251 participants in 3 patient groups

Placebo
Experimental group
Description:
Participants received placebo matching dupilumab once every 2 weeks (Q2W) (including doubling the amount of placebo on day 1 to match the loading dose). In order to maintain blinding for the study, participants in the \<60 kilogram (kg) weight stratum received, in a 1:1 ratio, either placebo matching 200 milligram (mg) dupilumab (including doubling the amount of placebo on day 1 to match the loading dose) or placebo matching 300 milligram (mg) dupilumab (including doubling the amount of placebo on day 1 to match the loading dose). In the ≥60 kg weight stratum, the participants randomized to the placebo group received placebo matching 300 mg dupilumab (including doubling the amount of placebo on day 1 to match the loading dose).
Treatment:
Drug: Placebo
Dupilumab 300 mg Q4W
Experimental group
Description:
Participants received once every 4 weeks (Q4W) subcutaneous (SC) injections of 300 milligrams (mg) dupilumab following a loading dose of 600 mg on day 1. In order to maintain blinding, all participants received an injection once every 2 weeks (Q2W) from day 1 to week 14. Participants received placebo 2 milliliter (mL) injection at the weeks dupilumab was not given.
Treatment:
Drug: Dupilumab
Dupilumab 200 mg or 300 mg Q2W
Experimental group
Description:
Participants with baseline weight \<60 kg received once every 2 weeks (Q2W) subcutaneous (SC) injections of 200 milligrams (mg) dupilumab following a loading dose of 400 mg on day 1. Participants with baseline weight ≥60 kg received Q2W SC injections of 300 mg dupilumab following a loading dose of 600 mg on day 1.
Treatment:
Drug: Dupilumab
