Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of IGA Responders at Week 16	Investigator's Global Assessment (IGA) score is used to determine the severity of atopic dermatitis symptoms and clinical response to treatment. It reflects a subject's overall disease severity for the whole body. The scale includes 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate and 4 = severe. It is a static scale and does not refer to previous status of the subject.; IGA response is defined as achievement of an IGA score of 0 or 1 with a 2-point reduction from baseline without use of confounding therapy (e.g. rescue medication) up to the assessment time point.; Treatment discontinuations for lack of efficacy or adverse event are considered non-responders.; Percentage of responders was calculated based on a logistic regression model with response as outcome variable and treatment (dose as categorical variable) and baseline IGA as covariates.	Week 16
Secondary	Percent Change From Baseline in EASI Score at Week 16	Eczema Area and Severity Index (EASI) is used to assess the extend and severity of atopic dermatitis on a scale from 0 to 72 where 72 is worst eczema.	Baseline, Week 16
Secondary	Percent Change From Baseline in EASI Score Over Time	Eczema Area and Severity Index (EASI) is used to assess the extend and severity of atopic dermatitis on a scale from 0 to 72 where 72 is worst eczema.	Baseline, Week 2, Week 4, Week 6, Week 8, Week 12
Secondary	Percentage of EASI50 Responders Over Time	Eczema Area and Severity Index (EASI) is used to assess the extend and severity of atopic dermatitis on a scale from 0 to 72 where 72 is worst eczema.; EASI50 response is defined as achieving = 50% improvement (reduction) in EASI score compared to baseline without use of confounding therapy (e.g. rescue medication) up to the assessment time point.; Treatment discontinuations for lack of efficacy or adverse event are considered non-responders.; Percentage of responders was calculated based on a logistic regression model with response as outcome variable and treatment (dose as categorical variable) and baseline EASI as covariates	Week 2, Week 4, Week 6, Week 8, Week 12, Week 16
Secondary	Percentage of EASI75 Responders Over Time	Eczema Area and Severity Index (EASI) is used to assess the extend and severity of atopic dermatitis on a scale from 0 to 72 where 72 is worst eczema.; EASI75 response is defined as achieving = 75% improvement (reduction) in EASI score compared to baseline without use of confounding therapy (e.g. rescue medication) up to the assessment time point.; Treatment discontinuations for lack of efficacy or adverse event are considered non-responders.; Percentage of responders was calculated based on a logistic regression model with response as outcome variable and treatment (dose as categorical variable) and baseline EASI as covariates	Week 2, Week 4, Week 6, Week 8, Week 12, Week 16
Secondary	Percentage of IGA Responders Over Time	Investigator's Global Assessment (IGA) score is used to determine the severity of atopic dermatitis symptoms and clinical response to treatment. It reflects a subject's overall disease severity for the whole body. The scale includes 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate and 4 = severe. It is a static scale and does not refer to previous status of the subject.; IGA response is defined as achievement of an IGA score of 0 or 1 with a 2-point reduction from baseline without use of confounding therapy (e.g. rescue medication) up to the assessment time point.; Treatment discontinuations for lack of efficacy or adverse event are considered non-responders.; Percentage of responders was calculated based on a logistic regression model with response as outcome variable and treatment (dose as categorical variable) and baseline IGA as covariates.	Week 2, Week 4, Week 6, Week 8, Week 12
Secondary	Number of Patients With Adverse Events	An adverse event (AE) is any untoward medical occurrence (e.g., any unfavorable and unintended sign [including abnormal laboratory findings], symptom or disease) in a subject or clinical investigation subject after providing written informed consent for participation in the study until the end of study visit. Therefore, an AE may or may not be temporally or causally associated with the use of a medicinal (investigational) product.	Up to week 20
