is believed to be due to otomycosis, the AE should be 
reported as “worsening of disease under study.” If the worsening symptom is believed to be due 
to some other cause (such as bacterial infection), that underlying illness or disorder should be 
reported as the AE. 
Debris and fungal elements are considered signs (manifestations) of otomycosis and minor 
changes are expected as a natural progression of the disease; therefore, minor changes in debris 
and fungal elements scores may not necessarily be captured as AEs if the changes are not 
clinically significant in the judgment of the investigator. If, however, in the investigator’s 
judgment there is a clinically significant worsening of debris and/or fungal elements, an AE of 
“worsening of disease under study” should be recorded. 
8.1.1 
Definition of a Serious Adverse Event 
An SAE is any untoward medical occurrence occurring at any dose that results in any of the 
following outcomes: 
• Results in death 
• Is life-threatening (defined as an event in which the subject was at risk of death at the 
time of the event; it does not refer to an event which hypothetically might have caused 
death if it were more severe) 
• Requires inpatient hospitalization or prolongation of existing hospitalization 
• Results in persistent or significant disability/incapacity 
• Is a congenital anomaly/birth defect 
• Is an important medical event (defined as a medical event(s) that may not be immediately 
life-threatening or result in death or hospitalization but, based upon appropriate medical 
and scientific judgment may jeopardize the patient/subject or may require medical or 
surgical intervention to prevent one of the other serious outcomes listed in the definition 
above). Examples of such events include but are not limited to: allergic bronchospasm 
requiring intensive treatment in an emergency room or at home; blood dyscrasia or 
convulsions that do not result in inpatient hospitalization; the development of drug 
dependency or drug abuse.  
Treatment on an outpatient emergency basis that does not result in hospital admission, or a 
hospitalization that is elective or is a preplanned treatment for a pre-existing condition that has 
not worsened since the start of the study, is not considered an SAE. 
8.2 
Severity of Adverse Events 
The severity of an AE will be determined by the investigator according to the following 
definitions: 

Hill Dermaceuticals, Inc. 
 
Protocol MZ-0120-ESP3-052 
 
 
14 Sep 2020 / Version 4 
Page 48 of 88 
• Mild: Awareness of event, but easily tolerated and does not disrupt usual activity 
• Moderate: Discomfort sufficient to cause interference with usual activity 
• Severe: Incapacitating, with inability to perform usual activities 
8.3 
Relationship of Adverse Events to Study Drug 
The relationship of AEs to the study drug will be assessed by the investigator according to the 
following definitions: 
• Not suspected: The temporal relationship of the event to the study drug makes a causal 
relationship unlikely, or, other drugs, therapeutic interventions or underlying conditions 
provide a sufficient explanation for the observed event. 
• Suspected: The temporal relationship of the event to the study drug makes a causal 
relationship possible or other drugs, therapeutic interventions or underlying conditions do 
not provide a sufficient explanation for the observed event. 
If there is any valid reason, even if undetermined, for suspecting a possible cause-and-effect 
relationship between the study drug and the occurrence of the AE, then the AE should be 
considered “suspected.” 
If the relationship between the AE and the study drug is determined by the sponsor to be 
“suspected,” the event will be considered to be related to the study drug for the purposes of 
expedited regulatory reporting. 
8.4 
Documentation of Adverse Events 
All AEs must be completely recorded on the Adverse Events section of the eCRF. The collection 
of AE information will begin after the subject has signed informed consent and continue up 
through the Test of Cure Visit (Randomization Period) or up through the End of Treatment Visit 
(Optional Open-label Extension or Enrollment B). Subjects experiencing AEs that cause 
interruption or discontinuation of study drug, or those experiencing AEs that are present at the 
end of their participation in the study or that resulted in permanent discontinuation will receive 
follow-up as appropriate until the AEs have either resolved or have stabilized. 
For each AE, the Investigator will evaluate and report the following: 
• Onset (date); 
• Resolution (date); 
• Severity grade (mild, moderate, severe); 
• Relationship to study drug (not suspected, suspected); 
• Action taken (none, study drug temporarily interrupted, study drug permanently 
discontinued, concomitant medication taken, hospitalization/prolonged hospitalization, 
other); 
• Serious (yes/no); 
• Whether the AE occurred at the study drug application site (yes/no);

• For AEs of the ear, which ear (left, right, or both) was affected. 
8.4.1 
Additional Reporting Requirements for Serious Adverse Events 
All SAEs that occur from the time the subject has signed the informed consent until the Test of 
Cure Visit (Randomization Period) or up through the End of Treatment Visit (Optional Open-
label Extension or Enrollment B) will be reported. Additionally, any SAEs “suspected” to be 
related to the study drug and discovered by the investigator at any time after the study should be 
reported. Each of these SAEs must be reported to the sponsor’s designee within 24 hours of the 
occurrence of the SAE, or within 24 hours of learning of the SAE. Information on recurrent 
episodes, complications, or progression of the initial SAE must also be reported within 24 hours 
of the investigator receiving the information.  
Reporting may be by telephone, confirmed facsimile transmission, or confirmed email to the 
medical monitor. The investigator must assess the relationship of the SAE to study drug and 
must complete the SAE form. If only limited information is initially available, follow-up reports 
are required. Follow-up information (e.g., discharge summary) will be retained in the subject’s 
chart and a copy (with the subject’s personal information removed and with the subject identified 
only by subject number) will be sent by confirmed facsimile transmission or confirmed email to 
the medical monitor. In the event of death, if an autopsy is performed, a copy of the report (with 
the subject’s personal information removed and with the subject identified only by subject 
number) should be sent to the medical monitor. 
As required and after the sponsor’s review and determination of causality, the sponsor and/or 
designee will notify investigators of all AEs that are serious, unexpected, and considered by the 
investigator to have a suspected relationship to the study drug. This notification will be in the 
form of an update to the Investigator’s Brochure (i.e., “15-day letter”). An AE, whether serious 
or non-serious, is designated unexpected (unlabeled) if it is not reported in the clinical safety 
section of the Investigator’s Brochure or if the event is of greater frequency, specificity or 
severity.  
Upon receiving such notices, the investigator must review and retain the notice with the 
Investigator’s Brochure and immediately submit a copy of this information to the responsible 
IRB according to local regulations. The investigator and IRB will determine if the informed 
consent requires revision. The investigator should also comply with the IRB procedures for 
reporting any other safety information. Follow-up reports should be submitted when requested or 
when pertinent information becomes available. 
The sponsor will report all SAEs to the US FDA on the appropriate schedule depending on the 
event’s expectedness and relationship to study drug based on the available information as 
presented in the Investigator’s Brochure.  
Any SAE occurring after the final study visit and which is not considered to be of “suspected” 
relationship to study drug does not need to be reported.

8.5 
Pregnancy 
Females of childbearing potential, as defined in Section 4.1.1 (Enrollment A) and Section 4.2.1 
(Enrollment B), must use an effective method of contraception from screening up through the 
final study visit. Acceptable methods include the use of at least one of the following: 1) IUD; 2) 
hormonal contraceptives (oral, injectable, implant, or ring); 3) barrier contraceptives (condom or 
diaphragm) with spermicide; or 4) abstinence. 
Should a pregnancy occur, it must be reported and recorded on the pregnancy form and sent by 
confirmed facsimile or confirmed email to the medical monitor, as well as documented in the 
eCRF. Pregnancy in itself is not regarded as an AE unless there is a suspicion that the study drug 
product may have interfered with the effectiveness of a contraceptive medication. 
In the event of pregnancy that is detected during treatment with study drug, the subject must be 
withdrawn from further treatment with study drug. The subject may continue to participate in the 
study on a case-by-case basis after discussion between the investigator and the sponsor and/or 
the sponsor’s designee. 
The outcome of all pregnancies (spontaneous miscarriage, elective termination, normal birth, or 
congenital abnormality) must be followed up and documented even if the subject was 
discontinued from the study and/or study drug.

Study Contacts 
Study contacts will be provided in a separate document.

STUDY TREATMENTS 
9.1 
Description of Study Drug 
Miconazole oil contains the active ingredient, 2% miconazole, formulated in an oil vehicle 
containing refined peanut oil, light mineral oil, oleth-2, and isopropyl myristate. For subjects 
randomized to the vehicle oil group, the vehicle oil will not contain miconazole and will instead 
contain a greater amount of refined peanut oil and mineral oil to account for the absence of the 
miconazole. 
Study drug will be supplied in bottles containing ~20 grams of product. The dispensing tip will 
deliver approximately 30 mg of product per drop. 
9.1.1 
Administration 
Subjects will be seated or lying on one side with the head positioned so the ear being treated is 
facing up. If both ears are being treated, the ear that appears to have less severe disease will be 
treated first. The subject or caregiver will gently pull the ear lobe backward and upward and 
apply 5 drops of study drug into the ear. The subject will be instructed to keep the head 
positioned with the ear facing up for approximately 3 to 5 minutes to allow the study drug to coat 
the ear canal. After this time, the subject can then straighten his/her head, and excess material 
dripping out of the ear can be gently patted using a clean cotton ball. 

Hill Dermaceuticals, Inc. 
 
Protocol MZ-0120-ESP3-052 
 
 
14 Sep 2020 / Version 4 
Page 51 of 88 
If both ears are being treated, the subject will then wait at least 5 minutes, then repeat this 
procedure for the second ear. 
During the Randomization Period, while on study treatment, subjects will be instructed to avoid 
getting water in the ear, to consider drying excessive water in the ear by using a blow dryer, and 
to place a Vaseline-impregnated cotton ball over the affected ear(s) to help keep water out of the 
ear(s) while bathing or showering. Subjects in the Optional Open-label Extension and subjects in 
Enrollment B who have signs and/or symptoms of otomycosis may also be given these 
instructions. 
Subjects in both portions will be asked to avoid bathing or showering for at least 30 minutes after 
applying study drug. 
9.2 
Randomization 
For the Randomization Period, subjects will be randomized in a 1:1 ratio to one of two groups: 1) 
14-day treatment with miconazole oil; or 2) 14-day treatment with miconazole oil vehicle. 
Randomization is not applicable to either the Optional Open-label Extension of Enrollment A or 
to Enrollment B. 
9.3 
Blinding/Unblinding 
The contents of the study drug (miconazole oil versus vehicle) will be blinded to both the 
investigator (and all study staff) and the subject during the Randomization Period of Enrollment 
A. Randomized study drug will be packaged in identical bottles and will be labeled with a 
randomization number rather than the contents of the bottle. 
If it becomes necessary to unblind a subject’s treatment assignment in case of emergency, the 
investigator should contact the sponsor. A person at the sponsor organization who is not 
otherwise involved with the study will maintain a randomization list that will enable that person 
to inform the investigator of the subject’s treatment allocation. The treatment allocation is to be 
obtained only if a medical emergency exists and knowledge of the medication being taken will 
influence the medical management of the subject. 
9.4 
Study Drug Handling and Dispensing 
9.4.1 
Packaging and Labeling 
The miconazole oil and the oil vehicle will be manufactured, packaged and labeled by Hill 
Dermaceuticals, Inc. It will be packaged in dropper bottles, each of which will contain ~20 
grams of study drug. The dropper will dispense approximately 30 mg per drop. 
For the Randomization Period of Enrollment A, the study drug and vehicle will be packaged in 
primary bottle and provided in identical study drug kits. Each kit will contain the investigational 
drug product (or placebo product), reserve identical drug product (or placebo product), bag of 
cotton balls, and Vaseline jelly. The subject will be dispensed the kit (minus the reserve product) 
at Baseline only. The dropper bottles will be weighed with the cap on prior to dispensing. If the

14 Sep 2020 / Version 4 
Page 52 of 88 
subject loses a bottle (lost or damaged), the reserve bottle will be dispensed using a replacement 
process as defined in the randomization plan.  
For the Optional Open-label Extension of Enrollment A and for Enrollment B, the study drug 
will be packaged in a primary bottle that will be dispensed directly to the subject. The dropper 
bottles will be weighed with the cap on prior to dispensing. If the subject loses a bottle (lost or 
damaged), a reserve bottle will be dispensed from the study drug inventory packaged for open-
label use. 
Each drug kit dispensed will be documented on the drug accountability log.  
Labels on the drug kit will contain the following information: 
• Protocol number 
• Subject number  
• Space for entry of the subject initials 
• Space for entry of date dispensed 
• A statement reading, “For otic use only. Avoid contact with eyes and lips” 
• A statement reading, “Store at controlled room temperature 20°C to 25°C (68°F to 77°F) 
with excursions permitted between 15°C to 30°C (59°F to 86°F)”  
• A statement indicating the sponsor, Hill Dermaceuticals 
• A statement indicating the quantity of product (20 grams) 
• A statement reading, “Caution: New Drug - Limited by Federal Law to Investigational 
Use” 
• A statement reading, “Keep out of Reach of Children” 
9.4.2 
Storage 
The study drug is to be stored at room temperature (20°C to 25°C, or 68°F to 77°F), with 
excursions permitted between 15°C and 30°C (59°F and 86°F). All investigational study drug 
must be stored in a secure facility, with access limited to the investigator and authorized staff. 
9.5 
Accountability 
The investigator or designee (e.g, study coordinator or pharmacist) is responsible for ensuring 
storage as per the label on the study drug and adequate accountability of all used and unused 
study drug. Adequate accountability includes acknowledgment of receipt of each shipment of 
study drug (quantity and condition), records of administration (including container number, date 
administered, subject number, and the initials of the person administering the drug), and 
documentation of quantities returned to the sponsor (or designee). 
At time points during the course of the study and/or upon completion of the study, the sponsor or 
designee will review and verify the investigator's accountability records.

Page 53 of 88 
9.6 
Return and Destruction 
At the completion of the study, following verification of the investigator’s accountability records 
by the sponsor and/or designee, all study drug must be returned to the sponsor or designee. This 
would include study drug returned by the subjects at the completion of the study, and reserve 
products that were not used. 
10 STATISTICAL CONSIDERATIONS 
All statistical processing will be performed using Statistical Analysis System (SAS®) Version 9.4 
or higher. Except where noted, all statistical tests will be two-sided and will be performed at the 
0.05 level of significance. 
Descriptive statistics will be used to provide an overview of the efficacy and safety results. For 
categorical parameters, the number and percentage of subjects in each category will be 
presented. For continuous parameters, descriptive statistics will include n (number of subjects), 
mean, and standard deviation, median, minimum, and maximum. 
Full details of statistical analyses will be provided in a separate statistical analysis plan. 
10.1 Study Endpoints 
10.1.1 
Primary Efficacy Endpoint 
The primary efficacy endpoint will be the percentage of subjects at the Test of Cure Visit with 
“therapeutic cure”, defined as “mycological cure” plus “clinical cure” for the study ear, at the 
end of the Randomization Period for each subject. Mycological cure is defined as a negative 
mycological culture, and clinical cure is defined as the absence of all otomycosis signs and 
symptoms based on investigator assessment according to the scales for each individual sign or 
symptom. See Section 7.4 for the scales for each otomycosis sign and symptom. 
10.1.2 
Secondary Efficacy Endpoints 
Secondary efficacy endpoints will include the following (each having been assessed at the end of 
the Randomization Period for each subject): 
• Percentage of subjects with mycological cure at the Test of Cure Visit. 
• Percentage of subjects with clinical cure at the Test of Cure Visit. 
10.1.3 
Tertiary Efficacy Endpoints 
Tertiary efficacy endpoints will include the following (each having been assessed at the end of 
the Randomization Period for each subject): 
• Percentage of subjects with “modified therapeutic cure” at the Test of Cure Visit, defined 
as mycological cure plus a score of 0 for the clinical sign of fungal elements plus a score 
of 0 or 1 for each of the clinical signs and symptoms of pruritus, debris, and aural 
fullness. 

Hill Dermaceuticals, Inc. 
 
Protocol MZ-0120-ESP3-052 
 
 
14 Sep 2020 / Version 4 
Page 54 of 88 
• Percentage of subjects with “therapeutic improvement” at the Test of Cure Visit, defined 
as mycological cure plus a score of 0 or 1 for each of the clinical signs and symptoms of 
fungal elements, pruritus, debris, and aural fullness. 
10.1.4 
Safety Endpoint 
A safety endpoint will be the percentage of subjects with treatment-emergent AEs (TEAEs), with 
treatment-emergent defined as occurring upon or after administration of the first dose of study 
drug. 
10.2 Hypotheses 
The primary efficacy endpoint of the study is percentage of subjects at the Test of Cure Visit 
with “therapeutic cure”, defined as “mycological cure” plus “clinical cure” for the study ear. 
Mycological cure is defined as a negative mycological culture, and clinical cure is defined as the 
absence of all otomycosis signs and symptoms based on investigator assessment according to the 
scales for each individual sign or symptom. 
Analysis is based on the following hypothesis:  
H0: pT – pV = 0  
H1: pT - pV > 0.  
where H0 is the null hypothesis, H1 the alternative hypotheses, and pT and pV are percentage of 
subjects with success in the Treatment (miconazole oil) and Vehicle (vehicle oil) groups, 
respectively. Comparisons between groups for the difference in the percentage of subjects 
achieving the primary endpoint of therapeutic cure will be conducted using a chi-square test with 
a 2-sided significance level of 0.05. 
Comparisons will also be conducted similarly between the miconazole oil and vehicle oil groups 
for the secondary endpoints of clinical cure, and mycological cure. 
10.3 Sample Size 
For the Randomization Period, approximately 128 subjects (~64 in each group) are required to 
provide 80% power, using a chi-square test with a 2-sided significance level of 0.05, assuming a 
response rate for the primary efficacy endpoint of 25.0% in the miconazole oil group and 7.1% in 
the vehicle oil group.  
The sample size of 220 subjects for Enrollment A assumes that ~58% of subjects enrolled into 
Enrollment A will have a positive fungal culture at Screening/Baseline and will therefore be 
included in the MITT population. This number may be higher or lower depending on the 
percentage of subjects eligible to be included in the MITT population. 
The estimated sample size of 170 subjects for Enrollment B is not based on statistical 
considerations and is instead based on the achievement of at least 300 subjects who have been 
exposed to miconazole oil for 14 days who are evaluable for safety (see also Section 3.4.2).

10.4 Study Populations 
10.4.1 
Intent-to-treat Population 
The intent-to-treat (ITT) population will be defined as all subjects who were randomized. 
10.4.2 
Modified Intent-to-treat Population 
The modified intent-to-treat (MITT) population will be a subset of the ITT population. The 
MITT population will include subjects in the ITT population with a positive fungal culture at 
Screening/Baseline. The MITT population will be the primary population to assess efficacy. 
10.4.3 
Per Protocol Population 
The per protocol (PP) population will be a subset of the MITT population and will include all 
subjects who complete the Test of Cure visit without any major protocol violations. The PP 
population will include subjects in the MITT population who did not meet any of the following 
criteria: 
• Violated the inclusion/exclusion criteria 
• Used an interfering concomitant medication 
• Did not attend the Test of Cure visit 
• Did not attend the End of Treatment visit 
• Have not been compliant with the dosing regimen (i.e., subjects must have received 
80%-120% of the expected applications of study medication in the study ear during 
participation in the study) 
• Out of visit window at the Test of Cure Visit (-1/+8 days) 
Subjects who discontinue from the study due to an adverse event related to study treatment, 
documented lack of treatment effect, or worsening of condition will be included in the PP 
population. Prior to breaking the blind, other additional criteria may be added to the list to 
accommodate for unforeseen events that occurred during the conduct of the trial that result in 
noteworthy study protocol violations. 
All efficacy analyses will be performed using the PP population in a supportive manner. 
10.4.4 
Safety Population 
Two safety populations will be defined. 
The Randomization Period safety population will include all subjects who received at least one 
dose of study drug and had at least one post-Baseline safety assessment during the 
Randomization Period.  

Hill Dermaceuticals, Inc. 
 
Protocol MZ-0120-ESP3-052 
 
 
14 Sep 2020 / Version 4 
Page 56 of 88 
The Open Label safety population will include all subjects who received at least one dose of 
miconazole oil and had at least one post-Baseline safety assessment during the Optional Open-
label Extension or Enrollment B. 
Safety analyses for the Randomization Period will be performed using the Randomization Period 
safety population. Safety analyses for the Optional Open-label Extension and Enrollment B will 
be combined and presented using the Open Label safety population. 
10.5 Statistical Methods 
10.5.1 
Efficacy Analyses 
The primary population for efficacy analyses will be the MITT population (see Section 10.4). 
Efficacy analyses will also be performed on the ITT and the PP populations and will be 
considered supportive. 
The primary analysis will be conducted once Enrollment A is complete. 
The number and percent of subjects who demonstrate a positive outcome for the primary efficacy 
outcome as well as all secondary and tertiary efficacy outcomes will be presented. 
The primary endpoint, defined as the percentage of subjects at the Test of Cure Visit with 
“therapeutic cure”, will be compared between groups using a chi-square test with a 2-sided 
significance level of 0.05. 
The secondary endpoints will be analyzed analogously to the primary endpoint. 
In Enrollment A in cases of bilateral otomycosis, if only 1 ear has a positive fungal culture at 
Screening/Baseline, that ear will be used as the study ear for efficacy analyses. If both ears have 
a positive fungal culture at Screening/Baseline, the ear with the worse infection at 
Screening/Baseline, as assessed by the investigator by taking into account clinical signs and 
symptoms, will be used as the study ear for efficacy analyses. If both ears have a positive fungal 
culture at Screening/Baseline and are determined by the investigator to have the same degree of 
infection at Screening/Baseline, the left ear will be used as the study ear for the purposes of 
efficacy analyses. 
Descriptive statistics will be provided for otomycosis signs and symptoms and also for clinical 
cure, modified therapeutic cure, and therapeutic improvement; each at Day 15 will be 
summarized using the ITT population for both the Randomization Period and the Optional Open-
label Extension. 
10.5.1.1 
Multiple Comparison/Multiplicity 
The overall Type I error will be controlled by requiring the primary efficacy endpoint to be 
statistically significant. Specifically, failure of the primary efficacy endpoint will invalidate the 
statistical significance of the secondary efficacy endpoints. 

Hill Dermaceuticals, Inc. 
 
Protocol MZ-0120-ESP3-052 
 
 
14 Sep 2020 / Version 4 
Page 57 of 88 
Evaluation of the secondary efficacy endpoints will use a gated sequential procedure in order to 
control for multiplicity. These tests will be performed for only the MITT population. The testing 
process will terminate whenever a statistical test for a step is not significant, i.e., any subsequent 
test will be considered not significant. The order of testing is: 
1. Percentage of subjects with mycological cure at the Test of Cure Visit. 
2. Percentage of subjects with clinical cure at the Test of Cure Visit. 
10.5.2 
Safety Analyses 
Safety summaries will be conducted using two safety populations (see Section 10.4.4). All AEs 
occurring during the study will be recorded and classified using terminology from the Medical 
Dictionary for Regulatory Activities (MedDRA). All reported treatment-emergent adverse events 
(TEAEs), defined as any AE with an onset on or after the date of first study drug application, 
will be summarized. Summaries will provide the number of subjects reporting TEAEs, system 
organ class, preferred term, severity, and relationship to study drug. When summarizing TEAEs 
by severity or relationship to study drug, each subject will be counted only once within a system 
organ class or a preferred term using the event with the greatest severity or causality, 
respectively, within each category. All reported SAEs will be summarized by the number of 
subjects reporting the event, system organ class, preferred term, severity, and relationship to 
study drug. 
Summaries will be provided separately for the blinded and unblinded portions. Specifically, 
summaries will be provided by treatment group for the Randomization Period using the 
Randomization Period safety population, and for all open-label subjects using the Open Label 
safety population. 
All information pertaining to AEs noted during the study will be listed by study portion 
(Enrollment A or Enrollment B), study period (Randomization or Optional Open-label), as 
applicable, treatment group, and subject and will include a verbatim description of the event as 
reported by the investigator, as well as the preferred term, system organ class, start date, stop

13 SUMMARY OF PROTOCOL AMENDMENTS 
13.1 Amendment 1 Version 2 04 February 2020 
The purpose of this amendment was to remove the following secondary endpoints: 
• Percentage of subjects with mycological cure at the Test of Cure Visit 
• Percentage of subjects with clinical cure at the Test of Cure Visit. 
No detailed summary of changes was prepared for Version 2 because the prior version (Version 
1, 28 January 2020) was internal only. 
13.2 Amendment 2 Version 3 18 May 2020 
This amendment reflects updates and revisions to the protocol resulting from an End-of-Phase 2 
meeting with FDA and changes in sponsor strategy for the development of miconazole oil. An 
overview of major changes is as follows. 
• An optional open-label extension was added to the study to allow subjects the option to be 
treated with active drug (miconazole oil) if they have a visual presence of fungal elements in 
at least one ear following randomized treatment. 
• A second portion was added to the study (called Enrollment B), which will commence after 
completion of the first portion (called Enrollment A) in order to gather safety information for 
miconazole oil in additional subjects. Because the purpose of Enrollment B is safety, subjects 
in Enrollment B are not required to have a diagnosis of otomycosis. 
• Secondary and tertiary efficacy endpoints were added. 
Clarifications and minor changes to study conduct and statistical analyses were also made. 
A more complete summary of changes from the prior version is provided below. Insertions are 
bolded. Deletions are struck through. For sections that are new or have been completely revised, 
only a short description is provided.

(Administration) 
The subject or caregiver will gently pull the ear 
lobe backward and upward and apply 5 drops of 
study drugmiconazole oil into the ear. The 
subject will be instructed to keep the head 
positioned with the ear facing up for 
approximately 3 to 5 minutes to allow the study 
drugmiconazole oil to coat the ear canal.

Section 9.1.1 
(Administration) 
During the Randomization Period, 
whileWhile on study treatment, subjects will be 
instructed to avoid getting water in the ear, to 
consider drying excessive water in the ear by 
using a blow dryer, and to place a Vaseline-
impregnated cotton ball over the affected ear(s) 
to help keep water out of the ear(s) while 
bathing or showering. Subjects in the Optional 
Open-label Extension and subjects in 
Enrollment B who have signs and/or 
symptoms of otomycosis may also be given 
these instructions.
