Group Intervention Description Placebo Placebo * Subcutaneous (SC) injection of the matching placebo * Treatment on Day 1, 15, 29, and 43 for a total 4 biweekly doses BxC-I17e BxC-I17e * Subcutaneous (SC) injection of 50, or 100 ug BxC-I17e * Treatment on Day 1, 15, 29, and 43 for a total 4 biweekly doses
- Primary Outcome Measures
Name Time Method Incidence of treatment-emergent adverse events (TEAEs) Baseline to Week 26 Incidence of treatment-emergent adverse events as assessed by CTCAE v5.0
- Secondary Outcome Measures
Name Time Method Proportion of patients who achieved the Investigator's Global Assessment (IGA) score of 0 or 1 Baseline to Week 14 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).
Change and percent change in Dermatology Life Quality Index (DLQI) Baseline to Week 14 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
Changes in the level of total Immunoglobulin E (IgE) in the serum and correlation with other parameters Baseline to Week 14 The level of biomarkers in serum
Incidence, severity and relationship of adverse events(AEs) Baseline to Week 26 Incidence, severity and relationship of adverse events as assessed by CTCAE v5.0
Number of abnormalities and change from baseline in Vital signs Baseline to Week 26 Supine blood pressure and pulse rate, tympanic temperature, and respiratory rate
Number of abnormalities in clinical laboratory parameter Baseline to Week 26 Hematology, clinical chemistry, and urinalysis parameters
Frequency and proportion of clinically significant finding of physical examination Baseline to Week 26 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
Number of abnormalities in 12-lead electrocardiogram (ECG) Baseline to Week 26 PR interval, QRS interval, RR interval, QT interval and QT interval using Friderica's correction (QTcF)
Change and percent change in Body Surface Area (BSA) Baseline to Week 14 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).
Change and percent change in Eczema Area and Severity Index (EASI) Baseline to Week 14 The EASI is a composite index with scores ranging from 0 to 72. Higher scores indicates worse condition.
Change and percent change in Pruritus Numerical Rating Scale (NRS) Baseline to Week 14 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.
Change and percent change in Patient-Oriented Eczema Measure (POEM) Baseline to Week 14 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.
Changes in the level of eosinophils in the serum and correlation with other parameters Baseline to Week 14 The level of biomarkers in serum
Changes in the level of Thymus Activation Regulated Chemokine (TARC) in the serum and correlation with other parameters Baseline to Week 14 The level of biomarkers in serum
Changes in the level of Pulmonary Activation-Regulated Chemokine (PARC) in the serum and correlation with other parameters Baseline to Week 14 The level of biomarkers in serum
Changes in the level of Macrophage-Derived Chemokine (MDC) in the serum and correlation with other parameters Baseline to Week 14 The level of biomarkers in serum
Change and percent change in Scoring Atopic Dermatitis (SCORAD) Baseline to Week 14 The SCORAD is a clinical tool for assessing the severity of Atopic dermatitis. Total score ranged from 0 (absent disease) to 103 (severe disease).

Changes in the level of periostin in the serum and correlation with other parameters Baseline to Week 14 The level of biomarkers in serum
Changes in the level of total Interleukin-13 (IL-13) in the serum and correlation with other parameters Baseline to Week 14 The level of biomarkers in serum
Changes in the level of total Interleukin-31 (IL-31) in the serum and correlation with other parameters Baseline to Week 14 The level of biomarkers in serum
Changes in the level of total Interleukin-22 (IL-22) in the serum and correlation with other parameters Baseline to Week 14 The level of biomarkers in serum
