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.

Atopic Dermatitis Drug: Tralokinumab Drug: Placebo Phase 3

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 380 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Masking Description:

Neither the subject nor any of the investigator or LEO staff who are involved in the treatment or clinical evaluation and monitoring of the subjects will be aware of the treatment received. The packaging and labelling of the investigational medicinal products (IMPs) will contain no evidence of their identity.

Since tralokinumab and placebo are visually distinct and not matched for viscosity, IMP will be handled and administered by a qualified, unblinded health-care professional at the site who will not be involved in the management of trial subjects and who will not perform any of the assessments.

Primary Purpose: Treatment

Primary Outcome Measures :
  1. Participants With Investigator's Global Assessment (IGA) Score of 0 (Clear) or 1 (Almost Clear) at Week 16 [ Time Frame: 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).

  2. Participants Achieving at Least 75% Reduction in Eczema Area and Severity Index (EASI) at Week 16 [ Time Frame: 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.

    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.

  2. Change in Scoring Atopic Dermatitis (SCORAD) From Baseline to Week 16 [ Time Frame: 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.

  3. Change in Dermatology Life Quality Index (DLQI) Score From Baseline to Week 16 [ Time Frame: 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.

  4. Frequency of Anti-drug Antibodies (ADA) [ Time Frame: Week 0 to Week 16, Week 16 to Week 32 ]

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.

  5. Amount of Topical Corticosteroid (TCS) Used Through Week 16 Assuming no TCS Used From the Non-returned Tubes [ Time Frame: Week 1-2 to Week 15-16 ]
    Assessed as the amount of TCS weighed from previous visits, assuming no TCS was used from the non-returned tubes. Measurements were collected as TCS weight (g) between the visits.

  6. Amount of Topical Corticosteroid (TCS) Used Through Week 16 Assuming All TCS Used From the Non-returned Tubes [ Time Frame: Week 1-2 to Week 15-16 ]
