What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants Who Achieved Success in Investigator's Static Global Assessment (ISGA) Score at Day 29

    ISGA assessed the severity of AD (except scalp) on a 5-point scale ranged from 0 (clear) to 4 (maximum severe), where higher scores indicate higher degree of AD. Grades for classification of severity: 0= clear (minor residual hypo/hyper pigmentation, no erythema or induration or papulation, no oozing or crusting), 1= almost clear (trace faint pink erythema, with barely perceptible induration or papulation and no oozing or crusting), 2= mild (faint pink erythema with mild induration or papulation and no oozing or crusting), 3= moderate (pink-red erythema with moderate induration or papulation with or without oozing or crusting) and 4= severe (deep or bright red erythema with severe induration or papulation and with oozing or crusting). Treatment success was defined as an ISGA score of Clear (0) or Almost Clear (1) with at least a 2-grade improvement from baseline.

    Measured: Day 29

  2. Number of Participants With Treatment-Emergent Adverse Events (AEs) And Serious Adverse Events (SAEs)

    An AE was any untoward medical occurrence attributed to a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; Initial or prolonged inpatient hospitalization; life threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between first dose of study drug to the end of study, that were absent before treatment or that worsened relative to pre-treatment state.

    Measured: AEs: Baseline (Day 1) up to Day 29, SAEs: Baseline (Day 1) up to Day 36

  3. Number of Participants With Clinically Significant Change From Baseline in Electrocardiogram (ECG) Findings at Day 8

    ECG parameters that were analyzed: PR interval, QRS interval, QT interval and corrected QT interval based on Fridericia's formula (QTcF). Clinical significance of change from baseline in ECG findings was determined by investigator.

    Measured: Baseline, Day 8

  4. Number of Participants With Clinically Significant Change From Baseline in Vital Signs at Day 36

    Following parameters were analyzed for examination of vital signs: systolic and diastolic blood pressure, pulse, respiratory rate and body temperature. Vital sign measurements were performed with the participant in the seated or supine position and after the participant had been calmly sitting or lying face up for a minimum of 5 minutes. Clinical significance of change from baseline value was determined by investigator.

    Measured: Baseline (Day 1), Day 36

  5. Number of Participants With Clinically Significant Laboratory Values

    Laboratory values included: Alkaline Phosphatase, Alanine Aminotransferase, Aspartate Aminotransferase, Albumin, Bilirubin, Blood Urea Nitrogen, Glucose, Hematocrit, Hemoglobin, Leukocytes, Lymphocytes, Monocytes, Neutrophils, Platelets, Basophils, Eosinophils, Erythrocytes, Potassium, Protein, Sodium. Clinically significant laboratory abnormalities were defined as abnormal laboratory test values that have clinical manifestations or require medical intervention, as per investigator's discretion.

    Measured: Baseline up to Day 36

  6. Percentage of Participants With Local Tolerability Symptoms at Baseline

    Local tolerability symptoms (burning/stinging) were assessed in participants at sites of study drug application. Symptoms were assessed on 4-point scale ranging from 0 to 3, where 0 = none (no stinging/burning), 1 = mild (slight warm, tingling sensation); 2= moderate (definite warm; tingling/stinging sensation that is somewhat bothersome and severe); 3= severe (hot, tingling/stinging sensation that caused definite discomfort). Higher scores indicated more severe symptoms. Percentage of participants with each level of local tolerability (none, mild, moderate, severe) symptoms were reported.

    Measured: Baseline (Day 1)

  7. Percentage of Participants With Local Tolerability Symptoms at Day 8

    Local tolerability symptoms (burning/stinging) were assessed in participants at sites of study drug application. Symptoms were assessed on 4-point scale ranging from 0 to 3, where 0= none (no stinging/burning), 1 = mild (slight warm, tingling sensation); 2= moderate (definite warm; tingling/stinging sensation that is somewhat bothersome and severe); 3= severe (hot, tingling/stinging sensation that caused definite discomfort). Higher scores indicated more severe symptoms. Percentage of participants with each level of local tolerability (none, mild, moderate, severe) symptoms were reported.

    Measured: Day 8

  8. Percentage of Participants With Local Tolerability Symptoms at Day 15

    Local tolerability symptoms (burning/stinging) were assessed in participants at sites of study drug application. Symptoms were assessed on 4-point scale ranging from 0 to 3, where 0= none (no stinging/burning), 1= mild (slight warm, tingling sensation); 2= moderate (definite warm; tingling/stinging sensation that is somewhat bothersome and severe); 3= severe (hot, tingling/stinging sensation that caused definite discomfort). Higher scores indicated more severe symptoms. Percentage of participants with each level of local tolerability (none, mild, moderate, severe) symptoms were reported.

    Measured: Day 15

  9. Percentage of Participants With Local Tolerability Symptoms at Day 22

    Local tolerability symptoms (burning/stinging) were assessed in participants at sites of study drug application. Symptoms were assessed on 4-point scale which ranges from 0 to 3, where 0 = none (no stinging/burning), 1 = mild (slight warm, tingling sensation); 2= moderate (definite warm; tingling/stinging sensation that is somewhat bothersome and severe); 3= severe (hot, tingling/stinging sensation that caused definite discomfort). Higher scores indicate high severity of symptoms. In this outcome, percentage of participants with each level of local tolerability (none, mild, moderate, severe) symptoms were reported.

    Measured: Day 22

  10. Percentage of Participants With Local Tolerability Symptoms at Day 29

    Local tolerability symptoms (burning/stinging) were assessed in participants at sites of study drug application. Symptoms were assessed on 4-point scale which ranges from 0 to 3, where 0 = none (no stinging/burning), 1 = mild (slight warm, tingling sensation); 2= moderate (definite warm; tingling/stinging sensation that is somewhat bothersome and severe); 3= severe (hot, tingling/stinging sensation that caused definite discomfort).
