1.1 
Synopsis 
Protocol Title: An open-label, multicenter, Phase Ib study of B244 delivered as a topical spray to assess 
safety in pediatric subjects aged 2 to 17 years with atopic dermatitis 
Rationale: 
Clinical studies with topical administration of B244 have been conducted in subjects with acne, 
hypertension, atopic dermatitis, and rosacea. There have been no safety signals observed to date. 
The aim of this study is to assess the safety of B244 in pediatric subjects aged 2 to 17 years with atopic 
dermatitis. 
Objectives and Endpoints 
Objectives 
Endpoints 
Primary 
 
• 
Assessment of the safety and tolerability of B244 
in pediatric subjects with atopic dermatitis. 
• 
Incidence of treatment-emergent adverse events 
(TEAEs).  
• 
Change from Baseline in physical examination at 
each post baseline visit. 
• 
Change from Baseline in vital signs at each 
post baseline visit. 
Exploratory 
 
• 
Efficacy of B244 on signs and symptoms of atopic 
dermatitis. 
 
 
 
 
• 
Efficacy of B244 on patient oriented measure of 
atopic dermatitis. 
 
 
• 
Efficacy of B244 on patient reported assessment of 
atopic dermatitis. 
• 
Changes from Baseline to post baseline visits in: 
- 
Validated Investigator Global Assessment for 
Atopic Dermatitis (vIGA-AD) scale. 
- 
Area Severity Index (EASI) score and each 
component of EASI from Baseline to 
post baseline visits. 
 
• 
Changes is Patient Oriented Eczema Measure 
(POEM total score and each of the 7 components) 
from Baseline to post baseline visits. 
 
• 
Changes in patient reported outcome (self-reported 
ItchMan questionnaire).from Baseline to 
post baseline visits. 
 
Overall Design: 
This is a Phase 1b, open-label, multiple site study assessing twice daily B244 application for 28 days in 
pediatric subjects with atopic dermatitis. 
The study will enroll 36 subjects in 3 cohorts of 12 subjects: 
• 
Cohort 1: subjects aged 2 to 5 years. 
• 
Cohort 2: subjects aged 6 to 11 years. 
• 
Cohort 3: subjects aged 12 to 17 years.

Number of Investigators and Study Centers: 
Approximately 6 Investigators and study centers are expected to participate in this study. 
Number of Subjects: 
The study will enroll 36 subjects in 3 cohorts of 12 subjects: 
• 
Cohort 1: subjects aged 2 to 5 years. 
• 
Cohort 2: subjects aged 6 to 11 years. 
• 
Cohort 3, subjects aged 12 to 17 years. 
Treatment Groups and Duration: 
Subjects will attend for a Screening visit between Days -21 and -14. If all eligibility criteria and none of 
the exclusion criteria are met, subjects will be enrolled into the study and will be required to undergo a 
14 day washout period (Days-14 to -1). Subjects will attend the study center on Day 1(-1 to 1) and the 
Baseline assessments will be performed before application of the first dose. On confirmation of continued 
eligibility the subject and parent or guardian of the subject will be coached on how to apply medication, 
depending on the affected areas. They will be instructed to apply B244 twice daily (approximately 
12 hours apart) for 28 days. The first dose will be applied in the clinic under the supervision of clinical 
staff. Details of dose administration will be recorded in the study diary provided. 
The subjects with their parent or guardian will return to the study center on Days 7, 14, and 21 for 
completion of study assessments. There will be a final study visit on Day 28, this will be defined as the 
end of the study for the subjects. A time window of ±2 day will be permitted for these 4 visits. There will 
not be a period of confinement in the study center all visits will be outpatient visits. 
Safety monitoring will include review of TEAEs, vital signs and physical examination. 
Efficacy will be assessed using EASI, vIGA-AD scale, POEM and ItchMan scores. 
Statistical Methods: 
All subjects who are enrolled and take at least 1 dose of study treatment will be included in the Intent to 
Treat (ITT) population. The ITT population will be the primary population for safety and efficacy 
assessments. 
All subjects in the ITT population without any protocol deviations that may have an impact on the 
efficacy assessments will be included in the Per Protocol (PP) population. The PP population will be the 
supportive population for efficacy assessments. 
The sample size is not based on statistical considerations but is typical for studies of this nature, and is 
considered adequate to characterize the distribution of the planned endpoints. Any statistical testing will 
be considered exploratory and descriptive. 
Data Monitoring Committee: No

1. Urine pregnancy test will be administered to females 11 years of age or older. 
2. Pulse rate, temperature and blood pressure will be obtained. Subject should be allowed to rest for >5 minutes 
sitting, then a single blood pressure and pulse rate measurement will be performed, using the non-dominant arm 
with a calibrated electronic sphygmomanometer. 
3. Patient Oriented Measure questionnaire is to be filled out by the subject or the parent or guardian. 
4. At Baseline, depending on the age of the participant, 1 or 2 bottles will be supplied. Total number of bottles to be 
dispensed to the subjects for the duration of the study will depend upon the body surface area affected by atopic 
dermatitis (Section 6.1). At each visit, study staff will determine each subject’s usage and supply additional 
investigational product if necessary. 
5. The first investigational product application will happen in the study center under clinical staff supervision after 
completion of the baseline assessments. Subjects and parent or guardian will be coached on how to apply the 
study treatment depending on the affected area and will be asked to apply the study treatment twice daily. 
6. Weight of an investigational product kit will be obtained at the at the Baseline visit. Study staff will be asked to 
weigh dispensed bottles PRE FIRST DOSE. Weight will be recorded in grams. Subjects will be asked to bring 
their bottles back for every visit. Upon return for the study visit, bottles will be weighed again.

2.0 INTRODUCTION 
2.1 
Study Rationale 
AOBiome Therapeutics has isolated a purified strain of Nitrosomonas eutropha, designated 
Nitrosomonas eutropha D23, from soil samples. Sequencing of the Nitrosomonas eutropha D23 
genome revealed a distinct genetic profile from that of other published Nitrosomonas strains and 
ammonia (NH3) oxidizing bacteria (AOB) genomes. The unique metabolic and antimicrobial 
activity of Nitrosomonas, in combination with their complete lack of virulence, render these 
bacteria as attractive candidates for topical delivery of nitrite (NO2) and nitric oxide (NO) on 
human skin. This has potential to improve health in both normal and abnormal skin conditions 
(including wound sites). The drug product has been designated the code B244. 
Clinical studies with topical administration of B244 have been conducted in subjects with acne. 
In addition, other clinical studies, either ongoing or completed, have included the investigation of 
the efficacy of B244 in subjects with hypertension, atopic dermatitis, and rosacea. The results of 
these studies have indicated efficacy of B244 with no unexpected safety signals. The aim of this 
study is to assess the safety of B244 in pediatric subjects aged 2 to 17 years with atopic 
dermatitis. 
2.2 
Background 
Ammonia oxidizing bacteria are ubiquitous in the environment and are essential for the initial 
step in nitrification processes, specifically the oxidation of NH3 to NO. They are found in all 
soils and water sources (fresh, ground, and seawater). Nitrosomonas, as AOBs, are 
gram-negative chemolithoautotrophic betaproteobacteria that obtain energy solely from NH3 
oxidation, while fixing carbon dioxide (CO2) for their carbon needs [Arp and Sayavedro-Soto, 
2001]. 
It is hypothesized that there may be regulation of basal NO levels by AOB on the skin. In acne, 
for example, Nitrosomonas eutropha might be expected to down regulate androgen levels. Low 
NO causes high androgen levels. Increasing NO/NO2 by the oxidation of NH3 in sweat by 
Nitrosomonas eutropha may decrease androgen levels. Androgens, the male hormones present in 
men and women, can contribute to acne flares by over stimulating the oil glands and altering the 
development of skin cells that line hair follicles in the skin. Increasing NO/NO2 production may 
therefore have a critical role in controlling the signs and symptoms of acne vulgaris. In this 
regard, the disruption of the normal AOB component of the human microbiome has the potential 
to disrupt the feedback regulation between acne, NO, and androgens. Nitrogen oxide releasing 
drugs or NO donors have also shown activity against Propionibacterium acnes and other 
pathogenic bacteria, anti-inflammatory activity, and inhibition of lipogenesis by 
insulin-stimulated immortal sebocytes (Weller and Price, 2001, Rico et al, 2014).

Other important potential mechanisms through which Nitrosomonas eutropha D23 could 
positively effect acne and other skin diseases include an anti-inflammatory and antimicrobial 
effects 
Clinical studies with topical application of B244 have been conducted, or are planned, include 
studies in subjects with clinical diagnosis of facial acne vulgaris (Investigational New Drug 
[IND] 16487) hypertension (IND 17086), atopic dermatitis (IND 17485) and mild to moderate 
rosacea (IND 18086). Overall, there have been no serious adverse events (SAE) or unexpected 
safety signals observed following treatment with B244. 
Efficacy was supported by statistically significant 2-point reduction in Investigator Global 
Assessment (IGA) with B244 and a trend in the reduction of the number of inflammatory lesions 
compared with vehicle in the study conducted in subjects with facial acne vulgaris (IND16487). 
B244 is comprised of Nitrosomonas eutropha D23 diluted in storage solution (50 mM Na2HPO4 
and 2 mM MgCl2, pH 7.6 ± 0.2). The B244 drug product is provided as a mist formulation in 
sterilized 7.5 or 30 mL plastic containers with appropriate sized and intended use designed spray 
nozzles. There are 3 concentrations, measured by optical density (OD), of the drug product: high 
dose (OD600 4.0 ± 0.8 equivalent to 8 × 109 cells/mL), middle dose (OD600 2.0 ± 0.4 equivalent to 
4 × 109 cells/mL), and low dose (OD600 1.0 ± 0.2 equivalent to 2 × 109 cells/mL). 
A detailed description of the chemistry, pharmacology, efficacy, and safety of B244 is provided 
in the current Investigator’s Brochure. 
2.3 
Benefit/Risk Assessment 
To date, there have been no reported infections or health risks associated with topical application 
or ingestion of Nitrosomonas species. The absence of any known illnesses attributed to these 
bacteria despite widespread human exposure suggests that they are unlikely to pose significant 
health risk. Infection or tissue damage by Nitrosomonas is unlikely, because the sequenced 
genomes of several Nitrosomonas and other AOB lack genes encoding cytotoxins, or other 
known bacterial virulence factors. Further, AOB are slow growing, as compared to most 
heterotrophic bacteria, with optimum doubling times of 8 hours or higher. In particular, 
Nitrosomonas growth is rate limited by the availability of ammonia requiring the oxidation of 27 
moles NH3/mole CO2 fixed. Due to their dependence on ammonia for their growth, the numbers 
of Nitrosomonas on the skin will be necessarily limited and naturally regulated by the amount of 
ammonia produced in sweat. This would ensure that the amount of nitrite and NO generated 
would be relatively low, mitigating the risk of adverse effects due to high NO/NO2 low without 
any adverse effects. 
The Sponsor will immediately notify the Principal Investigator if any additional safety or 
toxicology information becomes available during the study.

4.0 STUDY DESIGN 
4.1 
Overall Design 
This is a Phase 1b, open-label, multiple site study assessing twice daily B244 application for 
28 days in pediatric subjects with atopic dermatitis. 
The study will enroll 36 subjects in 3 cohorts of 12 subjects: 
• Cohort 1: subjects aged 2 to 5 years. 
• Cohort 2: subjects aged 6 to 11 years. 
• Cohort 3: subjects aged 12 to 17 years. 
At Screening and Baseline, all subjects must have confirmed diagnosis of atopic dermatitis, as 
defined by the Hanifin and Rajka criteria, which involves a minimum of 10% but no more than 
60% body surface area and a Validated Investigator Global Assessment for Atopic Dermatitis 
(vIGA-AD) scale of 2 or 3. 
Subjects will attend for a Screening visit between Day -21 and -14. If all eligibility criteria and 
none of the exclusion criteria are met, subjects will be enrolled into the study and will be 
required to undergo a 14 day washout period (Day-14 to -1). The washout period is to ensure the 
subjects do not have any active systemic infections (including but not limited to, ear infections, 
upper respiratory tract infections, throat infections) and that they comply with the withdrawal of 
medications included in Exclusion Criterion 7. On completion of the washout period and 
confirmation of continued eligibility the subjects will be assigned to one of the cohorts based on 
the age of the subject. 
Subjects will attend the study center on Day 1 (-1 to 1) and the Baseline assessments listed in 
Table 1.1 will be conducted. On confirmation of continued eligibility, the subject and parent or 
guardian of the subject will be coached on how to apply medication, depending on the affected 
areas. They will be instructed to apply B244 twice daily (approximately 12 hours apart) for 28 
days and record the details of the application in the study diary provided. They will also be 
provided guidance on the storage of the study treatment. Guidance for the application of B244 is 
provided in Section 6.1. The first dose will be administered on Day 1 in the clinic, under the 
supervision of clinical staff, subsequent doses can be applied outside of the clinic. The 
importance of adherence to the medication schedule will be reinforced at each study visit. 
The subjects with their parent or guardian will return to the study center on Days 7, 14 and 21 
when the assessments listed in Table 1.1 will be conducted. There will be a final study visit on 
Day 28, this will be defined as the end of the study for the subjects. A time window of ±2 day 
will be permitted for these visits. 
Safety monitoring will include review of TEAEs, vital signs and physical examinations as 
indicated in Table 1.1.

Efficacy will be assessed using EASI, vIGA-AD scale, POEM, and ItchMan scores Table 1.1. 
4.2 
Scientific Rationale for Study Design 
AOBiome Therapeutics has developed B244 as a topical application of a natural source of AOB 
and NO/NO2 to the human skin. B244 for topical delivery has the potential to improve health in 
both normal and abnormal skin conditions or wound sites. 
A standard parallel-group, open-label design is used for this study to evaluate the safety and 
tolerability of B244 in pediatric subjects with atopic dermatitis. 
The study will be conducted in pediatric subjects with atopic dermatitis because they are a target 
population. 
The sample size for each cohort is based on the desire to obtain adequate safety and tolerability 
data to achieve the objectives of the study while exposing as few subjects as possible to B244 and 
study procedures. 
This study will be performed in compliance with the protocol, the ICH GCP, GMP, and 
applicable regulatory requirements. 
4.3 
Justification for Dose 
There are 3 concentrations of the drug product available: high dose (OD600 4.0 ± 0.8 equivalent 
to 8 × 109 cells/mL), middle dose (OD600 2.0 ± 0.4 equivalent to 4 × 109 cells/mL) and low dose 
(OD600 1.0 ± 0.2 equivalent to 2 × 109 cells/mL). 
The middle dose has been selected for this study to minimize the exposure while ensuring 
administration of a dose considered likely to show improvement in symptoms of atopic 
dermatitis. 
4.4 
End of Study Definition 
The end of the study is defined as the date of last scheduled procedure shown in the Table 1.1 for 
the last subject in the study. 
4.5 
Dose Escalation Criteria 
There will not be any dose escalation in this study. 
4.6 
Study Stopping Criteria 
Dosing for any individual subject will be stopped if: 
• The subject experiences a possibly drug-related SAE. 
• The subject experiences a possibly drug-related significant non-serious adverse event (AE), 
which in the opinion of the Principal Investigator, Chief Investigator, Medical Monitor, or

Sponsor’s medical representative, warrants discontinuation from the study for that subject’s 
wellbeing. The occurrence of significant non-serious AEs as described above will require 
that further dosing of other subjects be evaluated by the Chief Investigator, the Medical 
Monitor and the Sponsor’s Medical Advisor to determine study discontinuation. 
• The subject’s atopic dermatitis worsens and requires alternative or supplemental medication 
during the study (see Section 6.8 for allowed treatments). 
• The subject or his/her parent or guardian choose to discontinue for any reason. 
Dosing for a cohort will be stopped if: 
• A subject experiences a possibly drug-related SAE. 
• More than 2 subjects experiences a possibly drug-related significant non-serious AE, which 
in the opinion of the Principal Investigator, Chief Investigator, Medical Monitor, or 
Sponsor’s medical representative, warrants discontinuation from the study for that subject’s 
wellbeing. The occurrence of significant non-serious AEs as described above will require 
that further dosing of other subjects be evaluated by the Chief Investigator, the Medical 
Monitor and the Sponsor’s Medical Advisor to determine study discontinuation. 
The study will be stopped if: 
• More than 1 subject experiences a drug-related SAE.

At Baseline visit (Day1), all subjects will be dispensed up to 2 bottles of IP, depending on the 
number of lesions. Upon examining the subject, study staff will instruct the patient on the 
number of pumps to be applied per application for the duration of the treatment.  If during the 
study participation subject develops new lesions, those should be treated as well.  
It is suggested that subjects will use up to the number of bottles indicated in Table 6.1 during 
participation in the trial, however this number should not exceed 6 bottles per subject per study. 
Study staff should monitor usage at every study visit and determine whether more IP should be 
dispensed to the subject based on age and usage, where the total number of pumps per 
application should not exceed 16.  
Subjects and their guardians should use the details in Table 6.2 to guide the suggested number of 
pumps to be applied on each application. Subjects will apply 1 pump (0.14 mL) of B244 (OD600 
2.0 ± 0.4 equivalent to 4 × 109 cells/mL) per 200 cm2 (approximately one adult palm size) of the 
affected area, twice a day approximately 12 hours apart, for 28 days (Day 1 to 28). 
One pump should cover the surface area of skin the approximate size of one adult sized palm. 
One pump will be applied directly to the skin for each atopic dermatitis area that is the size of a 
palm of 1 adult sized hand.

The total number of bottles to be dispensed to the subjects will depend upon the body surface 
area affected by atopic dermatitis (Appendix 6), age of the subject and the number of areas 
affected by the disease. 
The subject and parent or guardian of each subject will be instructed by clinical staff regarding 
the use of the spray pump and application of the dose to the area of atopic dermatitis. The first 
dose will be applied by the subject, parent or guardian in the study center under the supervision 
of the clinical staff. 
For each dosing period, the subject under the supervision of the parent or guardian, or the parent 
or guardian, will dispense the required amount of study treatment using the pump. Whether the 
subject is likely to be able to apply the study treatment will be decided by the Investigator, or 
delegate, during the training session. If the subject is considered to be too young, or would be 
unreliable, to apply the study treatment the application will be done by the parent or guardian. 
Whenever the study treatment is applied by the subject the application must be under the 
supervision of the parent or guardian. 
• The person applying the study treatment should wash his/her hands before and after applying 
study treatment. 
• Subject should shake the bottle before each application and then saturate the application area 
well, holding the bottle approximately 6 inches away from the skin. 
• Subjects will be asked to let the product air dry. 
• Subjects may not wash for 2 hours post morning application of the IP. 
• It is recommended that subjects may not bathe, shower or wash until the morning after the 
evening application of B244. For younger subjects who need cleaning related to diaper 
changes this is acceptable. 
• While in use, one spray bottle may be stored at ambient temperature. 
• DO NOT FREEZE 
• The Sponsor will provide a biome friendly, preservative-free moisturizer and cleanser to be 
used as needed, at the discretion of the parent or guardian to clean the area of application 
before application of the treatment. 
• The subject or parent or guardian will apply the study treatment to the affected area twice 
daily (approximately 12 hours apart) for 28 consecutive days. 
• The parent or guardian will verify if the study treatment was applied as directed. Application 
details will be recorded in the study diary provided. 
• Subjects will be asked not to expose the treatment kit to conditions which are unnatural or 
harmful to the product, such as excessive heat (temperatures over 77°F [25°C] and freezing 
temperatures [at 0°C]). Subjects may travel with their study medication but should not leave 
it in the hot car, outside in the cold temperatures etc. Subjects will also be asked not to 
tamper or cause damage to IP bottle.

Preparation/Handling/Storage 
All investigational drug supplies in the study will be stored in a secure, refrigerated (2 to 8°C) 
safe place, under the responsibility of the Investigator or other authorized individual. 
The Investigator, or designee will maintain temperature monitoring of the IP with daily 
temperature readings. All temperature excursions must be reported to the Sponsor using the 
Temperature Excursion log. If the IP was exposed to the temperature excursion outside the range 
of 2 to 8°C, but for the period greater than 24 hours, the IP must be quarantined until the 
Sponsor’s approval on future use. 
The Investigator or designee must confirm appropriate temperature conditions have been 
maintained during transit for all study treatment received and any discrepancies are reported and 
resolved before use of the study treatment. 
The Investigator or designee must provide instruction to the subject, and parent or guardian, on 
the storage requirements for the study treatment. 
Only subjects enrolled in the study may receive study treatment and only authorized study center 
staff may supply study treatment. All study treatments must be stored in a secure, 
environmentally controlled, and monitored (manual or automated) area in accordance with the 
labeled storage conditions with access limited to the Investigator and authorized study center 
staff. 
The Investigator, institution, or the head of the medical institution (where applicable) is 
responsible for study treatment accountability, reconciliation, and record maintenance (ie, 
receipt, reconciliation, and final disposition records). 
Further guidance and information for the final disposition of unused study treatment will be 
provided. 
6.3 
Accountability, Destruction and Return of Study Supplies 
In accordance with federal and local regulatory requirements, the Investigator and designated site 
personnel must document the amount of IP dispensed to study subjects, the amount returned by 
study subjects, and amount received and returned to the Sponsor, when applicable. Product 
accountability records must be maintained throughout the course of the trial. Any quality issue 
noticed with the receipt or use of an IP (deficient IP in condition, appearance, pertaining 
documentation, labeling, expiry date, etc.) should be promptly reported to the Sponsor, who will 
initiate a complaint procedure. 
All IP must be stored in a secure locked room with access limited to the Investigator and 
designated site personnel. Study product is to be stored in a refrigerator between 2 to 8°C. 
Maintenance of a temperature log is required.

Under no circumstances will the Investigator or designees allow IP to be used other than as 
directed by this Clinical Study Protocol, or dispose of investigational product without Sponsor 
direction. 
The Sponsor will supply sufficient quantities of the IP for the completion of this study. 
The study pharmacist or designated study personnel will maintain an Investigational Materials 
Accountability Record and a Subject IP Accountability Log itemizing all IP received, dispensed 
to and returned from each subject during the study. All dispensed bottles must be accounted for, 
and any discrepancies explained. Study site should contact site Clinical Research Associate 
(CRA) or designee in case of any dispensing errors or if discrepancies are discovered. 
Prior to site closure and at appropriate intervals during the study, site CRA will perform IP 
accountability and reconciliation. At the end of the study, the Investigator or designee will retain 
all the original documentation regarding IP accountability, return, and copies will be sent to the 
Sponsor. 
All unused and used IP tubes will be returned to the Sponsor or its designee for destruction at the 
end of the study. 
6.4 
Measures to Minimize Bias: Randomization and Blinding 
Not applicable, this is an open-label study. 
6.5 
Study Treatment Compliance 
The prescribed dosage, timing, and mode of administration may not be changed. Any departures 
from the intended regimen must be recorded in the electronic case report forms (CRFs). 
At each visit, prior to dispensing study treatment, previously dispensed study treatment will be 
retrieved by the Investigator or designee and compliance assessed. Subjects exhibiting poor 
compliance as assessed by the returned IP and the study diary should be counseled on the 
importance of good compliance to the study dosing regimen. 
6.5.1 
Study Diary Compliance Review 
The subject will be given a study diary at each study visit of the treatment period to record date 
and time of applications, any adverse events, and quality of life assessments. Subjects will record 
every application during the treatment period and will bring the subject diary to each of the 
post baseline study visits for compliance review. The Investigator or designee will verify that the 
subject complied with the application requirements and will file the completed subject diary in 
the study files at each study visit until the Final/Early Termination visit. Any missed application 
notations will be clarified with the subject and documented in the subject’s CRF.

6.5.2 
Treatment Compliance 
Each site participating in the trial will be instructed to assess subject’s compliance by weighing 
the IP and obtaining the weight of the bottles in grams pre- and post-application. Study personnel 
will be asked to weigh dispensed bottle(s) and record the weight pre first application. At each 
subsequent visit and then Day 28 visit, study personnel will need to weigh bottle(s) and record 
the weight. This procedure should be followed every time study medication is dispensed and 
returned. Sites will be provided scales, which will be tared prior to each use. Study personnel 
will be instructed to record measurements into the eCRF. 
6.6 
Concomitant Therapy 
Any medication or vaccine (including over-the-counter or prescription medicines, vitamins, 
and/or herbal supplements) that the subject is receiving within 30 days prior to the start of the IP 
and through the final study visit will be recorded on the appropriate CRF) along with: 
• Reason for use. 
• Dates of administration including start and end dates. 
• Dosage information including dose and frequency. 
Any medications started during the study (including “as needed” medications) will be recorded 
in the concomitant medication list as soon as the Investigational Site will become aware of the 
medication being added. 
The subject, or parent or guardian, will be instructed to record the details of any medication 
taken by the subject outside of the study center in the study diary provided. The details will be 
reviewed by the Investigator or designee on each study center visit. 
The Medical Monitor should be contacted if there are any questions regarding concomitant or 
prior therapy. 
A list of excluded medications/therapy is provided in Appendix 4. 
Previous treatment of atopic dermatitis must be recorded irrespectively of the term it was given. 
Acetaminophen, at doses approved for the age of the subject, is permitted for use any time during 
the study. Other concomitant medication may be considered on a case-by-case basis by the 
Investigator in consultation with the Medical Monitor. 
6.7 
Dose Modification 
The study treatment will be administered as described in this protocol. Up to 16 pumps per 
application may be administered, depending on the number of lesions subject has. Number of 
applications will be documented in each subject’s chart. Any AEs or circumstances that impact 
the dosing of the IP will be documented and reported to the Medical Monitor.

6.8 
Rescue Medication Permitted During the Study 
Over the course of the study, the Investigator will monitor and evaluate subject’s condition and 
determine whether rescue therapy may be necessary. The use of medications to treat a subject’s 
atopic dermatitis during the study will be permitted if the parent, guardian or medical 
professional determines that it becomes medically necessary. Such rescue treatment should not 
exceed 7 days. If a subject requires treatment for more than 7 days or requires systemic therapy, 
they should be discontinued from the study. Medications permitted are listed in Table 6.3. 
Study staff must be notified of the use of any medication as soon as feasible. The details of the 
medication should be recorded in the study diary and transferred to the CRF. Details recorded 
should include medication name, date of administration, dosage, and number of applications.

7.0 DISCONTINUATION OF STUDY TREATMENT AND 
SUBJECT DISCONTINUATION/WITHDRAWAL 
7.1 
Discontinuation of Study Treatment 
The stopping criteria for the study are described in Section 4.6. 
If a subject who does not meet enrollment criteria is inadvertently enrolled, that subject must be 
discontinued from study treatment and the Sponsor or Sponsor designee must be contacted. An 
exception may be granted in rare circumstances for which there is a compelling safety reason to 
allow the subject to continue. In these rare cases, the Investigator must obtain documented 
approval from the Sponsor or Sponsor designee to allow the subject to continue in the study. 
Subjects who discontinue study treatment will not be replaced. 
7.2 
Subject Discontinuation/Withdrawal from the Study 
• A subject may withdraw from the study at any time at his/her own request, or at the request 
of their parent or guardian, or may be withdrawn at any time at the discretion of the 
Investigator for safety, behavioral, compliance, or administrative reasons. 
• If the subject, or their parent or guardian, withdraws consent for disclosure of future 
information, the Sponsor may retain and continue to use any data collected before such a 
withdrawal of consent. 
• If a subject withdraws from the study, he/she or their parent or guardian, may request 
destruction of any samples taken and not tested, and the Investigator must document this in 
the study center study records. 
• See the schedule of assessments (SoA) Table 1.1 for data to be collected at the time of study 
discontinuation and follow-up and for any further evaluations that need to be completed. 
Should a subject, or their parent or guardian request or decide to withdraw from the study, all 
efforts must be made to complete and report the observations as thoroughly as possible up to 
the date of withdrawal. Subjects withdrawing due to an AE should be followed up according 
to the follow-up visit. 
7.3 
Lost to Follow-up 
A subject will be considered lost to follow-up if he or she repeatedly fails to return for scheduled 
visits and is unable to be contacted by the study center. 
The following actions must be taken if a subject fails to return to the study center for a required 
study visit: 
• The study center must attempt to contact the subject or their parent or guardian, and 
reschedule the missed visit as soon as possible and counsel the subject on the importance of 

CONFIDENTIAL 
Protocol ADB244-002 – Amendment 1 
Confidential| ADB244-002| Amendmen1| Date:  25 FEB 2019 
34 
maintaining the assigned visit schedule and ascertain whether or not the subject wishes to 
and/or should continue in the study. 
• Before a subject is deemed lost to follow-up, the Investigator or designee must make every 
effort to regain contact with the subject, or their parent or guardian (where possible, 
3 telephone calls and, if necessary, a certified letter to the subject’s last known mailing 
address or local equivalent methods). These contact attempts should be documented in the 
subject’s CRF. 
• Should the subject continue to be unreachable, he/she will be considered to have withdrawn 
from the study. 
Discontinuation of specific study centers or of the study as a whole are handled as part of 
Appendix 2.

9.0 METHODS OF ASSESSMENT 
9.1 
Subject Demographics 
Basic demographic information, including date of birth, gender, ethnicity, and race will be 
recorded at the Screening Visit. 
9.2 
Concomitant Medication Recording 
All medications (both prescription and nonprescription, and including vitamins, herbals, topicals, 
inhaled, and intranasal) taken within 30 days prior to the start of the IP and through the final study 
visit will be recorded on the appropriate CRF (using their generic and brand name, if known) with 
the corresponding indication, start and stop dates. At each study visit, subjects will be asked 
whether they have started or discontinued any medication since their previous study visit. This 
includes single use or PRN (as needed) medication use. 
Previous treatment of atopic dermatitis must be recorded irrespectively of the term it was given. 
Corresponding condition shall be captured in the subject’s medical history. 
9.3 
Efficacy Assessments 
Planned timepoints for all efficacy assessments are provided in the SoA (Table 1.1). 
The Investigator or designee will be responsible for providing the subjects and parent or guardian 
with an explanation of the purpose of the POEM and Itch assessments and training for the 
completion of the assessments. The Investigator or designee will provide the relevant documents 
for completion and assessments will be completed during visits to the clinic. 
9.3.1 
Validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD) 
Scale 
The Investigator or designee will select the vIGA-AD scale that best describes the overall 
appearance of the atopic dermatitis lesions at each of the assessment timepoints during the study. 
The vIGA-AD scale allows for an assessment of overall disease severity at a specified timepoint, 
based on a 5 point scale. The vIGA-AD scale evaluates clinical characteristics of erythema, 
infiltration, papulation, oozing, and crusting as a guideline for the overall severity assessment 
(Table 9.1).

9.3.2 
Atopic Dermatitis Eczema Area Severity Index 
The EASI is a validated scoring system used to grade the physical signs of atopic dermatitis and 
eczema. The Investigator or designee will select the appropriate score at each of the assessment 
timepoints during the study. 
The EASI evaluation assesses the extent of disease (% involvement) at 4 body sites: 
• Head and neck. 
• Trunk. 
• Upper extremities. 
• Lower extremities. 
and measures 4 clinical signs: 
• Erythema. 
• Edema/papulation. 
• Excoriation. 
• Lichenification. 
graded on a severity scale of 0 to 3 (half points may be used): 
• 0 = None. 
• 1 = Mild. 
• 2 = Moderate. 
• 3 = Severe. 

CONFIDENTIAL 
Protocol ADB244-002 – Amendment 1

41 
Scoring information for each of the above measures will be recorded on paper. 
9.3.3 
Patient Oriented Eczema Measure 
The POEM is a tool developed by the University of Nottingham, United Kingdom, for 
monitoring atopic dermatitis severity. The subject or the parent or guardian of the subject, will 
complete the questionnaire at each of the assessment timepoints. 
Each of the 7 questions in the POEM questionnaire carries equal weight and is scored from 
0 to 4: 
• No days = 0. 
• 1 to 2 days = 1. 
• 3 to 4 days = 2. 
• 5 to 6 days = 3. 
• Every day = 4. 
Scores are then added to yield a total score of 0 to 28; higher scores mean the greater the severity 
of atopic dermatitis. 
9.3.4 
ItchMan Questionnaire 
The ItchMan Questionnaire will be used for the subject, or the parent or guardian, to indicate 
how itchy the area of atopic dermatitis feels at the timepoints during the study. Pictures to guide 
in the grading will be included in the subject diary. 
• 0 = Comfortable, no itch. 
• 1 = Itches a little; does not interfere with activity. 
• 2 = Itches more; sometimes interferes with activity. 
• 3 = Itches a lot difficult to sit still, concentrate. 
• 4 = Itches most terribly; impossible to sit still, concentrate. 
9.3.5 
Application Site Assessment 
The study treatment application sites will be evaluated at each visit, preferably by the same 
assessor. The first investigational product application will happen in the study center under 
clinical staff supervision, after the completion of the baseline assessments.  All subsequent study 
application will be administered by the parent/guardian or by the subject in the setting of 
subject’s home. Skin irritation will be recorded as an adverse event and followed until resolution 
(or stabilization, as applicable) 
9.4 
Safety Assessments

9.4.1 
Physical Examinations 
A complete physical examination will include, at a minimum, assessments of the cardiovascular, 
respiratory, and gastrointestinal systems. Height and weight will also be measured and recorded. 
9.4.2 
Pregnancy Test 
Female subjects aged ≥11 years old, or female patients <11 years old who have started 
menstruating, will have urinary pregnancy test performed at all visits.  The Baseline result must 
be available and must be negative before the subject apply the first application of IP.  Positive 
pregnancy test will disqualify the subject from the participation in the study. 
 
9.4.3 
Medical History 
A complete medical history included evaluation (past or present) of the following: general, head 
and neck, eyes, ears, nose throat, chest/respiratory, heart/cardiovascular, gastrointestinal/liver, 
gynecological/urogenital, musculoskeletal/extremities, skin, neurological/psychiatric, 
endocrine/metabolic, hematologic/lymphatic, allergies/drug sensitivities, past surgeries, 
substance abuse, or any other diseases or disorders. 
The details of the subject’s atopic dermatitis history will be recorded. 
9.4.4 
Vital Signs 
• Blood pressure, pulse and body temperature measurements will be assessed in the sitting 
position with a completely automated device. Manual techniques will be used only if an 
automated device is not available or the subject is uncomfortable or distressed with the use of 
an automated device. 
• Blood pressure and pulse measurements should be preceded by at least 5 minutes of rest for 
the subject in a quiet setting without distractions (eg, television, cell phones, use of electronic 
games). 
• Vital signs will consist of single measurement. 
• Body weight and height will be measured at Screening and at Day 28/Final Visit (or at Early 
Termination Visit, as applicable). 
9.5 
Adverse Events 
The definitions of an AE or SAE can be found in Appendix 3. 
Adverse events will be reported by the subject, parent or guardian. 
The Investigator and any designees are responsible for detecting, documenting, and recording 
events that meet the definition of an AE or SAE and remain responsible for following up AEs 
that are serious, considered related to the study treatment or study procedures, or that caused the 
subject to discontinue the study (see Section 7.0).

9.5.1 
Time Period and Frequency for Collecting AE and SAE Information 
All SAEs will be collected from the signing of the informed consent form (ICF) until the final 
visit (or Early Termination Visit), at the timepoints specified in the SoA (Table 1.1). 
All AEs will be collected from the signing of the ICF until the final visit (or Early Termination 
Visit), at the timepoints specified in the SoA (Table 1.1). 
All SAEs will be recorded and reported to the Sponsor or designee within 24 hours, as indicated 
in Appendix 3. The Investigator or designee will submit any updated SAE data to the Sponsor 
within 24 hours of it being available. 
Investigators or designees are not obligated to actively seek AE or SAE after conclusion of the 
study participation. However, if the Investigator or designee learns of any SAE, including a 
death, at any time after a subject has been discharged from the study, and he/she considers the 
event to be reasonably related to the study treatment or study participation, the Investigator or 
designee must promptly notify the Sponsor. 
The method of recording, evaluating, and assessing causality of AEs and SAEs and the 
procedures for completing and transmitting SAE reports are provided in Appendix 3. 
9.5.2 
Method of Detecting AEs and SAEs 
Care will be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended and 
non-leading verbal questioning of the subject is the preferred method to inquire about 
AE occurrences. 
9.5.3 
Follow-up of AEs and SAEs 
After the initial AE/SAE report, the Investigator or designee is required to proactively follow 
each subject at subsequent visits/contacts. All SAEs, will be followed until resolution, 
stabilization, the event is otherwise explained, or the subject is lost to follow-up (as defined in 
Section 7.3). Further information on follow-up procedures is given in Appendix 3. 
9.5.4 
Regulatory Reporting Requirements for SAEs 
• Prompt notification by the Investigator or designee to the Sponsor of an SAE is essential so 
that legal obligations and ethical responsibilities toward the safety of subjects and the safety 
of a study treatment under clinical investigation are met. 
• The Sponsor has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a study treatment under clinical investigation. The 
Sponsor will comply with country-specific regulatory requirements relating to safety 
reporting to the regulatory authority, IRBs, and Investigators. 

CONFIDENTIAL 
Protocol ADB244-002 – Amendment 1 
Confidential| ADB244-002| Amendmen1| Date:  25 FEB 2019 
44 
• Investigator safety reports must be prepared for suspected unexpected serious adverse 
reactions (SUSARs) according to local regulatory requirements and Sponsor policy and 
forwarded to Investigators as necessary. 
• An Investigator who receives an Investigator safety report describing an SAE or other 
specific safety information (eg, summary or listing of SAEs) from the Sponsor will review 
and then file it along with the Investigator’s Brochure and will notify the IRB, if appropriate 
according to local requirements. 
9.5.5 
Pregnancy 
• Details of all pregnancies in female subjects will be collected after the start of study 
treatment and until 1 month after the last dose. 
• If a pregnancy is reported, the Investigator should inform the Sponsor within 24 hours of 
learning of the pregnancy and should follow the procedures outlined in Appendix 6. 
• Abnormal pregnancy outcomes (eg, spontaneous abortion, fetal death, stillbirth, congenital 
anomalies, and ectopic pregnancy) are considered SAEs. 
9.6 
Treatment of Overdose 
The Sponsor does not recommend specific treatment for an overdose. Washing with 
conventional cleanser and water will remove the product.

10.0 STATISTICAL CONSIDERATIONS 
10.1 Statistical Hypotheses 
No formal statistical hypothesis testing is planned for this study. All analyses will be considered 
exploratory and descriptive. 
10.2 Sample Size Determination 
The study will enroll and dose 36 subjects, in 3 age cohorts of 12 subjects: 
• Cohort 1: subjects aged 2 to 5 years old. 
• Cohort 2: subjects aged 6 to 11 years old. 
• Cohort 3: subjects aged 12 to 17 years old. 
The sample size is not based on statistical considerations but is typical for studies of this nature, 
and is considered adequate to characterize the distribution of the planned endpoints. Any 
statistical testing will be considered exploratory and descriptive. 
10.3 Populations for Analyses 
For purposes of analysis, the analysis sets in Table 10.1 are defined. 
Table 10.1 
Analysis Sets 
Analysis Set 
Description 
Intent to Treat (ITT) population 
All subjects who are enrolled and take at least 1 dose of study treatment. The 
ITT population will be the primary population for safety and efficacy 
assessments. 
Per Protocol (PP) population 
All subjects in the ITT population without any protocol deviations that may 
have an impact on the efficacy assessments. The PP population will be the 
supportive population for efficacy assessments. 
10.4 Statistical Analyses 
The Statistical Analysis Plan will be developed and finalized before database lock and will 
describe the subject analysis sets to be included in the analyses, and procedures for accounting 
for missing, unused, and spurious data. This section is a summary of the planned statistical 
analyses of the primary and secondary endpoints.

All analyses, summaries, and listings will be performed using SAS® software (version 9.3 or 
higher). 
The following descriptive statistics will be used as applicable to summarize the study data unless 
otherwise specified: 
• Continuous variables: sample size (n), mean, standard deviation, median, minimum (min), 
and maximum (max). 
• Categorical variables: frequencies and percentages. 
Individual subject data will be presented in listings. 
10.4.1 
Efficacy Analyses 
All efficacy analyses will be performed on the ITT and PP populations, for overall and by age 
cohorts (2 to 5 years, 6 to 11 years, and 12 to 17 years). 
Summary statistics will be provided for the vIGA-AD scale, EASI score (total and by 
component), POEM score (total and by component) and the ItchMan scale, and changes from 
baseline at each visit. The frequency and percentage of subjects who have achieved clear (0) or 
almost clear (1) on the vIGA-AD scale will also be provided at each visit. 
10.4.2 
Safety Analyses 
All safety analyses will be performed on the ITT population. 
All safety assessments, including TEAEs, vital signs and weight, physical examinations, medical 
examination pregnancy test results and concomitant medication will be listed and as appropriate 
summarized with descriptive statistics. 
Treatment-emergent adverse events are defined as AEs that first occurred or worsened in 
severity after the first administration of study treatment. 
Adverse events will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA). The numbers of TEAEs and incidence rates will be tabulated by preferred term and 
system organ class, for overall and by cohort. 
Treatment-emergent AEs by maximum severity, TEAEs by relationship to study treatment, 
SAEs, TEAEs leading to death, and TEAEs leading to discontinuation of study treatment will be 
tabulated for overall and by age cohort. 
All vital signs measurements, weight, and body mass index will be summarized for overall and 
by age cohort, using descriptive statistics at each visit for raw numbers and change from 
Baseline. The incidence of abnormal physical examination results will also be summarized using 
descriptive statistics.

source data should be traceable, should not obscure the original entry, and should be explained if 
necessary (eg, via an audit trail). 
• Source documents provide evidence for the existence of the subject and substantiate the 
integrity of the data collected. Source documents are filed at the Investigator’s study center. 
• Data reported on the CRF or entered in the CRF that are transcribed from source documents 
must be consistent with the source documents or the discrepancies must be explained. The 
Investigator may need to request previous medical records or transfer records, depending on 
the study. Also, current medical records must be available. 
• Source documents will include, but are not limited to, screening logs, questionnaires and 
forms completed by the clinical staff and the subjects, or their parent or guardian. 
Study and Study Center Closure 
The Sponsor designee reserves the right to close the study center or terminate the study at any 
time for any reason at the sole discretion of the Sponsor. Study centers will be closed upon study 
completion. A study center is considered closed when all required documents and study supplies 
have been collected and a study center closure visit has been performed. 
The Investigator may initiate study center closure at any time, provided there is reasonable cause 
and sufficient notice is given in advance of the intended termination. 
Reasons for the early closure of a study center by the Sponsor or Investigator may include but 
are not limited to: 
• Failure of the Investigator to comply with the protocol, the requirements of the IRB or local 
health authorities, the Sponsor’s procedures, or GCP guidelines. 
• Inadequate recruitment of subjects by the Investigator.

Appendix 3 
Adverse Events: Definitions and Procedures for Recording, 
Evaluating, Follow-up, and Reporting 
Definition of AE 
AE Definition 
• 
An AE is any untoward medical occurrence in a patient or subject, temporally associated with the use 
of study treatment, whether or not considered related to the study treatment. 
• 
NOTE: An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of 
study treatment. 
 
Events Meeting the AE Definition  
• 
Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or other safety 
assessments (eg, electrocardiogram, radiological scans, and vital signs measurements), including those 
that worsen from Baseline, considered clinically significant in the medical and scientific judgment of 
the Investigator (ie, not related to progression of underlying disease). 
• 
Exacerbation of a chronic or intermittent pre-existing condition including either an increase in 
frequency and/or intensity of the condition. 
• 
New conditions detected or diagnosed after study treatment administration even though it may have 
been present before the start of the study. 
• 
Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction. 
• 
Signs, symptoms, or the clinical sequelae of a suspected overdose of either study treatment or a 
concomitant medication. Overdose per se will not be reported as an AE/SAE unless it is an intentional 
overdose taken with possible suicidal/self-harming intent. Such overdoses should be reported 
regardless of sequelae. 
 
Events NOT Meeting the AE Definition  
• 
Any clinically significant abnormal laboratory findings or other abnormal safety assessments which are 
associated with the underlying disease, unless judged by the Investigator to be more severe than 
expected for the subject’s condition. 
• 
The disease/disorder being studied or expected progression, signs, or symptoms of the disease/disorder 
being studied, unless more severe than expected for the subject’s condition. 
• 
Medical or surgical procedure (eg, endoscopy, and appendectomy): the condition that leads to the 
procedure is the AE. 
• 
Situations in which an untoward medical occurrence did not occur (social and/or convenience 
admission to a hospital). 
• 
Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present or detected at the 
start of the study that do not worsen.

Protocol ADB244-002 – Amendment 1 
Confidential| ADB244-002| Amendmen1| Date:  25 FEB 2019 
56 
Definition of SAE 
If an event is not an AE per definition above, then it cannot be an SAE even if serious conditions 
are met (eg, hospitalization for signs/symptoms of the disease under study, death due to 
progression of disease). 
An SAE is defined as any untoward medical occurrence that, at any dose: 
a) Results in death. 
b) Is life-threatening 
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. 
c) Requires inpatient hospitalization or prolongation of existing hospitalization 
In general, hospitalization signifies that the subject has been detained (usually involving at least an 
overnight stay) at the hospital or emergency ward for observation and/or treatment that would not have 
been appropriate in the physician’s office or outpatient setting. Complications that occur during 
hospitalization are AEs. If a complication prolongs hospitalization or fulfills any other serious criteria, the 
event is serious. When in doubt as to whether “hospitalization” occurred or was necessary, the AE should 
be considered serious. 
Hospitalization for elective treatment of a pre-existing condition that did not worsen from Baseline is not 
considered an AE. 
d) Results in persistent disability/incapacity 
• 
The term disability means a substantial disruption of a person’s ability to conduct normal life 
functions. 
• 
This definition is not intended to include experiences of relatively minor medical significance such as 
uncomplicated headache, nausea, vomiting, diarrhea, influenza, and accidental trauma (eg, sprained 
ankle) which may interfere with or prevent everyday life functions but do not constitute a substantial 
disruption. 
e) Is a congenital anomaly/birth defect 
f) 
Other (important medical events): 
• 
Medical or scientific judgment should be exercised in deciding whether SAE reporting is appropriate 
in other situations such as important medical events that may not be immediately life-threatening or 
result in death or hospitalization but may jeopardize the subject or may require medical or surgical 
intervention to prevent 1 of the other outcomes listed in the above definition. These events should 
usually be considered serious. 
Examples of such events include invasive or malignant cancers, intensive treatment in an emergency 
room or at home for allergic bronchospasm, blood dyscrasias or convulsions that do not result in 
hospitalization, or development of drug dependency or drug abuse.

57 
Recording and Follow-up of AE and/or SAE 
AE and SAE Recording 
• 
When an AE/SAE occurs, it is the responsibility of the Investigator to review all documentation (eg, 
hospital progress notes, laboratory reports, and diagnostics reports) related to the event. 
• 
The Investigator or designee will then record all relevant AE/SAE information in the CRF. Each event 
must be recorded separately. 
• 
It is not acceptable for the Investigator to send photocopies of the subject’s medical records in lieu of 
completion of the AE/SAE CRF page. 
• 
There may be instances when copies of medical records for certain cases are requested by the Sponsor. 
In this case, all subject identifiers, with the exception of the subject number, will be redacted on the 
copies of the medical records before submission to the Sponsor. 
• 
The Investigator will attempt to establish a diagnosis of the event based on signs, symptoms, and/or 
other clinical information. Whenever possible, the diagnosis (not the individual signs/symptoms) will 
be documented as the AE/SAE. 
Assessment of Intensity 
The Investigator will make an assessment of intensity for each AE and SAE reported during the study and 
assign it to 1 of the following categories: 
• 
Mild: An event that is easily tolerated by the subject, causing minimal discomfort and not interfering 
with everyday activities. 
• 
Moderate: An event that causes sufficient discomfort and interferes with normal everyday activities. 
• 
Severe: An event that prevents normal everyday activities. An AE that is assessed as severe should not 
be confused with an SAE. Severe is a category utilized for rating the intensity of an event; and both 
AEs and SAEs can be assessed as severe. 
An event is defined as ‘serious’ when it meets at least 1 of the predefined outcomes as described in the 
definition of an SAE, NOT when it is rated as severe. 
 
Assessment of Causality 
• 
The Investigator is obligated to assess the relationship between study treatment and each occurrence of 
each AE/SAE. The AE must be characterized as unrelated, unlikely to be related, or possibly related. 
o 
“Unrelated” is used if there is not a reasonable possibility that the study treatment caused the 
AE. 
o 
“Unlikely to be related” suggests that only a remote connection exists between the study 
treatment and the AE. Other conditions, including chronic illness, progression or expression 
of the disease state or reaction to concomitant therapy, appear to explain the reported AE. 
o 
“Possibly related” suggests that the association of the AE with the study treatment is 
unknown; however, the AE is not reasonably supported by other conditions. 
o 
“Probably related” conveys that there are facts, evidence, and/or arguments to suggest a 
causal relationship, rather than a relationship cannot be ruled out. 
• 
The Investigator will use clinical judgment to determine the relationship. 
• 
Alternative causes, such as underlying disease(s), concomitant therapy, and other risk factors, as well 
as the temporal relationship of the event to study treatment administration will be considered and 
investigated. 
• 
The Investigator will also consult the Investigator’s Brochure and/or Product Information, for 
marketed products, in his/her assessment. 

CONFIDENTIAL 
Protocol ADB244-002 – Amendment 1 
Confidential| ADB244-002| Amendmen1| Date:  25 FEB 2019 
58 
• 
For each AE/SAE, the Investigator must document in the medical notes that he/she has reviewed the 
AE/SAE and has provided an assessment of causality. 
• 
There may be situations in which an SAE has occurred and the Investigator has minimal information to 
include in the initial report to the Sponsor. However, it is very important that the Investigator always 
make an assessment of causality for every event before the initial transmission of the SAE data to the 
Sponsor. 
• 
The Investigator may change his/her opinion of causality in light of follow-up information and send a 
SAE follow-up report with the updated causality assessment. 
• 
The causality assessment is one of the criteria used when determining regulatory reporting 
requirements. 
 
Follow-up of AEs and SAEs 
• 
The Investigator is obligated to perform or arrange for the conduct of supplemental measurements 
and/or evaluations as medically indicated or as requested by the Sponsor to elucidate the nature and/or 
causality of the AE or SAE as fully as possible. This may include additional laboratory tests or 
investigations, histopathological examinations, or consultation with other health care professionals. 
• 
New or updated information will be recorded in the originally completed CRF. 
• 
The Investigator will submit any updated SAE data to the Sponsor within 24 hours of receipt of the 
information. 
 
Reporting of SAEs 
SAE Reporting via Paper SAE form 
• 
Reporting will be via paper as standard for the site. This will be using Novella template reporting form.

- Agree to use a male condom and have their partner use of a contraceptive method 
with a failure rate of <1% per year as described in the table below when having 
penile-vaginal intercourse with a female. 
• In addition, male subjects must refrain from donating sperm for the duration of the study and 
for 3 months after the last dose of study treatment. 
• Male subjects with a pregnant or breastfeeding partner must agree to remain abstinent from 
penile-vaginal intercourse or use a male condom during each episode of penile penetration 
during the protocol-defined time frame. 
Female subjects 
Female subjects of childbearing potential are eligible to participate if they practice abstinence or 
agree to use a highly effective method of contraception consistently and correctly as described in 
the table below.

Highly Effective Contraceptive Methods 
Highly Effective Contraceptive Methods That Are User Dependent a 
Failure rate of <1% per year when used consistently and correctly.  
Sexual Abstinence 
Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual 
intercourse during the entire period of risk associated with the study treatment. The reliability of sexual abstinence 
needs to be evaluated in relation to the duration of the study and the preferred and usual lifestyle of the subject. 
Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulationb 
• 
Oral. 
• 
Intravaginal. 
• 
Transdermal. 
Progestogen only hormonal contraception associated with inhibition of ovulation 
• 
Oral. 
• 
Injectable. 
Highly Effective Methods That Are User Independent a  
Implantable progestogen only hormonal contraception associated with inhibition of ovulationb 
• 
Intrauterine device (IUD). 
• 
Intrauterine hormone-releasing system (IUS). 
• 
Bilateral tubal occlusion. 
Vasectomized Partner 
A vasectomized partner is a highly effective birth control method provided that the partner is the sole male sexual 
partner of the Women of child-bearing potential and the absence of sperm has been confirmed. If not, an additional 
highly effective method of contraception should be used. 
NOTES: 
a Typical use failure rates may differ from those when used consistently and correctly. Use should be consistent with 
local regulations regarding the use of contraceptive methods for subjects participating in clinical studies. 
b Hormonal contraception may be susceptible to interaction with the study treatment, which may reduce the efficacy 
of the contraceptive method. Females must either practice abstinence from heterosexual contact or use one (1) of the 
highly effective contraceptive options described in the Appendix 5.  Females are not required to use two (2) highly 
effective methods of contraception. 
 
 
Pregnancy Testing: 
Pregnancy testing (urine) will be performed at times shown in Table 1.1 for all female subjects 
≥11 years, or female patients <11 years old who have started menstruating.

Collection of Pregnancy Information 
Male subjects with partners who become pregnant 
• After obtaining the necessary signed informed consent from the pregnant female partner 
directly, the Investigator will record pregnancy information on the appropriate form and 
submit it to the Sponsor within 24 hours of learning of the partner’s pregnancy. The female 
partner will also be followed to determine the outcome of the pregnancy. Information on the 
status of the mother and child will be forwarded to the Sponsor. Generally, the follow-up will 
be no longer than 6 to 8 weeks following the estimated delivery date. Any termination of the 
pregnancy will be reported regardless of fetal status (presence or absence of anomalies) or 
indication for the procedure. 
Female Subjects who become pregnant 
• The Investigator will collect pregnancy information on any female subject who becomes 
pregnant while participating in this study. Information will be recorded on the appropriate 
form and submitted to the Sponsor within 24 hours of learning of a subject’s pregnancy. The 
subject will be followed to determine the outcome of the pregnancy. The Investigator will 
collect follow-up information on the subject and the neonate and the information will be 
forwarded to the Sponsor. Generally, follow-up will not be required for longer than 6 to 
8 weeks beyond the estimated delivery date. Any termination of pregnancy will be reported, 
regardless of fetal status (presence or absence of anomalies) or indication for the procedure. 
• While pregnancy itself is not considered to be an AE or SAE, any pregnancy complication or 
elective termination of a pregnancy will be reported as an AE or SAE. A spontaneous 
abortion is always considered to be an SAE and will be reported as such. 
• Any post study pregnancy related SAE considered reasonably related to the study treatment 
by the Investigator will be reported to the Sponsor as described in Section 9.5.4. While the 
Investigator is not obligated to actively seek this information in former subjects, he or she 
may learn of an SAE through spontaneous reporting. 
• Any female subject who becomes pregnant while participating in the study will discontinue 
study treatment.
