• The proportion of subjects with at least a 2-grade reduction 
from the Baseline IGA score at Day 14, Day 28 and Day 56, 
and 
• The proportion of subjects with an IGA score of “clear” or 
“almost clear” at Day 14, Day 28 and Day 56 and at least a 2-
grade reduction from the Baseline IGA score. 
• The change from Baseline in the Acne-QoL at Day 84, and 
• Subject’s assessment of the change in their acne from Baseline 
to Day 84 (Patient Reported Outcome [PRO]).     
The safety outcome measures to be assessed are: 
• Adverse events (AEs) reported from time of consent/assent 
through the end of the study. 
• Complete blood count (CBC), chemistry, and urinalysis 
conducted at Baseline and at Day 84. 
Cutaneous tolerability (erythema, scaling, dryness, pruritus, and 
burning/stinging) will be assessed at the Baseline, Day 14, Day 28, Day 
56 and Day 84 Visits.  Cutaneous tolerability will be graded using the 
following scale: 0, None; 1, Slight; 2, Moderate; 3, Severe.   
Pregnancy testing will be conducted for women of child-bearing 
potential (WOCBP) at the Screening Visit, the Baseline Visit (if > 7 
days from Screening Visit) and at the Day 28, Day 56 and Day 84 
Visits. 
Total Sample Size:  
Subjects will be randomized 2:2:2:1:1 (BTX 1503 5% BID:BTX 1503 
5% QD:BTX 1503 2.5% QD:Vehicle BID:Vehicle QD) with 90 
subjects in each BTX 1503 group and 45 subjects in each vehicle group 
for a total of 360 subjects.    
Methods: 
Subjects will begin screening to determine eligibility to participate in 
the study. At the Screening Visit, informed consent/assent, medical 
history/review of systems, demographics, height and weight, 
tobacco/alcohol history, concomitant medications, and a urine 
pregnancy test (UPT) for WOCBP will be obtained.  A urine drug 
screen (UDS) will be performed.  In addition, lesion counts on the face 
(inflammatory and non-inflammatory lesions counted separately) and 
an IGA will be conducted to assess subject eligibility.  Subjects will be 
12 to 40 years of age with moderate to severe acne vulgaris of the face

CONFIDENTIAL 
(20 to 50 inflammatory lesions, 20 to 100 non-inflammatory lesions, 
and an IGA score of 3 or 4).  
If a subject is deemed eligible, they may be enrolled and begin Baseline 
assessments (within 35 days after the Screening Visit).  Assessments 
for safety (CBC, chemistry, and urinalysis) will be obtained at the 
Baseline Visit (Day 1). If the Screening and Baseline Visits are not 
conducted on the same day, lesion counts, IGA, UDS, and a review of 
concomitant medications will be repeated.  A UPT for WOCBP will be 
repeated if greater than 7 days from the Screening Visit.  Baseline 
photographs of the face (selected sites) will be obtained.  The Acne-
QoL will be administered.  Clinical site staff will apply the first dose of 
study drug.  Cutaneous tolerability assessments will be conducted prior 
to and approximately 15 minutes after the first application. Subjects 
will be given a diary and sufficient study drug to last until their Day 28 
Visit and instructed in the proper application to cover their entire face.  
Subjects will return to the clinic on Day 14 for a review of their diary 
to ensure compliance with study drug applications.  Lesion counts, IGA 
and cutaneous tolerability assessments will be conducted.  In addition, 
the subject will apply study drug during the visit for the clinical site to 
confirm correct application techniques.  AEs and concomitant 
medications will be reviewed.   
Subjects will return to the clinic on Day 28 and Day 56 for cutaneous 
tolerability assessments, UPT, lesion counts and IGA.  Subjects will 
also be queried for AEs and changes in concomitant medications.  
Diaries and study drug will be returned and reviewed for compliance.  
In addition, the subject will apply study drug during the visit for the 
clinical site to confirm correct application techniques.  Study drug will 
be dispensed along with the diary for the next 28 days of study drug 
treatment.       
Subjects will return to the clinic for their final visit on Day 84 for safety, 
tolerability and efficacy assessments, including lesion counts and IGA 
scoring of facial acne.  Safety labs (CBC, chemistry, and urinalysis) and 
a UPT for WOCBP will be obtained.  Photographs of the face will be 
obtained at selected sites.  Cutaneous tolerability assessments will be 
conducted, and concomitant medications and AEs will be reviewed. 
The Acne-QoL and a patient reported outcome (PRO) will be 
administered at Day 84, assessing the subject’s perception of the change

in their acne relative to Baseline.  See Table 3 for full Schedule of 
Assessments. 
Statistical Methods 
Analysis Sets: 
This study will be evaluated using 3 analysis sets: intent-to-treat (ITT), 
per protocol (PP), and safety.  Efficacy conclusions will be drawn from 
the ITT analysis set.  The PP analysis set will be used to support the 
efficacy findings in the ITT analyses.  Safety conclusions will be drawn 
from the safety analysis set. 
Demographics will be summarized using the safety analysis dataset by 
age, gender, race, ethnicity, height and weight.  The primary efficacy 
analysis will be conducted on the ITT population using last observation 
carried forward (LOCF) for missing data.  For continuous variables, the 
mean, standard deviation (SD), median, and range will be presented 
along with the 95% confidence interval (CI).   Categorical variables 
will be summarized by proportions along with the 95% CI. 
Vehicle QD and Vehicle BID groups may be combined for analyses. 
Handling of Missing Data: 
The primary method of handling missing efficacy data in the ITT 
analysis set will be based on LOCF.  Other imputation methods (e.g., 
mixed model for repeated measurement [MMRM]) may be used as a 
sensitivity analysis.  
All safety analyses will be conducted using the safety analysis set. No 
imputations will be made for missing safety data. 
Efficacy Analyses: 
The efficacy analyses will be performed using the ITT (primary) and 
PP (supportive) analysis sets. The efficacy variables include the IGA 
and lesion counts (inflammatory and non-inflammatory) collected at 
Screening/Baseline and all subsequent study visits. The primary 
efficacy endpoint is the absolute change in inflammatory lesion count 
at Day 84.   
Absolute and percent changes in lesion counts from Baseline will be 
calculated for each subject at Day 14, Day 28, Day 56 and Day 84.  The 
IGA will be dichotomized into “success” and “failure” at study Day 14, 
Day 28, Day 56, and Day 84 with a subject considered a “success” at 
each individual visit if the IGA at that visit is Clear (“0”) or Almost

Protocol BTX.2018.001 Version 2.4

CONFIDENTIAL 
Clear (“1”) and at least 2 grades less than the Baseline score.  
Exploratory efficacy assessments also include the Acne-QoL which 
will be scored according to the author’s scoring system (Martin 2001), 
and the subject’s assessment of improvement (PRO) using proportions 
by category. 
Descriptive statistics (including mean, median, standard deviation 
[SD], minimum, and maximum, unless otherwise stated) will be 
presented for the following parameters by study group using both the 
ITT and PP analysis sets: 
• Inflammatory, non-inflammatory, and total lesion counts at 
Baseline, Day 14, Day 28, Day 56, and Day 84, 
• Absolute and percent change from Baseline in inflammatory, 
non-inflammatory, and total lesion counts at study Day 14, Day 
28, Day 56, and Day 84, 
• IGA scores and frequency and percent distribution of the 
dichotomized IGA at study Day 14, Day 28, Day 56, and Day 
84. 
This Phase 2 study is designed to identify the response to two different 
dosing frequencies and two concentrations of BTX 1503. Statistical 
tests applied to the outcomes will be exploratory.  No adjustments for 
Type 1 error will occur. 
The change from Baseline in lesion counts (inflammatory and non-
inflammatory; separate and combined, and total) at Days 14, 28, 56, 
and 84 will be analyzed using ANCOVA with Baseline lesion count 
and treatment as covariates.  Success on IGA defined as a score of clear 
or almost clear and/or at least a 2-grade improvement from Baseline at 
Day 14, Day 28, Day 56, and Day 84 will be analyzed using logistic 
regression, adjusting for Baseline IGA.   
Safety Analyses:  
All subjects who receive at least one confirmed dose of study drug and 
have at least one post-Baseline assessment will be included in the safety 
analyses. Safety analyses will include summaries of treatment-
emergent adverse events (TEAEs), serious AEs (SAEs), and changes in 
laboratory assessments.  TEAEs and SAEs will be summarized by 
treatment group, the number of subjects reporting events, system organ 
class, preferred term, severity, relationship to study drug, and

seriousness. A list of subjects who prematurely discontinue from the 
study due to an AE and the reason for discontinuation will be provided. 
The number and percentage of subjects reporting each medication will 
be summarized.  Medications taken by each subject will be listed. 
Cutaneous Tolerability:  
Cutaneous tolerability (erythema, scaling, dryness, pruritus, and 
burning/stinging) will be summarized by treatment group at the 
Baseline, Day 14, Day 28, Day 56, and Day 84 Visits.  Cutaneous 
tolerability will be graded using the following scale: 0, None; 1, Slight; 
2, Moderate; 3, Severe. 
Sample Size: 
The sample size for this study is based on clinical considerations only. 
Subjects will be randomized 2:2:2:1:1 with 90 subjects in each active 
treatment group and 45 in each vehicle group for a total 360 subjects. 
This is considered adequate to evaluate the safety and tolerability of 
BTX 1503 in the treatment of acne vulgaris.

2. INTRODUCTION: BACKGROUND AND SCIENTIFIC RATIONALE 
2.1. Background Information 
Botanix Pharmaceuticals' BTX 1503 containing the active pharmaceutical ingredient, cannabidiol 
(CBD; 2-[(1R,6R)-6-isopropenyl-3-methylcyclohex-2-en-1-yl]-5-pentylbenzene-1,3-diol) in a 
topical liquid formulation, is being developed for the treatment of acne vulgaris.  CBD is a member 
of a broader family of compounds known as cannabinoids, a class of compounds originally derived 
from the cannabis sativa plant.1 CBD is chemically synthesized under Good Manufacture Practices 
(GMP) for use in this study. 
Synthetic CBD is not psychoactive and clinical trials have demonstrated that CBD may 
successfully treat epilepsy, arthritis, pain, and even Fragile X Syndrome.2  Interest in CBD-based 
therapeutics has increased significantly in recent years, as published data has highlighted the 
potential efficacy and safety benefits of this compound.3  There are now more than 100 human 
clinical trials that have been completed, are underway, or pending recruitment around the world 
that are studying CBD in a range of diseases.4  
No known well-controlled, human clinical studies have ever been conducted using CBD to treat 
skin disease, and no CBD containing pharmaceuticals have been approved to treat skin disease. 
Researchers have found that CBD may play a beneficial role in regulating the cutaneous 
endocannabinoid system by decreasing unwanted skin cell growth, sebum production and skin 
inflammation associated with many human skin diseases.1   
2.2. Rationale 
2.2.1. Mechanism of Action 
This study is intended to establish preliminary safety and tolerability in subjects with acne vulgaris 
treated with BTX 1503.  The rationale for the use of BTX 1503 in acne is provided herein. 
Acne is the most common skin disease in the world and is characterized by partial obstruction of 
the pores and associated local skin lesions that can appear on the face, chest or back.5,6  Obstructed 
pores can become enlarged and inflamed as sebum and its breakdown products accumulate, 
resulting in visible lesions that can be unsightly and cause permanent scarring.5,6 Acne usually 
begins in puberty and affects many adolescents and young adults, but it can occur at any stage of 
life.  Approximately 85 percent of people between the ages of 12 and 24 experience at least minor 
acne.7 Acne often causes significant physical and psychological problems such as permanent 
scarring, poor self-image, depression and anxiety.8  
Acne lesions are believed to result from an interaction of four primary pathogenic factors: 
• the excessive production of sebum or lipids by sebaceous glands in the skin;  
• hyper-proliferation of keratinocytes that contribute to clogging of pores through which 
sebum is normally released to the skin surface;

• colonization of the area in and around the sebaceous gland by bacteria; and  
• inflammation, often associated with colonization by bacteria and their breakdown of sebum 
into irritating breakdown products.1  
For many years, treatment of acne has been dominated by the same four prescription 
pharmaceutical product classes:  
i. 
Antimicrobials.  Antimicrobials for acne treatment target bacterial colonization and 
inflammation and are widely used topically and, in more severe disease, orally.8  While 
antimicrobials have been shown to be effective, there is a growing interest in limiting the 
use of antibiotics in acne, because of concerns regarding bacterial resistance.9,10,6  
ii. 
Retinoids.  Topical retinoids address some of the changes in skin cells that contribute to 
clogging of the pores and are among the most commonly used prescription acne 
medications. Their limitations include skin irritation, photosensitization, and relatively 
modest efficacy in comparison with systemic therapies.10  
iii. 
Isotretinoin.  Oral isotretinoin (marketed initially as Accutane or Roaccutane) operates to 
significantly reduce sebum production and is indicated for the treatment of severe 
recalcitrant nodular acne.  Even in the case of very severe disease, the efficacy of oral 
isotretinoin can be significant, with large proportions of patients achieving partial or 
complete clearance, after one course of therapy.8,11 However, oral isotretinoin is associated 
with significant systemic toxicity, including liver damage and severe birth defects, which 
largely limit its use as second line treatment in  patients with severe disease who enroll in 
a monitoring program intended to restrict distribution of the drug. Mood disorders, 
depression, suicidal ideation and suicides have been reported in patients taking oral 
isotretinoin, but a causal relationship has not been established.8,12,13,14,15  
iv. 
Hormonal therapies.  Oral agents that reduce the activity of sex hormones (called 
androgens) are also highly effective, as these treatments also reduce sebum production.16 
Hormonal therapies have well-known systemic side effects, such as mood disturbance, loss 
of muscle mass and reduced sexual desire, that are related to their effects on sex hormones 
(they are most often used in the form of contraceptives). As such, they are not widely used 
in men or in women not seeking contraception.17  
No topical treatments are currently available which target all the above pathogenic factors.18  Acne 
treatment guidelines recommend that acne treatment be directed toward as many of the four 
primary pathogenic factors as possible.19  Accordingly, patients are often treated with combination 
regimens that incorporate multiple agents with complementary mechanisms of action targeting 
different pathogenic factors.20  While systemic therapies (such as isotretinoin) may inhibit sebum 
production, their use is limited by significant systemic side effects. An unmet need remains for 
effective therapies that are not associated with antibiotic resistance or treatment-limiting side 
effects, particularly therapies with novel mechanisms of action.9

BTX 1503 is focused on modulating the body's endocannabinoid system of receptors which 
regulate skin function, growth and renewal.21  It is understood that CBD may play a significant 
role in normalizing unwanted skin growth, reducing excessive production of oils and reducing 
inflammation and infection, amongst other functions.1  Botanix Pharmaceuticals is exploring 
whether endocannabinoid modulating drugs (such as synthetic CBD) can be exploited in the 
management of acne.  
BTX 1503 is a formulation of active synthetic CBD and inactive excipients designed to deliver a 
consistent dose of CBD to directly treat patients with acne. It is considered that CBD may: 
• normalize excessive lipid synthesis of human sebocytes  
• decrease proliferation (but not the viability) of these human sebocytes; 
• inhibit hyperproliferation of keratinocytes; 
• exert anti-inflammatory actions; and 
• have anti-bacterial effects.1,22  
2.2.2. Nonclinical and Clinical Data  
Nonclinical information on the safety pharmacology, pharmacokinetics and metabolism, and 
toxicology profiles of CBD has been extensively reported in the scientific literature.  The clinical 
safety of CBD has also been established and reviewed in the published scientific literature.  
Clinical investigations with CBD have been reported in both normal subjects and patients, 
including treatment of individuals with oral doses of up to 300 mg/day (5 mg/kg/day or 185 
mg/m2/day, for an individual with an average body weight of 60 kg).  Higher oral doses of up to 
1,500 mg/day (25 mg/kg/day or 925 mg/m2/day) have been reported to be well tolerated.  CBD 
formulated as a topical gel (Zynerba Pharmaceuticals) for treatment of epilepsy has also been 
shown to be safe and well-tolerated with only mild, transient application site AEs observed.  
Botanix Pharmaceuticals has conducted a Phase 1a single and multiple-ascending dose study (BTX 
2017.001) of BTX 1503 in normal healthy volunteers in Australia involving 20 subjects.  This 
study demonstrated that daily topical treatment with up to 3.75 mg/kg/day (225 mg CBD/day or 
0.398 mg/cm2/day1) applied as 3 mL of BTX 1503 5% (w/w) BID for 14 days was safe and well-
tolerated. Forty-two (42) AEs were reported in 18 of the 20 participants.  All AEs were reported 
as mild except one moderate vasovagal reaction to cannula insertion for blood draws (unrelated).  
Facial dryness and itchiness were the most frequently reported related AEs.  One subject reported 
application site stinging, and one subject reported stinging in the eyes after accidental transfer of 
BTX 1503 into the eyes.  
In a subsequent Australian Phase1b open-label study (BTX.2017.002) of BTX 1503 in subjects 
with moderate to severe acne involving 21 subjects, daily topical treatment with up to 3.75 
                                                 
1 Area of application assumed to be 565 cm2 (i.e., on the face), which is reported by the European Union Scientific Committee on 
Consumer Safety (SCCS) to be half of the surface area for a female head (SCCS Notes of Guidance for the Testing of Cosmetic

mg/kg/day (225 mg CBD/day or 0.398 mg/cm2/day) applied as 3 mL of BTX 1503 5% (w/w) BID 
for 28 days was shown to be safe and well-tolerated. There was only 1 AE associated with the 
study drug treatment; application site pain (sore eyes).  Slight to moderate erythema was reported 
most frequently in cutaneous tolerability assessments.  However, most subjects that reported 
erythema pre or post-study drug application had erythema at Baseline and treatment with BTX 
1503 did not exacerbate the erythema.  Only 1 subject had increased erythema from Baseline and 
this was reported at Day 35, seven days after their final application of study drug.  Slight scaling 
was reported in 2 subjects (9.5%), slight dryness was reported in 4 subjects (19.0%) and slight 
burning/stinging was reported in 5 subjects (23.4%).  Only 1 positive cutaneous tolerability 
assessment (slight dryness) was reported at more than a single visit.   
In support of this planned Phase 2 clinical study, dermal toxicology studies of 90 days in duration 
in minipigs with BTX 1503 have not revealed any clinically significant toxicities or laboratory 
abnormalities. Details on the results of these studies are provided in the Investigator’s Brochure. 
The published literature has suggested that CBD may be an inhibitor of human cytochrome P450 
CYP1A1 at concentrations that are 9.7-fold of observed maximum plasma concentrations (Cmax) 
in clinical studies with BTX 1503. 
The testes was the only target organ for toxicity identified in published studies in rats and monkeys: 
effects on sperm maturation were observed in a 25-day inhalation study in male rats [no-observed-
adverse-effect level (NOAEL) of less than 0.6 mg CBD/kg/day (< 3.6 mg/m2/day) and lower testis 
weights and inhibition of spermatogenesis were observed at a daily oral dose of 300 mg/kg 
CBD/kg/day (3,600 mg/m2/day) in male monkeys.  However, there were no changes in testis 
weight nor microscopic findings in the testes following 28 days of oral dosing in male rats at doses 
up to 400 mg/kg/day with the CBD to be used in the BTX 1503 formulations.  The Area Under the 
Concentration (AUC) exposures are over 1000-fold higher than reported in clinical studies 
involving BID dosing with BTX 1503.  In addition, there were no changes in testis weight nor 
microscopic correlates in the testes following 90 days of dermal dosing in minipigs using 
BTX 1503 at doses up to 150 mg/kg/day (AUC exposures in males at least 24-fold higher then 
observed in clinical studies with BTX 1503).  
2.3. Rationale for Study 
This study is designed to investigate the efficacy, safety and tolerability of BTX 1503 in subjects 
with moderate to severe acne.  In this study, BTX 1503 will be applied at 3 different dosage 
regimens and compared against a Vehicle control.  The treatment period will be 12 weeks to 
coincide with the FDA’s recommended minimum treatment duration to demonstrate efficacy.

2.4. Potential Risks and Benefits 
2.4.1. Known Potential Risks 
Based on studies conducted by Botanix Pharmaceuticals, the potential risks associated with BTX 
1503 include: 
• Ocular irritation 
• Local application site AE’s 
• Cutaneous reactions which may include erythema, dryness, scaling, and burning/stinging.   
Facial dryness and facial itchiness were reported as possible effects of study drug treatment in 
Botanix Pharmaceuticals’ healthy volunteer study (BTX.2017.001).  In the current study, subjects 
will be allowed to use their usual moisturizers.  Subjects in this study will be given instructions on 
what to do if BTX 1503 liquid accidentally gets into the eyes.   
In the BTX.2017.002 study, slight to moderate erythema was reported most frequently in 
cutaneous tolerability assessments.  However, most subjects that reported erythema pre-or post-
study drug application had erythema at Baseline and treatment with BTX 1503 did not exacerbate 
the erythema.  Only 1 subject had increased erythema from Baseline and this was reported at 
Day 35, seven days after their final application of study drug.  Slight scaling was reported in 2 
subjects (9.5%), slight dryness was reported in 4 subjects (19.0%) and slight burning/stinging was 
reported in 5 subjects (23.4%).  Only one positive cutaneous tolerability assessment (slight 
dryness) was reported at more than a single visit.      
In the published scientific literature, the only target organ for toxicity that has been identified was 
the testes in rat and monkey studies.  It is uncertain if the reduction in spermatogenesis noted in 
these animal studies has a clinical correlate.  In addition, this finding was not observed in the 28-
day oral rat study or in a 90-day dermal minipig study conducted with Botanix Pharmaceuticals’ 
BTX 1503.   
The other aspect of systemic exposure to CBD reported in the published scientific literature was 
the potential for competitive binding to CYP450 isozymes, indicating a potential for drug-drug 
interactions.  Given the limited systemic exposure observed in Botanix Pharmaceuticals’ healthy 
volunteer study, the potential for a drug-drug interaction is considered to be minimal.  
2.4.2. Known Potential Benefits 
Non-clinical data suggests BTX 1503 may target pathways relevant in pathogenesis of acne.  
Activity of BTX 1503 was observed in the BTX.2017.002 study in subject with moderate to severe 
acne.  Statistically significant improvements from Baseline in inflammatory and non-inflammatory 
lesion counts were observed.  Improvements were also observed in the IGA and in the PRO. 
Although improvements in acne were observed in this 28-day treatment study, the benefit of 
BTX 1503 in patients with 12 weeks of treatment is unknown.

6. STUDY DRUG 
6.1. Study Drug  
6.1.1. Acquisition 
Study drug will be provided to the US study sites by The Coghlan Group (TCG) in Bastrop, Texas, 
USA and to the Australian sites by Pharmaceutical Packaging Professionals (PPP) in Port 
Melbourne, Victoria, Australia.  Initial shipments will be made to supply the study sites prior to 
enrollment of the first subject. Additional supplies will be made available as needed based on 
subject enrollment.  
6.1.2. Formulations, Appearance, Packaging, and Labeling 
Botanix Pharmaceuticals’ BTX 1503 contains the active pharmaceutical ingredient, cannabidiol 
(CBD).  CBD is a member of a broader family of compounds known as cannabinoids, a class of 
compounds originally derived from the cannabis sativa plant.1  CBD is chemically synthesized 
under Good Manufacturing Practices (GMP) for use in this study. 
The active study product is a clear to light yellow, slightly viscous liquid with a 2.5% or 5% (w/w) 
concentration of CBD in a formulation of excipients which have been used extensively in other 
topical products.  The liquid spreads easily and quickly evaporates, leaving the CBD and a small 
amount of excipients on the skin.  The Vehicle liquid is identical in appearance to the BTX 1503 
liquid.   
Each milliliter of the BTX 1503 5% liquid formulation contains 37.5 mg of CBD.  Each milliliter 
of the BTX 1503 2.5% liquid formulation contains 18.75 mg of CBD.  All subjects will apply 2.0 
mL, 4 pump actuations, of BTX 1503 BID or QD or Vehicle BID or QD based on their randomized 
treatment group.  Subjects will receive the following daily exposure to CBD. 
• Subjects randomized to BTX 1503 5% BID will apply 150.0 mg of CBD daily,    
• Subjects randomized to BTX 1503 5% QD will apply 75.0 mg of CBD daily,    
• Subjects randomized to BTX 1503 2.5% QD will apply 37.5 mg of CBD daily. 
Study drug will be supplied in 60 mL multi-dose, metered pumps delivering 0.5 mL per actuation.  
Each pump for BID dosing will contain approximately 39 mL of study drug and each pump for 
QD dosing will contain approximately 21 mL of study drug.  This will provide dosing for 7 days 
for all subjects.  Pumps for all groups will be labeled identically, except for kit number and bottle 
number, to maintain the blind.   
Study drug will be pumped into the palm of one hand and applied to the face using fingertips of 
the other hand.  Study drug will be applied to the entire face, regardless of location of acne lesions.   
Study drug will be provided in kits.  Each kit will contain adequate study drug for 4 weeks of daily 
applications (28 days).  Prior to distribution, pumps will be weighed by clinical site staff and the 
weights recorded in the source documents and the eCRF.  Each kit will contain 4 pumps, one for

each week of dosing.  When a subject is enrolled, the site will access the IWRS to receive a kit 
number for the first 28 days of dosing based on the IWRS randomization.  At the Day 28 and Day 
56 Visits, the site will access the IWRS to obtain the kit number for the following 28 days of 
dosing.  All distributed pumps will be returned by the subject at the Day 28, Day 56, and Day 84 
Visits and weighed to monitor compliance and document doses delivered.   
The study drug bottle may include the following information:

6.1.3. Product Storage and Stability 
The study drug will be stored at a controlled room temperature of 15°C to 30°C and should not be 
refrigerated.  Prior to dispensing to the subject, the study drug will be stored in a secured location 
with access only by authorized study personnel.  Study drug has been tested to ensure that there is 
adequate stability for the duration of the study.   Retest dates may be included on the carton 
labeling. 
6.1.4. Preparation 
No preparation of the study drug is required.   
6.1.5. Dosing and Administration 
Subjects will receive their initial application of study drug on Day 1 at the clinical sites 
administered by the clinical site staff.  When the subject is ready for study drug application, a 
pump is selected from the assigned study kit.  The clinical site staff will remove the cap and apply 
the first dose of the study drug to the subject’s entire face.   All subsequent applications will be 
completed by the subject.   To ensure that the entire face is covered, the study drug should be 
applied in a consistent manner for each application.   
Subjects will be instructed in how to apply study drug.  After their first application in the clinic 
subjects will apply their study drug at home.  Each application of study drug will occur at the 
approximately the same time in the morning with the second application (for BID dosing groups) 
approximately 8 to 12 hours later.  Subjects will apply study drug at the clinical site during the 
Day 14, Day 28, Day 56 and Day 84 Visits (final dose).  A diary will be maintained documenting

compliance with the self-administered applications.  All study drug bottles (used and unused) will 
be returned to the clinical site on the Day 28, Day 56, and Day 84 Visits. 
Study drug should not be applied to the eyes or mouth.   Subjects are to thoroughly wash their 
hands after study drug application.  The study drug must not be handled by a family member or 
caregiver for study drug application. 
6.1.6. Starting Dose  
The dose for all subjects will be 2.0 mL, 4 pump actuations, of study drug applied to the entire 
face.  No escalation of dose will occur.     
6.1.7. Dose Adjustments/Modifications/Delays 
There are no pre-planned dose adjustments, modifications, or delays.      
6.1.8. Duration of Therapy 
Subjects will apply study drug for 84 days with a final application on Day 84.  Subjects receiving 
BID dosing will apply 167 doses and subjects receiving QD dosing will apply 84 doses.   
6.1.9. Tracking of Dose 
All subjects will be required to maintain a diary documenting each application of study drug.  The 
subject will record that they applied each study dose.  Subjects will return the study drug bottles 
(used and unused) at each visit.  The clinical site staff will review the diary and count used/unused 
bottles to ensure subject compliance with dosing.   
6.2. Study Drug Accountability Procedures 
At each study visit the clinical site will weigh each pump dispensed to the subject and returned 
from the subject to calculate the amount (grams) of study drug used.  The investigator will keep a 
current and accurate inventory of all clinical supplies received.  These records will be reviewed at 
each monitoring visit performed by the CRA per SOPs.

7.4. Concomitant Medications, Treatment and Procedures 
All concomitant medications taken during study participation will be recorded on the case report 
forms (eCRFs). For this protocol, a prescription medication is defined as a medication that can be 
prescribed only by a properly authorized/licensed clinician. Medications to be reported in the 
eCRF are concomitant prescription medications, OTC medications, and non-prescription 
medications.  In addition, vitamins, supplements and other non-pharmaceuticals products that are 
taken orally are to be reported in the eCRF.  Any use of marijuana products will be reported. 
Subjects will use their normal facial cleansers throughout the study.  The face will be washed daily 
with these cleansers.  Subjects will be instructed to wash their face prior to the Baseline, Day 14, 
Day 28, Day 56, and Day 84 Visits.  The face will not be washed within 5 minutes prior to, or 
within 1 hour after application of study drug.  Subjects must agree to maintain their regular use of 
sunscreens, moisturizers, and facial makeup throughout the entire course of the study.  Sunscreens, 
moisturizers and makeup may be applied to the face after study drug has adequate time to dry.  
Detailed dosing instruction will be provided to the subjects. 
7.5. Prohibited Medication, Treatment, and Procedures 
The following medications, treatments, and procedures are prohibited for all subjects during the 
study.   
• Use of topical acne treatments or other topical medication on the face  
• Shaving cream and cleansers cannot be used within 5 minutes prior to, or for 1 hour after 
application of study medication 
• Participation in a clinical study of any investigational product or procedure 
• Use of any medications, other than the study drug, for treatment of acne vulgaris 
• Use of any medication that, in the opinion of the investigator, may affect the evaluation of 
the study product (e.g., tetracycline or macrolide for > 7 days for URI) or place the subject 
at undue risk 
• Use of oral retinoids (e.g., isotretinoin) or high dose (> 10,000 IU) Vitamin D  
• Use of systemic corticosteroids (inhaled or intranasal corticosteroid ≤ 1000 µg daily dose 
is acceptable), oral antibiotics, or anti-inflammatory drugs (occasional NSAIDs to treat 
ailments other than acne are permitted)

8. ASSESSMENT OF SAFETY 
8.1. Specification of Safety Parameters 
8.1.1. Definition of Adverse Events (AE) 
An AE is defined as any untoward medical occurrence in a study subject which does not 
necessarily have to have a causal relationship with the study treatment.  An AE can therefore be 
any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or 
disease temporally associated with the use of study drug treatment, whether or not considered 
related to the study drug.   
Any events involving illnesses or injuries with onset during the study or any events involving 
exacerbations of pre-existing illnesses should be recorded.  All clearly related signs and symptoms 
should be grouped together and recorded as a single diagnosis in the eCRF.  A pre-existing 
condition will not be reported as an AE unless the condition worsens during the trial.  The 
condition, however, must be reported in the Medical History section of the eCRF. Scheduled or 
planned diagnostic and therapeutic procedures such as surgery will not be reported as AEs.   
8.1.2. Definition of Serious Adverse Events (SAE) 
Each AE will be independently judged by the investigator in terms of seriousness.  A serious AE 
(SAE) is defined as any untoward medical occurrence that: 
• Results in death,  
• Is life-threatening, 
Note: The term “life-threatening” in the definition of “serious” refers to an event in which 
the subject was at risk of death at the time of the event; it does not refer to an event which 
hypothetically might have caused death if it were more severe. 
• Requires inpatient hospitalization or prolongation of existing hospitalization, 
• Results in permanent impairment of a body function or permanent damage to a body 
structure,  
• Is a congenital anomaly/birth defect,  
• Necessitates medical or surgical intervention to preclude any one of the outcomes listed in 
this definition.

Protocol BTX.2018.001 Version 2.4 
07-June-2018 
CONFIDENTIAL 
8.2. Classification of Adverse Events 
8.2.1. Relationship to Study Drug 
The investigator will review each event and assess its relationship (unrelated, unlikely, possibly, 
probably, definitely) to drug treatment.  The following definitions will be used for these causality 
assessments. 
Unrelated 
• The AE must clearly be caused by the subject’s clinical state, or the 
study procedure/conditions. 
• Definitely not related to drug. 
• Temporal sequence of an AE onset relative to administration of drug 
not reasonable. 
• Another obvious cause of an AE. 
Unlikely 
• Time sequence is unreasonable. 
• There is another more likely cause for an AE. 
Possibly 
• Corresponds to what is known about the drug. 
• Time sequence is reasonable. 
• Could have been due to another equally, likely cause. 
Probably 
• Is a known effect of the drug. 
• Time sequence from taking drug is reasonable. 
• Ceases on stopping the drug. 
• Cannot be reasonably explained by the known characteristics of the 
subject’s clinical state. 
Definitely 
• Is a known effect of the drug (e.g., listed in Investigator’s Brochure). 
• Time sequence from taking drug is reasonable. 
• Event stops upon stopping drug, event returns upon restarting drug. 
NOTE: Re-challenge will only be considered after consultation with 
the medical monitor and the sponsor.

Protocol BTX.2018.001 Version 2.4 
07-June-2018 
CONFIDENTIAL 
8.2.2. Severity of Event 
Each sign or symptom reported will be graded on a 5-point severity scale (Grade 1, 2, 3, 4 and 5). 
The following definitions for rating maximum severity will be used: 
Grade 1 
 
Mild; asymptomatic or mild symptoms; clinical or diagnostic observations 
only; intervention not indicated. 
Grade 2 
 
Moderate; minimal, local or noninvasive intervention indicated; limiting 
age-appropriate instrumental activities of daily living.* 
Grade 3  
 
Severe or medically significant but not immediately life-threatening; 
hospitalisation or prolongation of hospitalisation indicated; disabling; 
limiting self-care activities of daily living.** 
Note: An experience may be severe but may not be serious, (e.g., severe 
headache). 
Grade 4 
Life-threatening consequences; urgent intervention indicated. 
Grade 5 
Death related to AE. 
Note:  A semi-colon indicates ‘or’ within the description of the grade. 
*Instrumental activities of daily living refer to preparing meals, shopping for groceries or clothes, using the 
telephone, managing money, etc. 
**Self-care activities of daily living refer to bathing, dressing and undressing, feeding self, using the toilet, taking 
medications, and not bedridden. 
8.2.3. Expectedness 
For this study, all AEs will be recorded.   
The safety and tolerability of BTX 1503 5% was evaluated in a Phase 1a study in healthy 
volunteers and in a Phase 1b study in subjects with moderate to severe acne vulgaris.  These studies 
demonstrated that BTX 1503 5% was safe and well tolerated with up to 3 mL applied BID (225 
mg CBD daily) for up to 28 days.  Adverse events reported as related to study drug treatment were 
facial dryness and itchiness. Mild cutaneous reactions included erythema, dryness, scaling, and 
burning/stinging.   
Studies of the active ingredient (CBD) administered orally in multiple therapeutic settings has 
described no consistent findings for systemic AEs.  Based on findings in a cumulative irritation 
study of the BTX 1503 vehicle, mild skin irritation may occur. 
8.3. Time Period and Frequency for Event Assessment and Follow-up 
All AEs occurring after signing of the consent/assent form through completion of the Day 84 Visit 
will be recorded.  AEs arising after the time of initiation of first treatment with study drug will be 


 
 
Page 49 
Protocol BTX.2018.001 Version 2.4

CONFIDENTIAL 
considered treatment emergent AEs (TEAEs).  At each contact with the subject, the investigator 
or designee will seek information on AEs by non-leading specific questioning and, as appropriate, 
by examination.  All observed or volunteered AEs, regardless of suspected causal relationship to 
study drug, must be recorded on the AE page of the eCRF. 
The occurrence of an AE or SAE may come to the attention of study personnel during study visits 
and interviews of a study subject presenting for medical care, or upon review by a study monitor. 
All AEs including local and systemic reactions will be recorded. All AEs occurring while on study 
must be documented appropriately regardless of relationship. All AEs will be followed to 
resolution or considered stable by the investigator.  
Changes in the severity of an AE will be documented to allow an assessment of the duration of the 
event at each level of severity to be performed. AEs characterized as intermittent require 
documentation of onset and duration of each episode. 
8.4. Reporting Procedures 
8.4.1. Adverse Events Reporting 
All AEs will be recorded on the AE eCRF.  For each AE, the name of the event, date of onset, 
relationship to study drug, severity, seriousness (Y/N), whether a medication was used to treat the 
event, date of resolution (or ongoing), and outcome (fatal, recovered/resolved, recovered/resolved 
with sequelae, ongoing) will be noted. 
8.4.2. Serious Adverse Event Reporting 
Each AE will be independently judged by the investigator in terms of seriousness.  A SAE is 
defined in Section 8.1.2.  
All SAEs will be reported to the sponsor via fax or e-mail within 24 hours of becoming aware of 
the event, whether or not the serious events are deemed drug-related.  All serious event reporting 
will adhere to 21 CFR 312.32 for Investigational New Drugs (IND) and to the Guidance for 
Industry 
and 
Investigators: 
Safety 
Reporting 
Requirements 
for 
INDs 
and 
Bioavailability/Bioequivalence, dated December 2012. The IRB/EC will be notified of the Alert 
Reports. 
All AEs will be followed until resolution or until the investigator determines that the subject’s 
status has returned to normal or has stabilized. 
8.4.3. Reporting of Pregnancy 
As part of the eligibility criteria, WOCBP must agree to use appropriate contraception methods to 
avoid pregnancy during the study.  If a subject does become pregnant, or is suspected of being 


 
 
Page 50 
Protocol BTX.2018.001 Version 2.4 
07-June-2018 
CONFIDENTIAL 
pregnant, the subject will be immediately withdrawn from any further treatment with the study 
drug.  The pregnancy, or suspected pregnancy will be immediately reported to the medical monitor. 
Any subject that becomes pregnant during the study will be followed to term to collect pregnancy 
outcomes pending acquisition of the subject’s permission.   
8.5. Safety Oversight 
Oversight of the safety of the study will be the responsibility of the medical monitor.  Safety data 
will be regularly reviewed (monthly at a minimum).  If unexpected safety signals are observed, 
the medical monitor and the sponsor will determine if the enrollment or the study should be 
discontinued, or the protocol amended to include additional safety monitoring.

9. STATISTICAL CONSIDERATIONS 
9.1. Statistical and Analytical Plans 
A separate Statistical Analysis Plan (SAP) will be prepared for this study.  The statistical 
approaches to analysis of the data are described in this protocol.  Further detail on the structure of 
tables, listings, and figures is provided in the SAP.   
9.2. Statistical Hypotheses 
The purpose of this Phase 2 study is to describe the safety and efficacy of treatment with the BTX 
1503 5% liquid formulation or 2.5% liquid formulation vs Vehicle liquid formulation with QD or 
BID dosing in subjects with acne vulgaris.  P-values for selected variables will be presented to 
assist in evaluating the outcome of the study. Failure to achieve a statistically significant result 
does not imply a failed study; results from this study will be used to inform statistical approaches 
for registration studies.   
The primary efficacy endpoint of the study is the change from Baseline in inflammatory lesion 
counts.  The study will evaluate the superiority of active study drug over vehicle based on the 
following hypotheses:  
H0: µactive - µvehicle = 0  
H1: µactive - µvehicle > 0. 
Where H0 is the null hypothesis, H1 the alternative hypotheses, µactive is the absolute change in the 
number of inflammatory lesions counts from Baseline to Day 84, and µvehicle is the absolute change 
in the number of inflammatory lesions counts from Baseline to Day 84.   
Secondary and exploratory endpoints do not have a priori hypotheses but will be evaluated using 
appropriate statistical methods to inform statistical approaches for future studies. 
9.3. Analysis Datasets 
This study will be evaluated using 3 analysis sets: intent-to-treat (ITT), per protocol (PP), and 
safety.  Efficacy conclusions will be drawn from the ITT analysis set.  The PP analysis set will be 
used to support the efficacy findings in the ITT analyses. Safety conclusions will be drawn from 
the safety analysis set. 
The ITT analysis set includes all subjects who are randomized and is based on randomized study 
group, regardless of study drug received.  The safety analysis set includes all subjects who are 
randomized, receive at least 1 confirmed dose of study drug, and have at least 1 post-Baseline 
assessment.  The safety analysis set will be assessed based on study drug received, regardless of 
group to which subject was randomized.  The PP analysis set includes all subjects in the ITT 
analysis set who complete the Day 84 visit without noteworthy study protocol violations, including 
compliance with study drug application, Day 84 visit window, and completion of efficacy

CONFIDENTIAL 
evaluations on Day 84.  The full definition of the PP population is given in the SAP which will be 
approved prior to database lock. 
Subjects who have a documented lack of treatment effect or who are discontinued from the study 
due to an AE that was considered by the investigator to be study drug related will be included in 
the PP analysis set.  Specific criteria for identifying the PP analysis set will be determined prior to 
breaking the blind.    
Vehicle QD and Vehicle BID groups may be combined for analyses. 
9.4. Description of Statistical Methods 
9.4.1. General Approach 
All statistical processing will be performed using SAS® 9.3 or higher. Demographics will be 
summarized by age, gender, race, ethnicity, height and weight.  Summary statistics will be 
presented for change from Baseline in lesion counts (inflammatory and non-inflammatory separate 
and combined) and IGA.  For continuous variables, the mean, standard deviation (SD), median, 
and range will be presented.   Categorical variables will be summarized by frequency counts and 
percentages.  
9.4.2. Safety Analyses 
All subjects who receive at least one confirmed dose of study drug and have at least one post-
Baseline assessment will be included in the safety analyses.  
All treatment-emergent adverse events (TEAEs) reported during the study will be recorded and 
classified based on MedDRA terminology. Treatment-emergent adverse events are those AEs with 
an onset on or after the first application of study medication. All reported TEAEs will be 
summarized by treatment group, the number of subjects reporting events, system organ class, 
preferred term, severity, relationship to study drug, and seriousness. When summarizing events by 
causality and severity, each subject will be counted only once within a system organ class or a 
preferred term by using the event with the greatest relationship and highest severity within each 
classification. 
Serious adverse events (SAEs) will be summarized by cohort, system organ class, preferred term, 
severity, outcome and relationship to study drug; and all SAEs will be listed by subject. In addition, 
a list of subjects who prematurely discontinue from the study due to an AE and the reason for 
discontinuation will be provided. 
Concomitant medication will be mapped to ATC Level 2 using the WHODrug dictionary.  The 
number and percentage of subjects reporting each medication will be summarized.  Medications 
taken by each subject will be listed.

Changes from Baseline in safety laboratory assessments (CBC, chemistry and urinalysis) at 
Day 84 will be summarized using shift tables.  Abnormal values will be summarized.  Laboratory 
values will be listed by subject.   
Cutaneous tolerability will be assessed at the Baseline, Day 14, Day 28, Day 56 and Day 84 Visits.  
Summaries will present frequencies and percentages for the grading of each of the signs/symptoms 
that was performed at each scheduled visit/time point combination.  The summary of cutaneous 
tolerability assessment scores table will present summary statistics for the scores (‘None’=0, 
‘Slight’=1, ‘Moderate’=2 and ‘Severe’=3) and the change from Baseline values at each scheduled 
post-Baseline visits/time point for each of the signs/symptoms.  Listings will be provided by 
subject.   
9.4.3. Efficacy Analyses 
The efficacy analyses will be performed using the ITT (primary) and PP (supportive) analysis sets. 
The efficacy variables include the IGA and lesion counts (inflammatory and non-inflammatory) 
collected at Screening/Baseline and the Day 14, Day 28, Day 56, and Day 84 Visits.  Absolute and 
percent changes in lesion counts from Baseline will be calculated for each subject.  The IGA will 
be dichotomized into “success” and “failure”, with a subject considered a “success” at each 
individual visit if the IGA at that visit is Clear (“0”) or Almost Clear (“1”) and at least 2 grades 
less than the Baseline score.  Efficacy variables also include the Acne-QoL assessed at Baseline 
and Day 84 which will be scored according to the author’s scoring system (Martin 2001), and the 
subject’s assessment of improvement (PRO) using proportions by category. 
Descriptive statistics (including mean, median, standard deviation [SD], minimum, and maximum, 
unless otherwise stated) will be presented for the following parameters by study group using both 
the ITT and PP analysis sets: 
• Inflammatory, non-inflammatory, and total lesion counts at Baseline and study Day 14, 
Day 28, Day 56, and Day 84, 
• Absolute and percent change from Baseline in inflammatory, non-inflammatory, and total 
lesion counts at study Day 14, Day 28, Day 56, and Day 84, and 
• IGA scores and frequency and percent distribution of the dichotomized IGA at study Day 
14, Day 28, Day 56, and Day 84. 
Primary endpoint: 
The primary efficacy endpoint for the study is: 
• Absolute change from Baseline in inflammatory lesion counts at Day 84. 
Secondary endpoints:   
The secondary endpoints for the study are: 
• Absolute change from Baseline in non-inflammatory lesion count at Day 84,

• The percent change from Baseline in the inflammatory lesion count at Day 84,  
• The percent change from Baseline in the non-inflammatory lesion count at Day 84,  
• The proportion of subjects with at least a 2-grade reduction from the Baseline IGA score 
at Day 84, 
• The proportion of subjects with an IGA score of “clear” or “almost clear” at Day 84, and 
• The proportion of subjects with an IGA score of “clear” or “almost clear” at Day 84 and 
at least a 2-grade reduction from the Baseline IGA score. 
Exploratory endpoints: 
The exploratory endpoints are: 
• The change from Baseline in the total lesion count at Day 84,  
• The percent change from Baseline in the total lesion count at Day 84, 
• The change from baseline in the IGA scores and Day 84, 
• The absolute and percent change from Baseline in inflammatory, non-inflammatory and 
total lesion counts at Day 14, Day 28 and Day 56. 
• The proportion of subjects with at least a 2-grade reduction from the Baseline IGA score 
at Day 14, Day 28 and Day 56, and 
• The proportion of subjects with an IGA score of “clear” or “almost clear” at Day 14, 
Day 28 and Day 56, 
• The proportion of subjects with an IGA score of “clear” or “almost clear” at Day 14, 
Day 28 and Day 56 and at least a 2-grade reduction from the Baseline IGA score. 
• The change from Baseline in the Acne-QoL at Day 84, and 
• Subject’s assessment of the change in their acne from baseline to Day 84 (PRO). 
Tests of superiority for the primary and secondary endpoints of absolute change from Baseline in 
lesion counts will be based on either parametric or nonparametric methods consistent with the 
statistical assumptions required to support the analyses. Specifically, the tests of superiority will 
be based on an ANCOVA with factors of treatment and the respective Baseline lesion count as 
covariates, or on ranked data submitted to an ANCOVA with factors of treatment, analysis center, 
and the respective Baseline lesion count as a covariate.   
Data will be reviewed for skewedness (details in the SAP).  If a parametric analysis is indicated, 
the results of the parametric analysis will be considered the primary analysis.  If a nonparametric 
analysis is indicated, the absolute or percent changes in inflammatory lesion counts will be rank-
transformed prior to submitting them to the ANCOVA. Results of the rank-transformed analyses

will then be considered the primary analysis; results of the nonrank-transformed analyses will be 
also presented. 
The dichotomized IGA will be analyzed with logistic regression, adjusting for baseline IGA and 
site.  Pairwise tests will be conducted comparing the treated groups to vehicle.  The lesion count 
and IGA analyses employ the methods for handling missing data described in Section 9.4.9. 
9.4.4. Subset analyses  
Subset analyses will be conducted for the primary efficacy endpoint. These analyses will be 
summarized using descriptive statistics.  The specific subsets within the ITT analysis set that will 
be evaluated include: Baseline lesion counts, Baseline IGA, sex, age, ethnicity, race, and for the 
group less than the median age and greater than or equal to the median age. 
9.4.5. Adherence and Retention Analyses 
Compliance with study drug administration will be summarised based on dosing information from 
the clinical sites along with diary information obtained from subjects self-administering the study 
drug.  Subjects who drop-out from the study for any reason will be summarised.   
9.4.6. Baseline Descriptive Statistics 
Demographics will be summarised by age, gender, race, ethnicity, height, and weight.  Alcohol 
and tobacco history will be summarised, 
9.4.7. Planned Interim Analyses 
No interim analysis is planned.   
9.4.8. Multiple Comparison/Multiplicity 
This Phase 2 study is designed to identify the response to two different concentrations and dosing 
frequencies of BTX 1503. Statistical tests applied to the outcomes will be exploratory for 
establishing the dose and sample size for Phase 3 studies.   No adjustments for Type 1 error will 
occur. 
9.4.9. Handling of Missing Data 
All efforts will be made to minimize the occurrence of missing data. It is not expected that dropout 
rates will differ between groups.  Therefore, the primary method of handling missing efficacy data 
in the ITT analysis set will be based on last observation carried forward (LOCF). 
Other imputation methods (e.g., MMRM) may be used as a sensitivity analysis to the LOCF 
method.

CONFIDENTIAL 
All safety analyses will be conducted using the safety analysis set. No imputations will be made 
for missing safety data.   
Additional details on imputation and sensitivity analyses are provided in the SAP. 
9.4.10. Tabulation of Individual Response Data 
Individual response data will be presented in data listings.     
9.5. Sample Size 
The sample size for this study is based on clinical considerations only.  Subjects will be 
randomized 2:2:2:1:1 with 90 subjects in each active treatment group and 45 subjects in each 
vehicle group for a total 360 subjects. This is considered adequate to evaluate the safety and 
tolerability of BTX 1503 in the treatment of acne vulgaris. 
9.6. Measures to Minimize Bias 
9.6.1. Enrollment/Randomization/Masking Procedures 
 A randomization code will be prepared by an unblinded statistician at the CRO.  This statistician 
will be the only person aware of the randomization code.  Randomization will be 2:2:2:1:1 (90 
subjects in each active group and 45 in each vehicle group) and done by site.  Once a subject is 
deemed eligible to enroll, randomization will occur.  The site will contact the IVRS/IWRS to 
receive the kit number to be used for that subject throughout the study.   
Study drug, active or vehicle, will be labelled identically except for the kit number and bottle 
number.  Study drug pumps will contain approximately 39 mL for BID dosing groups and 
approximately 21 mL for QD dosing groups. There is no double-dummy in this study for BID vs 
QD dosing, so knowledge of volumes (during study drug accountability) will not unmask treatment 
groups (active vs vehicle). The vehicle study drug is indistinguishable from the active study drug.     
9.6.2. Evaluation of Success of Blinding 
For this Phase 2 study, no analyses to evaluate the success of the blinding will be conducted.  
Subjects known to have been unblinded during the study will be addressed in the final analysis as 
described in the SAP.    
9.6.3. Breaking the Study Blind/Subject Code 
During the study, the randomization code will not be broken except in the case of a safety concern, 
either for an individual subject or for the entire study. 
If a subject has an adverse event that may necessitate unblinding of the randomization code, the 
site will contact the CRO and sponsor to discuss if there are options other than unblinding.  If the 
site and sponsor agree that unblinding is in the best interests of the subject, the unblinded 
statistician will be contacted to conduct the unblinding.  For circumstances where the CRO or

Protocol BTX.2018.001 Version 2.4 
07-June-2018 
CONFIDENTIAL 
sponsor cannot be contacted, and the subject is in imminent danger without knowledge of their 
treatment, unblinding can be done through the IVRS/IWRS system.     
At the completion of the study, the blind will be broken only after all data on all subjects has been 
entered into the database and the database is locked.  Database lock procedures will follow the 
CRO’s SOPs.

10. SUPPORTING DOCUMENTATION AND OPERATIONAL CONSIDERATIONS 
This research will be carried out in accordance with the protocol, the ICH harmonized tripartite 
guideline regarding GCP (E6 Consolidated Guidance, June 1996), the National Statement on 
Ethical Conduct in Human Research (updated May 2015), and the ethical principles set forth in 
the Declaration of Helsinki. 
10.1. 
Regulatory, Ethical, and Study Oversight Considerations 
10.1.1. Informed Consent/Assent Process 
It is the responsibility of the investigator, or a person designated by the investigator (if acceptable 
by local regulations), to obtain written informed consent/assent from each subject participating in 
this study after adequate explanation of the aims, methods, objectives and potential hazards of the 
study.  It must also be explained to the subjects that they are completely free to refuse to enter the 
study or to withdraw from it at any time for any reason.  In states or institutions where permission 
is required from a legal guardian and the child is required to assent to participate, the appropriate 
assent-permission process will be followed according to the relevant local and/or state laws.  
Appropriate IRB/EC-approved forms for obtaining written informed consent/assent will be 
provided by the investigator or by the sponsor or its designee.   
The case report forms for this study contain a section for documenting informed consent/assent 
and this must be completed appropriately.  If new safety information results in significant changes 
in the risk/benefit assessment, the consent/assent form will be reviewed and updated if necessary.  
All subjects (including those already being treated) will be informed of the new information, given 
a copy of the revised form and be re-consented/assented to continue in the study. 
10.1.2. Institutional Review Board (IRB)/Ethics Committee (EC) 
This protocol, the informed consent/assent form and any accompanying material provided to the 
subject (such as subject information sheets or descriptions of the study used to obtain informed 
consent/assent) as well as any advertising or compensation given to the subject, will be reviewed 
by the IRB/EC, and the study will not start until the IRB/EC has approved the protocol or a 
modification thereof.  The IRB/EC is constituted and operates in accordance with the principles 
and requirements described in 21 CFR 56, ICH E6, and the National Statement on Ethical Conduct 
in Human Research (updated May 2015).  
Protocol modifications to this study must be made only after consultation between an appropriate 
representative of the sponsor and the investigator.  Protocol amendments must be prepared and 
approved by the sponsor and reviewed and approved by the IRB/EC prior to implementation. 
10.1.3. Subject and Data Confidentiality 
Subject confidentiality is strictly held in trust by the participating investigators, their staff, and the 
sponsor(s) and their agents. This confidentiality is extended to cover testing of biological samples 


 
 
Page 59 
Protocol BTX.2018.001 Version 2.4 
07-June-2018 
CONFIDENTIAL 
in addition to the clinical information relating to subjects. Therefore, the study protocol, 
documentation, data, and all other information generated will be held in strict confidence. No 
information concerning the study or data will be released to any unauthorized third party without 
prior written approval of the sponsor.  
The study monitor, other authorized representatives of the sponsor, or representatives of the 
IRB/EC may inspect all documents and records required to be maintained by the investigator, 
including but not limited to, medical records (office, clinic, or hospital) and pharmacy records for 
the subjects in this study. The clinical study site will permit access to such records.  
The study subject’s contact information will be securely stored at each clinical site for internal use 
during the study. At the end of the study, all records will continue to be kept in a secure location 
as described in Section 10.1.9.  
Study subject research data, which is for purposes of statistical analysis and scientific reporting, 
will be transmitted to and stored at the CRO. This will not include the subject’s contact or 
identifying information. Rather, individual subjects and their research data will be identified by a 
unique study identification number. The study data entry and study management systems used by 
clinical sites and by the clinical sites’ research staff will be secured and password protected. At 
the end of the study, all study databases will be de-identified and archived at the CRO and 
ultimately with the sponsor. 
10.1.4. Research Use of Stored Human Samples, Specimens or Data 
Samples and data collected under this protocol will be used to study the safety of the study drug, 
BTX 1503 liquid formulation. No genetic testing will be performed.  Samples and data will be 
stored using codes assigned by the clinical study site, the CROs, and/or the laboratories assessing 
the samples. Data will be kept in password-protected computers. Only those entities participating 
in the study will have access to the samples and data.  
The study involves taking digital photographs of the subject’s face at selected sites. The subject or 
subject’s parent/guardian will consent/assent, in advance of any photographs being taken, to the 
taking, copyright, publication, and use of their photographs.  The subject’s eyes will be masked to 
conceal their identity. The photographs will be part of the study record and will be sent to the 
sponsor and regulatory agencies. The photographs will only be linked to the subject’s study code 
and not the subject’s name.   
10.1.5. Future Use of Stored Specimens 
All blood and urine samples used for assessment or study drug safety will be destroyed after 
analysis.  No specimens will be stored for future use. 
10.1.6. Key Roles and Study Administration 
The sponsor of this study is Botanix Pharmaceuticals Ltd (Botanix).  Botanix has engaged Premier 
Research (Durham, North Carolina, US) to oversee the conduct of the study.  Premier will conduct 


 
 
Page 60 
Protocol BTX.2018.001 Version 2.4 
07-June-2018 
CONFIDENTIAL 
the data management, clinical monitoring and statistical management of the study.  The medical 
monitor for this study will be provided by Premier.  His/her responsibility will be to oversee the 
safety of subjects in the study.   
The IRB/EC, which protects the rights and welfare of subjects, will be either local or centralized 
based on the study site.  Central IRBs will be preferentially used when possible.  Clinical sites 
outside of the US, will have IRB/EC oversight based on local and national requirements. 
Photography of facial acne at selected sites will be performed utilizing equipment from a 
photography vendor.  The vendor will provide a Photography Manual describing correct 
techniques for photographing subjects.  Photographs from the study are the property of Botanix 
and will become part of the study record.   
Study drug will be manufactured in the United States.  The Coghlan Group (TCG; Bastrop, Texas, 
USA) is responsible for packaging, labeling, and distribution of the study drug.  
A qualified vendor will act as the central lab for analysis of the blood and urine samples.  Results 
will be provided to the sites for their subject management and to Premier for data analysis.   
There will be no DSMB for this study.  Blinded safety data will be reviewed in real-time by the 
medical monitor to assure subject safety. 
10.1.7. Clinical Monitoring 
Clinical site monitoring is conducted to ensure that the rights and well-being of human subjects 
are protected, that the reported trial data are accurate, complete, and verifiable, and that the conduct 
of the study is in compliance with the currently approved protocol/amendment(s), with GCP, and 
with applicable regulatory requirement(s).  
Monitoring for this study will be performed by a CRO contracted by the sponsor to conduct this 
activity.  
On-site monitoring will occur for initial site assessment and training throughout the study and at a 
frequency adequate to assess the above based on the number of subjects enrolled at each site and 
the time from enrollment of the subjects.  The monitor should have access to laboratory test reports 
and other subject records needed to verify the entries on the Case Report Form.  The investigator 
(or his/her designee) agrees to cooperate with the monitor to ensure that any problems detected 
during these monitoring visits are resolved. 
A site visit monitoring report will be prepared for each visit.  Details of clinical site monitoring 
are documented in the Clinical Monitoring Plan (CMP). The CMP describes in detail who will 
conduct the monitoring, at what frequency monitoring will be done, at what level of detail 
monitoring will be performed, and the preparation and distribution of monitoring reports.  
Independent audits may be conducted by auditors from the sponsor or its designee or regulatory 
agencies.

10.1.8. Quality Assurance and Quality Control 
Each clinical site, CRO, and laboratory participating in this study will have SOPs for quality 
management that describe: 
• How data will be evaluated for compliance with the protocol, ethical standards, regulatory 
compliance, and accuracy in relation to source documents.  
• The documents to be reviewed (e.g., eCRFs, clinic notes, product accountability records, 
specimen tracking logs, questionnaires, audio or video recordings), who is responsible, and 
the frequency for reviews.  
• Who will be responsible for addressing QA issues (e.g., correcting procedures that are not 
in compliance with protocol) and QC issues (e.g., correcting errors in data entry).  
• Staff training methods and how such training will be tracked.  
• If applicable, calibration exercises conducted prior to and during the study to train 
examiners and maintain acceptable intra-and inter-examiner agreement.  
QC procedures will be implemented beginning with the data entry system and data QC checks that 
will be run on the database will be generated. Any missing data or data anomalies will be 
communicated to the site(s) for clarification/resolution.  
Following written SOPs, the clinical study monitors will verify that the clinical trial is conducted, 
and data are generated, documented (recorded), and reported in compliance with the protocol, 
GCP, and the applicable regulatory requirements (e.g., Good Laboratory Practices (GLP), Good 
Manufacturing Practices (GMP)).  
The investigational site will provide direct access to all trial related sites, source data/documents, 
and reports for monitoring and auditing by the sponsor, and inspection by local and regulatory 
authorities. 
10.1.9. Data Handling and Record Keeping 
The investigator shall supply the sponsor or its designee on request with any required background 
data from the study documentation or clinic records.  This is particularly important when data on 
the electronic Case Report Forms requires clarification.  In case of special problems/and or 
governmental queries or requests for audit inspections, it is also necessary to have access to the 
complete study records, provided that subject confidentiality is protected.  
All source data forms should be typed or filled out using indelible ink and must be legible.  Errors 
should be crossed out with a single line, but not obliterated, the correction inserted, and the change 
initialed and dated by the investigator or his/her authorized delegate.   
The investigator should understand that source documents for this trial should be made available 
to appropriately qualified personnel from the sponsor or its designees or to health authority 
inspectors after appropriate notification.  The verification of the eCRF Data must be by direct 
inspection of source documents. 


 
 
Page 62 
Protocol BTX.2018.001 Version 2.4 
07-June-2018 
CONFIDENTIAL 
For each subject enrolled, an eCRF must be completed by an authorized delegate from the study 
staff and signed by the principal investigator.  If a subject withdraws from the study, the reason 
must be noted on the eCRF.  If a subject is withdrawn from the study because of a treatment-
limiting adverse event, thorough efforts should be made to clearly document the outcome.  The 
investigator should ensure the accuracy, completeness, and timeliness of the data reported to the 
sponsor in the eCRF’s and in all required reports. 
Each participating site will maintain appropriate medical and research records for this trial, in 
compliance with ICH E6 and regulatory and institutional requirements for the protection of 
confidentiality of subjects.  
Source data are all information, original records of clinical findings, observations, or other 
activities in a clinical trial necessary for the reconstruction and evaluation of the trial.  Examples 
of these original documents and data records include, but are not limited to, hospital records, clinic 
and office charts, laboratory notes, memoranda, subjects’ memory aids or evaluation checklists, 
subject diaries, pharmacy dispensing records, recorded audio tapes of counseling sessions, 
recorded data from automated instruments, copies or transcriptions certified after verification as 
being accurate and complete, microfiches, photographic negatives, microfilm or magnetic media, 
x-rays, and subject files and records kept at the pharmacy, at the laboratories, and medico-technical 
departments involved in the clinical trial.  
Data collection is the responsibility of the clinical trial staff at the site under the supervision of the 
site principal investigator. The investigator is responsible for ensuring the accuracy, completeness, 
legibility, and timeliness of the data reported.  
All source documents should be completed in a neat, legible manner to ensure accurate 
interpretation of data. Black ink is required to ensure clarity of reproduced copies. When making 
changes or corrections, cross out the original entry with a single line, and initial and date the 
change. DO NOT ERASE, OVERWRITE, OR USE CORRECTION FLUID OR TAPE ON THE 
ORIGINAL.  
Source documents will be maintained for recording data for each subject enrolled in the study. 
Data reported in the eCRF derived from source documents should be consistent with the source 
documents or the discrepancies should be explained and captured in a progress note and 
maintained in the subject’s official study record.  
Clinical data (including AEs, concomitant medications, and expected adverse reactions data) and 
clinical laboratory data will be entered into the electronic data capture (EDC) system, a 21 CFR 
Part 11-compliant data capture system provided by the CRO. The data system includes password 
protection and internal quality checks, such as automatic range checks, to identify data that appear 
inconsistent, incomplete, or inaccurate. Clinical data will be entered directly from the source 
documents. 
The investigator must maintain adequate and accurate records to enable the conduct of the study 
to be fully documented and the study data to be subsequently verified.  These documents should 


 
 
Page 63 
Protocol BTX.2018.001 Version 2.4 
07-June-2018 
CONFIDENTIAL 
be classified into two different separate categories (1) Investigator’s Study File, and (2) Subject 
clinical source documents. The Investigator’s Study File will contain the protocol/amendments, 
Case Report and Query Forms, IRB/EC and governmental approval (as appropriate) with 
correspondence, sample informed consent/assent, study drug records, staff curriculum vitae and 
authorization forms and other appropriate documents/correspondence. All records defined in 21 
CFR 312.57 will be kept on file. 
The investigator must keep these two categories of documents on file for at least 2 years after the 
latest of the following: completion, discontinuation of the study, or the regulatory submission for 
which the study is being performed is no longer under review.  After that, the documents may be 
destroyed, subject to local regulations. 
Should the investigator wish to assign the study records to another party or move them to another 
location, the sponsor must be notified in advance. 
If the investigator cannot guarantee this archiving requirement at the investigational site for any or 
all of the documents, special arrangements must be made between the investigator and the sponsor 
to store these in a sealed container(s) off-site so that they can be returned sealed to the investigator 
in case of a regulatory audit.  Where source documents are required for the continued care of the 
subject, appropriate copies should be made for storing outside of the site. 
The investigator shall supply the sponsor on request with any required background data from the 
study documentation or clinic records.  This is particularly important when data on the eCRFs 
requires clarification.  In case of special problems/and or governmental queries or requests for 
audit inspections, it is also necessary to have access to the complete study records, ensuring that 
subject confidentiality is protected. 
10.1.10. 
Protocol Deviations 
A protocol deviation is any noncompliance with the clinical trial protocol, GCP, or other study 
requirements (e.g., SOPs, Laboratory Manuals, etc). The noncompliance may be either on the part 
of the subject, the investigator, or the study site staff.  As a result of deviations, corrective actions 
are to be developed by the site and implemented promptly.  
These practices are consistent with ICH E6:  
• 4.5 Compliance with Protocol, sections 4.5.1, 4.5.2, and 4.5.3  
• 5.1 Quality Assurance and Quality Control, section 5.1.1  
• 5.20 Noncompliance, sections 5.20.1, and 5.20.2.  
It is the responsibility of the site to use continuous vigilance to identify and report deviations within 
5 working days of identification of the protocol deviation, or within 5 working days of the 
scheduled protocol-required activity. All deviations must be addressed in study source documents 
and reported to the clinical study monitor or to the CRO.  Protocol deviations must be sent to the 
IRB/EC per their guidelines. The site investigator/study staff is responsible for knowing and 
adhering to their IRB/EC requirements.

CONFIDENTIAL 
It is not anticipated that waivers of eligibility requirements will be granted for any subjects.  
However, if eligibility requirements are waived in special circumstances, waivers must be 
approved by the medical monitor and the sponsor before a subject may be enrolled.  
Documentation of granted waivers will be maintained in the investigator’s and sponsor’s files. 
10.1.11. 
Publication and Data Sharing Policy 
The results of this study may be published or presented at scientific meetings.  The investigator 
agrees to submit all manuscripts or abstracts to Botanix Pharmaceuticals at least 30 days prior to 
submission.  This allows Botanix Pharmaceuticals to protect proprietary information and to 
provide comments based on information from other studies that may not yet be available to the 
investigator. 
In accordance with standard editorial and ethical practice, Botanix Pharmaceuticals will generally 
support publication of multicenter trials in their entirety.  In this case, a coordinating investigator 
will be designated by mutual agreement.  Authorship will be determined by mutual agreement. 
10.2. 
Conflict of Interest Policy 
The independence of this study from any actual or perceived influence is critical.  Therefore, any 
actual conflict of interest of persons who have a role in the design, conduct, analysis, publication, 
or any aspect of this trial will be disclosed and managed.  Furthermore, persons who have a 
perceived conflict of interest will be required to have such conflicts managed in a way that is 
appropriate to their participation in the study. The study leadership has established policies and 
procedures for all study group members to disclose all conflicts of interest and will establish a 
mechanism for the management of all reported dualities of interest.

2. INTRODUCTION 
Acne is the most common skin disease in the world and is characterized by partial obstruction of 
the pores and associated local skin lesions that can appear on the face, chest or back [1, 2]. 
Obstructed pores can become enlarged and inflamed as sebum and its breakdown products 
accumulate, resulting in visible lesions that can be unsightly and cause permanent scarring [1, 2]. 
Acne usually begins in puberty and affects many adolescents and young adults, but it can occur 
at any stage of life. Approximately 85 percent of people between the ages of 12 and 24 
experience at least minor acne [3]. Acne often causes significant physical and psychological 
problems such as permanent scarring, poor self-image, depression and anxiety [4]. 
Botanix Pharmaceuticals’ BTX 1503 containing the active pharmaceutical ingredient, 
cannabidiol (CBD) in a topical liquid formulation, is being developed for the treatment of acne 
vulgaris. CBD is a member of a broader family of compounds knowns as cannabinoids, a class of 
compounds originally derived from the cannabis sativa plant [5].  
No known well-controlled, human clinical studies have ever been conducted using CBD to treat 
skin disease, and no CDB containing pharmaceuticals have been approved to treat skin disease. 
Researchers have found that CBD may play a beneficial role in regulating the cutaneous 
endocannabinoid system by decreasing unwanted skin cell growth, sebum production and skin 
inflammation associated with many human skin diseases [5].  
BTX 1503 is a formulation of active synthetic CBD and inactive excipients designed to deliver a 
consistent dose of CBD to directly treat patients with acne. It is considered that CBD may: 
• normalize excessive lipid synthesis of human sebocytes; 
• decrease proliferation (but not the viability) of these human sebocytes; 
• inhibit hyperproliferation of keratinocytes; 
• exert anti-inflammatory actions; and  
• have anti-bacterial effects [5, 6].

This study is designed to investigate the efficacy, safety and tolerability of BTX 1503 in subjects 
with moderate to severe acne.  
3. STUDY OBJECTIVES 
The objective of this study is to assess safety and efficacy of various doses of BTX 1503 liquid 
formulation in subjects with moderate to severe acne vulgaris of the face. 
4. STUDY DESIGN 
4.1 
Overall Study Design 
This will be a multi-center, randomized, double-blind, vehicle-controlled, parallel group, dose-
finding study in pediatrics, adolescents, and adults (aged 12 to 40 years). Approximately 360 
subjects will be enrolled.  
There will be five dose groups. All subjects will apply study drug for 84 days. 
• BTX 1503 5% twice daily (BID), 
• BTX 1503 5% once daily (QD), 
• BTX 1503 2.5% once daily (QD), 
• Vehicle BID, or 
• Vehicle QD. 
At the Baseline visit, qualified subjects will be randomized to treatment using an Interactive 
Web-based Randomization System (IWRS).  The study will be a total of up to 17 weeks in 
duration; screening period up to 35 days (5 weeks) and 84 days (12 weeks) of treatment. During 
the study subjects will return to the study clinic at Day 14, 28, 56, and 84 (Study Exit).  
4.1.1 
Schedule of Visits and Assessments 
The schedule of assessments can be found in Section 7.3.8 of the protocol. 
4.1.2 
Method of Assigning Subjects to Treatment Groups 
A randomization schedule will be generated by a member in the QST Consultations, Ltd. (QST) 
Statistical Services department who is not associated with the conduct or analysis of the study, 
using a validated system.  The randomization list will not be stratified, but stratification by site 
will be accomplished within the Interactive Web-based Randomization System (IWRS).

CONFIDENTIAL 
Once a subject is deemed eligible to enroll, randomization will occur using an IWRS. The IWRS 
will assign a study drug kit number based on a predetermined randomization schedule. The kit 
number will be recorded in the electronic case report form (eCRF).  Randomization will be 
2:2:2:1:1 (90 subjects in each active group and 45 in each vehicle group) and done by site.  
4.1.3 
Blinding 
The Sponsor, the CRO, the investigator, study site personnel and subjects will be blinded to the 
treatment assignment.  The randomization schedule will be kept strictly confidential and 
accessible only to authorized persons.  Only when the study has been completed, the protocol 
violations determined, and the study database locked will the randomization schedule be made 
available for analysis. 
During the study, the randomization code will not be broken except in the case of a safety 
concern, either for an individual subject or for the entire study. If a subject has an adverse event 
(AE) that may necessitate unblinding of the randomization code, the site will contact the CRO 
and sponsor to discuss if there are options other than unblinding. If the site and sponsor agree 
that unblinding is in the best interests of the subject, the IWRS system will be used to obtain 
treatment assignment information. The Medical Monitor must be notified whenever study 
medication is unblinded, preferably prior to unblinding a subject. 
5. EFFICACY AND SAFETY ENDPOINTS 
5.1 
Efficacy Endpoints 
For all efficacy evaluations the measurement endpoint is defined at Day 84. 
5.1.1 
Primary Efficacy Endpoint 
The primary efficacy endpoint for the study is: 
• Absolute change from Baseline in inflammatory lesion counts at Day 84. 
5.1.2 
Secondary Efficacy Endpoints 
The secondary efficacy endpoints for the study are: 
• Absolute change from Baseline in non-inflammatory lesion counts at Day 84, 
• The percent change from Baseline in the inflammatory lesion counts at Day 84,

• The proportion of subjects with an IGA score of “clear” or “almost clear” at Day 84, and  
• The proportion of subjects with an IGA score of “clear” or “almost clear” at Day 84 and 
at least a 2-grade reduction from the Baseline IGA score. 
5.1.3 
Exploratory Efficacy Endpoints 
The exploratory efficacy endpoints are: 
• The change from Baseline in the total lesion count at Day 84, 
• The percent change from Baseline in the total lesion count at Day 84, 
• The change from Baseline in the IGA scores at Day 84, 
• The absolute and percent change from Baseline in inflammatory, non-inflammatory, and 
total lesion counts at Day 14, Day 28, and Day 56, 
• The proportion of subjects with an IGA score of “clear” or “almost clear” at Day 14, Day 
28, and Day 56, 
• The proportion of subjects with at least a 2-grade reduction from the Baseline IGA score 
at Day 14, Day 28, and Day 56, 
• The proportion of subjects with an IGA score of “clear” or “almost clear” at Day 14, Day 
28, and Day 56 and at least a 2-grade reduction from the Baseline IGA score, 
• The change from Baseline in the Acne-QoL at Day 84, and 
• Subject’s assessment of the change in their acne from Baseline to Day 84 (Patient 
Reported Outcome [PRO]). 
5.2 
Safety Endpoints 
Safety will be assessed through adverse events (AEs), cutaneous tolerability (erythema, scaling, 
dryness, pruritus, and burning/stinging), complete blood count (CBC), chemistry, and urinalysis 
laboratory testing, and physical exam.

6. STATISTICAL AND ANALYTICAL PLANS 
6.1 
General Methodology 
All statistical processing will be performed using SAS® 9.3 or higher. No interim analyses are 
planned. This Phase 2 study is designed to identify the response to two different dosing 
frequencies and two concentrations of BTX 1503. Statistical tests applied to the outcomes will be 
exploratory. No adjustments for Type I error will occur. 
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, standard deviation (SD), median, minimum and maximum. 
The primary method of handling missing efficacy data in the ITT analysis set will be based on 
last observation carried forward (LOCF). Repeated measures analyses will be used on the 
observed data as a sensitivity analysis on the primary endpoint and the first secondary endpoint.   
The efficacy analysis performed on the ITT population is considered the primary analysis.  The 
efficacy analysis performed on the per-protocol (PP) population is considered supportive 
analysis. 
The number of subjects in each analysis set will be summarized. Reasons for study withdrawal 
during the study will be summarized using frequencies and percentages by treatment group. 
Reported AEs, medical history terms, and prior and concomitant procedures and therapies will 
be classified on the basis of Medical Dictionary for Regulatory Activities (MedDRA) 
terminology.  Prior and concomitant medications will be classified on the basis of World Health 
Organization Drug Dictionary (WHO-DDE) terminology. 
6.1.1 
Statistical Analysis 
All analyses will be performed by QST using SAS® Version 9.3 or later.  All summary tables 
and data listings will be prepared utilizing SAS® software. 
The standard operating procedures (SOPs) of QST will be followed in the creation and quality 
control of all data displays and analyses. 
6.1.2 
Baseline Definition 
Baseline is defined as the last non-missing assessment prior to first application of study drug.

6.1.3 
Visit Windowing 
Data will be summarized based on nominal visit indications with the exception of data captured 
at early termination and unscheduled visits. Data from early termination and unscheduled visits 
will be summarized based on mapped visit values.  The analysis windows for early termination 
and unscheduled visits are presented in the following table.

Data collected at early termination and unscheduled visits prior to study day 9 will not be 
analyzed, with the exception of those identified as baseline values.  Data collected at early 
termination and unscheduled visits after study day 98 will not be included in analyses.   
The definition for the study day included in each study window is defined as below: 
 
Study Day prior to Day 1 = Visit Date – Day 1 Date 
 
Study Day on or after Day 1 = Visit Date – Day 1 Date + 1 
If an assessment’s mapped visit is a visit at which the subject has data from a scheduled visit 
present, or if no analyses are planned for the assessment at the mapped visit, the data collected at 
the early termination or unscheduled visit will not be included in analyses.   
In the event of multiple values from unscheduled or early termination assessments within an 
analysis window, the value closest to the scheduled visit target study day will be used for 
analyses.  If two values tie as closest to the time point (for example, one value is before and the 
other value is after the time point), then the later value will be selected.  
Data collected at all visits will be included in the data listings with visit presented as reported by 
the site. 
6.1.4 
Adjustments for Covariates 
Baseline lesion count will be a covariate for the efficacy endpoints for acne lesion counts. No 
other covariates are planned to be used in the analyses for this study.

CONFIDENTIAL 
6.1.5 
Handling of Dropouts or Missing Data 
All efforts will be made to minimize the occurrence of missing data. It is not expected that 
dropout rates will differ between groups. Therefore, the primary method of handling missing 
efficacy data in the ITT analysis set will be based on last observation carried forward (LOCF). 
Summary of efficacy and pharmacology variables for the PP subjects will be based on available 
data. No imputation will be done for non-efficacy related variables. 
If a partial date is reported where the day is missing, then the day will be imputed as the first day 
of the month unless the month is the same month as the first application of study drug then the 
day will be that of first application with the month and year remaining the same. If a partial date 
is reported where the month is missing, then the month will be imputed to January unless the 
year is the same year as the first application of study drug then the month will be that of first 
application with the year remaining the same. If a partial date where both the day and month is 
missing, follow details as stated previously.  
Missing AE start dates will be imputed using partial date imputation rules as previously 
described in this Section.  
6.1.6 
Interim Analyses and Data Monitoring 
No interim analysis or data monitoring is planned for this study. 
6.1.7 
Multicenter Studies 
This study will be conducted at multiple investigational sites in the United States and Australia 
with the intention of pooling the results for analysis.  
6.1.8 
Multiple Comparisons/Multiplicity 
This Phase 2 study is designed to identify the response to two different concentrations and 
dosing frequencies of BTX 1503. Statistical tests applied to the outcomes will be exploratory for 
establishing the dose and sample size for Phase 3 studies. No adjustments for Type I error will 
occur. 
6.1.9 
Use of an Efficacy Subset of Subjects 
Subjects randomized to study drug who complete the Day 84 visit without noteworthy study 
protocol violations, including compliance with study drug application, Day 84 visit window, and 
completion of efficacy evaluations on Day 84 will form the PP Population.  The noteworthy

CONFIDENTIAL 
protocol violations will be defined at the time of evaluability evaluation, the time between the 
database soft lock and hard lock before unblinding. 
Excluding subjects who have noteworthy protocol violations will decrease the variability in 
treatment response and will allow for a better determination of dose-response relationship of 
BTX 1503. 
6.1.10 
Active-Control Studies Intended to Show Equivalence 
Not applicable to this study.  
6.1.11 
Examination of Subgroups 
Subset analyses will be conducted for the PP analysis set on the primary efficacy endpoint and 
for the secondary endpoints, absolute change from Baseline in non-inflammatory lesion counts at 
Day 84 and subjects with an IGA score of “clear” or “almost clear” at Day 84 and at least a 2-
grade reduction from the Baseline IGA score. These analyses will be summarized using 
descriptive statistics. The specific subsets within the PP analysis set that will be evaluated 
include:  
• Baseline inflammatory lesion count (< median vs ≥ median); 
• Baseline non-inflammatory count (< median vs ≥ median); 
• Baseline total lesion count (< median vs ≥ median and < 80th percentile vs ≥ 80th 
percentile); 
• Baseline IGA (3 (Moderate) vs 4 (Severe)); 
• Baseline Acne-QoL: 
o Self-Perception domain (< median vs ≥ median),  
o Role-Social domain (< median vs ≥ median),  
o Role-Emotional (< median vs ≥ median), and  
o Acne Symptoms (< median vs ≥ median); 
• PRO (Improved (includes responses of much better and slightly better) vs. Same 
(includes response of the same) vs Worsened (includes responses of slightly worse and 
much worse)); 
• Geographical region (US vs AUS);

endpoints, absolute change from Baseline in non-inflammatory lesion counts at Day 84 and 
subjects with an IGA score of “clear” or “almost clear” at Day 84 and at least a 2-grade reduction 
from the Baseline IGA score.  Responders are defined as, 80th percentile showing absolute 
reduction in inflammatory lesions from Baseline. These analyses will be summarized using 
descriptive statistics.  The specific subsets within the responder PP analysis set that will be 
evaluated include: 
• Baseline inflammatory lesion count (< median vs ≥ median); 
• Baseline non-inflammatory count (< median vs ≥ median); 
• Baseline total lesion count (< median vs ≥ median and < 80th percentile vs ≥ 80th 
percentile); 
• Baseline IGA (3 (Moderate) vs 4 (Severe)); 
• Compliance (percent compliance < median vs ≥ median) 
6.2 
Disposition of Subjects 
The number of subjects included in each analysis population (randomized, ITT, safety, PP) will 
be summarized by treatment group.  The number of subjects completed and discontinued 
(including the reasons for discontinuation) will be summarized for each treatment group. 
Subjects who are excluded from an analysis population will be summarized by the reasons for 
exclusion. 
6.3 
Protocol Deviations

Analysis of Efficacy 
The efficacy analyses will be performed using the ITT (primary) and PP (supportive) analysis 
sets. The lesion count and IGA analyses will employ the methods for handling missing data as 
described by Section 6.1.5. Lesion count and IGA data will also be shown in by-subject listings. 
6.8.1 
Primary Efficacy Analysis 
Absolute change from Baseline to Day 84 in inflammatory lesion counts will be analyzed using 
either parametric or non-parametric methods consistent with the statistical assumptions required 
to support the analyses. Specifically, the tests of superiority will be based on an ANCOVA with 
factors of treatment (with the vehicle treatment groups combined) and the respective Baseline 
lesion count as a covariate, or on ranked data submitted to an ANCOVA with factors of 
treatment and the respective Baseline lesion count as a covariate.  
A skewness test, based on the methods presented by J.H. Zar (1984), will be applied to the 
residuals resulting from an ANCOVA. A two-sided p-value for the skewness test significant at 
0.01 will imply the use of the non-parametric method. If a parametric analysis is indicated, the 
results of the parametric analysis will be considered the primary analysis. Should a non-
parametric analysis be indicated, the absolute changes in inflammatory lesions will be rank 
transformed prior to submitting them to the ANCOVA. Results of the rank-transformed analyses 
then will be considered the primary analysis; however, results of the non-ranked transformed 
analyses will also be presented. 
6.8.2 
Secondary Efficacy Analysis 
6.8.2.1 
Lesion Counts 
The absolute change from Baseline in non-inflammatory lesion count at Day 84 will be 
summarized similarly as absolute change from Baseline for inflammatory lesion count (primary 
efficacy endpoint). Percent change from Baseline to Day 84 in inflammatory and non-
inflammatory lesion counts will be analyzed using the same ANCOVA method described for the 
primary endpoint. 
6.8.2.2 
Investigator Global Assessment 
The proportion of subjects with at least a 2-grade reduction from the Baseline IGA score at Day 
84 will be analyzed with logistic regression. Pairwise tests will be conducted comparing the 
treated groups to a combined vehicle. The proportion of subjects with an IGA score of “clear” or 
“almost clear” at Day 84 will be analyzed using the same logistic method as described above.

The IGA will be dichotomized into “success” and “failure”, with a subject considered a 
“success” at each individual visit if the IGA at that visit is Clear (“0”) or Almost Clear (“1”) and 
at least 2 grades less than the Baseline score. The proportion of subjects who are dichotomized to 
success at Day 84 will be analyzed using the same logistic method as described above.  
6.8.3 
Exploratory Efficacy Analysis 
6.8.3.1 
Lesion Counts 
The absolute and percent change from Baseline in the total lesion count at Day 84 will be 
summarized with descriptive statistics.  
Additional comparisons between vehicle BID to BTX 1503 BID and vehicle QD to each BTX 
1503 QD group for the absolute and percent change from Baseline to Day 84 in inflammatory 
and non-inflammatory lesion counts will be analyzed using either parametric or non-parametric 
methods consistent with the approach used for the primary endpoint using an ANCOVA with 
factors of treatment where no treatment groups are combined and the respective Baseline lesion 
count as a covariate or on ranked data submitted to an ANCOVA with factors of treatment where 
no treatment groups are combined and the respective Baseline lesion count as a covariate.  
A further comparison will be made between vehicle QD to a combined BTX 1503 QD group for 
the absolute and percent change from Baseline to Day 84 in inflammatory and non-inflammatory 
lesion counts using an ANCOVA with factors of treatment where the two BTX 1503 QD 
treatment groups are combined and the respective Baseline lesion count as a covariate or on 
ranked data submitted to an ANCOVA with factors of treatment where the two BTX 1503 QD 
treatment groups are combined and the respective Baseline lesion count as a covariate. 
The absolute and percent change from Baseline in inflammatory, non-inflammatory, and total 
lesion counts will be summarized at Day 14, Day 28, and Day 56. The absolute and percent 
change from Baseline in inflammatory, non-inflammatory, and total lesion counts at Day 14, Day 
28, and Day 56 will be analyzed using the same ANCOVA method used for the primary 
endpoint as well as the additional testing described above in this section.  
6.8.3.2 
Investigator Global Assessment 
The dichotomized IGA success at Day 84 will be analyzed with an additional logistic regression 
analysis where no treatment groups are combined. Pairwise tests will be conducted comparing 
the vehicle BID to BTX 1503 BID and comparing the vehicle QD to each BTX 1503 QD group. 
The dichotomized IGA success at Day 84 will additionally be analyzed with a logistic regression

comparing the vehicle QD to BTX 1503 QD combined.  
The change from Baseline in the IGA scores at Day 14, Day 28, Day 56, and Day 84 will be 
summarized with descriptive statistics. The proportion of subjects who are dichotomized to 
success at Day 14, Day 28, and Day 56 will be summarized with proportions. The dichotomized 
success at Day 14, Day 28, and Day 56 will also be analyzed using the same logistic method as 
in the secondary efficacy analysis as well as the additional testing described above in this 
section. 
6.8.3.3 
Acne-QoL 
The change from Baseline in the Acne-QoL domain scores at Day 84 will be summarized with 
descriptive statistics by domain score and treatment group. Domains for the Acne-QoL include 
Self-Perception, Role-Social, Role-Emotional, and Acne Symptoms.  Responses will be coded 
numerically on a scale from 0 (‘extremely’ or ‘extensive’) to 6 (‘not at all’ or ‘none’) within each 
domain.  All questions in each domain will be summed to get the total domain score.  
Self-Perception includes Q1, Q2, Q3, Q6, and Q10; Role-Social includes Q11, Q12, Q13, and 
Q14; Role-Emotional includes Q4, Q5, Q7, Q8, and Q9; and Acne Symptoms includes Q15, 
Q16, Q17, Q18, and Q19 (Martin 2001). 
Domain scores as well as individual question responses will be listed in a by-subject listing. 
6.8.3.4 
Patient Reported Outcome (PRO) 
The PRO will be summarized with counts and percentages by treatment group. 
PRO results will also be shown in a by-subject listing. 
6.9 
Sensitivity Analyses 
A sensitivity analysis will be performed using the ITT population. The primary and the first 
secondary endpoints (change from Baseline in inflammatory and non-inflammatory lesion 
counts) will be analyzed using a repeated measures ANCOVA, with treatment group and visit as 
independent factors and the Baseline value as a covariate.

Safety Evaluation 
6.10.1 
Extent of Exposure 
The extent of exposure to study drug in each treatment group will be summarized by total 
number of days of exposure, total number of applications, number of missed applications, 
number and percentage of subjects who are compliant, average amount of study drug used per 
day (g/day), and amount of drug used total (g). A subject will be considered compliant with the 
dosing regimen if the subject applied 80% to 120% of the expected number of applications while 
enrolled in the study. 
The total amount of study drug used will be calculated from the drug accountability using the 
recorded weights. The difference between the dispensed weight and the returned weight for each 
pump will be summed over all pumps to get the total amount of study drug used. The total 
amount of study drug used will be divided by the total number of exposure days to get the 
average amount of study drug used per day. 
The total number of days of exposure is as follows: 
Date of Last Application – Date of First Application + 1. 
It will be assumed the BID subjects were expected to have 2 applications on the Date of First 
Application. It will also be assumed the BID subjects were expected to have only 1 application 
on the Date of Last Application unless there is evidence to suggest otherwise (i.e. dosing 
deviation log indicates 2 doses were expected). 
The total number of applications taken for BID subjects is as follows: 
2 applications expected on Date of Last Application: 2*(Date of Last Application – Date 
of First Application + 1) – (Number of doses marked as missed on the CRF); 
1 application expected on Date of Last Application: 2*(Date of Last Application – Date 
of First) + 1 – (Number of doses marked as missed on the CRF). 
The total number of applications taken for QD subjects is as follows: 
(Date of Last Application – Date of First Application + 1) – (Number of doses marked as 
missed on the CRF). 
The total number of applications expected for BID subjects is as follows: 
2 applications expected on Date of Last Application: 2*(Date Subject Ended Participation 
– Date of Randomization + 1);

1 application expected on Date of Last Application: 2*(Date Subject Ended Participation 
– Date of Randomization) + 1. 
The total number of applications expected for QD subjects is as follows: 
Date Subject Ended Participation – Date of Randomization + 1.   
If the total number of applications for BID subjects exceeds 178 then it will be set to 178.  
If the total number of applications for QD subjects exceeds 89 then it will be set to 89. 
Compliance will be calculated as a percentage as 100 times the total number of applications 
taken divided by the total number of applications expected while enrolled in the study.    
6.10.2 
Adverse Events 
All AEs that occur during the study will be recorded and classified on the basis of Medical 
Dictionary for Regulatory Activities (MedDRA) terminology. Treatment-emergent AEs 
(TEAEs) are defined as AEs with an onset on or after the date of the first study drug application. 
Adverse events noted prior to the first study drug administration that worsen after Baseline will 
also be reported as AEs and included in the summaries.  
An overall summary of TEAEs will be presented showing the number of subjects reporting at 
least one TEAE, number reporting at least one SAE, number reporting at least one TEAE leading 
to study discontinuation, and number of TEAEs by severity and by relationship for each 
treatment group. The total number of AEs will also be presented as part of the overall summary 
of TEAEs. Treatment-emergent AEs will be summarized by system organ class and preferred 
name. Serious TEAEs, Related TEAEs, Severe TEAEs, and TEAEs leading to study 
discontinuation will also be summarized by system organ class and preferred name.   
In addition, a listing of all AEs, a listing of Serious AEs, and a listing of subjects who 
prematurely discontinue from the study due to an AE will be provided. 
No statistical inference between treatments will be performed on AEs. 
6.10.2.1 
Drug Abuse and Liability Assessments 
Adverse events associated with potential abuse or overdose will be recorded and classified by 
MedDRA System Organ Classifications (SOC) and MedDRA Preferred Terms (PTs) as outlined 
in the Safety Management Plan. The incidence of abuse related AEs will be summarized by 
treatment group using frequency counts and percentages.  
A by-subject listing of abuse related AEs will also be presented.

Clinical Laboratory Evaluation 
Laboratory test results will be summarized with descriptive statistics at Baseline and Day 84. 
Additionally, shifts from Baseline to Day 84 in laboratory test results based on normal ranges 
will be summarized with frequency counts and percentages. Individual laboratory test results as 
well as pregnancy test results will be presented in a by-subject listing.

Other Observations Related to Safety 
6.10.4.1 
Cutaneous Tolerability Assessments 
Cutaneous tolerability (erythema, scaling, dryness, pruritus, and burning/stinging) will be 
summarized at each visit using counts and percentages by treatment group. In addition, worst 
post-Baseline grade will be summarized by treatment group using counts and percentages. Any 
incident of mild, moderate, or severe post-Baseline results will be summarized by treatment 
group using counts and percentages.  
6.10.4.2 
Physical Examination 
Physical examination data will be presented in a by-subject listing.  
7. DETERMINATION OF SAMPLE SIZE 
The sample size for this study is based on clinical considerations only. Subjects will be 
randomized 2:2:2:1:1 with 90 subjects in each active treatment group and 45 subjects in each 
vehicle group for a total 360 subjects. This is considered adequate to evaluate the safety and 
tolerability of BTX 1503 in the treatment of acne vulgaris. 
8. CHANGES IN THE PLANNED ANALYSES 
There are no changes in the conduct of the study or planned analyses.
