Treatment: Drugs: Tralokinumab
Tralokinumab is a human recombinant monoclonal antibody of the immunoglobulin G4 (IgG4) subclass that specifically binds to human interleukin (IL) 13 and blocks interaction with the IL-13 receptors.

Treatment: Drugs: Placebos
Placebo contains the same excipients in the same concentration only lacking tralokinumab.

Summary
Brief summary
Primary objective:

To evaluate the efficacy of subcutaneous (SC) administration of tralokinumab compared with placebo in treating adolescent subjects (age 12 to \<18 years) with moderate-to-severe AD.

Secondary objectives:

To evaluate the efficacy of tralokinumab on severity and extent of AD, itch, and health-related quality of life compared with placebo.

To investigate the safety, immunogenicity, and tolerability of SC administration of tralokinumab compared with placebo when used to treat adolescent subjects (age 12 to \<18 years) with moderate-to-severe AD.
