Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Participants Investigators
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 healthcare professional at the site who will not be involved in the management of trial subjects and who will not perform any of the assessments.

Study Groups
