Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Dupilumab
Treatment: Drugs - Placebo (for Dupilumab)
Other interventions - Topical Corticosteroid (TCS)

Experimental: Placebo qw - Two subcutaneous injections of Placebo (for Dupilumab) as a loading dose on Day 1 followed by a single injection weekly (qw) from Week 1 to Week 51.

Experimental: Dupilumab 300 mg q2w - Two subcutaneous injections of Dupilumab 300 mg (for a total of 600 mg) as a loading dose on Day 1, followed by placebo (for Dupilumab) alternating with single 300 mg injection of Dupilumab every 2 weeks (q2w) from Week 1 to Week 51. During weeks in which Dupilumab was not administered, participants received placebo.

Experimental: Dupilumab 300 mg qw - Two subcutaneous injections of Dupilumab 300 mg (for a total of 600 mg) as a loading dose on Day 1, followed by a single 300 mg injection of Dupilumab qw from Week 1 to Week 51.


Treatment: Drugs: Dupilumab
Subcutaneous injection in the different quadrants of the abdomen (avoiding navel and waist areas) and upper thighs

Treatment: Drugs: Placebo (for Dupilumab)
Subcutaneous injection in the different quadrants of the abdomen (avoiding navel and waist areas) and upper thighs

Other interventions: Topical Corticosteroid (TCS)
All participants were required to treatment with a (TCS) using a standardized regimen. It was recommended that participants use triamcinolone acetonide 0.1% cream or fluocinolone acetonide 0.025% ointment for medium potency, and hydrocortisone 1% cream for low potency.
