Overview
Brief Summary
Primary Objective:
To evaluate the efficacy of dupilumab monotherapy compared to placebo treatment in adult participants with moderate-to-severe atopic dermatitis (AD).
Secondary Objectives:
- To evaluate the safety of dupilumab monotherapy compared to placebo treatment in adult participants with moderate-to-severe AD.
- To evaluate the effect of dupilumab on improving patient reported outcomes (PROs).
- To evaluate dupilumab immunogenicity.
Detailed Description
The maximum study duration was 33 weeks per participants, including a screening period of up to 5 weeks, a 16-week randomized treatment period, and a 12-week follow-up period.

Outcomes
Primary Outcomes
Number of Participants With Investigator's Global Assessment (IGA) Score of "0" or "1" and Reduction From Baseline of Greater Than or Equal to (>=) 2 Points at Week 16
Time Frame: Baseline, Week 16
The IGA is an assessment instrument used to rate the severity of AD globally based on a 5-point scale ranging from (0 = clear; 1 = almost clear; 2 = mild; 3 = moderate; 4 = severe), higher score indicated higher severity.
