Brief summary:
This is a Phase I/IIa Open-Label, Dose-Escalation Study to Determine the Safety, Tolerability, and Efficacy of AR100DP1 in Health Subjects, and Subjects with Mild to Moderate Atopic Dermatitis.

Detailed description:
This phase I/IIa study will be composed of a Phase I study, which includes 14 days of treatment with AR100DP1 followed by 2 weeks of follow-up period to find the maximum tolerated dose (MTD) of AR100DP1 and a following single-arm Phase IIa study with 28 days of treatment followed by 2 weeks of follow-up period to evaluate the efficacy of AR100DP1 with the recommended Phase II dose (RP2D) in treating atopic dermatitis on target lesion. Target lesion area(s) is defined as one or multiple patches of lesion areas selected by the investigator for topical administration of AR100DP1. The size of target lesion area(s) is 0.5-5% body surface area (BSA) and the maximum is 750 cm2 (maximal treated area, inclusive) in this study. Eligible healthy subjects in Phase I will have the test skin area(s) of 750 cm2 from chest and abdomen. Eligible subjects with mild to moderate AD in Phase IIa will have target lesion area(s) selected by the investigator. The skin area treated with AR100DP1 will be recorded for AR100DP1 topical administration before dosing. AR100DP1 should be topically administered twice daily on the test skin area(s) of 750 cm2 of eligible healthy subjects for 14 days in Phase I study. The administration of AR100DP1 should be topically applied twice daily on target lesion area(s) (0.5-5% BSA, maximum as 750 cm2, inclusive) of eligible subjects with mild to moderate AD for 28 days in Phase IIa study.

Arms:
arm 1: Subjects topically apply AR100DP1 twice per day with at least 4 hour interval. The daily dosage of 1.25% AR100DP1 topical administration is 31.25 mg/day (1.25% × 1,250 × 2 = 31.25). arm 2: Subjects topically apply AR100DP1 twice per day with at least 4 hour interval. The daily dosage of 2.5% AR100DP1 topical administration is 62.5 mg/day (2.5% × 1,250 × 2 = 62.5). arm 3: Subjects topically apply AR100DP1 twice per day with at least 4 hour interval. The daily dosage of 5% AR100DP1 topical administration is 125 mg/day (5% × 1,250 × 2 = 125). arm 4: Subjects topically apply AR100DP1 twice per day with at least 4 hour interval. The daily dosage of 5% AR100DP1 topical administration is 125 mg/day (5% × 1,250 × 2 = 125).

4. 
Dosage and administration:  
Dosage:  
1.25%, 2.5% and 5% AR100DP1 
Administration:  
In Phase I study, healthy subjects will have 14 days of treatment with AR100DP1 on the test 
skin area(s) of 750 cm2 from chest and abdomen, whereas in Phase IIa study, subjects with 
mild to moderate AD will have 28 days of treatment with AR100DP1 on target lesion area(s). 
Target lesion area(s) is defined as one or multiple patches of lesion areas selected by the 
investigator for topical administration of AR100DP1. The size of target lesion area(s) is 0.5-
5% body surface area (BSA) and the maximum is 750 cm2 (maximal treated area, inclusive) 
in this study. The unit of AR100DP1 is a tube containing 20 grams (net weight) of AR100DP1 
ointment. Eligible healthy subjects in Phase I will have the test skin area(s) of 750 cm2 from 
chest and abdomen. For each topical administration in Phase I study, 2.5 FTUs of AR100DP1 
(approximately 1,250 (± 100) mg for ~750 cm2) will be applied to cover the test skin area(s) 
of eligible healthy subjects. AR100DP1 should be topically administered twice daily on the 
test skin area(s) of 750 cm2 of eligible healthy subjects for 14 days in Phase I study.

Eligible subjects with mild to moderate AD in Phase IIa will have target lesion area(s) 
selected by the investigator.The target lesion area(s) will be selected, measured in cm2, and 
recorded for AR100DP1 topical administration at Screening. The size of each patch of the 
target lesion area(s) will be traced, measured, and recorded at each following visit after 
Screening. If total lesion area of subjects is beyond 750 cm2, other areas rather than the 
selected lesion areas are allowed to be treated routinely with prescribed topical medication 
during the study. For each topical administration in Phase IIa study, corresponding FTU(s) 
(approximately 1 FTU= 0.5 gram for 300 cm2) of AR100DP1 will be applied on target lesion 
area(s) (0.5-5% BSA, maximum as 750 cm2, inclusive) of eligible subjects with mild to 
moderate AD. AR100DP1 should be topically administered twice daily for 28 days in Phase 
IIa study. The skin area for AR100DP1 administration would be unchanged even when target 
lesion area(s) alters during the study. 
5. Mechanism of action (if known): Reduction of the expression of IgE, IL-17A, IL-6, IL-4, IL-
1β and TNF-α. Further investigation is still ongoing.

VIII. 
Study procedures: 
This Phase I/IIa study will be composed of a Phase I study in healthy subjects, and a Phase IIa 
study in subjects with mild to moderate atopic dermatitis. Phase I study includes 14 days of 
treatment with AR100DP1 on the test skin area(s) of 750 cm2 from chest and abdomen, followed 
by 2 weeks of follow-up period to find the maximum tolerated dose (MTD) of AR100DP1. A 
single-arm Phase IIa study will be conducted with 28 days of treatment followed by 2 weeks of 
follow-up period to evaluate the efficacy of AR100DP1 with the recommended Phase II dose 
(RP2D) in treating subjects with mild to moderate atopic dermatitis (AD) on target lesion area(s). 
Target lesion area(s) is defined as one or multiple patches of lesion areas selected by the 
investigator for topical administration of AR100DP1. The size of target lesion area(s) is 0.5-5%

body surface area (BSA) and the maximum is 750 cm2 (maximal treated area, inclusive) in this 
study. Eligible healthy subjects in Phase I will have the test skin area(s) of 750 cm2 from chest and 
abdomen. Eligible subjects with mild to moderate AD in Phase IIa will have target lesion area(s) 
selected by the investigator. The skin area treated with AR100DP1 will be recorded for AR100DP1 
topical administration before dosing. AR100DP1 should be topically administered twice daily on 
the test skin area(s) of 750 cm2 of eligible healthy subjects for 14 days in Phase I study. The 
administration of AR100DP1 should be topically applied twice daily on target lesion area(s) (0.5-
5% BSA, maximum as 750 cm2, inclusive) of eligible subjects with mild to moderate AD for 28 
days in Phase IIa study. 
During Phase I, the study will be conducted in the conventional 3+3 design of dose escalation in 
three cohorts with doses as 1.25%, 2.5% and 5%, to determine the MTD of AR100DP1. The first 3 
subjects of Cohort 1 (1.25%, n=3 or 6) is the sentinel group, in which subjects will be enrolled 
sequentially to have 7 days of AR100DP1 administration. After 7 days of dosing, the safety data 
will be reviewed by the investigator before the next subject of the first 3 subjects in Cohort 1 is 
allowed to have AR100DP1 administration. The dose of AR100DP1 will be escalated to the 
subsequent cohort when there is no dose-limiting toxicity (DLT) in 3 subjects or only 1 DLT in 6 
subjects.  
The DLT is defined as any adverse event (AE) ≥ Grade 2 (Guidance for Industry: Toxicity Grading 
Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials, 
issued by United States Food and Drug Administration in September 2007), that is considered to be 
causally related (possibly, probably, or definitely related) to AR100DP1 as judged by the 
investigator during Visit 2-6 (DLT observation period). The definition of Grade 5 (death related to 
AE) was added to this grading system as it was not defined in the guidance. The safety results will 
be reviewed by the Data and Safety Monitoring Board (DSMB) after the completion of each 
cohort. The DSMB will provide the comments of the decision and determine if it is safe to proceed 
to the next dose level or stopping the dose escalation. For safety concern, the DSMB will consider 
to postpone the dose escalation and recruit more subjects into the concurrent dose cohort for 
evaluation of safety information. The DSMB will give its recommendation of the RP2D while the 
sponsor will determine the dosage applied in the subsequent Phase IIa study. 
In the single-arm Phase IIa study, 12 evaluable subjects with mild to moderate AD are planned to 
be enrolled and treated with AR100DP1 at the dose determined by the sponsor for 28 days of 
AR100DP1 treatment period followed by a 14-day follow-up period.

Study Intervention Discontinuation and Subject Withdrawal for Discontinuation 
3.1 Study Intervention Discontinuation 
When the discontinuation is confirmed, subjects will be requested to complete the coming 
scheduled visit as early termination (ET) Visit within 7 days after the last dose. When the 
decision of withdrawal is made at the scheduled visit prior to the end of treatment (EOT), that 
same visit will be deemed as ET Visit, which means the assessments scheduled for ET will be 
evaluated. When the decision of withdrawal is made at an Unscheduled Visit, the same 
Unscheduled Visit will be deemed as ET Visit and the assessments at this visit will follow 
those defined at ET visit. When the decision of withdrawal is made after the treatment period 
(EOT) has been completed, subjects are requested to return for assessments scheduled at Final 
Visit within 7 days after the decision is made. AEs will be followed up until resolved or 
stable. Alternatively, if the subject does not agree to this option or is not able to physically 
attend the visit, a modified follow up by telephone contact should be arranged, if agreed to by 
the subject and in compliance with local data privacy laws/practices. 
 
3.2 Subject Withdrawal from the study 
Subjects are free to withdraw from participation in the study at any time and for any reason, or 
no reason at all upon request, without prejudice. 
An investigator may discontinue or withdraw a subject from the study for the following 
reasons: 
1. 
Any pathological event, clinical adverse event, laboratory abnormality, intercurrent 
illness, or any occurrence or change in the subject’s physically and/or psychologically 
status giving indication to the investigator that further participation in the study may not 
be the best interest of the subject. 
2. 
Subject develops DLT during the study period. (Phase I only)

4. 
Statistical method(s) for efficacy/safety evaluations: 
General Approach 
Descriptive statistics will be provided for all endpoints by dose level (dose level of Phase I, 
and RP2D of Phase IIa). 
Continuous variables will be summarized by reporting the number of observations, mean, 
standard deviation, median, interquartile range (IQR = third quartile (Q3) - first quartile(Q1)), 
Q1, Q3, minimum and maximum. 
Categorical variables will be summarized by using frequency tables showing the number and 
percentage of subjects within a particular category. 
Analysis of the Primary Efficacy Endpoint(s) 
The primary endpoint of the Phase I study is to determine MTD of AR100DP1 in healthy 
subjects, which is a safety endpoint. Such endpoint will be observed on evaluable subjects. 
While in the Phase IIa study, the primary endpoint is the proportion of subjects with the IGA 
score of 0 or 1 (responder) on Day 29. Frequency tables of response rate and change from 
baseline of IGA score will be presented respectively The last-observation-carried-forward 
(LOCF) method will be applied if all subsequent visits are missing. 
Analysis of the Secondary Endpoint(s) 
Efficacy Endpoints: 
For Proportion of subjects with the IGA score of 0 or 1. 
Change from baseline of target lesion area(s), change from baseline in pruritus NRS of itch 
level on target lesion area(s), change from baseline in signs of atopic dermatitis (erythema, 
edema/papulation, excoriation and lichenification) on target lesion area(s), and change from 
baseline in the total score of the POEM will be analyzed by using descriptive statistics, p-
value of Wilcoxon sign-rank test or paired-t test will be given to test the improvement. 
Frequency tables of change from baseline will be presented for pruritus NRS of itch level, and

Page 19 of 21 
the total score of the POEM as appropriate. 
Safety Analyses 
Adverse events will be coded by employing Medical Dictionary for Regulatory Activities 
(MedDRA). The version of MedDRA used for coding should be agreed by sponsor before 
coding starts. AE will be displayed by subject count, i.e. each subject is counted only once 
within each category of AE. The incidence of AEs will be presented by System Organ Class 
(SOC) and preferred term groupings. For Phase I, incidence of DLT will be presented on both 
ITT population and evaluable subjects. The information of AEs, such as start date, stop date, 
severity, relationship, expectedness (only for SAE), outcome, and duration, should be listed. 
Adverse events leading to premature discontinuation from the study intervention and serious 
adverse events (SAEs) should be presented either in a table or a listing. 
Findings in physical examinations will be displayed for each individual system. Findings in 
ECG will be tabulated with transition from baseline. Net changes from baseline laboratory 
parameters, weight and vital signs will be analyzed by using descriptive statistics with p-value 
of Wilcoxon sign-rank test or paired-t test given. The baseline is defined as the closest test 
result prior to the first dosing of AR100DP1 topical administration.
