Participants With Investigator's Global Assessment (IGA) Score of 0 (Clear) or 1 (Almost Clear) at Week 16 Primary · Week 16

IGA is used to evaluate the severity of atopic dermatitis. It is a 5-point score ranging from 0 (clear) to 4 (severe).

Participants Achieving at Least 75% Reduction in Eczema Area and Severity Index (EASI) at Week 16 Primary · Week 16

EASI is used to evaluate the extent and severity of atopic dermatitis. It is a composite score ranging from 0 to 72 with a higher score indicating a more extensive and/or severe condition.

Reduction of Worst Daily Pruritus Numeric Rating Scale (NRS) (Weekly Average) of at Least 4 From Baseline to Week 16 Secondary · Week 0 to Week 16

Worst Daily Pruritus NRS is used by the participant to evaluate their worst itch severity over the past 24 hours. The score ranges from 0 ('no itch') to 10 ('worst itch imaginable') on an 11-point scale.

Change in Scoring Atopic Dermatitis (SCORAD) From Baseline to Week 16 Secondary · Week 0 to Week 16

SCORAD is used to evaluate the extent and severity of atopic dermatitis as well as subjective symptoms. The score ranges from 0 to 103 with a higher score indicating a more extensive and/or severe condition.

Change in Dermatology Life Quality Index (DLQI) Score From Baseline to Week 16 Secondary · Week 0 to Week 16

DLQI is used by the participant to evaluate the impact of their condition on 10 different aspects of health-related quality of life (HRQoL) over the last week. Each item is scored on a 4-point Likert scale ranging from 0 (not at all/not relevant) to 3 (very much). The total score which is the sum of the 10 items ranges from 0 to 30, with a higher score indicating a poorer HRQoL.

Frequency of Anti-drug Antibodies (ADA) Secondary · Week 0 to Week 16, Week 16 to Week 32

Presence of ADA from Week 0 to Week 32 was measured. Data were reported in the following categories: positive (presence of ADA at baseline and/or presence of ADA at at least 1 post-baseline assessment), perishing (presence of ADA at baseline and absence of ADA at all post-baseline assessments), negative (absence of ADA at all assessments), no post-baseline ADA assessment. Perishing ADAs were not assessed in the continuation treatment period.

Sponsor's own description

Primary objective: To demonstrate that tralokinumab in combination with topical corticosteroids (TCS) is superior to placebo in combination with TCS in treating moderate-to-severe atopic dermatitis (AD). Secondary objectives: To evaluate the efficacy of tralokinumab in combination with TCS on severity and extent of AD, itch, and health-related quality of life compared with placebo in combination with TCS. To assess the safety of tralokinumab in combination with TCS when used to treat moderate-to-severe AD for 32 weeks.
