Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Tralokinumab+TCS
Week 0 to Week 16: Tralokinumab will be given as subcutaneous injections.
Participants will receive tralokinumab loading dose on Day 0 followed by multiple tralokinumab injections.
The last administration will occur at Week 14. Topical corticosteroids (TCS) will be administered as needed.
|
Tralokinumab is a human recombinant monoclonal antibody of the immunoglobulin G4 subclass that specifically binds to human interleukin-13 (IL-13) and blocks the interaction with IL-13 receptors.
It is presented as a liquid formulation for subcutaneous administration.
TCS administered as needed.
|
Placebo Comparator: Placebo+TCS
Week 0 to Week 16: Placebo will be given as subcutaneous injections.
Participants will receive placebo loading dose on Day 0 followed by multiple placebo injections.
The last administration will occur at Week 14. Topical corticosteroids (TCS) will be administered as needed.
|
Placebo contains the same excipients in the same concentration only lacking tralokinumab.
TCS administered as needed.

Week 0 to Week 16
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Scoring Atopic Dermatitis (SCORAD) Total Score From Baseline to Week 16
Time Frame: Week 0 to Week 16
|
SCORAD is a validated tool to evaluate the AD disease based on 3 components:
The SCORAD was calculated as: A/5+7B/2+C. The maximum total score is 103, with higher values indicating more severe disease. |
Week 0 to Week 16
|
Change in Dermatology Life Quality Index (DLQI) Score From Baseline to Week 16.
Time Frame: Week 0 to Week 16
|
DLQI consists of 10 items addressing the participant's perception of the impact of their skin disease on different aspects of their health-related quality of life over the past week, such as dermatology-related symptoms and feelings, daily activities, leisure, work or school, personal relationships, and the treatment.
Each item is scored on a 4-point Likert scale (0=not at all ⁄ not relevant; 1=a little; 2=a lot; 3=very much).
The total score is the sum of the 10 items (ranging from 0 to 30), with higher scores indicating poorer health-related quality of life.
|
Week 0 to Week 16
|
Reduction of Worst Daily Pruritus Numeric Rating Scale (NRS) Score (Weekly Average) of at Least 4 From Baseline to Week 16
Time Frame: Week 0 to Week 16
|
Participants assessed the itch for the past 24 hours using the Worst Daily Pruritus NRS, consisting of 11 points, with 0 indicating 'no itch' and 10 indicating 'worst itch imaginable'.
|
Week 0 to Week 16
|
At Least 90% Reduction in EASI (EASI90) at Week 16
Time Frame: Week 0 to Week 16

POEM consists of 7 items, each addressing a specific symptom (itching, sleep, bleeding, weeping, cracking, flaking, and dryness).
Participants score how often they have experienced each symptom over the previous week, using a 5-point categorical response scale (0=no days; 1=1 to 2 days; 2=3 to 4 days; 3=5 to 6 days; 4=every day).
The total score is the sum of the 7 items (ranging from 0 to 28) and reflects disease-related morbidity; higher scores indicate more severe disease.

Week 0 to Week 16
|
Number of Treatment-emergent Adverse Events From Baseline to Week 16 Per Subject
Time Frame: Week 0 to Week 16
|
Number of events divided by patient years of exposure (= rate).

Week 0 to Week 16
|
Number of Subjects With Presence of Treatment-emergent Anti-drug Antibodies (ADA) From Baseline to Week 16

Anti-tralokinumab antibody levels were analyzed using a validated bioanalytical method.
Positive treatment-emergent ADA was defined as ADA negative or missing at baseline, and at least one positive post-baseline ADA response.
