4. Prior exposure to any investigational systemic treatment or is currently enrolled in another clinical study

5. Significant concomitant illness or history of significant illness such as cardiac, renal, neurological, endocrinological, metabolic or lymphatic disease, or any other illness or condition that would adversely affect the patient's participation in this study

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence of treatment-emergent adverse events (TEAEs)	Incidence of treatment-emergent adverse events as assessed by CTCAE v5.0	Baseline to Week 26
Secondary	Incidence, severity and relationship of adverse events(AEs)	Incidence, severity and relationship of adverse events as assessed by CTCAE v5.0	Baseline to Week 26
Secondary	Number of abnormalities and change from baseline in Vital signs	Supine blood pressure and pulse rate, tympanic temperature, and respiratory rate	Baseline to Week 26
Secondary	Number of abnormalities in 12-lead electrocardiogram (ECG)	PR interval, QRS interval, RR interval, QT interval and QT interval using Friderica's correction (QTcF)	Baseline to Week 26
Secondary	Number of abnormalities in clinical laboratory parameter	Hematology, clinical chemistry, and urinalysis parameters	Baseline to Week 26
Secondary	Frequency and proportion of clinically significant finding of physical examination	Assessments of the following body categories : skin, HEENT (head, eye, ears, nose, and throat), cardiovascular, respiratory, gastrointestinal, endocrine/metabolic, genitourinary, psychiatric, hematologic/lymphatics, musculoskeletal, neurologic, hepatic, and allergic/immunologic	Baseline to Week 26
Secondary	Proportion of patients who achieved the Investigator's Global Assessment (IGA) score of 0 or 1	The IGA is an assessment instrument used in clinical studies to rate the severity of Atopic dermatitis globally, based on a 5-point scale ranging from 0 (clear) to 4 (severe).	Baseline to Week 14
Secondary	Change and percent change in Body Surface Area (BSA)	The BSA affected by atopic dermatitis will be assessed for each major section of the body (head, trunk, arms, and legs). Extent and intensity of eczema as well as subjective signs (insomnia, etc.) are assessed and scored. Total score ranges from 0 (absent disease) to 103 (severe disease).	Baseline to Week 14
Secondary	Change and percent change in Eczema Area and Severity Index (EASI)	The EASI is a composite index with scores ranging from 0 to 72. Higher scores indicates worse condition.	Baseline to Week 14
Secondary	Change and percent change in Scoring Atopic Dermatitis (SCORAD)	The SCORAD is a clinical tool for assessing the severity of Atopic dermatitis. Total score ranged from 0 (absent disease) to 103 (severe disease).	Baseline to Week 14
Secondary	Change and percent change in Pruritus Numerical Rating Scale (NRS)	The Pruritus NRS is a simple assessment tool used to report the intensity of their pruritus (itch) ranges from 0 to 10 with 0 being 'no itch' and 10 being the' worst itch imaginable.	Baseline to Week 14
Secondary	Change and percent change in Dermatology Life Quality Index (DLQI)	The DLQI is a validated questionnaire designed to measure the impact of skin disease on the Quality of Life. The higher the score, the greater the impact is on the quality of life	Baseline to Week 14
Secondary	Change and percent change in Patient-Oriented Eczema Measure (POEM)	The POEM is a validated 7-item questionnaire used to assess disease symptoms with a scoring system of 1 to 28. The higher score, the higher morbidity.	Baseline to Week 14
Secondary	Changes in the level of eosinophils in the serum and correlation with other parameters	The level of biomarkers in serum	Baseline to Week 14
Secondary	Changes in the level of Thymus Activation Regulated Chemokine (TARC) in the serum and correlation with other parameters	The level of biomarkers in serum	Baseline to Week 14
Secondary	Changes in the level of Pulmonary Activation-Regulated Chemokine (PARC) in the serum and correlation with other parameters	The level of biomarkers in serum	Baseline to Week 14
Secondary	Changes in the level of eotaxin-3 in the serum and correlation with other parameters	The level of biomarkers in serum	Baseline to Week 14
Secondary	Changes in the level of Macrophage-Derived Chemokine (MDC) in the serum and correlation with other parameters	The level of biomarkers in serum	Baseline to Week 14
Secondary	Changes in the level of periostin in the serum and correlation with other parameters	The level of biomarkers in serum	Baseline to Week 14
Secondary	Changes in the level of total Immunoglobulin E (IgE) in the serum and correlation with other parameters	The level of biomarkers in serum	Baseline to Week 14
Secondary	Changes in the level of total Interleukin-13 (IL-13) in the serum and correlation with other parameters	The level of biomarkers in serum	Baseline to Week 14
Secondary	Changes in the level of total Interleukin-22 (IL-22) in the serum and correlation with other parameters	The level of biomarkers in serum	Baseline to Week 14
Secondary	Changes in the level of total Interleukin-31 (IL-31) in the serum and correlation with other parameters	The level of biomarkers in serum	Baseline to Week 14
