Arms

• Experimental: Dupilumab
  Participants received dupilumab at a loading dose of 600 milligrams (mg), subcutaneously (SC) on Day 1 followed by dupilumab 300 mg once every 2 weeks (q2w) for 24 weeks added to background therapy of topical corticosteroids/topical calcineurin inhibitors (TCS/TCI) at stable dose.
• Placebo Comparator: Placebo
  Participants received placebo matched to dupilumab 600 mg (loading dose), SC on Day 1 followed by placebo matched to dupilumab 300 mg q2w for 24 weeks added to background therapy of TCS/TCI at stable dose.

Primary Outcome Measure

Percentage of Participants With Improvement (Reduction) in Worst Itch Numeric Rating Scale (WI-NRS) Scores by Greater Than or Equal to (>=) 4 Points From Baseline to Week 24 [ Time Frame: Baseline, Week 24 ]
