ListOutcomeTime frameDescription
PrimarySuccess rate in Investigator's Global Assessment at Week 44 weeks
Investigator's Global Assessment measures the severity of atopic dermatitis (0 = Clear; 1 = Almost clear; 2 = Mild disease; 3 = Moderate disease; 4 = Severe disease/Very severe disease) of clinical characteristics (erythema, infiltration, papulation, oozing, and crusting). A higher score represents a severer clinical impression on the patient's severity based on investigator/clinician's judgment. The efficacy is assessed by the percentage of subjects with Investigator's Global Assessment score of 0 or 1 with improvement by at least 2 grades. Subjects with missing Investigator's Global Assessment data will be handled as non-responders.
SecondaryChange from baseline in Investigator's Global Assessment at Week 44 weeks
Investigator's Global Assessment measures the severity of atopic dermatitis (0 = Clear; 1 = Almost clear; 2 = Mild disease; 3 = Moderate disease; 4 = Severe disease/Very severe disease) of clinical characteristics (erythema, infiltration, papulation, oozing, and crusting). A higher score represents a severer clinical impression on the patient's severity based on investigator/clinician's judgment. The efficacy is assessed by the change from baseline in Investigator's Global Assessment at Week 4.
SecondarySuccess rate in Eczema Area and Severity Index 75 (improvement of ≥75% in Eczema Area and Severity Index) and at Week 44 weeks
Eczema Area and Severity Index measures the severity of skin symptoms. The maximum Eczema Area and Severity Index score is 72 points. A higher score represents a severer clinical impression on the patient's severity based on investigator/clinician's judgment. The efficacy is assessed by the success rate in Eczema Area and Severity Index 75 (improvement of ≥75% in Eczema Area and Severity Index) at Week 4.
SecondaryEczema Area and Severity Index 90 (improvement of ≥90% in Eczema Area and Severity Index) at week 44 weeks
Eczema Area and Severity Index measures the severity of skin symptoms. The maximum Eczema Area and Severity Index score is 72 points. A higher score represents a severer clinical impression on the patient's severity based on investigator/clinician's judgment. The efficacy is assessed by success rate in Eczema Area and Severity Index 90 (improvement of ≥90% in Eczema Area and Severity Index) and at Week 4.
SecondaryEczema Area and Severity Index 50 (improvement of ≥50% in Eczema Area and Severity Index) at week 44 weeks
Eczema Area and Severity Index measures the severity of skin symptoms. The maximum Eczema Area and Severity Index score is 72 points. A higher score represents a severer clinical impression on the patient's severity based on investigator/clinician's judgment. The efficacy is assessed by success rate in Eczema Area and Severity Index 50 (improvement of ≥50% in Eczema Area and Severity Index) and at Week 4.
SecondaryChange from baseline in the total score of Eczema Area and Severity Index and each clinical sign score at Week 44 weeks
Eczema Area and Severity Index measures the severity of skin symptoms. The maximum Eczema Area and Severity Index score is 72 points. A higher score represents a severer clinical impression on the patient's severity based on investigator/clinician's judgment. The efficacy is assessed by change from baseline in the total score of Eczema Area and Severity Index and each clinical sign score at Week 4.
SecondaryChange from baseline in Verbal Rating Scale for Pruritus at Week 44 weeks
The Verbal Rating Scale measures the intense pruritus in the past 24 hours following Verbal Rating Scale criteria( 0: None,1: Mild, 2: Moderate, 3: Severe). A higher score represents a severer clinical impression on the patient's severity based on investigator/clinician's judgment. The efficacy is assessed by Change from baseline in Verbal Rating Scale (VRS) for Pruritus at Week 4
SecondaryChange from baseline in Verbal Rating Scale for pruritus up to Day 77 Days
The Verbal Rating Scale measures the intense pruritus in the past 24 hours following Verbal Rating Scale criteria( 0: None,1: Mild, 2: Moderate, 3: Severe). A higher score represents a severer clinical impression on the patient's severity based on investigator/clinician's/subjects' judgment. The efficacy is assessed by Change from baseline in Verbal Rating Scale for Pruritus up to day 7.
SecondaryChange from baseline in the total score of Patient-Oriented Eczema Measure at Week 44 weeks
Eczema will be evaluated according to Patient-Oriented Eczema Measure .The subjects will answer 7 questions and describe their eczema. The investigator will confirm their responses and record the results in the source document and CRF. The total score of POEM is 28 points at the most. A higher score represents a severer clinical impression on the patient's severity based on investigator/clinician's judgment. The efficacy is assessed by Change from baseline in the total score of Patient-Oriented Eczema Measure at Week 4
SecondaryChange from baseline in the total score of Dermatology Life Quality Index at week 44 weeks
The effects of symptoms on daily life will be evaluated according to Dermatology Life Quality Index (.The subjects will answer a total of 10 questions and describe the effects of the symptoms on their daily life (scale: symptoms, emotions, and functioning). A higher score represents a severer clinical impression on the patient's severity based on investigator/clinician's judgment. The efficacy is assessed by change from baseline in the total score of Dermatology Life Quality Index at week 4.
SecondaryChange from baseline in the total affected Body Surface Area (percent) at Week 44 weeksThe efficacy is assessed by change from baseline in the total affected Body Surface Area (percent) at Week 4.
SecondarySuccess rate in Investigator's Global Assessment at Week 2424 weeks
Investigator's Global Assessment measures the severity of atopic dermatitis (0 = Clear; 1 = Almost clear; 2 = Mild disease; 3 = Moderate disease; 4 = Severe disease/Very severe disease) of clinical characteristics (erythema, infiltration, papulation, oozing, and crusting). A higher score represents a severer clinical impression on the patient's severity based on investigator/clinician's judgment. The efficacy is assessed by the percentage of subjects with Investigator's Global Assessment score of 0 or 1 with improvement by at least 2 grades. Subjects with missing Investigator's Global Assessment data will be handled as non-responders.
